中小学生认知能力发展水平测验的研究   总被引:4,自引:0,他引:4  
以皮亚杰的认知发展理论为基础,采用皮亚杰及其学生研究认知发展时的任务为测验题目,编制成测量中小学生认知能力发展水平的测验.通过对2240名中小学生施测,结果表明本测验不仅具有很好的信度和效度,而且也具有适中的难度.然后以一所中学特长班学生为被试,通过对他们进行测量,并将测验结果与同年级普通班学生的认知成绩进行比较,结果存在很明显的差异.最后对中小学生认知能力发展水平测量问题进行了探讨.  相似文献

Borderline patients present particular treatment problems and require close, devoted understanding of their often chaotic and shifting intrapsychic conflicts. Many of these patients act out, making it difficult to maintain an analytic process. In fact, many terminate early on. When they do stay for longer periods, they exhibit particular constellations of defense, anxiety, and conflict. One extensive case report is used to examine the overlapping cycles of treatment with this population. Frequently, self-destructive acting-out is present in the transference and extratransference. This acting-out is often followed by the self-destructive, antichange attitude of the death instinct. These ways of relating to the self and the object are mobilized within the vehicle of projective identification and are best understood as primitive defenses against core fantasies of loss and persecution. These issues of loss and fear are the final and vital phase of treatment with borderline patients, who are often able to make major fundamental changes in their internal sphere, but only if patient and analyst can tolerate and understand these three levels of intrapsychic experience.  相似文献

Cognitive models of social anxiety implicate various factors in the initiation and maintenance of socially anxious states, including anticipatory processing, self-focused attention and post-event processing. The present study focused on post-event processing, which is a post-mortem analysis following a social event that is described as ruminative in nature and serves to maintain social anxiety. Participants (N=112; 64 women, 48 men) were presented with vignettes that involved making mistakes in public and were instructed to record their thoughts to allow for the examination of the content of post-event processing. Ruminative coping and distraction were assessed via self-report. Results indicated that participants high in social anxiety (n=55) were more likely to ruminate and less likely to distract when faced with socially anxious stressors compared to those low in social anxiety (n=57). Further, as hypothesized, participants high in social anxiety recorded more negative thoughts and more upward counterfactual thoughts ('if only' type thoughts on how things could have been better; associated with negative affect) compared to those low in social anxiety. These results are discussed in terms of cognitive models of social anxiety.  相似文献

Hypochondriasis is a debilitating condition in which patients are persistently preoccupied with the possibility of being seriously ill. Its is a costly problem for the health care system whose treatment has not received systematic attention until recently. Although based on few controlled studies, results indicated that various brief cognitive-behavioral techniques produce significant changes in illness fears and attitudes. A list of therapeutic questions that require further study is presented and some indications for both therapists and patients are given.  相似文献

People often claim that they perform better in memory performance tasks when they are more motivated. However, past research has shown minimal effects of motivation on memory performance when factors contributing to item-specific biases during encoding and retrieval are taken into account. The purpose of the present study was to examine the generality of this apparent dissociation by using more sensitive measures of experienced motivation and memory performance. Extrinsic motivation was manipulated through competition instructions, and subjective ratings of intrinsic and extrinsic motivation were obtained before and after study instructions. Participants studied a series of words, and memory performance was assessed by content recall (Experiment 1) and source recall (Experiment 2). Both experiments showed dissociation between subjective ratings of extrinsic motivation and actual memory performance, so that competition increased self-rated extrinsic motivation but had no effects on memory performance, including source recall. Inconsistent with most people's expectations, the findings suggest that extrinsic motivation has minimal effects on memory performance.  相似文献

Two new tests for a model for the response times on pure speed tests by Rasch (1960) are proposed. The model is based on the assumption that the test response times are approximately gamma distributed, with known index parameters and unknown rate parameters. The rate parameters are decomposed in a subject ability parameter and a test difficulty parameter. By treating the ability as a gamma distributed random variable, maximum marginal likelihood (MML) estimators for the test difficulty parameters and the parameters of the ability distribution are easily derived. Also the model tests proposed here pertain to the framework of MML. Two tests or modification indices are proposed. The first one is focused on the assumption of local stochastic independence, the second one on the assumption of the test characteristic functions. The tests are based on Lagrange multiplier statistics, and can therefore be computed using the parameter estimates under the null model. Therefore, model violations for all items and pairs of items can be assessed as a by-product of one single estimation run. Power studies and applications to real data are included as numerical examples.  相似文献

Emotion Socialization in Families of Children With an Anxiety Disorder   总被引:1,自引:0,他引:1  
Compared emotion socialization in 26 children with anxiety disorders ages 8–12 years and their mothers to 26 nonclinical counterparts without psychopathology. Children and their mothers participated in an emotion interaction task in which they discussed occasions when the child felt worry, sadness, and anger. Responses were coded for length of discussion, proportion of words spoken by child vs. mother, frequency of positive and negative emotion words, explanatory discussion of emotion, and maternal facilitation of emotion discussion. Children and their mothers also completed the Expressiveness and Control scales of the Family Environment Scale. Results indicated that mothers of children with an anxiety disorder spoke less frequently than their child, used significantly fewer positive emotion words, and discouraged their childrens emotion discussions more than did mothers of nonclinical children. Nonclinical children and their mothers indicated significantly more emotional expressiveness in their families than did children with an anxiety disorder and their mothers. These results highlight the potential role of truncated family emotional expressivity in the emotional development and functioning of children with an anxiety disorder.  相似文献

Most of the existing research on outcomes of job insecurity has identified individual-level burdens such as reduced attitudinal attachments toward work and well being. Far fewer studies have examined work-related outcomes that are of substantial concern to organizational success. In this paper, we investigated four new work-related outcomes of job insecurity that are part of the literature on key account management (KAM): customer performance, effectiveness with customers, adaptiveness to changing competitive conditions, and esprit de corps. A total of 353 U.S. based employees participated. The findings of this research suggest that job insecure workers perceive their organizations to be ineffective in delivering on all four KAM outcomes.  相似文献

The authors investigated the psychometric properties of the Beck Anxiety Inventory (BAI) in a sample of 75 older generalized anxiety disorder (GAD) patients and a comparison group of 32 older adults without significant psychopathology. Internal consistency was above .80, and the BAI showed evidence of convergent validity in both groups. Evidence for discriminant validity with respect to measures of depression was weaker. Two items, fearing the worst and nervousness, correctly distinguished 86.5% of patients with GAD and 93.8% of the normal controls. Medical comorbidity was associated with somatic but not cognitive anxiety symptoms in the normal older sample. Overall, results indicate the limitations of the BAI in assessing anxiety symptoms in older adults and suggest the need for use of an instrument focusing on cognitive aspects of anxiety.  相似文献
