Manipulation of voice onset time during dichotic listening

The manipulation of voice onset time (VOT) during dichotic listening has provided novel insights regarding brain function. To date, the most common design is the utilisation of four VOT conditions: short-long pairs (SL), where a CV syllable with a short VOT is presented to the left ear and a CV syllable with a long VOT is presented to the right ear as well as long-short (LS), short-short (SS) and long-long (LL) pairs. Rimol, Eichele, and Hugdahl (2006) first reported that in healthy adults SL pairs elicit the largest REA while, in fact, LS pairs elicit a significant left ear advantage (LEA). This VOT effect was replicated by Sandmann et al. (2007). A study of children aged 5-8years of age has shown a developmental trajectory whereby long VOTs gradually start to dominate over short VOTs when LS pairs are being presented under dichotic conditions (Westerhausen, Helland, Ofte, & Hugdahl, 2010). Two studies have investigated attentional modulation of the VOT effect in children and adults. The converging evidence from these studies shows that at around 9years of age children lack the adult-like cognitive flexibility required to exert top-down control over stimulus-driven bottom-up processes (Andersson, Llera, Rimol, & Hugdahl, 2008; Arciuli, Rankine, & Monaghan, 2010). Arciuli et al. further demonstrated that this kind of cognitive flexibility is a predictor of proficiency with complex tasks such as reading. A review of each of these studies, the possible mechanisms underlying the VOT effect and directions for future research are discussed.     

Opening up in the classroom: effects of expressive writing on graduate school entrance exam performance

Our study sought to determine whether experimental disclosure could improve exam performance and psychological health in students taking a graduate school entrance exam. Students preparing for the GRE, MCAT, LSAT, or PCAT were randomly assigned to write expressively about their upcoming exam or to a neutral writing condition. Participants completed measures of depressive symptoms and test anxiety before and after writing, and exam scores were collected. The experimental disclosure group had significantly higher test scores and significantly lower pre-exam depressive symptoms than the neutral writing group. Although benefits for depressive symptoms were found in expressive writers regardless of exam type, the advantage of expressive writing for test performance was only observed in students taking the MCAT or LSAT.     

Career decision status as a predictor of resignation behavior five years later

This paper extends earlier research exploring the relationship between career decision status and work outcomes by examining resignation behavior in a group of new graduates five years after initial appointment. On appointment various measures were collected including career decision status variables. Earlier research identified a significant relationship between a number of important work outcomes and career decision status. In the current study two variables–career decidedness and career choice importance–predicted resignation behavior. Those people who on appointment scored higher on career decidedness or lower on career choice importance were significantly more likely to stay in the organization than others. The implications of this finding for individuals and organizations are discussed.     

Depressed people are not less motivated by personal goals but are more pessimistic about attaining them

Despite its theoretical importance, personal goal motivation has rarely been examined in clinical depression. Here we investigate whether clinically depressed persons (n = 23) differ from never-depressed persons (n = 26) on number of freely generated approach and avoidance goals, appraisals of these goals, and reasons why these goals would and would not be achieved. Participants listed approach and avoidance goals separately and generated explanations for why they would (pro) and would not (con) achieve their most important approach and avoidance goals, before rating the importance, likelihood, and perceived control of goal outcomes. Counter to hypothesis, depressed persons did not differ from never-depressed controls on number of approach or avoidance goals, or on the perceived importance of these goals. However, compared to never-depressed controls, depressed individuals gave lower likelihood judgments for desirable approach goal outcomes, tended to give higher likelihood judgments for undesirable to-be-avoided goal outcomes, and gave lower ratings of their control over goal outcomes. Furthermore, although controls generated significantly more pro than con reasons for goal achievement, depressed participants did not. These results suggest that depressed persons do not lack valued goals but are more pessimistic about their likelihood, controllability, and reasons for successful goal attainment.

Factors affecting the involvement of teachers in guidance and counselling as a whole-school approach

This study explores factors affecting the involvement of regular secondary school teachers in the whole-school approach to guidance and counselling by interviewing 12 secondary school teachers in Hong Kong. Emerging themes include teachers' ownership of their role in student guidance and counselling, the alignment of their disposition with education policies, school missions and culture, and their philosophy in education. Findings of what these teachers are actually doing in guidance and counselling are presented. Implications for policy-makers, administrators and leaders for comprehensive guidance and counselling programmes are drawn from constraints that limit interviewees' full potential in assisting students.     

