The effect of long-term knowledge upon performance in short-term memory tasks was examined for children from 5 to 10 years of age. The emergence of a lexicality effect, in which familiar words were recalled more accurately than unfamiliar words, was found to depend upon the nature of the memory task. Lexicality effects were interpreted as reflecting the use of redintegration, or reconstruction processes, in short-term memory. Redintegration increased with age for tasks requiring spoken item recall and decreased with age when position information but not naming was required. In a second experiment, redintegration was found in a recognition task when some of the foils rhymed with the target. Older children were able to profit from a rhyming foil, whereas younger children were confused by it, suggesting that the older children make use of sublexical phonological information in reconstructing the target. It was proposed that redintegrative processes in their mature form support the reconstruction of detailed phonological knowledge of words.  相似文献

The D (dissemination) phase of the ESID model has been often overlooked in our efforts to create innovative and widespread social change. The process of replicating successful social innovations is both a prerequisite for dissemination (in order to assess the consistency of effects) and an obvious outcome of a successful dissemination effort. Fidelity, the extent to which a replicated program is implemented in a manner consistent with the original program model, is an important dimension of replication. This study was designed to provide empirical data related to three questions. Can complex social programs be implemented with fidelity? How much fidelity is appropriate or desired? What are the organizational dynamics of adoption with fidelity? Data were collected from grantees of a national replication initiative funded by the Center for Substance Abuse Prevention. Data suggest that high fidelity can be achieved, at least in the context in which programs are mandated to do so as part of the funding agreement and are given technical assistance in achieving fidelity. Secondly, programs perceived high fidelity as having positive effects on the program and its participants, a finding consistent with a limited assessment of the relationship of program outcomes and fidelity. Finally, much was learned about the human and organizational dynamics of replicating with fidelity. Implications for policy and direction regarding replication are discussed.  相似文献

This study investigated the effects of school mobility on reading and math achievement for 1,087 low-income Black children in the Chicago Longitudinal Study. Between kindergarten and seventh grade, 73% of the students changed schools at least once during elementary school and 21% changed schools three or more times. The prospective longitudinal design of the Chicago Longitudinal Study allowed for controlled analyses of both the predictors and the consequences of school mobility. The significant predictors of the number of moves included prior achievement, the number of years of preschool participation in an education intervention program, and parent education. Although the students who changed schools frequently between kindergarten and seventh grade performed approximately one year behind their nonmobile peers on reading and mathematics achievement tests taken at the end of seventh grade, only one half of this difference appears attributable to frequent mobility. The remaining portion is due to the fact that the mobile students were lower achieving even before they started to change schools. The negative consequences of past school mobility are lower for students who moved into better quality schools such as magnets or academic academies. Findings indicate that it is frequent, rather than occasional, mobility that significantly increases the risk of underachievement.  相似文献

Children with early brain damage, unlike adult stroke victims, often go on to develop nearly normal language. However, the route and extent of their linguistic development are still unclear, as is the relationship between lesion site and patterns of delay and recovery. Here we address these questions by examining narratives from children with early brain damage. Thirty children (ages 3;7–10;10) with pre- or perinatal unilateral focal brain damage and their matched controls participated in a storytelling task. Analyses focused on linguistic proficiency and narrative competence. Overall, children with brain damage scored significantly lower than their age-matched controls on both linguistic (morphological and syntactic) indices and those targeting broader narrative qualities. Rather than indicating that children with brain damage fully catch up, these data suggest that deficits in linguistic abilities reassert themselves as children face new linguistic challenges. Interestingly, after age 5, site of lesion does not appear to be a significant factor and the delays we have witnessed do not map onto the lesion profiles observed in adults with analogous brain injuries.  相似文献

Researchers identified personality typologies (Myers-Briggs Type Indicator; Myers, 1962) among urban African American high school Juniors and seniors (n = 173). Introverted Sensing Thinking Judging (ISTJ) and the Introverted Sensing Thinking Perceptive (ISTP) were the two most represented typologies. Implications for school counselors, teachers, and teacher and counselor educators are discussed.  相似文献

Summary The role of attention and the resolution of coding conflicts in hand-hemispace spatial-compatibility effects was examined in a precueing experiment in which visual and vibrotactile precues, with various stimulus-onset asynchronies (SOAs), were presented in blocked and random order. It was expected that precues at the shorter SOAs would fail to facilitate the shifting of attention, as they occur too close to the imperative stimulus to be informative. The task would therefore approximate one of choice reaction time (RT), resulting in a hand-hemispace spatial-compatibility effect. Conversely, the longer SOAs would provide the subject with sufficient time in which to shift attention fully, and would therefore result in a task more like that of simple reaction time (SRT). It was expected that the hand-hemispace spatial-compatibility effect would then be absent. As was expected, this effect was present at the shorter SOAs, and absent at the longer SOAs. In Experiments 2 and 3, provision of a visual precue further facilitated attentional deployment, as did blocking the presentation of various SOAs in Experiment 3. Vibrotactile and visual precues did not differ in their ability to direct attention, implying that these modalities orient attention and precue location in essentially similar ways. These findings are discussed within the context of the mechanisms thought to underlie the time course of spatial compatibility and the dissipation of a fading trace of interfering spatial codes.  相似文献

Symptoms of somatization were investigated in pediatric patients with recurrent abdominal pain (RAP) and comparison groups of patients with organic etiology for abdominal pain and well patients. Somatization scores were higher in RAP patients than well patients at the clinic visit, and higher than in either well patients or organic patients at a 3- month followup. Higher somatization scores in mothers and fathers were associated with higher somatization scores in RAP patients, but not in organic or well patients. Contrary to the findings of Ernst, Routh, and Harper (1984), chronicity of abdominal pain in RAP patients was not significantly associated with their level of somatization symptoms. Psychometric information about the Children's Somatization Inventory is presented.This research was supported by grants from the Vanderbilt University Research Council and from the National Institute of Child Health and Human Development (HD2364). Garber was supported in part by the W. T. Grant Foundation Faculty Scholar program during completion of this work. The authors are grateful for the assistance of Fayez K. Ghishan, Harry L. Greene, and Patty Vieira of the Vanderbilt Division of Pediatric Gastroenterology.  相似文献

Participants rated 84 statements adapted from Velten's original mood induction statements—designed to induce positive and negative mood—on two dimensions of emotion (valence and arousal), using the Self Assessment Manikin (SAM) (P. J. Lang, M. M. Bradley, & B. N. Cuthbert, 1999). Fifty-two of these Velten positive, negative, and neutral statements yielded SAM valence ratings that were consistent with Velten's previous valence designation (E. Velten, 1968). Reliability analyses for the positive, negative, and neutral statements indicated a high level of internal consistency in the three statement groups. Arousal and valence ratings of the statements were positively correlated. Related issues concerning differences in rating verbal versus visual emotional stimuli and recommendations for future work to improve the validity of Velten's mood induction statements are addressed.  相似文献
