"In-group love" and "out-group hate" as motives for individual participation in intergroup conflict: a new game paradigm.
What motivates individual self-sacrificial behavior in intergroup conflicts? Is it the altruistic desire to help the in-group or the aggressive drive to hurt the out-group? This article introduces a new game paradigm, the intergroup prisoner's dilemma-maximizing difference (IPD-MD) game, designed specifically to distinguish between these two motives. The game involves two groups. Each group member is given a monetary endowment and can decide how much of it to contribute. ⋯ An experiment demonstrated that contributions in the IPD-MD game are made almost exclusively to the cooperative, within-group pool. Moreover, preplay intragroup communication increases intragroup cooperation, but not intergroup competition. These results are compared with those observed in the intergroup prisoner's dilemma game, in which group members' contributions are restricted to the competitive, between-group pool.

The threat of appearing prejudiced and race-based attentional biases.
The current work tested whether external motivation to respond without prejudice toward Blacks is associated with biased patterns of selective attention that reflect a threat response to Black individuals. In a dot-probe attentional bias paradigm, White participants with low and high external motivation to respond without prejudice toward Blacks (i.e., low-EM and high-EM individuals, respectively) were presented with pairs of White and Black male faces that bore either neutral or happy facial expressions; on each trial, the faces were displayed for either 30 ms or 450 ms. ⋯ These attentional biases were eliminated, however, when the faces displayed happy expressions. These findings suggest that high levels of external motivation to avoid prejudice result in anxious arousal in response to Black individuals, and that this response affects even basic attentional processes.

People consider the mental states of other people to understand their actions. We evaluated whether such perspective taking is culture dependent. People in collectivistic cultures (e.g., China) are said to have interdependent selves, whereas people in individualistic cultures (e.g., the United States) are said to have independent selves. ⋯ Moreover, Americans often completely failed to take the perspective of their partner, whereas Chinese almost never did. We conclude that cultural patterns of interdependence focus attention on the other, causing Chinese to be better perspective takers than Americans. Although members of both cultures are able to distinguish between their perspective and another person's perspective, cultural patterns afford Chinese the effective use of this ability to interpret other people's actions.

Randomized Controlled TrialHeart rate variability reflects self-regulatory strength, effort, and fatigue.
Experimental research reliably demonstrates that self-regulatory deficits are a consequence of prior self-regulatory effort. However, in naturalistic settings, although people know that they are sometimes vulnerable to saying, eating, or doing the wrong thing, they cannot accurately gauge their capacity to self-regulate at any given time. ⋯ The experimental manipulation and higher HRV at baseline independently predicted persistence at a subsequent anagram task. HRV appears to index self-regulatory strength and effort, making it possible to study these phenomena in the field as well as the lab.
