Performance determined instruction for training in remedial reading

A system called Performance Determined Instruction (PDI) is presented as a methodological tactic for training in remedial reading. The system incorporates aspects of binary logic, instrumental conditioning, and programmed instruction. Results suggest that PDI is a high-precision instructional procedure effective in obtaining desired changes in reading-task performance.     

Comparison of four scoring methods for the reading span test

This study compared four common methods for scoring a popular working memory span task, Daneman and Carpenter’s (1980) reading span test. More continuous measures, such as the total number of words recalled or the proportion of words per set averaged across all sets, were more normally distributed, had higher reliability, and had higher correlations with criterion measures (reading comprehension and Verbal SAT) than did traditional span scores that quantified the highest set size completed or the number of words in correct sets. Furthermore, creation of arbitrary groups (e.g., high-span and low-span groups) led to poor reliability and greatly reduced predictive power. It is recommended that researchers score span tasks with continuous measures and avoid post hoc dichotomization of working memory span groups.     

Phonological dyslexia: a test case for reading models

Following brain damage, skilled readers may encounter more severe problems in reading nonwords than familiar words, a type of deficit referred to as phonological dyslexia. We report on 2 individuals with Alzheimer's disease who show phonological dyslexia. Although highly accurate in reading familiar words aloud (even those with irregular spelling, such as sew), they were quite impaired in nonword reading. Both patients performed well in phonological tasks involving the repetition, identification, and manipulation of phonemes of orally presented words and nonwords. These results challenge the idea, proposed in the context of connectionist and evolutionary theories, that phonological dyslexia originates from a phonological deficit. However, the results are consistent with reading models, such as the dual-route model, that attribute phonological dyslexia to a deficit that selectively affects the reading mechanisms responsible for deriving the sounds of nonwords. According to these models, such a deficit is not necessarily accompanied by a more general phonological impairment.     

The woodcock reading mastery test: impact of normative changes

This study examined the magnitude of differences in standard scores, convergent validity, and concurrent validity when an individual's performance was gauged using the revised and the normative update (Woodcock, 1998) editions of the Woodcock Reading Mastery Test in which the actual test items remained identical but norms have been updated. From three metropolitan areas, 899 first to third grade students referred by their teachers for a reading intervention program participated. Results showed the inverse Flynn effect, indicating systematic inflation averaging 5 to 9 standard score points, regardless of gender, IQ, city site, or ethnicity, when calculated using the updated norms. Inflation was greater at lower raw score levels. Implications for using the updated norms for identifying children with reading disabilities and changing norms during an ongoing study are discussed.     

The relation between oral reading miscue patterns and comprehension: A test of the relative explanatory power of psycholinguistic and interactive views of reading

The use of oral reading to assess silent reading ability has gained wide acceptance despite the lack of definitive evidence that the two processes are similar. Moreover, there are a number of theoretical positions that run counter to assumptions underlying oral reading error analysis as a measure of silent reading competency. This study examined the relation between multiple oral reading miscue measures and postreading comprehension performance. Correlations between the oral reading and comprehension measures indicated a negative relation between oral reading and recall following the reading of familiar passages and a positive relation between oral reading and an inferential comprehension measure following the reading of unfamiliar passages. In addition, when the subjects read disrupted passages, their attempts at correcting incongruous errors and their self-report interviews indicated that their oral reading was not related to their performance on comprehension product measures. The results, which are discrepant with previous research relating oral reading to comprehension, are discussed in terms of a comparison between psycholinguistic and interactive models of reading comprehension.     

Implementing a long-term computerized remedial reading program with synthetic speech feedback: Hardware,software, and real-world issues

This paper discusses hardware choices, software developments, implementation issues, and preliminary results from an ongoing long-term remedial reading study. Reading-disabled children read books on microcomputers linked to speech synthesizers, obtaining speech feedback on difficult words at whole-word, syllable, or subsyllable levels of segmentation. Word-recognition ability and attitude about reading improved for children using the system. In addition, segmented feedback especially benefited phonological word-decoding skills for most of the children.     

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.
