Eye movements and eye fixations were recorded to study the integration of letter/word information across interword fixations in reading. Two hypotheses were examined. One hypothesis posits that readers obtain effective information from the beginning two or three letters of a parafoveal word. This information facilitates the recognition of the word when it is being fixated. The alternative posits that effective information is obtained from the complete parafoveal word. The results of the present study showed faster reading rates when parafoveal previews comprised complete words than when they comprised beginning letters alone. Furthermore, the usability of parafoveally available partial word information from beginning and ending letters was not affected by small variations in retinal eccentricity. Both findings were taken as evidence that readers gain useful information from all letters of the parafoveally available word and that whole word information, rather than specific letter information, is integrated across interword fixations in reading. 相似文献

This study examined the relationship between drug use and delinquent behavior among 348 high school males (154 whites, 172 Mexican-Americans, and 22 blacks) and 89 adjudicated delinquent males confined to a maximum-security facility for violent and repeat offenders (37 whites, 25 Mexican-Americans, and 27 blacks). Data were collected in the spring of 1986 using self-administered questionnaires. Analyses were performed separately for each racial subgroup. Simple correlations revealed that self-reported alcohol, tobacco, marijuana, and other illegal drug use were all significantly related to both minor and violent delinquency for all three racial groups. Multiple regression analysis revealed that the use of these substances accounted for 40% to 47% of the variance in minor delinquency and for 59% of the variance in violent delinquency among blacks, 53% of the variance in violent delinquency among Mexican-Americans, and 34% of the variance in violent delinquency among whites. The best predictors of violent delinquency were the frequent use of illegal drugs other than marijuana and use of tobacco, in that order, among Mexican-Americans; the frequent use of other illegal drugs, marijuana, and tobacco, in that order, for whites; and the frequent use of illegal drugs, followed by marijuana, for blacks. 相似文献

Competition is an important force behind evolution in present-day ecological conditions, its intensity varying according to the organisms' expectations vis-à-vis resources available. On the other hand, the role of mutation in the evolutionary process can hardly be underestimated: Leading to the change of the preconsciously functioning archetype, mutation makes it impossible for the ego to realize its image. This is a consequence of the clash between the mutated, preconsciously functioning archetype and the system of ethical and moral norms functioning in the collective superego of a given population group. The type of mutation that results from the accelerated pace of evolution can be viewed as a continuity in the development of an organism's behavior. The preconsciously functioning archetype, resulting from these mutations, contains impulses and predispositions that differ markedly from the impulses and predispositions functioning in the genetically determined "pattern of behavior." In a situation where anxiety results from the inhibition of impulses and dispositions, hostility reactions are likely to occur. In its turn, reactive hostility can induce anxiety, thus creating a reaction cycle. Underlying this mechanism is the mutated, preconsciously functioning archetype, which itself is a result of the development of civilization in our contemporary world. 相似文献

Grünbaum's approach to psychoanalysis suffers from several difficulties. It imposes a standard of logical reductionism and methodological purity that not only violates the nature of psychoanalytic knowledge, but imposes an invalid standard of verification and scientific confirmation. It utilizes a brand of dichotomous reasoning that forces psychoanalytic propositions into artificial positions that do not reflect the actuality of analytic practice. It imposes a standard of verification that is impossible for psychoanalysis, along with all forms of psychological knowledge, to reach. It visualizes psychoanalysis as encompassing only one form of knowledge of human psychic life, forcing it into a model that eliminates other aspects of the psychoanalytic process, so that psychoanalysis is subjected to criticism only on one dimension among several--a kind of psychoanalytic straw man. The psychoanalysis that is so impaled often is difficult for the psychoanalytic practitioner to recognize. To the extent that Grünbaum's skillful and highly informed criticism of the philosophical bases of psychoanalysis encounters these difficulties, the value of his argument falls short of providing a useful basis for advancing psychoanalytic knowledge and particularly for promoting the quest for pertinent standards of validation within psychoanalysis. 相似文献

Our research program focuses on thought systems consisting of a core event that might befall a person and other topics evoked in free associating on this event, mostly its salient antecedents and consequences. We theorize that the pattern of salient antecedents and consequences evoked by the core event are related to its judged desirability and likelihood by several adaptive principles, such that when a change is directly induced in one part of the belief system it produces predictable remote adjustments in other parts. In a first experiment we manipulated the core event's judged desirability or likelihood and tested for predicted remote effects on the salience of antecedents and consequences. A second experiment conversely manipulated the salience of antecedents or consequences and tested for predicted remote effects on the core event's judged desirability and likelihood. 相似文献

In this paper, we study the ability of a non-fluent aphasic patient, BN, to comprehend morphologically complex words when they appear in utterance contexts. We first establish that he is insensitive to the contextual appropriateness of both derived and inflected words. In a further experiment we show that he has no difficulty processing the stems of complex words and conclude that his problem is with the bound morphemes themselves. We then ask whether this problem is due to his inability to access either the phonological form of a morphologically complex word or its semantic and/or syntactic content. We find that only the access of semantic and syntactic content is impaired. We conclude from these six studies that: (a) BN presents a counter-example to the claim that non-fluent patients have particular difficulty with those aspects of morphology which have a syntactic function; (b) BN processes both derived and inflected words by mapping the sensory input onto the entire full-form of a complex word, but the semantic and syntactic content of the stem alone is accessed and integrated into the context. The semantic and syntactic implications of the suffix are never evaluated. This implies separate representation of the stems and suffixes of some types of morphologically complex words. 相似文献

We conducted three experiments to investigate the mental images associated with idiomatic phrases in English. Our hypothesis was that people should have strong conventional images for many idioms and that the regularity in people's knowledge of their images for idioms is due to the conceptual metaphors motivating the figurative meanings of idioms. In the first study, subjects were asked to form and describe their mental images for different idiomatic expressions. Subjects were then asked a series of detailed questions about their images regarding the causes and effects of different events within their images. We found high consistency in subjects' images of idioms with similar figurative meanings despite differences in their surface forms (e.g., spill the beans and let the cat out of the bag). Subjects' responses to detailed questions about their images also showed a high degree of similarity in their answers. Further examination of subjects' imagery protocols supports the idea that the conventional images and knowledge associated with idioms are constrained by the conceptual metaphors (e.g., the MIND IS A CONTAINER and IDEAS ARE ENTITIES) which motivate the figurative meanings of idioms. The results of two control studies showed that the conventional images associated with idioms are not solely based on their figurative meanings (Experiment 2) and that the images associated with literal phrases (e.g., spill the peas) were quite varied and unlikely to be constrained by conceptual metaphor (Experiment 3). These findings support the view that idioms are not "dead" metaphors with their meanings being arbitrarily determined. Rather, the meanings of many idioms are motivated by speakers' tacit knowledge of the conceptual metaphors underlying the meanings of these figurative phrases. 相似文献
