It is common to see mirror errors in letters in early stages of reading due to the mirror-generalization process that allows a visual stimulus to be identified independently of its orientation. To avoid such errors, this process must be inhibited. A special case would be children with dyslexia since their difficulties with the alphabetic code may…

Linguistic category learning has been shown to be highly sensitive to linear order, and depending on the task, differentially sensitive to the information provided by preceding category markers ("premarkers," e.g., gendered articles) or succeeding category markers ("postmarkers," e.g., gendered suffixes). Given that numerous…

Children with developmental dyslexia (DD) may differ from typical readers in aspects other than reading. The notion of a general deficit in the ability to acquire and retain procedural ("how to") knowledge as long-term procedural memory has been proposed. Here, we compared the ability of elementary school children, with and without…

Early and intensive behavioral intervention (EIBI) is an approach to treating the behavioral deficits and excesses observed in children with autism spectrum disorders. The magnitude of improvement in the overall functioning of children receiving EIBI has stimulated additional research and widespread clinical dissemination through the publication…

On discrimination learning trials which allowed subjects to press an information key when in doubt, retarded children made significantly more presses than control groups. Results confirmed the hypothesis that retarded children would be more outerdirected than normal children in a situation in which distractibility could not play a role. (Author/GO)

Tests the effects of stimulus variability on overgeneralization and overdiscrimination errors in children and adults. The subjects (n=64), adults and five-, seven-, and nine-year-old children, participated in a visual discrimination task. (CM)

The two experiments investigated stimulus novelty which may affect reward and nonreward in a discrimination learning situation at different ages. The first experiment compared two types of "trial one" stimulus procedures on error tendencies following reward and nonreward. The two procedures differed with respect to novelty effects. One group was…

As a result of findings of a previous study, this study, which sought to program preschool subjects to wait one minute for reinforcement, used pause-building procedures before delay conditions were started. The children, 3- to 5-year-olds, were designated either Baseline (control) subjects (n=3) or Programmed (experimental) subjects (n=5). Though…

The study indicated that remediation of a broad spectrum lower level skill can enhance the ability of the learning disabled to perform academic tasks which incorporate that skill, even without specific remediation of the academic skills themselves. (SBH)

Processing requirements in letter discrimination for beginning readers with reflective-impulsive and field-dependent--field-independent learning styles were investigated. Results were interpreted in terms of feature analyses employed in letter identification and discrimination. (BJG)

Each of two experimenters taught one set of 32 prekindergarteners to discriminate four different letter combinations (R-P, Y-V, C-G, and K-X). Each set of children was randomly selected and assigned to two treatment conditions. The treatment consisted of three warm-up trials, 10 actual training trials, and four post-test trials on a…
