This study investigates whether words differing in a single contrastive semantic feature (positive/negative) can be discriminated by auditory evoked responses (AERs). Ten right-handed college students were provided with auditory stimuli consisting of 20 relational words (more/less; high/low, etc.) spoken with a middle American accent and computer…

Author studied the capacity of the normal brain to carry out a paired-associate learning task by projecting the stimulus material to either the right or left hemisphere in order to establish if there was a lateral specialization for this type of learning in the normal brain. (Author/RK)

This study measured test-retest reliabilities and interrelationships of four common measures of lateral dominance: dowel balancing, peg placement, grip strength, and conjugate lateral eye movement. Moderate reliabilities for all measures except grip strength were obtained. Subjects' sex may be an important reliability variable. Correlations among…

The fact that there is an imperfect correlation between the asymmetrical function of the two halves of the brain and handedness has been a source of puzzlement for many investigators. Many theories have been proposed to explain handedness and why handedness does not correlate perfectly with other measures of lateralization. To assess the…

The sighting dominance and acuity of second-, fourth-, and seventh-grade children, and of college students were measured. Results showed a right versus left sighting dominance occurring in a ratio of 2:1 at each age. Patterns of acuity dominance also remained constant across grades. (Author/JMB)

In an attempt to replicate the finds of Sackeim, Paulhus, and Weiman (1979), three classrooms of college students were tested for hypnotic susceptibility, handedness, and seating preferences. No relationships between variables were found for males. For females, relationships were inconsistent. Relationships between hypnotic susceptibility and…

Two enduring questions in psychology concern the effects on behavior of traits and of attitudes. One method of altering the relative influence of traits or attitudes is by manipulating the activity of those areas of the brain which attend more to the self or to the external environment. Two experiments were conducted to test whether manipulation…

Investigates the different levels in the visual system at which laterality effects may be elicited in children and adults in five different experiments. (LLK)

Group and individually administered measure of intelligence were related to laboratory based measures of human information processing on a group of college freshmen. Among other results, high IQ was related to right hemisphere efficiency in processing non-linguistic stimuli. (Author/JKS)

The relationships among preferred handedness, family history of sinistrality, sex of subject, and spatial visualization were examined in college students. Males outperformed females at all levels of handedness when measured as a continuous variable. Extreme handedness was associated with poorest performance. Decreased hemispheric specialization…

The purpose of this study was to examine whether people who differ in behavioral and self-report measures of lateralized seating preferences also differ in hypnotic susceptibility. Only right-handed subjects were used, and the associations between hypnotic susceptibility and seating preference were examined separately for males and females.…

A brain laterality test and a creativity test were administered to 119 economics and accounting students and 65 creative arts students. No differences were found between the two types of students in brain dominance or creativity. Students who displayed right hemispheric superiority also excelled on the creativity tests. (JDD)
