Stigma towards individuals with substance use disorder (SUD) influences social attitudes towards treatment decisions and policy support (Kennedy-Hendricks et al., 2017). Prior research has shown that using stigmatizing language, such as “substance abuser” rather than “a person with substance use disorder,” increases perceptions of personal culpability and support for punitive responses (Kelly & Westerhoff, 2010). The present study examined whether personal culpability moderates the relationship between stigmatizing language and punitive attitudes towards individuals with SUD. Community members in Tarrant County were randomly assigned to read either a vignette containing person-first or a stigmatizing language and completed a brief survey online. We hypothesize that the effect of language condition on punitive attitudes will be stronger among participants with higher levels of personal culpability, such that stigmatizing language will be most strongly associated with punitive attitudes when perceived culpability is high. These findings would suggest that educational efforts aimed at reducing perceived personal culpability, particularly around the development of SUD, should be implemented to decrease punitive attitudes toward this population.

Frustrative nonreward occurs when a reward is unexpectedly reduced or omitted, producing a temporary suppression of behavior. In animals, this phenomenon is commonly studied using the consummatory successive negative contrast (cSNC) task, in which a high-value reward is replaced with a lower-value one. Following this downshift, animals typically show a reduction in consummatory behavior followed by gradual recovery as they adjust to the new reward conditions. Although the behavioral dynamics of recovery have been well described, the neural mechanisms that regulate this process remain incompletely understood. Previous research suggests that subcortical structures such as the basolateral amygdala and the nucleus accumbens play a role in the recovery of behavior after an unexpected reward downshift. However, cortical regions involved in behavioral flexibility may also contribute to recovery. The infralimbic cortex (IL), a region of the medial prefrontal cortex, has been implicated in processes such as fear extinction learning and habit regulation, both of which require updating previously learned associations and suppressing outdated responses. Based on this evidence, the present study examined whether inhibiting the IL would alter behavioral recovery following reward downshift. Rats were trained in a cSNC task in which a high-concentration sucrose solution was later downshifted to a lower concentration (32% → 2% sucrose). Animals received an infusion of inhibitory DREADDs (designer receptors exclusively activated by designer drugs) targeting the IL. Three experimental groups were tested: animals expressing inhibitory DREADDs and treated with the activating drug CNO (clozapine N-oxide), animals expressing inhibitory DREADDs but treated with a vehicle injection, and animals treated with a control infusion that has the same elements but lacks the engineered receptor and treated with CNO. Lick frequency served as the primary behavioral measure. Contrary to our initial prediction, results suggest that inhibition of the IL may accelerate behavioral recovery following reward downshift. One possible explanation for this unexpected effect is the spread of viral expression into adjacent regions, particularly the prelimbic cortex (also part of the medial prefrontal cortex), which has been associated with behavioral effects opposite to those attributed to the IL. Because the IL cortex is relatively small and anatomically close to neighboring cortical regions, DREADD diffusion may influence the functional outcome of the manipulation. These findings highlight the potential role of medial prefrontal cortex circuits in regulating behavioral adjustments to reward downshifts.

Research suggests that demographic characteristics, particularly age, significantly shape perceptions of crime and sentencing outcomes (Gleadell, 2019). Studies indicate a notable disparity in punitive leanings: younger adults tend to recommend harsher measures, whereas older adults often favor more lenient punishments (Hosch et al., 2011). This divergence may be driven by age-related increases in empathy, which can temper retributive impulses (Beadle & Vega, 2019), or by younger individuals’ limited experience with the legal system, which may hinder their ability to assess proportional sentencing (Hosch et al., 2011). Despite judicial instructions to remain objective, sentencing decisions frequently reflect these preexisting beliefs and personal experiences (Curley et al., 2022). To further explore this relationship, the current study examines how age influences perceptions of crime severity. Community members of Tarrant county were asked to read a vignette describing a low-level, nonviolent offense and rated its seriousness on a 5-point Likert scale. It is hypothesized that younger participants will perceive the offense as significantly more severe than older participants. By highlighting these generational differences, this research aims to better understand how age-related biases influence legal decision-making and inform broader discussions on legislative reform.

The ability to recall information through associations plays a crucial role across the lifespan, and is particularly important in learning health-related information. However, substantial evidence has revealed age-related declines in paired-associate learning, which involves remembering a connection between two items (Naveh-Benjamin et al., 2007). Older adults (defined here as aged 60+) often take multiple prescription medications, many of which can pose significant health risks when combined with other drugs or substances (Qato et al., 2008). Age-related memory loss can make remembering those connections more difficult. Research in the science of learning has shown that retrieval practice can significantly enhance long-term memory compared to passive strategies like rereading (Agarwal et al., 2021). As such, improving older adults’ ability to remember drug interactions through the use of retrieval practice represents a meaningful and practical goal.

To examine whether retrieval practice can improve associative memory for drug interactions, we presented both young and older adult participants with 8 fictitious medications (e.g. Floragin) and an associated interaction and outcome (diarrhea when used with alcohol). All participants studied the drugs with their corresponding substance interaction and side effects. Each participant completed 5 study blocks, with participants in the restudy condition simply rereading each medication, while those in the structured retrieval practice (SRP) condition took a practice test with immediate feedback. All participants were given an immediate test and asked to recall the interacting substance and outcome when given the medication name. Two days later, participants from both conditions completed an identical delayed test.

We hypothesized that those in the SRP condition will successfully recall more medication-interaction and outcome pairs than the restudy condition, even after the 2-day delay. We also hypothesized that the younger adults will display better recall than the older adults. Interim analyses revealed that participants who engaged in SRP demonstrated better recall compared to those in the restudy condition, regardless of age group. Critically, this outcome reveals that retrieval practice is an effective strategy for learning medication interactions. Data collection for the older adult sample is ongoing, so the lack of interaction between condition and age group should be considered preliminary

HIV-related stigma remains a significant obstacle in the prevention and delivery of care within faith-based communities. Faith communities, particularly churches in the southern United States, play a powerful role in shaping community norms and can either reinforce silence around HIV or serve as trusted entities that promote awareness and education (Pichon et al., 2020). The current study explores how individuals within religious communities perceive HIV prevention strategies and HIV-related stigma, with particular attention to how personal religiosity, church involvement, and trust in faith institutions shape attitudes toward prevention and care. Participants complete an online survey via Qualtrics covering HIV knowledge, PrEP self-efficacy, and religious trust. Recruitment will utilize flyers and raffle incentives to gather data. The study is expected to reveal both barriers and opportunities within faith-based settings, such as levels of knowledge, attitudes toward prevention strategies, and the potential role of churches in reducing stigma and partnering with health organizations. By generating community-specific insights this research can inform future public health programs, reduce stigma, and strengthen vital partnerships between healthcare providers and faith-based organizations.
