View PresentationCoinfection affects up to 60% of patients hospitalized influenza-like illnesses, however, the role of the innate immune response in coinfections is not understood. Interferons, part of the innate immune response, are a type of chemical released by infected cells that can help establish an antiviral state in cells by increasing resistance to infection and reducing production of viruses. Although the increased resistance to infection can help suppress both viruses, the reduction in the production of one virus may aid in increasing the growth of another virus during coinfection due to less competition. We will use a mathematical model to examine the interaction via interferons between respiratory syncytial virus (RSV) and influenza A virus (IAV) during coinfections. This model will measure viral titer, duration of the viral infection, and interferon production allowing us to understand how interferon production of one virus helps or hinders the secondary virus.

View PresentationDue to the enormity of different forms of cancer and the increase in cancer rates globally, it is essential to continually develop more advanced methods of early and localized detection of cancer cells, as well as methods of targeted drug delivery. As a result, a vast amount of research has gone into the use of nano-materials such as graphene quantum dots (GQDs) as the basis for a wide variety of biomedical sensing and treatment applications. While many diagnostic biomarkers have been detected using modified GQDs, one biomarker that has not yet been successfully detected or targeted using GQDs is Transgelin-2. Transgelin-2 is a unique actin-binding protein that has been projected to be a useful biomarker and target of treatment for many different forms of cancer, as well as asthma and immune diseases such as lupus. Herein I review the structure of the Transgelin-2 protein, novel methods of GQD modification to sense cell membrane surface proteins, and ultimately determine the viability of GQDs as a method for detecting and targeting Transgelin-2. Furthermore, I develop a possible methodology by which these biophysical applications may be tested.

View PresentationThrough the use of large-scale surveys, astronomers are able to investigate Milky Way galaxy evolution, both dynamically and chemically; however, determining reliable stellar ages has been elusive. Star clusters are the most reliable way to measure ages of stars, and new surveys are measuring detailed chemistry for cluster stars that may be able to be correlated with age. For our study, we are using carbon and nitrogen abundances within red giant stars as age indicators. Using the Open Cluster Chemical Abundances and Mapping (OCCAM) survey, we utilized stellar parameters and abundances, and created a uniform empirical relationship between stellar ages and carbon-to-nitrogen abundances using star clusters. This new calibration will allow us to determine reliable ages for over 100,000 stars across the Milky Way galaxy, allowing us to measure the chemical evolution of the Galaxy.

View PresentationAntimicrobial action of micro- and nanoscale ZnO particles has been documented, but the fundamental physical mechanisms driving these actions are still not identified. We hypothesize that one of the key mechanisms behind the antibacterial action of ZnO is rooted in interactions between ZnO surfaces and extracellular material. An investigation was done of the biological components of that interaction using diffusion theory and more specifically Brownian motion computational models to look at the interaction of Zn+2 and O-2 ions with staphylococcus aureus bacteria. The analysis allowed us to find a correlation between the thickness of the staphylococcus aureus bacteria and the amount of the zinc and oxygen ions present in the solution.

View PresentationNano- and microscale zinc oxide (ZnO) have demonstrated potential for applications in electronic, pharmacological and chemical industries among others. At these scales, surface properties dominate, rendering surface defects highly influential. Consequently, understanding of defect- related phenomena are crucial to achieving impactful figures of merit. Many optoelectronic properties of ZnO relevant for applications have been linked to defect-related visible luminescence. Its fundamental origins are still being debated, with attributions to oxygen vacancies, zinc vacancies, oxygen antisites, donor-acceptor pairs, etc. In our studies, we contribute to this discussion by probing the relationship between crystal morphology and this luminescence. We conducted optoelectronic studies to characterize the effects of remote oxygen plasma treatment on hydrothermally-grown microscale ZnO samples with controlled morphology as a means to help elucidate the nature of the visible emission. We report on the observed changes in the photoluminescence spectra indicative of the relationship between surface defects, morphology, and electronic structure of ZnO.

