The effects of a mentoring program on at-risk youth

This study examined an intensive mentoring program that focuses on youth deemed at-risk for juvenile delinquency or mental illness. Mothers and teachers completed the Child Behavior Checklist, and youth completed the Hopelessness Scale for Children, the Piers-Harris Self-Concept Scale, and the Self-Report Delinquency Scale. The youth (ages 10 to 17) either participated in the mentoring program (intervention, n = 34) or remained on the waiting list (nonintervention, n = 34) for 6 months. Repeated-measures ANOVAs assessed changes from preintervention to postintervention and indicated significant improvement in problematic behaviors for the intervention group. Mentoring appeared to affect African American youth differently than Caucasian and Latino youth. There were no significant interactions involving gender. The findings of this study supported the positive influence of mentoring on at-risk youth.     

Children's interpretation of generic noun phrases

Generic utterances (e.g., "Cows say 'moo'") have 2 distinctive semantic properties: (a) Generics are generally true, unlike indefinites (e.g., "Bears live in caves" is generic; "I saw some bears in the cave" is indefinite), and (b) generics need not be true of all category members, unlike universal quantifiers (e.g., all, every, each). This article examined whether preschool children and adults appreciate both these features, using a comprehension task (Study 1) and an elicited production task (Study 2). In both tasks, 4-year-old children--like adults--treated generics as distinct from both indefinites ("some") and universal quantifiers ("all"). In contrast, 3-year-olds did not differentiate among generics, "all," and "some." By 4 years of age, generics emerge as a distinct semantic device.     

The importance of irrelevant-dimension variability in the stroop flanker task

Two experiments in which the Stroop flanker task was used were conducted in order to examine the influence of irrelevant dimension invariance on congruency effects. Participants responded manually to a central color patch flanked by a Stroop stimulus. In Experiment 1, invariance in flanker location was found to have no influence on word and color congruency effects. In contrast, invariance of flanker identity led to the disappearance of congruency effects. Experiment 2 indicated that the elimination of a congruency effect was restricted to the dimension that remained constant and did not influence the congruency effect of the other dimension that was presented at the same location. Results suggest that variance is a prerequisite to congruity effects, determining the activation of irrelevant dimensions.     

Vulnerability of facial attractiveness perception to early and multi-year visual deprivation

Judgments of facial attractiveness invariably accompany our perception of faces. Even neonates appear to be capable of making such judgments in a manner consistent with adults. This suggests that the processes supporting facial attractiveness require little, if any, visual experience to manifest. Here we investigate the resilience of these processes to several years of early-onset visual deprivation. Specifically, we study whether congenitally blind children treated several years after birth possess the ability to rate facial attractiveness in a manner congruent to normally sighted individuals. The data reveal significant individual variability in the way each newly sighted child perceives attractiveness. This is in marked contrast to data from normally sighted controls who exhibit strong across-subject agreement in facial attractiveness ratings. This variability may be attributable, in part, to atypical facial encoding strategies used by the newly sighted children. Overall, our results suggest that the development of facial attractiveness perception is likely to be vulnerable to early visual deprivation, pointing to the existence of a possible sensitive period early in the developmental trajectory.     

Well-being during the coronavirus pandemic: The effect of big five personality and COVID-19 beliefs and behaviors

This study examined the relationship between personality traits, COVID-specific beliefs and behaviors, and well-being during the COVID-19 pandemic. In July 2020, at the onset of a second major lockdown, Australian adults (n = 1453) completed measures of Big Five personality, COVID beliefs and behaviors (i.e., belief in a rapid recovery, perceived risk, compliance, change in exercise, and change in interpersonal conflict), subjective well-being and COVID-specific well-being. Personality correlates of COVID-specific well-being differed from those with general life satisfaction. The benefits of conscientiousness were elevated whereas the benefits of extraversion and agreeableness were reduced. Neuroticism was related to greater perceived risk from the pandemic, elevated interpersonal conflict during the pandemic, and more pessimistic views about the rate at which society would recover from the pandemic. In contrast, conscientiousness was notably related to greater compliance with directions from public health authorities. While regression models showed that general well-being was largely explained by personality, COVID factors provided incremental prediction, and this was greatest when predicting COVID-specific well-being and lowest for global evaluations of life satisfaction. The observed prediction by beliefs and behaviors on well-being beyond personality, provides potential opportunities for targeted interventions to support the management of future novel stressors.     

Do the Effects of Adolescent Employment Differ by Employment Intensity and Neighborhood Context?

Research on the effects of adolescent employment on primarily middle‐class youth suggests that intense employment, working more than 15 or 20 hours during the school year, is associated with increased participation in risky behavior. Despite these findings, scholars who focus on the development of youth living in low‐income urban areas often hypothesize that adolescent employment will have beneficial effects on this population. There is some evidence that adolescent employment is associated with increased educational achievement and adult employment for low‐income urban youth. The impact of adolescent employment on future engagement in risky behavior across levels of neighborhood deprivation and employment intensity was investigated on a sample of 1,057 adolescents from the Project on Human Development in Chicago Neighborhoods, a longitudinal study of neighborhood effects on development. After controlling for individual characteristics, intense employment during adolescence did predict increased use of cigarettes and alcohol and having a greater number of sexual partners 2 years after employment was measured. There were no significant interactions between neighborhood SES and adolescent employment status on involvement in risky behavior. These findings suggest that intense adolescent employment is associated with detrimental developmental outcomes for youth regardless neighborhood context.     

THE CHRISTIAN CORE OF INTELLIGENT DESIGN

Intelligent design (ID) theorists assert that ID is a scientific theory that is merely consistent with some religious beliefs. Many critics point to the circumstantial evidence of the apparent development of ID from creation science and the affiliation of ID with mainstream evangelical organizations to assert its religious orientation. This article suggests that the position of ID proponents is a substantial understatement, and that beyond the circumstantial evidence of critics, fundamental Christian doctrine constitutes the essence of ID theory. The bulk of scholarship on ID is polarized into those for and against, as most focus on adjudicating ID truth claims, but this adversarial structure elides some important complexities. This article sets aside the truth claims of ID and focuses more broadly on the discourse in which it is situated to show the Christian core of ID and to examine several hallmarks of religion apparent from this perspective.     

Examining Cognitive Functioning Following TASER Exposure: A Randomized Controlled Trial

Individuals who experience electrical injury suffer significant, sometimes long‐term deficits in neuropsychological functioning. The TASER, an electrical device used by thousands of police departments, generates a high‐voltage (up to 50 000 V), low‐amperage (2.1 mA) current of electricity that is designed to disable a resistive criminal suspect. Questions have emerged regarding the potential for TASER exposure to cause impairment in cognitive functioning. In the current study, healthy human volunteers were randomly assigned to four groups, two of which received a TASER exposure. Participants completed a battery of cognitive tests before and after receiving their assigned treatment. Participants who received a TASER exposure experienced statistically meaningful declines in measures of verbal learning and memory, although deficits lasted less than 1 hour. After TASER exposure, participants also self‐reported significant difficulties with concentration, anxiety, and feeling overwhelmed. Other dimensions of cognitive functioning were not affected. Our findings show that the effects of TASER exposure on brain functioning are not well understood. Copyright © 2015 John Wiley & Sons, Ltd.
