This study was designed to determine whether memory for stimulus values is a Bayesian weighting of the magnitude of a stimulus and the central tendency of an exemplar's category (Huttenlocher, Hedges, & Vevea, 2000). In five experiments, participants reproduced the remembered size of a geometric figure drawn from one of two categories whose means for size differed. Reproductions were biased toward the mean of the combined distribution rather than the mean of either category. Reproductions were also influenced by the size of the stimulus on the preceding trial. Neither of these results is entirely consistent with the view that recollections are partially constructed from a consideration of the long-run probabilities established by category membership. 相似文献

Inhibition of abandoned tasks in task switching can be inferred when a worse performance is found withn− 2 task repetitions (ABA sequences) than with nonrepetitions (CBA sequences). Recent evidence has shown that this inhibition
effect decreases with long intertrial intervals (i.e., response-cue intervals, RCIs). Two alternatives have been proposed
to account for this decrease. One alternative attributes the observed decrease to the decay of inhibition itself. The other
alternative proposes that decay of the activation of competing tasks reduces the interference and leads to less inhibition.
To decide between these alternatives, we manipulated RCI trialwise. The results favor the decay-of-activation account as an
explanation for the decreased inhibition effect. This links the amount of inhibition to the activation level of the competing
tasks, whereas evidence for the decay of inhibition remains weak. 相似文献

Case management has emerged as an integral component of current efforts to reform the delivery of mental health services to children and youth with Severe Emotional Disturbance (SED). We examined parental satisfaction with one program's case management system for SED children. In order to validly address parental satisfaction, the program first turned to a group of its parents to develop a satisfaction measure, the Family Satisfaction Survey (FSS). Of the 51 parents who returned an FSS, 74% of the parents were generally satisfied while 26% indicated that they were dissatisfied with their families' case management services. Multivariate regression analyses were employed to examine the role played by client, service, and outcome variables in predicting parental satisfaction. After controlling for child diagnoses, severity of impairment, and levels of psychosocial stress, parent satisfaction with case management services was best predicted by the frequency of monthly contact and fewer days is a psychiatric hospital proportional to length of service. Our results suggest that parent satisfaction is based not only on what case managers do but on how this service impacts SED children's ability to remain at home and in their communities. 相似文献

Teaching, like other professions, has a developing knowledge base that serves to guide practitioners (Shulman, 1986). Knowledge generated by research is an important component of this knowledge. What are some avenues for dissemination of such research? What are the main impediments to the success of this endeavor? What is a possible link between dissemination efforts and the use of research knowledge by teachers? These questions will be dealt with in this paper. 相似文献

The purpose of this paper is to show how failures of adjustment of Soviet refugees to America are to a great degree determined by their difficulties in mourning. The author argues that due to such difficulties, Soviet refugees may get fixated sometimes for long periods of time at different stages of the mourning process. Such fixations may be the causes for peculiar types of behavior, frequently exhibited by these refugees in America and attributed by various authors to their psychocultural characteristics. Melanie Klein's analysis of mourning and its relationship to manic depressive states is applied to understand the mourning process in this population. The author shows that difficulties in the mourning process experienced by Soviet refugees may be connected with the culturally acquired inhibitions of mourning. Such inhibitions are analyzed from a family, historical and cultural perspective. 相似文献

In five experiments, in which subjects were to identify a target word as it was gradually clarified, we manipulated the target's frequency of occurrence in the language and its neighborhood size—the number of words that can be constructed from a target word by changing one letter, while preserving letter position. In Experiments 1–4, visual identification performance to screen-fragmented words was measured. In Experiments 1 and 2, we used the ascending method of limits, whereas Experiments 3 and 4 presented a fixed-level fragment. In Experiment 1, there was no relation between overall accuracy and neighborhood size for-words-between three and six letters in length. However, more errors of commission (guesses) were made for high-neighborhood words and more errors of omission (blanks) were made for low-neighborhood words. Letter errors within guesses occurred at serial positions having many neighbors, and these positions were also likely to contain consonants rather than vowels. In Experiment 2, a smallfacilitatory effect of neighborhood size on bothhigh- and low-frequency words was found. In contrast, in Experiments 3 and 4, using the same set of words,inhibitory effects of neighborhood size, but only for low-frequency words, were found. Experiment 5, using a speeded identification task, showed results parallel to those of Experiments 3 and 4. We suggest that whether neighborhood effects are facilitatory or inhibitory depends on whether feedback allows subjects to disconfirm initial hypotheses that the target is a high-frequency neighbor. 相似文献

We examined the relationship between family empowerment, parent satisfaction, and mental health outcome across time. Based on the Vanderbilt Family Empowerment Project Model, increased empowerment should lead to positive changes in client outcomes. Data consisted of the Family Empowerment Scale (FES), which was used to assess the caregiver's perception of empowerment, Child and Adolescent Functional Assessment Scale (CAFAS), which measures the degree of disruption in the youth's current functioning, Client Satisfaction Questionnaire (CSQ), and demographic information gathered from families receiving services from a county mental health service system at intake and discharge. The results showed that the CAFAS and CSQ were related to empowerment at intake and discharge. Results also indicated significant increases in the knowledge subscale of the FES and the CAFAS and moderate increases in the advocacy subscale of the FES and the CSQ. We discuss the implications of these findings for systems of care, such as stronger parent-professional relationships. 相似文献

Behavioral researchers have developed a sophisticated methodology to evaluate behavioral change which is dependent upon accurate measurement of behavior. Direct observation of behavior has traditionally been the mainstay of behavioral measurement. Consequently, researchers must attend to the psychometric properties, such as interobserver agreement, of observational measures to ensure reliable and valid measurement. Of the many indices of interobserver agreement, percentage of agreement is the most popular. Its use persists despite repeated admonitions and empirical evidence indicating that it is not the most psychometrically sound statistic to determine interobserver agreement due to its inability to take chance into account. Cohen's (1960) kappa has long been proposed as the more psychometrically sound statistic for assessing interobserver agreement. Kappa is described and computational methods are presented. 相似文献

Basic theoretical paradigms and constructs are identified within the extant literature that may usefully contribute to comprehending the effect of war upon young children as well as the nature of personal, situational, and familial moderating factors. These concerns are illustrated with empirical data regarding infants and toddlers and their response to the recent Gulf War. Potential applications of these heuristic models are explicated for the study of war as well as for the design of preventive and remedial programming. 相似文献

Speakers of English frequently associate location in space with valence, as in moving up and down the “social ladder.” If such an association also holds for the sagittal axis, an object “in front of” another object would be evaluated more positively than the one “behind.” Yet how people conceptualize relative locations depends on which frame of reference (FoR) they adopt—and hence on cross-linguistically diverging preferences. What is conceptualized as “in front” in one variant of the relative FoR (e.g., translation) is “behind” under another variant (reflection), and vice versa. Do such diverging conceptualizations of an object's location also lead to diverging evaluations? In two studies employing an implicit association test, we demonstrate, first, that speakers of German, Chinese, and Japanese indeed evaluate the object “in front of” another object more positively than the one “behind.” Second, and crucially, the reversal of which object is conceptualized as “in front” involves a corresponding reversal of valence, suggesting an impact of linguistically imparted FoR preferences on evaluative processes. 相似文献