View PresentationWith the development of personalized cancer medicine and moving away from a conventional biopsy, there is a need in creating a multifunctional platform for cancer diagnosis and treatment monitoring. Sonography offers many advantages over standard methods of therapeutic imaging due to its non-invasiveness, deep penetration, high spatial and temporal resolution, low cost, and portability. The benefits of the ultrasound method make contrast agents an ideal platform for the efficient strategy of cancer diagnostic and therapy. In this work, we developed metal-doped graphene quantum dots that demonstrate high-contrast properties in ultrasound brightness mode. The successful imaging enhancement was observed in tissue phantom and chicken breasts tissue. The relatively small size of the metal-doped graphene quantum dots makes them easily be internalized into the cells, while functional groups on their surface allow binding a cancer-targeted marker and therefore be used as a cancer-targeted delivery. By a combination of imaging and targeting capabilities, ultrasound contrast agents based on metal-doped graphene quantum dots enable desired cancer-focused nanotherapeutic and imaging approaches.

View PresentationFor billions of years, our Milky Way galaxy has churned out countless stars. However, the best star-forming days of our galaxy are long gone and our galaxy is in a midlife crisis! It’s running out of gas to make new stars, and extraneous resources are scarce. Worse yet, high stellar winds might eject some gaseous material, such as the Smith Cloud. After it was ejected, the Milky Way’s gravity caused this cloud to reverse course and fall back toward our Galaxy. The Smith Cloud is now only 40,000 light-years away and carries with it the equivalent of over 1 million Suns worth of material. As it makes the journey back to our Galactic Plane, it must endure heavy winds that have temperatures in excess of 1 million degrees Celsius from the Milky Way galaxy’s coronal gas. I have already measured the amounts of various ions in adjacent cloud fragments positioned on the side of the Smith Cloud using Hubble Space Telescope observations. These ions include C+, Si+, Si2+, Si3+ , and S+. I will then determine the effects that these high winds have on the adjacent fragments and the trailing wake of the Smith Cloud to better understand the perils that gas clouds must undergo to reach massive galaxies.

View PresentationDwarf galaxies are the building blocks larger galaxies. Their shallow gravitational potentials makes them extremely sensitive to explosions of stars. To understand how dwarf galaxies form and evolve, we must study their formation, evolution and fate in a range of environments. Located 13 million light years away, Centaurus A is the closest massive elliptical galaxy making it ideal for investigating the effects of local environment on the formation and evolution of dwarf galaxy populations. We model the dwarf satellite populations of Centaurus using a suite of high resolution N-body simulations and the semi-analytic model (SAM) Galacticus (Benson, 2010). We determine the best fit parameters for well studied Milky Way satellite, before applying those parameters to generate simulated satellites around our Centaurus A's analog. Given the relatively low computational cost of N-body simulations and SAMs, we are able to explore the effects of uncertainties in the Centaurus A system, including its relatively unconstrained mass. Here we present initial results from our study for the first Centaurus A like galaxy.

View PresentationFifty percent of stars in the night sky are actually binary star systems, but finding and characterizing them requires significant data, time, and analysis. Studying the brighter star of the pair is fairly straightforward, but the secondary is commonly hidden. Using the infrared spectroscopy data from the Sloan Digital Sky Survey combined with the WIYN Open Cluster Survey, we create a longer baseline with which we can better characterize these stars. The Joker, a new Monte Carlo analysis technique, will help us reveal the hidden binary stars by producing solutions for the orbits of the systems. By finding new binary stars, we can better understand the demographics and composition of our chosen star cluster, NGC 6819, and also learn more about each individual companion of the systems.

View PresentationNostalgia, a sentimental longing for the past, increases prosocial behavior. Research has demonstrated that when a former competitive athlete reflects on their time participating in their sport, they experience feelings of nostalgia. Applying the prosocial nature of nostalgia to an athletic domain, it was hypothesized in the current study that sport-specific nostalgia would predict greater sportsmanship attitudes among athletes. To test this, we primed former competitive athletes with sport nostalgia by instructing them to write about a memory from playing their sport. Then they completed items about their sportsmanship attitudes, such as respecting opponents and officials. Results showed that nostalgia-primed participants reported greater sportsmanship attitudes compared to a control group. This is consistent with research showing that nostalgic reflection increases prosocial attitudes and behavior. In future work we plan to examine these findings in current competitive athletes to give further insight into the role that nostalgia plays in sport settings.

