Effects of color vision on emotion.

我们进行了以下四个实验。1)对颜色刺激的反应时间简单。我们测量了健康大学生对不同色调、饱和度或亮度的简单反应时间。RT到红色和绿色的速度更快，到蓝色的速度最慢。饱和度对反应时间无影响。用SD法对颜色偏好评分，对蓝色的偏好最高，对黄色的偏好最低，因此偏好与RT之间没有显著相关性。这些数据表明，颜色的色调是唤醒和情绪的重要因素。2)彩色记忆。本研究采用样本匹配的方法研究了大学生对不同颜色刺激的记忆差异。在光敏条件下，在CRT上先呈现一个样本刺激，然后再呈现一个匹配刺激，延迟3秒。受试者被要求从两个匹配刺激中识别出样本刺激。正确率用绿色表示最高，用蓝色表示最低。相反，歧视得分在绿色中最低，在蓝色中最高。这些数据表明，色调对颜色的工作记忆有显著影响。3)精灵宝可梦患者的光驾驶。记录了因观看电视上的口袋妖怪电影而遭受痛苦的患者的脑电图。以3-20 Hz的频率重复发出闪光。α波的感应现象与正常对照有显著差异。4)脉冲前对颜色刺激的抑制。研究了15名被试的颜色预脉冲对惊眼眨眼反射的影响，预脉冲时间为100 ms。眨眼反射对突然吹气到角膜的振幅被先前的颜色刺激显著抑制。黄色的抑制效果最好。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.
