Abstract

This study proposes that the lexical-semantic capacities of the right hemisphere (RH) are underestimated in normal subjects and reexamines them in a "dynamic model" framework. As expected, overloading the left hemisphere by combining a lexical-decision task presented in divided visual field with a concurrent heavy verbal memory load, and activating the RH by combining thelexical-decision task with a concurrent visuo-imaged memory load, lead to enhanced left visual field-RH lexical performance. The RH appears to support a larger lexical-semantic network than suggested in the literature, including representations for long and nonimageable words, and the accessibilitythreshold for the representations stored therein is modulated by hemispheric activation-inhibition mechanisms.
