An Evaluation of Postvention Following Adolescent Suicide

This study sought to evaluate postvention provided to two schools following student suicides. A risk index for suicidal behavior among exposed adolescents was devised. The index clearly differentiated high (n = 272) and low (n = 534) scorers on a range of outcome variables. While two-thirds of students attending postvention counselling had two or more putative risk factors for suicidal behavior, a further 231 uncounselled students had similar risk scores. Counselled students (n = 63) did not differ from matched controls (n = 63) at 8-month follow-up on a range of outcome variables. Measures to improve future postvention are discussed.     

Synchrony effects in automatic and controlled retrieval

Using a speeded retrieval procedure, we investigated time-of-day effects in automatic and controlled retrieval. Morning-type adults were tested at either peak (early morning) or off-peak (late afternoon) times on a speeded implicit (Experiment 1) or explicit (Experiment 2) stem completion task. In Experiment 1, retrieval strategies were identified by changes in response speed between a practice phase with rapid retrieval and an implicit memory test phase. Performance based on controlled retrieval (shown by slowdown participants) showed more priming at peak than at off-peak times of day, a finding confirmed in Experiment 2, in which the participants were given intentional retrieval instructions when the materials switched. In contrast, performance based on automatic retrieval (shown by nonslowdown participants) did not differ across peak and off-peak times. The finding suggests a robust synchrony effect in controlled retrieval, but not in automatic retrieval, which does not appear to vary across the day.     

Occupational and Industry Sex Segregation and the Work–Family Interface

This study examines how gender interacts with the extent of occupational and industry sex segregation to affect family-to-work conflict, work-to-family conflict, coworker support, and supportive work-family culture. Using a theoretical framework that highlights the negative ramifications of working in a sex-atypical occupation or industry, we hypothesized that men and women would be impacted differently by the percentage of women in an occupation or industry. The data (N?=?2,810) are from the 2002 National Study of the Changing Workforce (a US sample). Findings suggest that gender interacts with the percentage of women in an industry in significantly predicting coworker support and supportive work–family culture. Gender also interacts with the percentage of women in an occupation in significantly predicting family-to-work conflict.     

The Effects of Salesperson Compensation on Perceptions of Salesperson Honesty1

A reputation for honesty and trustworthiness is important to success in sales. In this article, we report 2 experiments examining the effects on perceived salesperson honesty of information about how the salesperson is compensated (commissions vs. straight salary). In both experiments, commissioned salesmen were perceived as less honest than were noncommissioned salesmen, but compensation method had no effect on the perceived honesty of saleswomen. The discussion of these findings focuses on their implications for sales management.     

Attitudes Toward and Beliefs about Transgender Youth: A Cross-Cultural Comparison Between the United States and India

Using an internet-based survey, we examined attitudes toward transgender youth in the United States and India, two cultures with differences in conceptualizations of gender and treatment of transgender individuals in society, law, and religion. We found generally positive attitudes toward transgender youth in our U.S. (n = 218), but moderately negative ones in our Indian (n = 217), sample. Consistent with the literature on prejudice against transgender adults in many Western societies, general social conservatism in the form of religious beliefs and political ideology, gender-specific conservatism in the form of gender binary belief, and endorsement of environmental rather than biological causes of transgender identity were the best predictors of U.S. participants’ attitudes, although personal contact with gender and sexual minorities also played a role at the bivariate level. These findings suggest that the processes underlying prejudice against transgender youth are similar to those that foster adult-directed transphobia in that cultural context. In contrast, religion-based disapproval and environmental causal attributions were the best predictors of Indian respondents’ attitudes, whereas gender binary belief played only a minor role, and political conservatism and personal contact no role at all. Our regression analyses accounted for considerably more of the variability in U.S. than in Indian participants’ attitudes, highlighting the need for additional (qualitative) work to identify the factors that promote transprejudice in India. We discuss these findings in light of cross-cultural differences between the two countries in terms of our predictors and consider implications for efforts to reduce prejudice against transgender youth.     

Brain Development During the Preschool Years

The preschool years represent a time of expansive mental growth, with the initial expression of many psychological abilities that will continue to be refined into young adulthood. Likewise, brain development during this age is characterized by its ??blossoming?? nature, showing some of its most dynamic and elaborative anatomical and physiological changes. In this article, we review human brain development during the preschool years, sampling scientific evidence from a variety of sources. First, we cover neurobiological foundations of early postnatal development, explaining some of the primary mechanisms seen at a larger scale within neuroimaging studies. Next, we review evidence from both structural and functional imaging studies, which now accounts for a large portion of our current understanding of typical brain development. Within anatomical imaging, we focus on studies of developing brain morphology and tissue properties, including diffusivity of white matter fiber tracts. We also present new data on changes during the preschool years in cortical area, thickness, and volume. Physiological brain development is then reviewed, touching on influential results from several different functional imaging and recording modalities in the preschool and early school-age years, including positron emission tomography (PET), electroencephalography (EEG) and event-related potentials (ERP), functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), and near-infrared spectroscopy (NIRS). Here, more space is devoted to explaining some of the key methodological factors that are required for interpretation. We end with a section on multimodal and multidimensional imaging approaches, which we believe will be critical for increasing our understanding of brain development and its relationship to cognitive and behavioral growth in the preschool years and beyond.     

