Effects of color vision on emotion.

我们进行了以下四个实验：1)对颜色刺激的简单反应时。我们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较快，对蓝色的反应最慢。饱和度对反应时间没有影响。SD法得到的颜色偏好对蓝色的偏好度最高，对黄色的偏好度最低，因此，颜色偏好性与RT没有显著的相关性。这些数据表明，颜色的色调是唤醒和情绪的重要因素。2)颜色记忆。我们使用样本匹配任务考察了大学生对不同颜色刺激的记忆差异。在明视条件下，先在CRT上呈现一个样本刺激，然后再呈现一个延迟3s的匹配刺激。受试者被要求从两个匹配的刺激中识别出样本刺激。正确回答的百分比以绿色最高，蓝色最低。反之，绿色的辨别分数最低，蓝色的辨别分数最高。3)精灵宝可梦患者的光感驾驶。记录了在电视上观看精灵宝可梦电影的患者的脑电。重复闪光频率为3~20赫兹。4)预脉冲对颜色刺激的抑制。对15名受试者进行了颜色预脉冲对惊恐眨眼反射的影响，超前时间为100ms。对突然吹到角膜的空气的眨眼反射的幅度显著地被先前的颜色刺激所抑制。黄色抑制效果最好。因此，我们得出结论，黄色在抑制情绪和惊吓反应方面最有效。

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.
