A series of three experiments was run to test the hypothesis that when animals are exposed to a cue from prior training, the context in which cueing occurs becomes associated with the training memory. The first experiment demonstrates that when rats are trained to avoid in one context and then are tested in a different context performance is reduced. Experiments 2 and 3 demonstrate that this performance deficit can be alleviated by cueing the rats in the test context prior to testing. The data suggested that the improved performance does not seem to result from the association of the cueing context with a fear response. These results are discussed in relation to the context addition hypothesis. 相似文献

Two experiments were conducted to investigate context effects on the lexical decision process. In both experiments, observers classified letter strings as words or nonwords following the presentation of context in the form of an incomplete sentence. In Experiment 1, the predictability of congruous word stimuli and their frequency of occurrence in printed English were varied. These two factors had independent and additive effects on decision latencies. Stimulus quality, word frequency, and semantic congruity (i.e., congruous vs. incongruous) between the context and the stimulus were varied in Experiment 2. The effects of semantic congruity and word frequency on decision latencies combined additively, as did the effects of semantic congruity and stimulus quality. Two complementary mechanisms were proposed within the framework of a modified version of Becker’s verification model to account for the differential effects of single-word and sentence context priming on the lexical decision process. 相似文献

Juvenile crime is a serious problem for which no treatment approach has been found to be reliably effective. This outcome evaluation assessed during and posttreatment effectiveness of Teaching-Family group home treatment programs for juvenile offenders. The evaluation included the original Achievement Place program, which was the prototype for the development of the Teaching-Family treatment approach, 12 replications of Achievement Place, and 9 comparison group home programs. Primary dependent measures were retrieved from court and police files and included number of alleged offenses, percentage of youths involved in those alleged offenses, and percentage of youths institutionalized. Other dependent measures were subjective ratings of effectiveness obtained from the program consumers, including the group home residents. The results showed difference during treatment favoring the Teaching-Family programs on rate of alleged criminal offenses, percentage of youths involved in those offenses, and consumer ratings of the programs. The consumer ratings provided by the youths and their school teachers were found to be inversely and significantly correlated with the reduction of criminal offenses during treatment. There were no significant differences during treatment on measures of noncriminal offenses (e.g., truancy, runaway, and curfew violations). In the posttreatment year, none of the differences between the groups was significant on any of the outcome measures. The results are discussed in terms of measurement and design issues in the evaluation of delinquency treatment programs and in relation to the evaluation of Teaching-Family group homes by Richard Jones and his colleagues. 相似文献

A study was conducted to investigate the effects on students' spelling achievement of variations in teacher assessment procedures. Teachers measured student spelling performance at a constant level of task difficulty using different measurement frequencies and different rules to interpret the data. Each teacher wrote two consecutive 3-week goals for improved spelling performance for two sets of 100 spelling words and then measured student performance either daily or weekly by dictating randomly selected words from each 100-word list. Teachers were trained to apply either a predetermined set of decision rules or their own judgment to the data to decide if the spelling program they had implemented for the student was effective. Ineffective programs were changed or modified. Results indicated that daily measurement was significantly more effective than weekly measurement in increasing spelling achievement and that, under certain conditions, decision rules were more effective than teacher judgment in determining when to make program changes or modifications.This research was conducted pursuant to Contract 300-77-0491 between the Bureau of Education for the Handicapped (now called Special Education Programs) and the University of Minnesota Institute for Research on Learning Disabilities. 相似文献

Interactions between the youths and group home parents in 10 group homes were directly observed during a 2-hour session in each home. These observations were compared to questionnaire measures of the youths' self-reported delinquency while in the group home, and their evaluation of the group home program. The results indicated that over the 10 homes there was a strong inverse correlation between mean self-reported delinquency and the average amount of time youths spent taking to (r
s
=–.95)and in proximity to (r
s
=–.81)their group home parents. Talking to group home parents also showed a positive correlation with the youths' evaluation of their group home program. Similar trends were found when the correlations were computed over individual youths, although the magnitudes were reduced. These data may have implications for our understanding of the relationship between parenting behaviors and delinquency, as well as for the improvement of group-home treatment programs.This research was supported by Grant MH20030 and by a postdoctoral research fellowship (Grant MH15200, awarded to the first author) from the National Institute of Mental Health (Center for Studies in Crime and Delinquency). These grants were made to the Bureau of Child Research and the Department of Human Development, University of Kansas. The authors wish to thank Susan Whitely for her statistical consultation, and Jay Atwater, Carol Cramer, and Lynette Forbes for their help in the data analysis. Appreciation is also extended to the many teaching-parents whose cooperation made the research possible. 相似文献

The present study reassesses trends in motivation to manage among college business students (N = 216). Motivation to manage scores are compared with J. B. Miner's (Personnel Psychology, 1974, 27, 605–613) results for three periods since the early 1960s, across two types of universities—public and private, and between males and females. Results indicate that the downward trend in motivation to manage scores appears to be reversing; business students at the private university scored higher on motivation to manage than those at the public university, and males scored higher than females. Implications for vocational research are discussed. 相似文献

The influence of prosodic structure on the resolution of temporary syntactic closure ambiguities 总被引:2,自引:0,他引:2

This paper investigates the influence of prosodic structure on the process of sentence comprehension, with a specific focus on the relative contributions of syntactic and prosodic information to the resolution of temporary syntactic closure ambiguities. We argue that prosodic structure provides an initial memory representation for spoken sentences, and that information from this prosodic representation is available to inform syntactic parsing decisions. This view makes three predictions for the processing of temporary syntactic ambiguity: 1. When prosodic and syntactic boundaries coincide, syntactic processing should be facilitated. 2. When prosodic boundaries are placed at misleading points in syntactic structure, syntactic processing should show interference effects. 3. The processing difficulties that have been reliably demonstrated in reading experiments for syntactically complex sentences should disappear when those sentences are presented with a felicitous prosodic structure in listening experiments. These predictions were confirmed by series of experiments measuring end-of-sentence comprehension time and cross-modal naming time for sentences with temporary syntactic closure ambiguities. Sentences with coinciding or conflicting prosodic and syntactic boundaries were compared to a prosodic baseline condition.This research was supported in part by NIMH grant R29 MH51768 to the first author and NIMH grant T32 MH19729 to the Northeastern University Psychology Department. 相似文献

A prevalent theory regarding the deterioration of semantic memory in Alzheimer's disease is that it is a bottom-up process. If this is true, performance on tests of attribute knowledge should decline more rapidly than performance on tests of categorical knowledge as dementia severity increases. In the present study, a convincing pattern of findings to either support or reject the theory failed to emerge. This raised questions regarding the ability to separate attribute and categorical knowledge, and whether one can be tested without influence of the other. Questions also were raised regarding the additional cognitive processes needed to complete tasks of semantic memory. 相似文献
