School readiness in children living in non-parental care: Impacts of Head Start

The current study examines the effects of Head Start on the development of school readiness outcomes for children living in non-parental care. Data were obtained from the Head Start Impact Study, a randomized controlled trial of Head Start conducted with a nationally representative sample of Head Start programs and families. The sample included 253 children living in non-parental care (defined as a primary caregiver who self-identified as someone other than a biological, adoptive, or step-parent), who experienced elevated rates of child and family risk factors. Results revealed modest direct short-term and indirect longer-term impacts of Head Start on school readiness outcomes (increased pre-academic skills, more positive teacher–child relationships, and reductions in behavior problems) for children living in non-parental care. Limitations of this study and directions for future research are discussed.     

Is the world a just place? Countering the negative consequences of pervasive discrimination by affirming the world as just

Two studies (a) explored the role of pervasiveness of discrimination (pervasive vs. rare) in determining targets' responses to discrimination, and (b) examined the extent to which threats to participants' worldview can account, in part, for detrimental effects of pervasive discrimination. As predicted, across both studies, pervasiveness of discrimination moderated the relationship between attributions to prejudice for failure to obtain a job and psychological well-being (depressed affect and state self-esteem). When discrimination was presented as pervasive, attributions to prejudice related to lower state self-esteem and greater depressed affect. When discrimination was portrayed as rare, attributions to prejudice were related to higher state self-esteem and unrelated to depressed affect. Study 2 further showed that being able to affirm the world as just countered the negative consequences of pervasive discrimination, whereas it did not influence responses to discrimination that was perceived as rare.     

Contributions of area Te2 to rat recognition memory

Ablations and local intracerebral infusions were used to determine the role of rat temporal association cortex (area Te2) in object recognition memory, so that this role might be compared with that of the adjacent perirhinal cortex (PRH). Bilateral lesions of Te2 impaired recognition memory measured by preferential exploration of a novel rather than a familiar object at delays ≥20 min but not after a 5-min delay. Local infusion bilaterally into Te2 of (1) CNQX to block AMPA/kainate receptors or (2) lidocaine to block axonal transmission or (3) AP5, an NMDA receptor antagonist, impaired recognition memory after a 24-h but not a 20-min delay. In PRH all these manipulations impair recognition memory after a 20-min as well as a 24-h delay. UBP302, a GluK1 kainate receptor antagonist, impaired recognition memory after a 24-h but not a 20-min delay, contrasting with its action in PRH where it impairs only shorter-term (20 min) recognition memory. Also in contrast to PRH, infusion of the muscarinic receptor antagonist scopolamine was without effect. The Te2 impairments could not readily be ascribed to perceptual deficits. Hence, Te2 is essential for object recognition memory at delays >5 or 20 min. Thus, at long delays both area Te2 and PRH are necessary for object recognition memory.     

When team members’ values differ: The moderating role of team leadership

Integrating theory and research on values, diversity, situational strength, and team leadership, we proposed that team leadership moderates the effects of values diversity on team conflict. In a longitudinal survey study of national service teams, we found significant, but opposite, moderating effects of task-focused and person-focused leadership. As predicted, task-focused leadership attenuated the diversity–conflict relationship, while person-focused leadership exacerbated the diversity–conflict relationship. More specifically, task-focused leadership decreased the relationship between work ethic diversity and team conflict. Person-focused leadership increased the relationship between traditionalism diversity and team conflict. Team conflict mediated the effects of the interactions of leadership and values diversity on team effectiveness.     

Costs and benefits of dropout schedules of test–restudy practice: Implications for student learning

Almost all previous studies examining the benefits of testing for promoting student learning have used fixed schedules of practice. However, students more often report utilizing a dropout schedule of practice, in which items are dropped from practice once they are known. Two experiments investigated the costs and benefits of utilizing a dropout schedule of test–restudy practice. Participants learned Swahili–English paired associates using a dropout schedule or a fixed schedule. In the dropout schedule, items received test–restudy practice until each item was correctly recalled once. In the fixed schedule, all items received three tests–restudy practice trials regardless of whether they were correctly recalled, as in previous research. Experiment 2 also included a second learning session. In both experiments, a final cued recall test was administered several days later. Results indicated that the benefits of the dropout schedule (fewer practice trials used overall and all items correctly recalled once during practice) need to be considered in light of the costs (lower levels of final test performance).

