Comparison of cognitive performance of 51 students with hearing loss and 64 hearing students indicated that, at age 10, students with hearing loss performed better on nonverbal tasks and worse on verbal tasks. At age 13, students with hearing loss performed poorly in both verbal and nonverbal tasks. (Author/SW)

This study used a well-normed task of face recognition with 102 young children with autism, pervasive developmental disorder (PDD) not otherwise specified, and non-PDD disorders (mental retardation and language disorders) matched for chronological age and either verbal or nonverbal mental age. Autistic subjects exhibited pronounced deficits in…

There is some consensus in the literature regarding the cognitive profile of people with Asperger syndrome (AS). Findings to date suggest that a proportion of people with AS have higher verbal than performance IQ, a non-verbal learning disability (NVLD) and impairments in some aspects of executive function (EF). However, there are few published…

Pavlovian stimuli can markedly elevate instrumental responding, an effect known as Pavlovian-instrumental transfer (PIT). As the role of the ventral tegmental area (VTA) in PIT is yet unknown, we examined the effects of transient VTA inactivation by direct microinjections of a mixture of the GABA[subscript A] and GABA[subscript B] receptor…

The ability to detect and learn about the predictive relations existing between events in the world is essential for adaptive behavior. It allows us to use past events to predict the future and to adjust our behavior accordingly. Pavlovian fear conditioning allows anticipation of sources of danger in the environment. It guides attention away from…

Sociolinguistic data regarding code selection and nonverbal modes of learning are examined in the gesture communication system of the (Oglala and Brule) Sioux. Sign language is viewed as an extra-linguistic mode of communication currently in use in Indian classrooms. It is one alternative to literacy as a means of communication; however, this is…

Investigated with 58 gifted children (in grades 5 or 6) were differences in right and left hemispheric brain functions in the context of J. Piaget's theories of stages of cognitive development. (DB)

Reports on a research study which compared children's verbal and nonverbal responses to music stimuli. Also examines the relationship between verbal and visual responses. Concludes that educators should continue to search for efficient sequencing of associative pairings of oral/visual stimuli in order to make traditional music terminology more…

Infants ranging in age from six months to eight months were shown repeated instances of real object movement-disappearance-reappearance. Results suggest that the key changes in early cognitive development rest primarily upon the infant's gradual adaptation of old responses through encounters with new events--rather than upon the acquisition of…

A teacher relates the experiences he and his classes had as a result of nonverbal instruction in mathematics. He tapped creative resources within himself of which he was previously unaware and his students became more involved in formulating the rationales of the mathematics being taught. (JP)

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)
