The coefficients of internal consistency and retest reliability had been rarely investigated within the methodology of dream content analysis. Analyzing a dream series of elderly, healthy persons obtained from weekly telephone interviews, the internal consistency of a series of 20 dreams and retests after 4 or 22 weeks, respectively, had been computed. The findings indicate that dream recall and dream length are quite stable, but dream characteristics such as bizarreness and emotional tone underlie large intraindividual fluctuations. In order to obtain reliable measures for these variables which will be important for correlational studies, including waking-life trait measures, one has to obtain as many dreams as possible (about 20) in a very short time period. Further research is needed to extend the present findings to diary dreams and laboratory dreams. 相似文献

ABSTRACTPrevious studies reported a memory facilitation effect in which increased attention to one task facilitates the memory performance on another. Here we examined the characteristics of this “attentional boost effect” (ABE), and demonstrated how attention level during memory encoding influences the ABE strength by changing the occurring frequency of the attention-engaging target signal relative to the non-attention-engaging distractor signal (Experiment 1), and the physical salience of colour of the target signal (Experiment 2). The results indicated stronger ABE in conditions with a low ratio of target signal trials and with a salient target signal. Experiment 3 examined the role of spatial attention, which sought to measure how the distance between the target signal and the to-be-encoded item would influence the ABE strength. The results showed that the ABE strength was not influenced by the distance between the two. Overall, these findings suggest ABE may be mainly based on temporal attention. 相似文献
