Chicago Youths’ Exposure to Community Violence: Contextualizing Spatial Dynamics of Violence and the Relationship With Psychological Functioning

This study explores where and when community violence exposure (CVE) matters for psychological functioning in a sample of low-income, racial/ethnic minority youth (M) age = 16.17, 55% female, 69% Black, and 31% Non-Black/Latinx) living in Chicago. CVE was measured with violent crime data that were geocoded in terms of distance from youths’ home and school addresses, and then calculated in terms of three distinct spatial dynamics: chronicity, pervasiveness, and spatial proximity. These measures reflect indirect/objective CVE across different conceptualizations of time, space, and neighborhood context. We tested the relationship between each CVE measure and trait anxiety and behavioral and cognitive dysregulation while controlling for youth-reported, direct violent victimization (e.g., being attacked) to examine how indirect/objective CVE occurring within youths’ neighborhood contexts matters beyond direct/subjective violence exposure. Results revealed that long-term chronic, pervasive, and spatially proximal CVE was related to higher levels of behavioral dysfunction. In contrast, CVE within home- and school-based neighborhoods interacted to predict trait anxiety; youth living in low-crime neighborhoods and attending schools in high-crime neighborhoods had the highest rates of trait anxiety. Measuring CVE within both home and school neighborhoods at specific spatial measurements and time frames is critical to understand and prevent the consequences of CVE.     

Use of a paired-stimulus demand analysis to evaluate demands for inclusion in functional analyses

Clinicians regularly use both indirect and direct assessments to identify preferred stimuli to include in control conditions and positive reinforcement test conditions in a functional analysis (FA). However, clinicians often rely on indirect assessment alone (e.g., caregiver report) to identify aversive stimuli to include in negative reinforcement test conditions. In this study, we evaluate a paired-stimulus demand analysis and validate assessment results via FA. Results indicate that, for all 4 participants, the demands selected least often evoked higher rates of destructive behavior than more frequently selected demands. We identified an escape function for all 4 participants in the escape–least selected (LS) condition (true positive finding) and for only 1 participant in the escape–most selected (MS) condition (false negative finding for 3 of 4 participants). These results support the utility of empirically deriving stimuli for inclusion in the negative reinforcement test condition of an FA to decrease the likelihood of false negative findings.     

Societal rule evaluations: Adolescent offenders' reasoning about moral,conventional, and personal rules

This study investigated adolescent offenders' (81 felons and 83 misdemeanants) evaluations of three types of societal rules (moral, conventional, and personal) on dimensions pertaining to importance, sanctions, authority, and individual choice. In addition, participants selected the acts which should be under personal jurisdiction. Participants provided reasons (i.e., justifications) to support their evaluations. The judgment evidence suggests that the moral rules were considered the most important, the transgressions the most wrong, the violators the most deserving of punishment, and the acts the least acceptable when permitted by an authority. With regard to these same dimensions, conventional rules and violations were ranked second; whereas, the personal rules were ranked third. Offender status differences were obtained for importance ratings and for deservedness of punishment. Justifications for moral events reflected reasoning from both the moral (e.g., other's welfare) and conventional (e.g., social order) domains. Reasoning about conventions involved both conventional and personal concerns; whereas, justifications about personal issues focused on individual prerogatives. The implications of these data are discussed. © 1996 Wiley-Liss, Inc.     

The effect of attitudes on inferences of homosexuality and perceived physical attractiveness in women

A study was conducted to test the hypothesis that inferences of homosexuality will be made more frequently about women who are perceived to be less physically attractive. This hypothesis was supported. More importantly, the investigation was designed to determine whether the perception of a relationship between female homosexuality and level of physical attractiveness would be affected by raters' attitudes about homosexuality and traditional sex-role behavior. Results indicated that female raters with conservative attitudes were likely to associate homosexuality with those women to whom they had given the worst evaluations concerning physical appearance, while more liberal females were less likely to do so. Male raters' attitudes bore little relationship to their evaluations of homosexuality and physical attractiveness. Several interpretations of these results are discussed.     

Speech rate and the development of short-term memory span

Two experiments are reported which examine the effects of word duration on memory span in subjects of different ages. The same linear function relating recall to speech rate (assessed by the speed of repeating words) fits the results of subjects ranging in age from 4 years old to adulthood. It is concluded that developmental increases in short-term memory span can be explained in terms of increases in speech rate and that there is no evidence for an increase in short-term memory capacity. Analyses of the children's speech suggests that increases in speech rate with age reflect increases in the speed of articulation of individual words, rather than any change in the duration of pauses between successive words or changes in coarticulation between words.     

The relationship of early adolescent functioning to parent-reported and adolescent-perceived interparental conflict

Is an adolescent's perception of interparental conflict important or is the parents' report of such conflict sufficient to predict adolescent functioning? To examine this question, a study was undertaken with 178 young adolescents and their mothers, fathers, and social studies teachers. Adolescents completed a measure of their perceptions of interparental conflict while mothers and fathers completed a self-report measure of their conflict. Teachers provided an assessment of each adolescent's cognitive and social functioning at two separate times, 1 year apart. Results indicated that both parental report, particularly maternal, and adolescent perception of interparental conflict were significantly related to adolescent cognitive and social functioning, and the magnitude of the correlations did not differ significantly. Hierarchical regression analyses were performed in which mother and father report of conflict was forced into the equation initially and adolescent perception of such conflict was allowed to enter freely. These analyses indicated that adolescents' perceptions accounted for unique variance in their functioning, beyond that accounted for by parental report. The results are discussed in terms of the specific roles that parental conflict and adolescent perceptions of such conflict play and the possible mechanisms by which each operates.     

Parent-completed and adolescent-completed CDIs: Relationship to adolescent social and cognitive functioning

The purpose of this study was to examine the relationship of both young adolescents' scores on the Children's Depression Inventory (CDI) and their mothers' ratings of the adolescents' depression (parent-completed CDI) to indices of their social and cognitive functioning obtained from a source outside the home. Subjects consisted of a nonclinic sample of 85 young adolescents (11–15 years of age), their mothers, and their social studies teachers. Recent school grades and teacher-completed measures served as the indices of adolescent social and cognitive competence. The results indicated that both adolescents' and mothers' CDI scores were significantly and negatively correlated with measures of adolescent cognitive and social functioning. Multiple regression analyses, utilizing adolescent- and parent-completed CDI scores as predictors, indicated that both predictor variables entered into the equations for cognitive functioning while only the mother-completed CDI entered into those for social functioning. When maternal depression was also entered into the multiple regressions, the findings regarding mother- and adolescent-completed CDI scores were not altered. The relationship of these findings to other somewhat disparate findings concerning the utility of mother and child reports of child depression is discussed.This research was supported, in part, by the William T.
