情緒面孔加工的大腦功能偏側(cè)化與兩半球的相互作用:效價和喚醒度的影響

發(fā)布時間:2018-10-23 19:09
【摘要】:目的:探究效價和喚醒度對情緒面孔加工大腦功能偏側(cè)化的影響,以及這種效應(yīng)如何受到發(fā)生在另一側(cè)半球的閾下情緒面孔加工的影響。方法:采用半視野速示術(shù)在單側(cè)或雙側(cè)同時呈現(xiàn)高興或恐懼情緒面孔。單側(cè)呈現(xiàn)條件下只在一側(cè)呈現(xiàn)一個閾上面孔作為目標(biāo)刺激;雙側(cè)呈現(xiàn)條件下在一側(cè)呈現(xiàn)一個閾上面孔,同時在另一側(cè)閾下呈現(xiàn)一個面孔。實(shí)驗(yàn)采用2(效價:高興、恐懼)×2(喚醒度:高、低)×2(視野:左、右)×2(刺激呈現(xiàn)條件:單側(cè)、雙側(cè))四因素被試內(nèi)實(shí)驗(yàn)設(shè)計,其中,雙側(cè)呈現(xiàn)面孔的效價和喚醒度均包含2(一致性:一致,不一致)。實(shí)驗(yàn)中被試的任務(wù)是對呈現(xiàn)在任意一側(cè)的閾上面孔進(jìn)行效價判別。結(jié)果:(1)當(dāng)目標(biāo)面孔呈現(xiàn)在左視野時,在單側(cè)和雙側(cè)條件下的反應(yīng)都明顯快于右視野,且單側(cè)呈現(xiàn)的反應(yīng)要快于雙側(cè)呈現(xiàn);但是,當(dāng)目標(biāo)面孔呈現(xiàn)在右視野時,在高喚醒度情況下對高興面孔的反應(yīng)快于對恐懼面孔的反應(yīng),在低喚醒度情況下對恐懼面孔的反應(yīng)快于對高興面孔的反應(yīng);當(dāng)目標(biāo)面孔為高喚醒度時,對單側(cè)呈現(xiàn)的面孔的加工快于對雙側(cè)呈現(xiàn)的面孔的加工。(2)在雙側(cè)效價一致條件下,高興面孔呈現(xiàn)在左視野的反應(yīng)顯著快于右視野,但總體上出現(xiàn)在喚醒度不一致條件下。(3)在雙側(cè)喚醒度一致條件下,高喚醒度的高興面孔在效價一致條件下的反應(yīng)顯著慢于效價不一致條件;在右視野呈現(xiàn)條件下低喚醒度的恐懼面孔的反應(yīng)快于低喚醒度的高興面孔。結(jié)論:(1)右半球?qū)λ星榫w面孔的加工存在優(yōu)勢,并且這種加工優(yōu)勢非常穩(wěn)定,雖然左半球加工閾下情緒面孔會對右半球加工閾上情緒面孔造成干擾,但是右半球的情緒加工優(yōu)勢依然存在,只有在左半球加工不一致效價的閾下情緒面孔時,右半球的優(yōu)勢效應(yīng)才消失。(2)對情緒面孔的反應(yīng)并不單純因效價的分類而不同,喚醒度會影響對情緒面孔的反應(yīng),甚至影響力更大。(3)效價和喚醒度的情緒動機(jī)趨勢共同影響不同意識水平上兩半球?qū)η榫w面孔的加工。(4)高喚醒度的無意識恐懼會促進(jìn)有意識情緒面孔的加工。
[Abstract]:Aim: to investigate the effects of titer and arousal on the lateralization of emotional face processing in the brain and how this effect is affected by subthreshold emotional face processing in the other hemisphere. Methods: half-field visualization was used to present happy or fearful faces on one or both sides. Only one suprathreshold face appears as the target stimulus on one side, and one suprathreshold face on one side and one face under the other side on both sides. Two (titer: happy, fear) 脳 2 (arousal degree: high, low) 脳 2 (field of vision: left, right) 脳 2 (stimulus presentation condition: unilateral, bilateral) were used in the experiment, in which, Both the titer and arousal of the face on both sides include 2 (consistency: consistency, inconsistency). The task of the experiment was to determine the titer of the superior face on either side. Results: (1) when the target face was present in the left visual field, the response of the target face in the unilateral and bilateral visual field was significantly faster than that in the right visual field, and the response of the unilateral face was faster than that of the bilateral visual field, but when the target face was present in the right visual field, In the case of high arousal, the response to the happy face was faster than that to the fear face, and in the case of low arousal, the response to the fear face was faster than to the happy face, and when the target face was high arousal, The processing of the faces presented on one side was faster than that on the two sides. (2) the response of happy faces in the left visual field was significantly faster than that in the right field under the condition of the same titer of both sides. However, under the condition of inconsistent arousal degree, (3) under the condition of the same arousal degree on both sides, the response of the happy face with high arousal degree was significantly slower than that under the condition of inconsistent titer. The response of fear faces with low arousal was faster than that of happy faces with low arousal under the condition of right visual field. Conclusion: (1) the processing advantage of all emotional faces in the right hemisphere is very stable, although the processing of subthreshold emotional faces in the left hemisphere may interfere with the processing of the upper emotional faces in the right hemisphere. However, the emotional processing advantage of the right hemisphere still exists. Only when the left hemisphere processes subthreshold faces with inconsistent titers, the dominant effects of the right hemisphere disappear. (2) the responses to emotional faces do not differ solely from the classification of the titers. Arousal affects the response to emotional faces, (3) the tendency of emotional motivation of titer and arousal degree affects the processing of emotional faces in the two hemispheres at different levels of consciousness. (4) the unconscious fear of high arousal degree promotes the processing of conscious emotional faces.
