ABSTRACT
Objective To explore the influence of visual working memory contents on visual func-tion and fluid intelligence.Methods 42 subjects were randomly divided into three groups:controll group in-cluding 17 people who had no training,working memory based on Gabor vision group including 13 people and standard working memory group including 12 people who received the N-back working memory training for 15 days,and lasted half an hour in every day.The contrast sensitivity was recorded and measured using OPTEC6500,and the fluid intelligence was measured with the Raven's advanced progressive matrices before and after training.Results In the Gabor working memory group,there were salient gains in contrast sensitivi-ty(respectively(1.48±0.26)log,(1.87±0.13)log,P＜0.05)and in fluid intelligence(respectively(11.15± 1.28),(13.46±1.76),P＜0.05)between pre-and post-test. In the standard working memory group,the con-trast sensitivity improvement was not significant(respectively(1.72±0.30)log,(1.75±0.31)log,P＞0.05),the fluid intelligence increased significantly(respectively(11.25±1.91),(13.00±1.86),P＜0.05); while the controlling group had no significant difference in contrast sensitivity (respectively(1.61±0.26)log,(1.67± 0.25)log,P＞0.05)and in fluid intelligence(respectively(11.41±1.87),(11.58±1.94),P＞0.05) between pre-and post-test.Conclusion Working memory training based on Gabor vision can enhance the subjective perception of visual stimuli and improve the behavioral effect of visual contrast sensitivity, but the visual working memory contents do not affect the migration effect of working memory training on fluid intelligence.
