【摘要】：目的:探討強迫性障礙(OCD)患者自我加工及熟悉性加工的特點。方法:選取14例符合國際疾病和相關(guān)健康問題統(tǒng)計分類第十版(ICD-10)診斷標(biāo)準(zhǔn)的OCD患者及14例年齡、受教育程度相匹配的正常對照。利用設(shè)置恒定的數(shù)碼相機拍攝被試中性表情的正面像,然后分別利用Photoshop軟件及Morph軟件進(jìn)行面孔標(biāo)準(zhǔn)化處理和不同類型面孔之間的合成。實驗要求被試分別通過左右手按鍵識別混合了任意兩種面孔特征的合成面孔(自我-名人,名人-陌生人,自我-陌生人)中其中一種面孔身份及打亂面孔(打亂的面孔拼湊而成的簡圖)。計算機分別記錄被試對"自我"圖片和"他人"圖片的反應(yīng)速度,取平均值作為被試對該面孔的反應(yīng)時間(s),以每個實驗條件下被試對打亂圖片的識別時間為基準(zhǔn)計算反應(yīng)時間比(校正后的反應(yīng)時間,無單位)。結(jié)果:重復(fù)測量方差分析結(jié)果顯示,OCD患者用右手按鍵對自我[(1.14±0.11)vs.(1.05±0.08)]和名人[(1.09±0.07)vs.(1.12±0.07)]面孔的識別反應(yīng)時間比均大于正常對照(P0.05)。結(jié)論:OCD患者對自我面孔和熟悉性面孔的識別速度可能降低,提示其自我加工和熟悉性加工可能有所受損。
[Abstract]:Objective: to explore the characteristics of self-processing and familiarity in patients with obsessive-compulsive disorder (OCD). Methods: fourteen patients with OCD who met the criteria of International Classification of Disease and related Health problems (ICD-10) and 14 normal controls with matched age and education were selected. The positive images of neutral facial expressions were taken with a constant digital camera, and then the faces were standardized by Photoshop software and Morph software, and the different types of faces were synthesized. The subjects were asked to identify synthetic faces (self-celebrities, celebrities-strangers) that were mixed with any two facial features by using the left-and right-hand keystrokes. One of the face identities of self-strangers and a schematic diagram of disordered faces (disjointed faces). The computer recorded the reaction speed of the subjects to the "self" picture and the "others" picture, respectively. The average reaction time of the face was taken as the average time, and the reaction time ratio was calculated based on the recognition time of the scrambled picture under each experimental condition (the corrected reaction time, no unit). Results: the results of ANOVA showed that the response time ratio of the right hand button to the faces of self (1.14 鹵0.11)vs.(1.05 鹵0.08) and celebrity (1.09 鹵0.07)vs.(1.12 鹵0.07) was higher than that of the normal controls (P 0.05). Conclusion the speed of recognition of self-faces and familiar faces may decrease in patients with OCD, suggesting that their self-processing and familiarity processing may be impaired.