View PresentationBackground: Reward loss is accompanied by a stress response affecting emotion and health. Problem: A comprehensive map of brain activity, or connectome, during an episode involving reward loss remains to be worked out. A connectome is being developed using the protein c-Fos expressed in recently activated neurons. Method: Experimental animals were exposed to reward loss (high-to-low sucrose and pellet downshift), whereas control animals had access only to the small or only to the large reward. c-Fos expression was measured in brain slices obtained after the reward loss event using immunohistochemistry. Brain activity levels in experimental and control animals were determined based on c-Fos expression in several key brain areas. Results: c-Fos expression was found to be higher in areas involved in negative emotion and lower in areas involved in reward processing in downshifted vs. unshifted groups. Contribution: This novel approach will continue to help identify the brain connectome underlying reward loss, that is the set of excited and inhibited areas when the organism is experiencing a loss.

View PresentationResearch suggests that cannabidiol (CBD) can act as an anxiolytic when injected (Blessing et al, 2015). We investigated whether these findings could be replicated in rats using chronic (12 day) voluntary oral consumption of non-pharmaceutical grade CBD oil at 20mg/kg. A control group consumed distilled water. An elevated plus maze (Test 1), open field (center vs. outer, light vs. dark, Test 2 and 3), and running wheel (Test 4) were used to examine the anxiolytic effect of CBD beginning on day 12 of administration and two hours after consumption. One test occurred each day. It was hypothesized that CBD rats would spend more time in the open arms of the elevated plus maze than the control group, and more time in the center and lit areas of the open field compared to the control rats. For the running wheel, we expected the CBD rats to turn the wheel more times than the control group. Results revealed that in the open field, the CBD group spent more time in the center compared to the control group, as was expected. There were no other differences between groups. These results are discussed with respect to administration route, timing of test, and type of test.

(Presentation is private)Varied practice, or studying many different examples of a given topic, can be a more effective method for learning a concept compared to studying one example repeatedly, as demonstrated in motor learning (e.g., Kerr & Booth, 1978) and category learning (e.g., Wahlheim et al., 2012). The present study examined how varied practice affects learning vocabulary from examples used in sentences. Although potentially beneficial for long-term understanding, varied practice can make initial vocabulary learning challenging because the example sentences for a given term may vary greatly. The current study presented participants with a sentence and asked them to select the correct vocabulary word that completed the sentence. For half of the vocabulary terms, participants were tested on that vocabulary word in the same sentence repeatedly (constant practice); for the other half of the words, participants were tested on that vocabulary word in different sentences (varied practice). Participants were also asked to answer questions about their attention during the task. After a short delay, participants took a final test to investigate how well they could identify the studied vocabulary words in novel sentences. The results will be discussed in terms of desirable difficulties, the distinction between learning and performance, and whether the type of practice may influence attention.

View PresentationLearning and correctly remembering health information is important at all ages, and it can be particularly important in later adulthood (65+ years old). Thus, interventions focused on identifying methods to improve young and older adults’ health knowledge and memory for medication information are valuable. We developed a cognitive intervention relying on methods that have been identified to be effective for enhancing learning. Specifically, prior research has established that retrieval practice (recalling information from memory) can be a powerful tool for learning other kinds of information. Our goal was to evaluate the degree to which a retrieval practice intervention would improve younger and older adults’ self-regulated learning of medication side effects. Younger adults from TCU and older adults from the community were recruited to participate. Participants who received the intervention were given information about repeated retrieval practice that emphasized the effectiveness of this strategy for improving memory. Specifically, the intervention indicated that they should recall each medication’s side effects correctly 3 times during learning, and they should continue to space their retrieval practice until they met this goal. All participants learned medication names paired with a side-effect. They made decisions about when to study, engage in retrieval practice, and stop learning the list of medication-side effect pairs. Younger and older adults’ who received the intervention made better study decisions relative to those who did not. Further, the intervention enhanced both younger and older adults’ memory for medication side effects relative to control conditions. These outcomes suggest that our evidence-based intervention can help young and older adults learn and remember critical health information, which may assist them in monitoring for adverse outcomes during medication usage.

