Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)

Tested children with apparatus that dropped balls through clear or opaque interwoven tubes. Found that older children could solve configurations with greater number of tubes than younger children. Success with clear tubes did not transfer to opaque tubes. Significantly, errors were consistently directed to location directly below ball's last seen…

Describes the biological basis of learning and individuality. Presents an overview of recent discoveries that suggest learning engages a simple set of rules that modify the strength of connection between neurons in the brain. The changes are cited as playing an important role in making each individual unique. (MCO)

This article presents a rationale for emphasizing discovery instruction over guided instruction in teaching cane travel skills to people with severe visual impairments. Discovery instruction is seen to facilitate the use of intrinsic feedback in developing perceptual-cognitive skills as well as promoting problem solving, retention, and transfer of…

Suggests that individual differences in visual imagery and failure to realize their existence may have affected theories of thought throughout history. Offers possible explanations for the failure to validate thinking style differences in educationally significant ways. Argues that increased understanding of mental imagery can improve teaching.…

Early-, middle-, and late-phase client emotional arousal, perceptual processing strategies, and working alliance were examined in relation to treatment outcome on 4 measures in 32 clients who previously underwent experiential therapy for depression. Hierarchical regression analyses relating these variables to outcome indicated that results varied…

Verbal-to-spatial associations in working memory may index a core capacity for abstract information limited in the amount concurrently retained. However, what look like associative, abstract representations could instead reflect verbal and spatial codes held separately and then used in parallel. We investigated this issue in two experiments on…

Unrealistic personal optimism is the perception that undesirable events are less likely and desirable events are more likely to happen to oneself than they are to happen to other similar people. Three experiments were performed to study the relationships among personal optimism, perceived control, and selective activation of the cerebral…

Witkin's Embedded Figures Test (EFT) was used to measure the changes with age in field dependence and problem-solving ability. Qualitative data concerning problem-solving strategies and quantitative data were collected. EFT was administered to 12 females in each of the following decades: 20s, 30s, 40s, 50s, 60s, 70s. All subjects were moderately…

To determine the developmental level at which letter processing skills become automatic, an experiment was conducted using a variant of the visual search task. Subjects in grades one, two, and three and in college searched for target letters displayed on a cathode ray tube along with either visually confusable letters, acoustically confusable…

Morse code signals were presented dichotically to Morse code operators and to naive subjects with no knowledge of Morse code. The operators showed right ear superiority, indicating left hemisphere dominance for the perception of dichotically presented Morse code letters. Naive subjects showed the same right ear superiority when presented with a…

The perceptual-developmental research of Kagan and Witkin elicited this study of cognitive style. The work of these two researchers leads to the conclusion that differences between graphic expressions of children of the same age reflect differences in the children's mode of information processing. Specifically, this study sought to test the…

Students in grades K, 1, 3, and 5 were administered the Rod and Frame Test (RFT), the Matching Familiar Figures (MFF) Test, and the Piagetian tasks of Discontinuous Quantity, Class Inclusion, Multiplication of Classes, and Multiplication of Relations. Cross-sectional trends were found in all tasks with older children being less impulsive, more…

Two techniques were used to modify an impulsive conceptual tempo on a visual discrimination task. The subjects were 42 first grade white children who had previously been classified as impulsive or near-impulsive on the Matching Familiar Figures Test given to 82 children. These subjects, who had scored above the median on errors and below the…

This curriculum guide for a high school junior- and senior-level English program identifies twenty-two characteristics of a successful graduate. These characteristics are regarded as goals to be met through the completion of units on four communicative processes: (1) reading, (2) writing, (3) speaking and listening, and (4) thinking and…
