The primary question this research addressed was whether it was possible to detect independent influences of IC and WM processes on the decline in the age-related executive control of eye gaze. A significant interaction was observed between age group and the AST-go/no-go latencies. The AST-go/no-go demands a greater IC than the standard AST; the substantive effects in the older cohort provide strong evidence that it is the increased inhibitory load (rather than WM) that was problematic for this older group. This finding supports the Hasher and Zacks (1988) Inhibition Hypothesis. However, AST errors were increased in all of the ASTs. This suggests that, for the older group, neither the selective facilitation of WM nor IC was sufficient to eliminate AST errors. Apparently, both of these operations contribute to the errors that older people experience in the ASTs. The error data demonstrates that healthy aging is associated with changes in both IC and WM. Reduced IC was related to the slowing in the speed of reaction times in the older groups, while reduced WM and IC both contribute to the increased errors.
