The purpose of this study was to investigate how brief experimental analyses (BEAs) could be used to identify effective interventions for Kindergartners (2 girls and 2 boys, 5 years and 7-10 months old) with low performance and/or growth slope in letter sound fluency (LSF). Interventions were tested within a multielement design with brief mini-reversals until an intervention yielding at least 20% improvement on a specific subskill measure or a curriculum-based measure of LSF was identified. BEA-identified interventions were implemented one-on-one for 5 to 9 weeks. A multiple-baseline design across participants showed large intervention effects (average adjusted d = 2.4) on general outcome measures, supporting treatment validity of BEAs. Findings extend the BEA literature to younger participants, early reading interventions, and early reading measures. 相似文献

This study examined patterns of growth across benchmark assessments for curriculum-based measures (CBM) over 2 academic years, with the twofold purpose of replicating earlier findings of growth patterns on R-CBM and conducting a preliminary investigation of growth patterns on M-CBM and CBM-Maze. The sample included 898 cases from 3rd through 5th grade over 2 academic years from one elementary school in the rural Midwest. All students participated in tri-annual benchmark assessments in which they were administered R-CBM, CBM-Maze, and M-CBM. Repeated measures analysis of variance was used to examine patterns of growth for all three measures. Students demonstrated greater R-CBM weekly growth during winter-to-spring than fall-to-winter across grade levels. Patterns for CBM-Maze and M-CBM were somewhat inconsistent across school years and grade levels. Results are discussed in terms of contextual variables that may impact within-year growth patterns and technical characteristics of CBM slopes. 相似文献

The present study investigated cerebral asymmetries in accessing multiple meanings of two types of homographs: homophonic homographs (e.g., bank) and heterophonic homographs (e.g., tear). Participants read homographs preceded by either a biasing or a non-biasing sentential context and performed a lexical decision on lateralized targets presented 150 ms after onset of the sentence-final ambiguous prime. Targets were either related to the dominant or the subordinate meaning of the preceding homograph or were unrelated to it. In the case of homophonic homographs – our results converge with previous findings: both activation and selection processes are faster in the LH than in the RH. Importantly, however, in the case of heterophonic homographs – opposite asymmetries were found. These results suggest that semantic asymmetries are modulated by phonology. They are discussed in the context of a model of functional architecture of reading in the two hemispheres in which orthography, phonology and semantics are fully interconnected in the LH, whereas in the RH, orthography and phonology are not directly connected, such that phonological processes are mediated by semantics. 相似文献

Brief experimental analyses (BEA) have been used to identify effective individualized interventions for improving reading
fluency with school-age children. Interventions involving incentives, modeling, repeated reading, and error correction are
most often tested in a BEA. However, these interventions are rarely modified according to individual student needs. The current
study examined the effects of varied levels of modeling (passage, sentence, word) and varied contingencies (tracking and fluency)
on fluency in non-treated high-word overlap passages and general outcome measure passages. BEA-identified interventions were
effective for improving reading fluency on non-treated passages for both second grade students and the third grade student.
Notably, the effects reversed when intervention was withdrawn with one of the second grade students. Results are discussed
in terms of considerations in the application of BEA technology in the schools. 相似文献

Ellis, Ansorge and Lavidor (2007) [Ellis, A.W., Ansorge, L., & Lavidor, M. (2007). Words, hemispheres, and dissociable subsystems: The effects of exposure duration, case alternation, priming and continuity of form on word recognition in the left and right visual fields. Brain and Language, 103, 292–303.] presented three experiments investigating the effects of exposure duration and format (normal vs mixed or alternating case) on the recognition of words presented in the left and right visual fields. The experiments were conducted within the framework of ‘dissociable neural subsystems theory’ developed by Marsolek and colleagues. Marsolek and Deason (2007) [Marsolek, C.J. & Deason, R.G. (2007).

学习困难儿童的元记忆监测与控制特点 总被引:13,自引:2,他引:11
以有无意义联系的两种中文词对为材料,采用2×3×2混合实验设计,对小学三到五年级学习困难儿童的元记忆监测、控制水平与学优儿童之间的差异及其发展特点进行研究。结果表明:1.学习困难儿童在三种元记忆监测判断等级上均显著低于学优儿童。2.学习困难儿童具有元记忆控制能力,但其控制水平相对低于学优儿童。3.学习困难儿童的元记忆监测判断和学习时间分配之间存在交互影响。4.学习困难儿童的元记忆监测和控制水平存在较为复杂的发展特点。据此得出结论认为,学习困难儿童的元记忆监测与控制能力都比学优儿童差,同时也表现出一定的发展趋势。 相似文献

In a long-term study two groups of language and reading impaired students ( N = 15 + 15) were reading with the aid of segmented speech-feedback in a computerized program. One group received feedback that was simultaneously segmented visually and auditorily into syllables, the other received feedback by letter names. In both groups subjects were expected to synthesize segments into words and to compare their synthesis to whole word feed-back subsequently provided by the computer. They worked for half a lesson (approximately 20 minutes) a day for a total of 40 days. During this period, the experiment groups progressed more in reading than a control group of age and reading-level-matched students ( N = 35) who received traditional remedial instruction. The group in the syllable condition gained slightly more in non-word reading and in syllable segmentation than did the letter group. Differences in gains in reading abilities were not explained by differences in age, but to some extent by initial level of phoneme and syllable awareness. Future applications of the speech-feedback system are discussed. 相似文献

Two experiments were performed to test the hypothesis that omission of a previously received reward is followed by greater motivation to obtain that specific reward, as compared with the case where the reward had been present. In Experiment 1, experimental rats regularly received food rewards (Ra) at one goal, followed by a choice between food and milk (Rb). Control animals received the same choice without food preceding it. Reward magnitudes were manipulated so as to produce a preference for Rb, and additional forced trials were given each day to equalise experience of the two rewards. In the test phase both groups received trials with Ra present (R) or absent (N) at the first goal. The experimental Ss shifted their choice towards Ra on N trials; the controls did not behave differently after R and N. Experiment 2 was similar, except that Ra was milk and Rb food. The same effect of N on experimental animals was obtained. It is argued that the results are relevant to the double-runway ‘frustration effect’, and cannot be explained by existing theories of frustration. 相似文献
