The Effect of Time Factor on Object Feature Binding under the Masking Condition
Using the cueing paradigm,this study investigated the effect of time factors on object feature binding under the masking con-dition.Experiment 1 mainly examined the effect of the presentation time of recognition items on object feature binding,and Experiment 2 mainly focused the effect of the time interval(ISI)between memorization items and masking stimuli on object feature binding.The ex-perimental results showed that:(1)The recall performance of object working memory significantly improved with an increase in the pres-entation time of memorization items,under the conditions of both without mask and masking stimuli uncovering the target item.Howev-er,when masks covered the target item,there was no difference in performance across the three presentation time conditions.(2)The re-call performance with masking stimuli was worse than that without masking,and it was the lowest when masking stimuli covered the tar-get item.(3)The performance decreased significantly with the increase of ISI.(4)The interaction between ISI and masking type is sig-nificant,and compared with other conditions,when mask stimulus appeared at the target item location after the memorization item disap-peared for 250 ms,participants'recall performance was the lowest.These results indicate that mask stimulus needs to appear at the tar-get location before the completion of visual working memory consolidation,so that it can substantively interfere with the object's feature binding.It is also proved that the information consolidation of visual working memory is a relatively independent process with a duration of at least 250 ms.
