Explicit self-criticism and implicit self-regard: Evaluating self and friend in two cultures

Past research indicates that people in some Asian cultures (e.g., Japan) often explicitly evaluate themselves negatively while implicitly maintaining positive self-evaluations. Two studies provided evidence for the hypothesis that this pattern of explicit and implicit self-evaluations is quite common even outside of Asia, as long as the evaluations are assessed in the context of close, interdependent social relations. Thus, Study 1 applied a modified version of Implicit Association Test to both Japanese and Americans, and showed that the above pattern occurs in both cultures if the self is evaluated vis-à-vis one’s actual friend. Further, Study 2 indicated that when placed in a context that has neither actual nor presumed emotional interdependence, both Japanese and Americans manifest positive self-evaluations at both explicit and implicit levels. Implications for cultural crafting of the self are discussed.     

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).     

Ghrelin stimulates corticotropin-releasing factor and vasopressin gene expression in rat hypothalamic 4B cells

Corticotropin-releasing factor (CRF) and arginine vasopressin (AVP) play a central role in regulating the stress response. In response to stress, CRF and AVP neurons in the hypothalamic paraventricular nucleus secrete the peptides to stimulate the release of adrenocorticotropic hormone from the anterior pituitary. Ghrelin, an endogenous ligand of the growth hormone-releasing peptide receptors (GHSR), has been shown to stimulate the release of CRF and AVP by rat hypothalamic explants. However, little is known about the ability of the ghrelin signaling pathways to activate the CRF and AVP genes in the hypothalamus. In the present study, we examined the direct effect of ghrelin on CRF and AVP gene expression in hypothalamic 4B cells, which show the characteristics of the hypothalamic parvocellular paraventricular nucleus neurons. Cells were transfected with CRF or AVP promoter to examine the activity of each promoter. Ghrelin stimulated the promoter activities and mRNA levels for both CRF and AVP. The involvement of a protein kinase pathway was examined using inhibitors. Protein kinase A and phospholipase C pathways were shown to be involved in ghrelin-induced increases in both CRF and AVP promoter activities. GHSR type 1a (GHSR1a) mRNA levels were also increased by ghrelin, and these ghrelin-induced levels were suppressed by a GHSR1a antagonist. Thus, ghrelin-dependent pathways are involved in the regulation of CRF and AVP gene expression in the hypothalamus: ghrelin, an orexigenic hormone, stimulates CRF, an anorexigenic/anxiogenic factor in the hypothalamus, resulting in hypothalamic-pituitary-adrenal axis activation to stimulate the release of glucocorticoids.     

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.     

What's in a name?: popular names are less common on frontiers

Voluntary settlement on a frontier may promote values of independence. At present, however, researchers know little about the behavioral consequences of this process. In this study, we examined regional variations in baby naming. Because baby naming is an act of considerable personal and familial significance, it reflects prevalent cultural values. In support of the hypothesized link between frontier settlement and independence, we found that babies receive popular names less frequently in western regions of the United States than in its eastern regions (Study 1). The same pattern holds in Canada (Study 2), with popular names being less frequent in western provinces than in eastern provinces. Moreover, popular names are less frequently given to babies in world regions in which Europeans have settled (e.g., Australia, the United States) than in European countries (Study 3). These findings have implications for cross-generational transmission of cultural values.     

Perceiving an object and its context in different cultures: a cultural look at new look

Abstract - In two studies, a newly devised test (framed-line test) was used to examine the hypothesis that individuals engaging in Asian cultures are more capable of incorporating contextual information and those engaging in North American cultures are more capable of ignoring contextual information. On each trial, participants were presented with a square frame, within which was printed a vertical line. Participants were then shown another square frame of the same or different size and asked to draw a line that was identical to the first line in either absolute length ( absolute task ) or proportion to the height of the surrounding frame ( relative task ). The results supported the hypothesis: Whereas Japanese were more accurate in the relative task, Americans were more accurate in the absolute task. Moreover, when engaging in another culture, individuals tended to show the cognitive characteristic common in the host culture.     

Cultural variation in implicit independence: An extension of Kitayama et al. ()

Previous research shows that European Americans are consistently more independent (or less interdependent) than Japanese when implicit indices are used to assess independence (vs. interdependence). The present work extended this evidence by including a novel implicit association test (IAT), as an index of implicit attitude towards independence and interdependence. Consistent with the previous findings, as compared to Japanese, Americans were significantly higher in multiple indices of implicit independence (vs. interdependence) including personal (vs. social) self‐definition, experience of disengaging (vs. engaging) emotions and personal (vs. social) form of happiness. Furthermore, as compared to Japanese, Americans had a significantly more positive implicit attitude towards independence assessed with the IAT. As also observed in the previous research, explicit measures showed inconsistent cross‐cultural patterns. Lastly, we observed little statistical within‐culture coherence among the implicit measures of independence (vs. interdependence), consistent with a view that the implicit indices capture alternative ways for individuals to achieve the cultural mandate of independence or interdependence.     

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.
