How do we recognize objects after spatial transformations? Recent neurocomputational models proposed that object recognition is based on coordinate transformations which align memory and stimulus representations. If the recognition of disoriented objects is achieved by adjusting a coordinate system (or reference frame) then recognition should be facilitated when the object is preceded by a different object in the same orientation. Two objects were presented in close temporal contiguity in brief masked displays, either in congruent or incongruent picture plane orientations. In two experiments, naming accuracy was higher for congruent orientations. The congruency effect was independent of superordinate category membership (Experiment 1), and was found for objects with different (horizontal or vertical) main axis of elongation (Experiment 2). The results indicate congruency effects for common familiar objects, even for dissimilar shapes. The findings are compatible with models in which object recognition is achi
eved by an adjustment of a perceptual coordinate system.
