This series of studies identified individuals who chronically believe that they can successfully defend their attitudes from external attack and investigated the consequences of this individual difference for selective exposure to attitude-incongruent information and, ultimately, attitude change. Studies 1 and 2 validated a measure of defensive confidence as an individual difference that is unidimensional, distinct from other personality measures, reliable over a 2-week interval, and organized as a trait that generalizes across various personal and social issues. Studies 3 and 4 provided evidence that defensive confidence decreases preference for proattitudinal information, therefore inducing greater reception of counterattitudinal materials. Study 5 demonstrated that people who are high in defensive confidence are more likely to change their attitudes as a result of exposure to counterattitudinal information and examined the perceptions that mediate this important phenomenon. 相似文献

Both coherent perspective jitter and explicit changing-size cues have been shown to improve the vection induced by radially expanding optic flow. We examined whether these stimulus-based vection advantages could be modified by altering cognitions and/or expectations about both the likelihood of self-motion perception and the purpose of the experiment. In the main experiment, participants were randomly assigned into two groups-one where the cognitive conditions biased participants towards self-motion perception and another where the cognitive conditions biased them towards object-motion perception. Contrary to earlier findings by Lepecq et al (1995 Perception 24 435-449), we found that identical visual displays were less likely to induce vection in 'object-motion-bias' conditions than in 'self-motion bias' conditions. However, significant jitter and size advantages for vection were still found in both cognitive conditions (cognitive bias effects were greatest for non-jittering same-size control displays). The current results suggest that if a sufficiently large vection advantage can be produced when participants are expecting to experience self-motion, it is likely to persist in object-motion-bias conditions. 相似文献

Systems psychodynamics: the formative years of an interdisciplinary field at the Tavistock Institute
Fraher AL 《History of psychology》2004,7(1):65-84
Systems psychodynamics is an interdisciplinary field amalgamating a triad of influences -the practice of psychoanalysis, the theories and methods of the field of group relations, and the task and boundary awareness of open systems perspectives. Although systems psychodynamics is not a new field of study, there has been a general lack of awareness of its roots, how its formative elements have become intertwined over the years, and the role of the Tavistock Institute in developments in the field. This article provides a synthesis of this history and focuses, in particular,on the intellectual foundations of the Tavistock method of working experientially with groups and the application of this method to the study of organizations. 相似文献

A policy-capturing study of the simultaneous effects of fit with jobs,groups, and organizations 总被引:8,自引:0,他引:8
The authors report an experimental policy-capturing study that examines the simultaneous impact of person-job (PJ), person-group (PG), and person-organization (PO) fit on work satisfaction. Using hierarchical linear modeling, the authors determined that all 3 types of fit had important, independent effects on satisfaction. Work experience explained systematic differences in how participants weighted each type of fit. Multiple interactions also showed participants used complex strategies for combining fit cues. 相似文献

EFFECTS OF D‐AMPHETAMINE IN A TEMPORAL DISCRIMINATION PROCEDURE: SELECTIVE CHANGES IN TIMING OR RATE DEPENDENCY?

Two experiments evaluated rate dependency and a neuropharmacological model of timing as explanations of the effects of amphetamine on behavior under discriminative control by time. Four pigeons pecked keys during 60-trial sessions. On each trial, the houselight was lit for a particular duration (5 to 30 s), and then the key was lit for 30 s. In Experiment 1, the key could be lit either green or blue. If the key was lit green and the sample was 30 s, or if the key was lit blue and the sample was 5 s, pecks produced food on a variable-interval 20-s schedule. The rate of key pecking increased as a function of sample duration when the key was green and decreased as a function of sample duration when the key was blue. Acute d-amphetamine (0.1 to 3.0 mg/kg) decreased higher rates of key pecking and increased lower rates of key pecking as predicted by rate dependency, but did not shift the timing functions leftward (toward overestimation) as predicted by the neuropharmacological model. These results were replicated in Experiment 2, in which the key was lit only one color during sessions, indicating that the effects were not likely due to disruption of discriminative control by key color. These results are thus consistent with rate dependency but not with the predictions of the neuropharmacological model. 相似文献

Functional analyses revealed that peer attention was one variable maintaining the off-task behavior exhibited by 3 students with a diagnosis of attention deficit hyperactivity disorder (ADHD). Peer-mediated reinforcement plus prompting was then used to reduce off-task behavior in a simulated classroom environment. Implications for future applications of this procedure with children diagnosed with ADHD are discussed. 相似文献

Mixed lists of associatively related and unrelated paired associates were used to study monitoring of associative learning. Older and younger adults produced above-chance levels of relative accuracy, as measured by intraindividual correlations (gamma) of judgments of learning (JOLs) with item recall. JOLs were strongly influenced by relatedness, and this effect was greater for older adults. Relative accuracy was higher for unrelated than for related pairs. Correlations of JOLs with item recall for a randomly yoked learner indicated that access to one's own encoding experiences increased relative accuracy. Both age groups manifested a contrast effect (lower JOLs for unrelated items when mixed with related items). Aging appears to spare monitoring of encoding, even though it adversely affects associative learning. 相似文献
