Asymmetrical hand function was examined in the context of expert sports performance: hitting in professional baseball. An archival study was conducted to examine the batting performance of all Major League Baseball players from 1871 to 1992, focusing on those who batted left (n = 1,059) to neutralize the game asymmetry. Among them, left-handers (n = 421) were more likely to hit with power and to strike out than right-handers (n = 638). One possible account, based on the idea of hand dominance and an analogy to tennis, is that batting left involves a double-handed forehand for left-handers and a weaker and more reliable double-handed backhand for right-handers. The results are also interpretable in the light of Y. Guiard's (1987) kinematic chain model of a between-hands asymmetrical division of labor, which provides a detailed account of why left batting is optimal for left-handers. 相似文献

Verbal and spatial span, articulation and tapping rate, and verbal and spatial speed-of-search tasks were administered to sixty 6- to 12-year-olds. A variance-partitioning procedure was then used to identify age-related and age-invariant components of variance in span. Outcomes were very similar for verbal and spatial span, in particular, (i) most of the age-related variance was shared by the speed-of-search and rate predictors, (ii) articulation rate provided an age-independent contribution, (iii) changing-state versions of predictor tasks did not account for variance over steady-state versions, and (iv) predictors of the same modality as the span task did not outperform predictors of the other modality. We conclude that verbal and spatial short-term memory appear to rely on similar processes when serial recall is required and that developments in span are closely tied to increases in processing speed. 相似文献

This study tested the hypothesis that the sonority of phonemes (a sound's relative loudness compared to other sounds with the same length, stress, and pitch) influences children's segmentation of syllable constituents. Two groups of children, first graders and preschoolers, were assessed for their awareness of phonemes in coda and onset positions, respectively, using different phoneme segmentation tasks. Although the trends for the first graders were more robust than the trends for the preschoolers, phoneme segmentation in the two groups correlated with the sonority levels of phonemes, regardless of phoneme position or task. These results, consistent with prior studies of adults, suggest that perceptual properties, such as sonority levels, greatly influence the development of phoneme awareness. 相似文献

"I" Value Freedom, But "We" Value Relationships: Self-Construal Priming Mirrors Cultural Differences in Judgment 总被引:2,自引:0,他引:2
The distinction between relatively independent versus interdependent self-construals has been strongly associated with several important cultural differences in social behavior. The current studies examined the causal role of self-construal by investigating whether priming independent or interdependent self-construals within a culture could result in differences in psychological worldview that mirror those traditionally found between cultures. In Experiment 1, European-American participants primed with interdependence displayed shifts toward more collectivist social values and judgments that were mediated by corresponding shifts in self-construal. In Experiment 2, this effect was extended by priming students from the United States and Hong Kong with primes that were consistent and inconsistent with their predominant cultural worldview. Students who received the inconsistent primes were more strongly affected than those who received the consistent primes, and thus shifted self-construal, and corresponding values, to a greater degree. 相似文献

Self esteem and body esteem were examined in a group of 35 relapsing-remitting multiple sclerosis (MS) patients using the Body Esteem Scale (BES) and the Eysenck Self Esteem Scale (ESES) and compared to age and sex matched normal controls. There were 23 females and 12 males in the MS patient's group; average age 38.9 years (range: 22-52). All participants completed the self-rated BES evaluating the following subscales: females - sexual attractiveness, physical condition and weight concern; males - physical attractiveness, physical condition and upper body strength. In addition all participants were scored, following a semi-structured interview, on the ESES. Psychiatric co-morbidity was excluded using a semi-structured interview by the consulting psychiatrist. All evaluations were carried out during the remitting phase. Statistical analysis, comparing patients to healthy controls, demonstrated lowered self-rating of the physical condition (males < 0.05, females < 0.001). On the other hand, no significant differences were found in the physical (male) or sexual (female)?attractiveness subscales. The mean ESES score in the patients group was 23.2 ± 4.0, slightly above the reported average. The controls mean ESES was 28.4 ± 3.6, (P < 0.05). No correlation was found between self and body esteem amongst M.S. patients. This study emphasizes impaired perception of body esteem in multiple sclerosis patients even in remission. The preservation of physical and sexual attractiveness may be related to the non-disfiguring nature of the disease. Preservation of self-esteem in MS patients suggests that body-esteem should be the focus of supportive treatment. 相似文献

The blood coagulation time as an integral sign of human homeostasis is revealed to be influenced by conscious or unconscious olfactory stimuli through autonomic mechanisms. The hemostasis of subjects with predominance of sympathetic activity is more sensitive to the olfactory stimuli than that of subjects with vagal prevalence. The effects of the olfactory stimuli upon hemostasis in humans support the viewpoint that simultaneous information and physico-chemical processes act together in parallel to play and important role in life activities of human organism (Simonov, 1981; Sudakov, 1995). Emotions, therefore, are essential in the transfer of information from the environment (Anokhin, 1966; Miltner et al., 1994). It is not excluded that even very weak stimuli which are subthreshold for conscious perception might be informational for the organism as those engaging emotional response. 相似文献

An interactive model of perfectionism, perceived weight status, and self-esteem was tested on 342 female undergraduates to predict bulimic symptoms. Using a longitudinal design, the authors tested the model on data collected at 2 points: the spring of participants' senior year of high school and during participants' first year of college. The authors hypothesized and found that self-esteem moderates the interaction between perfectionism and perceived weight status in predicting bulimic symptoms. Women who are high in perfectionism and who consider themselves overweight exhibit bulimic symptoms only if they have low self-esteem (i.e., if they doubt they can attain their high body standards). High self-esteem women with the same diathesis-stress conditions are less likely to exhibit bulimic symptoms. These findings clarify the role of perfectionism in bulimic symptomatology. 相似文献

This study compared scores on future time perspective of 50 female prison inmates who were participating in a vocational training program within the Julia Tutwiler Prison. There was no control group. Zimbardo's measure of future time perspective, administered a year earlier, was associated with success or failure in the program. Associations of future time perspectives with education, age, and ethnicity were investigated. An analysis of covariance between the 21 graduates and 16 dropouts while controlling for education was significant. Despite the incomplete design, some implications are of interest. 相似文献

The extent to which adherence to one demand of the diabetic treatment regimen is related to adherence to other regimen demands was explored in a sample of 227 diabetic patients. Adherence to weight control, urine/blood testing, medication taking, symptom reporting, and safety demands was assessed using a variety of methods: (a) patients' report in relation to physician's criteria, (b) patients' report in relation to their own understanding of those criteria, (c) significant others' reports, (d) nurses' ratings, and (e) physicians' ratings. Based on attribution theory, it was proposed that informed others would view patients as more consistent than patients themselves did. Separate intercorrelation matrices were created for each method. The correlations, however, were uniformly low (most rs less than .25) and mean correlations did not differ significantly between matrices. The relative independence of adherence to different demands of the diabetic regimen has important implications for the conceptualization and measurement of treatment adherence. 相似文献
