Source memory may comprise recollection of multiple features of the encoding episode. To analyze the simultaneous representation and retrieval of those multiple features, a multinomial memory model is presented that measures memory for crossed dimensions of source information. The first experiment investigated the validity of the new model. The model showed an excellent statistical fit to empirical data, and the parameters of multidimensional source memory were sensitive to manipulations of source similarity on distinct dimensions. The second experiment used the model to test the hypothesis that source memory for individual context attributes is stochastically related in the case of conscious recollection but independent in the case of familiarity-based recognition judgments. The prediction was supported by the introduction of a "remember"-"know" distinction in a multidimensional source memory test. 相似文献

This paper tries to show that Kims strategy of preventing the problem of generalization of mental causation is not successful and that his original supervenience argument can be applied to cases of nonmental macrolevel causation, with the effect that nonmental macroproperties which only supervene on, but are not identical with, configurations of microproperties turn out to be epiphenomenal after all. 相似文献

When participants commit errors or receive feedback signaling that they have made an error, a negative brain potential is elicited. According to Holroyd and Coles’s (in press) neurocomputational model of error processing, this error-related negativity (ERN) is elicited when the brain first detects that the consequences of an action are worse than expected. To study age-related changes in error processing, we obtained performance and ERN measures of younger and high-functioning older adults. Experiment 1 demonstrated reduced ERN amplitudes in older adults in the context of otherwise intact brain potentials. This result could not be attributed to uncertainty about the required response in older adults. Experiment 2 revealed impaired performance and reduced response- and feedback-related ERNs of older adults in a probabilistic learning task. These age changes could be simulated by manipulation of a single parameter of the neurocomputational model, this manipulation corresponding to weakened phasic activity of the mesencephalic dopamine system. 相似文献

Evidence from 2 samples of Air Force mechanics supported the hypothesis that contextual performance affects employees' career advancement and rewards over time. Results of hierarchical regressions controlling for experience showed task performance and contextual performance each predicted systemic rewards. Each facet explained separate variance in promotability ratings over 2 years. In both samples, contextual performance explained separate variance in informal rewards but task performance did not. Task performance explained incremental variance in career advancement 1 year later but contextual performance did not. Analyses using correlations corrected for unreliability suggest these results cannot be attributed to measurement error. Contextual performance still explained separate variance in informal rewards, and task performance explained distinct variance in career advancement a year later. 相似文献

Replicated and extended aspects of determinations of reliability and validity for the State version of the Youth-Depression Adjective Check List. Students from Grades 9 through 12 (64 girls and 41 boys) completed the State version and the Adolescent Activities Checklist on each of 12 consecutive days and completed the Trait version, the Reynolds Adolescent Depression Scale, the Multiple Affect Adjective Check List--Revised Grade 6, and the Adolescent Activities Checklist at the beginning and the end of the study. Good reliability and validity of the State version were confirmed and extended, and preliminary information on characteristics of the Trait version of the Youth-Depression Adjective Check List also was presented. The State version seems suitable for use in research with adolescents and preadolescents. More study of the Trait version is recommended. 相似文献

In this paper early work of the American rehabilitation psychologist Tamara Dembo (1902-1993) is brought to light. She was highly influenced by the concepts of Kurt Lewin's topological psychology, and she used the framework of topological psychology to analyze her investigations on animal behavior carried out with the Dutch zoopsychologist Frederik J. J. Buytendijk. These investigations have so far been ignored and are being described for the first time making use of archival materials. 相似文献

We examined the differential impact of chronic versus acute economic stress on depressive mood among a sample of 1241 low-income, single, European and African American women. Based on Hobfoll's (1988, 1989) conservation of resources (COR) theory, we predicted that acute resource loss would be more distressing than chronic economic lack. That is, although chronically impoverished conditions are stressful, the attendant resource losses created will be more distressing. We further predicted that mastery and social support would be more beneficial in offsetting the negative consequences of acute resource loss than the negative consequences of chronic economic lack, because acute loss creates identifiable demands that resources may address. Hence, we hypothesized that mastery and social support would show stress buffering effects only for material loss, not chronic lack. The findings generally supported the hypotheses, but mastery buffered only European American women's resource loss and social support buffered only African American women's resource loss. The findings are discussed in light of implications for prevention within theoretical and cultural contexts. 相似文献

Two models, a Poisson race model and a diffusion model, are fit to data from a perceptual matching task. In each model, information
about the similarity or the difference between two stimuli accumulates toward thresholds for either response. Stimulus variables
are assumed to influence the rate at which information accumulates, and response variables are assumed to influence the level
of the response thresholds. Three experiments were conducted to assess the performance of each model. In Experiment 1, observers
performed under different response deadlines; in Experiment 2, response bias was manipulated by changing the relative frequency
ofsame anddifferent stimuli. In Experiment 3, stimulus pairs were presented at three eccentricities: foveal, parafoveal, and peripheral. We examined
whether the race and diffusion models could fit the response time and accuracy data through changes only in response parameters
(for Experiments 1 and 2) or stimulus parameters (for Experiment 3). Comparisons between the two models suggest that the race
model, which has not been studied extensively, can account for perceptual matching data at least as well as the diffusion
model. Furthermore, without the constraints on the parameters provided by the experimental conditions, the diffusion and the
race models are indistinguishable. This finding emphasizes the importance of fitting models across several conditions and
imposing logical psychological constraints on the parameters of models. 相似文献

Participants judged the affine equivalence of 2 simultaneously presented 4-point patterns. Performance level (d') varied between 1.5 and 2.7, depending on the information available for solving the correspondence problem (insufficient in Experiment 1a, superfluous in Experiment 1b, and minimal in Experiments 1c, 2a, 2b) and on the exposure time (unlimited in Experiments 1 and 2a and 500 ms in Experiment 2b), but it did not vary much with the complexity of the affine transformation (rotation and slant in Experiment 1 and same plus tilt in Experiment 2). Performance in Experiment 3 was lower with 3-point patterns than with 4-point patterns, whereas blocking the trials according to the affine transformation parameters had little effect. Determining affine shape equivalence with minimal-information displays is based on a fast assessment of qualitatively or quasi-invariant properties such as convexity/ concavity, parallelism, and collinearity. 相似文献

Sixteen right-handed participants (8 male and 8 female students) and 16 left-handed participants (8 male and 8 female students) were presented with cartoon faces expressing emotions ranging from extremely positive to extremely negative. A forced-choice paradigm was used in which the participants were asked to rate the faces as either positive or negative. Compared to men, women rated faces more positively, especially in response to right visual field presentations. Women rated neutral and mildly positive faces more positively in the right than in the left visual field, whereas men rated these faces consistently across visual fields. Handedness did not affect the ratings of emotion. The data suggest a positive emotional bias of the left hemisphere in women. 相似文献
