Item COMPATIBILITY IN TEAM COGNITION: MOVING BEYOND SIMILARITY(2024) Strauss, Joshua; Grand, James A; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Team cognition is a well-recognized antecedent of team processes and performance. Compatibility of mental representations is critical to many theoretical frameworks and approaches to team cognition. However, compatibility is often relegated to an unexplored assumption or assumed to be sufficiently captured by the similarity or overlap of mental representations. This paper extends the Team-Task Representation (TTR) framework proposed by Strauss (2022) to (1) define and (2) operationalize compatibility, (3) proposes a process through which compatibility relates to team processes and performance, and (4) provide empirical tests of these relationships. A study was conducted using an online, cooperative, gamified task to test the relationship between TTR compatibility and coordination and the extent to which coordination mediated the relationship between compatibility and performance. Compatibility did not predict coordination and coordination was not found to mediate the relationship between compatibility and performance. Conclusions and consequences for the field of team cognition are discussed.Item Untangling the Sea of Trees: An Architectural Analysis of the Impact of the Built Environment on Suicide Rates in Japan(2024) Richmond, Addison R.; Noonan, Peter V.; Architecture; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Resulting in over 30,000 mortalities every year, suicide ranks as the number one cause of death for young adults in Japan. Extreme stress at work, Stigma surrounding mental health, and congested urban conditions cause hundreds to see the Aokigahara Suicide Forest as their only option. With its increased notoriety as the second most visited suicide location in the world, how can we utilize biophilic design, traditional Japanese construction methods, and Zen Buddhist philosophies to reduce work stress, and prevent depression, and help individuals untangle the sea of trees?Item Statistical Learning Across Modalities, Domains and Languages(2024) Ren, Jinglei; Wang, Min; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation establishes a comprehensive line of research that systematically exploresstatistical learning (SL) across modalities, domains, and languages. The first study delves into SL development, exploring SL changes across different ages, linguistic and non-linguistic domains, visual and auditory modalities, and languages (specifically, Chinese and English). In the second study, the focus is shifted to the probabilistic regularities embedded in a specific written language. This study investigated the ability to use word endings as a probabilistic cue to lexical stress among those who acquired a second language (L2) in formal learning settings through years of practice. The third study broadens the scope further, delving into whether beginning English learners benefit from a specialized training program emphasizing the association between word endings and lexical stress. The collective body of research in this dissertation makes significant contributions to the fields of cognitive science, linguistics, and education. Ultimately, the insights gleaned have the capacity to positively impact learners of various ages and diverse backgrounds, and to offer valuable implications for educational practices.Item PSYCHOSOCIAL STRESS AND INTERNALIZING SYMPTOMS IN BLACK EMERGING ADULTS: THE ROLE OF PHYSIOLOGICAL DYSREGULATION AND CULTURAL SOCIALIZATION(2024) Wang, Yuqi; Tyrell, Fanita A; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Research suggests that ethnic-racial minority emerging adults disproportionately experience higher levels of internalizing problems due to exposure to higher levels of generalized stress (e.g., perceived stress) and unique, race-related stress (e.g., discrimination), which is especially relevant for Black emerging adults. However, few studies have examined the unique contributions of these types of stress and the mechanisms that facilitate their detrimental mental health effects. Informed by existing theoretical models, the current study evaluated the unique contribution of both generalized and discriminatory stress on internalizing symptoms (i.e., anxiety and depression) as well as the mediating role of physiological functioning (i.e., diurnal cortisol slope, C-reactive protein) on these associations. Further, the current study takes astrength-based approach by examining the potential protective role of cultural socialization on the links among psychosocial stress, physiological functioning, and internalizing symptoms. Findings indicate that generalized stress and discriminatory stress both contribute to depressive symptoms and physiological functioning in Black emerging adults, although the links between psychosocial stress and internalizing symptoms were not mediated by physiological functioning. In addition, cultural socialization protected or exacerbated the effects of psychosocial stress on mental and physiological health outcomes depending on the type and severity of the stressor. These findings suggest that therapeutic treatment and intervention efforts for Black emerging adults should consider the impact of both types of stress on these youth’s mental and physiological health as well as the nuanced role of cultural socialization on these links. Future research should examine how other types of psychosocial stress, mediating mechanisms, and resilience processes may impact the mental and physiological health outcomes of Black emerging adults.Item THE CROSS-LANGUAGE ACTIVATION OF FIRST LANGUAGE (L1) HOMONYMS TRANSLATIONS IN SECOND LANGUAGE (L2) PROCESSING: AN INVESTIGATION OF WHETHER L1 TRANSLATION ARE ACTIVATED IN L2 SENTENCE CONTEXT(2024) Alsalmi, Mona Othman; Jiang, Nan; Second Language Acquisition and Application; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)A present study aimed to investigate the role of a first language (L1) translation on a second language (L2) word processing in a sentential context by relatively advanced Arabic learners of English. The focus is on cases where a homonymous word in the L1 is realized by independent words in the L2, (e.g. Arabic قرش realized by English shark and coin). Using the visual-world paradigm, Arabic-English bilinguals and English native participants were auditorily presented with English sentences that are predictive of a target word (e.g., “shark” in Scuba divers saw the sharp teeth of a giant shark yesterday) while looking at a visual screen. The screen contained one of the three critical objects: a target object whose English name corresponded to the target word (shark; Arabic: قرش) in the target condition, an Arabic competitor object whose Arabic name shared the same Arabic translation with the target word (coin; Arabic: قرش) in the Arabic condition, or an object that was unrelated to the target word (drums; Arabic طبل) in the control condition.Compared to native speakers of English, relatively advanced Saudi learners of English made more fixations on the critical objects in the Arabic condition compared to the control condition. This study supports the potential automatic activation of L1 translations when processing sentences in L2, even in relatively proficient learners and suggests evidence for the verification model in L2 word recognition.Item Examining pre-training interpersonal skills as a predictor of post-training competence in mental health care among lay health workers in South Africa(2023) Rose, Alexandra Leah; Magidson, Jessica F.; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)A worldwide shortage of mental health specialists contributes to a substantial global mental health treatment gap. Despite evidence that lay health workers (LHWs), or health workers with little formal training, can effectively deliver mental health care, LHWs vary widely in their abilities to competently deliver mental health care, which undermines the quality of care and patient safety. Prior research from both high-income and low- and middle-income countries suggests this variability may be predicted by LHW interpersonal skills, yet this relationship is little explored to date. The first aim of the current study, which uses an exploratory sequential mixed methods design, was to explore qualitative perspectives through semi-structured individual interviews (n=20, researchers, policymakers, NGO staff, LHWs) in Cape Town, South Africa on interpersonal skills relevant to delivery of mental health interventions by LHWs. The second aim was to quantitatively examine the preliminary effectiveness of pre-training interpersonal skills in predicting post-training competence following a mental health training among LHWs in Cape Town (n=26). Using a standardized LHW assessment measure adapted to the setting, two raters rated ten-minute standardized role plays conducted before and after the training for pre-training interpersonal skills and post-training competence. Qualitative findings highlight the perceived importance of and challenges with assessing interpersonal skills among LHWs being trained in psychological intervention. Quantitative analyses did not identify any interpersonal skills as significant predictors of post-training competence. However, interpersonal skills improved during the training itself, specifically verbal communication, suggesting the potential promise of further research in this area. Recruitment of larger samples with more variable training outcomes would be important in future studies examining predictors of LHW competence. Further research may ultimately help identify areas of intervention to support more LHWs in attaining competence and can help play an important role in increasing access to psychological services globally.Item Decolonizing in Individual Psychotherapy: A Qualitative Exploration(2024) Bansal, Priya; Hill, Clara E; Counseling and Personnel Services; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)We interviewed 12 therapists experienced in practicing decolonizing about their understanding of decolonizing and its relevance to therapy, as well as how they implemented this approach with at least one client. Interviews were analyzed using Consensual Qualitative Research (CQR) and revealed that colonial paradigms had negative individual, relational, and societal impacts; therapists used a range of interventions aligned with decolonizing, including interventions to help clients gain insight about the systemic context of psychological problems and to facilitate client resistance of colonial ideologies; sociocultural identity interactions between therapist and client considerably shaped the therapy work; therapists encountered conceptual, practical, and systemic barriers to decolonizing practice; and clients experienced improvements across intrapersonal and interpersonal functioning. Implications for practice and research are discussed.Item Predictors of Peer Interaction Success for Autistic and Non-Autistic Youth(2024) McNaughton, Kathryn; Redcay, Elizabeth; Neuroscience and Cognitive Science; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Successful peer interactions are a crucial component of mental health and well-being for autistic and non-autistic youth. Factors that influence successful peer interactions are particularly relevant to investigate in middle childhood and adolescence, a developmental period in which peer interactions take on increased importance for mental health. Research into social interactions can involve both individual-level and interindividual-level understanding of interaction outcomes. Individual-level predictors can yield insight into the way one’s own characteristics predict social interaction outcomes, for example, informing theories about how an individual’s social motivation may predict their social enjoyment. However, because research into social interaction challenges and success in autism has historically focused on individual-level contributions of autistic individuals to social interaction outcomes, it is also important