Gender differences in episodic memory

The relationship between gender and memory has been largely neglected by research, despite occasional studies reporting gender differences in episodic memory performance. The present study examined potential gender differences in episodic memory, semantic memory, primary memory, and priming. Five hundred thirty women and 470 men, randomly sampled from the city of Umeå, Sweden, 35–80 years of age, participated in the study. There were no differences between men and women with regard to age or education, or on a measure of global intellectual functioning. As has been demonstrated previously, men outperformed women on a visuospatial task and women outperformed men on tests of verbal fluency. In addition, the results demonstrated that women consistently performed at a higher level than did men on the episodic memory tasks, although there were no differences between men and women on the tasks assessing semantic memory, primary memory, or priming. The women’s higher level of performance on the episodic memory tasks could not be fully explained by their higher verbal ability.     

HUMOR AND INCLINATION TO LAUGH: EMOTIONAL REACTIONS TO STIMULI OF DIFFERENT DIVERGENCE FROM A RANGE OF EXPECTANCY

An experiment was conducted to test the general hypothesis, derived from the incongruity theory of humor, that the experience of humor or of the inclination to laugh is a function of the divergence of a perceived state of affairs from the expected state. The hypothesis was tested with weights as stimuli in two designs. In the first the range of expectancy was defined in terms of the proportion of "heavy" ratings in the subject group at various initial weights. In the second the range of expectancy among subjects was assumed to move with experience with various ranges of weights. The results of both designs supported the hypothesis.     

Ways of acquiring phobias and outcome of behavioral treatments

The way of acquisition of phobias was studied in relation to different behavioral treatments for phobias. Ss (N = 183) were clinical patients belonging to six different phobic groups (agoraphobics, claustrophobics, social phobics, animal phobics, blood phobics and dental phobics), and the treatments were categorized as behaviorally focused (exposure in vivo and social-skills training), physiologically focused (systematic desensitization and applied relaxation) and cognitively focused (self-instruction training and fading). Results showed that both for patients with direct conditioning experiences and indirect acquisition those treated with behavioral and physiological methods improved more than those receiving cognitive methods when looking at the change-score data. Regarding the proportion of clinically improved patients there was no difference between treatments among the Ss with a background of conditioning experiences. In the group with indirect acquisition, on the other hand, the cognitive methods were more effective.     

Fading—A new technique in the treatment of phobias

Phobias have been subject to more research by behavior therapists than any other psychiatric disorder. In 1975 Marks described more than 20 different techniques that have been developed for or used in the treatment of phobias.The technique to be described in this paper—fading—was first used by Barlow and Agras (1973) as an alternative to aversive techniques for homosexuals. Originally the technique was designed to change the stimulus control of sexual responsiveness by introducing or “fading in” heterosexual stimuli during periods of sexual arousal elicted by homosexual stimuli.One purpose of the single-case studies presented here was to explore the possibility of achieving a similar result with phobic clients. In other words, the aim was to create a state of calmness and positive sensations in the client and then to gradually “fade in” phobic stimuli. The hypothesis was that the stimulus control of anxiety exerted by the phobic stimuli would decrease and finally be extinguished due to the antagonistic effects of observing and imagining positive scenes.A second purpose of this application of fading was to develop a technique for reducing phobic anxiety which could give more control to the client than is the case in, for example, systematic desensitization.     

The role of integration in recognition failure and action memory

In three experiments, we studied memory for action events with respect to exceptions from the Tulving-Wiseman function demonstrated in experiments on recognition failure of recallable words. In Experiment 1, we examined exceptions of poor integration in a regular recognition failure condition (i.e., recognition of targets without contextual cues, followed by recall of targets in the presence of contextual cues). In Experiment 2, we examined exceptions of cue overlap in which subjects also had access to the information of contextual cues at recognition test. In Experiment 3, we attempted to equate the levels of recognition across the action and verbal encoding. In addition, the cue overlap and no-cue overlap conditions were studied in a within-subjects design. Results from the three experiments indicated that encoding enactment (episodic integration) and conceptual integration (semantic integration) are related to each other. As a consequence of this relationship, there is a larger independence between recognition and recall of well-integrated items with encoding enactment. On the other hand, for the poorly integrated items without encoding enactment, there is a larger dependence between recognition and recall. Even in the cue overlap condition, where there is a case of large dependence between recognition and recall, the same pattern of data was observed. The results are discussed in terms of an episodic integration view of encoding enactment.     

