Previous research suggests a developmental lag between producing a strategy of selective attention and benefiting from it. This aspect of the transitional period during strategy acquisition was investigated in the present study by comparing recall following child-produced (Session 1) and experimenter-produced (Session 2) strategies. The 114 7-9-year-olds were told to remember a subset of 6 items (either animals or household) located beneath 2 rows of doors. Session 1 assessed each child's spontaneous strategy (pattern of opening doors) over 6 trials. Session 2 included 7 different trial types, during which the experimenter opened the doors, thereby equating the strategies for children of all ages. The results revealed gradual changes in children's ability both to produce and to benefit from a selective strategy. Whereas younger children performed differently on trial types during which only the 6 relevant versus all 12 items were shown, older children recalled a similar number of items for all trial types, regardless of the number or pattern of door openings provided. Adult-produced selectivity eliminated recall differences among the grades and suggested that strategy production is effortful for younger children and therefore may prevent their benefiting from the strategy. 相似文献
Three groups of students--19 hard of hearing, 20 deaf, and a control group of 36 typically developing hearing readers--were compared on their ability to process written words at the lexical level and on their comprehension of words within the structure of a sentence. Findings generally suggested that severe prelingual hearing loss does not prevent the development of word processing strategies adequate for efficient processing of written words at the lexical level, although such hearing loss seems to put individuals at risk of failure in internalizing syntactic knowledge crucial for proper processing of words at the sentence level. Evidence further indicated that neither the amount of functional hearing (deaf vs. hard of hearing), the hearing status of their parents (hearing impaired vs. hearing), nor the use of sign language as a primary communication mode was a direct cause in this regard. 相似文献
Treatment provisions planned and executed were studied in a follow-up of 14 abused or neglected children three years after discharge from the Children's Department of Ullevaal Hospital. A majority of the families were shown to have received either no help or inappropriate help. Half of the children were evaluated as being so emotionally impaired that serious future adjustment problems could be anticipated. Inappropriate treatment related to lack of understanding, workers' own feelings and normative standards. Overidentification with parents and a general belief in their ability to develop caring skills were observed as was the tendency to overlook or minimize the child's experiences and the risk to which he was exposed. Anxiety, insecurity and lack of skill in establishing appropriate relationships prevented workers obtaining adequate bases for evaluation and for effectuation of treatment. Workers' professional situations were unfavorable in specified ways. Appropriate treatment was based on differentiated psychosocial evaluation, a high involvement level by the worker and continuity. The professional situation was also favorable. Workers combined traditional therapeutic approaches with conscious use of professional authority. They intervened actively for protective purposes but were empathetic with both child and parents. 相似文献
The objective of this experiment was to compare the impact of a cooperative learning format with a traditional lecture-oriented format in the teaching of introductory biology. Differences were found in favor of the cooperative learning format in measures of student satisfaction, the ability to find information on one's own, the acquisition of factual knowledge, and the ability to work with others. The results of this study affirm the viability of using a cooperative learning approach over a traditional lecture format.Judith E.

The present article focuses on connections between part-time special education and the good results of Finnish students in PISA studies. After a brief summary of the comprehensive school system and special education in Finland, PISA results are analysed. The analysis shows that the relative amount of special education targeted at language problems is highest in Finland among those countries from which comparative statistics are available. The writers argue that this preventive language-oriented part-time special education is an important factor behind the good PISA results. 相似文献
The attention to students’ noncognitive attributes has recently flourished within academic research and public discourse. This paper adds to the literature by examining the interrelationships among several key noncognitive attributes as well as exploring direct and indirect relationships between noncognitive attributes and second-year retention. Within a multi-institutional sample of 10,622 students, academic self-efficacy, academic grit, self-discipline, and time management all load onto a single noncognitive factor with strong inter-item correlations and internal reliability. Moreover, structural equation modeling analyses indicate a sizable and positive indirect effect of noncognitive attributes on college retention, which is mediated by social adjustment, institutional commitment, and college grade point average.
A recent study found that avoidance extinction is equally facilitated by response prevention (blocking) whether the latter involves CS-alone or CS-shock presentations. An experiment was performed to determine whether this result was due to the use of a lengthy shock (5 sec) during response prevention. Five groups of rats were extinguished: (1) without prior blocking, (2) after blocking with CS only, (3) after blocking with a lengthy (5 sec) CS-contingent shock, (4) after blocking with a brief (.5 sec) CS-contingent shock, or (5) after blocking with a brief (.5 sec) shock only. The group blocked with the brief CS-contingent shock was substantially more resistant to extinction than the other four groups. The unblocked group and the group blocked with brief shock only required more trials to extinguish than the groups blocked with CS only or with lengthy CS-contingent shock, but did not differ from each other. The groups blocked with CS only or with lengthy CS-contingent shock also failed to differ from one another. The data support a significant role for Pavlovian conditioning processes in the effect of response prevention upon avoidance extinction. 相似文献
Two experiments indicated that two approaches to serial learning are too extreme—the classical view that it consists only of interitem associations and various recent views that it involves no interitem associations. The novel assumption introduced here was that phrasing cues, normally conceptualized as merely segregating long series into smaller units or chunks, may also enter into associations with items, thereby reducing interitem interference and facilitating serial learning. It was found that one item could become a signal for another item, an interitem association, or be overshadowed by a phrasing cue, such as a brightness and temporal cue, also signaling that item. The items were .045-g pellets. Rats traversed a runway for items arranged in ordered series, 14-7-3-1-0 pellets (Experiment 1) or 10-2-0-10 (Experiment 2). Complete tracking of, for example, the 10-2-0-10 series would consist of fastest running to 10 pellets and slowest running to 0 pellets. In both investigations, the interitem association overshadowed was that between 0 pellets and the subsequent rewarded item, 0 → 14 (Experiment 1) or 0 → 10 (Experiment 2). Either repetitions of the 14-7-3-1-0 subpattern (Experiment 1) or merely the terminal 10-pellet item (Experiment 2) were phrased, both methods producing identical results. Overshadowing the 0-pellet item produced superior serial learning, more rapid extinction, and, in Experiment 1, considerable elevation of responding when the brightness phrasing cue was introduced in extinction, an effect said to be conceptually identical to spontaneous recovery and one demonstrating directly that phrasing cues are in reality overshadowing cues. It was suggested that many effects attributed to forgetting may be due to unrecognized overshadowing of memory cues by phrasing cues, giving rise to exaggerated estimates of forgetting. 相似文献
