Post Onset

This article presents retrospective longitudinal perceptual and acoustic analyses of the recovery of motor speech control in a right-handed 5-year-old male in the 46 weeks following acquired brain damage. The primary lesion site involved the left fronto-parietal cortex. Correlative descriptions of some aspects of linguistic recovery up to 29 months post-onset are also presented. A mute period of 8 days followed a 2-day comatose period. Spontaneous undifferentiated central vowel-like utterances emerged at 11 days post-injury. Intelligible purposeful utterances emerged at 26 weeks post-onset with the motor speech impairment resolving almost completely within the first year post-onset. The motor speech deficit following the mute period was more consistent with the diagnosis of apraxia of speech than dysarthria. Further, the seemingly lateralized damage associated with the communication disorder may indicate that lateralized hemispheric control of motor speech occurs in early childhood. Finally, the redevelopment of motor speech abilities indicates that the young child’s brain is able to reestablish parameters of motor control underlying speech following acquired brain damage.

Perceived Duration

20 right-handed males judged the duration of small and large colored circles, which were briefly exposed in the left, center, and right visual fields. Perceived duration was a logarithmic function of exposure duration and a positive function of size and chromaticity. Over-all accuracy was equivalent in the left and right visual fields, but the effects of chromaticity and duration on subjects' judgments were asymmetrical. These and other findings suggest a two-process model of time perception in which there is right hemispheric control over a visual information processor and left hemispheric control over a timer.

Hemispheric Control

Abstract Based on data from an earlier study (Lambert 1993), and on a propositional approach developed by Lemieux (1995), who refined quality of interpretation measurements sufficiently to determine a right-ear superiority at the beginning of a message and a left-ear superiority at the end of a message, the present study went one step further to examine the role played by experience, age and age of bilinguality, all possible factors influencing the hemispheric control of interpretation. Results indicated that the number of years of experience influences the quality of interpretation in that the more experienced interpreters interpreted better, regardless of ear of input. But overall results point to the possibility that hemispheric preferences for linguistic analysis might be much more under an interpreter’s voluntary control than first anticipated.
