This study reports on several specific neurocognitive process predictors of reading outcomes for a sample of 278 children with reading disabilities. Three categories of response (i.e., poor, average, and good) were formed via growth curve models of six reading outcomes. Two nested discriminant function analyses were conducted to evaluate the predictive capability of the following models: (a) an intervention and phonological processing model that included intervention group, phonological awareness, and rapid naming and (b) an additive cognitive neuropsychological model that included measures of memory, visual processes, and cognitive or intellectual functioning. Over and above the substantial explanatory power of the base model, the additive model improved classification of poor and good responders. Several of the cognitive and neuropsychological variables predicted degree of reading outcomes, even after controlling for type of intervention, phonological awareness, and rapid naming. 相似文献

According to the Lexical Restructuring Model (Metsala & Walley, 1998), children move from holistic representations of words, to syllabic representations, and finally to phonemic representations through a restructuring process driven by their developing lexical base. In contrast, the psycholinguistic grain size theory put forth by Ziegler and Goswami (2005) suggests that the awareness of individual phonemes is not possible without direct literacy instruction. The purpose of this study was to examine whether semantic knowledge and/or knowledge of grapheme/phoneme correspondences influenced the acquisition of word-blending skills by a sample of children with a reading disability. Participants were 211 second-grade and third-grade students from public elementary schools who were assigned to a reading intervention. Hierarchical Linear Modeling techniques were used to model individual growth curves of word-blending skills. Overall, findings support the psycholinguistic grain size theory of reading and suggest that instruction in the relationship between orthographic patterns and their corresponding sounds is necessary for the development of phonological awareness. 相似文献

In human movement and sports science, manipulations of perception and action are common and often comprise the control of events, such as opening or closing liquid crystal goggles. Most of these events are externally controlled, independent of the actions of the participants. Less common, although sometimes desirable, are event manipulations that are dependent on the unconstrained movements of participants. As an example, we describe a method we used previously to manipulate vision of basketball jump shooters on the basis of on-line registration of their own movements. The shooters wore liquid crystal goggles that opened or shut as a function of specific kinematic features of these movements. The novel aspect of this method is that the criteria for detecting movement patterns and performing the appropriate manipulations are adjustable to the specific sport context and the complexity and variations of the unconstrained movements. The method was implemented as a finite state machine: a computer system that can be used for pattern recognition. We discuss this method, how it works and the potential it has for studying perceptual-motor skills in sport. Furthermore, the results of the basketball experiment are briefly summarized and complemented with new analyses. 相似文献

Four methods of identifying change in the context of a multiple component reading intervention for struggling middle school readers 总被引：1，自引：0，他引：1

The results from controlled intervention research have indicated that effective reading interventions exist for children with reading difficulties. Effect sizes for older struggling readers, however, typically have not matched the large effects demonstrated with younger children. Standardized effect sizes for intervention/control comparisons obscure important individual differences within intervention and control groups—differences potentially relevant to the who and why of intervention success. The present study reports the outcomes of PHAST Reading, a research-based multiple component reading intervention. Participants were 270 Grade 6, 7, and 8 students reading significantly below age-level expectations, who participated in a year-long intensive small-group intervention. Four methods were applied to characterize individual change: (a) normalization relative to age-appropriate standards; (b) statistically-reliable pre–post change using the Jacobson–Truax index; (c) individually-estimated growth rates using hierarchical linear modeling; and (d) change to a fixed criterion across multiple measures. Each method was evaluated for its ability to identify intervention outcomes, replicate traditional group-based effect size metrics, and characterize individual differences across participants depending on whether change was demonstrated. Each method replicated traditional group-based effect sizes, with advantages in consistency and predictive power for the reliable change index and growth curve approaches. 相似文献

Relationship between home literacy environment and reading achievement in children with reading disabilities 总被引：3，自引：0，他引：3
Past research has indicated that a significant relationship exists between young children's early home literacy environment and their reading-related skills. However, this relationship has rarely been investigated among older children with reading disabilities (RD). In the present study, the relationship between parent and child home literacy activities and children's academic functioning was investigated with a sample of 65 elementary-age children with RD. The results indicated that children's home literacy activities were not significantly related to any of their academic abilities, whereas parents' home literacy activities were significantly related to children's passage comprehension and spelling scores. However, relationships between home literacy environment and reading may be different for children with and without RD. 相似文献

2 common chimpanzees and 1 pygmy chimpanzee, all of whom were proficient lexigram symbol users, were tested on symbolic cross-modal tasks. Previous cross-modal work with nonhuman primates has been limited to nonsymbolic matching tasks. None of these chimpanzees received any advance training on cross-modal tasks prior to the testing reported here. The common chimpanzees, Sherman and Austin, were tested on visual to haptic, visual-symbolic to haptic, haptic to visual-symbolic, and olfactory to visual-symbolic matching tasks. The pygmy chimpanzee, Kanzi, was tested on auditory-symbolic to pictorial and auditory-symbolic to visual-symbolic matching tasks. All subjects were able to match stimuli across the tested dimensions with no training. These results indicate that chimpanzees who have received symbol training can perform symbolic cross-modal tasks similar to those that are typically used with human subjects. These tasks require not only cross-modal associations but also the transformation of information from symbolic to representational modes. 相似文献

Achievement and cognitive tests are used extensively in the diagnosis and educational placement of children with reading disabilities (RD). Moreover, research on scholastic interventions often requires repeat testing and information on practice effects. Little is known, however, about the test-retest and other psychometric properties of many commonly used measures within the beginning reader population, nor are these nationally normed or experimental measures comparatively evaluated. This study examined the test-retest reliability, practice effects, and relations among a number of nationally normed measures of word identification and spelling and experimental measures of achievement and reading-related cognitive processing tests in young children with significant RD. Reliability was adequate for most tests, although lower than might be ideal on a few measures when there was a lengthy test-retest interval or with the reduced behavioral variability that can be seen in groups of beginning readers. Practice effects were minimal. There were strong relations between nationally normed measures of decoding and spelling and their experimental counterparts and with most measures of reading-related cognitive processes. The implications for the use of such tests in treatment studies that focus on beginning readers are discussed. 相似文献

Phonological awareness (PA) and rapid automatised naming (RAN) skills in relation to reading acquisition were examined using two languages, one with a deep orthography (English) and the other with a shallow orthography (Korean). Participants were 50 Korean American children who spoke English as a dominant language (DL) and were learning to read Korean as a sequential language (SL). Parallel measures in English and Korean assessed PA, RAN and reading skills. The results showed the similarities and differences between the DL and SL acquisition patterns for PA and RAN. While PA skills of the DL were a dominant predictor in SL reading achievement, RAN became important for the children with the higher level of SL reading performance. This cross‐sectional study indicates that proficiencies of PA and RAN in the DL are the pathway to reading success in an SL. This suggests that a universal thread exists in learning dual languages, despite dissimilar orthography, phonology and writing systems. 相似文献
