Durable and generalized effects of spatial experience on mental rotation: gender differences in growth patterns 总被引:1,自引:0,他引:1
Melissa S. Terlecki Nora S. Newcombe Michelle Little 《Applied cognitive psychology》2008,22(7):996-1013
This study addressed questions about improvement in mental rotation skills: (1) whether growth trajectories differ for men and women with higher or lower spatial experience, (2) whether videogame training has effects on performance and leads to transfer, (3) whether effects of repeated testing or training effects are durable and (4) whether transfer is durable. Undergraduates participated in repeated testing on the MRT or played the videogame Tetris. Analyses showed large improvements in mental rotation with both repeated testing and training; these gains were maintained several months later. MRT scores of men and women did not converge, but men showed faster initial growth and women showed more improvement later. Videogame training showed greater initial growth than repeated testing alone, but final performance did not differ. Effects of videogame training transferred to other spatial tasks exceeding the effects of repeated testing, and this transfer advantage was still evident after several months.

Happiness is a personal(ity) thing: the genetics of personality and well-being in a representative sample. 总被引:3,自引:0,他引:3
Subjective well-being is known to be related to personality traits. However, to date, nobody has examined whether personality and subjective well-being share a common genetic structure. We used a representative sample of 973 twin pairs to test the hypothesis that heritable differences in subjective well-being are entirely accounted for by the genetic architecture of the Five-Factor Model's personality domains. Results supported this model. Subjective well-being was accounted for by unique genetic influences from Neuroticism, Extraversion, and Conscientiousness, and by a common genetic factor that influenced all five personality domains in the directions of low Neuroticism and high Extraversion, Openness, Agreeableness, and Conscientiousness. These findings indicate that subjective well-being is linked to personality by common genes and that personality may form an "affective reserve" relevant to set-point maintenance and changes in set point over time. 相似文献

Previous research has demonstrated discrimination of scrambled from typical human body shapes at 15–18 months of age [Slaughter, V., & Heron, M. (2004). Origins and early development of human body knowledge. Monographs of the Society for Research in Child Development, 69]. In the current study 18-, 24- and 30-month-old infants were presented with four typical and four scrambled dolls in a sequential touching procedure, to assess the development of explicit categorization of human body shapes. Infants were also presented with typical and scrambled cars, allowing comparison of infants’ categorization of scrambled and typical exemplars in a different domain. Spontaneous comments regarding category membership were recorded. Girls categorized dolls and cars as typical or scrambled at 30 months, whereas boys only categorized the cars. Earliest categorization was for typical and scrambled cars, at 24 months, but only for boys. Language-based knowledge, coded from infants’ comments, followed the same pattern. This suggests that human body knowledge does not have privileged status in infancy. Gender differences in performance are discussed. 相似文献

The role of arms in compliant-surface jumping for maximizing backward somersault rotations is studied using multi-segment models and is applied to springboard diving. The surface (springboard) is modeled by a rigid bar with a rotational spring with a hinged end and point mass at the tip. Planar four- and five-segment human models are used (with the fifth segment representing the arms) and are driven by torque actuators at the ankle, knee, hip, and shoulder. Each joint torque is the product of maximum isometric torque and three variable functions depending on instantaneous joint angle, angular velocity, and activation level, respectively. Movement simulation starts from a balanced initial posture and ends at jump takeoff. The objective is to find joint torque activation patterns during board contact so that the number of backward rotations in flight is maximized. Kinematic differences in jumps with and without arms are mainly in smaller takeoff vertical velocity and more flexed knee and hip in the former. In both jumps, joint torque/activations are similar in their minor flexion-full extension patterns. Maximum hip torque is larger with arms but maximum knee torque is larger without arms. Except at the knee, more joint work can be done with arm swing. Total angular momentum is increased considerably by arm motion because of its remote contribution. Consequently segment remote contributions to total angular momentum are much larger in jumping with arms. Shoulder strength helps generate angular momentum only to a certain limit. If more work is used to generate horizontal velocity away from the board, the amount of total angular momentum is reduced. 相似文献

