Basic research in speech and lateralization of language: Some implications for reading disability

Basic research in speech and the lateralization of language is shown to illuminate the problems of reading and some of its disabilities. First, it is pointed out how speech, or language for the ear, differs markedly from reading, or language for the eye. Though the sounds of speech are a very complex code and the optical shapes of written language are a simple cipher or alphabet on the phonemes, we all perceive speech easily but read only with difficulty. Perceiving speech is easy because, as members of the human race, we all have access to a special physiological apparatus that decodes the complex speech signal and recovers the segmentation of the linguistic message. Reading is hard because the phonemic segmentation, which is automatic and intuitive in the case of speech, must be made fully conscious and explicit. The syllabic method supplemented by phonics (used with certain reservations) is suggested for remediation of segmentation problems. Second, it is posited that since the sounds of speech are processed differently from non-speech sounds, the two should not be diagnosed and remediated interchangeably. Third, it is shown that the relationships among cerebral lateralization for language, handedness and poor reading can now be studied more meaningfully because of the recent development of new techniques. A truism often heard in the opening lecture of graduate classes in education is that we have few answers to the problems that beset us, only questions. In the field of reading, the difficulty may be owing at least in part to our impatient attempts to find immediate solutions for the teacher and the student in the classroom, and our consequent neglect of basic research. I should like to suggest today how knowledge of basic research in related disciplines may lead to clues for improving beginning reading instruction and the lot of the disabled reader—if only by affording us a deeper understanding of the reading process.

Visual and phonological determinants of misreadings in a transparent orthography

Growth of word reading skills was examined in first and second year Italian school children by analysis of the pattern of reading errors. The study was designed to investigate the role of visual vs phonological similarities as causes of misreadings in a transparent orthography. The selection of reading material was tailored to permit a meaningful cross-language comparison with pre-existing findings on English-speaking children. The results showed that, in Italian as in English, spatially-related errors (such as confusingb andd) constituted a minor proportion of the total errors. Errors on vowel and consonant letters that are not spatially confusable accounted for the greater proportion of the total. Moreover, the co-occurrence of spatial and phonological confusability resulted in appreciably more errors than when either occurred without the other. Vowel position in the syllable had no systematic effect on errors. In beginning readers of Italian, consonant errors outnumbered vowel errors by a wide margin; the reverse pattern was found in previous studies on English-speaking children at the same level of schooling. It is proposed that differences between Italian and English in the phonological structure of the lexicon and in the consistency of grapheme-phoneme correspondences account in large part for the differences in quantity and distribution of the errors.     

Choice and percentage reinforcement in pigeons

Pigeons responded on a two-key concurrent chains choice procedure with the same level of percentage reinforcement on each key. During the initial links, a choice response on either key occasionally produced a conditioned reinforcer—which on one key was associated with a 15-sec, and on the other key with a 30-sec, interreinforcement interval—or an extinction stimulus. In Part 1, the initial links were equal. With successive decreases in the probability of a reinforcer, choice shifted from preference for the 15-sec terminal link toward indifference. In Part 2, the initial links were unequal and were arranged so that the shorter initial link preceded the 30-sec terminal link. At a high probability of a reinforcer, the pigeons again preferred the 15-sec terminal link. However, at a low probability, the pigeons reversed and preferred the alternate key. It was concluded that the conditioned reinforcers tended to become functionally equivalent at a low probability of a reinforcer, despite the nominally different interreinforcement intervals, with the result that choice was then modulated by the relative size of the initial links. The data are inconsistent with the view that choice and the strength of conditioned reinforcers are isomorphic with the reduction in delay to reward correlated with terminal link stimuli.     

Reading Literacy Performance in Norway: current practice and critical factors

This qualitative study explored reading literacy performance of Norwegian students (Grades 1–10). Semistandardised interviews were conducted with 36 academics, school administrators, and teachers to investigate reading literacy development, factors associated with literacy performance, and recommendations for improvement. Reading literacy lessons were also observed in 10 classrooms to determine how reading literacy is developed. Data from the International Association for the Evaluation of Educational Achievement study ( Elley, 1994 ) and the Programme for International Student Achievement study ( OECD, 2001 ) were analysed to enrich understanding of the Norwegian literacy situation. Recommendations include greater reading education for teachers, communication and collaboration between stakeholders, engagement and interest in reading, balanced reading instruction, development of linguistic awareness, use of early intervention programmes, explicit strategy instruction, and use of bilingual education.     

Middle school teachers’ differing perceptions and use of curriculum materials and the common core

Eight middle school mathematics teachers’ perceptions and uses of curriculum materials and the Common Core State Standards for Mathematics (CCSSM) were investigated. Adapting a noticing framework and models of dialogic instruction and direct instruction, teachers’ noticing practices with curriculum materials and the CCSSM when planning, enacting, and reflecting on lessons were examined. Teachers who were committed to implementing the CCSSM and who were using one of two substantively different curriculum programs were purposefully selected. Data sources included multiple forms of interviews and classroom observations. The teaching evidenced three distinct noticing patterns. These patterns indicated that teachers’ curriculum materials were associated with how teachers perceived and enacted the CCSSM. Teaching with a curriculum program that was designed as a thinking device prioritized the Standards for Mathematical Practice of CCSSM evidenced noticing that was consistent with dialogic instruction. Teaching with a curriculum program that was designed as a delivery mechanism prioritized the Content Standards of CCSSM and evidenced noticing consistent with direct instruction. Findings indicated that the designated curriculum and contributed to differing interpretations of CCSSM and served as a lens for noticing. However, a dialogic curriculum program was not sufficient to support dialogic approaches in practice. One pattern showed teachers planning dialogic lessons, but the lesson enactments were not consistent with teachers’ plans, with evidence that the teachers were not aware that their practices differed from dialogic approaches. Implications for research and practice are discussed.     

Critical Thinking, Epistemic Virtue, and the Significance of Inclusion: Reflections on Harvey Siegel's Theory of Rationality

Among proponents of critical thinking, Harvey Siegel stands out in his attempt to address fundamental epistemological issues. Siegel argues that discursive inclusion of diverse groups should not be confused with rational justification of the outcome of inquiry. He maintains that epistemic virtues such as inclusion are neither necessary nor sufficient for rational judgment, and that if we are to avoid falling prey to relativism, criteria are needed to distinguish which of these virtues are indeed rational. However, the author argues that at least some of Siegel's own rational criteria cannot pass the "necessary or sufficient" standard by which he measures epistemic virtues. Moreover, reliance upon criteria fails to settle conflict in cases of disagreement over what constitutes authoritative evidence. Jürgen Habermas's theory of communicative rationality can help us to overcome this impasse, because it provides a nonrelativistic basis for justifying inclusion and giving it a place of priority in practical reasoning.