View PresentationDevelopmental Dyslexia (DD) is a heritable disorder that effects approximately 5-12% of children (Shaywitz et al., 1990) and persists in 4-6% of adults (Schulte-Korne & Remschmidt, 2003). In those with dyslexia, reading dysfunction is caused by phonological impairments that may result from neurological low-level sensory-processing mechanisms. Previous research suggests that rapid autonomized naming (RAN) deficits are the most reported deficit in adults with dyslexia (Araújo, et al., 2019), however it is unknown whether the RAN deficit is caused by general rapid processing deficits or a specific letter-sound binding problem. This experiment was designed to address this unknown question by measuring rapid visual processing deficits and their relation to reading skills in children with dyslexia. Children (N=103) were recruited during the COVID-19 pandemic as part of a larger study of rapid stimulus processing in dyslexia. Out of the 103 children screened, 77 qualified for use in the study (33 neurotypical, 33 dyslexia, and 11 compensated dyslexia). Children completed two visual processing tasks online. The first was a rapid serial visual perception task (RSVP; Amador-Campos et al., 2015) which evaluates rapid stimulus processing of one or more symbol and letter. The second was a visuo-spatial working memory task (VSWM; Sander, Werkle-Bergner, & Lindenberger, 2011) that evaluates working memory and visual acuity at different speeds. Accuracy and reaction times were measured for each task. While we found no group differences on any task or condition, there were main effects of target number for RSVP accuracy and of set size and speed for VSWM. These results demonstrate that the tasks were adequately difficult but that those with dyslexia did not exhibit specific deficits on either task, even when the stimuli were printed letters. This suggests that RAN deficits in children with dyslexia may not originate from rapid visual perception deficits, but some other neural mechanism.

View PresentationRelationship between Self-Care Inquiry and Stress Levels In Adolescents with Substance Use Disorders
Adolescents living with substance use disorders are presented with a multitude of challenges when confronted with the reality of recovery from their addiction. Despite numerous interventions used to assist adolescents as they seek rehabilitation, few interventions focus on everyday stressors or triggers that contribute to substance use. Research has shown that stress significantly impacts substance use. This study aims to evaluate whether inquiring about self-care strategies used by adolescents seeking recovery from a substance use disorder will reduce stress levels, thus improving chances of adolescents maintaining recovery. Adolescents participating in outpatient treatment at a recovery facility were recruited for this study and were asked to fill out surveys once a week for four weeks about their level of stress and activities that they were doing for self-care.

View PresentationRomantic relationships are a popular subject in the psychological research realm, but their social counterparts, singles, are overlooked. Further, whereas loneliness is well-studied, existential isolation (EI), the subjective sense that one is alone in one’s experience and that others cannot understand their perspective, is a construct that could provide insight to singles. Our research will examine single adults and how they might experience EI if they do not have single friends who can reasonably share their same experience (i.e., if most of them are in relationships). Single participants will estimate the proportion of their social circle (friends and family) who are single vs. in relationships. We predict that singles whose friends are mostly in romantic relationships will experience higher EI. On the other hand, we predict that single people with mostly single friends will not experience the same high level of EI. We will also measure EI in comparison to different well-being measures (e.g., self-esteem, happiness). It is hypothesized that singles will experience higher EI and lower well-being if most of their friends are not single.

