    摘要: 對於威脅刺激加以快速偵測並給予較多的注意力，將有利於個體的生存。本計畫的目的，即在於探討威脅刺激對於注意力的影響，及其是否可受由上而下之注意力控制的調節。本計畫擬針對一般的參與者，採用線索提示作業分離「注意力投注」與「注意力移除」兩成份；威脅刺激則為生氣臉孔。線索提示作業採外因提示，以誘發反射性注意力導引，提示線索則包括生氣、快樂與中性臉孔三種情況，採用基模臉為刺激。實驗操弄線索出現與目標刺激出現之間的間距 (SOA)，以觀察時間向度上的變化，以及操弄有效線索比例，以觀察由上而下的注意力控制是否造成影響。在依變項方面，同時測量反應時間與事件關聯電位(ERPs)，藉此可相互驗證。預期所得的成果，將可對生氣臉孔影響注意力的細部運作及全貌，得到更為深入的瞭解，並可瞭解「反射性注意力導引」與「由上而下的注意力控制」之間的互動關係，及其在時間向度上的變化情況，對於情緒研究以及注意力運作的理論探討，將具有重要的貢獻。
    Fast detection of threatening stimuli and demanding more attentional resources to them were assumed to be helpful for the survival of the individuals. Relevant to this view, the purpose of this project is to explore the effect of threatening stimuli on attention using exogenous cuing task. With this paradigm, the engagement and disengagement components of attention can be decomposed. In addition, the interaction between top-down attentional control and the reflexive orienting induced by exogenous cue can be investigated. In this project, participants will be recruited from the normal population. Three kinds of schematic face (angry, happy and neutral face) are included as the cues in the cuing task. Among them, the angry face is a threatening stimulus. The cuing effect of angry face and happy face will be compared with neutral face condition. Stimulus-onset-asynchrony (SOA) between the cue and target is manipulated to observe the time course of the effects. The percentage of valid trials is also manipulated to observe the modulation effects of top-down control, in short SOA and long SOA separately. Both reaction times and event-related potentials are measured using a go/no-go paradigm. The expected outcome of this project will help to understand the effect of angry face on attention more thoroughly and more deeply. Contributions to the emotion studies and understanding of the attention processes can be anticipated.
