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

The aim of the study was to determine if spontaneous play was altered in 2-year-olds born to polysubstance-abusing mothers. The study is part of a longitudinal research project of chronic substance-abusing mothers and their children living in poverty in the inner city of Los Angeles, identified in the hospital at birth by positive urine-toxicology screens, and compared to non-substance-abusing mothers and their children living in the same geographic area, of similar ethnic group and socioeconomic and marital status. The behavior of the 31 target and 21 comparison children in the 16-minute procedure was measured by frequency counts of manipulative, functional, and symbolic acts as well as by ratings of the quality of play. The play of the prenatally drug-exposed children differed from the comparison group by demonstrating significantly more immature play strategies, less sustained attention, more deviant behaviors, and fewer positive social interactions with their caregivers.  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

Matching the emotional expressions of pairs of face photos was slower with pixelated and blurred photos than with original, untransformed photos. Matching the identities of the same face pairs was unaffected by pixelation and blurring. Because pixelation and blurring degrade higher spatial frequencies carrying edge-based information that define feature shape more than lower frequencies carrying configural properties, these findings converge with findings for line drawings and negative photos in showing that expression and face recognition processes differ in their reliance on edge-based and configural information.  相似文献
