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.

我们进行了以下四个实验。1）对颜色刺激的简单反应时间。我们测量了健康本科生对不同色调、饱和度或亮度的简单反应时间（RT）。 RT 到红色和绿色的速度较快，而到蓝色的速度最慢。饱和度对反应时间没有影响。使用SD方法评分的颜色偏好对蓝色最高，对黄色最低，因此观察到偏好与RT之间没有显着相关性。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。我们通过样本匹配任务研究了本科生对不同色调的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。绿色的正确反应百分比最高，蓝色的正确反应百分比最低。相反，绿色的歧视得分最低，蓝色的歧视得分最高。这些数据表明，色调对颜色的工作记忆有显着影响。3）神奇宝贝患者的光驱动。脑电图记录了因观看电视上的神奇宝贝电影而遭受痛苦的患者。以 3-20 Hz 的频率发出重复的闪光。 α波的诱导现象与正常对照组有显着差异。4）预脉冲对颜色刺激的抑制。在15名受试者中检查了颜色预脉冲对惊眼眨眼反射的影响，领先时间为100毫秒。先前呈现的颜色刺激显着抑制了对角膜突然吹气的眨眼反射的幅度。黄色在抑制方面最有效。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。
