    Abstract: 人的認知資源是有限的,如何將注意力投注在關鍵的人事物,對於生存極其重要。注意力的導引可被區分為由刺激特性驅動或是由目標導向的控制方式,而依附性導引(contingent reorienting)則是同時根據兩種控制所產生的注意力導引過程。過去的神經造影研究指出腹側及背側的注意力網路和依附性導引有密切的關係,然而這些發現大多建立在相關性的神經造影證據,缺乏因果性證據的支持與時序上詳細的動態變化。
    ;In the visual world, rapidly reorienting to relevant objects outside the focus of attention is vital for survival. This ability from the interaction between goal-directed and stimulus-driven attentional control is termed contingent reorienting. Neuroimaging studies have demonstrated activations of the ventral and dorsal attentional networks are related to contingent capture, but the causal evidence and the temporal dynamics of the attentional networks still remain unclear. Hence, this thesis used transcranial magnetic stimulation (TMS) and electroencephalography (EEG) to investigate the underlying neural mechanism of contingent reorienting. The TMS results demonstrate a critical involvement of the right ventral attentional network in contingent reorienting and reveal the spatial selectivity within such network. On the other hand, the EEG results show that theta band oscillations and inter-trial coherence varied between hemispheres and experimental sessions during contingent reorienting. Overall, these findings elucidate the natures of attentional control with causal evidence and temporal profile.
