Bs. Gibson et Ma. Peterson, DOES ORIENTATION-INDEPENDENT OBJECT RECOGNITION PRECEDE ORIENTATION-DEPENDENT RECOGNITION - EVIDENCE FROM A CUEING PARADIGM, Journal of experimental psychology. Human perception and performance, 20(2), 1994, pp. 299-316
Object recognition may entail an incremental normalization process bef
ore access to canonical orientation representations, but is this proce
ss guided by prior access to object-centered representations? In Exper
iment 1, the authors showed observers figure-ground stimuli known to r
eflect access to, and output from, stored shape representations. The s
timuli appeared in each of 6 different orientations, preceded by cues
providing either (a) no information, (b) upright shape information onl
y, (c) upright shape information plus orientation information (separat
ely), or (d) shape information in the same orientation as the upcoming
figure-ground test stimulus. Contrary to predictions by a postaccess
account, the cues failed to eliminate orientation dependency in shape
recognition. The results favor a preaccess account of the normalizatio
n process within the context of canonical orientation representations.
