Abstract :
After the gaze is shifted to some events or objects peripherally, the attention mechanism follows it. It is aimed to investigate the emotion and spatial attention dynamic by neural processing of subsequent expression stimuli. The Posner as a gaze cueing paradigm has been used to study the spatial attention mechanism. It is investigated the effect of expression facial cues and meaningful word targets on event-related potential (ERPs) extracted from recorded Electroencephalography (EEG) as indices of gaze-directed orienting. According to analyzes the ERPs component (P1 and N1), Results show that special attention and motivational significantly approach by happy emotion. Understanding the mental chronometry of joint mutual special attention and emotion is implicated by results.
