Publication Metadata only Development and preliminary validation of the PrEP empowerment scale(Springer/Plenum Publishers, 2023) Crockett, Kaylee B.; Batey, D. Scott; Department of Psychology; Turan, Bülent; Department of Psychology; College of Social Sciences and HumanitiesInformed by the Health Care Empowerment Model, a measure of PrEP Empowerment was developed and assessed for preliminary reliability and validity. Participants (N = 100) were invited to complete a survey during regular clinic visits. A subset (n = 84) volunteered to provide blood samples to assess plasma tenofovir (TFV) levels for recent PrEP adherence. A five-factor measure explained 70% of the total variance. Associations with internalized PrEP stigma, PrEP adherence self-efficacy, and plasma TFV were assessed. Results supported the multidimensional nature of PrEP Empowerment and reliability and validity. Additional research is needed in populations with varying PrEP experience and greater gender and ethnic representation.Publication Metadata only The relationship between HIV pre-exposure prophylaxis stigma and treatment adherence among current HIV pre-exposure prophylaxis users in the Southeastern US(Springer, 2023) Van Gerwen, Olivia T.; Yigit, Ibrahim; Crockett, Kaylee B.; Department of Psychology; Turan, Bülent; Department of Psychology; College of Social Sciences and HumanitiesDespite efficacy in HIV prevention, Pre-exposure Prophylaxis (PrEP) is underutilized in the US, especially among populations at highest risk. PrEP-related stigma may play a role. We developed measures of PrEP-related stigma dimensions and PrEP adherence. We administered them to current PrEP users. We hypothesized that PrEP-related stigma would negatively impact PrEP adherence. Questionnaire measures were developed using data from previous qualitative work and existing validated HIV-related stigma measures. The resultant survey was administered to current PrEP users from two Birmingham, Alabama PrEP clinics. Plasma tenofovir disoproxil fumarate levels were collected to measure PrEP adherence. Exploratory factor analyses were performed to determine the factor structure of each PrEP-related stigma dimension (internalized, perceived, experienced, anticipated, disclosure concerns). Separate binary logistic (or linear) regressions were performed to assess associations between PrEP-related stigma dimensions and adherence (treatment adherence self-efficacy, self-reported adherence, and plasma tenofovir levels), adjusting for education, race, and time on PrEP. In 2018, 100 participants completed the survey, with 91 identifying as male and 66 as white. Only internalized stigma was associated with lower self-reported PrEP adherence. Exploratory mediation analyses suggested that the association between all stigma dimensions and self-reported PrEP adherence is mediated by PrEP adherence self-efficacy. No associations were found between any PrEP-related stigma measures and plasma tenofovir levels. Internalized PrEP stigma may reduce PrEP adherence, possibly by reducing PrEP adherence self-efficacy among experienced PrEP users. Further investigation of how stigma dimensions affect PrEP adherence in populations at risk for HIV may shed light on drivers of PrEP underutilization.Publication Metadata only Vertical individualism orientations and mental health stigma: the mediating role of belief in free will(Springer, 2023) Ozkok, Hazal; Altan-Atalay, Ayse; Department of Psychology; Turan, Bülent; Özkök, Maide Hazal; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and HumanitiesEven though the stigma related to mental health is widespread, stigma related to suicide and substance use are less researched areas. This study investigates whether belief in free will mediates the association between vertical individualism and stigma against those who use substances or attempt suicide. Turkish adult participants (n = 200, M-age = 29.8, SD = 11.9) completed self-report measures of cultural orientation, belief in free will, substance use stigma, and suicide stigma. Results revealed that individuals' belief in free will mediates the association of vertical individualism with both suicide and substance use stigma. This suggests that free will belief may be one of the ways in which cultural orientations are linked to stigma. These results can contribute to the design of sophisticated stigma reduction interventions that take into account belief in free will and cultural orientation.Publication Metadata only The role of social support on cognitive function among midlife and older adult MSM(Lippincott Williams & Wilkins, 2023) Henderson, Emmett R.; Haberlen, Sabina A.; Coulter, Robert W. S.; Weinstein, Andrea M.; Meanley, Steven; Brennan-Ing, Mark; Mimiaga, Matthew J.; Turan, Janet M.; Teplin, Linda A.; Egan, James E.; Plankey, Michael W.; Friedman, M. Reuel; Department of Psychology; Turan, Bülent; Department of Psychology; College of Social Sciences and HumanitiesObjective:This study examines the association between social support and cognitive function among midlife and older MSM living with or without HIV.Design:We analyzed longitudinal data from participants enrolled from October 2016 to March 2019 in the Patterns of Healthy Aging Study, a substudy of the Multicenter AIDS Cohort Study. Methods: We conducted a cross-sectional analysis to estimate the association between social support and three measures of cognitive function [Trail Making Test (TMT) Part A, TMT Part B to A ratio, and Symbol Digit Modalities Tasks (SDMT)]. We also used linear mixed-effects models to estimate the association between baseline social support and cognitive function across four subsequent time points. We evaluated a multiplicative interaction term between baseline social support and time, in order to determine whether cognitive