This paper examines the roles of early experience and relative plasticity in the development of social behavior in animals and humans. It is concluded that (1) long-term effects of early experience variables can be found in the animal and human literature; (2) there are age differences in the relative susceptibility to environmental influences during development; and (3) the power of environmental events and the buffering ability of the organism are crucial variables affecting the outcome of organism-environment interactions. 相似文献

An extensive set of neuropsychological measures was administered to 60 Parkinson's disease patients and age-, sex-, and education-matched controls in order to investigate the nature and prevalence of the cognitive deficit in the disease. Parkinsonian patients performed significantly poorer on all measures with the exception of tests for apraxia and object recognition, and on a test of vocabulary knowledge. Discriminant analysis of the test data revealed that over 93% of patients are impaired relative to matched controls, but that assigning a prevalence rate for dementia in the disease may be difficult due to the continuous distribution of cognitive deficits. 相似文献

Two interpretations of the poor readers' deficit are examined. According to one interpretation, poor readers are primarily deficient in use of phonetic information, and, thus, their deficit is specific to reading or at least to use of language. A second interpretation is that good and poor readers differ in their ability or tendency to use stimulus attributes—that is, partial information for stimulus identity—and, thus, their deficit is not specific to reading. Three experiments provide evidence favoring the second interpretation. Good and poor readers perform differently in tests of memory—whether or not the stimulus items are coded phonetically—when information about stimulus identity is incomplete due to memory loss and the response measure is sensitive to partial-information use in guessing. Likewise, the two groups perform differently in a perceptual task when information for stimulus identity is partial, but they perform at similar levels when information is complete. 相似文献

Previous etiological models of child abuse are reviewed, with particular emphasis on the current social interactional analysis. It is argued that while this model accounts for the documented correlates of abuse, it fails to provide a plausible mechanism for explaining the rapid acceleration from low- to high-intensity punitive behavior characteristic of abusive episodes. Drawing from research on interpersonal aggression by Berkowitz, Zillmann, and other social psychologists, a model is developed in which an arousal-mediated respondent component is added to the current instrumentally based punitive processes. Implications of this improved analysis for treatment and prevention are considered. 相似文献

Coaches make a variety of complex decisions in American-rules college football, especially related to point-after-touchdown (PAT) conversions and, historically, kicker selection. However, little research has characterized the pattern of these choices and whether they are sensitive to environmental manipulations, such as increased effort to score. In the present study, the generalized matching law (GML)—a model that predicts a linear relation between log-transformed choices for two alternatives and the amount of reinforcement garnered from them—was applied to PAT-conversion (1 point vs. 2 point) and kicker (soccer-style vs. conventional-style) selection using archived data from the National Collegiate Athletic Association. Overall, PAT-conversion and kicker selection exhibited matching. Further, narrowing the goal-post width was associated with decreased preference for one-point (relative to two-point) PAT attempts and enhanced sensitivity to increases in points scored from one-point (relative to two-point) PAT attempts. This investigation provides support for the ecological validity of the GML and demonstrates that complex decisions in football conform to an orderly pattern that can be described using the GML. 相似文献
