Age differences in adults' memory for performed actions (e.g., wave hand) are sometimes smaller than age differences in memory for nonperformed phrases. In this study, we examined the conditions under which performance reduces age differences in recall. Younger and older adults performed or read verb-noun phrases that were either related (e.g., actions performed in a kitchen) or unrelated. Performance did not reduce age differences in recall of the exact verbs and nouns used to describe an action, but performance did reduce age differences in memory for the gist of related actions. Older adults especially had difficulty recalling the exact verb used to describe the action. These results suggest that older adults may have better memory for actions than is revealed by tests of verbatim recall. They may remember performing the action but not remember the exact words used to describe the action.  相似文献

The Social Phobia and Anxiety Inventory (SPAI) is a new instrument composed of social phobia and agoraphobia subscales. The latter scale is used to detect social anxiety that may result from agoraphobia. The SPAI's construct validity was assessed through several procedures. First, confirmatory factor analyses were conducted to validate the existence of the two subscales. Second, exploratory factor analyses examined the underlying structure of the social phobia subscale. Third, a Q factor procedure determined if different anxiety diagnostic groups could be differentiated by their SPAI response pattern. The results confirmed the utility of the two SPAI subscales and identified a number of dimensions contained within the social phobia subscale which differed depending upon the specific subject sample. In addition, the complaints of social phobies appeared more homogeneous than those of an agoraphobic comparison group. The results are discussed in terms of construct validity and the sensitivity of the SPAI to various dimensions of social phobia fears.This study was supported in part by NIMH Grants 41852, 30915, 18269, and 16884.  相似文献

Voice control, a punishment technique based on loud commands, has been used widely in pediatric dentistry. This study examined whether (a) loudness is a necessary component of the technique, (b) voice control actually reduces children's disruptive behavior, and (c) after treatment, children's negative affect increases. Subjects were forty 3 1/2- to 7-year-olds who posed potential behavior problems and who were scheduled for cavity restoration. Children were assigned randomly to either loud- or normal-voice groups. Children who were assigned to either group but who were not disruptive formed a nonexperimental control group. Prior to and after treatment, children reported their feelings using the Self-Assessment Mannequin. Disruptive behavior was scored using the Behavior Profile Rating Scale. Results indicated that, following loud, but not normal voice commands, children reduced their disruptive behavior (p less than .004) and self-reported lower arousal (p less than .09) and greater pleasure (p less than .10). Theoretical and practical implications of these findings are discussed.  相似文献

In three experiments we studied the relationship between contextual conditioning and the reinstatement of extinguished lever pressing that occurs when noncontingent food is introduced following extinction. In all three experiments the non-contingent food was presented off-baseline (with the response levers not present). On subsequent tests, with the response levers present, animals that had been exposed to food showed more reinstatement of lever pressing than control animals. This finding rules out alternative mechanisms for the reinstated responding that rely on the interaction of non-contingent food and responding, such as superstitious reinforcement or the discriminative after-effects of food. In addition, in each experiment we demonstrated that manipulations known to affect contextual conditioning (signalling the food in Experiment 1, context extinction in Experiment 2, and switching contexts in Experiment 3) reduced the reinstatement. These results are consistent with the claim that contextual conditioning is important in controlling instrumental conditioning and closely parallel findings concerning the reinstatement of Pavlovian responsing following extinction.  相似文献

This article demonstrates the use of mixed-effects logistic regression (MLR) for conducting sequential analyses of binary observational data. MLR is a special case of the mixed-effects logit modeling framework, which may be applied to multicategorical observational data. The MLR approach is motivated in part by G. A. Dagne, G. W. Howe, C. H. Brown, & B. O. Muthén (2002) advances in general linear mixed models for sequential analyses of observational data in the form of contingency table frequency counts. The advantage of the MLR approach is that it circumvents obstacles in the estimation of random sampling error encountered using Dagne and colleagues' approach. This article demonstrates the MLR model in an analysis of observed sequences of communication in a sample of young adult same-sex peer dyads. The results obtained using MLR are compared with those of a parallel analysis using Dagne and colleagues' linear mixed model for binary observational data in the form of log odds ratios. Similarities and differences between the results of the 2 approaches are discussed. Implications for the use of linear mixed models versus mixed-effects logit models for sequential analyses are considered.  相似文献

One of the most exciting developments in intergroup contact theory is the idea that a certain type of contact, cross-group friendship, might be particularly effective at reducing prejudice. In this chapter we review research on two types of cross-group friendship. Direct cross-group friendship refers to friendships that develop between members of different groups. Extended cross-group friendship, on the other hand, refers to vicarious experience of cross-group friendship, the mere knowledge that other ingroup members have cross-group friends. We consider the relationship between both types of cross-group friendship and prejudice and the processes that mediate and moderate these relationships. The research highlights the respective strengths and weaknesses of direct and extended cross-group friendship and illustrates how they might be practically combined in efforts to improve intergroup relations.  相似文献

Posttraumatic stress disorder (PTSD) and substance use disorder (SUD) commonly co-occur. Emerging research suggests that both distress tolerance and impulsivity may underlie this comorbidity. However, to our knowledge no studies have examined whether these 2 constructs predict outcome in PTSD-SUD treatment. The current study investigated whether pretreatment distress tolerance and impulsivity predicted posttreatment PTSD and cravings severity in a sample of 70 Veterans receiving concurrent treatment for PTSD and SUD in a residential day treatment program. Veterans completed measures of symptom severity before and after treatment. Results demonstrated that pretreatment distress tolerance predicted posttreatment PTSD severity while controlling for pretreatment PTSD. By contrast, pretreatment impulsivity was not predictive of posttreatment PTSD while controlling for pretreatment values. Neither distress tolerance nor impulsivity predicted posttreatment cravings severity. The findings support the notion that distress tolerance may help to explain the co-occurrence of PTSD and SUD and suggest that targeting this construct in PTSD-SUD treatment may be important for successful outcomes.  相似文献

Most research on couple communication patterns comes from North America and Europe and suggests cross-cultural universality in effects, but emerging studies suggest that couple communication takes different forms depending on the cultural context in which it occurs. The current study addressed this discrepancy by comparing the observed social support behaviors of 50 newlywed American couples and 41 newlywed Mainland Chinese couples, first on mean levels of positivity and negativity and second on behavior-satisfaction associations. Consistent with predictions derived from observational work by Tsai and Levenson (1997), Chinese couples were observed displaying significantly more negative behavior than American couples, even after controlling for relationship satisfaction; the 2 groups did not differ in observed positive behaviors. Tests of the moderating role of culture on behavior-satisfaction associations showed that positivity was significantly related to relationship satisfaction only for American husbands, whereas negativity was significantly associated with relationship satisfaction only for Chinese husbands. We speculate that cultural contexts may influence the display and evaluation of behavior in intimate relationships, suggesting the need for caution when generalizing models and associated interventions to non-Western couples.  相似文献
