Daily food intake in rats was temporarily reduced by the introduction of an activity wheel and temporarily increased by the subsequent removal of the wheel. When this outcome is coupled with the positive relation between food deprivation and running—and food deprivation is seen as a loss of eating rather than as a physiological state—there is the suggestion that the total behavior output of the organism may be regulated as such. Specifically, when the rat is deprived of a behavior that recurrently comprises a large part of its total daily activity, an increase may occur in some other behavior. 相似文献

3 groups of university freshmen took the SAT-V before and after a course in Accelerated Reading. The mean post-test scores for 2 groups increased slightly less than 10 points, while the mean post-test score for the third group decreased significantly. It is concluded that for the type of students used in this study, a course emphasizing speed and accuracy of reading is not of value in increasing scores on the verbal part of the Scholastic Aptitude Test. 相似文献

An adaptation-level model for memory was tested by interpolating different weights between the standard and comparison weights. The results suggest that the model should be modified to account for the general tendency to use alternative categories of judgment with equal frequency. In terms of the modified model, memory for the standard shifts toward the value of the interfering stimulus, the magnitude of shift being proportional to the difference between the interfering stimulus and the value the memory would otherwise have had. 相似文献

The parent-child relationship plays an important role in Boszormenyi-Nagy's contextual therapy. This article presents the results of four interview studies of the opinions of parents and children about their ethical relationship.The children in these studies were five-to-seven-year-olds, 10-to-12 year olds and 15-year-olds. In one study only the mothers were interviewed, in the other three both parents participated. In all 73 children, 62 mothers, and 43 fathers were interviewed. The majority of parents and children agreed with most aspects of Nagy's theory about the parent-child relation, but there were some notable exceptions. Very few shared Nagy's ideas about entitlement. The age of the child had a clear effect on the opinions of the children on the dimensions of trust/reliability, loyalty and shifting of the balance with age of the child and on the opinions of the parents on the dimensions of childrens' rights, parents' rights, and balance of fairness. The sex of the interviewee had some effect: Mothers and fathers differ on the dimension of parents' rights and adolescent girls and boys differ on the dimensions of childrens' rights and parents' duties. 相似文献

The disambiguation of threat/neutral homophones was investigated in high- and low-trait anxiety subjects who had been exposed
to either a positive or a negative mood manipulation procedure. Subjects were required first to spell each auditorily presented
word and second, to generate and speak a sentence using the word. Difference indices were calculated for the spelling and
the sentence usage data, i.e. the number of threat minus neutral interpretations. Examination of these indices revealed that
subjects exposed to the negative mood manipulation procedure produced relatively more threat than neutral interpretations
(for both spelling and sentence usage) than did subjects exposed to the positive mood manipulation procedure. Multiple regression
analyses revealed that both the trait anxiety and mood manipulation variables contributed significantly to the prediction
of the difference index on the spelling task. In the analysis of the use of homophones in sentences, only the mood manipulation
variable contributed significantly to the prediction of the difference index on the sentence usage task. 相似文献
