Ideomotor compatibility enables automatic response selection

Running head: IDEOMOTOR COMPATIBILITY

For 30 years, Greenwald and Shulman’s (1973) psychological refractory period (PRP) study has been cited as evidence for perfect timesharing with two ideomotor (IM) compatible tasks. Recently, Lien, Proctor, and Allen (2002) failed to replicate their results and concluded that the use of two IM compatible tasks is neither necessary nor sufficient to eliminate the PRP effect. Greenwald (2003) sug...

Dissociating Ideomotor and Spatial Compatibility: Empirical Evidence and Connectionist Models

The tendency to imitate others is a fundamental social skill which could develop via associative learning or some more specialized mechanism, such as observation-execution matching. In this paper, we employ a stimulus-response compatibility paradigm to evaluate whether ideomotor compatibility conforms to the same processes as other S-R responses. The findings reveal a dissociation between spati...

Choice and stimulus-response compatibility affect duration of response selection.

In general, for movements to visual targets, response times increase with the number of possible response choices. However, this rule only seems to hold when an incompatibility exists between the stimulus and response, and is absent when stimulus and response are highly compatible (e.g., when reaching toward the location of the stimulus). Stimulus-response (S-R) compatibility can be manipulated...

Is automatic imitation a specialized form of stimulus- response compatibility: dissociating imitative and spatial compatibility

In recent years research on automatic imitation has received considerable attention because it represents an experimental platform for investigating a number of inter-related theories suggesting that the perception of action automatically activates corresponding motor programs. A key debate within this research centers on whether automatic imitation is any different than other long-term S-R ass...
