Effect of traditional judo training on aggressiveness among young boys

This study assessed the effect of one year of traditional judo training on aggressiveness among young boys. 27 primary school pupils and 28 judo students were asked to complete the Buss-Perry Aggression Questionnaire at two times 1 year apart. Analysis showed that judoka were more aggressive (had higher scores on Total Aggression, Verbal Aggression, and Anger) than the control group after one year of training, even if variations in aggressiveness were not significant. So, results do not support the view that judo training leads to less aggressiveness in a sample of children this young.     

Race and self-esteem: meta-analyses comparing whites,blacks, Hispanics,Asians, and American Indians and comment on Gray-Little and Hafdahl (2000)

These meta-analyses examine race differences in self-esteem among 712 datapoints. Blacks scored higher than Whites on self-esteem measures (d = 0.19), but Whites scored higher than other racial minority groups, including Hispanics (d = -0.09), Asians (d = -0.30), and American Indians (d = -0.21). Most of these differences were smallest in childhood and grew larger with age. Blacks' self-esteem increased over time relative to Whites', with the Black advantage not appearing until the 1980s. Black and Hispanic samples scored higher on measures without an academic self-esteem subscale. Relative to Whites, minority males had lower self-esteem than did minority females, and Black and Hispanic self-esteem was higher in groups with high socioeconomic status. The results are most consistent with a cultural interpretation of racial differences in self-esteem.     

Culture and judgment of causal relevance

The authors hypothesized that because the causal theories of East Asians were more holistic and complex than those of Americans, the amount of information considered before making a final attribution would be larger for East Asians than for Americans. This hypothesis was supported through 4 studies. When participants attempted to explain a deviant behavior (Study 1) or a prosocial behavior (Study 2), Korean participants took into consideration a greater amount of information than did either American or Asian American participants. Study 3 replicated the findings of Studies 1 and 2 within each culture. Finally, Study 4 established a link between the present findings and past research on culture and attribution. Namely, Study 4 found that Koreans made more external attributions than Americans because Koreans considered more information than did Americans.     

Topics of marital disagreement among African-American and Euro-American newlyweds

To see what issues couples most and least often reported as topics of marital disagreement, survey data were analyzed for 113 African-American and 131 Euro-American couples reporting in the first and third years of marriage. Friedman tests showed that in both the first and third years of marriage, money was most often reported as a topic of marital disagreement; tensions about leisure, each spouse's family of origin. and children were reported significantly less often; and tensions about religion were reported least often. Findings were very similar for African Americans and Euro-Americans, and for husbands and wives. Overall, findings show considerable stability in the relative frequency with which specific topics reportedly evoke tension early in marriage.     

Visual recalibration of auditory speech identification: a McGurk aftereffect

The kinds of aftereffects, indicative of cross-modal recalibration, that are observed after exposure to spatially incongruent inputs from different sensory modalities have not been demonstrated so far for identity incongruence. We show that exposure to incongruent audiovisual speech (producing the well-known McGurk effect) can recalibrate auditory speech identification. In Experiment 1, exposure to an ambiguous sound intermediate between /aba/ and /ada/ dubbed onto a video of a face articulating either /aba/ or /ada/ increased the proportion of /aba/ or /ada/ responses, respectively, during subsequent sound identification trials. Experiment 2 demonstrated the same recalibration effect or the opposite one, fewer /aba/ or /ada/ responses, revealing selective speech adaptation, depending on whether the ambiguous sound or a congruent nonambiguous one was used during exposure. In separate forced-choice identification trials, bimodal stimulus pairs producing these contrasting effects were identically categorized, which makes a role of postperceptual factors in the generation of the effects unlikely.     

Cultural psychology of surprise: holistic theories and recognition of contradiction

The authors tested the hypothesis that East Asians, because of their holistic reasoning, take contradiction and inconsistency for granted and consequently are less likely than Americans to experience surprise. Studies 1 and 2 showed that Korean participants displayed less surprise and greater hindsight bias than American participants did when a target's behavior contradicted their expectations. Studies 3 and 4 further demonstrated that even when contradiction was created in highly explicit ways, Korean participants experienced little surprise, whereas American participants reported substantial surprise. We discuss the implications of these findings for various issues, including the psychology of conviction, cognitive dissonance, and the development of science.
