Aging and temporal discrimination of brief auditory intervals 总被引:1,自引:0,他引:1
Summary In a duration-discrimination experiment, young adults (mean age = 25.1), middle-aged adults (mean age = 45.5), and older adults (mean age = 64.6) were presented with two very brief auditorily marked intervals per trial, and their task was to decide which of the two was longer in duration. An adaptive psychophysical procedure was used to determine difference thresholds in relation to a constant standard interval of 50 ms. It was found that duration-discrimination performance was unaffected by age; all three age groups yielded a difference threshold of approximately 17 ms. It was concluded that the ability to discriminate durations of very brief auditory intervals appears to be based on an underlying timing mechanism that does not slow down with advancing adult age. 相似文献

A study of a sample of bereaved and married individuals tested the prediction from stress theory that sex differences in bereavement outcome are due to differences in social support extended to the bereaved. Previous research had established that compared to same‐sex married controls, widowers suffer greater health deterioration following the death of a spouse than widows. Although there is some evidence that widows receive more social support than widowers, it has never been tested empirically whether differential social support is responsible for the sex difference in bereavement outcome. Two sets of tests were conducted to examine these hypotheses: first, sex differences in bereavement outcome and in the social support perceived by the bereaved were assessed by means of sex×marital status ANOVAs on depressive symptomatology, loneliness and social support; second, an ANCOVA was used to assess whether the marital status×sex interaction on distress was substantially reduced or eliminated when social support was used as a covariate. Although there was evidence of the expected sex differences in bereavement outcome and social support, there was no evidence that social support mediates the sex differences in bereavement outcome.

With reference to Mead, Peirce, speech act theory, conversation analysis, and Luhmann's phenomenological grounded version of systems theory, the paper tries to reconstruct actions as products of communication. A triadic sequence is identified as the elementary unit for the intersubjective constitution of an act. This unit combines three achievements: (a) the constitution of meaning by sequential attribution, (b) the intersubjective coordination of attributed meanings, and (c) the reproduction of rules, guiding the process of constitution and coordination of attributed meanings. Then, using the tools of systems theory and applying them to empirical results of ethnomethodology and conversation analysis, it is shown how the rule scheme is integrated in a triadic sequence, functioning on three different levels of communication. Finally, a specific form of repair after next turn is discussed, relating it to the function of preserving the structure of conversational types. The analysis of such conversational types opens a possible realm of cooperation between conversation analysis and Luhmann's version of systems theory. 相似文献

Patterns of mean-level change in personality traits across the life course: a meta-analysis of longitudinal studies 总被引:9,自引:0,他引:9
The present study used meta-analytic techniques (number of samples = 92) to determine the patterns of mean-level change in personality traits across the life course. Results showed that people increase in measures of social dominance (a facet of extraversion), conscientiousness, and emotional stability, especially in young adulthood (age 20 to 40). In contrast, people increase on measures of social vitality (a 2nd facet of extraversion) and openness in adolescence but then decrease in both of these domains in old age. Agreeableness changed only in old age. Of the 6 trait categories, 4 demonstrated significant change in middle and old age. Gender and attrition had minimal effects on change, whereas longer studies and studies based on younger cohorts showed greater change. 相似文献

The Wada test is at present the method of choice for preoperative assessment of patients who require surgery close to cortical language areas. It is, however, an invasive test with an attached morbidity risk. By now, an alternative to the Wada test is to combine a lexical word generation paradigm with non-invasive imaging techniques. However, results of this approach are still not in complete agreement with the findings of the Wada test (r = .92; Knecht, Deppe, Ebner et al., 1998). We attempted to obtain a more distinct language lateralization with the development of a phonological rhyme generation paradigm based on pseudoword stimuli. To examine the predictive value of both paradigms we performed simultaneous bilateral functional transcranial Doppler ultrasonography on 19 right-handed male native German subjects. The rhyme generation condition produced a significantly stronger lateralization to the supposed hemisphere of language dominance than the classical word generation condition. The observed differences suggest that the rhyme generation paradigm is more robust in detecting hemispheric language dominance than other neuropsychological paradigms and might be most valuable for preoperative assessment of cortical language areas. 相似文献

The purpose of the following study is to identify characteristics of the clinical treatment of patients who came into a crisis during an out-patient psychotherapy and were admitted to a crisis intervention ward. Most of the patients particularly reacted to a disruption of the treatment process as a result of conflicts in their relationship with their therapists. By means of a psychodynamic short diagnostics these conflicts were elucidated although they were often hidden and had to be traced back to their origins in the therapeutic relationship. Moreover, the authors describe their therapeutic focus on the conflict-solution-oriented short-term psychotherapy of the disruption of the therapeutic bond between patient and therapist which leads to a fixation of the setting. The in-patient crisis intervention aims at preparing the patients to continue the out-patient psychotherapy. 相似文献