trajectories over time vary by baseline social support. Results: Social support was associated with lower TMT Part A scores at baseline and over the subsequent 2 years, indicating better psychomotor ability. Social support was associated with higher SDMT scores at baseline and across 2 years, indicating better information processing. We observed no association between social support and TMT B to A ratio at baseline or across 2 years, indicating no effect on set-shifting ability. Longitudinal cognition outcome trajectories did not vary by the level of baseline social support. Conclusion: Social support and cognitive function were associated in this sample over a short time period. Further research should explore causal relationships over the lifespan.Publication Metadata only Does source reliability moderate the survival processing effect? The role of linguistic markers as reliability cues(Springer, 2024) Department of Psychology; Göksun, Tilbe; Akçay, Çağlar; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and HumanitiesAdaptive memory retains information that would increase survival chances and reproductive success, resulting in the survival processing effect. Less is known about whether the reliability of the information interacts with the survival processing effect. From an adaptive point, information from reliable sources should lead to better encoding of information, particularly in a survival context. In Turkish, specific linguistic components called evidentiality markers encode whether the information presented is firsthand (direct) or not (indirect), providing insight into source reliability. In two experiments, we examined the effect of evidentiality markers on recall across survival and nonsurvival (moving) contexts, predicting that the survival processing effect would be stronger for information marked with evidentiality markers indicating direct information. Results of both experiments yielded a robust survival processing effect, as the sentences processed for their relevance to survival were better remembered than those processed for their relevance to nonsurvival events. Yet the marker type did not affect retention, regardless of being tested as a between- or within-subject factor. Specifically, the survival processing effect persisted even with evidentiality markers indicating indirect information, which suggests that the processing of survival-related information may be privileged even if potentially unreliable. We discuss these results in the context of recent studies of the interaction of language with memory.Publication Metadata only Influences of early and intense L2 exposure on L1 causal verb production: comparison of 5-, 7-, and 9-year-old bilingual and monolingual children(SAGE Publications, 2024) Aktan-Erciyes, Asli; Ger, Ebru; Department of Psychology; Göksun, Tilbe; Department of Psychology; College of Social Sciences and HumanitiesThis study investigates the influences of early and intense L2 exposure on children's L1 causative verb production, assessed by an experimental causative verb production task. Turkish expresses causality by morphological and lexical means, whereas English does so by periphrastic and lexical means. Learning L2 English might enhance L1 Turkish causative verb production by highlighting the parallels and contrasts in causal expressions between the languages, which may result in an enriched L1 causative use. Five-, 7 -, and 9-year-old L1-Turkish L2-English bilingual (n = 80) and L1-Turkish monolingual (n = 80) children participated in the study in L1-Turkish. Results indicated that language group differences only emerged for the use of morphological causative verbs in favor of 5-year-old bilinguals compared with monolingual peers. Age group differences occurred only for the monolingual group and only for morphological verbs. Specifically, monolingual 7- and 9-year-olds performed better than monolingual 5-year-olds. Causative verb-type differences were only seen for 5-year-old monolinguals, who performed better for lexical than morphological verbs; in contrast, 5-year-old bilinguals performed equally well on the two types of causatives, and better than 5-year-old monolinguals on morphological causatives. Overall, these findings indicate that learning an L2 with structural similarities and differences compared with L1 might enhance children's awareness and correct use of causal linguistic structures.Publication Metadata only Give your ideas a hand: the role of iconic hand gestures in enhancing divergent creative thinking(Springer Science and Business Media Deutschland GmbH, 2024) Department of Psychology; Hyusein, Gyulten Shaban; Göksun, Tilbe; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and HumanitiesHand gestures play an integral role in multimodal language and communication. Even though the self-oriented functions of gestures, such as activating a speaker's lexicon and maintaining visuospatial imagery, have been emphasized, gestures' functions in creative thinking are not well-established. In the current study, we investigated the role of iconic gestures in verbal divergent thinking-a creative thinking process related to generating many novel ideas. Based on previous findings, we hypothesized that iconic gesture use would facilitate divergent thinking in young adults, especially those with high mental imagery skills. Participants performed Guildford's Alternative Uses Task in a gesture-spontaneous and in a gesture-encouraged condition. We measured fluency (number of ideas), originality (uniqueness of ideas), flexibility (number of idea categories), and elaboration (number of details) in divergent thinking. The results showed that producing iconic gestures in the gesture-encouraged condition positively predicted fluency, originality, and elaboration. In the