These studies continue the exploration of variables related to a person's use of the mental illness categorization. The central concern in the present studies was the effect of perceived variation in a target person's level of involvement in a social situation. While a low level of involvement, as portrayed in videotaped scenarios, prompts attribution of mental illness, other features of implicit personality theories also relate to greater or lesser attribution of mental illness. Those participants who gave evidence of having attributed lower levels of involvement, regardless of filmed information, also attributed higher levels of mental illness. Social workers, compared to general population participants, attributed higher levels of mental illness at all levels of target involvement. We discuss the implications of these findings for dissemination and assignment of the mentally ill role. 相似文献

Male and female adult Ss, while performing an unrelated task, heard a single infant awakening. The infant was labeled a girl or a boy. The dependent variable was how quickly Ss responded to the crying infant. Females responded more quickly to the girl than to the boy. Males responded equally slowly to boy and girl. A questionnaire on sex differences in fragility showed that females and males tend to disagree with the proposition that girls are more fragile than boys. Thus, the females' faster response to a crying girl cannot be accounted for by a belief in sex-differential fragility. Correlations between fragility beliefs and response times to an infant indicate that sex-differential belief-behavior relationships are not the same for males and females. 相似文献

In the multistage betting game (MBG), a decision maker (DM) is provided with some capital x which he is required to bet over m (m > 1) mutually exclusive and collectively exhaustive alternatives, each of which occurs with probability pi (pi > 0, i = 1,…, m; Σi = 1mpi = 1). If yi is bet on alternative i (yi ≥ 0, Σi = 1myi = x) and alternative i obtains, the DM's capital for the next stage is yiri, (ri > 0). The MBG lasts until either the DM loses his capital or N stages elapse, whichever comes first. Each of six subjects participated in six sessions consisting of several hundred 3-alternative MBG stages. A within-subject design assigned negative expected value (EV) bets to the first three sessions and positive EV bets to three more sessions. Significant effects were found due to return rate, capital size, homogeneous runs of either wins or losses, and individual differences. Four maximization of expected utility and two minimization of risk models were presented and tested. A modified logarithmic utility model is proposed, which provides the best fit to the data. The implications of the results and directions for further research are briefly discussed. 相似文献

The effect of information relevance and information availability on perceptual differences between Chinese and American nationals was investigated. Subjects participated in pairs as decision makers in a complex experimental environment. Participants' perceptions of success, failure, and competence levels for their own team (under conditions where judgments could be based on varying levels of relevant information) and for a supposed opposing team (under conditions where perceptions had to be inferred in the absence of information) were obtained. It was found that Americans and Chinese did not differ in ratings of their own team. Chinese, as opposed to Americans, perceived the opposing team as having more success, less failure, and more competence. The perceptual errors of the French and Viet Minh which led t o the defeat of the French at Dien Bien Phu were replicated in the laboratory for Americans and Chinese. Areas in which such potential cultural (oriental versus occidental) differences might be important are mentioned. 相似文献

An optional reversal-nonreversal shift task for which the relevant color or form cues were either dominant or nondominant was presented to 320 Ss, 6 through 20 years of age. Dominance, as defined in terms of relative cue similarity, was related to initial learning and shift behavior for kindergarten and third-grade Ss; but not for sixth-grade and college Ss. The speed of initial learning and percentage of reversal shifts was related to age when the nondominant dimension was relevant. There were no developmental differences when the dominant dimension was relevant. 相似文献

Eight pigeons were tested for head nystagmus in a rotating drum with vertical black and white bars on the reside. When the birds viewed monocularly, they gave about four times as many responses to nasalward as to temporalward movement. However, no such asymmetry was observed in a discrimination paradigm. Six pigeons were taught binocularly to discriminate moving lines, which moved equally often to left and fight, from stationary fines. They were then tested monoculaxly, and the discrimination was controlled about equally by nasalward and temporalward movement. 相似文献

Following a suggestion by Shepard and Chipman (1970), photographs and names of 15 well-known faces were used as stimuli in judgments of similarity. Ss ranked all pairs of stimuli in terms of facial similarity either from memory when presented with pairs of names, or from photographs. There was a highly significant positive correlation between these two types of judgment. A simple classificatory analysis of the 15 faces in terms of the physical features provided evidence that judgments based on the internal representation of the faces utilized pictorial information. These results extend the generality of Shepard and Chipman’s findings and confirm the usefulness of an approach to the problem of mental images based on the concept of second-order isomorphism. 相似文献

Chlorpromazine (0.5-3.0 mg/kg) significantly reduced orienting to a novel auditory stimulus, but subsequent habituation after repeated presentations of the stimulus was not prevented nor significantly impaired. These results support the suggestion that the mechanisms underlying orienting and habituation are independent. 相似文献

Seventy-two male albino rats were trained to perform an instrumental running response, half at high deprivation and half at low. At Trials 23, 75, and 105 a third of the animals from each of the original groups were shifted to the opposite deprivation level. All shifts from high to low deprivation produced a significant decrease in performance; all shifts from low to high, a significant increase. After the early shift, performance was characterized by a residual effect of preshift deprivation level in which shifted groups gradually approached the new levels. After each of the later shifts, performance levels diverged sharply in what appeared to be both positive and negative contrast effects. The results were discussed in the framework of incentive motivation theory. 相似文献
