Anecdotally, native Mandarin speakers have difficulty distinguishing between the “s” (as in sink) and the “th” (as in think) sounds as well as between the “a” (as in dad) and “ea” (as in dead) sounds. Here, 29 native English speakers, 52 native Mandarin speakers who live in China, and 34

Anecdotally, native Mandarin speakers have difficulty distinguishing between the “s” (as in sink) and the “th” (as in think) sounds as well as between the “a” (as in dad) and “ea” (as in dead) sounds. Here, 29 native English speakers, 52 native Mandarin speakers who live in China, and 34 native Mandarin speakers who have been living in an English language dominant environment were recruited to serve as participants. To assess the phoneme contrasts that may occur in native Mandarin speakers in China, and possible improvement in native Mandarin speakers living in an English environment, relative to Native English speakers living in America, a phoneme discrimination test was administered, three paired phonemes were used in the current study: /b/ paired with /p/ as a control pair, /æ/ paired with /ɛ/, and /θ/ paired with /s/. The results showed that native English speakers have significantly higher accuracy rates for the three paired phoneme discrimination tasks than the native Mandarin speakers who live in China. But there was no significant difference between the native English speakers and native Mandarin speakers who have lived in an English environment on the phonemes or words discriminations tasks.

This study aimed to develop a measurement model for executive function (EF) in middle childhood for a low-income Mexican American sample and to elucidate dynamic change processes among measurable developmental correlates of EF during infancy and early toddlerhood as predictors of later higher-order EF abilities. Drawing from developmental theory and a model of neurovisceral integration, surges in neurocognitive regulatory abilities may be supported by both previous and concurrent changes in physiological functioning and engagement in reciprocal social relationships. Utilizing recent methodological innovations, the current study moved beyond traditional growth models to evaluate possible points of attenuation and acceleration in dyadic reciprocity and vagal functioning over time as well as dynamic associations between these unfolding developmental processes. Data were collected from 322 low-income Mexican American children in the home at 24 weeks and in a laboratory space at ages 1, 1.5, 2, 3, and 6 years. A parent-report measure of executive function also was collected over the phone between child age 7.5 and 9 years. Results suggested that, in this sample, EF was best modeled at child age 6 years as a unidimensional construct. Findings also supported the importance of earlier dyadic reciprocity for later EF, but there was a lack of evidence supporting the theorized link between EF and earlier vagal functioning and codevelopment of vagal functioning and dyadic reciprocity. This study highlights the importance of including dyadic measures of parent-child contingencies in studies of EF development and, from a clinical perspective, the potential use of relationship-based, dyadic intervention and prevention models to support crucial development of EF skills central to everyday adaptive functioning.

In the legal system, the prediction of a person’s risk of committing a crime has mostly been based on expert judgment. However, newer techniques that employ machine learning (ML)—a type of artificial intelligence—are being implemented throughout the justice system. Yet, there is a lack of research on how the public perceives and uses machine learning risk assessments in legal settings. In two mock-trial vignette studies, the perception of ML-based risk assessments versus more traditional methods was assessed. Study 1 was a 2 (severity of crime: low, high) x 2 (risk assessment type: expert, machine learning) x 2 (risk outcome: low, high) between-subjects design. Participants expressed ethical concerns and discouraged the use of machine learning risk assessments in sentencing decisions, but punishment recommendations were not affected. Study 2 was a within-subjects design where participants were randomly assigned read through one of three crime scenarios (violent, white-collar, sex offense) and one of three risk assessment techniques (expert, checklist, machine learning). Consistent with Study 1, participants had ethical concerns and disagreed with the use of machine learning risk assessments in bail decisions, yet their own decisions and recommendations did not reflect these concerns. Overall, laypeople express skepticism toward these new methods, but do not appear to differentially rely on ML-based versus traditional risk assessments in their own judgments.