to understand interindividual-level mechanisms, such as the similarity or synchrony between individuals, to understand the role both non-autistic and autistic individuals play in shaping social interactions and their outcomes. Therefore, the overarching goal of this dissertation is to evaluate potential neural and behavioral predictors of peer interaction success in autistic and non-autistic youth during middle childhood and adolescence at the individual and interindividual level. First, I demonstrate that neural sensitivity to social-interactive reward is an individual-level predictor of peer interaction enjoyment. Next, I move beyond individual-level neural predictors to interindividual-level neural predictors, providing evidence for how neural similarity to peers may differentially relate to day-to-day interaction success across different interaction types, such as interactions with peers. Finally, I establish smiling synchronization as an interindividual predictor of peer interaction enjoyment. These studies span the neural and behavioral levels of analysis, providing insight into how these levels of analysis can be investigated from both an individual and interindividual perspective. The findings advance understanding of factors that predict peer interaction success, leading to better understanding of opportunities to support successful peer interactions through individual and interindividual interventions with autistic and non-autistic youth.Item Early adolescent romantic experiences and psychosocial functioning in sexual minority youth(2023) Hubachek, Samantha Qirko; Dougherty, Lea R; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Sexual minority youth are at greater risk for negative psychosocial outcomes starting in early adolescence, in part due to stress related to stigma and discrimination. We examined early adolescent romantic involvement as a potential risk or protective factor for the development of psychosocial concerns in sexual minority youth using two independent samples of youth assessed in early adolescence. Study 1 utilized prospective, longitudinal data from the Stony Brook Temperament Study (SBTS) to examine associations between youth romantic experiences, sexual orientation, and psychosocial functioning from early (age 12) to middle (age 15) adolescence (N=392; n=348 heterosexual youth, n=44 sexual minority youth). Study 2 utilized cross-sectional data from the Adolescent Brain Cognitive Development (ABCD) Study, a study with a larger and more diverse sample, to further examine the interaction between romantic experiences and sexual orientation in association with psychiatric symptoms in early adolescence (age 12), as well as whether interactive effects of romantic experiences and sexual orientation on psychiatric symptoms vary based on race/ethnicity or socioeconomic status (N=7184; n=6633 heterosexual youth, n=551 sexual minority youth). Although heterosexual and sexual minority youth were equally likely to have romantic and sexual experience in the SBTS sample, sexual minority youth were more likely to participate in romantic and sexual activity in early adolescence than their heterosexual peers in the ABCD sample. Across both samples, romantic experience in early adolescence was associated with poorer concurrent and subsequent psychosocial outcomes for sexual minority youth. Further, the interactive effects of romantic experience and sexual orientation in association with psychosocial outcomes did not vary based on race/ethnicity or parental education in the ABCD sample. These findings begin to characterize early adolescent romantic experiences in sexual minority youth and suggest that romantic involvement during this period may be linked to psychosocial concerns. This work may inform future clinical interventions targeting mental health in sexual minority youth.Item PREDICTING PSYCHOLOGICAL ADJUSTMENT IN GRIEF: CROSS-NATIONAL DIFFERENCES AMONG KOREANS AND AMERICANS(2023) Yang, NaYeon; O'Brien, Karen M.; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Grieving the death of a significant individual is a universal experience. However, the rituals, beliefs, and meanings surrounding death are shaped by one’s cultural values. Recent scholars stressed the importance of recognizing cultural differences in bereavement, as Western-centric perspectives on grief in the bereavement literature could adversely affect clients with different cultural backgrounds (Rosenblatt, 2008). Prior research demonstrated that the constructs contributing to healthy grieving may differ across cultures. Specifically, continuing bonds, meaning-making, and social support have been identified as three constructs associated with bereaved individuals’ psychological adjustment in several cultures (e.g., Gillies et al., 2015; Kim et al., 2008; Scholtes & Browne, 2015; Yang & Lee, 2020). Thus, the purpose of the present study was to examine the similarities and differences in the relations among psychological distress, salient grief-related variables (i.e., internalized/externalized continuing bonds, meaning-making, and implicit/explicit social support), and psychological adjustment among Koreans and Americans during their grieving process. The data were collected in the United States and South Korea. The results indicated that psychological distress and one subscale of meaning-making (i.e., emptiness and meaninglessness) were associated with psychological adjustment for both US and Korean bereaved individuals. For US bereaved individuals, externalized continuing bonds and one subscale of meaning-making (i.e., being present) were positively associated with psychological adjustment, whereas one subscale of meaning-making (i.e., sense of peace) was negatively associated with psychological adjustment. For Korean individuals, implicit social support was positively associated with psychological adjustment. Overall, the results indicated that there may be both universal and culturally unique aspects of grieving. Clinical implications and future research considerations are discussed.
