项目摘要

We have performed following four experiments.1) Simple reaction time to color stimulus.We measured simple reaction time (RT) to different hue, saturation or brightness in healthy undergraduate students. RT was faster to red and green, and was slowest to blue. Saturation had no effects on reaction time. Color preference, scored by using SD method, was highest to blue and lowest to yellow, thus no significant correlation between the preference and RT was observed. These data suggest that hue of color is important factor to arousal and emotion.2) Color memory.We investigated difference in memory to color stimuli with different hue using a sample-to-matching task in undergraduate students. Under photopic condition, a sample stimulus was presented on CRT followed by a matching stimulus with a delay of 3 sec. Subjects were asked to identify the sample stimulus from the two matching stimuli. Percent correct response was highest in green and lowest in blue. On the contrary, discrimination score was lowest in green and highest in blue. These data show that hue effects significantly to the working memory of color.3) Photic driving in Pokemon patients.EEG were recorded from patients, who suffered from watching to Pokemon-film on TV. Repetitive flash of lights were delivered with a frequency of 3-20 Hz. An induction phenomenon of alpha-wave was significantly different from those in normal controls.4) Prepulse inhibition to color stimuli.Color prepulse effects on startle eye blink reflex were examined in 15 subjects with a leading time of 100 ms. Amplitude of the blink reflex to sudden air puff to the cornea was significantly suppressed by a preceding presentation of color stimulus. Yellow was most effective in suppression. Thus, we conclude that yellow is most effective in inhibition of emotional and startle response.

本研究进行了以下四个实验：1）对颜色刺激的简单反应时：测量了健康大学生对不同色调、饱和度和亮度的简单反应时。RT对红色和绿色的反应更快，对蓝色的反应最慢。饱和度对反应时间没有影响。用SD法对颜色偏好进行评分，结果显示，对蓝色的偏好最高，对黄色的偏好最低，因此，RT与颜色偏好之间没有显著相关性。这些数据表明，颜色的色调是影响唤醒和情绪的重要因素。2）颜色记忆：本研究采用样本匹配任务考察了大学生对不同色调颜色刺激的记忆差异。在明视条件下，在CRT上呈现样本刺激，然后延迟3秒呈现匹配刺激。受试者被要求从两个匹配的刺激中识别样本刺激。正确响应百分比在绿色中最高，在蓝色中最低。相反，辨别力得分在绿色中最低，在蓝色中最高。这些数据表明，色彩对颜色的工作记忆有显著的影响。3）Pokemon患者的光驱动。以3-20 Hz的频率提供重复闪光。4）对颜色刺激的前脉冲抑制15名受试者在100 ms的超前时间内观察了颜色前脉冲对惊眼眨眼反射的影响，结果表明，预先给予颜色刺激可显著抑制对角膜突然吹气的眨眼反射幅度。黄色的压制效果最好。因此，我们得出结论，黄色是最有效的抑制情绪和惊吓反应。
