This study investigated the effect of a player’s regulatory focus on his/her preference for cooperation and prosociality in a social dilemma situation. After the manipulation of regulatory focus, participants chose cooperation (remaining silent) or defection (betrayal) in simultaneous and sequential Prisoner’s Dilemma (PD) tasks based on a traditional scenario of prison sentence rewards. Participants in the prevention focus condition showed more defection than did those in the promotion focus and the control conditions. In the sequential PD task, a greater number of participants in the prevention focus condition used an egoistic strategy (i.e., consistent defection) as the second movers than did those in the promotion focus and the control conditions, who tended to use a conditional cooperation strategy. These findings suggest that prevention-focused players show a less strong preference for cooperation and behave more selfishly when the pay-off matrix is loss-framed.

近年,企業にとって情報,データは重要な資産となり,特に消費者をターゲットとする企業にとっては,購買履歴をはじめとする個人に関するデータを蓄積,分析し,マーケティングや広告にいかに活かしていくかが重要なテーマとなっている。このような中,個人の関与の下でデータ流通・活用を進めることにより,個人に関するデータの利活用と個人の権利・利益保護のバランスを図ることができる,情報銀行という制度が注目を集めている。そこで本稿では,情報銀行の概要と情報銀行から個人情報等を取得することを検討する事業者における注意点について概説したい。

Interfacial impedance method was applied to evaluate the interface stability of solder joints. Results showed that the surface treatment on rolled copper strongly influenced the solder joint interface structure. The composition and interfacial impedance between rolled copper and solder were also influenced by the surface treatment of the copper. Especially, a correlation was found between the surface treatment and time dependence of the interfacial impedance value. The admittance spectra of interfacial impedance between as-rolled copper and solder showed strain from the semicircular shape, although the plasma ashed copper or thermally oxidized copper showed no such strain over time. The strain probably represents solder joint instability. The interfacial impedance method can be useful for evaluation of the solid metal interface, not only the interface between the liquid and solid.

Today, most Japanese corporations implement a merit pay or pay-for-performance system in order to enhance job performance. This study investigated the effect of pay-for-performance system on employees’ preference for organizational citizenship behavior using the hypothetical Prisoner’s Dilemma. Based on regulatory focus theory (Higgins, 1997), we focused on reward expectation for performance (e.g., promotion) and performance pressure (e.g., fears of failure), both of which presumably affect employees’ approach motivation in a different way. We hypothesized that employees’ reward expectation for performance increases their preference for organizational citizenship behavior while performance pressure decreases it. Three hundred and nineteen Japanese employees completed a take-home questionnaire; however, we only examined 175 of those (126 men and 49 women) who were working under management by objectives. Logistic regression analysis confirmed our hypotheses, suggesting that under pressure employees prioritize their individualized objectives rather than cooperate with others for a common goal. Expectation for reward increased employees’ preference for cooperative behavior when a situation calls for dealing with a coworker’s favor. Furthermore, these results were seen only for employees under pay-for-performance system such that those under the traditional system showed the reverse trend. Future studies should examine situational factors as well as each employee’s approach motivation.
