Longitudinal data from 84 head-injured children and adolescents, who were tested at three points in the first year postinjury, were analyzed to determine the best combination of demographic, injury-related, and behavioral factors predicting cognitive performance. Dependent variables were language, memory, visuomotor, and speeded performance factor scores obtained through confirmatory factor analyses of an extensive test battery. Multiple regression analyses indicated that injury severity and the existence of previous psychological, physical, or cognitive disorders were primary for predicting acute (1 month post-hospital discharge) performance for older subjects. For younger subjects, however, parental marital status was the most important correlate of acute cognitive performance. Those residing in homes with both parents fared better than children in one-parent families. At 6 months and 1 year postinjury, the older subjects who performed most poorly initially remained the most impaired. For younger children, acute cognitive standing was also an important predictor of later performance, but parental marital status remained a crucial influence on their longer-term recovery of cognitive skills. 相似文献

A number of software tools are available that do symbolic computation that can facilitate the theoretical analysis of a mathematical model. We made use of one these tools, Mathematica (Wolfram, 1988), to implement the global familiarity memory models of Gillund and Shiffrin (1984) and Murdock (1982, 1983). We describe our implementation, and illustrate the flexibility and efficiency of use that these tools allow. 相似文献

A critical evaluation of the semantic-episodic distinction 总被引:2,自引:0,他引:2

Tulving (1983, 1984) has recently claimed that a wide range of evidence supports the distinction between episodic and semantic memory systems. He has provided a list of features to describe the differences between the two systems and a set of experimental results to demonstrate the distinction. In this article, we present opposing evidence that invalidates many of the distinguishing features and contradicts interpretations of the supporting experiments. In addition, we argue that the question of whether there are two separate memory systems cannot be answered without a specific theory about the differences between the systems. 相似文献

Memory connections between thematically similar episodes 总被引:1,自引:0,他引:1

Recent theories about the representation of thematic information in memory propose that two episodes that share a theme are connected together through a thematic structure. We investigated the use of such cross-episode connections in comprehension and memory in six experiments. Experiments 1 and 2 used a priming technique; it was found that verification time for a test sentence from one story was speeded by an immediately preceding test sentence from a thematically similar story but only when subjects were given instructions to rate the similarities of the stories. In the remaining experiments, a single test sentence was presented immediately after a story was read, with timing controlled by presenting the story one word at a time. Response time for a test sentence from a previously read story was facilitated if the immediately preceding story was thematically similar, but only if the previously read story was extensively prestudied. We conclude that, during reading of an episode, thematic information may be encoded so as to lead to activation of similar episodes and formation of connections in memory between episodes, but such encoding is not automatic and depends on subjects' strategies and task difficulty. 相似文献

Induced motion (IM) was measured as a function of the temporal frequency of inducer oscillation. IM magnitude decreased as frequency increased above 5 Hz. Increasing the amplitude of inducer motion, and thereby its velocity, did not influence the temporal frequency dependence of IM. This suggests that it is the duration of inducer motion, rather than its velocity, that is the critical stimulus feature in studies that report decreased IM with higher frequencies of inducer oscillation. In a separate experiment, the optokinetic nystagmus elicited by the inducing stimulus in the absence of a fixation target displayed frequency-response characteristics similar to those of IM. This finding supports the hypothesis that IM magnitude is proportional to the voluntary effort required to suppress reflexive eye movements while maintaining stable fixation. 相似文献

This study investigated the relation between couples’ communication and marital satisfaction and the possible predictive influence of communication on the marital satisfaction among selected couples of Quezon City, Metro Manila, Philippines. The study was conducted among 82 married couples, and the results showed a significantly positive relationship between couples’ communication and marital satisfaction. Relational Communication Scale and Primary Communication Inventory were used to measure the couples’ communication, while Dyadic Adjustment Scale and Locke–Wallace Marital Adjustment Test were used to measure the marital satisfaction among the couples. A regression analysis of the data significantly showed that 90.4% of variance in marital satisfaction can be accounted for by couples’ communication. The results carry clear and meaningful implications for the role of couples’ communication in building and maintaining happy and satisfying marital relationship. This correlational and predictive study was undertaken to explore the need as well as the scope of a couples’ communication program for enhancing marital satisfaction. 相似文献

It is important to demonstrate replicable evidence of the effectiveness of counselling procedures. The study aimed to contribute to the currently limited evidence base examining the effectiveness of university student counselling in the UK. Information on therapeutic outcome [based on Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) scores] for 305 individuals attending a large UK university counselling service was analysed. Following counselling intervention: there was a statistically significant improvement in CORE-OM scores with 63% of individuals showing a reliable improvement and only 2% showing a reliable deterioration. Of those who began with a score in the clinical range, 49% showed a clinically significant change. These results provide additional evidence for the effectiveness of university counselling interventions. Future research should aim to build on this preliminary research using randomised controlled trial designs. 相似文献