Authors: Maddy Filippi, Deborah Rafferty, Naomi Ekas, Chrystyna Kouros
Introduction: Mothers and fathers of autistic children face many mental health and relationship challenges compared to parents of neurotypical children, including higher levels of stress (e.g., Benson, 2006; Weitlauf et al., 2014), more marital dysfunction (e.g., Shtayeermman et al., 2013; Sim et al., 2016), and increased likelihood of divorce (e.g., Hartley, 2010; Shtayermman, 2013). The sudden closure of schools and transitioning to online services at the beginning of the COVID-19 pandemic may have exacerbated the stress levels of parents with a disability, including negatively affecting various aspects of home life (Marchetti et al., 2020). The purpose of this study was to compare differences in marital relationship quality and psychological distress in mothers and fathers of autistic children at multiple points throughout the COVID-19 pandemic. Additionally, the mental health and marital satisfaction in mothers and fathers of autistic children were compared to population norms at all timepoints.
Methods: Mothers and fathers of autistic children who were part of a larger longitudinal study participated in a supplemental study examining the ongoing effects of the COVID-19 pandemic. To qualify for the main study, parents had to be married or living together for a year, have an autistic child that lived with them 50% of the time, and be able to read and speak English. From the original sample of 119 couples, 94 mothers and 58 fathers answered surveys about their mental health (anxiety, stress, dysphoria), marital functioning (conflict and satisfaction), and the symptom severity of their autistic child at three time points (April, July, and October 2020) after the start of the COVID-19 pandemic.
Results: A series of independent t-tests examined the differences between mothers’ and fathers’ reported levels of mental health, marital functioning, and child symptom severity. At all timepoints, mothers’ parenting responsibilities and anxiety levels were significantly higher than fathers’, ps ≤ .043. Mothers’ levels of stress and dysphoria were significantly higher in October 2020 than fathers’, ps ≤ .012. Compared to pre-pandemic population norms, mothers reported significantly higher stress at all timepoints (ps ≤ .006), while fathers only reported significantly higher levels of anxiety in April 2020 (p ≤ .001). Fathers also reported lower levels of dysphoria compared to population norms at all timepoints (ps ≤ .016).
Conclusion: As a result of the COVID-19 pandemic, mothers of autistic children appeared to have more negative outcomes compared to fathers of autistic children. Mothers reported more parenting responsibilities compared to fathers, as well as higher rates of stress. In October 2020 when school districts re-opened, mothers reported higher levels of stress and dysphoria compared to fathers. Further, compared to pre-pandemic populations, parents of autistic children reported more stress and fathers reported reduced dysphoria. Overall, parents of autistic children appeared to face negative outcomes as a result of the COVID-19 pandemic and displayed higher rates of stress and dysphoria than parents at pre-pandemic populations. However, any conclusions generated from data reported by fathers are limited based on the reduced sample size.

Examining The Mediating Role of Self-Esteem on the Relationship Between Adverse Childhood Experiences and Anxiety
Holli Fullbright, Michelle Coad, Lindsay Dills, Porter Maggiore
Texas Christian University, Fort WorthBackground: Adverse Childhood Experiences (ACEs) are traumatic events during childhood that have lasting effects into adulthood, being associated with poorer health and psychosocial well-being. The present study investigates the relationship between ACEs, self-esteem, and anxiety among people with a history of justice involvement. We predicted that ACEs would be negatively correlated with self-esteem. Self-esteem, in turn, would be negatively correlated with anxiety.
Methods: Data were collected from 216 people with a self-reported history of substance use and justice-involvement using Amazon’s Mechanical Turk (MTurk). Participants were required to be 18 years of age or older and fluent in the English language. Eligible participants who consented to participate in the study were asked to complete a 25-minute online survey and were compensated $1 for their time.
Results: Analyses revealed that more childhood adversity was significantly related to both higher anxiety and lower self-esteem. Further, self-esteem was significantly related to anxiety while controlling for ACEs. When self-esteem was included in the model, the relationship between ACEs and anxiety was no longer significant. In other words, self-esteem statistically mediated the relationship between childhood adversity and anxiety.
Conclusion: Findings indicate that self-esteem may be an important target for treatment among clients with histories of childhood adversity and anxiety. Self-esteem may serve as a protective factor against anxiety for clients who report a history of childhood abuse or neglect.

View PresentationPast research has shown that individuals can think themselves into more extreme attitudes in the absence of learning new information about an attitude object (Tesser, 1978). Less is known, however, about whether certain types of thinking, or thought strategies, are more likely than others to make attitudes more extreme. The current study assessed whether and how a specific type of thought strategy—extrapolating beyond what is known about a social group’s personality traits—can make attitudes more extreme in the absence of new information. Participants first learned moderate trait information about two (fictitious) social groups and then self-generated extrapolations about one of the social group’s traits and reviewed the initial trait information for the second social group. Attitudes were more extreme toward the social group whose initial traits participants extrapolated than the social group whose initial traits participants reviewed. These findings extended past research and theory on the processes by which attitudes can become more extreme in the absence of new information.

