The Mentoring Relationship Challenges Scale: The impact of mentoring stage, type, and gender

The current study investigated the role of relational challenges as reported by 309 protégés in various stages and types of mentoring relationships. The Mentoring Relationship Challenges Scale (MRCS) was newly constructed using the results of an earlier qualitative study (Ensher & Murphy, 2005). The scale measured three factors of relational challenges which were: Demonstrating Commitment and Resilience, Measuring Up to a Mentor's Standards, and Career Goal and Risk Orientation. The results demonstrated that with respect to mentoring stages, those protégés in the beginning stages of their relationships reported experiencing significantly fewer challenges related to Demonstrating Commitment and Resilience than those in the mature or ending stages of the relationship. Also, it was found that the type of mentoring relationship (traditional, step-ahead, or peer) affected the prevalence of the three types of challenges. Protégés in peer relationships reported significantly fewer of all three types of challenges than those in step-ahead or traditional relationships. However, contrary to predictions, there were no significant differences found between those in informal versus those in formal mentoring relationships. As expected, protégé and mentor gender interacted significantly. Female protégés reported experiencing significantly fewer challenges related to the factor of Measuring Up to a Mentor's Standards, than did male protégés. Also, female protégés reported experiencing a significantly higher degree of relational challenges related to Career Goal and Risk Orientation from their male mentors than from their female mentors. Finally, after controlling for perceptions of career and psychosocial support for protégés in traditional mentoring relationships, two of the three relational challenges factors remained significant and explained a significant amount of variance in overall satisfaction with the mentoring relationship. This suggests that relational challenges, at least for traditional mentoring relationships, serve as an important mechanism to impact overall relationship satisfaction.     

Positive illusions about a partner’s personality and relationship quality

Previous studies have shown individuals to hold positive biases about their relationships. The present study examined positive illusions about a partner’s specific personality characteristics in relation to relationship quality and personality. Both partners of 120 heterosexual couples participated in the present study, making it possible to examine both partner and actor effects. Results showed that although, in general, individuals did not hold positive illusions about a partner’s specific personality characteristics, positive illusions were positively related to relationship quality. In addition, interesting relations emerged between positive illusions about a partner’s personality and both individuals’ personality and marital duration.     

Sexual arousal and the pursuit of attractive mating opportunities

From an evolutionary perspective, sexual arousal may function, in part, to motivate the pursuit of attractive mating opportunities. We designed a study to test three aspects of this hypothesis. Several hundred heterosexual men and women completed a short survey about sexual arousal in response to a casual sex mating opportunity. We replicated previous research documenting that men report greater sexual arousal than women in response to a short-term mating opportunity. We argue that it is unlikely that a “downplaying of alternatives” psychology evolved, whereby mated individuals rate opposite-sex targets as less attractive than do unmated individuals, but instead that men and women have a relationship-seeking psychology, motivating them to pursue attractive mating opportunities. The results supported this relationship-seeking psychology rather than a downplaying alternatives psychology. Discussion addresses directions for future research on the motivational properties of sexual arousal.     

Sex drive, attachment style, relationship status and previous infidelity as predictors of sex differences in romantic jealousy

Recent research examining sex differences in jealousy suggests that more men than women tend to be distressed by sexual infidelity, and that more women than men tend to be distressed by emotional infidelity. The primary explanation for these findings is that evolution has shaped men’s and women’s responses to enhance their chances of reproductive success. However, within-sex differences are also found in terms of relative level of distress at sexual or emotional infidelity. This study examined the effect of alternative variables, particularly those associated with attachment and sexual motivations, on both between- and within-sex differences in relative distress at sexual and emotional infidelity. A community sample of 437 adults provided data using a self-report questionnaire. The results showed that sex drive was a significant predictor of distress at jealousy for both men and women, while attachment avoidance and previously being the victim of a sexual infidelity were significant predictors for men only, and relationship status was a significant predictor for women only. Overall, these findings support the evolutionary model of jealousy, and suggest that sex-specific evolved psychological mechanisms underpinning jealousy are influenced by attachment and sexual motivations.     

