The present study was undertaken to ascertain the test-retest reliabilities of the Annett Hand Preference Questionnaire and the Edinburgh Handedeness Inventory and to determine the relationship between the two tests and to attempt some assessment of their relative practical values. (Author/RK)

Reviewed is research in the neurophysiology of cognitive functions as it related to dyslexia. (DB)

Two studies examined the relationship between cognitive style as determined by conjugate lateral eye-movements and the ability to recognize correct inferences and specific items from textual and pictorial displays. Subjects were given related sets of sentences and pictures followed by separate inference and recognition memory tests. Results of…

Research conducted by Tadanobu Tsunoda on auditory and visual sensation, designed to test and understand the functions of the cerebral hemispheres, is discussed. Tsunoda discovered that the Japanese responses to sounds by the left and the right sides of the brain are very different from the responses obtained from people from other countries. His…

This paper synthesizes the implications from hemispheric lateralization studies with the concerns and potentials of visual literacy. An overview of hemispheric lateralization research is provided, including summaries of four illustrative studies: Galin and Ornstein; Levy, Trevarthen, and Sperry; Zaidel; and Molfese. The appositional and holistic…

Two different experimental procedures were used to examine (a) information-processing differences between two groups of subjects (Cs versus Vs) identified by the form of their conditioned eyeblinks; (b) information-processing differences between the right and left cerebral hemispheres; and (c) parallels between hypothesized C-V differences and…

The experiments reported here investigate the effects of different kinds of set on hemisphere differences, and confirm that, in some conditions, the hemispheric asymmetry in a particular task may shift when cuing establishes an attentional set. (Author)

Reports two studies relating schizophrenia to functional brain asymmetry. The first study found support for the hypothesis of left hemisphere dysfunction in schizophrenia, occurring at a rather early stage of information processing; the second study, using eye directionality as a measure of hemispheric activation, found that schizophrenics…

Examines the effect of stressful and nonstressful experimental situations upon the processing capacity of each cerebral hemisphere, through observing the differential performance tasks presented to right and left visual half-fields (VHFs). Also examines attentional bias and lateral eye movements. (Author/RK)

The author, searching for possible neurological anomalies behind a learning disability, focuses on the theory that faulty lateralization is implicated in reading difficulties. (Author)

Left-hemisphere language specialization in right-handed children was tested in children previously classified as consistent or nonconsistent in their hand preference. Results showed that both male hand preference groups demonstrated asymmetric interference in dual task tapping performance. In contrast, only females associated with consistency in…

This paper examines the influence of Norman Geschwind's model of connectionism, in which complex functions are built up by connecting primary areas in the brain, and notes his studies of the effects of disconnection on dyslexic individuals. Connectionist-based behavioral studies are reviewed, focusing on intracortical association connections and…
