Exploring Parallels Between Lateralized Control of Human Language and the Neural Control of Bengalese Finch Birdsong

Type: Undergraduate
Author(s): Courtney Favaloro Psychology Kaye Urbano Psychology
Advisor(s): Brenton Cooper Psychology

Human speech production and grammatical organization of language is controlled primarily by the left hemisphere of the brain. Broca’s area is a specialized area in the left frontal cortex that is responsible for our ability to construct grammatically correct sentences. Songbirds are studied as an animal model for understanding human language production. Our research sought to explore whether the neural control of birdsong syntax of the Bengalese finch is also lateralized; if so, the Bengalese finch would provide a good animal model to further study syntax generation in humans. To investigate this question, we recorded the birdsongs of 10 different Bengalese finches; then, the HVC (letters used as proper name) brain region, an area thought to control birdsong syntax, was lesioned in either the right hemisphere or the left hemisphere for each bird. Birdsong was then recorded for five months following the surgery. Song syllables were coded and analyzed to measure the syntactic structure of the song. The birdsongs were grouped into a right lesion group and a left lesion group, and they were compared based on three measures of song syntax; sequence stereotypy, sequence consistency, and sequence linearity were measured at each time point. HVC lesion initially disrupted song syntax, but song syntax recovered. There was no significant difference between the left and right lesion groups. When looking at individual time points, the right lesion group seemed to initially lose more syntactic control four days after surgery, but the group differences were non-significant. Overall, the two groups follow a similar trend of recovery. Our results suggest that the HVC control of Bengalese finch song syntax is not lateralized as it is in human speech. The recovery of song syntax following brain injury suggests that other areas of the brain contribute to the generation of syntactic structure of the Bengalese finch song.

The Well-Being of Fathers with Children with Autism Spectrum Disorder

Type: Undergraduate

Advisor(s): Naomi Ekas Psychology

Introduction: Parents of children with autism spectrum disorder (ASD) may experience high levels of stress and face numerous challenges. They also report more mental health problems than parents with typically developing children (Falk, Norris, & Quinn, 2014). In families with children with ASD, differences are found between well-being in mothers as compared to fathers. A recent review found that mothers of children with developmental disabilities, including ASD, reported a higher number of positive experiences than fathers (Kayfitz, Gragg, & Orr, 2010). A possible explanation for this is that fathers may underestimate the influence of outside factors that lead to positive experiences with their child. This could negatively impact the father’s well-being. As research on the fathers in families with children with ASD has expanded within recent years, it is crucial to understand the factors that influence the father’s well-being. The purpose of the current study is to examine child versus parent characteristics as predictors of depressive symptoms in fathers of children with ASD.

Method: Thirty-one fathers of a child with ASD completed an online survey. They completed measures of depressive symptoms (CESD), the broad autism phenotype (BAPQ), adult attachment anxiety and avoidance (ECR-R), child symptom severity (SCQ), child behavior problems (SDQ), work-family conflict, and attitudes about the role of fathers (ROFQ).

Results: To examine the impact of child and parent characteristics on depressive symptoms in fathers of children with ASD a series of correlations were first computed. The results revealed no significant relationship between depressive symptoms and work-family conflict or the child’s symptom severity, ps ≥ .055. However, there was a significant relationship between depressive symptoms in fathers and attachment anxiety, children’s behavior problems, BAP symptoms in the father, and the role of the father, ps ≤ .040. However, when followed up with a multiple regression model, only attachment anxiety, b = 7.89 (SE = 1.87), t = 4.22, p ≤ .001, and the role of the father, b = -.51 (SE = .22), t = 2.35, p = .028, were significant predictors of depressive symptoms.

Discussion: This study helps to identify predictors of well-being in fathers of children with ASD. Specifically, the more attachment anxiety a father reports, the higher his depressive symptoms. It may be necessary to re-frame his attachment representations in order to promote more positive psychological functioning. Fathers who reported that their role is critical to their child’s development reported less depressive symptoms. Fathers are generally less involved in their child with ASD’s treatment (Johnson & Simpson, 2013) and many parent-mediated interventions focus on mothers (Braunstein et al., 2013). Our findings suggest that emphasizing the importance of fathers as an active caregiver may help improve father well-being.