Multiple channel exposure therapy for women with PTSD and comorbid panic attacks

Multiple channel exposure therapy (M-CET; Falsetti & Resnick, 2000) was developed to treat posttraumatic stress disorder (PTSD) with comorbid panic attacks and can be administered in a group format. In addition to being a cost-effective way to provide treatment, group treatment for those with PTSD has been proposed as potentially very beneficial for addressing feelings of shame related to the traumatic event as well as social isolation in general (Foy et al., 2000). Previous studies of M-CET indicate that it may be effective for the treatment of PTSD with comorbid panic attacks (Falsetti et al., 2001, 2003, 2005). The authors examine the relationship of PTSD and panic symptoms pre- and posttreatment and present 6-month follow-up data on the long-term effectiveness of M-CET.     

The relationship between stress and depression in first onsets versus recurrences: a meta-analytic review

S. M. Monroe and K. L. Harkness reviewed the empirical evidence supporting R. M. Post's kindling model, which suggests the 1st episode of depression is more likely to be preceded by major stressors than are subsequent episodes. Their review highlighted the diverse interpretations of Post's premise in the current literature and the changes in research methods that have contributed to this interpretive shift. The authors conducted a meta-analysis (N=13 studies) to test Post's premise that integrated early and recent research and examined potential moderators. A proportion difference effect size was used. Results indicated that 1st onsets of depression were more likely than recurrences to be preceded by severe life events, supporting Post's premise. The moderator analyses suggested that support may be most evident in patient samples and may vary according to age and gender, with less support for Post's premise evidenced in younger samples and in women. Although these results are preliminary, as the analysis included a small number of studies, they suggest that future research should further examine factors that influence the stress-depression relationship with successive recurrences.     

What do children learn about biology from factual information? A comparison of interventions to improve understanding of contagious illnesses

Background . Children have been shown to hold misconceptions about illness, and previous work has indicated that their knowledge can be improved through the use of interventions. Aims . This study aims to evaluate interventions based on the provision of factual information for improving understanding of contagious illness. Sample . The participants were 96 children from two age groups: 7 and 11 years. Methods . During the pre‐test, the children were asked about three contagious illnesses and one novel illness. There were three intervention conditions, differing in the level of factual information provided: explanations provided, no explanations provided and scientific factual style. The interventions were focused on contagious illnesses (cold, chickenpox). A post‐test was conducted 6 weeks later. Results . Results from the pre‐test show that the older children have more sophisticated understanding of illness than the younger children. Mean pre‐ to post‐test change was calculated and analyses revealed that there is greater pre‐ to post‐test change in the explanation and scientific fact conditions when compared with that in the no‐explanation condition. The improvements in knowledge generalized to other contagious illnesses, and the older children showed more improvements than the younger children. Conclusions . These findings add to the literature on children's understanding of contagious illnesses and contribute towards discussions on the best approach to health education.     

Theories of job stress and the role of traditional values: a longitudinal study in China

This study examines how traditionality influences the relationships between job stressors and health. A sample of 496 Chinese employees provided longitudinal questionnaire data, and their health was assessed by collecting blood samples and monitoring blood pressure. The results indicated that the positive relationship between job control and health was stronger among the less traditional workers, whereas the positive relationship between distributive justice and health was stronger among the more traditional workers. Furthermore, traditionality moderated the interactive effects of job demands and perceived control/justice on health. Perceiving higher control mitigated the effects of job demands on upper respiratory infections among low traditionalists, but it exacerbated the effects among the high traditionalists. Perceptions of higher justice mitigated the effects of job demands on emotional exhaustion and immunoglobulin A for high traditionalists but not for low traditionalists. These results suggest that, in the relationship between job demands and psychological and physiological health, concern for equity is an important moderator for individuals with more traditional values, whereas perceived personal control is salutary for health primarily among people with less traditional values.
