Relations among musical skills,phonological processing,and early reading ability in preschool children 总被引:1,自引:0,他引:1

We examined the relations among phonological awareness, music perception skills, and early reading skills in a population of 100 4- and 5-year-old children. Music skills were found to correlate significantly with both phonological awareness and reading development. Regression analyses indicated that music perception skills contributed unique variance in predicting reading ability, even when variance due to phonological awareness and other cognitive abilities (math, digit span, and vocabulary) had been accounted for. Thus, music perception appears to tap auditory mechanisms related to reading that only partially overlap with those related to phonological awareness, suggesting that both linguistic and nonlinguistic general auditory mechanisms are involved in reading. 相似文献

The place at which the eyes first fixate in a word during continuous reading, called the preferred landing position (PLP), is usually located halfway between the beginning and the middle of the word. To propose a mechanism that might account for the off-center location of the PLP, six eye movement experiments were conducted using a lexical decision task (Experiment 1) and a stimulus bisection task (Experiments 2-6). The type of stimulus--linguistic (words and nonwords) versus nonlinguistic (strings of hashes, dotted lines, and solid lines)--and the stimulus presentation side (left vs. right) were manipulated. The results showed that (1) stimulus discreteness versus continuousness is an important factor in saccade computation and (2) PLP asymmetry can be explained in terms of attentional and/or oculomotor processes. 相似文献

Recent models of lexical processing suggest that written spelling partly depends upon the semantic system. According to these models, a deterioration in word meanings would necessarily lead to a spelling impairment, especially for low-frequency and orthographically irregular words. We report a case study of a patient (MK) with semantic dementia who presents impairments in knowledge of word meanings and surface dysgraphia. By specifically identifying concepts that are still known or that are partially or completely deteriorated, we show that the patient's spelling deficit is highly correlated with word comprehension. These data confirm that surface dysgraphia is directly linked to the breakdown in semantic memory. 相似文献

The effects of aging and dorsal hippocampal lesions: performance on spatial and nonspatial comparable versions of the water maze 总被引:3,自引:0,他引:3

Aged intact and young hippocampal-lesioned rats show similar deficits on the spatial water maze. However, this does not necessitate that the source of these deficits in the aged animals is due to hippocampal damage. These water maze deficits may arise from other aging factors such as changes in thermoregulation, muscle fatigue, swim ability, and response to stress. Consequently, it is imperative to examine the performance of aged rats on a comparable nonhippocampal version of this task. Past attempts to develop a hippocampus-independent version of the water maze were confounded because these tasks were easier (i.e., the rats spent much less time swimming in the water) than the spatial versions of the task. The current study examined performance on a hippocampus-independent task comparable in difficulty to the spatial water one. Middle-aged (16-m) and old (25-m) male F344 rats were given sham or dorsal hippocampus lesions and tested on both a spatial and a nonspatial water maze. The middle-aged rats with hippocampal lesions were impaired on the spatial task but not on the nonspatial task. Conversely, aged animals showed a similar impairment on both types of water maze tasks. Additionally, hippocampal lesions exacerbated the age-related impairment on both tasks. These findings indicate that caution must be used when interpreting the results of water maze tasks for aged animals. 相似文献

Empirical data from research studies are vital to guiding mental health interventions following disasters. However, few data are available for this purpose. Important advances in policy and procedures for the conduct of organized research emerged from the Oklahoma City bombing, yielding cooperative working relationships among researchers and culminating in the ethical attainment of informative research data. However, the academic community was again caught off guard after the September 11, 2001, terrorist attacks. Suggestions to surmount these obstacles include incorporating research infrastructures into disaster preparedness plans in advance; organizing the community of researchers; and working closely with major funding organizations. Methodological issues pertaining to measurement of psychopathology include the importance of obtaining diagnostic data; interpreting the meaning of symptoms in the absence of a psychiatric disorder; differentiating preexisting symptoms from those that emerged after the disaster, and optimal timing of postdisaster assessment. 相似文献

