In this large-scale study of students from Title 1 schools (N = 14,773), we used multiple-group latent change score (LCS) modeling to investigate the developmental relations between vocabulary knowledge and reading comprehension in students with a school-identified learning disability (LD; n = 627) and typically developing students (n = 14,146).…

No previous empirical study has investigated whether the learning disabilities (LD) identification decisions of proposed methods to operationalize processing strengths and weaknesses approaches for LD identification are associated with differential treatment response. We investigated whether the identification decisions of the…

Explanations of the marked individual differences in elementary school mathematical achievement and mathematical learning disability (MLD or dyscalculia) have involved domain-general factors (working memory, reasoning, processing speed, and oral language) and numerical factors that include single-digit processing efficiency and multidigit skills…

This work examines the association between symbols and their representation in adult developmental dyscalculia and dyslexia. Experiment 1 used comparative judgment of numerals, and it was found that in physical comparisons (e.g., 3-5 vs. 3-5) the dyscalculia group showed a significantly smaller congruity effect than did the dyslexia and the…

A study of 12- to 15-year old boys, grouped as learning disabled or nonlearning disabled suggested that learning disabled youths do not evidence more delinquent behavior than nondisabled youths. They are, however, more likely to be found delinquent by juvenile courts. (CE)

A developmentally sensitive problem-solving task--the 20-Question Game--was used to examine development and treatment variables among 48 learning disabled and 48 normal boys at two age levels (8-13 years old). Results indicate that both younger boys and learning disabled boys demonstrated less efficient problem-solving skills than did others. (TJH)

Ten learning-disabled adolescents (LDs) performed a reading comprehension task below the level of same-age nondisabled students (NLDs) but at the same level as younger NLDs (YNDs). On a measure of incipient awareness of theme, LDs scored below YNDs. Why LDs have difficulty getting the point is discussed. (SLD)

A test of whether metacognition is a separate factor from cognition was conducted by measuring the effects of metacognitive factors in problem solving, while attempting to hold relevant cognitive factors constant. Learning disabled subjects were less skilled in metacognition with respect to knowledge about cognition and regulation of cognition.…

This study compared the causal attribution by sex for academic failures of 38 learning disabled and 38 nondisabled elementary school students. The relationship between different attributional tendencies and a reading persistence task were also examined. (BS)

Three studies of language comprehension skills compared 9- and 10-year-old learning-disabled children (LDC) with difficulty retaining verbal information (n=8) with LDC with normal memory spans (n=8) and normally achieving children (n=16). LDC did not have significant impairments in listening comprehension. However, LDC may experience difficulties…

Research in self-regulated strategy development (SRSD) in composition was extended by comparing 43 learning-disabled fifth and sixth grade students in 4 conditions of SRSD instruction. Posttests indicated greater improvement for SRSD conditions with and without goal setting and self-monitoring than for the practice control condition. (SLD)

Social adjustment of 46 children with and 199 children without learning disabilities (LDs) who were integrated full time in third grade team approach to mastery (TAM) classrooms were examined. Children with LDs, particularly boys, were well-integrated socially in TAM classes. The mixture of students may enhance acceptance of children with LDs.…

Academic self-concept, academic locus of control, and achievement expectations were investigated over a two-year period for 78 children identified as learning disabled (LD) and 71 normal children. It appears that negative school-related attitudes develop early in LD children and remain consistent through high school. (TJH)

Fifteen learning-disabled (LD), 33 attention disordered (AD), and 28 normal adolescents were assessed with 2 performance measures and 3 behavioral measures while working on mathematics problems. Findings support theoretical predictions that LD and AD children have difficulty with repetitive stimuli, contributing to mathematics deficits. (SLD)

To determine whether disabled readers can benefit from letter-sound instruction if attention to individual regular words is increased, 38 male and 16 female disabled readers aged 7 to 13 years participated in whole word, letter-sound, or control training programs. Implications of improvement by both experimental groups are discussed. (SLD)
