Recent work has found support for two dissociable
and parallel neural subsystems underlying object
and shape recognition in the visual domain: an abstractcategory
subsystem that operates more effectively in the
left cerebral hemisphere than in the right, and a specificexemplar
subsystem that operates more effectively in the
right hemisphere than in the left. Evidence of this asymmetry
has been observed for linguistic stimuli (words,
pseudoword forms) and nonlinguistic stimuli (objects). In
the auditory domain, we previously found hemispheric
asymmetries in priming effects using linguistic stimuli
(spoken words). In the present study, we conducted four
long-term repetition-priming experiments to investigate
whether such hemispheric asymmetries would be observed
for nonlinguistic auditory stimuli (environmental sounds)
as well. The results support the dissociable-subsystems
theory. Specificity effects were obtained when sounds were
presented to the left ear (right hemisphere), but not when
sounds were presented to the right ear (left hemisphere).
Theoretical implications are discussed. [-]
