The effect of a red background on location backward masking by structure

It has been established that diffuse red light partially suppresses the magnocellular (M) visual pathway. Previous research reported that metacontrast masking is reduced (improved accuracy) with a red background, consistent with a reduction in M pathway response from the mask. In contrast, a recent study used location backward masking by noise and found that accuracy decreased with a red background--theoretically due to suppression of the M pathway's initial localization of the target. The present study provides the first report examining the effect of red light on performance in a location backward masking by structure task. Results revealed a main effect of a red (as opposed to a green) background on reducing masking (improved accuracy) with a medium effect size (eta2 = .23). This effect was strongest at the 47- and 60-msec stimulus onset asynchronies. Results suggest that red light primarily decreases interference from the mask in location backward masking by structure.     

A Comparison of Assessment Center Practices in Organizations in German‐speaking Regions and the United States

The development, execution, and evaluation of ACs in 281 German, Swiss, and Austrian organizations are examined for compliance with professional guidelines and consideration of moderator variables of validity, and the results are compared with those reported for U.S. companies ( Spychalski et al., 1997 ). The authors show that some recommendations (e.g., systematic testing of reliability and validity) have not received sufficient attention in either the German‐speaking or U.S. sample and that compliance with guidelines (e.g., the application of information policy to assessees) varies across the countries studied. The most important cross‐national differences in the development, execution, and evaluation of ACs are explained as results of ideologically rooted reservations, insufficient professionalization in some aspects of intraorganizational AC use, as well as specific aspects of the Labor‐Management Act and similar legislation in German‐speaking regions. These factors are linked with a cultural difference—institutionalized collectivism, which is greater in German‐speaking regions than in the United Sates.     

The effects of a target–stimulus reminder on performance in a novel object recognition task

The effects of original training-stimulus pre-test reminders were examined in a novel object recognition (NOR) task. NOR is a task that examines memory for complex stimuli, and is driven by the rats’ tendency to spend significantly more time exploring novel objects over those previously experienced. In this task, a delay is imposed between a training experience during which the animal is allowed to investigate a set of identical objects, and a later test exposure where the animal encounters one of the original objects and a novel object with which it has had no previous experience. Experiment 1 demonstrated that performance at 24 h is significantly worse than at an immediate delay (1 min). In the second experiment, it was demonstrated that neither a 10-s nor a 30-s reminder treatment, in the absence of training, resulted in a level of preference for novelty, a measure of memory for the original object, that was significantly greater than chance. Experiment 3 illustrated significant performance effects of a 30-s training stimulus reminder administered 15 min prior to test with a 24-h retention interval. The final experiment illustrated that the additional 30-s of object exposure is effective in enhancing performance only if it occurs shortly prior to test. Animals receiving the additional 30-s immediately following training did not experience such beneficial effects. It was concluded, based upon these results, that pre-test training-stimulus reminders in this task produce effects similar to those seen in more traditional tasks of learning and memory.     

Work and Family Balance Among Dual-Earner Working-Class Mexican-Americans: Implications for Therapists

The ability to balance work and family demands can affect marital satisfaction, family cohesion, and job satisfaction. While most research in this area has utilized middle-class Anglo-American samples, the present investigation examined dual-earner, working-class Mexican- Americans. Positive relationships were found between work-family balance and satisfaction with marriage, family life and jobs with gender and acculturation showing moderating effects on some variables. Family therapists should be cognizant of the impact of work- family demands on marriage and family functioning even when working class minority families do not offer these issues as presenting problems.     

Learning Through Shared Christian Praxis: Reflective Practice in the Classroom

The cultivation of reflective practice has become a commonly accepted goal of theological education. However, theological educators must face the challenge of teaching and assessing reflective practice. Hypothesizing that this concern is best addressed in community, the authors of this article devised a collaborative action‐research project using Thomas Groome's “shared Christian praxis” model. They describe the ways in which they have, over the course of the project, modified their pedagogy to improve their students' reflection on practice.     

Affordances after spinal cord injury

Spinal cord injury can cause cognitive impairments even when no cerebral lesion is appreciable. As patients are forced to explore the environment in a non-canonical position (i.e., seated on a wheelchair), a modified relation with space can explain motor-related cognitive differences compared to non-injured individuals. Peripersonal space is encoded in motor terms, that is, in relation to the representation of action abilities and is strictly related to the affordance of reachability. In turn, affordances, the action possibilities suggested by relevant properties of the environment, are related to the perceiver's peripersonal space and motor abilities. One might suppose that these motor-related cognitive abilities are compromised when an individual loses the ability to move. We shed light on this issue in 10 patients with paraplegia and 20 matched controls. All have been administered an affordances-related reachability judgement task adapted from Costantini, Ambrosini, Tieri, Sinigaglia, and Committeri (2010, Experimental Brain Research, 207, 95) and neuropsychological tests. Our findings demonstrate that patients and controls show the same level of accuracy in estimating the location of their peripersonal space boundaries, but only controls show the typical overestimation of reaching range. Secondly, patients show a higher variability in their judgements than controls. Importantly, this finding is related to the patients’ ability to perform everyday tasks. Finally, patients are not faster in making their judgements on reachability in peripersonal space, while controls are. Our results suggest that not moving freely or as usual in the environment impact decoding of action-related properties even when the upper limbs are not compromised.     

Mental health and well-being of black women: Toward strategies of empowerment

This review of the literature on Black women's mental health has three goals: 1) to describe the mental health issues, needs, and adaptive behaviors of Black women; 2) to discuss the research, intervention, and public policy efforts of mental health professionals and Black women's groups to address the multiple needs of this population; and 3) to identify effective strategies by which community psychologists can improve the mental health status of Black women through efforts to reduce their environmental stressors, to increase their resources and access to services, and to facilitate their empowerment in American society. The authors propose a number of recommendations to improve Black women's mental health, including changes in research paradigms, changes in education and training programs, and the development of culturally competent service delivery systems.
