Dissociating Simon and affordance compatibility effects: silhouettes and photographs.

When a graspable object's handle is oriented to the same side as the response hand, responses are quicker and more accurate than when it is oriented to the opposite side. This effect has been attributed to the affordance of the object's handle (Tucker & Ellis, 1998). Recent findings suggest this effect results instead from an abstract spatial response code (i.

Implicit contributions of context to recognition.

Studies of the impact of context on remembering have not focused on the influence of contextual contingency on subsequent recognition in the condition in which the contingency cannot be verbalized. In two experiments, we analyzed the effect of an implicitly encoded position contingency involving location and semantic category on both hit and false alarm recognition judgments after 1 day and 1 week delays. We vigorously probed for what participants could say about the contingency.

What we see: inattention and the capture of attention by meaning.

Attention is necessary for the conscious perception of any object. Objects not attended to are not seen. What is it that captures attention when we are engaged in some attention-absorbing task? Earlier research has shown that there are only a very few stimuli which have this power and therefore are reliably detected under these conditions (for example, Mack & Rock, 1998; Moray, 1959).
