Inhibition of semantic association: evidence from item method directed forgetting

Recently more and more evidence includes behavior and neuroscience studies support an active attentional inhibition process in item method directed forgetting. Lee & Lee (2013) discovered forget cue induced the “characters” of words were suppressed when participants have to name ink color of the to-be-forgotten (TBF) words. However, Lee (2009) used word-naming task and the result implied the suppress process in the meaning of word. The purpose of present experiments were to provide more evidence to support the suppress process in semantic level. In item method directed forgetting procedure, each study word was followed by an instruction to remember or forget. In present experiments participant was asked to think a related word and say it out when they saw study words. In the experiment 1, the study and the associative words both showed directed forgetting effect (participants recalled more TBR (to-be-remembered) than the TBF words, p = .001?p = .01 respectively). The percentage of recall of TBR and TBF study words were .46 and .31; TBR and TBF associative words were .32 and .22. However in experiment 2, the recognition task showed the forgetting effect disappear in both study words (TBR: .90; TBF: .88) and associative words (TBR: .80; TBF: .84). Although association processing produced a better memory in recognition task, but the directed forgetting effect in recall task indicated the forget cue has more power than memory association processing. More important the participants weren’t asked to remember or forget the associative words. The directed forgetting effect of associative words indicated TBF words also be suppressed due to their relation between study and associative words. Finally the suppression was released from recognition task.
