The use of spelling-sound information in both reading and spelling was evaluated by having children read and spell nonwords and five types of words that differed in terms of their regularity for reading and spelling. The subjects were grade 3 children who had been psychometrically defined as good readers and good spellers (“good”), good readers and poor spellers (“mixed”), or poor readers and poor spellers (“poor”). Results indicated that all children attempted to use spelling-sound correspondences in both reading and spelling, although children in both the mixed and the poor groups had weaker knowledge of these correspondences and were less systematic in their use of them. Furthermore, even though the children in the mixed group had been matched with children in the good group on reading comprehension, the number and type of errors made by the mixed subjects on both the reading and spelling tasks were more similar to those of the poor subjects than to those of the good subjects. 相似文献

Four experiments examined the control of observing responses by information feedback during visual discrimination learning. Second-grade children participated in Experiment 1; kindergarten, second-, and fifth-grade children were subjects in Experiments 2 and 3, and grade 5 and adult subjects were tested in Experiment 4. In order to view the stimuli, subjects in Experiments 1, 2, and 3 activated lights in viewing boxes; in Experiment 4, stimulus fixations were measured using a corneal reflection technique. Fifth graders and adults observed the discriminative stimuli for longer times on trials following negative feedback than on trials following positive feedback; in contrast, kindergartener's observing was not affected by type of feedback. Second graders showed smaller and less reliable reactions to type of feedback than did older subjects. These results support the view that visual observing is controlled by cognitive processes associated with hypothesis testing. 相似文献

Attitude and personality characteristics of 29 stutterers (19 male, 10 female) aged 52–82 yr were assessed using five questionnaires. Results indicate that, while the older stutterers score approximately the same as young adult stutterers on scales assessing approach and performance behaviors, the large majority of older stutterers perceive their stuttering as less handicapping than when they were young adults. Self-perceived personality characteristics of the older stutterers were similar to a group of older nonstutterers. While a few of the subjects had experienced some degree of success as a result of treatment later in life, the majority of the subjects did not currently desire treatment. 相似文献

Two experiments are described in which subjects rated as high or low in achievement motivation were exposed to uncontrollable outcomes on a cognitive task. Effects on subsequent performance on a different cognitive task were shown to depend on level of achievement motivation, on whether the uncontrollable outcomes were predictable or unpredictable, and on whether the uncontrollable outcomes were positive or negative. These findings have important theoretical implications which are discussed. 相似文献

Invariance of matching is shown to be necessary and sufficient for the existence of sensitivity functions that are unique up to multiplication by arbitrary positive real numbers. Examples from auditory and visual psychophysics are discussed. 相似文献

Semantic and visual memory codes in learning disabled readers 总被引:2,自引:0,他引:2
H L Swanson 《Journal of experimental child psychology》1984,37(1):124-140
Two experiments investigated whether learning disabled readers' impaired recall is due to multiple coding deficiencies. In Experiment 1, learning disabled and skilled readers viewed nonsense pictures without names or with either relevant or irrelevant names with respect to the distinctive characteristics of the picture. Both types of names improved recall of nondisabled readers, while learning disabled readers exhibited better recall for unnamed pictures. No significant difference in recall was found between name training (relevant, irrelevant) conditions within reading groups. In Experiment 2, both reading groups participated in recall training for complex visual forms labeled with unrelated words, hierarchically related words, or without labels. A subsequent reproduction transfer task showed a facilitation in performance in skilled readers due to labeling, with learning disabled readers exhibiting better reproduction for unnamed pictures. Measures of output organization (clustering) indicated that recall is related to the development of superordinate categories. The results suggest that learning disabled children's reading difficulties are due to an inability to activate a semantic representation that interconnects visual and verbal codes. 相似文献

This article attempts to distinguish between science and technology, on the one hand, and engineering, on the other, offering
a brief introduction to engineering values and engineering ethics. The method is (roughly) a philosophical examination of
history. Engineering turns out to be a relatively recent enterprise, barely three hundred years old, to have distinctive commitments
both technical and moral, and to have changed a good deal both technically and morally during that period. What motivates
the paper is the belief that a too-easy equation of engineering with technology tends to obscure the special contribution
of engineers to technology and to their own professional standards and so, to obscure as well both the origin and content
of engineering ethics. 相似文献

As a multivariate model of the number of events, Rasch's multiplicative Poisson model is extended such that the parameters
for individuals in the prior gamma distribution have continuous covariates. The parameters for individuals are integrated
out and the hyperparameters in the prior distribution are estimated by a numerical method separately from difficulty parameters
that are treated as fixed parameters or random variables. In addition, a method is presented for estimating parameters in
Rasch's model with missing values.
