“…Further, at ISIs of up to 0.5 sec, but less than 2 sec, there was a further decrease in decision time if the two pictures were physically identical. This latter view-specific benefit was eliminated if a collage of photo fragments was presented in the interval between the two pictures (see also Marshall & Walker, 1987). These data fulfil Posner's (1978) criterion for distinguishing internal codes.…”

Three experiments are described in which two pictures of isolated man-made objects were presented in succession. The subjects' task was to decide, as rapidly as possible, whether the two pictured objects had the same name. With a stimulus-onset asynchrony (SOA) of above 200 msec two types of facilitation were observed: (1) the response latency was reduced if the pictures showed the same object, even though seen from different viewpoints (object benefit); (2) decision time was reduced further if the pictures showed the same object from the same angle of view (viewpoint benefit). These facilitation effects were not affected by projecting the pictures to different retinal locations. Significant benefits of both types were also obtained when the projected images differed in size. However, in these circumstances there was a small but significant performance decrement in matching two similar views of a single object, but not if the views were different. Conversely, the object benefit, but not the viewpoint benefit, was reduced when the SOA was only 100 msec. The data suggest the existence of (at least) two different visual codes, one non-retinotopic but viewer-centred, the other object-centred.

“…Marshall and Walker (1987), Roberts and Bruce (1989), and Verfaillie (1993) all report that same-orientation priming is greater than different-orientation priming following depth rotation. This suggests that short-term priming might also be sensitive to plane rotation, at least when subjects are unpracticed with the stimuli.…”

In naming drawings of complex common objects, unpracticed naming times increase with rotation away from the upright, but this orientation effect is attenuated with practice. In principle, attenuation could result from learning to extract orientation-invariant information or from learning view-specific representations at the trained orientations. We contrasted these approaches by examining repetition priming for prime-target pairs presented on successive trials in either the same orientation (horse at 51°primes horse at 510) or a different orientation (horse at 154°primes horse at 510), for two subgroups of subjects. One subgroup showed no orientation effect, even when unpracticed, and a correspondingly high generalization of priming across different views. The other subgroup initiallyshowed high sensitivity to misorientation and little priming across orientations but, with sufficient practice, came to show no orientation effect and complete generalization of priming. Thus, some subjects always used orientationinvariant procedures, whereas others learned to do so.

“…Fourth, in serial-choice reaction time tasks, response times (RTs) were shorter when the object in a primed trial had the same orientation as the object in the immediately preceding, priming trial (e.g. Marshall & Walker, 1987). Finally, Srinivas found more long-term priming in an object/non-object decision task when the objects were primed with the same view than when they were primed with a view that differed more than 67° (Srinivas, 1995).…”

Viewpoint-dependent Priming Effects in the Perception of Human Actions and Body Postures

The identification of human actions and body postures viewed from different viewpoints was examined in four long-term priming experiments with static pictures of a human model. In Experiments 1 and 2 participants had to name or describe the pictures, and in Experiments 3 and 4 participants had to decide whether the pictures showed a possible or impossible body pose. Reliable priming effects were obtained only when priming and primed action or pose shared the same in-depth orientation (Experiments 1 and 4) and left-right reflection (Experiments 2 and 3). Having seen the same action or pose in a different orientation did not reliably facilitate identification performance later on. Also, there was no priming for poses that are impossible to perform with a human body, not even when an identical same-view prime was used. These findings suggest that the stored representations that mediate the identification of human actions and postures are viewpoint specific.One kind of stimulus that virtually all human observers encounter numerous times in their lives is other human beings, engaged in many different actions, resulting in an even greater variety of body postures. Identifying these actions and body postures must therefore be a major task of the human visual system. This task is not straightforward, though. Depending on the orientation and position of the acting body relative to the observer, different instances of a Requests for reprints should be addressed to A. Daems,
