Thesis (Ph.D.)--University of Kansas, 1987.

Normal, monolingual, right-handed male subjects were studied in attempts to establish generality of data on computer-summed, event-related potentials (ERPs). Twenty, adult, male subjects were randomly and equally assorted into four independent groups. The subjects learned an artificial miniature language under one of the four conditions: W-NR (word projected, no rule), W-R (word projected, rule), D-NR (drawing projected, no rule), and D-R (drawing projected and rule). Subjects yielded measures on (1) latencies of auditorily and visually evoked, event-related potentials (ERPs); (2) second-language learning; (3) affect, and (4) brain temperature. The ERP components, P300 and N400, were measured via leads on the scalp over the frontal lobe, Wernicke's area, the supramarginal gyrus, and the left anterior temporal area of the left hemisphere; leads were also attached to the homologous areas of the right hemisphere. Following measures of artificial language training, measures of learning were obtained in 16 test trials in which visual presentation of either drawings or words were correctly or incorrectly paired with words of the language to be learned--the second language. Brain temperatures (both hemispheres) and affect (by the Multiple Affect Adjective Check List) were measured before and after the ERP and learning measures (i.e., before and after the experiment). The primary findings were these: The only significant ERP main effect was a difference in means of P300 latencies between hemispheres, loci over the right hemisphere generally exhibiting slower responses to the evoking stimuli. Learning conditions per se were not a significant source of variation, but reliable changes in temperature were observed. Temperatures invariably increased after artificial language training, and ERP measures on the left hemisphere generally were higher. The finding of bilateral asymmetry of brain temperatures is novel, but its significance and whether it is characteristic of right-handed subjects are unknown. Differences of emotionality (hostility, anxiety, depression, and positive affect) were not associated with the learning conditions.Subjects--Topical Terms:
