Culture and context: East Asian American and European American differences in P3 event-related potentials and self-construal

Research has demonstrated differences in social and cognitive processes between East Asians and European Americans. Whereas East Asians have been characterized as being more sensitive to situational context and attending more to the perceptual field, European Americans have been characterized as being more focused on the object and being more field independent. The goal of the present experiment was to investigate differences in neural responses to target objects and stimulus context between East Asian Americans and European Americans using a three-stimulus novelty P3 event-related potential design. As hypothesized, European Americans displayed relatively greater target P3 amplitudes, indexing attention to target events, whereas East Asian Americans displayed relatively greater novelty P3 amplitudes, indexing attention to contextually deviant events. Furthermore, the authors found that interdependent self-construal mediated the relationship between culture and the novelty P3. These findings identify a specific pattern of neural activity associated with established cultural differences in contextual sensitivity.     

Perception of emergent configurations in humans (Homo sapiens) and chimpanzees (Pan troglodytes)

We examined the perceptions of emergent configurations in humans and chimpanzees using a target-localization task. The stimulus display consisted of a target placed among multiple identical distractors. The target and distractors were presented either solely, within congruent contexts in which salient configurations emerge, or within incongruent contexts in which salient configurations do not emerge. We found that congruent contexts had similar facilitative effects on target localization by humans and chimpanzees, whereas similar disruptive effects emerged when the stimuli were presented within incongruent contexts. When display size was manipulated, targets under the congruent-context condition were localized in a parallel manner, but those under the no-context and incongruent-context conditions were localized in a serial manner by both species. These results suggest that both humans and chimpanzees perceive emergent configurations when targets and distractors are presented within certain congruent contexts and that they process such emergent configurations preattentively.     

Counteractive control over temptations: Promoting resistance through enhanced perception of conflict and goal value

The present research explored people’s everyday practice of counteractive control. Experience sampling was used to test our prediction that strong temptations would promote self-control. Participants were 237 Japanese citizens with ages ranging from 18 to 69. Results indicated that perceived temptation prompted stronger resistance and restraint of behaviors, compared to those cases where no conflict was perceived. In addition, multilevel path analysis revealed the underlying process such that (a) a strong desire toward temptation intensified perception of conflict; (b) perceived conflict bolstered the value of goals that were in disagreement with the temptation; and (c) highly valued goals promoted self-control (i.e., stronger resistance and hence less yielding to temptation).     

Identification with a wrongful subgroup and the feeling of collective guilt

The present study examined the relationship between group identification and the feeling of collective guilt. This study argued that identification with a subgroup of one's ingroup (subgroup identification) would predict the feeling of collective guilt better than identification with the whole ingroup (whole‐group identification). To manipulate the level of subgroup identification, we instructed participants to imagine the presence of a close friend (vs a friend of one's close friend) in a fictitious subgroup. In Experiment 1, we predicted and found that high subgroup identifiers experienced less collective guilt compared to low subgroup identifiers, regardless of their degree of whole‐group identification. In contrast, the results from Experiment 2 indicated that when the presence of the third party was made salient, high subgroup identifiers experienced more collective guilt in comparison to low subgroup identifiers. The importance of interpersonal connections for collective responsibility and the facilitating role of the third party for reconciliation of the intergroup conflicts are discussed.     

Situation selection is a particularly effective emotion regulation strategy for people who need help regulating their emotions

Situation selection involves choosing situations based on their likely emotional impact and may be less cognitively taxing or challenging to implement compared to other strategies for regulating emotion, which require people to regulate their emotions “in the moment”; we thus predicted that individuals who chronically experience intense emotions or who are not particularly competent at employing other emotion regulation strategies would be especially likely to benefit from situation selection. Consistent with this idea, we found that the use of situation selection interacted with individual differences in emotional reactivity and competence at emotion regulation to predict emotional outcomes in both a correlational (Study 1; N?=?301) and an experimental field study (Study 2; N?=?125). Taken together, the findings suggest that situation selection is an effective strategy for regulating emotions, especially for individuals who otherwise struggle to do so.     

Increasing toughness by promoting discontinuous precipitation in Cu–Ni–Si alloys

The influence of precipitation morphology, including continuous precipitation (CP) and discontinuous precipitation (DP), on the mechanical behaviour of Cu–Ni–Si alloys was studied. The Cu–6Ni–1.5Si (in wt%) alloy was solution heat treated at 980 °C for 2 h and aged at 500 °C for 0.5 and 3 h to produce CP and DP structures. The DP specimen showed an abnormal increase in tensile ductility with increasing strain rate, unlike the CP counterpart. The impact toughness of the DP specimen was 1.6 times greater than that of CP specimen. The fracture mode in DP specimen was mostly dimpled rupture, while the mixed mode of cleavage fracture and dimpled rupture was noted on the CP specimen.     

Self-construal, mental distress, and family relations: a mediated moderation analysis with Asian American adolescents

The interactive effects between interdependent and independent self-construal on family cohesion and mental distress were examined. Survey responses from 153 Asian American high school students supported the hypothesized moderation of interdependence by independence on family cohesion, which was found to further mediate the relationship between self-construal and mental distress. Specifically, interdependence was positively associated with family cohesion when independence was high and negatively associated with family cohesion when independence was low. Accounting for the mediator effects of family cohesion, mental distress was positively associated with interdependence and more so for those low on independence than those high on independence. The benefits of biculturalism and research implications for the bidimensional conceptualization of self-construal for ethnic minority populations are discussed.     

What they think of us: Meta-beliefs and solidarity-based collective action among the advantaged

Collective action researchers have recently started investigating solidarity-based collective action by advantaged groups. This literature, however, has overlooked intergroup meta-beliefs (MBs, i.e., beliefs about the outgroup's beliefs), which we argue are crucial, since solidarity inherently involves protesting for the outgroup. In the context of racial inequality in the U.S., we focused on three MBs White Americans could hold: responsibility, inactivity, and allyship. In two studies (N_total = 648), we found that inactive and responsible MBs predicted higher collective action tendencies among low White identifiers via guilt and obligation to act. Conversely, we found that both predicted lower collective action tendencies among high White identifiers, via perceived unfairness. Finally, we found that ally MB was positively associated with collective action tendencies, regardless of identification. We highlight the importance of the meta-perspective in understanding solidarity-based collective action, and discuss conceptual and practical implications of these findings.
