Negative priming from ignored distractors in visual selection: A review

Ignoring a distractor on a prime trial generally impairs responses to that object on a subsequent probe trial. This negative-priming (NP) effect supports the notion that distracting objects are actively inhibited during target selection (Tipper, 1985). Alternatively, NP may be caused either by amismatch between the features of items across prime and probe trials (Park & Kanwisher, 1994) or by the episodic retrieval of information from the prime trial which conflicts with the current, correct response (Neill & Valdes, 1992). These alternative accounts are called theselective inhibition,feature mismatching, andepisodic retrieval hypotheses, respectively. The present paper reviews the NP literature and considers the evidence for each of the three accounts. Feature mismatching does produce NP in a limited number of cases, but it is not a necessary condition for NP. In other cases, NP must be due to either selective inhibition or episodic retrieval of previously ignored distractors. Though results from critical tests designed to discriminate among these hypotheses have not yet been reported, such results are crucial for both theoretical and practical reasons.     

Staff support strategies to increase the involvement of individuals with disabilities in meal preparation

In recent years, residential services for persons with disabilities have changed radically, reflecting a shift from custodial care to habilitation and community participation. This has resulted in a significant shift in the roles of direct-care staff. Improvement of staff performance is recognized as a major objective of agencies providing residential support to persons with disabilities. This study examined the gap between existing technologies of support and performance of direct-care staff, and focused on participation in an important activity of daily living, meal preparation. This study compared initial, baseline levels of participation to levels of involvement observed during three experimental intervention phases introduced sequentially within a multiple-baseline design: staff prompting by interventionists, staff self-management, and staff training. Increases from baseline levels of participation were observed for all five participating staff-resident dyads. High levels of variability were observed in some dyads and amounts of increase differed across dyads. Findings are explained in terms of dyad-specific information. A model of staff performance is presented along with implications for high-quality residential service.     

Stressful Job Demands and Worker Health: An Investigation of the Effects of Self-Monitoring1

The hypothesis that self-monitoring would moderate the relationship between work stressors and health was tested on a sample of 136 registered nurses. Results showed that subjects who were more other-directed and who were more concerned with situational appropriateness had more mental and physical distress when exposed to higher levels of work stressors.     

Feminist ideology as a predictor of body dissatisfaction in women

A relationship between feminist attitudes and body satisfaction has been suggested in the literature, but has received no empirical support. Multiple regression analyses were performed on a sample of 200 primarily Caucasian women. Results indicated that after controlling for certain known predictors of body dissatisfaction, the Physical Attractiveness(PA) subscale of the CFIS was negatively related to both General and Specific Body Dissatisfaction, but that the total CFIS score was not. These findings suggest that women's feminist attitudes regarding physical attractiveness relate significantly to body satisfaction, but an overall feminist identification does not. Applications of this finding may contribute to the reduction of women's excessive concerns with their bodies. The authors wish to thank Adele LeMaire for her assistance with the data collection.     

Speaker information affects false recognition of unstudied lexical-semantic associates

Recognition of and memory for a spoken word can be facilitated by a prior presentation of that word spoken by the same talker. However, it is less clear whether this speaker congruency advantage generalizes to facilitate recognition of unheard related words. The present investigation employed a false memory paradigm to examine whether information about a speaker’s identity in items heard by listeners could influence the recognition of novel items (critical intruders) phonologically or semantically related to the studied items. In Experiment 1, false recognition of semantically associated critical intruders was sensitive to speaker information, though only when subjects attended to talker identity during encoding. Results from Experiment 2 also provide some evidence that talker information affects the false recognition of critical intruders. Taken together, the present findings indicate that indexical information is able to contact the lexical-semantic network to affect the processing of unheard words.     

The Diffusion of Youth-Led Participatory Research in Urban Schools: The Role of the Prevention Support System in Implementation and Sustainability

This article discusses the dissemination of a process of youth-led participatory research in urban secondary schools within the Interactive Systems Framework for Dissemination and Implementation (ISF) developed in collaboration with the CDC and its university partners (Wandersman et al. American Journal of Community Psychology, 41(3-4) 2008). The focus here is on the development of the Prevention Support System with respect to general and innovation-specific capacity building. The specific process under study involves youth-led needs assessment and research to inform the planning of prevention programs and policies to address students' health and developmental needs. The article first briefly describes the youth-led research process, its potential benefits, and a case example in two urban secondary schools. It then describes challenges and responses in providing support for the diffusion of this model in 6 secondary schools. The settings are urban public schools with a majority of students of color from diverse ethnic groups: Asian-American, Latino, and African-American. This project constitutes a collaborative partnership with a university school of public health and community-based organizations (CBOs) to build capacity for long-term, sustainable implementation of this innovative process within the local school system. The perspectives of the university-based researcher and the CBO partners on the development and effectiveness of the Prevention Support System are presented.     

The development of the Children's Empathic Attitudes Questionnaire using classical and Rasch analyses

Empathic responding is implicated in antisocial behaviors such as bullying, sexual offending, and violent crime. Identifying children and adolescents at risk for antisocial behavior and evaluating interventions designed to address problem behaviors require valid and reliable measures. Definitional controversies and limited measurement models have hindered measurement. This study describes the development and analysis of the Children's Empathic Attitudes Questionnaire (CEAQ) using both classical and modern techniques. Rasch analyses provided probabilistic results over large item and person groups, enabling meaningful inferences from patterns of responses at the construct level. Analyses of fifth through seventh graders' responses to the final version of the CEAQ provide support for its reliability, validity, and functionality. Four meaningful item clusters were identified, each reflecting more cognitively advanced empathic attitudes. These analyses suggest that the CEAQ provides a theoretically sound, hierarchically meaningful measure of empathic attitudes that will be useful in identification and intervention with children and adolescents at risk for antisocial behavior.     

Does the use of mobile phones affect human short‐term memory or attention?

The effect of acute exposure to low‐level radio frequency electromagnetic fields (REF) generated by mobile phones on short‐term memory and attention was assessed in two experiments. Most of the tests manipulated task difficulty or what might be termed cognitive load. This manipulation is important since previous studies have argued that exposure to mobile phones might affect cognitive functions only under conditions which tax the cognitive system. All participants were exposed to REF (half were exposed to GSM—Global System for Mobile Communication—signals and the other half were exposed to unmodulated signals) in one testing session, while in a separate session participants were exposed to sham signals. To investigate potential lateralised effects, the mobile phone was positioned on the left side of the head for half of the participants and on the right side for the other half. No significant effect of exposure to REF was detected in any of the six tasks used in either the low or high cognitive load conditions. This study used much larger sample sizes than is typical for this type of research and REF exposure was administered under double‐blind conditions. Overall, the results indicate that acute exposure to REFs emitted by mobile phones do not have a strong impact on cognitive functions. Copyright © 2007 John Wiley & Sons, Ltd.
