There is considerable evidence that encoding and consolidation of memory are modulated by emotion, but the retrieval of emotional memories is not well characterized. Here we manipulated the emotional context with which affectively neutral stimuli were associated during encoding, allowing us to examine neural activity associated with retrieval of…

A study involved the development and testing of a theoretical framework of cerebral specialization in which each hemisphere of the brain is viewed as an independent information processing system. During the study, four sets of experiments were conducted. These involved behavioral as well as electrophysiological measures. According to the…

In an investigation using auditory evoked responses (AERs) to compare strongly left- and strongly right-handed adults in their hemispheric processing of speech materials, it was anticipated that AERs would reflect a bilateralization in the left-handed group of subjects and marked hemispheric differences in the right-handed group. In addition, the…

Recent research in adult pronunciation of foreign languages has assigned a significant role to affective variables. It has been shown that certain language functions, including many aspects of pronunciation, are handled by the right brain hemisphere. An experiment was conducted to study the extent to which the right hemisphere might be activated…

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…

Twenty-nine male and 35 female right-handed children, aged five to seven, were assessed for the effect of familial sinistrality left-handedness on a rapid color-naming task. Controlling for age and family size, a significant effect for degree of familial sinistrality was found in the girls but not in the boys. (Author)

Examined consistency of hand preference in a longitudinal study of children between 18 and 42 months of age. Results showed a sex-specific relationship between hand consistence and intellectual development. Females with consistency of handedness were precocious compared to females without such consistency; the same relationship did not hold for…

In assessing reflective gaze preference, students were assigned to right-looking, left-looking, or mixed groups. Those with more clearcut preferences were shown to have superior records of athletic achievement, consistent with the model of functional cerebral space which predicts superior simultaneous task performance for more cerebrally…

Five theories were tested relating to the suspected connection between organic brain dysfunction and poor reading, or dyslexia. Results failed to support the poor lateralization, right hemisphere, global, imbalance theories. Among juvenile offenders, poor reading appears to relate to left-hemisphere dysfunction. (Author)

Naval recruits attending a remedial reading program were compared to regular recruits on verbal, nonverbal, demographic, and eye-hand laterality measures. Verbal intelligence scores on the General Classification Test differentiated best between the two groups. Findings on race and laterality factors are also discussed. (Author/SJL)

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…

Presents evidence of differences in brain function lateralization between Japanese-speakers and speakers of Indo-European languages, and suggests that current conceptualizations of brain function specialization are not adequate. (AM)

Twenty-eight L-dyslexic and 26 P-dyslexic children (mean age of 9-10) received hemisphere-specific stimulation (HSS) by presentation of words to right and left fingers, respectively. Relative to controls, HSS-treated L-dyslexic subjects showed larger improvement of accuracy in text reading, whereas HSS-treated P-dyslexic subjects showed more…

Evaluates a substantially updated version of the "classical" idea of a significant relationship in dyslexic children between cerebral lateralization and their word decoding deficits. Finds further evidence that dyslexia is not related to incomplete lateralization. Suggests that dyslexics suffer from exuberant right hemisphere processing in…

A study of 12 patients with left-hemisphere damage (LHD) and aphasia, 10 with right-hemisphere damage (RHD), and 10 controls, sought to identify phonemic and emphatic stress contrasts. Individuals with LHD were unable to identify phonemic stress contrasts with better-than-chance accuracy. Individuals with RHD performed better than those with LHD.…
