The Interactive Effects of Race,Gender, and Job Type on Job Suitability Ratings and Selection Decisions1

The present study examined the main and interactive effects of race, gender, and job type on job suitability ratings and selection decisions. Consistent with the double‐advantage additive effects model of race and gender, highly educated Black women were rated as more suitable for jobs and more likely to be selected for jobs requiring high levels of cognitive ability than were comparably educated White men, White women, or Black men. These results suggest that selection decisions might be jointly determined by race, gender, and the nature of a job. The implications of these findings for overcoming biases in employment‐related decision making are discussed.     

Effects of positive and negative affect and emotional suppression on short-term life satisfaction

Relationships between emotional experiences and health and adjustment are influenced by many variables, with emotional suppression (ES) being one of the most influential factors. In the current study, we examined the effects of affect and ES on short-term life satisfaction (LS) measured over the previous week. We also considered the dimension of activation status for both positive affect (PA) and negative affect (NA). The final sample included data collected from 398 undergraduates (184 men and 214 women). Participants answered six questionnaires, two of which were used for another study. All of the tests were of Japanese versions and were answered with regard to the previous week's experiences. Results showed that LS was positively associated with PA and negatively with NA, but that the positive association was stronger for activated PA than deactivated PA, while the negative association was stronger for deactivated NA than activated NA. Furthermore, an interactive effect between deactivated NA and ES on LS was significant in men, where post hoc tests demonstrated that deactivated NA was more negatively associated with LS when ES was higher. This study suggests that activated and deactivated affect differ in their effects on LS. In addition, it is likely that the detrimental effect of deactivated NA on LS is larger when NA is more strongly suppressed. The necessity of interventional research along with the limitations of this study is discussed for future research.     

Associative learning acquisition and retention depends on developmental stage in Lymnaea stagnalis

Associative learning dependent on visual and vestibular sensory neurons and the underlying cellular mechanisms have been well characterized in Hermissenda but not yet in Lymnaea. Three days of conditioning with paired presentations of a light flash (conditional stimulus: CS) and orbital rotation (unconditional stimulus: UCS) in intact Lymnaea stagnalis results in a whole-body withdrawal response (WBWR) to the CS. In the current study, we examined the optimal stimulus conditions for associative learning, including developmental stage, number of stimuli, interstimulus interval, and intertrial interval. Animals with a shell length longer than 18 mm (sexually mature) acquired and retained the associative memory, while younger ones having a shell length shorter than 15 mm acquired but did not retain the memory to the following day. For mature animals, 10 paired presentations of the CS and UCS presented every 2 min were sufficient for the induction of a WBWR to the CS. Furthermore, animals conditioned with the UCS presented simultaneously with the last 2 s of the CS also exhibited a significant WBWR in response to the CS. Blind animals did not acquire the associative memory, suggesting that ocular photoreceptors, and not dermal photoreceptors, detected the CS. These results show that maturity was key to retention of associative learning.     

Perceptual narrowing towards adult faces is a cross‐cultural phenomenon in infancy: a behavioral and near‐infrared spectroscopy study with Japanese infants

Recent data showed that, in Caucasian infants, perceptual narrowing occurs for own‐race adult faces between 3 and 9 months of age, possibly as a consequence of the extensive amount of social and perceptual experience accumulated with caregivers and/or other adult individuals of the same race of the caregiver. The neural correlates of this developmental process remain unexplored, and it is currently unknown whether perceptual tuning towards adult faces can be extended to other cultures. To this end, in the current study we tested the ability of 3‐ and 9‐month‐old Japanese infants to discriminate among adult and infant Asian faces in a visual familiarization task (Experiment 1), and compared 9‐month‐olds’ cerebral hemodynamic responses to adult and infant faces as measured by near‐infrared spectroscopy (NIRS) (Experiment 2). Results showed that 3‐month‐olds exhibit above‐chance discrimination of adult and infant faces, whereas 9‐month‐olds discriminate adult faces but not infant faces (Experiment 1). Moreover, adult faces, but not infant faces, induced significant increases in hemodynamic responses in the right temporal areas of 9‐month‐old infants. Overall, our data suggest that perceptual narrowing towards adult faces is a cross‐cultural phenomenon occurring between 3 and 9 months of age, and translates by 9 months of age into a right‐hemispheric specialization in the processing of adult faces.     

