In decision research, it is widely assumed that decision makers have subjective experiences which indicate definitively, albeit with random fluctuations, whether or not one alternative is preferable to another. Further, it is assumed that subjects' choices reflect this underlying preference order. It follows from this position, as a logical consequence rather than an empirical observation, that if a manipulation affects people's choices, it does so by changing the way people subjectively experience the alternatives (presumably via people's encoding or combination of attribute information). In psychophysics, an analogous theoretical position has been relinquished. Specifically, it is no longer believed that observers in a detection experiment have subjective experiences which indicate definitively, albeit with error, whether a signal has been perceived. Rather, according to signal detection theory, the observer's sensory experience can be portrayed as a quantifiable sensation that must be converted into an overt report of “signal present” or “signal absent” by comparing the sensation with a criterion. In this paper, we describe two models of preferential choice, the lexicographic criterion model and a probabilistic criterion model, that replace the notion of definitive preference with an analogue of signal detection theory. In the models, the decision maker is represented as having quantifiable inclinations, rather than definitive preferences, that must be converted into an overt choice by comparing the inclinations with a criterion. By attributing the effects of experimental manipulations to shifts in the criterion, rather than to changes in people's inclinations, the model offers a testable alternative to the proposition that altered choices imply altered preferences. 相似文献

Abstract— The ability to predict future consequences on the basis of previous experience with the current yet of environmental cues is one of the most fundamental of all cognitive processes. Thix sttidv investigated how the validity of one cue influences the effectiveness of another cue for predicting a criterion. The results demonstrate a cue competition effect—increasing the validity of one cue decreased the effectiveness of another cue in a linear prediction task, even though the two cues were statistically independent. 相似文献

The present research was designed to investigate the proposition that repressors, operationally defined by the conjunction of low anxiety and high defensiveness, are particularly adept at avoiding the processing of information when motivated to do so. Four groups of participants (nondefensive-low anxious, high anxious, repressors, and defensive-high anxious) were administered a dichotic listening task involving neutral or negative affective words presented in the unattended ear. Participants shadowed the material presented to the attended ear and simultaneously responded to a probe task presented on a video monitor. Results revealed that repressors made significantly fewer shadowing errors than high anxious and defensive-high anxious participants and marginally significantly fewer shadowing errors than low anxious participants for both neutral and negative words. High anxious participants, however, were later able to recognize the negative words that had been presented to the unattended ear at well above chance levels, whereas the recognition memory of repressors for such negative unattended words was at chance levels. In addition, repressors' responses to a postexperiment questionnaire indicated a significantly greater number of distracting thoughts during the experiment relative to other participants. Repressors, it seems, are indeed skillful at avoidant information processing and this capacity may well be related to the emotional memory deficits they have displayed in previous research. 相似文献

Six psychiatry inpatients were observed during mealtimes to determine and evaluate staff intervention techniques. To extend and further elaborate the findings of a previous work (Pines, Kupst, Natta, & Schulman, 1985), staff behaviors (positive, punitive, isolating, and neutral) were investigated for their potential relationship to subsequent child behaviors (positive, negative, and inactive) via a lag sequential analytic approach. Staff punitive and isolating behaviors tended to be associated with significant increases in the likelihood of subsequent child negative behaviors and with significant decreases in child positive behaviors. Staff positive behaviors tended not to be related to a subsequent increase or decrease in any of the coded child behaviors. Findings demonstrate the utility of assessing conditional probabilities of sequences of staff-child behaviors in psychiatric inpatients. 相似文献

Self-assigned handles (nicknames) connote gender images in citizens band radio (CB), a limited-channel, mass participation speech community. Semantic differential analysis of a sample of male and female handles reveals that men project virility, while women collectively refrain from any significant degree of gender marking. Male dominance, absence of nonverbal communication channels, and the newness of the community combine to account for present image patterns.Research was supported by a grant from the University of South Florida Research Council.

The purpose of this study was to examine the change in work values which takes place during adolescence between the ninth and twelfth grades. The Occupational Values Inventory (OVI) was the instrument selected for use in the study. This instrument was previously developed as part of the longitudinal Vocational Development Study (VDS) project in the Department of Vocational Education at the Pennsylvania State University. The unique features of the OVI is that it is an ipsative instrument with a forced choice format containing work value statements with a seventh grade reading level. The major hypothesis of the study was that important changes do occur between ninth and twelfth grades and that these changes differ depending on the students' high school curriculum. The sample for the study were 659 high school students who were seniors in the Spring of 1972 and who had taken the OVI 3 yr previously when they were in ninth grade. The results of the study indicate that five of the seven OVI values did change over the 3-yr period and at least some of this change appeared to be related to the students high school curriculum. Other important findings observed were: (1) the “Salary” value experienced the greatest increase; (2) value intensity changed so that strong values grew stronger and weak values weaker; (3) the Home Economics curriculum which is totally female experienced almost no change in work values while all other curriculums change on at least three values. 相似文献

Summary Albino rats under either a daily high (2 gms) or moderate (12 gms) food deprivation condition were presented stimuli at the termination of reinforced fixed ratio bar press response chains. Within each drive group, half the animals received a session of brief light-off stimuli accompanied by reinforcement followed by a session of a buzzer and light-off compound stimuli paired with reinforcement. The remaining animals had the buzzer first paired with reinforcement and then the compound stimulus paired with reinforcement. Each stimulus element was tested for its respective control of nonreinforced food-cup approach behavior. These tests demonstrated that the buzzer cue blocked and overshadowed control of approach behavior of the light-off cue. In animals that received the initial light-off conditioning session, overshadowing by the buzzer of the light-off stimulus was less strong in high than moderate drive animals. These results were discussed in terms of Kamin's (1969) findings and Easterbrook's (1959) arousal-cue utilization hypothesis.The present study was supported by a grant given to the senior author from the National Research Council of Canada (APA 7450). The findings of the single stimulus control groups were also presented as a paper in modified form to the Canadian Psychological Association at its annual meeting, 1974, Windsor, Ontario, Canada. 相似文献
