The Sports Behavior Checklist (SBC) is subjected to a principal components analysis, and subscales are correlated with subscales of the Conners' Revised Parent Form and the Social Skills Rating System. Both of these analyses are conducted to determine the construct validity of the instrument. A subsample of lower socioeconomic status individuals is used to compare ADHD and control group differences on the subscales of the SBC. The authors find that a six-factor solution, as proposed by the original authors, accounted for 71.5% of the variance. As hypothesized, subscales on the SBC are low to moderately related to subscales on the anchor measures. Significant group differences are found on the Aggression, Emotional Reactivity, and Injury subscales. Implications and limitations are discussed. 相似文献

Neuropsychological Aspects of Pediatric Sickle Cell Disease 总被引:2,自引:0,他引:2
Sickle cell disease (SCD), a class of genetic disorders characterized by abnormal, sickled red blood cells, is a chronic illness that results in progressive cerebrovascular disease. Neurocognitive sequelae of clinically apparent cerebrovascular accidents in children with SCD are characterized by pervasive impairments, including decrements in general intellectual functioning, language and verbal abilities, visual-motor and visual-spatial processing, memory, academic achievement, and processing of subtle prosodic information. In contrast, subtle neurocognitive deficits in the areas of attention and concentration, executive function, and visual-motor speed and coordination appear to be associated with silent infarcts that are not necessarily detected on physical examination. Investigation of the disease course and associated neurocognitive sequelae suggest a disease-specific model of neuropsychological impairment. Recommendations are made for clinical and research efforts in the field of pediatric neuropsychology. 相似文献

The present research investigated whether competition influences children's artistic creativity and intrinsic motivation toward an art activity. Study 1 tested the hypothesis that boys' creativity would be enhanced by competition, while girls' creativity would be undermined. Fifty children (aged 6–10) made paper collages in one of two conditions; half competed for prizes and half did not. Results supported our hypotheses, and further showed that when children self-segregated by gender, the impact of competition was much more pronounced. Study 2 was designed to clarify the unexpected gender-segregation finding from Study 1. The Children's Sex Role Inventory [Boldizar, J.P. (1991). Assessing sex typing and androgyny in children: the Children's Sex Role Inventory. Developmental Psychology, 27, 505–515] was administered to 143 children (aged 6–11). One week later, these children made paper collages in one of four conditions; in addition to manipulating competition, assigned seating ensured that half of children were segregated by gender and half were not. Following the collage activity, an intrinsic and extrinsic motivation questionnaire was administered. Masculine children reported higher levels of intrinsic motivation when competing and when segregated by gender; they also reported higher levels of extrinsic motivation, especially when segregated by gender. These findings demonstrate that gender role is an important factor in determining children's responses to competition. 相似文献

This is a critical look at the question of design from a feminist theological perspective. The author analyzes James Moore's 1995 Zygon article, "Cosmology and Theology: The Reemergence of Patriarchy." Then she looks at the relationship between science and religion from a feminist perspective, focusing on the kyriarchal nature of theology itself in light of the myriad power issues at hand. Finally, she suggests that, instead of pondering the notion of design, scientists and theologians might more fruitfully look for new ground for dialogue since feminist scholars are asking very different questions, not just answering questions differently. 相似文献

Although integrity tests are widely applied in screening job applicants, there is a need for research for examining the construct validity of these tests. In the present study, a theoretical model examining the causes of destructive behavior in organizational settings was used to develop background data measures of individual and situational variables that might be related to integrity test scores. Subsequently, 692 undergraduates were asked to complete these background data scales along with (a) two overt integrity tests – the Reid Report and the Personnel Selection Inventory, and (b) two personality‐based measures – the delinquency and socialization scales of the California Psychological Inventory. When scores of these measures were correlated with and regressed on the background data scales, it was found that relevant individual variables, such as narcissism and power motives, and relevant situational variables, such as alienation and exposure to negative peer groups, were related to scores on both types of integrity tests. However, a stronger pattern of validity evidence was obtained for the personality‐based measures and, in all cases, situational variables were found to be better predictors than individual variables. The implications of these findings for the validity of inferences drawn from overt and personality‐based integrity tests are discussed. 相似文献

Women and Salary Negotiation: The Costs of Self-Advocacy 总被引:1,自引:0,他引:1
Mary E. Wade 《Psychology of women quarterly》2001,25(1):65-76
Introducing the concepts of self- and other-advocacy should prove useful as a means of understanding the different contexts in which women and men can effectively and comfortably exert power and influence when making requests. In this conceptual paper, social psychological research is reviewed demonstrating that women can advocate effectively on behalf of others without incurring costs, but gender-linked stereotypes, roles, and norms constrain them from advocating as freely and effectively for themselves. It is argued that women do not frequently make requests for themselves, because they have learned that they may ultimately lose more than they gain. This gendered difference has implications for ongoing pay and promotion inequities. 相似文献

For the families in Palm Beach County who entered the child abuse and neglect system as a result of having a child placed into emergency shelter, their experience was that the system was frequently intimidating, confusing, and fragmented. The reaction of the children and their families to this system was often defensiveness and resistance. To increase the system's effectiveness, it was redesigned and privatized. The redesigned system included centralized shelter placement, a comprehensive assessment, independent service coordination, and treatment service provision within a managed care model. By emphasizing family involvement and quality service provision, the goal was to increase voluntary participation and improve family outcomes. Based on initial data, it appears that the redesigned system has been successfully implemented and has made notable progress toward meeting its system flow timeframes. The initial data also indicate that high percentages of families are participating in and are satisfied with the system, that children are spending less time in shelter placements, and that only one family has reentered the system. 相似文献

Generating solutions to anagrams leads to a memory advantage for those solutions, with generated words remembered better than words simply read. However, an additional advantage is not typically found for solutions to difficult anagrams relative to solutions to easy ones, presenting a challenge for the cognitive effort explanation of the generation effect. In the present series of experiments, the effect of manipulating anagram difficulty is explored further by introducing two new source-monitoring judgments. These studies demonstrate that when attention is directed at test to the operations activated during encoding (by way of source-monitoring judgments focused on solving vs. constructing anagrams), a source advantage is observed for difficult anagrams. However, when attention is directed to the anagrams themselves, asking participants to remember the kinds of anagrams generated or solved (based on kind of rule rather than subjective impressions of difficulty), a similar source advantage is not observed. The present studies bring a new perspective to the investigation of difficulty manipulations on memory for problem solving by illustrating the impact of a shift in focus from the effort mediating cognitive operations to specifics about the cognitive operations themselves. 相似文献
