不同背景下逆显的突显工效研究

Study on the Highlighting Effect of Reverse Video in Different Background

实验对黑、白背景下逆显的突显工效进行考察。结果表明 :( 1)逆显作为突显类型不会提高被试的搜索绩效 ,反而会明显降低被试的视觉搜索的绩效。 ( 2 )不同背景条件下 ,逆显突显都会降低视觉作业的绩效 ,但采用白背景时 ,这种负效应并不明显。 ( 3 )在逆显突显条件下 ,不同视觉背景对被试绩效的影响非常明显 。

The effects of reverse video as type of highlighting on visual search performance in white and black background were investigated. The results show that: (1) There were negative effects of reverse video on visual search performance in both backgrounds.(2)The visual search performance is lowered by reverse video in all types of background,although the negative effect is not significant in white background.(3)There are obvious influence of background types on visual search performance in reverse vides condition, and the white background is conductive to improve the visual search performance.
