Changing internal constraints on action: the role of backward inhibition.

摘要: Flexible control of action requires the ability to disengage from previous goals or task sets. The authors tested hypothesis that disengagement during intentional shifts between sets is accompanied by inhibition set ("backward inhibition"). As an expression backward predicted increased response times when shifting a had be abandoned recently and, thus, suffers residual inhibition. critical effect on level abstractly defined perceptual was obtained across 6 different experiments. In addition, it shown can differentiated negative priming (Experiment 2), tied top-down sequential 3), account at least partially for "residual shift costs" in set-shifting experiments 4), and occurs even context preplanned sequences 5).
