Overshoot rate in a target alignment task depends on the location of the target with reference to the operational boundary of the task. Subjects performed a step tracking task under four conditions combining pursuit and compensatory display modes with joystick and crank control devices. The boundary effect was found when the joystick was used but not the crank, while the display mode had no effect, indicating that subjects moved with respect to a frame of reference based on proprioceptive information. Movements were made according to the postures adopted, irrespective of the concomitant visual consequences. 相似文献

Sex-role stereotyping in English usage 总被引:2,自引:0,他引:2
This study identified children's perception of sex differences in the areas of language usage and occupational roles. The survey instrument used consisted of 28 items. Each item was a pair of statements identical except for one word or phrase. One statement was definitely male or female according to the literature. The other statement was either neutral or one that would be said by the other sex. Subjects were asked to identify statements that would be said by a man on one section of the instrument. They were asked to identify statements that would be said by a woman on the other section. Subjects consisted of 121 children from an inner city school in a low socio-economic area in north central Florida. The children composed five classrooms in grades one through five. One classroom was randomly selected from each grade level. The results indicate that children perceive differences both between the language usage of men and women, and between the conception of occupational roles traditionally assigned to each sex. 相似文献

Two theories of differences among natural language categories in graded membership and strength of class inclusion are contrasted. The two sets of hypotheses tested were: (1) that categories represented by features which many people believe to be necessary would have less graded memberships, and stronger class inclusion, than those represented by features which few people believe to be necessary, and (2) that categories which people believe are represented primarily by intrinsic features (i.e. features that are true of an entity in isolation; see Barr & Caplan, 1987) would have less graded structures, and stronger class inclusion, than those which people believe are represented primarily by extrinsic features (i.e. features representing relations between an entity and other entities). The findings suggest that feature necessity and feature extrinsicity have independent effects on gradedness of category membership and on class inclusion. 相似文献

Two studies investigated the impact of job applicants' facial maturity, gender, and achievement level on hiring recommendations. The results revealed that discrimination based on gender and facial appearance varies with the type of job for which an applicant is being considered. Applicants who were babyfaced or female were favored for jobs requiring qualities of warmth and submission, whereas those who were maturefaced or male were favored for jobs requiring qualities of shrewdness and leadership. These hiring preferences were most pronounced for high achieving applicants. They were also paralleled by stereotypical perceptions of the job- relevant attributes possessed by the applicants, which suggests that the effects of applicants' gender and facial maturity are mediated by the perceived fit between their assumed attributes and the job requirements. Finally, the jobs for which male and maturefaced applicants were favored were those for which high-achieving applicants were also favored, which suggests that female and babyfaced applicants are most apt to be discriminated against when applying for higher status jobs. 相似文献

The aim of the study was to determine if spontaneous play was altered in 2-year-olds born to polysubstance-abusing mothers. The study is part of a longitudinal research project of chronic substance-abusing mothers and their children living in poverty in the inner city of Los Angeles, identified in the hospital at birth by positive urine-toxicology screens, and compared to non-substance-abusing mothers and their children living in the same geographic area, of similar ethnic group and socioeconomic and marital status. The behavior of the 31 target and 21 comparison children in the 16-minute procedure was measured by frequency counts of manipulative, functional, and symbolic acts as well as by ratings of the quality of play. The play of the prenatally drug-exposed children differed from the comparison group by demonstrating significantly more immature play strategies, less sustained attention, more deviant behaviors, and fewer positive social interactions with their caregivers. 相似文献

