Alternatives to traditional mentoring in fostering career success

Researchers have called for an examination of the roles that alternatives to traditional mentoring play in individuals’ career success. This study tests how important, but less examined factors, such as employees’ direct leader, personal and work factors such as ability and the formality of the organization, and employees’ engagement in career management strategies relate to career outcomes. Mechanisms intervening in the relationship between mentoring alternatives and career success were examined, including the moderating effect of individual differences (e.g., proactive personality, career motivation, and career stage) and the mediating role of employees’ career self-efficacy. We discuss how our results continue the examination of alternative sources of mentoring and contribute to existing theory. Finally, we elaborate on the practical importance of our results for situations where alternatives to traditional mentoring are needed.     

Errors are aversive: defensive motivation and the error-related negativity

The error-related negativity (ERN) is a negative deflection in the event-related potential that is maximal approximately 50 ms after the commission of an error. The ERN is generated in the anterior cingulate cortex, a region of the medial prefrontal cortex implicated in both cognitive and emotional processing. Affective and motivational variables influence the magnitude of the ERN, which suggests that the ERN may relate to emotional or motivational aspects of error detection. In the present study, we evaluated the possibility that errors prime defensive motivational responses, and that the ERN may predict the magnitude of defensive reactivity after errors. We found that (a) the defensive startle response was larger following errors than following correct responses, and (b) the magnitude of the ERN predicted the degree of startle potentiation following errors. Thus, response errors prime defensive motivation-and the ERN predicts individual differences in the aversive response to errors.     

网络游戏过度使用者的注意偏向及其ERP特征

网络成瘾与吸烟、饮酒等物质成瘾具有许多相似性,因此也可能存在类似的认知偏向和神经机制。本研究采用事件相关电位技术,通过点探测范式研究网络游戏过度使用者的注意偏向问题。结果显示：（1）与一般使用者相比,网络游戏过度使用者存在明显的注意偏向;（2）游戏图片对网络游戏过度使用者诱发的P2的振幅小于一般使用者;（3）网络游戏过度使用者对游戏图片位置上出现的探测点的加工（P1）较早。结果提示,网络游戏过度使用者的注意偏向存在特定的脑电模式。     

Measurement in Cross-Cultural Neuropsychology

The measurement of cognitive abilities across diverse cultural, racial, and ethnic groups has a contentious history, with broad political, legal, economic, and ethical repercussions. Advances in psychometric methods and converging scientific ideas about genetic variation afford new tools and theoretical contexts to move beyond the reflective analysis of between-group test score discrepancies. Neuropsychology is poised to benefit from these advances to cultivate a richer understanding of the factors that underlie cognitive test score disparities. To this end, the present article considers several topics relevant to the measurement of cognitive abilities across groups from diverse ancestral origins, including fairness and bias, equivalence, diagnostic validity, item response theory, and differential item functioning.     

Caregiver Involvement in the Intensive Mental Health Program: Influence on Changes in Child Functioning

We examined behavioral markers of caregiver involvement and the ways in which family participation was related to treatment outcomes in 47 elementary school children with SED enrolled in a school-based intensive mental health program. Measures of caregiver involvement included therapeutic home visits, attendance at therapeutic meetings, completion of ratings on the daily point sheet, and extra communications with the therapeutic team on the point sheet. Greater initial impairment was associated with greater caregiver involvement. Greater caregiver involvement was linked to improvement in child thought processes, increased ability to provide emotional and social supports for the child, and greater overall child functioning at discharge. Our findings also reflected increased therapists’ attempts to provide additional in-home services in cases where caregivers demonstrated a decline in their ability to provide for their children’s physical and material needs, or in which therapists discovered that the family functioning was more impaired than what was initially assessed. We provide a case study that exemplifies many of these findings.     

Panic disorder: the psychobiology of external treat and introceptive distress

Panic disorder seems to be mediated by the neuronal circuitry and neurochemical systems that have evolved to respond to external threatening stimuli. Distant threats activate prefrontal cortex (involved in complex planning of avoidance strategies), while immediate threats activate midbrain structures (involved in fast reflexive behaviors). Panic disorder may, however, also involve more specific interoceptive mechanisms. For example, the association between respiratory dysfunction and panic disorder has bolstered a false suffocation alarm hypothesis. Genetic and environmental contributors to panic disorder are beginning to be delineated. Effective pharmacotherapy and psychotherapy are able to normalize the relevant psychobiology.     

Contagion and Differentiation in Unethical Behavior: The Effect of One Bad Apple on the Barrel

ABSTRACT— In a world where encounters with dishonesty are frequent, it is important to know if exposure to other people's unethical behavior can increase or decrease an individual's dishonesty. In Experiment 1 , our confederate cheated ostentatiously by finishing a task impossibly quickly and leaving the room with the maximum reward. In line with social-norms theory, participants' level of unethical behavior increased when the confederate was an in-group member, but decreased when the confederate was an out-group member. In Experiment 2 , our confederate instead asked a question about cheating, which merely strengthened the saliency of this possibility. This manipulation decreased the level of unethical behavior among the other group members. These results suggest that individuals' unethicality does not depend on the simple calculations of cost-benefit analysis, but rather depends on the social norms implied by the dishonesty of others and also on the saliency of dishonesty.