Concussion, or mild traumatic brain injury (mTBI), is a frequent cause of brain damage among youth and, therefore, represents a major public health problem. While most youth recover from concussion within 2 to 4 weeks, some concussed children and adolescents endure prolonged symptoms, along with mood disturbance sequelae for months. Few studies have assessed mood disturbance and concussion in pediatric populations. Additional research is necessary to understand pediatric concussion recovery and mood disturbance better, to guide early intervention efforts, and to improve pediatric concussion care. The purpose of this study was to examine how symptoms of mood disturbance (i.e., anxiety, depression, anger) and somatization relate to the odds of concussion recovery in male and female youth 12 to 17 years of age, who presented for neuropsychological evaluation after head injury. Significantly fewer females were deemed recovered at initial neuropsychological evaluation compared to males. Bivariate analyses of mood disturbance and somatization predictors revealed significant group differences in symptom burden between those determined recovered from concussion and those who had not recovered. Logistic regressions of each mood disturbance variable and somatization on concussion recovery suggested a modest decline in the odds of recovery as symptoms of mood disturbance or somatization increase. A multivariable logistic regression model of mood disturbance predictors, somatization, gender, and age was significant and explained over a quarter of the variance in concussion recovery; however, after a backward variable selection procedure, only depression and somatization symptoms were significant in the final model and accounted for a modest decline in the odds of concussion recovery at initial evaluation. Results replicate and extend research findings in pediatric concussion.

The prevalence of autonomous technology is advancing at a rapid rate and is becoming more sophisticated. As this technology becomes more advanced, humans and autonomy may work together as teammates in various settings. A crucial component of teaming is trust, but to date, researchers are limited in assessing trust calibration dynamically in human-autonomy teams. Traditional methods of measuring trust (e.g., Likert scale questionnaires) capture trust after the fact or at a specific time. However, trust fluctuates, and determining what causes this might give machine designers insight into how machines can be improved upon so that operator’s trust towards the machines is more properly calibrated. This thesis aimed to assess the validity of an interaction-based metric of trust: anticipatory pushing of information. Anticipatory pushing of information refers to teammate A anticipating the needs of teammate B and pushing that information to teammate B. It was hypothesized there would be a positive relationship between the frequency of anticipatory pushing and self-reported trust scores. To test this hypothesis, text chat data and self-reported trust scores were analyzed in a previously conducted study in two different sessions (routine and degraded). Findings indicate that the anticipatory pushing of information and the self-reported trust scores between the human-human pairs in the degraded sessions were higher than the routine sessions. In degraded sessions, the anticipatory pushing of information between the human-human pairs was associated with human-human trust.

Individuals with psychogenic non-epileptic seizures (PNES) show signs of emotion-related dysfunction and disrupted interpersonal relationships. Affectionate touch is an important form of non-verbal communication in relationships that may foster emotion regulation and emotional awareness. The present online survey study included 62 individuals with PNES and 80 seizure-free trauma-exposed controls high (n=40) or low (n=40) in overall symptoms of psychopathology. As hypothesized, PNES individuals reported experiencing less frequent affectionate touch and less interoceptive awareness than either control group. They also reported more somatic symptoms, more emotion regulation difficulties, and less positive emotion than the low psychopathology group. Unexpectedly, there were no group differences in emotional awareness difficulties, nor in initiation of affectionate touch. Across participants, lower interoceptive awareness was associated with lower affectionate touch frequency, indicating that if one has difficulty understanding and being aware of their own body, affectionate touch sensations may not necessarily be understood as pleasant and may be minimized or avoided. Emotional awareness difficulties surprisingly were associated with greater affectionate touch frequency among PNES (versus the expected pattern of awareness difficulties associated with less affectionate touch, as found among controls), suggesting affectionate touch may be used as an attempt to try and understand one’s own feelings, or to compensate for, or even mask a lack of understanding. Findings indicate a distinct difference in physical affection frequency and interoceptive awareness among PNES individuals even when matched to a group similar in psychiatric distress/psychopathology. These findings offer insight into the relationships between interoceptive awareness, affectionate touch, and emotion regulation more broadly.