High levels of infant crying place families at risk for disrupted relationships, parenting stress, and even for child maltreatment. We conducted an evaluation of the Fussy Baby Network® (FBN), a program supporting families struggling with infant crying and related concerns. The study contrasted 29 families who sought help from FBN with 27 families with excessively crying infants who did not seek services. Researchers measured parenting self-efficacy, depression, and stress in each group before and after the intervention. Results from hierarchical multiple regression analysis indicated greater improvements over time in parenting self-efficacy for parents receiving FBN services. Furthermore, the greater improvements in parenting self-efficacy in the intervention group were not directly attributable to reductions in infant crying. These findings provide preliminary evidence that the FBN approach may be effective at boosting the confidence of parents struggling with caring for their infants. Future research with larger samples with baseline equivalence and stronger research designs should explore this intervention further. This study also suggests that interventions for families with excessively crying infants should move beyond the focus of reducing infant crying to a broader strategy of supporting parents and strengthening relationships between parents and their infants to build parenting capacity. 相似文献

Bowen Family Systems Theory predicts that the ability to balance emotional intimacy with one’s partner with one's own sense of autonomy, called differentiation of self, results in stronger relationships. We tested whether this balance manifests in how individuals manage their time spent with and without their partner. Analyses utilized differentiation of self, leisure time balance with and without one's partner, and couple leisure satisfaction to predict dyadic adjustment. Although leisure time balance did not mediate the relationship between differentiation of self and relationship functioning, couple leisure satisfaction was found to partially mediate this relationship. The moderating effect of differentiation was also examined, which demonstrated that differentiation of self buffered the relationship between low couple leisure time satisfaction and relationship adjustment. 相似文献

Alcoholism, or alcohol dependence, is a complex disorder with withdrawal symptoms that are often problematic for those trying to recover from their dependence. As researchers attempt to elucidate the neurobiological underpinnings of alcohol dependence and withdrawal, it is becoming clear that numerous factors, including the hormonal environment, impact the manifestations of this disorder. Of particular interest is the observation that women have fewer and less severe withdrawal symptoms than do men even though they tend to suffer greater physiological harm from excessive alcohol consumption. In this article, the authors present an overview of their understanding of how gonadal and stress hormones interact with alcohol, which results in differential neurobiological responses between males and females. Thus far, data generated from representative animal models have shown significant differences between the sexes in behavioral responses and neuroadaptations to chronic alcohol consumption and withdrawal. Accumulating evidence suggests that treatment of alcoholism, including withdrawal, should be tailored to the patient's gender and hormonal status. 相似文献

A brief self-rating scale, the Assessment of Hyperactivity and Attention (AHA), was developed and validated using a "gold standard" DSM-based semi-structured interview. The sample consisted of 101 smokers (74% male, 73% Caucasian)-38.6% with no DSM-IV ADHD diagnosis, 10.9% with a childhood diagnosis only, and 50.5% with an adult diagnosis (requiring childhood diagnosis as well). The mean age SD was 33.7 9.7; participants smoked a mean of 19.0 5.6 cigarettes/day. Results indicate that the AHA has utility as a screening tool and as a self-report assessment of ADHD with sensitivity of .80, specificity of .60, positive predictive power of .67, negative predictive power of .75, kappa of .40, odds ratio of 6.15, and an area under the curve (receiver operating characteristic analysis) of .79. Given the high rate of ADHD among smokers, the AHA may be useful in identifying smokers who may need more in-depth clinical evaluation for attentional problems. 相似文献

Temperamental characteristics have been related to later externalizing and internalizing behavioral outcomes. To assess the relationship between temperament and the early family environment, we measured infant temperament, pleasure in parenting, and marital happiness via parent report in 99 families with a nonrelative adoptive infant. Perceptions of child temperament were assessed using two subscales of the Infant Behavior Questionnaire (IBQ; Rothbart, 1981). Mothers and fathers who rated their adoptive child as showing more Distress to Limitations (on the IBQ) reported less pleasure in routine parenting activities; this effect was mediated by marital happiness for fathers. Mothers reported less pleasure in parenting with infants perceived to be more temperamentally fearful (on the IBQ). The bidirectional relationship between temperamental characteristics and pleasure in parenting is discussed. © 2001 Michigan Association for Infant Mental Health. 相似文献
