The hypothesis that memory is stored through a single stage of consolidation that results in a stable and lasting long-term memory has been challenged by the proposition that reactivation of a memory induces reconsolidation of the memory. The reconsolidation hypothesis is supported by evidence that, under some conditions, post-retrieval treatments affecting amygdala and hippocampus functioning impair subsequent retention performance. We now report that repeated retention testing attenuates the performance impairment induced by post-retrieval reversible inactivation of the amygdala and hippocampus of rats induced by tetrodotoxin. These findings challenge the reconsolidation hypothesis and suggest that the post-retrieval retention performance impairment is best explained as due to temporary retrieval failure. 相似文献

Prior studies have indicated that multiple knowledge structures, schema, associations, and cases, are involved in creative thought. Few studies, however, have examined how these different knowledge structures operate together in idea generation and creative problem-solving. Accordingly, in the present study 247 undergraduates were asked to generate ideas relevant to a social innovation problem and then provide a potential solution to the problem. A training manipulation was used to encourage application of schematic, associational, or case-based knowledge either alone or in combination. It was found that prompting use of a single knowledge structure, specifically schema or associational knowledge, resulted in the production of more high quality ideas. However, prompting use of multiple knowledge structures, specifically combining either schema or associations with cases, resulted in the production of higher quality and more original problem-solutions. The implications of these findings for understanding the role of different knowledge structures in creative thought are discussed. 相似文献

Implicit in much of the fatherhood discourse is the assumption that if fathers want to take an active role in their children's lives, they could and would do so. While research has highlighted the factors associated with fathers' involvement, very few, if any, of these studies have been guided by a theory that accounts for both fathers' involvement intentions and their ability to follow through on those intentions. The theory of planned behavior and its emphasis on attitudes, the beliefs of significant others, and whether one has control over engaging in behavior is a conceptual fit to respond to questions related to the complex nature of paternal involvement. Using data from the Fragile Families and Child Well‐being Study, the purpose of this study was to test the utility of the theory of planned behavior in predicting fathers' involvement intentions and reports of involvement. The results revealed that the theory of planned behavior can be useful in examining paternal involvement and should be used in future research to enhance the fatherhood literature. 相似文献

This study explored the relationship between illegitimate birth and cognitive development among 513 boys on probation. Prior research has shown that being part of a single-parent household leads to diminished verbal capacities and often puts a child in greater danger of abuse and neglect. Frequent abuse is thought to lead to the enhancement of visual and spatial skills relative to verbal skills through a process of “frozen watchfulness”. I hypothesized that illegitimate boys from one-parent homes would have greater verbal-performance discrepancy scores than would boys from other combinations of birth status and family structure. These boys had the lowest verbal IQ and highest performance IQ scores and, hence, the largest discrepancy. These boys also suffered the highest degree of abuse and neglect of all four birth status/family structure combinations studied. 相似文献

The main goal of this study was to measure longitudinally change in thought processes and reality testing of a prepsychotic adolescent undergoing psychotherapy. The Holt scoring system for measuring primary process from Rorschach responses was the main measuring instrument. Four Rorschachs were administered over a period of three years. The results of the latter were compared with the clinical ratings of two psychiatrists. While clinical change in response to treatment was slight, there did appear to be a shift from primary to more secondary forms of formal thought processes as determined by the Rorschach. 相似文献

Measures of oral reading fluency (ORF) are perhaps the most often used assessment to monitor student progress as part of a response to intervention (RTI) model. Rates of growth in research and aim lines in practice are used to characterize student growth; in either case, growth is generally defined as linear, increasing at a constant rate. Recent research suggests ORF growth follows a nonlinear trajectory, but limitations related to the datasets used in such studies, composed of only three testing occasions, curtails their ability to examine the true functional form of ORF growth. The purpose of this study was to model within-year ORF growth using up to eight testing occasions for 1448 students in Grades 1 to 8 to assess (a) the average growth trajectory for within-year ORF growth, (b) whether students vary significantly in within-year ORF growth, and (c) the extent to which findings are consistent across grades. Results demonstrated that for Grades 1 to 7, a quadratic growth model fit better than either linear or cubic growth models, and for Grade 8, there was no substantial, stable growth. Findings suggest that the expectation for linear growth currently used in practice may be unrealistic. 相似文献
