In 3 experiments, participants, on signal, moved a cursor from a central position to 1 of 8 numerically labeled locations on the circumference of a clock face. Movements were controlled by a mouse in 1 of 4 conditions: vertical reversal, horizontal reversal, combined reversals, or normal (i.e., no reversals). Participants were trained in 1, 2, or 3 of these conditions and were tested 1 week later with either the same or a different condition. There were improvements across training and perfect retention across the delay. There was little or no transfer, however, even when training involved combined reversals or multiple conditions. These results illustrate severe specificity of training and are interpreted in terms of acquired inhibition of normal responses. 相似文献

This study measures the effect of Alzheimer's disease (AD) and normal aging on the inhibition of prepotent responses. AD patients, normal aged controls, and young subjects were tested with the Hayling task, which measures the ability to inhibit a semantically constrained response, and with the Stroop procedure. AD patients showed a severe deficit in both error rates and response time on the Hayling task. Inhibition was also impaired on the Stroop procedure, both when using raw performance and when using an inhibition score that controlled for reading and naming speed. Normal aged participants showed modest impairment relative to young controls on both tests. Examination of individual performance in AD patients indicated that the impairment was found in most patients on the Hayling test but in only a subgroup of patients on the Stroop test. 相似文献

Genetic and environmental influences on mothering of adolescents: a comparison of two samples 总被引:6,自引:0,他引:6
Neiderhiser JM Reiss D Pedersen NL Lichtenstein P Spotts EL Hansson K Cederblad M Ellhammer O 《Developmental psychology》2004,40(3):335-351
This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of positivity, negativity, control, and monitoring were used. The use of matched child-based and parent-based samples enabled passive and nonpassive genotype-environment (GE) correlations to be approximated, providing information about process. Passive GE correlations were suggested for mother's positivity and monitoring. For mother's negativity and control, primarily nonpassive GE correlations were suggested. In several cases, both types of GE correlation were indicated. Finally, observer ratings of negativity and monitoring were influenced only by environmental factors. 相似文献

Impact of executive dysfunctions on episodic memory abilities in patients with ruptured aneurysm of the anterior communicating artery 总被引:3,自引:0,他引:3
Executive and memory dysfunctions are among the most frequently reported deficits following a ruptured aneurysm of the anterior communicating artery (ACoA). In order to study the impact of the dysexecutive syndrome on episodic and semantic memory, the data obtained from 59 ACoA patients were examined retrospectively. All patients were assessed on a variety of episodic memory tests (Rey Auditory-Verbal Learning Test, Rey Complex Figure Test, Weschler Memory Scale), semantic memory (verbal fluency), and standardized tests of executive functions (Trail Making Test, Maze tests, Wisconsin Card Sorting Test). There was a strong positive correlation between executive dysfunction and retrieval difficulties in episodic and semantic memory tasks. Comparisons of subgroups of patients with high and low frontal lobe functioning on delayed recall and recognition revealed a significant group X condition interaction in addition to significant group and condition main effects. ACoAs patients with low frontal lobe functioning were particularly deficient in free recall (immediate and delayed) while recognition was equally well preserved in the two subgroups. Neither subgroup presented with an abnormal forgetting over time suggesting a retrieval deficit rather than a true retention impairment. 相似文献

In this study, we investigated the psychometric properties of the Sensation Seeking Scale-V (SSS-V; Zuckerman, Eysenck, & Eysenck, 1978). Participants were 498 undergraduate students at a public university. A confirmatory factor analysis supported the SSS-V four-factor structure. In addition, the internal consistency was high and the convergent validity of the SSS-V was supported. These findings replicate research supporting the construct validity and reliability of the SSS-V in a nonclinical college sample. 相似文献

In two studies, we investigated whether using three-dimensional (3D) manipulatives during assessment aided performance on a variety of preschool mathematics tasks compared to pictorial representations. On measures of children's understanding of counting and cardinality (n = 103), there was no difference in performance between manipulatives and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. On a measure of children's shape identification (n = 93), there was no difference in performance between objects and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. These results suggest flexibility in the materials that can be used during assessment. Pictures, or 2D renderings of 3D objects, which can be easily printed and reproduced, may be sufficient for assessing counting and shape knowledge without the need for more cumbersome concrete manipulatives. 相似文献

The message that women should be thin comes from many sources; some of which may be using the terminology loosely. To test this, the Figure Rating Scale was mailed to 547 personal ad writers to examine the actual preferences of those seeking a thin partner, those seeking a physically fit partner, and those giving no weight preference. Respondents indicated ideal and acceptable body sizes for partners. The ethnicity of respondents was 85.1% White, 7.5% Hispanic, 1.4% African American, 0.7% American Indian, and 4.1% other. The mean education level was 16.6 years and the average annual income was about $40,000. Although males in the three ad categories had statistically significant differences in their choice of an ideal figure, the actual figure size differences appeared negligible, and men did not differ in the number of figures they found acceptable. Females chose the same figure as ideal despite different weight requests. The implications of males accepting a wide range of body sizes for a partner despite specifically requesting a thin one are discussed. 相似文献

The Effects of Tai Chi Chuan Relaxation and Exercise on Stress Responses and Well-Being: An Overview of Research 总被引:3,自引:0,他引:3
The rationale of this article is to review, analyze, and discuss studies concerning the role of Tai Chi in stress management and well-being, linking those studies to research on exercise, yoga, and relaxation with regard to physiological and psychological wellness. All studies reported in PsychLit and Medline between 1996 and 1999 directly related to the subject, plus other studies relevant for the analysis, are addressed in this review. Studies reviewed in this article characterize Tai Chi as a form of moderate exercise. Although Tai Chi may not be suitable for achieving aerobic fitness, it may enhance flexibility and overall psychological well-being. Cognitively, there are indications that Tai Chi exercise may lead to improvements in mood. However, it is not clear whether the positive effects of Tai Chi are due solely to its relaxation and meditation component, or whether they are the consequence of various peripheral factors, since it is known that stress reduction often occurs when we indulge in activities we find pleasurable and satisfying. An important finding is that all studies on the benefits of Tai Chi for senior adults have revealed positive results. 相似文献

This article describes and evaluates the implementation of an innovative approach to systems change, the incubation approach,
which was developed on a systems change project designed to increase the capacity of multiple systems (e.g., law enforcement,
child protection, domestic violence, mental health, early education) to respond to children’s exposure to violence. The incubation
approach encourages change agents to collaborate with project staff to gently nurture, or “incubate,” feasible and warranted
change in target systems. Project staff gain concrete commitment from motivated and accessible change agents and collaborate
with those agents to implement change actions. This approach works well with committed, executive-level change agents in target
systems, with stable systems that have low turnover and well-integrated subsystems, and when seed funds are provided to key
organizations. 相似文献
