The author presents experiemental evidence that visual coding is a significant factor in human memory, and examines evidence for the trace modality theory which states that recognition can only be mediated via the modality in which original material was encoded. (GW)

Language is shown to be an inappropriate tool for developing a child's mind, based on a Piaget-derived theory of intelligence in which thinking is not primarily language-based. Implications for teachers of normal and deaf students in terms of classroom activities to develop students' thought processes are considered. (KW)

Tests the developmental memory lag hypothesis with 22 learning disabled boys on two- and three-dimensional nonverbal tasks. Finds age-equivalent recall patterns similar to those of normal children and consistent age-related differences in nonverbal recall, thereby negating the developmental lag hypothesis. (RL)

The follow-up study of 16 nonretarded autistic children as adults found that, though most were functioning poorly in terms of occupational-social outcome and psychiatric symptoms, four had essentially recovered. Severity of early autistic behavior was a poor predictor of outcome, but neuropsychologic measures of nonverbal problem solving were…

Describes two experiments which examined how supplementing specific practice experiences with variable practice experiences influenced motor skill retention. Participants received varying trials of acquisition practice on a criterion force production task. Acquisition practice with variations of the criterion task led to better retention than…

A six-year-old nonvocal girl with autism who had acquired a variety of signs and imitative responses consistently failed to acquire a tact (labeling) repertoire. When procedures to transfer stimulus control from verbal to nonverbal stimuli were implemented, the subject quickly learned to tact all 18 target stimuli. (Author/DB)

This study investigated conditions for optimizing college students' analogical problem solving. Students given pictorial (not verbal) representations of solutions to source problems were better problem solvers, as were students given a longer time. Students who derived personal solution principles to source problems were not superior to students…

In the present study the neuropsychological, academic and social-emotional profiles were examined in Neurofibromatosis type 1 (NF1) children. Subjects: 17 NF1 children (ages 7-11) with NF1 without serious medical problems and with a full scale IQ (FSIQ) above 70. Wechsler Intelligence Scale for Children-Revised (WISC-R), academic tests and an…

A common cellular alteration, reduced post-burst afterhyperpolarization (AHP) in CA1 neurons, is associated with acquisition of the hippocampus-dependent tasks trace eyeblink conditioning and the Morris water maze. As a similar increase in excitability is correlated with these two learning paradigms, we sought to determine the interactive…

Composition researchers and teachers grant that the relationship of non-verbal thinking and language plays a crucial role in the writing of fiction and poetry, but they are sometimes reluctant to perceive that non-verbal thinking must, necessarily, be crucial, with different emphases, in the thinking/writing processes of rhetoric. Activities and…

The theoretical orientation based on perceptual development, proposed by Piaget in 1961, is the starting point of this investigation. According to Piaget, the perception of the young child is "centered" on dominant aspects of the field. With maturity, perception becomes "decentered" and progressively freed from the field. The…

Unfortunately, the current popularity of questioning strategies has led to their widespread excessive and/or exclusive employment in evaluating reading comprehension. An approach in reading instruction which utilizes both verbal and nonverbal communication for assessing comprehension contains several unique features that provide for the…

Several theories in audiovisual education hold that learning from a visual illustration is directly related to the realism of the visual aid. In order to test this theory, five treatment groups were established. All groups were pretested, taught the same unit of instruction, and posttested. Four groups saw slide sequences in which were viewed…
