Necessary versus sufficient causal schemata: Attributions for achievement in difficult and easy tasks

Previous research on Kelley's schemata for multiple sufficient and multiple necessary causes has failed to examine the hypothesis that a schema influences both predictions of an event and attributions of its causes. This research examined the effects of the difficulty of a hypothetical exam on predictions of exam grades, and on attributions of ability and effort. Exam difficulty influenced both the pattern of judgments of grades and reported beliefs in multiple necessary versus multiple sufficient causes. Contrary to the predictions of the schema theory, exam difficulty had little influence on the pattern of attributions of ability and effort. Kelley's concept of a causal schema is reinterpreted in terms of current views of human judgment, and the possible implications of the data for the interpretations of a causal schema are examined. The results question the assumption that attributions are based on beliefs about how causes combine to determine an effect, and suggest further research on the relationship between predictions and attributions.     

Ingroup bias as a function of salience,relevance, and status: An integration

This paper reports the results of a meta-analytic integration of the results of 137 tests of the ingroup bias hypothesis. Overall, the ingroup bias effect was highly significant and of moderate magnitude. Several theoretically informative determinants of the ingroup bias effect were established. This ingroup bias effect was significantly stronger when the ingroup was made salient (by virtue of proportionate size and by virtue of reality of the group categorization). A significant interaction between the reality of the group categorization and the relative status of the ingroup revealed a slight decrease in the ingroup bias effect as a function of status in real groups, and a significant increase in the ingroup bias effect as a function of status in artificial groups. Finally, an interaction between item relevance and ingroup status was observed, such that higher status groups exhibited more ingroup bias on more relevant attributes, whereas lower status groups exhibited more ingroup bias on less relevant attributes. Discussion considers the implications of these results for current theory and future research involving the ingroup bias effect.     

The use of the large-scale integrated sensor (LSI) to estimate energy expenditure

The relationship between activity counts from the large-scale integrated sensor (LSI), placed at the hip and ankle, and heart rate-estimated energy expenditure was examined in three nonobese males during three conditions: normal morning activities, a 1-mi walk, and a 2-mi walk. Results showed that estimated caloric expenditure was related to activity counts for both monitoring placements, with correlations between counts and energy expenditure exceedingr=.90. These results show that energy expenditure in the activities sampled can be reliably estimated using activity monitors.This research was supported in part by a grant provided by The John D. and Catherine T.

A Comparative Study in the levels of Human Values: People's Republic of China, Singapore, Taiwan, and the United States

This study investigates the relative importance of human values at four levels: (a) global, (b) national, (c) family, and (d) individual, among university students from four countries – the United States (137 females, 78 males, one unspecified), the People's Republic of China (66 females, 170 males, one unspecified), Taiwan (156 females, 101 males), and Singapore (148 females, 119 males). Students rated the importance of passing on the 68 items in the Child Socialization Value Survey to their children or to future generations. Principal Components Analysis was performed on the pooled sample of student responses and revealed a five-factor solution described by: universalism, family, nationalism, prestige, and autonomy. This study demonstrates that the values endorsed by samples of Chinese across different geopolitical backgrounds are not consistent.     

Memory for impasses during problem solving

Three experiments were conducted to investigate the relative memorability of solved versus unsolved problems in long-term memory. In each experiment, subjects worked on a set of potentially solvable word problems, with the time spent on each problem held constant. Problem memorability was then measured with a free-recall task. In Experiment 1, in which a majority of problems were solved, unsolved problems were better remembered. In Experiments 2 and 3, we expanded on these results by manipulating problem difficulty and thus the ratio of solved to unsolved problems. When unsolved problems were as frequent as or more frequent than solved problems, no memory differences were found. Across all three experiments, the ratio of solved to unsolved problems was found to be a significant predictor of unsolved-problem memorability, but was not significantly related to the memorability of solved problems. The results illustrate that when impasses in problem solving are infrequent, they are more available in memory than are solved problems. It is speculated that this memory phenomenon may facilitate the recognition of opportunities to return to problems that have been terminated short of solution.     

The Baby Blanket or the Briefcase: The Impact of Evangelical Gender Role Ideologies on Career and Mothering Aspirations of Female Evangelical College Students

This study examines the relationship between the Evangelical gender role ideologies termed Complementarianism and Egalitarianism and mothering and career aspirations among Evangelical female college students. We surveyed 134 women from two colleges in the United States, one in the Midwest and one in the South. Using a cross-sectional, self-report survey design, we examined the interaction between career aspirations and mothering aspirations as well as the impact of Evangelical gender role ideologies on both types of aspirations. Results indicated that career and home aspirations were negatively correlated. Mothering aspirations were shown to be significantly affected by conservative gender role ideology. These findings suggest that aspirations for one’s mothering role may be influenced by ideological positions.     

Judicial gatekeeping and the social construction of the admissibility of expert testimony

Content analysis of 192 U.S. District Court cases was conducted to investigate judges' evaluations of expert characteristics and evidence characteristics for toxicology, psychological/psychiatric, and damages testimony. Judges evaluated more expert characteristics, but not more evidence characteristics, as the number of months post-Daubert increased (Hypotheses 1 and 2). More evidence characteristics were evaluated when evidence was quantitatively rather than qualitatively based (Hypothesis 3). The greatest number of evidence characteristics examined was for toxicology evidence (Hypothesis 4). Fewer expert characteristics were evaluated for admissible evidence, but more evidence characteristics were evaluated for inadmissible evidence (Hypothesis 5). All analyses were significant at .05. Implications for judges, attorneys, and experts are discussed.     

Junior football players' classification of runners as their teammates from 400-msec. video clips

It was hypothesized that a specialized gait recognition skill enables humans to distinguish the gait of familiar from unfamiliar individuals, and that this may have relevance in team sports. Runners seen for less than half a second can be classified as teammates or not by adult players, so it may be asked whether this skill would also be demonstrated by young team players. In the current study, junior football players (M age = 10.0 yr., SD = 0.8, N = 13) viewed 400-msec. video clips of runners sprinting past a fixed forward facing digital video camera and similarly showed teammate recognition scores significantly above chance. Given the variation among the junior players in this skill, it seems possible for researchers to assess whether improvement can be obtained with structured training for young team players, where running teammates are seen in peripheral vision during training drills.
