The intergenerational transmission of ethnic essentialism: how parents talk counts the most

The present study analyzed the role of parents as potential sources of children's essentialist beliefs about ethnicity. We tested 76 parent–child (5‐year‐olds) dyads of Jewish Israeli parents from three social groups, defined by the kindergartens children attended: national religious, secular, or Jewish‐Arab integrated. We assessed parents' and children's beliefs, and parents' usage of ethnic attitudinal and categorization markers in a book‐reading activity. Overall, national religious parents manifested the strongest ethnic essentialism and endorsement of anti‐negotiations with Palestinians, and were the most likely to express negative attitudes and mark ethnic categories in their conversations with their children. Moreover, regression analyses revealed that ethnic categorization in parents' speech was the most reliable predictor of children's ethnic essentialism. Ethnic essentialism is transmitted to children not via explicit communication of intergroup beliefs or attitudes, but rather via the sheer marking of categories in ways that resonate with children's own intuitive ways of conceptualizing the social world.     

Collective trauma and post-traumatic symptoms in the biblical narrative of ancient Israel

According to the biblical books of Exodus and Numbers, the early Israelites suffered recurrent plagues and other events which comprise significant collective trauma coinciding with their physical and spiritual birth as a people. These ancient narratives reflect a fledgling people's coping with high levels of transitional stress, multiple crises, and significant losses attendant upon slavery and genocide. Inspection of the text also reveals signs of collective post-traumatic reactions among the Israelites. Relevant psychological perspectives on stress, loss, and trauma can therefore usefully illuminate specific biblical events. Trauma may well be implicated in the etiology of certain stringent biblical commandments, including “the ban” and related severe restrictions against Israelite intermarriage. The Bible may also contain insights bearing upon social action aimed at preventing or coping with epidemics and for overcoming psychological trauma, of relevance to a modern positive community psychology.     

Two operations for "ratios" and "differences" of distances on the mental map

Ss judged "ratios of distances" and "differences of distances" between pairs of U.S. cities. Results fit the theory that Ss used two comparison processes as instructed. A ratio scale of distances between cities was constructed from the 2 rank orders. From this scale, an interval scale of the city locations on an east-west continuum was derived. This scale agrees with the subtractive model fit to "ratios" and "differences" of easterliness and westerliness, and it also agrees with multidimensional scaling of judged distances between cities. These findings are consistent with the theory that Ss use subtraction when instructed to judge either "ratios" or "differences," but that they can use both ratio and difference operations when the stimuli (in this case, distances) constitute a ratio scale on the subjective continuum.     

VIOLATIONS OF BRANCH INDEPENDENCE IN JUDGMENTS OF THE VALUE OF GAMBLES

Abstract —Branch independence is weaker than Savage's "sure thing" principle. It requires that judgments of gambles with a common outcome produced by the same probability-event must not reverse order when that common outcome is changed. Subjects judged 168 gambles from viewpoints of both buyer (highest buying price) and in both viewpoints. Violations also changed systematically between viewpoints, consistent with the theory that viewpoint affects configural weighting but not the utility function. Violations of branch independence were opposite those predicted by the model of cumulative prospect theory. The middle of three equally likely outcomes received the most weight in the seller's viewpoint. In the buyer's, lower outcomes received greater weights. In both viewpoints, the ratio of weights of the middle outcome to the highest outcome exceeded the ratio of weights of the lowest outcome to the middle outcome.     

A theory of perceived risk and attractiveness

People judged both the attractiveness and risk of lotteries to win or lose money. The lotteries were designed to test whether risk and attractiveness judgments show systematic deviations from the simple sum of probability-by-utility-products analogous to (S)EU theory. Our results led to an alternative combination rule for probability and outcome information, with a relative weight averaging component and a configural (i.e., sign- or rank-dependent) probability weighting component. Ratings of risk and attractiveness were negatively correlated, but the two tasks showed systematic differences in the rank order of judgments. Both judgments could be fit by the same configural relative weight averaging model, but with different parameters (especially the sign-dependent probability weighting functions). Risk judgments were more sensitive to the probability of losses and zero outcomes compared to attractiveness judgments, which were more sensitive to the probability of gains. There were individual differences on the extent of this difference in probability weights between risk and attractiveness judgments.     

Measuring the importance of cues in judgment for individuals: Subjective theories of IQ as a function of heredity and environment

To measure the relative subjective importance attached to heredity and environment, undergraduates, graduate students, and faculty were asked to predict the IQ scores of hypothetical adopted children based on the IQs of the biological mother and father, the IQs of the adoptive parents, and the socioeconomic status of the adoptive parents. Intuitive predictions of IQ were inconsistent with additive, multiple regression models. Rather, the data for individual subjects were consistent with a configural-weight averaging model. Weights derived from this model were correlated with ratings of the relative importance of cues. Judges who rated the environment more important not only had greater weights for the environmental variables, but also placed greater weight on high rather than low scores. The judges who rated heredity more important than environment had greater estimated weights for heredity information and for lower-valued information. Results were thus consistent with the hypothesis that model-derived relative weights and individuals ratings of the relative importance of cues are both measures of the importance that individuals attach to these cues.     

Combining information from sources that vary in credibility

Models describing the role of source credibility in information integration were tested in two experiments. In the first experiment, subjects estimated the value of used cars based on two cues: blue book value and an estimate provided by one of three friends who examined the car. The three sources were described as differing in mechanical expertise. In the second experiment, subjects rated the likeableness of persons described by either one or two adjectives, each adjective contributed by a different source. The sources differed with respect to the length of their acquaintance with the person to be rated. In both experiments, credibility of the source magnified the impact of the information he provided. Further, this multiplicative effect of a source was inversely related to the credibility of the other source, in violation of additive or constant-weight averaging models, but consistent with a relative-weight averaging model.     

Preschoolers' inferences about gender and emotion: The mediation of emotionality stereotypes

This study examined childrens' stereotypes about sex differences in emotionality. Thirty preschoolers were presented with hypothetical emotional situations and asked to indicate the gender of the expressor and reasons for their choice. Although fear was consistently associated with females, gender attribution was situation specific for anger and happiness. Examination of preschoolers' explanations for gender attributions revealed that females made greater use of sex-role and imagery categories than did males. Furthermore, a significant age difference in the use of categorical and noncategorical responses was reported, with younger children making a greater number of noncategorical explanations. Children who used imagery to mediate gender choice relied primarily on hair color and length as gender-specific cues.     

Contextual effects in social judgment

Judges were asked to evaluate the overall performance of hypothetical students, given their scores on two examinations. The distribution of total scores was manipulated in order to investigate the loci of contextual effects. The interaction between the two exams was reversed by manipulation of the distribution. When the distribution of total scores was positively skewed, judgments showed a convergent interaction as a function of the two exams; when the distribution was negatively skewed, the interaction was divergent. The data were consistent with the hypothesis that the distribution of total scores affects only the transformation from integrated impressions to overt responses. This transformation (judgment function) was well-described by an extension of range-frequency theory. The finding that the interaction can be manipulated by changing the stimulus distribution has methodological implications for the popular interpretation of interactions or lack thereof. A good model may be improperly rejected or a bad one improperly retained through lack of attention to contextual effects.
