Aims to obtain prevalence figures for left-handedness among 10-year-old Swedish children; to replicate some findings concerning Bishop's (1980) extended pathological left-handedness hypothesis; to evaluate the influence of factors such as the child's sex and reduced optimality in the pre-, peri-, and neonatal period; and to determine the…

Examined the relationship between brain-behavior and hypnotic susceptibility in 70 alcoholic patients, using the Stanford Hypnotic Susceptibility Scale and its Fromm-Weingarten modification. Results showed the two scales were interchangeable insofar as they measured the same ability, and indicated that hypnotic susceptibility is related to…

Reviews research on cerebral asymmetry in hearing persons, clinical studies on lateralization and sign language, and experimental research on cerebral asymmetry in deaf persons. (AM)

The author explores some of the implications of E. Rossi's hypothesis that "fine literature and poetry is essentially a form by which the words of the left hemisphere give voice to symbols and archetypal patterns of the right" (hemisphere). (Author/PHR)

This study attempted to gather baseline data on a randomly selected population of 353 kindergarten and first-grade children for consistency of response in hand dominance measures and eye dominance measures and for comparison by sex, race, maturity and socioeconomic status. (Author/SB)

This study, involving adults with and without mental retardation and mental age-matched children, employed a lateralized presentation of Stroop color words, neutral words, and the subject's first name. Individuals with mental retardation experienced difficulty in effortful processing (inhibiting the reading response on the Stroop trials) and in…

This study of 34 adults with Down's syndrome found that right-handed subjects exhibited no lateral advantage in dihaptic shape-matching, whereas left-handed subjects displayed an expected left-hand advantage. In a visual field dot enumeration task, both groups exhibited left-field superiority. Results indicate that subjects' atypical cerebral…

Twelve males (ages 8-12) with phonological dyslexia were compared to 12 age-matched good readers and 12 reading-matched students. Results showed that dyslexia is not related to incomplete lateralization or to a failure to inhibit verbal processing in the right hemisphere during reading and writing. (Author/JDD)

Notes that high-resolution magnetic resonance imaging allows in vivo quantification of the surface area of the cortex covering the planum temporale. Reviews the definition of planum asymmetry as it relates to structural accompaniments of disorders such as developmental dyslexia and to anatomic and functional lateralization. Finds support for the…

This study examined the right hemisphere contribution to the production of linguistic prosody where acoustic features of prosodic structures in different linguistic contexts were examined accompanied by perceptual judgements. When control and right hemisphere damaged (RHD) subjects were asked to produce lexical stress differences (Experiment 1),…

The present paper reviews directionality trends in the drawing of horizontally extended figures and specifically investigates the influence of reading and writing habits and of handedness on directionality in adults. (Author)

In the neurolinguistic approach to the study of the acquisition of reading and writing, language may be used to express thoughts and intellectual attitudes as well as emotions and emotional attitudes. Experimental studies and clinical data suggest that grammatical rules for spoken language predominantly rely on the left hemisphere of the brain,…

Numerous areas associated with brain dominance have been researched since Bogen and Sperry's work with split-brain patients in the 1960s, but only slight attention has been given to the connection between brain dominance and personality. No study appears in the literature seeking to understand optimal mental health as defined by Maslow's…

Cardiac response to stimulation of the left and right perioral region in infants was examined. Cardiac acceleration and ipsilateral head turning occurred more reliably to stimulation of the infant's right side than to stimulation of the left side. Results reflect a difference in sensitivity at the infant's two sides. (SDH)
