An on-line computerized management information system has been developed at the Salt Lake City VA Hospital and is currently being implemented at Salt Lake Community Mental Health Center. An introduction to this system, including systems design and procedures for development, are presented. The advantages of on-line technology as compared to batch processing technology are also discussed. 相似文献

The purpose of the present study was to examine the role of interest-present job congruency as a moderator of the relationship between job tenure and job satisfaction and mental health. In a sample of 54 middle managers, significant moderator effects were found for the mental health indices of self-esteem, life-satisfaction, and overall mental health and for satisfaction with supervision. As expected, these indices correlated positively with job tenure for high congruency individuals. For low congruency individuals, the relationships were expected to be negative. However, the obtained correlations did not differ significantly from zero. 相似文献

An overt rehearsal procedure was used to study the relationship between children's rehearsal strategies and their memory performance under different conditions of test expectation. Previous work has shown that developmental differences in rehearsal content affect recall performance. This study was designed to address the question of why active rehearsal content results in superior recall performance. The equivalence of recognition-memory performance for third- (age 9) and sixthgraders (age 12) suggests that developmental differences in recall are due to the effects of rehearsal content on item retrieval from permanent memory. In addition, the data indicate that third- and sixth-graders can differentiate between expected recall and recognition tests and, with the exception of the sixth-grade boys, use this information to modify their rehearsal content. These differences in rehearsal content, as a function of the type of test expected, corresponded to changes in recall performance. 相似文献

This experiment investigated speed of processing the grammaticality of phrases consisting of the adjective “one” or “two” followed by a singular or plural noun. The subject’s task was to press one of two keys, depending upon whether the phrase was grammatically correct or incorrect. There were eight types of phrases, formed by the factorial combinations of singular or plural adjectives, singular or plural nouns, and high or low noun imageD’. These served as within-subjects variables. Between-subjects variables were the factorial combinations of sex of subject, duration of stimulus phrase (.2 or 2.5 sec), and hand assigned to the correct-grammar key. A fourth between-subjects variable was whether or not the subject reported using an artificial phrase-scanning strategy to determine grammaticality. Correct grammar, singular noun form, high noun imagery, and reported use of the strategy all produced highly significant reductions in reaction times. Only 1% of the interactions were significant. A multistage serial processing model that could be based upon Sternberg’s additive factor paradigm or even Donders’ subtraction method was found to be highly successful in describing the results. 相似文献

The results of a recent study (Liberman, Shankweiler, Liberman, Fowler, & Fischer, 1977) suggest that good beginning readers are more affected than poor readers by the phonetic characteristics of visually presented items in a recall task. The good readers made significantly more recall errors on strings of letters with rhyming letter names than on nonrhyming sequences; in contrast, the poor readers made roughly equal numbers of errors on the rhyming and nonrhyming letter strings. The purpose of the present study was to determine whether the interaction between reading ability and phonetic similarity is solely determined by different rehearsal strategies of the two groups. Accordingly, good and poor readers were tested on rhyming and nonrhyming words using a recognition memory paradigm that minimized the opportunity for rehearsal. Performance of the good readers was more affected by phonetic similarity than that of the poor readers, in agreement with the earlier study. The present findings support the hypothesis that good and poor readers do differ in their ability to access a phonetic representation. 相似文献

If one considers stuttering to be one possible outcome of a developmental and learning process, it is possible to conclude, a priori, that both environmental variation and genetic variation are likely to be involved in determining those who ever stutter and those who never stutter. Proof exists of the importance of nongenetic (environmental) variation in the etiology of stuttering; no conclusive proof exists of the involvement of genetic variation. The available evidence on the familial concentration of stuttering is compatible with hypotheses that incorporate a major genetic component. According to these hypotheses, the familiality is due to genetic transmission, and the interaction of genetic predisposition with environmental factors is affected by the individual's sex. No conclusion is yet possible on the specific type of genetic transmission. 相似文献

Aid programs can be used as an antidote to social conflict. Under certain conditions, however, they may create hostility. In this experiment subjects representing six hypothetical countries (1) either received or did not receive material aid from a seventh nation and (2) had a high or low level of material need. Attraction for the aid-giver decreased markedly when aid was denied, but increased very little when it was granted. When subjects were high in material needs, the denial of aid produced maximal antagonism. However, when aid was received, high need did not enhance attraction to the donor. The implications of these findings for an exchange theory of attraction and for aid giving are discussed. 相似文献
