Left anterior lobectomy and category-specific naming

Damasio and colleagues (1996) have proposed that the left anterior temporal region supports knowledge pertaining to living objects, whereas more posterior temporal regions play a critical role in naming nonliving things. Accordingly, one might expect that left-sided anterior temporal lobectomy should have a more profound effect on the naming of living as opposed to nonliving things. As part of a multicenter collaborative project, seventy-nine patients (all left-hemisphere speech dominant) were tested pre- and post-left-temporal lobectomy on a task that required naming of living and nonliving items equated for name frequency, familiarity, and visual complexity. Consistent with the proposals of Damasio et al. (1996), left temporal lobectomy impaired naming ability, particularly for living things. When individual outcomes were considered, twice as many patients showed a relative decline in naming living as opposed to nonliving things.     

Visual angle of the mind's eye before and after unilateral occipital lobectomy.

Do mental images occur in a spatially mapped (i.e., analog, or array-format) representational medium? Kosslyn's (1978) method was used to measure the visual angle of "the mind's eye" to estimate the extent of the imagery medium before and after unilateral occipital lobectomy. It was found that the overall size of the largest possible image was reduced following the surgery. In addition, only the horizontal extent, and not the vertical extent, of the imagery medium was reduced. Finally, it was determined that the S understood the tasks, was not aware of our predictions, and was unaffected by a strong demand characteristic in a different imagery task. These results are consistent with the hypothesis that imagery occurs in a spatially mapped representational medium dependent on occipital cortex.     

词间空格促进从右向左呈现汉语文本的阅读

摘要：为探讨在无阅读经验时,词切分线索是否促进读者的阅读与词汇识别,本研究操纵了阅读方向、词切分线索与目标词的词频。采用眼动仪记录读者的阅读过程。结果发现：阅读方向与词切分线索的交互作用显著,词切分显著地促进了从右向左呈现文本的阅读,但并不影响阅读从左向右呈现的文本;词切分条件下目标词的注视时间显著地短于无词切分条件。表明词切分线索促进了无阅读经验时的阅读,支持词切分线索的促进与文本不熟悉干扰之间权衡作用的假设。     

Investigating the boundaries of reading units across ages and reading levels

In Experiments 1 and 2 first-, third-, and seventh-grade children and college subjects circled the letter a while reading passages constructed of words familiar to first graders. First graders made more errors on the letter a embedded in a word than on the word a, whereas the converse was true of the other age groups. In Experiments 3 and 4 first-, second-, fourth-, and seventh-grade children and college students read passages and circled the letter t, making more errors on the common word the than on other words and on correctly spelled than on misspelled words. The effect of misspelling the other words increased with age and reading skill. Our combined results suggest that reading unit size increases with age and reading ability and that, whereas younger children, like adults, unitize common words, the unitization of less common words increases as word configurations become more familiar.     

Evaluating the effect of parent reading interventions on improving reading fluency of students with reading difficulties

The current study examines the effect of parent reading interventions on the reading fluency of students with reading disabilities. The experimental procedure was carried out in two stages. In the first stage, the Brief Experimental Analysis procedure was followed to determine the most effective reading fluency intervention for all participants, and in the next step, the parental delivery of the selected intervention procedure took place. Brief experimental analysis was used to identify appropriate reading fluency intervention for each participant. Parents were trained to use the intervention strategies with their children. They implemented the procedures during parent‐tutoring sessions at home and results were measured continuously to determine whether generalization occurred. Parent and child satisfaction with the interventions was assessed. Results demonstrated generalized increases in reading fluency in both high‐word‐overlap and low‐word‐overlap passages as a function of parent tutoring. Also, acceptability ratings by children and their parents indicated that they viewed the interventions as acceptable and effective.     

Simplifying reading: applying the simplicity principle to reading

Debates concerning the types of representations that aid reading acquisition have often been influenced by the relationship between measures of early phonological awareness (the ability to process speech sounds) and later reading ability. Here, a complementary approach is explored, analyzing how the functional utility of different representational units, such as whole words, bodies (letters representing the vowel and final consonants of a syllable), and graphemes (letters representing a phoneme) may change as the number of words that can be read gradually increases. Utility is measured by applying a Simplicity Principle to the problem of mapping from print to sound; that is, assuming that the "best" representational units for reading are those which allow the mapping from print to sounds to be encoded as efficiently as possible. Results indicate that when only a small number of words are read whole-word representations are most useful, whereas when many words can be read graphemic representations have the highest utility.     

The interaction between reading skills and reading instruction

Research on the underlying nature of reading disability, exemplified in the present papers, is essentially correlational. Differences in acoustic memory skills, partial cue utilization, or symbol-sound knowledge may be a result rather than a cause of reading skill differences. Suggestions are made on how to untangle the cause-effect problem through longitudinal investigation and careful analysis of some possible interactions between cognitive skills and reading ability.     

