短期学习对陌生面孔认知绩效的影响

The Effects of Different Exposure Time on Unfamiliar Face Recognition

本文研究了不同的短期学习时间对陌生面孔的绝对辩认绩效的影响。结果表明 :(1 ) 0 5分、1分、5分这三种不同的短期学习时间对陌生面孔的绝对辩认绩效没有明显的影响。 (2 )人们对人脸结构信息的改变非常敏感 ,当结构信息变动 4 88个象素 (或 9 1 3’)时 ,被试对陌生面孔的平均正确绝对辩认率可达到 75 %以上。 (3)在对陌生人脸的绝对辩认中 ,被试的正确辩认率随着结构信息变化量的增加而提高 。

This paper studied the effects of different exposure time on unfamiliar face recognition through memory tasks.The results showed (1)three exposure conditions,including 0.5 minute,1 minute,5 minutes,had no significant effect on performance in recognizing unfamiliar faces.(2)the subjects were sensitive to the change of configural information,and the accuracy rate was beyond 75% when the eye moved inward or outward 4.88 pixels.(3)the accuracy rate increased with the amount of configural information
