采用连续闪烁抑制范式(Continuous Flash Suppression,CFS),通过比较不同美感的图片的突破抑制时间,考察了美感对西方绘画无意识加工的影响。实验1使用黑白噪音图片,通过单因素被试内设计考察了高、中、低三种美感等级的彩色西方绘画的突破抑制时间。结果发现,美感高和美感中等的西方绘画比美感低的西方绘画能更快突破噪音图片的抑制进入意识。实验2考察在彩色噪音图片的抑制下,美感是否依然影响彩色西方绘画突破抑制的时间。结果发现,美感不影响西方绘画突破抑制时间,且突破抑制时间显著长于实验1。这些结果表明美感对西方绘画无意识加工的影响受到双眼竞争的眼间抑制过程的限制,只有在黑白噪音图抑制的情况下,美感会影响西方绘画进入意识的速度。与黑白噪音图片相比,彩色噪音图片可能对颜色信息的抑制更强,干扰了美感对西方绘画无意识加工的影响。
People prefer beautiful visual artworks. Aesthetic experiences to beautiful and ugly images are different. Studies on neuroaesthetics showed different neural responses to beautiful stimuli compared to ugly stimuli. The first stage of aesthetic experience of a visual artwork is visual perception of the stimulus. Most research about aesthetic processing focused on stimuli presented consciously. Little is known about whether aesthetic processing can occur unconsciously. Previous research suggested that both beautiful paintings and attractive faces can elicit activation of the reward circuitry in our brain. Attractive faces break through continuous flash suppression more quickly than unattractive faces. Thus, it is possible that unconscious processing of beautiful paintings is different from that of less beautiful paintings. In two experiments, the present study adopted continuous flash suppression paradigm to investigate whether aesthetic ratings of western paintings influenced the time for stimuli to break suppression. We also compared the suppression effect of achromatic (Experiment 1) and chromatic (Experiment 2) noise pictures.
In Experiment 1, 20 participants (8 females, 12 males) took part in the experiment. The independent variable was aesthetic rating of western paintings (high, average, and low). The achromatic suppression noises were presented to the participants’ dominant eye and continued to flash at 10 Hz. A western painting was presented to the nondominant eye, at either above or below the central cross, with contrast increasing from 0 to 100% within 1s and remaining constant until response. Participants were instructed to respond as accurately and quickly as possible when any part of the painting was detected, and report whether the target was presented above or below the cross. 18 participants (9 females, 9 males) took part in Experiment 2. Experiment 2 was identical with Experiment 1 except that chromatic suppression noises were presented to the dominant eye.
The results of Experiment 1 showed that paintings with low aesthetic ratings took significantly longer time to break into awareness, comparing to paintings with average and high aesthetic ratings. The reaction times were not significantly different between paintings with average and high aesthetic ratings. In Experiment 2, however, the times for breaking suppression were not significantly different among the three categories of paintings. Moreover, the effect of suppression was different between different noises, such that reaction times were longer under suppression by chromatic noises (Experiment 2) than achromatic noises (Experiment 1).
These results suggested different unconscious processing of western paintings with different aesthetic ratings. Similar to attractive faces, paintings with high and average aesthetic ratings were easier to be detected under suppression. Our findings provided evidence that aesthetic processing can occur unconsciously under suppression by achromatic noises. The present study also suggested that the suppression effect of achromatic noises is different from that of chromatic noises. Chromatic noises may interfere with the color information of paintings and disrupt the aesthetic perception of paintings.