A dual-process approach to health risk decision making: The prototype willingness model 总被引:1,自引:0,他引:1
Meg Gerrard Frederick X. Gibbons Amy E. Houlihan Michelle L. Stock Elizabeth A. Pomery 《Developmental Review》2008,28(1):29
Although dual-process models in cognitive, personality, and social psychology have stimulated a large body of research about analytic and heuristic modes of decision making, these models have seldom been applied to the study of adolescent risk behaviors. In addition, the developmental course of these two kinds of information processing, and their relation to the development of self-regulation are not well understood at this time. The current paper reviews what leading dual-process models have to say about the development of analytic and heuristic decision making, and their implications for adolescent risk behavior. In addition, it reviews research on the prototype willingness model of adolescent decision making—a dual-process model designed specifically to address non-intentional, but volitional adolescent risk behavior. It also discusses the implications of dual-process models for intervention research. 相似文献

This article introduces an intersectional approach to political consciousness and presents data to demonstrate its importance for predicting solidarity in diverse social change organizations. Women activists ( N = 174) completed measures of political consciousness, diversity, and solidarity. As expected, women differed in the degree to which their political consciousness reflected intersectionality (sensitivity to intragroup differences arising from intersections of social identities, such as ethnicity with gender) and singularity (focus on intragroup similarities arising from a shared social identity, such as gender). Although high group diversity related to lower solidarity, the content of political consciousness moderated the negative association of diversity to solidarity. High diversity had a negative association with solidarity only when political consciousness reflected a high degree of singularity and a low degree of intersectionality. These findings challenge the common assumption that diversity undermines a group's ability to work together and suggest that, when appreciation of difference is an important aspect of an individual's identity, solidarity with a social change organization may be greater when group diversity is high rather than low. 相似文献

This study examines the potential impact of family conflict and cohesion, and peer support/bullying on children with autism
spectrum disorder (ASD). While such impacts have been established for a range of non-ASD childhood disorders, these findings
may not generalize to children with ASD because of unique problems in perspective-taking, understanding others’ emotion, cognitive
rigidity, and social reasoning. A structural model-building approach was used to test the extent to which family and peer
variables directly or indirectly affected ASD via child anxiety/depression. The sample (N = 322) consisted of parents of children with ASD referred to two specialist clinics. The sample contained parents of children
with Autistic Disorder (n = 76), Asperger Disorder (n = 188), Pervasive Disorder Not Otherwise Specified (n = 21), and children with a non-ASD or no diagnosis (n = 37). Parents completed questionnaires on-line via a secure website. The key findings were that anxiety/depression and ASD
symptomatology were significantly related, and family conflict was more predictive of ASD symptomatology than positive family/peer
influences. The results point to the utility of expanding interventions to include conflict management for couples, even when
conflict and family distress is low. Further research is needed on the potentially different meanings of family cohesion and
conflict for children with ASD relative to children without ASD. 相似文献

A sample of devout Christian adults, ranging widely in political orientation, described what their lives (and the world) might be like had they never embraced faith. Politically conservative Christians (also scoring high on right-wing authoritarianism) tended to imagine a life deficient in impulse control, wherein unrestrained sexual and aggressive urges, addictive behaviors, and human selfishness undermined the social good. By contrast, politically liberal Christians (also scoring low on right-wing authoritarianism) imagined an empty and barren world, devoid of the emotional intensity that makes life worth living. Gender differences were also observed, but they did not interfere with the relation between political orientation and the narrative themes. In accord with theoretical writings regarding normative and humanistic ideologies, the findings suggest that, at least among American Christians, political conservatism may entail a fear of, or strong sensitivity to, the prospects of conflict and chaos, whereas political liberalism may entail an equally strong fear of, or sensitivity to, emptiness. 相似文献

Juvenile sex offenders (JSOs) often appear unmotivated to change, which thus necessitates a therapeutic approach that matches “resistant” client characteristics. In this article, the authors review common traits of JSOs, introduce motivational counseling as an effective treatment modality, and offer a case illustration. 相似文献