Time Course of Treatment Effect of OROS(R) Methylphenidate in Children With ADHD

Objective: The authors evaluated the time course of the treatment effect of Osmotic-Release Oral System methylphenidate (OROS(?) MPH) HCl (Concerta(?), Raritan, NJ) CII in children with ADHD. Method: Data were combined from two double-blind, randomized, placebo-controlled, cross-over, analog classroom studies in children (9-12 years) with ADHD. Participants received an individualized dose of placebo or OROS(?) MPH on two laboratory school days. Permanent Product Math Test and Swanson, Kotkin, Agler, M-Flynn, and Pelham scores were evaluated 0.5 hr before dosing and 1, 2, 4, 10, 11, and 12.5 hr post dose. Analysis used a repeated-measures mixed model. Results: Treatment effects were present at all postdose assessment points (p < .0001 for all comparisons, n = 139). Adverse events were similar to previous reports for OROS(?) MPH. Conclusion: A robust treatment effect occurred with OROS(?) MPH; onset was at 1 hr and persisted for at least 12.5 hr after dosing.     

A comparative study of general intelligence in Spanish and Moroccan samples

The aim of this study is to fill a gap in intelligence research by presenting data for the average IQ in Morocco and for a comparable sample in Spain. Adult samples were administered the Raven Standard Progressive Matrices (SPM) (Raven, Court, & Raven, 2001) and scored for the total test and for the three sub-factors of gestalt continuation, verbal-analytical reasoning and visuospatial ability identified by Lynn, Allik, and Irwing (2004). The total test and the three factors have shown satisfactory reliability. Our results for the Moroccan sample show significant relationship between general intelligence factor, gestalt continuation and visuospatial ability with education level and income. Conversely, these variables have been shown to be independent for the Spanish sample. This sample obtained significantly higher scores for the four factors assessed than the Moroccan one. These differences have been found also comparing samples with the same education levels. Finally, the errors percentage for Moroccans has been higher than for Spaniards in all the items, suggesting that the level of difficulty was higher for the Moroccan sample.     

Driver performance, rewards and motivation: A simulator study

It has been suggested that effort invested in a task may be moderated by the perception of the nature of reward offered, e.g., whether social or financial in nature. If levels of payment for empirical work meaningfully influence the effort invested in tasks by participants, the implications may be serious and wide-ranging for the reliability and validity of published data. The study reported in this paper, examines this thesis in a driving context. Thirty-six participants were allocated to either a No payment, Low payment or Medium payment condition in a driving simulator. They undertook both easy and difficult driving scenarios in which performance was measured. Subjective workload and performance results indicated that task difficulty was successfully manipulated with the study. However, in contrast to the previous research in non-driving contexts, participants not receiving rewards were found to perform more poorly and experience increased time pressure.     

Individual differences and propensity to engage with in-vehicle distractions - A self-report survey

Ratings of severity and frequency of engagement with distracting driver behaviours are reported in this paper. Survey data were collected using an anonymous online questionnaire. Four hundred eighty-two respondents contributed to the survey during a 2 month data collection period. Results indicate that the three behaviours rated as most distracting when driving were (i) writing text messages (41%), (ii) reading text messages (62%), and (iii) using a cellular telephone hand-held (52%). The three most frequently reported distracting behaviours that resulted in accidents were (i) ‘interaction with child passengers’ 2.1% (near misses = 7.5%), (ii) both, route guidance destination entry with 2% (near misses = 2.8%) and use of an ‘… add-on media device, e.g., an iPod’ with 2% (near misses = 3.9%), and (iii) the three items ‘reading a text message’, ‘following advice from a route guidance system’, and ‘interaction with pets’, all with 1.7% of respondents reporting an accident when undertaking the activity (with 6.5%, 3%, and 2.2% respectively for near misses). Two hierarchical regression models were explored. The first introducing personal factors, i.e., age, extraversion, agreeableness, conscientiousness, emotional stability and intellect (R² = 0.131, p < 0.001). The second controlled for variables in the first model and introduced driver-related variables, mileage, penalty points, and frequency of accidents with assumed responsibility (R² = 0.253, p < 0.001). This model identified age, extraversion, mileage, penalty points and accidents all to be significant predictors of engagement with unnecessary distractions. The data presents a picture of widespread awareness of, and engagement with, distracting behaviours by drivers in the United Kingdom. Findings from the hierarchical regressions suggest scope may exist to mediate the levels of distracting behaviours by exploring individual differences and driving styles.