View PresentationIntroduction: Some may believe that helicopter parenting and controlling parenting behaviors are the same, but parental control as a parenting style is distinct and separate from helicopter parenting (LeMoyne & Buchanan, 2011). Helicopter parenting is a widely known parenting style that is characterized by the tendency for parents to be over-involved in the lives of their children in attempts to shield children from experiencing pain, discomfort, or failure (Padilla-Walker & Nelson, 2012). Helicopter parenting behaviors have been linked to concerning child outcomes, however, including lowered student academic motivation and achievement (Schiffrin & Liss, 2017), decreased psychological well-being (LeMoyne & Buchanan, 2011), and increased feelings of depression and anxiety (Set, 2020). Parental control, alternatively, is characterized by complete control of the child’s life while expecting compliance with parent demands without exception. Child outcomes as a result of parental control also differ such that these children tend to have greater academic achievement (Watabe & Hibbard, 2014). The goal of the current study was to further explore how parents’ helicopter parenting and controlling parenting behaviors differ in predicting their students’ psychological entitlement. It was hypothesized that both helicopter parenting and controlling parenting behaviors will predict higher student psychological entitlement with helicopter parenting predicting a greater increase.
Methods: Six hundred sixty-five undergraduate psychology students at two Southern private universities were recruited through SONA. Participants answered a battery of online questionnaires about their relationship with their parent, their parent’s personality traits, and their helicopter parenting and controlling parenting behaviors. Additionally, participants answered questions about their own personality traits, academic achievement, and overall well-being.
Results: A simultaneous multiple regression was performed to explore the association between parents’ helicopter parenting and parental control scores on their students’ psychological entitlement scores. The results showed a significant association between helicopter parenting and student psychological entitlement, b = 1.54, SE = .57, t = 2.70, p = .007, R2 = .01, with increases in helicopter parenting scores predicting an increase in student psychological entitlement scores. There was also a marginally significant association between parental control and child psychological entitlement, b = -.10, SE = .05, t = 1.95, p = .052, R2 = .01, with increases in parental control scores predicting a decrease in child psychological entitlement scores. These results suggest that helicopter parenting behaviors predict higher student psychological entitlement whereas controlling parenting behaviors predict lower student psychological entitlement. For exploratory purposes, another variable, student gender, was entered into the model to assess whether gender was a predictor of student psychological entitlement. Gender was dummy coded using females as the reference group coded as 0. The results showed that there was no significant association between students’ gender and psychological entitlement scores, b = .38, SE = .83, t = .46, p = .646, R2 = .000, suggesting that gender is not associated with one’s psychological entitlement.
Discussion: Helicopter parenting and parental control are two, distinct styles of parenting that result in differing effects on student psychological entitlement. The results of the study support the hypothesis that helicopter parenting would predict a greater increase in psychological entitlement compared to parental control, however, the results refuted the claim that both parenting styles would predict increases in psychological entitlement as parental control predicted a moderately significant decrease in entitlement. Future research should examine whether these results replicate among more racially diverse and younger samples. Having a richer understanding of the parental contributors to the development of child psychological entitlement over the span of childhood and adolescence will aid professionals in identifying and changing problematic parental behaviors to decrease these outcomes.

View PresentationAssessing staff attitudes and needs in a trauma-informed organization: a mixed-methods study
Background: Prior research has found that high burnout rates are prevalent in organizations that work
with individuals who have experienced trauma. Furthermore, high burnout is associated with secondary
traumatic stress, which can affect staff’s ability to provide care to clients. Therefore, the purpose of the
current study was to identify staff satisfaction and departmental needs at an organization specializing in
family services for those who have experienced trauma.
Methods: An online survey, including qualitative and quantitative questions, was developed via
Qualtrics and emailed to one non-profit organization. The results are comprised of responses from 20
employees.
Result: Overall, the participants rated their organization favorably. The average burnout and secondary
traumatic stress levels were low, which indicates no issues present in these categories. Simple linear
regression was used to test if burnout significantly predicted secondary traumatic stress. It was found
that burnout significantly predicted secondary traumatic stress (β = .57, p = .001). These results were
corroborated by qualitative data from staff, where staff demonstrated a general positive experience
within their work environment. However, when prompted staff identified aspects of the organization
that could be improved: the low number of staff employed, staff coordination and training, open
communication between coworkers and supervisors, reinstating staff events, and increased access to
mental health services.
Limitations: This study is limited by its small sample size and may not be generalizable to other
organizations, as only one organization was assessed.
Conclusion: The current study found that burnout predicts secondary traumatic stress. Overall, the staff
assessed feel that their organization is a positive work environment but identified areas for
improvement such as the number of staff, training, communication, the addition of social events, and
access to mental health services. Addressing staff concerns could reduce staff burnout and increase
satisfaction. Additionally, ensuring that staff needs are met could also benefit clients, as staff and
organizational factors are related to the quality of services.

