This study explored the differences on personality variables between upperclass students who made congruent and incongruent occupational choices. The personality variables were operationally defined by the California Psychological Inventory and the Omnibus Personality Inventory. Congruent and incongruent current occupational choice groups were defined operationally using the Self Directed Search. The analysis of variance revealed the main effect of groups to be significant for nine personality variables. The test for the main effect of sex was found to be significant for seven personality variables. The test for interaction was found to be significant for three personality variables. Findings suggest that students in the congruent male group tend to report better maintenance of personal and vocational stability and greater satisfaction than students in the incongruent male and female groups. 相似文献

After rats were trained to lever press, response elimination began with factorial combinations of fixed vs variable and adjusting vs constant omission training schedules. A time interval scheduling reinforcement remained the same in a constant schedule, and its length was increased as response rate declined in the adjusting schedule. A variable time (VT) response-independent reinforcement schedule followed response elimination to test the durability of response cessation. Experiment I included groups whose reinforcement was yoked to that received by the omission schedule groups. Rate of response elimination was faster with an adjusting than a constant schedule, and slightly faster with a variable than a fixed schedule. There were no significant differences in rate of response elimination between omission schedule and yoked groups. Shorter delay of reinforcement tended to increase rate of response elimination. In the subsequent VT durability test all groups displayed near-zero response rates. In Experiment II adjusting fixed and variable omission schedules, including yoked groups, were compared with fixed time (FT) and VT reinforcement schedules. Response elimination was slower in the FT and VT groups, and they responded more in a subsequent VT durability test. It was concluded that differential reinforcement of other behavior fails to account for these omission training effects, and suggestions were made for an analysis based on the correlation between response and reinforcement rate. 相似文献

This study contrasted the gains made in speech theraphy by 39 stutterers, 15 of whom were treated by conventional methods and 24 by the Probe technique. It was found that the Probe technique yielded substantially greater gains in fluency than did the conventional method, having more influence on final performance than factors such as initial fluency, time since onset of stuttering, or the presence of other unacceptable behaviors. 相似文献

This study assessed various determinants of adolescents' comprehension of televised sexual innuendos. Eighteen males and 18 females at each of three ages (12, 14, and 16 years) were asked to interpret a series of 24 TV excerpts, each of which contained either a sexual innuendo or a nonsexual filler joke. Based on adult ratings, the innuendos were systematically varied by the topic alluded to (intercourse, physical/sexual attributes, socially discouraged practices, and nonsexual) and the level of explicitness (high vs. low). Age of viewer and topic referenced significantly influenced the comprehension scores. Fourteen- and sixteen-year-olds yielded higher scores than twelve-year-olds. Innuendos referencing discouraged sexual practices were most adequately explained and those referencing intercourse were least adequately explained. 相似文献

Various behavioral CRs elicited by saccharin solution previously paired with either lithium or amphetamine were measured in a series of four experiments. With one conditioning trial, lithium (Experiment 1), but not amphetamine (Experiment 2), produced nonconsummatory behavioral evidence of conditioning in the form of chin-rub CRs; both drugs, however, produced strong flavor aversions. With 3 conditioning trials, lithium- and amphetamine-paired flavors elicited a pattern of agitated activity, characterized by increased general activity, rearing duration, and body temperature, when the flavor was forcibly presented through an intraoral cannula (Experiment 3). When the flavor was presented in a single-bottle test (Experiment 4), 3 conditioning trials produced a similar pattern of agitated activity characterized by increased general activity, rearing (duration and frequency), stretching (duration and frequency), and limb flicking. Although both drugs supported the pattern of increased agitation-related CRs, only the lithium-paired flavors elicited chin-rub CRs (Experiments 1, 3, and 4). The difference between the drug conditions was not the result of a greater saccharin aversion in the lithium-conditioned group than in the amphetamine-conditioned group (Experiment 4). The results are related to findings that suggest that flavor aversions are mediated by a shift in the hedonic properties of the drug-paired flavors. 相似文献

A series of three experiments was run to test the hypothesis that when animals are exposed to a cue from prior training, the context in which cueing occurs becomes associated with the training memory. The first experiment demonstrates that when rats are trained to avoid in one context and then are tested in a different context performance is reduced. Experiments 2 and 3 demonstrate that this performance deficit can be alleviated by cueing the rats in the test context prior to testing. The data suggested that the improved performance does not seem to result from the association of the cueing context with a fear response. These results are discussed in relation to the context addition hypothesis. 相似文献

A confusion model is defined as a model that decomposes response probabilities in stimulus identification experiments into perceptual parameters and response parameters. Historically, confusion models fall into two groups. Models in Group I, which includes Townsend's (Perception and Psychophysics, 1971, 9, 40–50) overlap model, were developed on the basis of the notion that stimulus identification is mediated by a finite number of internal states. We call the general class of models that have this processing interpretation finite state confusion models. Models in Group II, which includes Luce's (R. O. Luce et al., Eds., Handbook of Mathematical Psychology (Vol. I), New York: Wiley, 1963) biased choice model, were not developed on the basis of an explicit processing interpretation. It is shown here that models in Group II are not finite state confusion models. We prove in addition that except for Falmagne's (Journal of Mathematical Psychology, 1972, 9, 206–224) simply biased model models in Group II belong to a certain class of infinite state confusion models, namely, models asserting that stimulus identification is mediated by a continuous space of vectors representing detector activation levels. 相似文献

A new theory of preferences under risk is presented that does not use the transitivity and independence axioms of the von Neumann-Morgenstern linear utility theory. Utilities in the new theory are unique up to a similarity transformation (ratio scale measurement). They key to this generalization of the traditional linear theory lies in its representation of binary preferences by a bivariate rather than univariate real valued function. Linear theory obtains a linear function u on a set P of probability measures for which u(p) > u(q) if and only if p is preferred to q. The new theory obtains a skew-symmetric bilinear function φ on P × P for which φ(p, q) > 0 if and only if p is preferred to q. Continuity, dominance, and symmetry axioms are shown to be necessary and sufficient for the new representation. 相似文献

Four experiments demonstrate that infants of 5 and 7 months can detect information that is invariant across the acoustic and optic presentations of a single affective expression. Infants were presented simultaneously with two filmed facial expressions accompanied by a single vocal expression characteristic of one of the facial expressions. The infants increased their looking time to a facial expression when it was sound-specified, as compared to when that filmed expression was projected silently. Even when synchrony relations were disrupted, infants looked proportionately longer to the film that was sound-specified, indicating that some factor other than temporal synchrony guided the infants' looking behavior. When infants viewed the filmed facial expressions either in a normal orientation or upside-down, those infants viewing the facial expressions in the normal orientation looked appropriately, while those viewing the inverted films did not. These findings support the view that infants are sensitive to amodal, potentially meaningful invariant relations in expressive behaviors. These results are discussed in the context of J. J. Gibson's theory of affordances. 相似文献
