In this study we investigated the putative role of cognitive dysfunction, diagnosis (schizoaffective versus schizophrenia disorder), and alcoholism as risk factors for suicidal behavior among individuals with DSM-TV schizophrenia or schizoaffective disorders. Subjects received cognitive tests and medical records were reviewed for evidence of a history of suicide attempts or suicidal ideation. Discriminant analysis was used to identify cognitive test performance measures that distinguished those with versus those without suicidal behavior. None of the cognitive measures discriminated between the two groups. The rates of suicidal behavior (suicidal ideation and suicide attempts) did not differ between participants with versus those without comorbid alcohol use. An association was found between suicidal behavior and the diagnosis of schizoaffective disorder. It was concluded that the history of prominent mood syndromes characteristic of schizoaffective disorder contributes to increased risk of suicidal behaviors. Cognitive dysfunction and/or alcoholism did not contribute additionally to risk in this study. 相似文献

The purpose of this article is to develop a preliminary comprehensive model of antisocial development based on dynamic systems principles. The model is built on the foundations of behavioral research on coercion theory. First, the authors focus on the principles of multistability, feedback, and nonlinear causality to reconceptualize real-time parent-child and peer processes. Second, they model the mechanisms by which these real-time processes give rise to negative developmental outcomes, which in turn feed back to determine real-time interactions. Third, they examine mechanisms of change and stability in early- and late-onset antisocial trajectories. Finally, novel clinical designs and predictions are introduced. The authors highlight new predictions and present studies that have tested aspects of the model 相似文献

Thirty-two undergraduates inhaled odors while outlining episodes, set in 8 living rooms, involving either themselves or the actual inhabitants. They rated odors, rooms, and episodes on 7-point scales and were tested for odor recognition. Episodes were content analyzed, and the frequency of categories was assessed. Separate factor analyses determined relationships between rating scales and content analysis categories. Regression analysis showed greater odor recognition when participants judged the odor to fit the imagined episode but less recognition when an unpleasant odor was incongruously paired with a warm episode. Odor recognition also was greater when the narrative outlines described familiar characters figuring out the scenes. Results supported the congruity hypothesis, whereby odors become markers for meaningful scenes with which they fit. 相似文献

The current two-sample investigation, which incorporated Conservation of Resources (COR) and Person-Environment (P-E) fit theories, investigated the interaction effects of felt accountability × P-E fit on the work outcomes of job satisfaction, organizational commitment, depressed mood, and work intensity. Consistent with the conceptual underpinnings of felt accountability as either a threat or opportunity, satisfaction, work intensity, and organizational commitment increased in settings possessing both heightened answerability and high levels of P-E fit. Further, individuals reported a reduction in depressed mood when heightened accountability was coupled with high P-E fit perceptions. These findings were consistent across samples providing evidence of generalizability. Implications, strengths and limitations, and directions for future research are discussed. 相似文献

Working memory was designed to explain four benchmark memory effects: the word length effect, the irrelevant speech effect, the acoustic confusion effect, and the concurrent articulation effect. However, almost all research thus far has used tests that emphasize forward recall. In four experiments, we examine whether
each effect is observable when the items are recalled in reverse order. Subjects did not know which recall direction would
be required until the time of test, ensuring that encoding processes would be identical for both recall directions. Contrary
to predictions of both the primacy model and the feature model, the benchmark memory effect was either absent or greatly attenuated
with backward recall, despite being present with forward recall. Direction of recall had no effect on the more difficult conditions
(e.g., long words, similar-sounding items, items presented with irrelevant speech, and items studied with concurrent articulation).
Several factors not considered by the primacy and feature models are noted, and a possible explanation within the framework
of the SIMPLE model is briefly presented. 相似文献

Cases involving certain kinds of manipulation seem to challenge compatibilism about responsibility-grounding free will. To
deal with such cases many compatibilists give what has become known as a ‘soft line’ reply. In this paper I present a challenge
to the soft line reply. I argue that any relevant case involving manipulation—and to which a compatibilist might wish to give
a soft line reply—can be transformed into one supporting a degree of moral responsibility through the addition of libertarian
elements (such as alternative possibilities of a kind unavailable under determinism and executive control of the sort commonly
associated with agent-causation). From a compatibilist’s perspective the subtraction of libertarian elements should make no
difference to any assessment of the agent’s responsibility. The compatibilist should therefore judge the agent morally responsible
after the removal of the libertarian elements. Yet removal of the libertarian elements returns the case to its original form
and thus what started out as a soft line has now collapsed into a hard line reply. Various ways of resisting my argument are
considered, but each is shown to carry important burdens. 相似文献

In immediate serial recall short words are better recalled than long words. The word length effect has become pivotal in the development of short-term memory models. The current research tests one explanation of the word length effect; that it is related to proactive interference (PI). We report two experiments in which the relationship is directly tested. In the first experiment we show that word length effects can be observed over the first few trials in an experiment and that the effect shows itself primarily in the number of omissions made. In the second experiment we simultaneously test for PI and word length effects. Strong word length effects were present but there was little evidence for PI influencing either overall levels of recall or the word length effect. In short, no empirical support was found for PI as an explanation of the word length effect. 相似文献

Some current models of working memory argue that a passive short-term store is not involved in more dynamic working memory tasks. Other models argue that standard short-term memory and working memory tasks rely on common storage facilities. We examine these issues by exploring two signature effects of passive short-term storage in simple span, complex span, and Brown-Peterson tasks. The finding that all three tasks show word length and phonological similarity effects suggests that common processes or storage mechanisms are involved in all tasks. The implications for models of working memory are discussed. 相似文献
