Age differences in short-term retroactive interference, unconfounded with age differences in rehearsal in the retention interval of the Brown-Peterson Task, were not found in a cross-sectional study of adults 18-32 and 64-78 years of age. Degree of retroactive interference was manipulated conjointly with distractor interval length (0-15 s). Individual memory span was assessed and used as the list length in order to achieve stimulus equivalence of memory loads across individuals and age groups. An attention-demanding matching task that adjusted itself in difficulty to the individual's attentional capacity was used as the distractor activity. Covert rehearsal during the retention interval was inferred using several measures, including a comparison of distractor task performance in the presence and in the absence of a memory load, and rehearsers were excluded from the primary analyses. We conclude that there is no interference proneness with increasing age in the present study. 相似文献

Young and older adults were presented with pictures for study. Their recognition of the information was tested at five retention intervals: immediately, and 48 hr, 1 week, 2 weeks, and 4 weeks later. The main finding of interest was that picture recognition did not show an age-related decline until the 1-week retention interval. 相似文献

Legal and nonlegal factors influencing the civil commitment recommendations of psychologists and psychiatrists separately and as a whole were investigated using an experimental design. One hundred and seventy-six psychologists and psychiatrists made recommendations for or against commitment for a series of clinical vignettes wherein the five facets of commitment criterion, legal committability, clinical treatability, alternative resources and presence of psychosis were systematically varied. Results revealed that all facets contributed independently and in combination to the commitment decisions of participants as a whole. It was concluded that mental health professionals may utilize a variety of types of information, beyond the relevant legal criteria, in making actual decisions to initiate civil commitments. 相似文献

A computer-controlled system that detects spontaneous activity (locomotion and rearing) and diurnal activity rhythms in small animals is described. Automatic recording of subtotals during test periods provides data about habituation (nonassociative learning). The system is relatively inexpensive to construct. Fabricated from highly reliable circuit components, it provides replicable measures that enable comparisons between different experimental treatments to be made using parametric statistics. 相似文献

Mackenzie, this journal, this issue, convincingly shows that in certain dialogue games (commitment games) there are procedural restrictions similar to those that I impose on rationality idealizations. But, whereas my rationality analysis is set in the context of belief games, commitment games do not postulate beliefs. Is this significant? I suggest that mackenzie thinks that it is. There follow discussions of Psychologism and Behaviourism. 相似文献

Males were randomly assigned to view either (1) a film clip featuring hockey fights or (2) a film of nonaggressive hockey
action or (3) a no-film control condition after having first been angered or treated politely by an experimental confederate.
The dependent variable was represented by a measure of aggressive mood and a behavioral measure of retaliatory aggression.
Analyses revealed that both angered and nonangered subjects exhibited an increase in aggressive mood following exposure to
the fight film. However, the analysis involving retaliatory aggression against the confederate yielded an anger x film interaction.
While angered subjects were more aggressive than nonangered, only angered subjects retaliated against the confederate after
viewing the fight film. The results were discussed in terms of Berkowitz’s (1974) aggressive cue theory.
A version of this paper was presented at the meeting of the North American Society for the Sociology of Sport, Edmonton, Canada,
November 1987. 相似文献
