“…As bid values were linked to market value, participants may have been more invested in the outcomes of items that they appreciated were worth more. This tendency would echo the sunk cost effect, where emotional and cognitive effort is extended in situations of financial commitment (Zeng, Zhang, et al, 2013 ; Zeng, Zou, & Zhang, 2013b ). This would suggests that P300 component was sensitive to retail value as items of a higher retail price are more salient and engaging.…”

“…An important question is the mechanisms by which social contexts affects cognitive control performance in children. One possibility is that they increase the emotional and motivational aspects of the task, as suggested by greater emotional response than failing in a neutral condition in adults (Zeng, Zou, & Zhang, 2013).…”

Cognitive control is often engaged in social contexts where actions are socially relevant. Yet, little is known about the immediate influence of the social context on childhood cognitive control. To examine whether competition or cooperation can enhance cognitive control, preschool and school-age children completed the AX Continuous Performance Task (AX-CPT) in competitive, cooperative, and neutral contexts. Children made fewer errors, responded faster, and engaged more cognitive effort, as shown by greater pupil dilation, in the competitive and cooperative social contexts relative to the neutral context. Competition and cooperation yielded greater cognitive control engagement but did not change how control was engaged (reactively or proactively). Manipulating the social context can be a powerful tool to support cognitive control in childhood.

“…Although several studies have investigated modulation of bidding behavior on performance of lottery contests or auction games ( Delgado et al, 2008 ; Zeng et al, 2013 ), to the best of our knowledge, few have yet been conducted on neural responses underlying group identity’s effect on bidding behavior in lottery contests. Here, we attempted to advance this issue by analyzing modulatory effects of experimentally created and enhanced group identity on subjects’ brain activity during a lottery contest game ( Tullock, 1980 ).…”

A contest usually involves expenditures, termed “overbidding,” exceeding the theoretical Nash equilibrium. A considerable number of studies have shown that group identity can affect decision-making and competitive behavior, thus providing a new perspective on alleviating the overbidding problem. How group identity influences brain activity when competitors bid in different groups is not yet clear, however. In this study, we implemented group identity manipulation into the lottery contest game and we recorded behavioral and electroencephalography (EEG) data at the same time. Two experimental treatments were conducted to study the effect of group identity on bidding behavior. The event-related potentials (ERP) and event-related oscillations (ERO) techniques were utilized to explore brain activity differences caused by participants’ different bidding behaviors under in-group and out-group conditions. Behavioral results showed that individual expenditure was significantly lower when bidding with in-group opponents than with out-group opponents. Analyses of EEG results revealed that compared to in-group conditions, greater N2 amplitudes and theta power were found under out-group conditions. To extend previous studies, we performed supplementary analysis to explore whether enhancement of group identity had effects on conflict alleviation. Behavioral results indicated that individual expenditure was significantly lower after enhancing group identity when bidding with in-group, and EEG results showed more negative N2 amplitudes, smaller P3 amplitudes and larger theta power after enhancing group identity. Collectively, these findings indicate that group identity modulated bidding behavior, and they provide insight into a mechanism to de-escalate group conflict by enhancing group identity.