The COVID-19 pandemic has greatly impacted the structure of work foremployees worldwide, as many began working remotely in response to national and local social distancing efforts. These changes occurring amid the transition to remote working conditions led to the question of how daily stress and daily uplifts occur in this new work context. For the present thesis study, I explored how internal (i.e., optimism) and external (i.e., team flow) resources function to moderate the effects of daily hassles and uplifts on employee well-being (i.e., burnout and professional efficacy) during the COVID-19 pandemic. In a sample of 417 adults at baseline, and 266 at the follow-up, I investigated how specific resources function to protect employees experiencing occupational burnout. Additionally, I explored gender differences in these relationships. Study results demonstrated that both daily uplifts and hassles predicted burnout and professional efficacy at earlier stages of the pandemic, while at a later stage in the pandemic, the relationships between daily uplifts and burnout and daily hassles and burnout persisted, but only daily hassles were associated with professional efficacy. For males at baseline, higher scores in optimism strengthened the negative relationship between daily uplifts and burnout. Surprisingly, males with relatively low team flow in work or school settings seemed to fare better professionally with increased daily hassles. This finding indicates that males with less collaboration at work thrive as they experience increased daily stress. While these findings are specific to the COVID-19 context, they may be beneficial for companies and supervisors seeking to improve employee engagement.

Excessive drinking in adolescence is a public health issue with major consequences on both an individual and societal level. Elucidating genetic and environmental influences could be particularly informative for prevention efforts. One potential source of genetic influence is sensitivity to environmental influences. It was hypothesized that parent knowledge would interact with genetic sensitivity to the environment to indirectly reduce risk for alcohol problems through less adolescent rule breaking behavior. Participants (N=316) provided genetic data and reported their rule breaking behavior and past year frequency of heavy drinking, and participants’ custodial parents reported their perceived knowledge of their child’s activities. A novel index of genetic sensitivity to environmental influence was created using published methylation quantitative trait locus data from the frontal lobe. Study hypotheses were mostly not supported. The study results likely reflect the poor distribution of study variables and the limitations of the current study’s sensitivity gene score. The current study underscored the importance of adhering to methodological rigor and explored alternate conceptualizations and methods that future research could use to elucidate the role of inherited to sensitivity to environmental influences in adolescent drinking.

Depression has been found to be a major problem for young adults in college, with multiple studies indicating high prevalence rates for this population. College students struggling with depression suffer from various consequences, including academic impairment and suicidal ideation, with suicide being a leading cause of death for people in the typical age range for undergraduates. Grounded in cognitive behavior theory and humanistic theory, this study examined the intra and interpersonal factors related to depression among undergraduates. Specifically, the interrelations between friend social support, sense of belonging to the college, mattering to friends, hope, and depressive symptoms were explored. Sex and number of close friends were controlled for, as the literature also showed evidence of their significant relations to depression. The sample consisted of 177 undergraduates between the ages of 18 and 25 from a large southwestern university. Participants responded to an online survey. While participants represented a diverse range of ethnicities, the majority were White. Hierarchical multiple regression analyses revealed that hope and sense of belonging to the college negatively predicted depressive symptoms. Furthermore, through zero-order correlations, it was found that friend social support, sense of belonging to the college, mattering to friends, and hope were all positively correlated with each other. Implications for prevention and clinical practice include the roles that counselors, college personnel, and students play in the battle against depression.

This study was designed to contribute to the existing research on the coping behaviors, social support, and mental health outcomes in parents of children with epilepsy in the United States. A questionnaire was disseminated and administered via a web-based interface. One hundred and fifty-two participants, predominantly Caucasian, married women with more than one child under the age of eighteen completed the survey.

After controlling for demographic variables, mediational analysis revealed that perceived social support explained the relation between perceived child disability and depression and anxiety. Additionally, it partially explained the relation between perceived family burden and depression, anxiety, and stress. Further, parent perception of their child's disability and perceived family burden did not predict emotion-focused or social support coping. However, both emotion-focused and social support coping behaviors were related to reductions in depression in this sample.
