Reading disabled and nondisabled children (13-14 years of age) were presented lists of 10 words each at different rates (one word per 1, 2, and 4 sec), and immediately after the last word of each list they recalled the words in any order. Recall of the first few words presented from each list (the primacy effect) was lower in reading-disabled than nondisabled children, and slower presentation rates increased the primacy effect in both groups. These findings suggest that reading-disabled children are not completely failing to use elaborative encoding but are using less effective elaborative encoding than nondisabled readers. With all presentation rates, recall of the last few words (the recency effect) was comparable in both groups, suggesting that older reading-disabled children encode and recognize the stimuli and that elaborative encoding is deficient in reading-disabled in spite of adequate stimulus encoding and recognition. 相似文献

Previous studies have found differences among children in their relative reliance on spelling-sound rules and word-specific associations in reading words. Children at one end of the continuum ("Phoenicians") rely heavily on spelling-sound rules; children at the other end ("Chinese") are more likely to use specific associations. This study found evidence for a Phoenician-Chinese continuum in spelling as well as in reading. Ability to spell nonsense word (e.g., "prunt") correlated more highly with ability to spell regular words (e.g., "grunt") than with ability to spell exception words (e.g., "front"). Children who were skilled at rules tended to overgeneralize them to exception words. In addition, a measure of rule use in spelling correlated with measures of rule use in reading. 相似文献

Independent groups of 10-,20-, and 30-day-old infants were subjected to a classical eyelid conditioning procedure involving either a 500- or a 1500-msec interstimulus interval (ISI). Ten days later, all received a second conditioning session. A reliable increase in conditioned responding was observed at all ages but only by infants receiving the 1500-msec ISI. Although age was not a significant factor in any conditioning measure except final performance level, which was greater for the oldest than for the youngest group, it did influence long-term retention. A reliable memory component was observed in the Session 2 performance of infants initially trained at 20 and 30 days but not at 10 days. These data demonstrate the importance of temporal parameters in the formation of conditioned associations very early in infancy and provide evidence for the long-term behavioral consequences of those associations. 相似文献

Storage and processing constraints on integrating story information in children and adults 总被引:1,自引:0,他引:1

In two experiments, this study examined the effects of integration complexity on the ability of child and adult listeners to integrate information from different sentences in a story. First and third graders and college adults were read stories containing incongruent event information and succeeding resolution information that explained the incongruency, and asked questions that probed incongruency recognition and resolution. Information storage complexity was manipulated by separating the event and resolution information and foregrounding or backgrounding the focal story characters. Processing complexity was manipulated by varying the inferential complexity of relating the resolution to the incongruent information, and the coreferential cues linking the event and resolution information. The results showed that increases in complexity adversely affected resolution integration, and more for the children than for the adults. The children's integration performance, in particular, was affected by theme discontinuity and coreferential complexity. 相似文献

The numerous mechanisms of behavior change in infant development are sometimes difficult to distinguish. Although it is agreed that elicitation and reinforcement both influence infant learning, the distinction between these two learning mechanisms was clarified in response to K. Bloom's (1984, Journal of Experimental Child Psychology, 38, 93-102) commentary. The theoretical and methodological assumptions of an functional analysis of infant behavior were made explicit in the context of the C. L. Poulson study (1983, Journal of Experimental Child Psychology, 36, 471-489). The rationale for the use of DRO schedules to control for elicitation effects of continuous reinforcement and the inadequacy of noncontingent schedules for this purpose were also discussed. 相似文献

The development of anticipatory hand orientation during infancy 总被引:1,自引:0,他引:1
The development of infants' prehensile adjustments regarding the orientation of objects was investigated. Five- and nine-month-olds (N = 16 per group) were presented with horizontally and vertically oriented dowels to determine at what point during the reach, hand orientation approximated that of the dowel. Nine-month-olds rotated their hands appropriately, early in the course of the reach, i.e., before tactual contact of the dowel, whereas five-month-olds did so mostly after tactual contact. Analyses of the effects of trials within the experimental session indicated that this age difference was not associated with practice or fatigue effects. The results are discussed in relation to the development of visual control of prehensile behavior. 相似文献

Subjects at three grade levels, third, sixth, and college (8, 11, and 20 years of age, respectively), were asked to identify briefly presented words accompanied by either words or letter strings in the same or opposite hemifield. Results indicated two sources of visual field interference, one relating to the presence of alphanumeric information elsewhere in the visual field and the second concerning the meaningfulness (lexical identity) of that information. The former showed a decrease in importance with age, and the latter an increase. Results were discussed in terms of the development of selective attention and hemispheric interaction. 相似文献
