The influence of temporal association on the representation and recognition
of objects was investigated. Observers were shown sequences of novel faces
in which the identity of the face changed as the head rotated. As a result
, observers showed a tendency to treat the views as if they were of the sam
e person. Additional experiments revealed that this was only true if the tr
aining sequences depicted head rotations rather than jumbled views: in othe
r words, the sequence had to be spatially as well as temporally smooth. Res
ults suggest that we are continuously associating views of objects to suppo
rt later recognition, and that we do so not only on the basis of the physic
al similarity, but also the correlated appearance in time of the objects.