Stress coping and the adjustment process among university freshmen

The purpose of the present study was to investigate causal relationships between dispositional and situational coping and health status in university freshmen. Two hundred and twenty-nine university freshmen completed questionnaires at Time 1 (immediately after university matriculation) and at Time 2 (approximately three months later) in a short-term, prospective study. Structural equation modeling was used to analyze causal relationships between four coping strategies (i.e., emotion expression, emotional support seeking, cognitive reinterpretation, and problem solving) and four health status variables (i.e., somatic symptoms, anxiety and insomnia, social dysfunction, and depression). Increases in dispositional coping predicted increases in situational coping at certain time points. In addition, increases in dispositional emotion-focused coping, such as emotion expression and emotional support seeking, predicted poor health status. This relationship was mediated by situational coping variables. Finally, increases in dispositional problem-focused coping, such as cognitive reinterpretation and problem solving, predicted better health status. This relationship was direct or indirectly mediated by situational coping variables. Our data suggest that the use of coping skills such as cognitive reinterpretation and problem solving may promote better health and adaptation in university freshmen.     

Power imbalance,its legitimacy,and aggression

Sixty Japanese female students were asked to exchange shocks in electric roulette games with female opponents. The subjects were assigned to either the 80%, 50%, or 20% win conditions. Half of them were then led to judge that the power unbalance was legitimate by being informed that the assignment was based on a prior performance contest, with the good performer being assigned to the advantageous position. The other subjects were led to perceive the power imbalance as illegitimate by being informed that the assignment was randomly decided. The opponents always severely attacked them. The retaliation by the subjects was analyzed by a two-way ANOVA with Power Imbalance and Legitimacy. It was found that the subjects both in the 20% and 50% win conditions set more intense shocks to their opponents than those in the 80% win condition. This is not consistent with the fear of retaliation hypothesis which had predicted that the subjects would refrain from intensely aggressing against the opponent who had a greater aggressive capacity. It was also found that in the 80% win condition, the subjects set more intense shocks when the unbalance had been determined by their performance than when determined by luck, whereas in the 20% win condition, they set more intense shocks when the imbalance had been determined by luck than when determined by their performance. These suggest that retaliation depended upon perceived justifiability of aggression which was predicated on the legitimacy of the power imbalance. Finding in the 50% win condition that the shock settings were higher when the power imbalance had been determined by their performance than when determined by luck was interpreted in terms of their heightened competitiveness.     

Super-ordinary bias in Japanese self-predictions of future life events

Japanese are said to value being ordinary and emphasize similarity with others. We theorized that Japanese tend to perceive themselves as being ordinary, so much so that their self-predictions about future life events are biased (super-ordinary bias). Specifically, it was expected that Japanese overestimate the likelihood of experiencing common events (such as getting married or catching the flu) and underestimate the likelihood of experiencing rare events (such as winning a lottery or being murdered). We examined the effects of commonness and desirability of future life events on the relative-likelihood estimates. Our expectation was supported by three studies, involving a questionnaire, a laboratory experiment, and a mail survey. Findings are consistent with the assumed tendency to view oneself as being super-ordinary. The super-ordinary bias was also found to be independent of unrealistic optimism or pessimism.     

Barriers to use of mental health services by Japanese university students

The present cross-sectional study assessed the attitude of Japanese undergraduates towards mental health services and investigated whether mental distress is associated with reluctance to use, and a decreased perceived need for, mental health services. A convenience sample of 194 students (98 men and 96 women) completed the 28-item Japanese version of the General Health Questionnaire and questions regarding reluctance to use and perceived need for mental health services. Participants were in the second to fourth years of undergraduate work and their majors were psychology and technology. Analyses showed that approximately 70% of students were reluctant to use mental health services and this reluctance was less in the group scoring high on anxiety and insomnia than the group scoring lower. Also, perceived need for mental health services was higher for those scoring high on depression. There were some discrepancies in the results and previous studies. Implications of these findings for clinical and preventive practice and for direction for research are discussed.
