具有強迫症狀的大學生在選擇性注意力之探討

Selective Attention in College Students with Obsessive-Compulsive Symptoms

本研究的目的在探討具有強迫症狀的人在其選擇性注意力上的功能。研究中使用非語文刺激的視空間促發作業。這類型的典範可用來檢測對相關訊息的促發能力與無關訊息的抑制能力。參與者完成健康性格習慣量表與馬氏強迫症狀量表，依據量表分數被區分成三個組別：非焦慮控制組、泛焦慮控制組、強迫症狀組。且所有組別的參與者都完成視空間促發作業。結果顯示強迫症狀組的抑制效果量顯著低於其他二組控制組，這個結果推測，具有強迫症狀的人會有較少的認知抑制的功能。與過去的研究發現相反，我們的結果顯示強迫症狀的人會在空間位置上顯示出有抑制缺損的情況。

The goal of the present study was to explore the function of selective attention in people with obsessive-compulsion symptoms. The visuospatial priming paradigm with non-verbal stimulus, e.g., location, was employed in this study. The paradigm was designed to examine the ability of facilitating
the relevant information and/or inhibiting the irrelevant information. All participants completed the Health Personality Habits Inventory, and Maudsley Obsessional-Compulsive Inventory, and they were classified into three groups, non-anxious control group, general-anxious control group, and obsessionalcompulsive group based on the screening score reflected on the two Inventories. They further performed the visuospatial priming paradigm. The result showed that the inhibition effect is significantly smaller in the obsessional-compulsive group than the other two groups. Contrary to the previous finding of no diminished inhibition, our results show that people with obsessive-compulsion symptoms suffered from inhibition deficit on the location-based priming task.
