W&O Psychology in Europe

The role of personality traits in the decision to start a business and to maintain it successfully is discussed controversially in entrepreneurship research. Our meta-analysis builds upon and extends earlier meta-analyses by doing a full analysis of personality traits that includes a comparison of different traits from a theoretical perspective and by analysing a full set of personality predictors for both start-up activities as well as success. Theoretically, our article adds to the literature by matching traits to the tasks of entrepreneurs. The results indicate that traits matched to the task of running a business produced higher effect sizes with business creation than traits that were not matched to the task of running an enterprise, corrected r = .247, K = 47, N = 13,280, and corrected r = .124, K = 20, N = 3975, respectively. Moreover, traits matched to the task produced higher correlations with success, corrected r = .250, K = 42, N = 5607, than traits not matched to the task of running a business, corrected r = .028, K = 13, N = 2777. The traits matched to entrepreneurship significantly correlated with entrepreneurial behaviour (business creation, business success) were need for achievement, generalized self-efficacy, innovativeness, stress tolerance, need for autonomy, and proactive personality. These relationships were of moderate size in general and, moreover, heterogeneity suggested that future research should analyse moderator variables.     

The Quality of the Childrearing Environment of Refugee or Asylum‐Seeking Children and the Best Interests of the Child: Reliability and Validity of the BIC‐Q

The Best Interest of the Child Questionnaire (BIC‐Q) has been designed as an instrument for screening the quality of the rearing situation of asylum‐seeking or refugee children. It is intended to aid legal decisions in asylum procedures. The aim of this study was to determine the reliability and the construct validity of the BIC‐Q. Based on a study sample of refugee or asylum‐seeking children in the Netherlands (N = 74), the psychometric quality of the BIC‐Q was investigated using Cohen's kappa for the inter‐ and intrarater reliability and a nonparametric item response model for the construct validity. The interrater and intrarater reliabilities of the BIC‐Q were good (kappa = .65 and .74 respectively). The results of the item response model revealed that the 14 pedagogical environmental conditions formed a strong and valid measurement scale for the quality of the childrearing environment (H = .55; rho = .94). Preliminary results indicate that the BIC‐Q may be applied to support decisions on where the asylum‐seeking or refugee child has the best opportunities for development.

Academic perceptions of the research evidence base in work and organizational psychology: A European perspective

There has been a growing interest in evidence‐based management. A core component is a body of high‐quality research evidence to inform practice. Initial research with human resource managers in the United States and the Netherlands reveals only modest knowledge about a number of ‘widely documented’ research findings. However, it is unclear whether research experts would display any greater agreement about the research evidence. The present study addresses this issue by exploring levels of agreement about the quality of the research evidence base in work and organizational (W/O) psychology using a pan‐European sample of 75 senior academic W/O psychologists who completed two rounds of a study, first identifying core findings in the field of W/O psychology and then reporting levels of agreement about them. The results show that there were only seven of 24 core findings on which over 75% agreed that there was good‐quality evidence. The challenges of developing and utilizing an evidence‐based approach are discussed and it is concluded, in agreement with Briner and Rousseau (2011a), that there is some way to go before W/O psychologists can begin to feel confident about the quality of much of their research evidence.     

Selective recall of surprising visual scenes. An experimental note on Seligman and Yellen's theory of dreams

Seligman and Yellen (Behav. Res. Ther. 25, 1-24, 1987) reported that dream fragments that are unrelated to the preceding fragments of the same dream are recalled as being more vivid and colorful and are remembered in more detail than dream fragments that are plot related and that lack an element of surprise. The authors take this as support for their hypothesis that while one dreams, two distinct types of visualization occur: one consisting of sudden, emotional bursts and the other occurring as a product of cognitive integration. An alternative explanation of Seligman and Yellen's data is that surprisingness of visual scenes is, in itself, sufficient to produce vivid, detailed, and colorful recall. In order to test this alternative hypothesis, 239 volunteers evaluated target slides that were preceded by either related or unrelated slides. When preceded by unrelated slides, the target slide was experienced as more surprising, was forgotten less often, and was evaluated as more colorful, more detailed, and more vivid. It is concluded that the data given by Seligman and Yellen do not constitute unequivocal support for their hypothesis.     

Neurotoxicity of Kainate to the Hippocampus is not Accrued by Aging, Stress and Exogenous Corticosterone in Wistar Kyoto and Spontaneously Hypertensive Rats

It has been reported that a high corticosterone milieu can exacerbate various experimental insults to the nervous system, in particular to the hippocampus. However, in many of these studies the above milieu was attained by injecting corticosterone in doses (e.g. 10 mg/rat) producing supraphysiological concentrations. In the present study we have investigated whether high plasma corticosterone levels, such as those associated with aging or stress, potentiate a hippocampal excitotoxic insult. Male Wistar Kyoto (WKY) and Spontaneously Hypertensive Rats (SHR) at the age of 6, 12, 18 and 24 months (only WKY for the oldest age) were used. As in other strains, aging in these rats was marked by an increase in basal plasma corticosterone levels. Rats were infused in the dorsal hippocampus with kainic acid (0.035 μg/hippocampus) and the neuronal injury was evaluated within the areas CA3 and CA4. Results indicated that neither aging nor the hypertensive condition affected kainic acid neurotoxicity. In order to study the effect of stress, rats were stressed twice a day, with alternate types of stressors to avoid possible habituation, 3 days prior to and 3 days following the kainic acid infusion. Using this experimental paradigm the hippocampal damage in stressed rats was of the same degree as in non-stressed controls. In a complementary set of experiments, 6 month old WKY and SHR rats were injected with corticosterone (10 mg/rat s.c.). Four hours after administration plasma corticosterone levels in the range of 60-70 μg/100 ml were found. Moreover, a time-course study showed a plasma corticosterone peak in the range of 240 μg/100 ml. Daily corticosterone administration for 3 days before and 3 days after kainic acid infusion potentiated the hippocampal damage in 6 months old SHR but not in the WKY. These results demonstrate that elevation of corticosterone levels within physiological range does not exacerbate hippocampal kainate neurotoxicity and that pharmacological doses of glucocorticoid hormone, which produces plasma levels well above those observable in any physiopathological condition, might, with some strain dependency, potentiate a hippocampal neurotoxic insult.     

Impact of a College Student Academic Mentoring Program on Perceived Parental and Teacher Educational Involvement

This article examines the hypothesis that academic mentoring of college students improves perceived parental and teacher educational involvement. College students were randomly assigned to a 1‐year academic mentoring program (protégés, n = 150) or a control group (n = 167) and completed questionnaires before, during, and after the intervention. Protégés perceived greater levels of parent and teacher educational involvement than did participants from the control group. However, the impact of the mentoring program on perceived parental involvement was found only among students who reported a secure relationship with their parents. Additional analyses suggest that some of these improvements were related to quality of the working alliance between mentors and protégés and to supportive behaviors exhibited by mentors during the intervention.
