Visual field differences in fast perceptual priming of possible and impossible object decisions were investigated in a go/no‐go task. Each participant ( n = 74) was tested in two blocks of trials, each block containing 128 combinations of same‐field and cross‐field presentations of prime (blank) and target stimuli. The results indicate that fast perceptual priming of object decisions recruits processes that involve both cerebral hemispheres, independent of pre‐existing representation. The priming effect was larger for possible than for impossible objects, but fast perceptual priming of object‐decisions was demonstrated for both possible and impossible objects, in terms of both reaction times and accuracy. Left‐hemisphere specific priming for impossible stimuli may be due to a left hemisphere encoding advantage for impossible parts, consistent with a structural description account.