Low Intrinsic Christians Experience Avoidant Attachment to God Following Mortality Salience

Introduction: Research suggests that when reminded of death, individuals cling to their beliefs to cope with the terror associated their inevitable mortality. According to other studies, intrinsic religiousness buffers against existential terror and reduces the need for other terror management defenses as these persons are able to rely on their internalized religious beliefs as a shield and their overall relationship with their divine figurehead (Vail et al., 2012). Other work suggests that a relationship with God can be described as an attachment bond, specifically that an anxious attachment to God is strongly correlated with an extrinsic religious orientation (Rowatt & Kirkpatrick, 2002). The purpose of this study is to examine the association between intrinsic religiosity and attachment to God. Specifically, we hypothesized that low intrinsic individuals would experience a more avoidant attachment to God following mortality salience. High intrinsic persons, however, would display the opposite trend.

Method: Participants consisted of 158 Christians recruited from a medium, private university. Participants were first given the intrinsic religiosity scale (Allport, 1967). In order to manipulate mortality salience, participants completed a neutral or death-related crossword puzzle (Landau, Kosloff, & Schmeichel, 2011). Finally, participants completed the attachment to God inventory to assess for anxious or avoidant attachments to God (Beck & McDonald, 2004).

Results: A moderated regression analysis found a significant interaction between mortality salience and intrinsic religiosity on avoidant attachment to God. More specifically, in the mortality salience condition, individuals with a low intrinsic orientation displayed a more avoidant attachment to God than high intrinsic persons. Additionally, low intrinsic individuals displayed a more avoidant attachment in the mortality salient condition than the control condition. No significant effects emerged for the anxious attachment variable.

Conclusion: The present results suggest that low intrinsic people are unable to rely on their religious beliefs following mortality salience. Specifically, because these individuals do not internalize their beliefs, they become a source of contention instead of an anxiety buffer following mortality salience. Additionally, these results build upon those by Jonas and Fischer (2006) by suggesting that high intrinsic persons are able to fully shield against mortality salience because they have a strong attachment to God.

Effect of Training Type On Learning to Read Novel Orthography

Advisor(s): Tracy Centanni Psychology

Most adults learned to read as children with relative ease and can briefly skim a paragraph and quickly grasp its meaning. However, anecdotal evidence both from educated individuals as well as illiterate adults in underprivileged countries suggests that it is impossible to achieve this same fluency as an adult. Adults learning to read in a new orthography are ‘stuck’ in a struggling state. They never achieve the ability to skim a paragraph and instead, must read every word letter-by-letter. Since this has never been tested in a lab setting, we do not know if this inability to read fluently in a new orthography is due to a change in learning capability with age, or if this has to do with how the new orthography is taught. In the current study, we trained TCU students to recognize letter-to-sound correspondences in Hebrew using either an in-person tutor or a pre-recorded program. We compared letter recognition and fluency over the course of training. We recruited nine individuals in the tutoring group and nine in the automated training program. We evaluated whether there was a difference between the tutored group and automated training program in terms of letter recognition and fluency. We will present our results and discuss pros and cons of in-person vs. automated instruction in reading acquisition as well as implications for future research.

Meaning in Life is Associated with Greater Exercise Behavior

Type: Undergraduate
Author(s): Karen Ji Psychology Scotty Giberson Psychology McKenna Kondratiuk Psychology Caroline Pope Psychology
Advisor(s): Cathy Cox Psychology

Nearly 70% of persons in the United States are overweight or obese. Being overweight puts people at risk for a variety of health problems, including high blood pressure, diabetes, stroke, heart disease, and heart attacks. In light of previous research demonstrating that increased meaning in life (MIL) is associated with greater well-being, the present work examined whether heightened trait and state MIL increased exercise behavior. To do this, Study 1 participants were asked to complete the Meaning in Life Questionnaire (Steger et al., 2006) to assess for individual differences in MIL; whereas, Study 2 persons were randomly assigned to a meaning manipulation (i.e., writing about an meaningful event) versus a control prompt (i.e., writing about a daily activity). Persons, in both studies, wore Fitbit activity trackers to assess steps taken over the course of 1-2 weeks. The results revealed that greater instances of MIL (either as a trait or state) were associated with a heightened engagement in Fitbit activities. The current research is thus important in identifying a low cost intervention (e.g., writing) to increase health and well-being.
