A Longitudinal Investigation of Cognitive Self-schemas across Adolescent Development

Research in developmental psychology highlights youth’s self-schemas as one possible pathway to improve adolescents’ functioning and promote positive developmental outcomes. Despite this, the trajectory of positive and negative self-schemas is relatively understudied. This study addresses this limitation by empirically examining the trajectory of self-schemas in a community sample of 623 youth (M?=?13.04 years; 54% female; 49% African American, 4% Biracial, 47% European American) who were followed over a seven-year period. Caregivers completed measures of parenting practices, maternal rumination and negative inferential style, and adolescents completed a computerized behavioral task assessing self-schemas (i.e., mental frameworks that guide attention, interpretation, and memory of one’s experiences). Multilevel growth curve modeling results demonstrated a quadratic slope for negative self-schemas and no mean-level change for positive self-schemas. These trajectories did not vary by gender or racial group. However, parenting factors differentially influenced the trajectories. Specifically, higher levels of parental involvement at baseline, or an active interest and engagement in a child’s experiences and activities, related to lower levels of negative self-schemas during adolescence. Additionally, higher levels of parental rumination and parental negative control at baseline related to lower levels of youth positive self-schemas at baseline. These findings contribute to models of youth cognitive development.

     

Cognitive Vulnerabilities Amplify the Effect of Early Pubertal Timing on Interpersonal Stress Generation During Adolescence

Early pubertal timing has been found to confer risk for the occurrence of interpersonal stressful events during adolescence. However, pre-existing vulnerabilities may exacerbate the effects of early pubertal timing on the occurrence of stressors. Thus, the current study prospectively examined whether cognitive vulnerabilities amplified the effects of early pubertal timing on interpersonal stress generation. In a diverse sample of 310 adolescents (M age = 12.83 years, 55 % female; 53 % African American), early pubertal timing predicted higher levels of interpersonal dependent events among adolescents with more negative cognitive style and rumination, but not among adolescents with lower levels of these cognitive vulnerabilities. These findings suggest that cognitive vulnerabilities may heighten the risk of generating interpersonal stress for adolescents who undergo early pubertal maturation, which may subsequently place adolescents at greater risk for the development of psychopathology.     

Methodological artifacts in tests of rational choice theory

Criminal decision making is an inherently natural and highly individualized process; however, rather than allowing participants to self-identify the costs and benefits that impact their own decisions to offend, rational choice researchers have typically provided participants with a uniform list of consequences to consider. Indirect evidence suggests this technique may alter the participants’ perceptions of consequences, yet no study to date has examined this supposition directly. In the current study, participants were randomly assigned to experimental conditions in which they either received a list of traditional costs and benefits to assess or were asked to self-generate their own list to assess. As in past research, when participants were allowed to self-generated consequences they identified several “novel” costs/benefits that have certainty/severity rating comparable to many of the traditionally examined consequences. Results also showed that consequences are more likely to be perceived as possible outcomes (i.e., receive a non-zero probability) when they are presented by researchers than when they are self-generated. Finally, the average certainty and severity of negative consequences do not differ across condition, while ratings of the certainty and value of benefits from crime are relatively lower when they are presented by researchers. Implications for rational choice theory and survey research in criminology more broadly are discussed.     

Rwanda and the question of Commonwealth relevance

Rwanda’s accession to the Commonwealth is often cited as a reason for the organisation’s continued relevance. And yet, in spite of this positioning as poster child for a more cosmopolitan Commonwealth, there is very little evidence, in the corpus of Commonwealth literature, to show how accession of states such as Rwanda boost the argument for relevance. In 2015, I travelled to Rwanda to gain an understanding of the effect that Commonwealth membership has had on the country and vice versa. Using this evidence, I draw conclusions about the effect that Rwanda and the Commonwealth have had on each other.     

Improving data utilization: the case-wise alternative

Both research and practical experience suggest that alternative forms of data analysis and presentation may affect their use in the policy arena. The variable-wise alternative produces estimates of population parameters through conventional statistical techniques. The case-wise alternative defines and identifies qualitatively distinct types of cases through techniques of numerical taxonomy. In the experiment reported here, variable-wise and case-wise presentations of Census data on poverty were used to compare the effects of the alternatives on policy makers in a priority-setting task. The results show that the case-wise alternative can improve utilization, assimilation, recall, and recognition of the data. Under the circumstances examined here, the case-wise alternative is a practical means of increasing the return on the public's investment in data resources to improve policy decisions.
