The main purpose of this study was to investigate whether different attentional operations at
encoding stage affect perceptual priming. In experiment 1, 60 college students were studied on perceptual
recognition under different levels of attentional manipulation, and it was found that there were significant
differences in response under three levels of attentional manipulation. In experiment 2, 40 college
students were studied on perceptual recognition under different numbers of attention objects, and it was
found that there were significant differences in response under two different numbers of attention objects.
The results showed that the priming effect was reduced when distractors were identified and responded
frequently in the coding stage. When the distractor and the target stimulus were on the same attentional
object, the priming effect was further reduced when the distractor and the target stimulus were on
different attentional object.
