Separating Implicit from Explicit Retrieval Processes in Perceptual Identification

Light and Kennison (this issue) proposed that bias effects in the forced-choice perceptual identification of words result from a strategy engaged in by subjects to retrieve explicit information about the words. This article enumerates several problems with this proposal and presents new experimental data against it. It is concluded that subjects do not ordinarily employ an explicit retrieval strategy. The data are discussed in the context of the general problem of separating implicit from explicit influences on performance.     

Academic press and sense of community: Conflict,congruence, and implications for student achievement

This paper examines tensions between two visions of schooling. One stresses social cohesion (i.e., common beliefs, shared activities, and caring relations between members). The other emphasizes strong academic mission (i.e., values and practices that reinforce high standards for student performance). Though not incongruous, numerous organizational studies reveal the potential for social cohesion and communality to be achieved at the expense of academic demand or “press.” To examine their separate and joint effects, measures of academic press and communality are developed from NELS:88 First Follow-up data. Results of hierarchical regression analyses indicate (1) significant links between academic press and student achievement; (2) that academic press has its greatest achievement effect among low-SES schools; (3) that strong sense of community may have a negative impact on achievement in low-SES schools with weak academic press; and (4) that for low- and middle-SES schools, the greatest achievement effects follow from strong combinations of communality and academic press. These findings highlight an important additional component of the “school as community” model, indicating that for most schools, academic press serves as a key prerequisite for the positive achievement effects of communality.

Black and white adolescent males' perceptions of ideal body size

A stratified random sample of 496 white (n =337) and black (n =159) adolescent males participated in a survey of ideal body size beliefs. Responses to the questionnaire and a series of nine female and male body size drawings were analyzed using the General Linear Model Analysis of Variance and Categorical Modeling. Using SES and race as independent variables and BMI (kg/m ²)as a covariate, black males were found to prefer a significantly heavier ideal female body size than whites (p <.0001) and also perceived that their parents, female friends, and male friends would select as ideal a significantly heavier female body size than white subjects. Black subjects were 1.9 times (O.R. = 1.88, 95% C.I. = 1.44, 2.47) more likely to select a larger ideal female hip/buttocks size and 1.7 times (O.R. = 1.72, 95% C.I. = 1.25, 2.37) more likely to choose a larger ideal female thigh size than white subjects. Our findings seem to point toward a greater approval and social acceptance of a larger body size for black females by black males. This study was conducted by the University of South Carolina School of Public Health and funded in part by ASPH-CDC Cooperative Agreement, Center for Disease Prevention and Health Promotion, Centers for Disease Control, Atlanta, Georgia.     

Seeking the source of emotional Stroop interference effects in PTSD: A study of P3s to traumatic words

We investigated the source of emotional Stroop interference effects in posttraumatic stress disorder (PTSD) by measuring reaction times and P3 latencies and amplitudes to personal traumatic, personal positive, and neutral words in a modified Stroop paradigm. Individuals with PTSD were slower to indicate word color, especially for traumatic words, thereby replicating emotional Stroop interference in PTSD. Individuals with PTSD also had significantly reduced and delayed P3 components across word types. Across diagnostic groups, frontal P3 amplitudes were larger to personal positive and traumatic words compared to standard neutral words. However, the absence of Diagnosis x Word Type interactions for P3 measures suggests that individuals with PTSD do not differ from individuals without PTSD in the encoding and recognition of the color of traumatic relative to nontraumatic words, and that Stroop interference does not occur during these early stages of processing.     

Empowerment praxis in community coalitions

Community coalitions address a wide variety of community problems, espousing a community development processes that promotes individual and collective self-determination. They offer a promising venue for the study of empowerment of individuals and organizations. This study utilizes data from members of 35 community coalitions organized for the prevention of alcohol and other drug problems to address the following questions: What individual characteristics are related to the psychological empowerment of coalition members? What organizational characteristics are related to the collective empowering of members? What organization characteristics are related to a coalition being organizationally empowered to succeed in achieving its objectives? At the individual level, psychological empowerment was most strongly related to individuals' participation levels, sense of community, and perceptions of a positive organizational climate. At the group level, the strongest predictors of collective empowering (our operationalization of the empowering organization) were net benefits of participation, commitment, and positive organization climate. Psychological empowerment and positive organizational climate were the two predictors of organizational effectiveness (the empowered organization). Implications and limitations of these findings are discussed.     

Developing Biracial Ethnic Identity: A Review of the Increasing Dilemma

This article describes the current status of biracial youth in the United States. A major purpose is to enhance readers' awareness of the existence of this population and its increasing numerical significance. Models of identity development are presented and relevant sociocultural issues are discussed. In addition, examples of biracial-specific strategies and interventions are offered for consideration by helping professionals.     

The role of emotion control and emotional rumination in stress management training

The present paper reports on three outcome studies evaluating the effectiveness of a new stress management training program. In contrast to conventional stress management, which tends to emphasize life-events, the symptoms of stress and relaxation, the new program is based on emotional rumination, emotion control, and attention control. The training developed from a series of experimental studies on the role of emotional inhibition and rumination in prolonging physiological recovery from stress, and the findings reported here were obtained from a series of applied studies involving police officers from a police force in the North of England. The first two studies employed both self-reported and objective measures of change to demonstrate that the training produced significant increases in job satisfaction and reduced absenteeism, while the results of the final study showed that the benefits of the program were enhanced by follow-up training.     

Ecological influences in youth crisis shelters: Effects of social density and length of stay on youth problem behaviors

For 472 consecutive days we monitored the number of youths residing in a crisis shelter for adolescents, the average length of stay for the youths residing in the shelter on each day, and the number of problem behaviors occurring within the shelter on a daily basis. We analyzed these data using a combination of time series and logistic regression techniques to fit a model that would predict the occurrence of a problem behavior on any given day. After controlling for significant time trends in the data, our results indicate that both the number of youths in the shelter and the proportion of youths who have resided in the shelter longer than 14 days are significantly associated with a problem behavior occurring on any given day. The number of youths in the shelter and the probability of a problem behavior occurring correlated significantly. However, as the proportion of youths who resided in the shelter longer than 14 days increased, the probability of a problem behavior occurring decreased.
