| Research Abstract |
In a series of experiments, our participants imitated two video-presented actions either in the order presented or in reversed order, performing the actions in time with tones. This technique produced action spoonerisms and other types of action slip. The former increased equally when articulatory suppression and body movement suppression were performed concurrently, but the latter increased more under the movement suppression condition than under the articulatory suppression and silent control conditions. Furthermore, when conflict regarding the sequence of the two actions was minimized, the effect of articulatory suppression on the frequency of action spoonerisms decreased. The data suggested that articulatory suppression can induce action slips by weakening action binding under conflict regarding action sequences.
