RESUMO
The authors tested functional hemispheric asymmetry through word dichotic listening and lateralized lexical decision tasks in tinnitus patients and controls stimulated by a continuous tinnitus-like noise to test the influence of a tinnitus-like external stimulation. A classic right-ear advantage was shown in the auditory task for all but right-ear tinnitus patients, who performed as equally badly when the stimuli were presented to the right and left ears. Concerning the visual task, all participants demonstrated the expected right visual field advantage for word stimuli. Moreover, those who submitted to external stimulation demonstrated normal asymmetric patterns. These data suggest a specific effect of tinnitus on central processing and provide evidence for a functional reorganization induced by this auditory phantom perception.

We examined older adults' self-regulation within the region of proximal learning (RPL) framework. Younger and older drivers completed four circuits of increasing difficulty in a driving simulator and were then given a limited amount of time to train for a test. Although older drivers chose to train on easier circuits than younger ones, both age groups focused on the easier circuits first, only moving to the more difficult ones later. They were thus equally able to identify their RPL. This framework appears to apply beyond the obvious scope of metamemory and provides a behavioral assessment of self-regulation in driving settings.