Reading fiction and the psychoanalytic experience: Proust on reading and on reading Proust

Reading can at times engage one emotionally and entail inner psychological experiences in ways akin to those in clinical psychoanalysis. In that light, after a general introduction regarding the import of reading, attention is turned to Proust, Freud's literary complement, as an exemplary instance to illustrate those similarities. Ideas of Proust on reading are followed by thoughts on reading Proust, with the ending of Proust's masterpiece used to illustrate a parallel to termination in clinical psychoanalytic experience.     

Effects of reading span and textual coherence on rapid-sequential reading

Subjects’ Comprehension and Memory of Conventional Presentations (Pages) And Rapid, Serial Visual Presentations (Rsvps) Of Text Were Investigated With A Statement-Recognition Test. Texts Were Presented With Sentences in An Intact Or A Scrambled Order At Rates Of 300 And 600 Words Per Minute (Wpm). Subjects’ Memory for Text Meaning And Surface Structure Was Better In 300-Than In 600-Wpm Conditions, And Subjects Retained More Textual Meaning From Coherent than Incoherent Texts Regardless of Display Rates. These Findings Are Inconsistent With the Idea That Rapid Reading Disrupts the Intersentence Integration Processes of Comprehension, but are Consistent With The Hypothesis of Consolidation Limitation: Furthermore, Subjects Were Separated Into Two Groups Based on Their Performance on the Reading Span Test of Daneman And Carpenter (1980). Low-Span Subjects Retained Significantly Less Text Meaning than High-Span Subjects with Pages, But They Did Almost As Well With RSVPs. This Interaction Suggests that the RSVP Technique Could Be Useful For Improving the Reading Abilities of Less Efficient Readers.     

Word association and the acquisition of reading

Two studies relating reading ability to word association responses were carried out. The first involved early readers and matched control children from pre-first-grade classes. There were 29 early readers and 29 nonreading controls matched for age, sex, and IQ. The early readers were found to give significantly more paradigmatic, or same-form-class, responses than the controls. The second study related reading ability, mental age, and word association responses in developmentally delayed teen-agers and young adults, and pre-first-grade children who varied in reading ability. With partial correlation reading ability was found to be related to paradigmatic responding, while mental age was not significantly related. These results indicate that reading acquisition may change word association responses in children through a reorganizing process in the lexicon.The authors would like to thank the Halifax and Dartmouth School Boards for their cooperation. We would also like to thank Paul Cable of Special Education, and the principals and teachers: Beth Conrad, Karen Duerdan, Elaine Fram, Peter Montgomery, Wayne Serebrin, and Bill Schipilow. Their help was greatly appreciated. An earlier version of study 1 was presented at the American Psychological Association meeting in Los Angeles, August 1981.     

A review of research and theory on the relation between oral reading rate and reading comprehension

We review the conceptual and empirical literature on the relation between oral reading rate and reading comprehension. Three lines of conceptual analysis converge on this relation: (a) application of basic behavior analytic principles suggests that fluent decoding should produce better reading comprehension through direct and indirect relations, (b) behavior analytic understanding of the importance of the rate of behavior as developed by Skinner, Lindsley and Haughton implies that higher reading rate contributes to improved comprehension, and (c) cognitive theory of automaticity explicitly states that high rate reading sets the stage for effective comprehension. A wealth of correlational evidence indicates that reading rate and reading comprehension covary. These results have been replicated across elementary grades and across a variety of measures of reading comprehension. However, experimental analyses have not convincingly demonstrated a functional relation between the two. Experimental work has yielded results that are mixed at best. Examination of experimental design issues shows that although this is not a simple relation to investigate, behavior analysts can make major contributions to understanding the possible functional relation between reading rate and reading comprehension.     

Pathways to reading: the role of oral language in the transition to reading

What is the role of oral language in reading competence during the transition to school? Is oral language in preschool best conceptualized as vocabulary knowledge or as more comprehensive language including grammar, vocabulary, and semantics? These questions were examined longitudinally using 1,137 children from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Children were followed from age 3 through 3rd grade, and the results suggest that oral language conceptualized broadly plays both a direct and an indirect role in word recognition during the transition to school and serves as a better foundation for early reading skill than does vocabulary alone. Implications of these findings are discussed in terms of both theoretical models of early reading and practical implications for policy and assessment.     

How reading braille is both like and unlike reading print

The letter detection errors of blind readers of braille were compared with those of sighted readers of print in order to determine whether braille can be read in units larger than the individual braille character. Sighted readers missed a disproportionate number ofhs in the wordhe whether the prose was intact or scrambled, supporting Healy’s (1976) conclusion that high-frequency words are read in units larger than the individual letter. By contrast, blind readers missed only a disproportionate number ofhs inhe when reading prose, suggesting that their detection failures were based on redundancy rather than unitization. Although the unit of perception for braille appears to differ from that for print, the factors underlying braille comprehension ability do not. Braille comprehension was correlated with listening comprehension and working memory capacity, a finding consistent with the visual reading literature which has shown that it is the higher level linguistic processes that tax working memory capacity and not the lower level visual word encoding processes that chiefly underlie individual differences in comprehending print.
