Research on the emergence of human avoidance behavior in the absence of direct contact with an aversive event is somewhat limited. Consistent with work on derived relational responding, the present study sought to investigate the transformation of avoidance response functions in accordance with the relational frames of Same and Opposite. Participants were first exposed to nonarbitrary and arbitrary relational training and testing in order to establish Same and Opposite relations among arbitrary stimuli. The training tasks were; Same-A1-B1, Same-A1-C1, Opposite-A1-B2, Opposite-A1-C2. Next, all possible combinatorially entailed (i.e., B-C and C-B) relations were tested. During the avoidance-conditioning phase, one stimulus (B1) from the relational network signaled a simple avoidance response that cancelled a scheduled presentation of an aversive image and sound. All but one of the participants who met the criteria for conditioned avoidance also demonstrated derived avoidance by emitting the avoidance response in the presence of C1 and the nonavoidance response in the presence of C2. Control participants who were not exposed to relational training and testing did not show derived avoidance. Implications of the findings for understanding clinically significant avoidance behavior are discussed. 相似文献

Although core, animal-reminder, and contamination disgust are viewed as distinct “types” of disgust vulnerabilities, the extent to which individual differences in the three disgust domains uniquely predict contamination-related anxiety and avoidance remains unclear. Three studies were conducted to fill this important gap in the literature. Study 1 was conducted to first determine if the three types of disgust could be replicated in a larger and more heterogeneous sample. Confirmatory factor analysis revealed that a bifactor model consisting of a “general disgust” dimension and the three distinct disgust dimensions yielded a better fit than a one-factor model. Structural equation modeling in Study 2 showed that while latent core, animal-reminder, and contamination disgust factors each uniquely predicted a latent “contamination anxiety” factor above and beyond general disgust, only animal-reminder uniquely predicted a latent “non-contamination anxiety” factor above and beyond general disgust. However, Study 3 found that only contamination disgust uniquely predicted behavioral avoidance in a public restroom where contamination concerns are salient. These findings suggest that although the three disgust domains are associated with contamination anxiety and avoidance, individual differences in contamination disgust sensitivity appear to be most uniquely predictive of contamination-related distress. The implications of these findings for the development and maintenance of anxiety-related disorders marked by excessive contamination concerns are discussed. 相似文献

Theories of self-regulation emphasize the special role that the symbolic self may play in approach and avoidance movements, but experimental evidence is lacking. In two experiments (total N = 157), participants moved either a self-relevant (e.g., “me”) or non-self (e.g., “not me”) agent to one of two locations, one occupied by a positive word and the other occupied by a negative word. In both experiments, the movement agent interacted with the destination valence such that it was only the symbolic self that moved more quickly to positive rather than negative locations. These results established a role for the symbolic self in approach/avoidance that had been questioned, thereby supporting both classic and contemporary self-related theories of approach and avoidance. 相似文献

Empowering leadership,uncertainty avoidance,trust, and employee creativity: Interaction effects and a mediating mechanism 总被引:1,自引:0,他引:1
Taking an interactional approach, we hypothesized that (a) there is an interaction between empowering leadership, uncertainty avoidance, and trust that affects creativity, such that empowering leadership has the strongest positive relationship with creativity when the employees have high levels of uncertainty avoidance and trust their supervisors; and (b) creative self-efficacy mediates the effect that this three-way interaction between empowering leadership, uncertainty avoidance and trust has on creativity. In Study 1, we used a time-lagged research design, collecting multi-source data from 322 employees and their supervisors. The results of Study 1 supported our hypotheses. In Study 2, we used a more temporally rigorous research design in which data were collected in three stages, with a two-month time interval separating Stages 1 and 2, and Stages 2 and 3. On the basis of the time-lagged and multi-source data from 199 employees and their supervisors, Study 2 produced the same results as Study 1. We discuss the implications of these results for future research and practice. 相似文献

A growing body of evidence points to links between internalizing symptoms and various executive functioning deficits, and especially to inhibition and set-shifting difficulties. However, there is limited developmental research regarding the impact of internalizing symptoms on the shifting function, particularly during middle childhood. The current study investigated attention shifting in a sample of 108 early school age children (7–11 years) using a task-switching paradigm which required participants to alternate between emotional and nonemotional judgments. Results indicated that higher levels of internalizing symptoms (anxiety and depression) had a detrimental effect on performance efficiency (measured by response times) but not on response accuracy. This effect was only observed on emotional (and not on nonemotional) repetition trials and did not affect switching trials; moreover, it was only present when feedback was presented to participants. The findings partially support the predictions of the Attentional Control Theory in a developmental sample and suggest that individual differences in internalizing symptoms play a role in children's ability to flexibly alternate between emotional judgments. 相似文献

High trait anxiety has been linked with risk-avoidant decision-making, though little is known regarding the specific facets of anxiety contributing to this negative association. Anxiety sensitivity (AS), a transdiagnostic vulnerability factor for anxiety-related pathology, may be particularly relevant to risk decision-making given that risk-taking behaviors generate heightened somatic arousal and produce many of the sensations feared by individuals with high AS. Two studies were conducted to investigate the relation between AS and risk decision-making. In the first study, 268 undergraduate students completed a series of questionnaires that included measures of AS and gambling behaviors. Significant negative correlations were observed between AS and several gambling-related risk-taking activities, and hierarchical multiple regression analyses indicated that AS scores added significant incremental validity in predicting risk-taking over and above demographic variables, negative affect, and trait anxiety. In the second study, 43 participants who had screened for high (n = 20) or low (n = 23) AS completed the Iowa gambling task, a behavioral measure of risk-taking. Results indicated that, when placed under conditions of risk, individuals with high AS engaged in significantly less risk-taking than their low AS counterparts. The implications of these findings and potential directions for future research are discussed. 相似文献

The purpose of the current study was to investigate the relationship between prospective memory (PM) and consciousness by examining cost to ongoing activities, with cost assumed to reflect a direction of conscious resources away from the ongoing task in service of the PM task. Ongoing task blocks in which the PM task was relevant or irrelevant were alternated to achieve three aims: determine if cost would persist in irrelevant blocks when relevant and irrelevant blocks were clearly demarcated and irrelevant stimuli were incompatible with the PM task; investigate if costs would be greatest at the start of irrelevant blocks; and determine whether costs would occur when the irrelevant block preceded any relevant blocks. Costs were found in irrelevant blocks and greater cost at the start of the irrelevant blocks suggest the cost may be due in part to participants making decisions about the engagement of conscious resources at transition points. 相似文献
