Four hundred nine high school students were surveyed to determine the percentage who had experienced suicidal ideation. The sample was then divided into high- and low-suicidal-risk groups. High-risk subjects were found to have significantly poorer quality friendships, lower self-esteem, and had experienced more life stress in the previous year. 相似文献

Three different stimulus modalities (line length, number, and sound pressure) were judged by magnitude scaling techniques and by 7-, 15-, 31-, and 75-point category scales. All of the 40 subjects were given the same number stimuli, but two different sound-pressure ranges were presented (each to 20 subjects) and four different line-length ranges were presented (each to 10 subjects). Analyses of lack of fit for various simple functions were performed to determine bestfitting functions. The simple power function was often found to be an adequate fit to the data for all the response modalities used, although all of the response modalities were sensitive to changes in stimulus range. For simple power functions, the category-scale exponent was a function of both the range of stimuli and the number of categories provided. Category scales did not always produce exponents smaller than those obtained with magnitude estimation, which calls into question the concept of a virtual exponent for category scales. 相似文献

The effect of time pressure on risky choice behavior 总被引:1,自引:0,他引:1
Thirty six subjects chose individually between pairs of gambles under three time pressure conditions: High (8 seconds), Medium (16 seconds) and Low (32 seconds). The gambles in each pair were equated for expected value but differed in variance, amounts to win and lose and their respective probabilities. Information about each dimension could be obtained by the subject sequentially according to his preference.The results show that subjects are less risky under High as compared to Medium and Low time pressure, risk taking being measured by choices of gambles with lower variance or lower amounts to lose and win. Subjects tended to spend more time observing the negative dimensions (amount to lose and probability of losing), whereas under low time pressure they preffered observing their positive counterparts. Information preference was found to be related to choices.Filtration of information and acceleration of its processing appear to be the strategies of coping with time pressure. 相似文献

Naive rats were trained to leverpress with a 30-sec delay-of-reinforcement contingency from the start of training. In Experiment
1, the delay interval for different groups of subjects included a signal in the first 5 sec, a signal in the last 5 sec, or
no signal at any time. Rats with the signal at the start of the delay interval learned most rapidly. Rats with the signal
at the end of the delay failed to learn. In Experiment 2, a choice procedure was used, in which each of two levers was associated
with its own 30-sec delay of reinforcement. The delay for one lever included a 5-sec signal at the end of the delay. The delay
for the second lever had no signal in its 30-sec delay. Preference was in favor of the lever without the signal in the delay
interval. The results demonstrate that the acquisition of new response can be blocked in a manner analogous to the blocking
of Pavlovian conditioning. 相似文献

Factor analysis of responses of funeral directors to work orientation items is interpreted first as specifying major orientational themes and second as to how well the theoretical value components of professionalism and a business orientation hold together empirically. The analysis revealed that the professionalism model as operationalized in this study has no single underlying dimension which would define this orientation. It is thus suggested that the meaning of professionalism be altered to refer only to involvement in the occupational structure and not include service and autonomy. The business orientation model, however, appears to be fairly well supported by the data. 相似文献

Four experiments investigated the dependence of persuasion on cognitive factors. All experiments employed a court case for which 795 subjects acted as jury members, reading summaries of both the prosecution and defense's testimony. The amount of objective information on both sides of the case was varied. Persuasion was a position function of the number of prosecution arguments and the number of defense arguments. This finding was extended by obtaining measures of the subjects'cognitive reactions to the case as well as their opinions and by following both of these measures over time. Both analysis of variance and multiple regression techniques showed that subjects could have derived their opinions from their cognitions about the case. This relationship also held up over time. These results suggest the general form of an information-processing theory of persuasion. One prediction of this theory is for an asymptotic function relating objective information to persuasion. This prediction received empirical support. 相似文献

A conceptual replication of the assigned-behavior conditions of previous research in attitude attribution was conducted. Participants made attitude attributions about themselves and also about others who had either given, listened to, or not been exposed to either a proattitudinal or counterattitudinal essay. The position adopted in the essay significantly affected the attitudes attributed to those assigned to deliver the essay. Essay position had an equally strong effect upon attitudes attributed to those who merely listened to the essay, however. Thus, the fact that the actor had delivered a particular assigned essay apparently did not in itself convey information to the observers about the actor's attitudes. Experimental results suggested that essay direction affects attitudes attitudes attributed to others in an assigned-behavior setting because observers use their own attitudes to infer the attitudes of others. Since observers' own attitudes change after exposure to different essays, they attribute different attitudes to others. 相似文献

The ethicist's role in the clinical context is not presently well defined. Ethicists can be thought of as moralists, technicians, Sophists, or as teachers and learners. Each of these roles is examined in turn. An argument is made for the ethicist as a teacher who must also learn a great deal about the clinical setting in order to encourage an effective critical examination of basic values. Four specific tasks of this teaching role are discussed: describing moral experience, eliciting assumptions, considering multiple alternatives and justifying choices. 相似文献
