The Concealed Information Test (CIT) is a scientifically validated technique used in forensic psychophysiology that allows for the detection of concealed memories using physiological response. In a typical CIT, critical items concerning the details of the crime known only to the perpetrator and the investigative authorities are used. However, when the critical items are not known, examiners use Searching CIT (SCIT). The purpose of this study is to examine whether physiological responses depend on the ordinary type or unlimited type of question series. Fifteen undergraduate students were instructed to go to an office room and steal a certain sweet (candy, chocolate, cookie, nuts or gummies) from a table, then hide it somewhere in the room. The skin conductance response (SCR), heart rate and respiration activity were recorded. The examiner first presented the ordinary condition which comprised of only critical and noncritical items, and then conducted a different type of question series including an unlimited item (catch-all item). The results indicated that critical items elicited the SCR significantly stronger than the noncritical items in both question series. It was concluded that the use of a catch-all item didn't affect the differences between critical and noncritical items.

This study examines two viewpoints on acculturation among the ethnic group of Zainichi Koreans, who settled, or whose ancestors settled, in Japan during the Japanese colonial era (1910-1945): the "traditional" view of acculturation (which includes four types of acculturation: assimilation, integration, marginalization, and separation), based on Western academic research, and the "context-specific" or "unattached" view, which conveys a desire for freedom from and a lifestyle or orientation that resists being constrained by pre-determined Korean or Japanese cultures and identities, preferring to identify as "human beings" or "individuals." Through an ANOVA test, our research found that unattachment score was highest in a more integrated group—contrary to our hypothesis that it would be highest in a more marginalized group, who irrespective of the conceptual connection between marginalization and unattachment have a tendency toward integration in their "real lives." These findings can help us understand the daily lives, identities, and perspectives of Zainichi Koreans and other ethnic minorities in Japan.

This study examined infidelity in heterosexual romantic relationships and its effects of gender, attitudes toward infidelity and romantic relationships, and the desire to have an affair. Participants were heterosexual 77 males and 98 females. They were presented with 25 behaviors which were exchanged between males and females and answered their own permissible level of their partners' behaviors and the estimate of their partner's permissible level of their own behaviors in their romantic relationhips. Cluster analysis revealed six clusters: "sexual behaviors", "pleasure behaviors", "companionship and intimate disclosure", "mutual supportive behaviors", "eating and drinking, and giving a present", and "companionate chat". Males' permissible level was higher in sexual behaviors and lower in companionate chat than females'. Their partner's permissible level were higher in sexual behaviors, companionship and intimate disclosure, and mutual supportive behaviors than their own permissible level. Companionate chat was highest and sexual behavior was lowest in both permissible levels. The more permissive attitudes toward infidelity, the stronger desire to have an affair, the less romanticism, and the less romantic power they have, the higher both permissible levels were. The effects on infidelity are discussed.

This research aims to collect experiences of feeling a sexual desire from men during face-to-face interviews to make a sexual desire scale for men (SDS-M) and then examine its reliability and appropriateness. The interviews were carried out with married and unmarried 11 men in their 20s to 40s. In addition, online surveys were conducted among 300 married and unmarried men in their 20s to 40s, using the SDS-M. With the exclusion of data on 39 participants who said they had never experienced sexual intercourse, data on 261 men were put to a factor analysis. As a result, the SDS-M discovered four structural factors: "satisfaction with sex", "satisfaction with masturbation", "desire to seek advice on sexual distress", and "recognition of sexual debility". The discovery verified the reliability of the SDS-M from the aspect of internal consistency and its appropriateness from construct validity. "Desire to seek advice on sexual distress" was stronger among the unmarried than among the married. "Recognition of sexual debility" was conspicuously reported by men in their 40s.

University students may experience emotional problems such as anxiety and depression while seeking employment. These may have a negative effect on the performance accomplishment of job hunting activities. In this study, the effect of irrational beliefs on the stress response and performance accomplishment of seeking employment was examined. The participants included 136 university students. Results revealed that the irrational beliefs of dependence and Helplessness have a negative effect on the stress response while job hunting. Furthermore, these irrational beliefs, through the intervening variable of emotional disturbance, have a negative effect on the performance accomplishment of seeking employment.