gesture-spontaneous condition, producing iconic gestures also positively predicted elaboration but negatively predicted flexibility. Mental imagery skills did not interact with the effects of gestures on divergent thinking. These results suggest that iconic gestures are a promising candidate for enhancing almost all aspects of divergent thinking. Overall, the current study adds a new dimension to the self-oriented function of iconic gestures, that is, their contribution to creative thinking.Publication Metadata only Altered temporal awareness during covid-19 pandemic(Springer Science and Business Media Deutschland GmbH, 2024) van Wassenhove, Virginie; Department of Psychology; Runyun, Şerife Leman; Balcı, Fuat; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and HumanitiesSocial isolation during the COVID-19 pandemic had profound effects on human well-being. A handful of studies have focused on how time perception was altered during the COVID-19 pandemic, while no study has tested whether temporal metacognition is also affected by the lockdown. We examined the impact of long-term social isolation during the COVID-19 pandemic on the ability to monitor errors in timing performance. We recruited 1232 participants from 12 countries during lockdown, 211 of which were retested "post-pandemic" for within-group comparisons. We also tested a new group of 331 participants during the "post-pandemic" period and compared their data to those of 1232 participants tested during the lockdown (between-group comparison). Participants produced a 3600 ms target interval and assessed the magnitude and direction of their time production error. Both within and between-group comparisons showed reduced metric error monitoring performance during the lockdown, even after controlling for government-imposed stringency indices. A higher level of reported social isolation also predicted reduced temporal error monitoring ability. Participants produced longer duration during lockdown compared to post-lockdown (again controlling for government stringency indices). We reason that these effects may be underlain by altered biological and behavioral rhythms during social isolation experienced during the COVID-19 pandemic. Understanding these effects is crucial for a more complete characterization of the cognitive consequences of long-term social isolation.Publication Metadata only Understanding patterns of accumulation: improving forecast-based decisions via nudging(Springer, 2024) Boz-Yilmaz, Hatice Zulal; Department of Psychology; Gököz, Zeynep Ayşecan Boduroğlu; Department of Psychology; College of Social Sciences and HumanitiesIn this study we investigated challenges associated with comprehension of graphical patterns of accumulation (Experiment 1) and how to improve accumulation-based reasoning via nudging (Experiment 2). On each trial participants were presented with two separate graphs, each depicting a linear, saturating, or exponential data trajectory. They were then asked to make a binary decision based on their forecasts of how these trends would evolve. Correct responses were associated with a focus on the rate of increase in graphs; incorrect responses were driven by prior knowledge and beliefs regarding the context and/or selective attention towards the early phases of the line trajectories. To encourage participants to think more critically and accurately about the presented data, in Experiment 2, participants completed a nudge phase: they either made a forecast about a near horizon or read particular values on the studied trajectories prior to making their decisions. Forecasting about how the studied trajectories would progress led to improvements in determining expected accumulation growth. Merely reading values on the existing trajectory did not lead to improvements in decision accuracy. We demonstrate that actively asking participants to make specific forecasts prior to making decisions based on the accumulation trajectories improves decision accuracy.Publication Metadata only The role of culture and semantic organization in working memory updating(Routledge Journals, Taylor and Francis Ltd, 2024) Leger, Krystal R.; Snyder, Hannah R.; Gutchess, Angela; Department of Psychology; Gököz, Zeynep Ayşecan Boduroğlu; Department of Psychology; College of Social Sciences and HumanitiesWesterners tend to relate items in a categorical manner, whereas Easterners focus more on functional relationships. The present study extended research on semantic organization in long-term memory to working memory. First, Americans' and Turks' preferences for categorical versus functional relationships were tested. Second, working memory interference was assessed using a 2-back working memory paradigm in which lure items were categorically and functionally related to targets. Next, a mediation model tested direct effects of culture and semantic organization on working memory task behaviour, and the indirect effect, whether semantic organization mediated the relationship between culture and working memory interference. Whereas Americans had slower response times to correctly rejecting functional lures compared to categorical lures, conditions did not differ for Turks. However, semantic organization did not mediate cultural difference in working memory interference. Across cultures, there was evidence that semantic organization affected working memory errors, with individuals who endorsed categorical more than functional pairings committing more categorical than functional errors on the 2-back task. Results align with prior research suggesting individual differences in use of different types of semantic relationships, and further that literature by indicating effects on interference in working memory. However, these individual differences may not be culture-dependent.
