Impulsivity And Brain Organization In Childhood Suicide: An Adolescent Brain And Cognitive Development (Abcd) Study, Katherine Lopez
Impulsivity And Brain Organization In Childhood Suicide: An Adolescent Brain And Cognitive Development (Abcd) Study, Katherine Lopez
Arts & Sciences Electronic Theses and Dissertations
Rates of suicide have steadily increased across all age cohorts, revealing a particularly concerning rise in suicide among much younger age groups (10-15 years old). Recent efforts aimed at understanding suicide in youth have leveraged work from the adult literature to more pointedly examine candidate risk factors associated with childhood suicide. A noteworthy body of work has begun to clarify the role that impulsivity plays in elevating suicide risk among adults and adolescents, a critical link warranting further research in childhood suicide given the vast and well-documented changes occurring in self-control and brain maturity throughout development. Here, we examined a …
Selection Or Socialization? A Propensity Score Matched Study Of Personality And Life Events, Emorie Beck
Selection Or Socialization? A Propensity Score Matched Study Of Personality And Life Events, Emorie Beck
Arts & Sciences Electronic Theses and Dissertations
Across the lifespan, personality changes in normative ways, but the source of such change remains ambiguous. Life events may be one impetus of such change, but strong selection effects into such events makes it unclear whether such change is driven by already existing differences (selection) between people or socialization following life events. In a preregistered study, we test socialization and selection effects of the Big 5 and life events using a large (N = 19,627) representative sample of Germans and 12 life events (e.g. marriage, retirement) from the GSOEP. Using propensity score matching and Bayesian multilevel growth curve models, we …
Development Of Social Exclusion Detection: Behavioral And Physiological Correlates, Hyesung Grace Hwang
Development Of Social Exclusion Detection: Behavioral And Physiological Correlates, Hyesung Grace Hwang
Arts & Sciences Electronic Theses and Dissertations
The present work aimed to directly test the theoretical claims about how we as human detect social exclusion using both physiological and behavioral methods across different life stages. Because feeling excluded from a group is a common human experience that starts in early childhood, this basic human need to belong or connect with others is argued to be universal and thought to have an evolutionary basis. In fact, it has been argued that the ability to detect being excluded may be present from birth and detecting exclusion occurs rapidly with little cognitive processing. Study 1 tested whether this rapid detection …
Developmental Trajectories Of Executive And Verbal Processes In Children With Phenylketonuria, Zoe Hawks
Developmental Trajectories Of Executive And Verbal Processes In Children With Phenylketonuria, Zoe Hawks
Arts & Sciences Electronic Theses and Dissertations
Phenylketonuria (PKU) is a recessive disorder characterized by disruption in the metabolism of the amino acid phenylalanine. Using a verbal fluency task, previous studies demonstrated that word production is reduced in individuals with PKU relative to controls. Beyond word production, verbal fluency output can be scored for clustering and switching, which enable characterization of verbal and executive processes, respectively. The present study is the first to evaluate clustering and switching in PKU within a longitudinal design, thereby elucidating the developmental time course of core cognitive processes. To this end, semantic (animals, food/drink) and phonemic (S words, F words) fluency data …
