In his bookMind and body(1873), Bain set out an account in which he related the processes of associative memory to the distribution of activity in neural groupings—or neural networks as they are now termed. In the course of this account, Bain anticipated certain aspects of connectionist ideas that are normally attributed to 20th-century authors—most notably Hebb (1949). In this paper we reproduce Bain's arguments relating neural activity to the workings of associative memory which include an early version of the principles enshrined in Hebb's neurophysiological postulate. Nonetheless, despite their prescience, these specific contributions to the connectionist case have been almost entirely ignored. Eventually, Bain came to doubt the practicality of his own arguments and, in so doing, he seems to have ensured that his ideas concerning neural groupings exerted little or no influence on the subsequent course of theorizing in this area. 相似文献

Abstract— Strack and Förster (1995) showed that, unlike remember responses, know responses in recognition memory were influenced by manipulating response bias. We describe and experiment that replicated theirs but additionally allowed subjects to report guesses. Only guess responses were influenced by this manipulation. Response bias had no effects on either know or remember responses. This outcome suggests that manipulating response bias influence know responses only when guessing is encouraged but not reported as such. More-over, though know responses reflected memory for the study events, guess responses did not. 相似文献

It is the contention of this article that Proverbs chs. 1–9 is a literary unity in which wisdom has the denotation of the parental household teaching. Teachings which have other contexts in other parts of the Old Testament have in Pr. 1–9 a parental teaching context. Besides denoting the parental teaching, personified speaking Wisdom has the personal features of a teacher. Both Wisdom's features and her message serve to reinforce the parental teaching. Personified Wisdom also denotes the teaching of the entire Book of Proverbs. Through the device of personified Wisdom, the wisdom of Solomon enshrined in the Book of Proverbs is re-located from the royal court to the individual Israelite household. This is evident in the literary design of the book. It also reflects the situation of the book's redaction in post-exilic Judaism. 相似文献

We conducted a functional assessment of problem behaviors of 2 students with developmental disabilities in their classroom environments. Results of the assessments showed that although there were more tantrums in demand than in no-demand conditions, the function of the behavior was to gain attention (positive reinforcement) rather than to avoid or escape demands (negative reinforcement); demand conditions apparently served a discriminative function for the availability of attention. Therefore, intervention was based on the positive reinforcement hypothesis, resulting in a substantial reduction of tantrums for both subjects. 相似文献

I am not a Crook: Effects of Denials on Perceptions of a Defendant's Guilt, Personality, and Motives
Two studies were conducted to explore the effects of a defendant's overinformative denials (i.e., denials not prompted by an accusation or specific request) in a courtroom trial. Subjects read the testimony of a defendant who either did or did not deny several negative propositions (Study I) or whose denials either were or were not in response to the prosecutor's questions (Study 2). The denials had little effect on subjects' beliefs regarding the denied propositions. However, the defendant who provided the overinformative denials was perceived as being less trustworthy, more nervous, more concerned with presenting a positive image, and more likely to believe that others believed the negative propositions. Subjects who read the testimony of this defendant also generated more negative and fewer positive thoughts, and they perceived the defendant as being more guilty. The results illustrate the importance of the conversational context for determining the pragmatic meaning of a speaker's remarks. 相似文献

Reports of community alienation and high ingroup identification in the police suggest that they are a particularly ethnocentric group. To empirically test this hypothesis, a sample of urban police officers was surveyed to ascertain their social identity pattern. Results indicated a high level of peer solidarity, community alienation differentiated on the basis of race and social class, and the perception that the source of alienation lies more with the community than with the officers themselves. A central finding was that those officers who identified most strongly with peers also tended to report lower levels of alienation from the community groups. This finding, in conjunction with unremarkable levels of authoritarianism and perceived stress in the sample, challenges the stereotype of the ethnocentric, authoritarian, and stressed out police officer. Results are placed within a novel framework for understanding the police solidarity phenomenon, and implications for police-community relations are discussed. 相似文献

Towards a Hierarchical Model of Self-concept for Hong Kong Chinese Adults with Physical Disabilities
This paper explores the basic facets and structure of the self-concepts of groups of 135 and 146 Hong Kong Chinese adults with and without physical disabilities, respectively. Comparison of responses to a 20-item scale indicated a very similar pattern of the importance the individuals in these groups attached to these areas of their lives. However, the non-disabled group did report higher satisfaction ratings on six of these areas and factor analysis of both the importance and satisfaction ratings showed a similar underlying factor structure for both groups. Content analysis of open-ended questions confirmed that both groups shared similar self-concept facets except that the subjects with physical disabilities most frequently reported the importance of “functional independence in daily living tasks”. It is proposed that this facet needs to be included in a self-concept instrument appropriate for subjects with physical disabilities. Models of self-concept were then suggested for each group. 相似文献

Stimulus-independent thoughts (SITs) are streams of thoughts and images unrelated to immediate sensory input. Four experiments examined the contribution of aspects of working memory to production of SITs. In Experiments 1 and 2, interventions that were targeted on, respectively, phonological and visuospatial components of working memory both interfered with production of SITs, but there was evidence that these tasks also made demands on central executive resources. Experiments 3 and 4 specifically examined the hypothesis that production of SITs and control of nonproceduralized tasks both depend on central executive resources, and so should show mutual interference. In Experiment 3, prior practice on pursuit rotor and memory tasks reduced the interference with SITs from concurrent task performance. In Experiment 4, randomness within a task involving random-number generation was less when SITs were being produced concurrently than it was when they were not. The results suggest that production of SITs depends on central executive resources. 相似文献

Abstract— Previous research has shown that split-brain (callosotomy) patients search through visual displays twice as fast as normal observers when items are divided evenly between visual hemifields, as though each disconnected hemisphere possessed its own attentional scanning system (Luck, Hillyard, Mangun, & Gazzaniga, 1989, 1994) Results from 3 split-brain patients in the present study indicate that the ability to limit search to a relevant subset of the visual display is lateralized to the left cerebral hemisphere. This ability to perform guided search was not shown in the right hemisphere, even when the search time in that hemisphere was superior to search time in the left Furthermore, guided search was observed for both hemifields in normal control observers. These findings suggest that, as with higher cognitive processes such as language, strategic visuospatial attentional processes are preferentially lateralized to the left cerebral hemisphere. The findings also imply that the callosum mediates guided search in the right hemisphere of normal subjects 相似文献