The role of self-regulation in derogating attractive alternatives

The present research addresses the question of how romantically involved individuals are able to shield their ongoing romantic relationship from the temptation of attractive alternative partners. Specifically, two studies examined, and supported, the prediction that self-regulation promotes romantically involved individuals’ tendency to derogate attractive others as potential partners. Heterosexual participants responded to pictures of attractive and unattractive opposite-sex others by indicating their interest in these others as potential partners. In both studies the possibility for self-regulation exertion was manipulated (by means of self-regulation depletion in Study 1, and time-pressure in Study 2). When self-regulatory resources were relatively high, romantically involved participants exhibited less interest in attractive opposite-sex others than non-involved participants. However, when self-regulatory resources were low, interest in attractive opposite-sex others did not differ between romantically involved and non-involved participants.     

Statistical Significance Levels of Nonparametric Tests Biased by Heterogeneous Variances of Treatment Groups

The statistical significance levels of the Wilcoxon-Mann-Whitney test and the Kruskal-Wallis test are substantially biased by heterogeneous variances of treatment groups—even when sample sizes are equal. Under these conditions, the Type I error probabilities of the nonparametric tests, performed at the .01, .05, and .10 significance levels, increase by as much as 40%-50% in many cases and sometimes as much as 300%. The bias increases systematically as the ratio of standard deviations of treatment groups increases and remains fairly constant for various sample sizes. There is no indication that Type I error probabilities approach the significance level asymptotically as sample size increases.     

联系可觉察度对错误记忆的影响

本研究采用DRM词表学习法和图片刺激对学习法两种研究范式考察了关键诱饵与学习项目间联系可觉察度对错误记忆的影响。结果显示,学习项目与关键诱饵的联系可觉察度对错误记忆起重要作用:在词表学习范式中,随着联系可觉察度的提高,被试觉察到的词表的关联性更高,错误记忆就更容易发生;在刺激对学习范式中,随着联系可觉察度的提高,学习项目和关键诱饵间的差异区分性提高,导致二者间的关联性降低,从而减少错误记忆。本研究为进一步揭示错误记忆的机制、更好地理解记忆及其机制提供了新的证据,并对如何提高记忆效率具有一定的实际应用价值。     

The effect of stereotype threat on student-athlete math performance

ObjectivesTo assess whether a subtle stereotype threat of student-athletes would cause a decrease in both academic effort and performance.DesignA 2 (Male/Female) x 2 (Athlete Prime/No Athlete Prime) design was used to assess effort and performance on a math test.MethodA subtle threat manipulation was used to prime half of 60 NCAA Division III student-athletes with their athletic identity prior to taking a difficult math test.ResultsSupporting the hypotheses, student-athletes who were primed with their athletic identity attempted significantly fewer problems and received lower mean math scores than those who were not primed. Contrary to hypotheses, gender did not impact effort or performance, and there was no evidence of buffering effects of priming non-athlete identities.ConclusionsThe results of this experiment provide evidence for stereotype threat effects across genders and into Division III athletes, which potentially impact student-athlete academic performance.     

A Prevalence Study on Internalizing Problems Among Primary School Children in Hong Kong

Studies in Hong Kong indicated that there is a tendency for young children to use internalizing as a means to cope with their daily difficulties. Mother–child relationship has been seen as a factor affecting a child’s adaptive coping skills. In this study, we explored the prevalence of internalizing problems among primary school children in Hong Kong, as well as the mother–child relationship that contribute to children’s internalizing problems. Data used to assess the internalizing behavior among 1598 primary school children were collected from their mothers. The estimated prevalence of internalizing problem was 11.4%. This prevalence was based on the cutoff point for internalizing disorders according to the Child Behavior Checklist (CBCL). The CBCL internalizing score was significantly correlated with mother–child relationship as measured using the Parent–Child Relationship Questionnaire (PCRQ). Results from the PCRQ indicated that children’s internalizing problems were positively correlated with mother’s use of verbal punishment and rejection as well as their possessiveness and protection on their children. On the other hand, a nurturing and intimate relationship between mother and child was an important factor contributing to the development of mentally healthy children. Implications of this study and suggestions for further research were discussed.