View PresentationA deterministic position claims that all events, including human choice behavior, are caused by other events (e.g., a person’s environment and past experiences). In contrast, indeterminism, or free will, maintains that a decision can emanate solely from within (i.e., independent of external influences). Previous research found that participants who read deterministic passages cheated more on an arithmetic test than those who read free will passages (Vohs & Schooler, 2008). The current research examined how the valence of the outcomes in passages influenced behavior (i.e., cheating). Experiment 1 examined how positive or negative participants rated passages that described an action within a deterministic or indeterministic universe that ended in a positive (e.g., a rescued child), negative (e.g., a lost child), or neutral (e.g., a child sitting) outcome. In Experiment 2, participants read one of the above mentioned passages followed by an additional 9 passages and comprehension questions. After reading each passage, a click to a “Show Questions” button made the passage disappear and the comprehension questions appear. To manipulate cheating, on some passages, the questions were automatically displayed while the passage was visible. Participants could answer the questions with the passage visible or click “Show Questions” to remove it. Results will be discussed in terms of the reported valence and the number of times “show questions” was clicked.

Authors: Kate Lindig, Deborah Rafferty, Naomi Ekas, and Chrystyna Kouros
Introduction: Mental health of mothers of children on the autism spectrum has been extensively studied (e.g., Sawyer et al., 2009). Prior studies have found connections between the time commitment and pressure experienced by mothers of autistic children and poor mental health outcomes (Liu et al., 2020). Mealtimes for children on the autism spectrum often create stress for mothers (Ausderau & Juarez, 2013). Children on the autism spectrum often experience various difficulties with feeding and mealtime behaviors, such as limited food variety (Curtin et al., 2015), food neophobia (Kuschner et al., 2015), high rates of food refusal and more restricted food repertoire compared to neurotypical children (Bandini et al., 2019), as well as increased disruptive behaviors around mealtimes (Curtin et al., 2015). While little research has examined how feeding behaviors in autistic children impact mothers’ mental health (e.g., Ausderau & Juarez, 2013), it is possible that these behaviors may exacerbate negative mental health outcomes as mothers spending hours attempting to help their children eat with little fruition likely causes feelings of stress and anxiety. Therefore, this study aims to examine how food restrictiveness and disruptive behavior during mealtimes for children on the autism spectrum affects measures of maternal mental health during the COVID-19 pandemic, which has the potential to elevate stress-levels and other negative mental health outcomes for mothers.
Method: Ninety-seven mothers with a child on the autism spectrum served as participants for this study. All mothers participated in October 2020 as a follow-up to a larger study that began prior to the COVID-19 pandemic. Mothers were mostly white, non-Hispanic (77%), college-educated (45%), with a yearly income greater than $40K (90%). Mothers answered surveys about their children’s mealtime behaviors (BAMBI) and their own mental health (IDAS, NIH PROMIS).
Results: Two separate multiple regressions were performed to examine associations between disruptive mealtime behaviors, such as refusing to stay seated or screaming, and maternal dysphoria and stress. Results indicated a significant, positive association between the number of disruptive behaviors a child or adolescent with ASD exhibited during mealtimes and maternal self-reports of dysphoria, b = 1.24 (SE = .60), t = 2.05, p = .04, R2 = .05, while controlling for everything else in the model. Similarly, there was a significant, positive relation between disruptive mealtime behaviors and maternal self-reports of stress, b = 1.66 (SE = .82), t = 2.02, p = .047, R2 = .09. The relations between limited variety of food and the study outcome variables were non-significant, ps ≥ .09.
Discussion: Autistic children’s disruptive mealtime behaviors were associated with poor maternal mental health outcomes, specifically higher depressive symptoms and greater stress. Consequently, finding ways to lower disruptive mealtime behaviors is important, since they have the potential to impact maternal mental health outcomes. Future research should test various mealtime intervention programs to find the most effective ways for parents to minimize their autistic children’s disruptive mealtime behaviors. Additionally, future research should explore the effects of mealtime behaviors on fathers’ mental health outcomes, since they are often present during their autistic children’s mealtimes. Finally, future research should look specifically at how children on the autism spectrum’s mealtime behaviors at the current time compare to those during the first six months of the COVID-19 pandemic, when the present study’s data was collected.