Mating interest improves women's accuracy in judging male sexual orientation

People can accurately infer others' traits and group memberships across several domains. We examined heterosexual women's accuracy in judging male sexual orientation across the fertility cycle (Study 1) and found that women's accuracy was significantly greater the nearer they were to peak ovulation. In contrast, women's accuracy was not related to their fertility when they judged the sexual orientations of other women (Study 2). Increased sexual interest brought about by the increased likelihood of conception near ovulation may therefore influence women's sensitivity to male sexual orientation. To test this hypothesis, we manipulated women's interest in mating using an unobtrusive priming task (Study 3). Women primed with romantic thoughts showed significantly greater accuracy in their categorizations of male sexual orientation (but not female sexual orientation) compared with women who were not primed. The accuracy of judgments of male sexual orientation therefore appears to be influenced by both natural variations in female perceivers' fertility and experimentally manipulated cognitive frames.     

A proximal change experiment testing two communication exercises with intimate partner violent men

This study tests the immediate impact of two interventions for intimate partner violent (IPV) men in affecting behavioral and emotional change during arguments with their partners. Couples with an abusive male partner (N = 100) discussed an area of conflict twice, interrupted by a brief intervention. Men were randomly assigned to receive (a) an editing-out-the-negative skills training, (b) an accepting influence skills training, or (c) a time-out. IPV men in both skills-training conditions showed greater decreases in aggressive feelings than IPV men in the time-out condition based on their self-report and observed affective behavior. Women also reported feeling less aggressive when their husbands were assigned to one of the skills-training conditions as compared to the control (time-out) condition. Results suggest that IPV men can learn to adopt new communication skills and that they do appear to have a positive impact on the emotional tone of their arguments. Clinically, communication skills training may be a useful addition to battering intervention programs, although these skills may need to be taught to both men and women involved in violent relationships.     

Early orthographic influences on phonemic awareness tasks: Evidence from a preschool training study

Experienced readers show influences of orthographic knowledge on tasks ostensibly tapping phonemic awareness. Here we draw on data from an experimental training study to demonstrate that even preschoolers show influences of their emerging orthographic abilities in such tasks. A total of 40 children were taught some letter-sound correspondences but not others. A selective effect of this training was found on their phonemic awareness task performance for the trained items. These findings point to the multidetermined nature of performance on tasks normally considered as measuring phonemic awareness and have implications for theories of the role of phonemic awareness in reading acquisition.     

Integrating complementary and alternative therapies into psychological practice: A qualitative analysis

Although complementary and alternative therapies (CATs) are utilised widely for treating psychological disorders, little research has examined psychologists' beliefs about integrating CAT into psychological practice. Six practicing psychologists and six psychology students were interviewed about their CAT integration beliefs, in particular integrating CAT into clinical practice via recommending CATs, offering referrals to CAT practitioners, or undertaking training to utilise CATs within psychological practice. Guided broadly from a theory of planned behaviour perspective, participants raised a number of costs and benefits, discussed referent groups who would influence their decisions, and suggested motivators and barriers for integration. A number of additional themes were raised, including risks, such as the possibility of litigation and the need for clear Society guidelines, as most participants were unclear about what constitutes appropriate practice. Identifying these themes serves as an important initial step to informing discussion and policy for this emerging practice issue within psychology.     

An Examination of the Psychologists' Attitudes Towards Complementary and Alternative Therapies Scale Within a Practitioner Sample

This study assessed the validity of a scale measuring psychologists' attitudes towards complementary and alternative therapies and compared the attitudes of psychologists with a previous sample of psychology students. The scale, derived from existing measures for medical professionals and previously tested on a sample of psychology students, was completed by practising psychologists (N = 122). The data were factor analysed, and three correlated subscales were identified, assessing the perceived importance of knowledge about available therapies, attitudes towards integration with psychological practice, and concerns about associated risks of use. This structure was similar, but not identical, to that found in a previous sample of psychology students; however, psychologists expressed more concern for risks associated with integration and were less likely to hold a positive attitude towards integration. This scale will be useful in gauging changes in psychologists' attitudes towards integrative practice over time.
