Do dissociations imply independent systems? In the memory field, the view that there are independent implicit and explicit memory systems has been predominantly supported by dissociation evidence. Here, we argue that many of these dissociations do not necessarily imply distinct memory systems. We review recent work with a single-system computational model that extends signal-detection theory (SDT) to implicit memory. SDT has had a major influence on research in a variety of domains. The current work shows that it can be broadened even further in its range of application. Indeed, the single-system model that we present does surprisingly well in accounting for some key dissociations that have been taken as evidence for independent implicit and explicit memory systems. 相似文献

Relocation is an increasingly prominent conservation tool for a variety of wildlife, but the technique also is controversial,
even among conservation practitioners. An organized framework for addressing the moral dilemmas often accompanying conservation
actions such as relocation has been lacking. Ecological ethics may provide such a framework and appears to be an important
step forward in aiding ecological researchers and biodiversity managers to make difficult moral choices. A specific application
of this framework can make the reasoning process more transparent and give more emphasis to the strong sentiments about non-human
organisms held by many potential users. Providing an example of the application of the framework may also increase the appeal
of the reasoning process to ecological researchers and biodiversity managers. Relocation as a conservation action can be accompanied
by a variety of moral dilemmas that reflect the interconnection of values, ethical positions, and conservation decisions.
A model that is designed to address moral dilemmas arising from relocation of humans provides/demonstrates/illustrates a possible
way to apply the ecological ethics framework and to involve practicing conservationists in the overall decision-making process. 相似文献

B. F. Skinner and T. N. Whitehead recalled a personal interaction in 1934, with differing memories of the event. No evidence of other subsequent interactions or mutual citations has been found. Although they went their separate ways, three similarities in their research strategies have been found and are discussed. Elements of Whitehead's Hawthorne study and Skinner's concurrent, parallel work reveal that they both (a) introduced the cumulative curve to report data, (b) used a small number of subjects studied over time, and (c) used highly accurate recording devices. A few "afterwords" are offered on their lives and writings, and again, on the Hawthorne effect. A suggestion is made that a Skinner-Whitehead research approach might be useful in studying gambling behavior. 相似文献

Theoretical and empirical evidence distinguishes between two types of response distortion: impression management (IM) and self‐deceptive enhancement (SDE), although most research in Industrial/Organizational Psychology has focused on the effects of IM. The present study compared the effects of IM and SDE on job performance and personality validity. Two‐hundred and sixty‐one managers completed Big Five Personality, SDE, and IM measures. The managers' supervisors, peers, and subordinates rated their job performance. In accordance with previous research, accounting for managers' IM scores did not increase prediction of job performance. On the other hand, accounting for SDE did increase prediction. Increased prediction was due to an interaction between Extraversion and SDE, and an increase in the predictive validity of Emotional Stability when SDE was held constant. Results suggested that findings from previous research demonstrating that IM does not affect job performance or personality validity cannot be extended to SDE. 相似文献

The purpose of this research report is to highlight a unique set of issues that arise when considering the effects of range restriction in the context of estimating predictor intercorrelations. Three approaches are used to illustrate the issue: simulation, a concrete applied example, and a reanalysis of a meta-analysis of ability-interview correlations. The general conclusion is that a predictor intercorrelation can differ dramatically from the population value when both predictors are used in a composite that is used operationally for selection. The compensatory nature of a composite means that low scorers on one predictor can only obtain high scores on the composite if they obtain very high scores on the other predictor; this phenomenon distorts the correlation between the predictors. 相似文献

OBJECTIVE: To determine the percentage of family caregivers of persons with spinal cord injury (SCI) with probable depression and to test the hypothesis that dysfunctional problem-solving abilities would be significantly predictive of risk status after taking into account important demographic characteristics and caregiver health. DESIGN: Correlational and logistic regression analyses of data collected in a cross-sectional design. PARTICIPANTS: Eighteen men and 103 women caregivers (mean age of caregivers = 45.66 years, SD = 12.88) of individuals with SCI. MAIN OUTCOME MEASURE: The Inventory to Diagnose Depression. RESULTS: Nineteen caregivers (15.7%) met criteria on the Inventory to Diagnose Depression for a major depressive disorder. A dysfunctional problem-solving style was significantly predictive of caregiver depression, regardless of the severity of physical impairment of the care recipient or the physical health of the caregiver and caregiver demographic variables. CONCLUSIONS: The percentage of caregivers with probable depressive disorder may parallel that observed among persons with SCI, using a more conservative self-report measure designed to assess symptoms associated with a depressive syndrome. Family caregivers with a dysfunctional problem-solving style and assisting individuals with more severe injuries may have probable depression. 相似文献

Still clever after all these years: searching for the homunculus in explicitly cued task switching 总被引:1,自引:0,他引:1
Logan GD Schneider DW Bundesen C 《Journal of experimental psychology. Human perception and performance》2007,33(4):978-994
Many researchers interpret switch costs in the explicit task-cuing procedure as reflecting endogenous task-set reconfiguration. G. D. Logan and C. Bundesen (2003) challenged this interpretation empirically and theoretically. They argued that many experiments confounded cue encoding benefits with switch costs and they showed that unconfounded switch costs could be vanishingly small. They proposed a theory in which subjects use a single task set in the explicit task-cuing procedure and switch costs reflect cue encoding benefits, not reconfiguration. S. Monsell and G. A. Mizon (2006) responded to these challenges, describing conditions under which substantial switch costs could be observed in the explicit task-cuing procedure and providing a theoretical account of performance in which reconfiguration occurred in G. D. Logan and C. Bundesen's experiments. This article is a response to S. Monsell and G. A. Mizon's challenge that highlights empirical problems with their evidence and reports an experiment that challenges critical assumptions of their theoretical account. 相似文献

The exact variance of weighted kappa with multiple raters 总被引:1,自引:0,他引:1
Weighted kappa described by Cohen in 1968 is widely used in psychological research to measure agreement between two independent raters. Everitt then provided the exact variance for weighted kappa for two raters. In this paper, Everitt's exact variance is extended to three or more raters. 相似文献

We conducted a comprehensive analysis of assortative mating (i.e., the similarity between wives and husbands on a given characteristic) in a newlywed sample. These newlyweds showed (a) strong similarity in age, religiousness, and political orientation; (b) moderate similarity in education and verbal intelligence; (c) modest similarity in values; and (d) little similarity in matrix reasoning, self- and spouse-rated personality, emotional experience and expression, and attachment. Further analyses established that similarity was not simply due to background variables such as age and education and reflected initial assortment (i.e., similarity at the time of marriage) rather than convergence (i.e., increasing similarity with time). Finally, marital satisfaction primarily was a function of the rater's own traits and showed little relation to spousal similarity. 相似文献