Spatial working memory (SWM) is known to be impaired in children with ADHD-CT, whether anxiety is present or not. Yet, it remains unclear whether anxiety disorders add to the SWM impairments evident in ADHD-CT and whether these findings extend into adolescents with ADHD-CT and anxiety. Further, it is not yet known whether children and adolescents with carefully defined anxiety disorders alone, demonstrate SWM deficits. This study explored the association of SWM and its strategy and spatial span components in carefully defined children and adolescents (age 6–16 years) with ADHD-CT alone (N?=?163; 14 % female), ADHD-CT and anxiety (N?=?243; 23 % female), anxiety disorders alone (N?=?69; 25 % female) compared to age- and gender-matched healthy control participants (N?=?116; 19 % female). The relationship between SWM and its strategy and span components and core ADHD-CT symptoms and anxiety symptoms were also examined. There was no evidence of an additive effect of ADHD and anxiety on SWM, strategy and spatial span deficits. But, anxiety disorders alone were associated with impaired SWM and span performance compared to healthy control participants. In contrast, strategy did not differ between children and adolescents with anxiety disorders alone and healthy control participants, suggesting that with anxiety span is the most affected component. Further, these findings were age-independent. This study concurs with and extends current influential models about the cognitive effects of anxiety on performance in the setting of ADHD-CT. Clinical implications and future research directions are discussed. 相似文献

First and second grade public school teachers were trained through interactive video-conferencing to implement Language Enrichment, an Orton-Gillingham-based literacy instruction. The effectiveness of the linguistically informed training was demonstrated by documenting the longitudinal third grade reading comprehension achievement of their students. Student achievement was measured on the state-mandated achievement test, Texas Assessment of Academic Skills (TAAS). Hierarchical linear modeling (HLM) showed that students whose teachers were trained in Language Enrichment instruction had higher third grade reading comprehension achievement than students whose teachers were not trained. Additionally, a significant effect of the length of Language Enrichment teaching experience of the second grade teacher on third grade reading comprehension was found. Earlier occurring second grade teacher training was associated with higher reading scores than later training. Based on these findings it is suggested that teachers who have content-rich knowledge known to support literacy acquisition can provide reading instruction that results in a level of reading comprehension that is significantly higher than that resulting from teachers who do not have a well-developed domain of knowledge concerning the reading process. This study also indicates that teacher competence was enhanced through practice because student reading achievement of the more-experienced Language Enrichment teachers was higher than that of the less-experienced Language Enrichment teachers. 相似文献

This article reports the outcomes of the first 3 years of an ongoing participatory action research (PAR) project that brought together literacy and content-area teacher educators. The purpose of our collaboration was two-fold: (a) to develop shared understandings or theories related to literacy and the place of literacy instruction in content-area classrooms, and (b) to make changes to our work with preservice teachers in order to prepare them to support adolescents’ content learning and discipline-specific literacy development. The findings reveal that the collaborative activities allowed participants to embrace broad notions of text and literacy that are useful in making sense of disciplinary aims and pedagogy. Furthermore, as teacher educators came to shift their thinking about literacy and disciplinary learning and teaching, their work with preservice teachers changed. Implications for future collaborative activities to promote content-area literacy are discussed. 相似文献

Previous research has suggested that we tend to show impaired memory for self-threatening information, an effect known as mnemic neglect. Mnemic neglect is believed to be due to shallow processing or inhibition of self-threatening information. Mnemic neglect, however, could also be an example of experiential avoidance and mindfulness training has been demonstrated to counteract experiential avoidance. The current study was designed to negate experiential avoidance on a memory task via mindfulness training and attempt to increase recall of self-threatening information. Participants were exposed to a short intervention, either mindfulness or unfocused attention, before being instructed to read and later recall self-referent behaviors. The findings indicated that recall of self-threatening and other self-referent information was increased following the mindfulness but not unfocused attention intervention. The utility of mindfulness as a strategy for negating the experiential avoidance normally associated with self-threatening information and increasing memory performance are discussed. 相似文献

This study examined the role of intimate partner victimization in mediating the relationship between childhood sexual abuse and adulthood parenting in a community sample of mothers reliant on public assistance (N = 483). Baron and Kenny's (1986) method for establishing mediation was used to address this question. A recent history of intimate partner violence mediated the relationship between childhood sexual abuse and psychological aggression; however, a lifetime history of intimate partner violence did not. Depressive symptomatology was found to mediate the relationship between childhood sexual abuse and parental warmth. The impact of childhood sexual abuse on corporal punishment was indirect through its association with childhood physical abuse and witnessing domestic violence. Implications for research, theory development, and practice are provided. 相似文献
