Impact of emotional content on discourse production in patients with unilateral brain damage. 总被引:1,自引:0,他引:1
A picture story task was developed to examine expression of emotion via the verbal/lexical channel. The task elicited discourse with either emotional, visual-spatial, or neutral content and was administered to right brain-damaged (RBD), left brain-damaged (LBD), and normal control (NC) right-handed adults. Subjects were matched for gender, age, education, and occupational status. The brain-damaged groups were matched for months post-CVA onset and were similar with respect to intrahemispheric site of lesion. While the number of words produced was equivalent for each of the subject groups, the RBDs and LBDs expressed quantitatively less content than did the NCs. When content differences were examined within each subject group, there were no differences for LBDs and NCs, but the RBDs showed a selective deficit when producing emotional content. This finding suggests a special role for the right hemisphere in the production of emotional content in verbal discourse. 相似文献

A test of a passive self-control training procedure suggested by Skinner was performed. After smoker's tolerance for delay of smoking was assessed, they were exposed to either an increasing, decreasing or random sequence of imposed delay of smoking and were then tested for tolerance to delay. Increasing delay significantly improved subjects' smoking inhibition while decreasing and random sequences had no significant effect. The results are attributed to either frustration extinction or rehearsal of coping responses to the aversiveness of delay. 相似文献

Discrimination of two types of simulated single-second-formant: frequency transitions was studied, transitions where members of a stimulus set shared the same onset frequency and transitions where stimuli of a set shared the same offset frequency. Experiment 1 employed an adaptive procedure to measure just-noticeable differences for transitions that increased in frequency. Experiment 2 obtained complete psychometric functions, based on a three-interval,forced choice procedure,for transitions that either increased or decreased in frequency. In both experiments, better discrimination occurred for longer stimuli, measured in hertz/millisecond, and for transitions that shared the same onset frequency. There were no differences, in Experiment 2, between discrimination of rising and falling transitions. Results are considered from several theoretical perspectives. 相似文献

The time course and the nature of social elicitation of vocalizations in 3-month-old infants were analyzed. Adult stimulation produced an immediate and significant increase in both the rate and the percent of bursts of vocal sounds of eight infants (Experiment 1). Both response-independent and response-dependent social stimulation were effective in producing increased rates of vocalizations, but only when each of four infants could see the eyes of the adult who delivered the social stimulus (Experiment 2). 相似文献

Groups of C57BL/6J mice were administred cycloheximide (CYC) 30 min before or immediately after training on a passive avoidance task and tested 72 hr later. Some CYC-pretreated groups were given strychnine or d-amphetamine (d-amp) immediately after training and others were given d-amp 1 hr after training. Other groups were given diethyldithiocarbamate (DDC) at various times before or after training. Some DDC-pretreated groups were gived-amp or strychnine as described above for CYC groups. Immediate posttraining administration of 5 mg/kg d-amp, but not strychnine, prevented amnesia in CYC-pretreated mice. The DDC induced an apparent amnesia when administered from 30 min before training to 3 hr after training. Posttraining administration of d-amp or strychnine did not prevent DDC-induced amnesia. These results are discussed in relation to previous suggestions that CYC- and DDC-induced amnesia may be the result of a functional impairment of catecholamine neurotransmitter systems by these drugs. 相似文献

Evaluations of the factors contributing to the quality and utility of sponsored research have indicated that characteristics of the researchers and funding arrangements tend to explain differences among projects. This article examines the validity of assumptions about the effects of organizational environment, funding level, and project duration on the outcome of funded research. The results of this study suggest a need to reexamine ideas about the determinants of research quality and utility, and implications for managers of research studies are drawn from the findings. 相似文献

Zimbardo's deindividuation hypothesis was reexamined by individuating some subjects. Twelve four-person groups administered shock to a confederate in a 2 × 2 × 2 factorial design with two levels of social individuation (subjects' level of anonymity to group members), two levels of nonsocial individuation (subjects' opportunity to give identifying information to the experimenter on a word association test), and two levels of individual differences. It was found that subjects who individuated themselves by giving information to the experimenter on the word association test showed more, not less, antisocial behavior. Furthermore, this increased antisocial behavior was exhibited only by externally oriented subjects: those with an external locus of control and a low mysticism score. Some of those more antisocial subjects were also more likely to report feeling like they stood out from the group. It was concluded that antisocial behavior in this paradigm may thus be a response to experimenter demand felt most strongly when subjects felt most identifiable. 相似文献

The suffix effect is the selective impairment in recall of the final items of a spoken list when the list is followed by a nominally irrelevant speech item, or suffix. It is widely assumed to comprise a bottom-up, or structural, effect restricted to the terminal item and a top-down, or conceptually sensitive, effect confined to the preterminal items. Reported here are eight experiments that challenge this view by demonstrating that the terminal suffix effect, as well as the preterminal suffix effect, is susceptible to conceptual influence. The entire suffix effect may be better conceived of as a phenomenon arising from perceptual grouping. 相似文献
