摘要
本实验对黑、白背景下高频、中频、低频三种闪烁的突显工效进行了比较研究。实验结果表明:闪烁作为突显类型可以提高视觉搜索的绩效,而且,在闪烁的频率较高时(27Hz以上),这种闪烁的突显工效更为明显。视觉材料的呈现背景对闪烁突显视觉搜索绩效没有明显的影响,但在白背景下采用闪烁效果较好。
The effects of blinking as a type of highlighting on visual search performance in white and black backgrounds were investigated. The independent variables included three blinking conditions: 3 Hz, 27 Hi and 81 Hz, and white and black visual backgrounds. The results showed that effects of blinking on visual search Performance were found in both backgrounds, especially when the blinking frequency were 27 Hz or 81 Hz.
