【摘要】：抑制控制功能是執(zhí)行功能的一個核心子成分,主要負(fù)責(zé)壓抑或阻止與當(dāng)前認(rèn)知加工無關(guān)的信息和行為。Zelazo等人在認(rèn)知復(fù)雜性和控制理論的基礎(chǔ)上,將抑制控制功能劃分為冷抑制控制功能和熱抑制控制功能兩大類。冷抑制控制功能屬于純認(rèn)知性的過程,一般由抽象的、去情境化的問題激發(fā),而熱抑制控制功能通常具有高度的情感卷入,個體要對刺激的情感意義做出評價。相關(guān)研究表明,聽障兒童很可能存在抑制控制功能缺陷,但是目前還未有研究證實聽障兒童的冷、熱抑制控制功能是否都存在缺陷?因此,采用適合于聽障兒童被試的晝-夜Stroop范式和Go/Nogo兩個范式,并以非情緒性材料和數(shù)字材料做為冷抑制控制功能的測量材料,以情緒性材料做為熱抑制控制功能的測量材料,分別考察聽障兒童的冷、熱抑制控制功能。實驗一采用晝-夜Stroop范式,實驗設(shè)計為2×2的混合實驗設(shè)計。實驗任務(wù)分為兩個階段,第一階段為非情緒材料的晝-夜Stroop任務(wù),要求被試在看到太陽圖片時反應(yīng)為“黑夜”,在看到月亮圖片時反應(yīng)為“白天”�？疾煸诜乔榫w材料下被試對優(yōu)勢反應(yīng)的抑制控制能力;第二階段為情緒材料的晝-夜Stroop任務(wù),要求被試在看到情緒太陽圖片時反應(yīng)為“黑夜”,在看到情緒月亮圖片時反應(yīng)為“白天”。考察在情緒材料下被試對優(yōu)勢反應(yīng)的抑制控制能力。實驗二采用Go/Nogo范式,實驗設(shè)計為2×2的混合實驗設(shè)計。實驗任務(wù)分為兩個階段,第一階段為數(shù)字材料的Go/Nogo任務(wù),要求被試對數(shù)字“II”做Go反應(yīng)(按鍵),對其它數(shù)字做Nogo反應(yīng)(不按鍵),考察在數(shù)字材料下被試對優(yōu)勢反應(yīng)的抑制控制能力;第二階段為情緒材料的Go/Nogo任務(wù),要求被試對表情圖片做Go反應(yīng),對中立表情做Nogo反應(yīng)�？疾煸谇榫w材料下被試對優(yōu)勢反應(yīng)的抑制控制能力。本研究得到了以下幾個結(jié)論:(1)聽障兒童在反應(yīng)時和錯誤率兩個指標(biāo)上的成績都顯著差于健聽兒童,表明聽障兒童整體的抑制控制功能存在缺陷;(2)在兩個冷抑制控制任務(wù)中,聽障兒童和健聽兒童在反應(yīng)時和錯誤率指標(biāo)上都不存在顯著差異,表明聽障兒童的冷抑制控制功能不存在顯著缺陷;(3)在兩個熱抑制控制任務(wù)中,聽障兒童和健聽兒童在反應(yīng)時和錯誤率指標(biāo)上都存在顯著差異,聽障兒童的反應(yīng)時和錯誤率顯著高于健聽兒童的反應(yīng)時和錯誤率,表明聽障兒童的熱抑制控制功能存在顯著缺陷;(4)聽障兒童的冷、熱抑制控制功能存在分離現(xiàn)象。
[Abstract]:Inhibitory control is a core subcomponent of executive function, which is mainly responsible for suppressing or preventing information and behavior unrelated to current cognitive processing. Zelazo et al., based on cognitive complexity and control theory. The inhibition control function is divided into two categories: cold inhibition control function and thermal inhibition control function. The control function of cold inhibition is a pure cognitive process, which is generally stimulated by abstract, dissitutional problems, while the control function of heat suppression usually has a high degree of emotional involvement, and individuals should evaluate the emotional significance of stimulus. Related studies have shown that children with hearing impairment may have inhibition control function defects, but there is no research to confirm that the children with hearing impairment cold, thermal inhibition control function are there any defects? Therefore, the daytime-night Stroop paradigm and the Go/Nogo paradigm were used for hearing impaired children, and non-emotional materials and digital materials were used as the measuring materials for the control function of cold suppression. The control function of cold and heat suppression in children with hearing impairment was investigated by using emotional materials as the measuring materials for heat suppression control. In experiment 1, a 2 脳 2 hybrid experimental design was designed using the daytime-night Stroop paradigm. The experiment task was divided into two stages. The first stage was the daytime-night Stroop task with non-emotional materials. The subjects were asked to react as "night" when they saw the sun picture and "day" when they saw the moon picture. To investigate the inhibition and control ability of the dominant response of the subjects under non-emotional materials; The second stage was the day-night Stroop task of emotional materials. The subjects were asked to react as "night" when they saw the picture of emotional sun and "day" when they saw the picture of emotional moon. Objective: to investigate the inhibition and control of dominant responses in subjects with emotional materials. The second experiment adopts Go/Nogo paradigm, and the experiment design is a mixed experiment design of 2 脳 2. The experiment task is divided into two stages. The first stage is the Go/Nogo task of digital material. The subjects are asked to do Go response to digital "II" (keystroke) and Nogo reaction to other numbers (no keystrokes). To investigate the inhibition and control ability of the dominant reaction of the subjects under the digital materials; The second stage was the Go/Nogo task of emotional materials, which asked the subjects to do Go reaction to the facial expression picture and Nogo reaction to the neutral expression. Objective: to investigate the inhibition and control of dominant responses in subjects with emotional materials. The results of this study are as follows: (1) the achievements of children with hearing impairment in response time and error rate are significantly worse than those in children with hearing impairment, which indicates that there are defects in the whole inhibition and control function of children with hearing impairment; (2) there was no significant difference in response time and error rate between children with hearing impairment and children with hearing impairment in two cold suppression control tasks, indicating that there was no significant defect in cold inhibition control function of children with hearing impairment; (3) there were significant differences in response time and error rate between hearing-impaired children and hearing-impaired children. The response time and error rate of hearing-impaired children was significantly higher than that of hearing-impaired children. The results showed that there were significant defects in the control function of heat suppression in children with hearing impairment. (4) the control function of cold and heat suppression in children with hearing impairment is separated.