The effect of retrieval enactment on recall of subject-performed tasks and verbal tasks

The effect of retrieval enactment on memory for nouns (objects) or verbal phrases describing simple actions (e.g., “lift the box”) was addressed in two experiments. In Experiment 1, the type of object involved in the actions was manipulated, with three different types of object being used (body parts, laboratory-related objects, and external objects). In Experiment 2, the integration between the verb-noun pairs was manipulated (well-integrated vs. poorly integrated). Results from both experiments showed that whereas encoding enactment (motor encoding and verbal test) substantially improved the memory performance compared with a verbal condition (verbal encoding and verbal test), retrieval enactment (verbal encoding and motor test) had no major impact on the number of recalled nouns or phrases. Moreover, there was no additional effect of dual enactment (motor encoding and motor test). The overall pattern of the results suggests that there is a fundamental difference between motor processing at encoding and motor processing at retrieval, and the lack of encoding specificity advantage for the motor modality contradicts the view that encoding enactment of verbal commands results in storage of motor representations.     

Exploring Child and Parent Factors in the Diagnostic Agreement on the Anxiety Disorders Interview Schedule

Worryingly low levels of parent–child agreement on child psychiatric diagnosis are reported. This study examined parent–child agreement on diagnostic categories and severity ratings with the Anxiety Disorders Interview Schedule, Child and Parents versions (ADIS-C/P). Children’s age, gender, motivation and self-concept and parent’s general psychopathology and diagnoses were examined. Participants were 110 children (aged 8–14 years) with a principal specific phobia diagnosis, and their parents. Findings revealed excellent parent–child agreement on principal specific phobia diagnosis (97.3%), and fair levels of concordance on most co-occurring secondary diagnoses. As expected, children with high motivation had generally stronger parent–child agreement on diagnoses and severity ratings (for ADHD p?p?p?相似文献   

Adult age differences in the realism of confidence judgments: overconfidence, format dependence, and cognitive predictors

Realistic confidence judgments are essential to everyday functioning, but few studies have addressed the issue of age differences in overconfidence. Therefore, the authors examined this issue with probability judgment and intuitive confidence intervals in a sample of 122 healthy adults (ages: 35-40, 55-60, 70-75 years). In line with predictions based on the na?ve sampling model (P. Juslin, A. Winman, & P. Hansson, 2007), substantial format dependence was observed, with extreme overconfidence when confidence was expressed as an intuitive confidence interval but not when confidence was expressed as a probability judgment. Moreover, an age-related increase in overconfidence was selectively observed when confidence was expressed as intuitive confidence intervals. Structural equation modeling indicated that the age-related increases in overconfidence were mediated by a general cognitive ability factor that may reflect executive processes. Finally, the results indicated that part of the negative influence of increased age on general ability may be compensated for by an age-related increase in domain-relevant knowledge.     

Measurement invariance of personality traits from a five-factor model perspective: multi-group confirmatory factor analyses of the HP5 inventory

Associations between personality and health may be influenced by contextual factors varying across studied cohorts. Moreover, measurement bias related to contextual factors could also influence these associations. Gender and age have been discussed as important contextual factors when studying personality and health outcomes. An examination of measurement invariance across gender and age may therefore be warranted. In the present study, measurement invariance across age and gender was examined for a five-factor model of personality traits in which scales have been included to operationalise lower-order traits related to health-behaviour or health outcomes. Using multi-group confirmatory factor analysis on a population based cohort (n= 5700), all important parameters of the measurement model were found to be invariant. On the basis of this invariant model, hypotheses of mean differences across age and gender in personality traits were tested. These results were discussed in relation to meta-analyses on personality change and gender differences in personality.