View PresentationBackground
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that causes deficits in reciprocal social communication and restricted and repetitive patterns of behaviors, interests, and activities (APA, 2013).
Previous work has found disagreement between parents in their perception of characteristics of their child (Duhig et al., 2000). These differences in perception have been termed ‘informant discrepancies’ and have been linked, in neurotypical (NT) families, to phenomena within the family system such as maternal depression and family distress levels (Christensen et al., 1992; Whiffen et al., 1990). Previous work with NT and ADHD children also found that mothers rated their child’s symptoms as more severe than fathers did (Langberg et al., 2010; Christensen et al., 1992). There is, however, a paucity of research examining possible discrepancies between parents of autistic children (Stratis & Lecavalier, 2015). Because the entire family is impacted by characteristics of each individual member, parents of children with autism may differ from parents of NT children and consequently, research utilizing parents of NT children may not generalize to parents of ASD children.
The current study seeks to examine possible patterns of discrepancies in parents’ perception of their child’s internalizing and externalizing behaviors in parents with ASD children. I aim to determine the rate at which parents agree about their child’s internalizing and externalizing behaviors and to determine which parent perceives behaviors as more severe when parents disagree. Lastly, I aim to determine whether discrepancies in parent perception of child behavior predict depression for either parent.
Method
Participants in this multi-site study included 117 mothers and fathers with a child between 10 and 17 years old with autism. Parents were required to be married or cohabitating for at least one year, to be living with their child at least 50% of the time, and to be able to read and speak English. Their children were required to have a community diagnosis of ASD and must not have a co-occurring intellectual disability. Mothers’ average age was 43.15 years (SD = 6.42) and fathers’ average age was 44.99 years (SD = 6.90). The majority of parents were White and reports of annual family income revealed that 47% earned more than $100,000. Families came to the testing site and completed a series of questionnaires.
The Child Behavior Checklist (CBCL: Achenbach, 1999) was used to measure parents’ perceptions of their child’s internalizing and externalizing behaviors. The CBCL contains a total of 73 items and two subscales; one for internalizing behaviors (mothers, α = .87; fathers, α = .86) and one for externalizing behaviors (mothers, α =.92; fathers, α = .91). Using a three-point Likert-type scale, parents were asked whether statements about their children were not true, somewhat true, or always true in the last two months. Parent depression was measured using the Inventory of Depression and Anxiety Symptoms (IDAS; Watson et al., 2007). This 64 item measure uses a five point Likert-type scale (1 = not at all, 5 = extremely) to measure how true statements are of the participant in the previous two weeks.
Results
Parent scores were considered to be discrepant if they were more than half of a standard deviation apart. Raw scores were converted to Z scores in SPSS and the difference between Z scores was calculated. Analyses revealed that about half of parents agreed about their child’s symptoms while half disagreed for both internalizing and externalizing symptoms. Additionally, when parent did disagree, fathers rated behavior as more severe about half of the time, while mothers rated behavior as more severe the other half of the time (see Table 1 for precise descriptives).

Agreement groups Percentage Agreement groups Percentage
In agreement 50.90 In agreement 50.90
Mothers > fathers 24.10 Mothers > fathers 24.10
Fathers > mothers 25.00 Fathers > mothers 25.00Further analyses will be conducted using polynomial regression with response surface analysis to determine whether discrepancies in parent perception of their child’s internalizing or externalizing symptoms predict depression for either parent.
Discussion
Results revealed that parents agreed about their child’s symptoms about half of the time for both internalizing and externalizing behaviors. Additionally, in instances where parents disagreed, mothers rated behaviors higher than fathers half of the time and lower than fathers half of the time for both internalizing and externalizing behaviors. This is inconsistent with prior work using parents of NT children, which found that mothers tended to rate child behavior higher than fathers. Further work needs to assess both the potential factors contributing to each discrepancy type and possible individual and family outcomes associated with each type.
Analyses will be run before the conference to determine whether the discrepancies in parents’ perception of their child’s symptoms predict depression for the mothers or fathers included in our sample.
