Understanding attraction in formal mentoring relationships from an affective perspective

Despite the critical role affect can play in mentoring, a type of close relationships in the workplace, affect has not received much attention in existing mentoring research. Drawing upon Byrne's affect-centered model of attraction, we examined the relationships among mentors' moods during their interaction with protégés, mentors' liking of protégés, and mentoring support received by protégés. Moreover, we also examined the moderating effect of protégés' emotional intelligence (EI) on the relationship between mentors' moods and liking. Based on data collected from 237 ongoing formal mentoring dyads, we found that mentors' positive moods were positively related, and negative moods were negatively related, to mentoring support received through mentors' liking. Furthermore, protégés' EI only moderated the positive relationship between mentors' positive moods and liking such that the positive relationship was stronger for protégés low on EI. Theoretical and practical implications of the findings are discussed.     

Are “We” Good? A Longitudinal Study of <Emphasis Type="Italic">We</Emphasis>-Talk and Stress Coping in Dual-Earner Couples

We applied the linguistic approach and a longitudinal design to investigate how dual-earner couples address work–family stress and how they reasoned with communal coping to reduce work–family stress. Although previous research indicated that we-talk may be a marker for communal coping, we argued that gender may differ in the psychological meanings of we-talk. We hypothesized that gender moderated the relationships between we-talk and satisfaction in both work and marriage. Thirty-one dual-earner couples were interviewed about how they coped with work–family stress. The data concerning work and marital satisfaction were collected twice, once during the interview and once 2 years later. The results indicated significant interactions between gender and we-talk in regard to both marital and work satisfaction. Specifically, we-talk that was used by wives increased their husbands’ work and marital satisfaction. In contrast, we-talk that was used by husbands decreased their wives’ work satisfaction. Our findings highlighted that the psychological meanings of we-talk were dependent on the talking context. The applications for reducing work–family stress were discussed.     

Relationship between students' self-assessment of their capabilities and their teachers' judgments of students' capabilities in mathematics problem-solving

The study examined the judgments made by four seventh-grade mathematics teachers of their 107 students' competence in solving mathematics problems. Simultaneously, the 107 students made self-efficacy judgments about their capability in solving mathematics problems. The two sets of judgments were tested for predicting students' mathematics performance. Also, students' prior mathematics achievement was studied for its influence on both teachers' and students' judgments and students' mathematics performance. Teachers were asked to make judgments of each student for every mathematics problem solved. Results were consistent with prior research indicating that students' mathematics self-efficacy beliefs were highly predictive of their performance. Path analysis indicated that the mathematics teachers' judgments were also highly predictive of students' performance and self-efficacy. In turn, these variables predicted students' postperformance judgments. Combining students' self-efficacy judgments and teachers' judgments of students increased predictiveness for students' mathematics performance. Educational implications were also discussed.     

Psychiatric diagnoses of patients visiting a sleep disorder clinic due to dyssomnias

This study analyzed the demographic characteristics and psychiatric diagnoses of 90 consecutive patients who visited a sleep disorder clinic in Taiwan with complaints of insomnia (difficulty initiating or maintaining sleep, or nonrestorative sleep) or hypersomnia (excessive sleepiness as evidenced by either prolonged sleep episodes or daytime sleep episodes that occur almost daily). All subjects were interviewed using a sleep disturbance questionnaire and the structured Mini-International Neuropsychiatric Interview supplemented by the DSM-IV criteria for psychiatric diagnoses. Among 90 patients, 79 were classified as having insomnia and 11 had hypersomnia. 53 patients also had psychiatric diagnoses other than sleep disorders. Patients with insomnia had a significantly higher rate of comorbidities with other psychiatric diagnoses (65.8%) than did subjects with hypersomnia (9.1%). These results emphasize the importance of psychiatric evaluation of patients with complaints of sleep disturbance.     

Do Investment Risk Tolerance Attitudes Predict Portfolio Risk?

We investigated a new instrument designed to assess investment risk tolerance, the Risk Tolerance Questionnaire (RTQ). RTQ scores were positively correlated with scores on two other investment risk measures, but were not correlated with a measure of sensation-seeking (Zuckerman, 1994), suggesting that investment risk tolerance is not explainable by a general cross-domain appetite for risk. Importantly, RTQ scores were positively correlated with the riskiness of respondents’ actual investment portfolios, meaning that investors with high risk-tolerance score tend to have higher-risk portfolios. Finally, respondents with relatively more investment experience had more risk-tolerant responses and higher-risk portfolios than less experienced investors.

Electrophysiological difference between the representations of causal judgment and associative judgment in semantic memory

Causally related concepts like “virus” and “epidemic” and general associatively related concepts like “ring” and “emerald” are represented and accessed separately. The Evoked Response Potential (ERP) procedure was used to examine the representations of causal judgment and associative judgment in semantic memory. Participants were required to remember a task cue (causal or associative) presented at the beginning of each trial, and assess whether the relationship between subsequently presented words matched the initial task cue. The ERP data showed that an N400 effect (250–450 ms) was more negative for unrelated words than for all related words. Furthermore, the N400 effect elicited by causal relations was more positive than for associative relations in causal cue condition, whereas no significant difference was found in the associative cue condition. The centrally distributed late ERP component (650–750 ms) elicited by the causal cue condition was more positive than for the associative cue condition. These results suggested that the processing of causal judgment and associative judgment in semantic memory recruited different degrees of attentional and executive resources.     

Retest stability of DSM-III-R diagnoses among adolescents using the diagnostic interview schedule for children (DISC-2.1C)

Retest stability of DSM-III-R diagnoses was assessed using the DISC-2.1C with a sample of Anglo, African, and Hispanic American adolescent patients 12 to 17 years of age. Based on the kappa statistic, retest stability was fair for any disorder ( =.50), for any anxiety disorder ( =.44), for any affective disorder ( =.53), for any disruptive behavior disorder ( =.58), and for substance use disorders ( =.46). Although there was a trend for reliability to be somewhat higher for African Americans ( =.58) than for Anglos ( =.42) or Hispanics ( =.49), these differences were not statistically significant. In general, 15- to 17-year-olds had somewhat better reliability ( =.58) than did 12- to 14-year-olds ( =.44). Males had somewhat higher reliability ( =.63) than females ( =.43). These findings are congruent with those reported recently using the DISC-R (Schwab-Stone et al., 1993) and suggest that the DISC appears to be at least as reliable as other available child diagnostic instruments. In view of the fair-to-moderate levels of reliability of these instruments in general, future research should focus on the joint effects of instrument, subject, interviewer, and nomenclature on operating characteristics of diagnostic interview schedules, focusing in particular on factors affecting accurate recall and reporting of symptoms and episodes.
