In a replication of an earlier study, the spellings produced by 47 learning disabled (LD) students (ages 7 to 11 years) were classified in terms of a hierarchy of spelling strategies presumed to result in conventional spelling. The developmental trends for the spelling strategies used by the LD Ss were compared to the trends previously observed…

Comparison of 30 learning disabled (LD) children, ages 7 to 13, and controls on a computerized test of attentional skills indicated LD subjects committed more omission errors and responded at a slower rate but did not differ from the controls on commission errors, suggesting inefficient allocation of processing resources rather than attentional…

Children's mental performance was studied in the context of arithmetic word problem solution. Response latency and error data indicated subtraction was more difficult than addition. Understanding children's problem solutions in terms of flexible strategy use and the fact that many errors have a systematic basis are important in studying children's…

Reviews and synthesizes the major findings on reversal errors made by young readers. (FL)

Two studies involved 21 reading disabled elementary students grouped as either dysphonetics (characterized by nonphonetic spelling errors) or dyseidetic readers (characterized by spelling words according to sound rather than appearance). Cognitive strategy differences were noted in visual sequential memory. Findings emphasized the importance of an…

Research recurrently indicates that children who have difficulty with arithmetic often use systematic routines that yield wrong answers. Recent research has focused less on identifying the most common errors among groups of children and more on analyzing individual children's errors. This paper considers the source of systematic errors in…

The informal subtraction strategies that children develop are discussed in detail, with the role of the counting-down strategy described. Problems and remedies for difficulties caused by counting backward and the double count are also presented. (MNS)

Semantic or vocabulary errors were measured among 6 children with autism and mild learning disability (ages 7-8) and 6 with mild learning disability. Vocabulary errors were similar, except under extension, which was not used by children with autism. Children with autism tended to use all mechanisms in order to name something. (Contains…

A study involving 26 Taiwanese children (ages 6-12) with autism and 52 controls found scores on the Wisconsin Card Sorting Test were significantly higher for controls for categories completed and percent conceptual level. Scores on perseverative responses, perseverative errors, and non-perseverative errors were higher for those with autism.…

This study examines the role of verbal labels in picture recognition by 5-year-olds and adults to find out if recognition accuracy and time of recognition choice is influenced by the use of labels. (GO)

A model of subtraction development and the computing difficulties and research issues suggested by the model are outlined. Demands of simultaneous processes, difficulties with informal subtraction, and the impact on the counting-up procedure are discussed. (MNS)

Valuable insights into the reading process can be gained by analyzing children's reading miscues and by encouring children to use their linguistic knowledge when reading. (JH)

This paper analyzes a typical school spelling task in terms of an information processing model of spelling performance. Based on principles embodied in a computer simulation program previously reported (SPEL by Simon and Simon) the model proposed here has been expanded to try to account for many more kinds of student error than were possible with…

Teaching sequences designed to develop strategies for comparing numerals in grade two (in France) were analyzed. Children's strategies were noted, and an experiment confirmed underlying misconceptions concerning number. (MNS)

To examine the association between reversal errors and neurological disorders, 409 first graders were asked to name the letters of the lowercase alphabet presented in fixed, nonalphabetical order. (Author)
