In three experiments we studied the relationship between contextual conditioning and the reinstatement of extinguished lever pressing that occurs when noncontingent food is introduced following extinction. In all three experiments the non-contingent food was presented off-baseline (with the response levers not present). On subsequent tests, with the response levers present, animals that had been exposed to food showed more reinstatement of lever pressing than control animals. This finding rules out alternative mechanisms for the reinstated responding that rely on the interaction of non-contingent food and responding, such as superstitious reinforcement or the discriminative after-effects of food. In addition, in each experiment we demonstrated that manipulations known to affect contextual conditioning (signalling the food in Experiment 1, context extinction in Experiment 2, and switching contexts in Experiment 3) reduced the reinstatement. These results are consistent with the claim that contextual conditioning is important in controlling instrumental conditioning and closely parallel findings concerning the reinstatement of Pavlovian responsing following extinction. 相似文献

This study examined information communication technologies and workplace friendship dynamics. Employees reported factors that influenced their initiation of friendship with a coworker and reported patterns and perceptions of communication with their workplace friend via different communication methods. Results indicated that personality, shared tasks, and perceived similarity are the most important factors to coworker friendship initiation, and the importance of physical proximity to workplace friendship is diminishing in the electronically connected workplace. Results confirm the primacy of face‐to‐face interaction for workplace friendship initiation and maintenance. E‐mail, phone, and texting were also central to communication among workplace friends. The amount of time spent telecommuting affected workplace friendship initiation and communication. Finally, generational differences were identified with respect to Internet‐based communication methods. 相似文献

The current study meta-analyzes 59 male-female pairs of validity coefficients obtained during revalidation of the General Aptitude Test Battery (GATB) for evidence of differential validity by sex. Results suggest that general cognitive ability may be slightly more predictive of rated job performance for women than for men in our sample of studies. Moderator analyses examined the effects of occupational sex-dominance and cognitive complexity. Results of these analyses indicate that, in single sex-dominated occupations, tests of general cognitive ability and perceptual ability are more valid for members of the dominant sex, and these differences are more apparent at low-complexity levels. Explanations for the findings are offered in terms of properties of the ratings criterion.An earlier version of this paper was given at the 2nd annual convention of the Society for Industrial and Organizational Psychology, Inc., Atlanta, GA. The authors thank Dave Synk for providing the occupation codes for each study. 相似文献

A number of studies have demonstrated stable individual differences in the cues that generate emotions and other feeling states. These differences are assumed to arise from the cues parents use to identify their children's emotional states. As children learn about their own emotional states, they come to rely on these same cues. To test one implication of their view, the facial expressions of children (N=41) were manipulated and their feelings assessed. Some children reported emotions consistent with their expressions, while others reported emotions appropriate to the situation. In a separate procedure, their mothers were asked to identify the emotional states of children whose expressions were inconsistent with an account of their circumstances. Mothers who paid more attention to their children's expressive behavior had children who were more responsive to their own expressive behavior. In contrast, the mothers who were more responsive to situational cues had children whose emotions arose from the situational cues as well.The authors would like to thank numerous teachers and administrators of the Worcester Public School system in Worcester, Massachusetts, for their assistance. 相似文献

A number of models for categorical item response data have been proposed in recent years. The models appear to be quite different.
However, they may usefully be organized as members of only three distinct classes, within which the models are distinguished
only by assumptions and constraints on their parameters. “Difference models” are appropriate for ordered responses, “divide-by-total”
models may be used for either ordered or nominal responses, and “left-side added” models are used for multiple-choice responses
with guessing. The details of the taxonomy and the models are described in this paper.

The FACTRETRIEVAL2 test battery, which assesses both retrieval of general information from memory and metacognition about that retrieval, was administered to people before and after a recent expedition to Mount Everest and at extreme altitudes above 6,400 m (higher than any mountain in North America or Europe). The major findings were as follows: First, the same extreme altitudes already known to impair learning did not affect either accuracy or latency of retrieval, and this robustness of retrieval occurred for both recall and forced-choice recognition. Second, extreme altitude did affect metacognition: The climbers showed a decline in their feeling of knowing both while at extreme altitude and after returning to Kathmandu (i.e., both an effect and an aftereffect of extreme altitude). Third, extreme altitude had different effects than alcohol intoxication (previously assessed by Nelson. McSpadden, Fromme, & Marlatt, 1986). Alcohol intoxication affected retrieval without affecting metacognition, whereas extreme altitude affected metacognition without affecting retrieval; this different pattern for extreme altitude versus alcohol intoxication implies that (a) hypoxia does not always yield the same outcome as alcohol intoxication and (b) neither retrieval nor metacognition is strictly more sensitive than the other for detecting changes in independent variables. 相似文献

An exploratory study of the values of inner-city postpartum women was conducted. Subjects were largely single, with many on/or going on public assistance. Each subject was given the Rokeach Value Scale and asked to prioritize the terminal values (goals) in terms of herself and the instrumental values (means) in terms of what she would like to teach her child. Rankings were compared to corresponding rankings compiled by a national sample, considered a more traditional era, and by marital status within the postpartum mother sample itself. Economic values were ranked higher by inner-city mothers than by the national sample. The top terminal value was family security and the top instrumental value was responsible. When compared by marital status, the only significant difference was the higher ranking of mature love given by married women. Results suggests that the values of the inner-city single postpartum mother can be conceptualized as a mosaic incorporating values shared with the mainstream and values adapted to the conditions of poverty. 相似文献

Policy recommendations that adolescents supplement their experience in school with experience in the workplace have been made in the absence of objective data on the nature of most adolescents' activity on the job. This paper presents a coding system for chronicling a variety of microbehaviors in sequence, as they occur, in adolescent job environments. Three elements of each of approximately 100 behaviors performed by a targeted teenage worker are recorded by an on-site observer who enters appropriate code numbers into a portable event recorder: (1) the social context of the behavior; (2) the character of the behavior; and (3) the duration and concomitants of the behavior, when appropriate. Each of 97 working teenagers was observed continuously over a two hour period on the job. Interobserver agreement on the coding of worker behaviors and the social contexts in which they occurred averaged .86 and .97, respectively. In addition to its applicability in research on the effects of working on adolescent development, information obtained using the code can be helpful in the evaluation of youth employment programs, the vocational counseling of adolescents, and the validation of subjective worker reports of job attributes. 相似文献
