"Network interference and number-fact retrieval: Evidence from children's alphaplication": Erratum.

Reports an error in "Network interference and number-fact retrieval: Evidence from children's alphaplication" by D. Jeffrey Graham and Jamie I. Campbell (Canadian Journal of Psychology Revue Canadienne de Psychologie, 1992[Mar], Vol 46[1], 65-91). Figure 1 was inadvertently omitted. Reprints of this article, available from the authors, will include this figure. (The following abstract of the original article appeared in record 1992-42555-001.) Investigated the origins of several phenomena of number-fact retrieval by asking 45 children (aged 8 yrs 2 mo to 10 yrs 7 mo) to memorize alphaplication facts (arithmetic-like memory items composed of letters instead of numbers). Ss' performance in the task showed paralleled aspects of simple arithmetic performance. There was a strong performance advantage for tie over nontie problems on both reaction time (RT) and errors. Specific errors frequently involved operand-related answers. Correct RTs and error rates across problems were closely linked. Correct answers to poorly learned problems tended to be the most common error responses. Performance was not as good for problems that were introduced later in the learning sequence. Results support the network-interference approach to number-fact retrieval of J. I. Campbell and D. J. Graham (see record 1986-16912-001).

基于嵌入式零树小波编码直方图图像检索

图像和视频应用的快速增长，使得根据图像和视频内容进行查询的技术变得越来越重要，人们提出了许多基于像素域或压缩域的图像检索技术，因为多媒体数据库通常具有相当大的数据量，所以基于像素域图像检索技术的计算复杂度相当大，因此，许多文献提出更快的基于压缩域的图像检索技术，本文提出一种改进的基于嵌入式零树小波编码直方图的图像检索技术，特征提取综合考虑图像的颜色，纹理，频率和空间信息，所有的特征可以在压缩过程中自动得到，图像检索的过程就是匹配待检索图像和来自数据库的侯选图像的索引，实验证明这种方法具有好的检索性能。     

When Do Visual and Verbal Memories Conflict? The Importance of Working-Memory Load and Retrieval.

Examinations of interference between verbal and visual materials in working memory have produced mixed results. If there is a central form of storage (e.g., the focus of attention; N. Cowan, 2001), then cross-domain interference should be obtained. The authors examined this question with a visual-array comparison task (S. J. Luck & E. K. Vogel, 1997) combined with various verbal memory load conditions. Interference between tasks occurred if there was explicit retrieval of the verbal load during maintenance of a visual array. The effect was localized in the maintenance period of the visual task and was not the result of articulation per se. Interference also occurred when especially large silent verbal and visual loads were held concurrently. These results suggest central storage along with code-specific passive storage.

The relationship between attentional blink and psychological refractory period.

This study examined the relationship between attentional blink (AB) and psychological refractory period (PRP) using a conventional AB procedure combined with a requirement of speeded responses to the second target (T2). Experiments 1 and 2 showed that, as with PRP, memory retrieval of targets is not a necessary condition for the occurrence of AB in terms of accuracy and that AB occurred in the speed data. Experiment 3 further indicated that the PRP-like speed data were not due to the first target serving as a warning signal that triggered preparation of responses to T2. Experiment 4 manipulated T2 stimulus intensity to be normal or low. Results showed an underadditive interaction between stimulus intensity and lag position in the speed data, whereas an overadditive interaction was found in the accuracy data, suggesting 2 sources of interference leading to AB: the single-channel bottleneck and resource-limited visual-processing capacity.
