This investigation examined how hemispheric asymmetry and interhemispheric processing contribute to attentional biases toward emotional information. Participants (n = 88) named the color of lateralized squares presented concurrently with neutral, positive, or threatening words. A left-hemisphere advantage in color naming was reduced when distractors were emotional, suggesting right-hemisphere priming by emotional stimuli. Furthermore, the advantage of dividing the word and color across visual fields was increased for emotion words when they were frequently presented, indicating a strategic use of interhemispheric division of labor to reduce the distracting effect of emotional words. Finally, participants with high levels of anxious apprehension were most likely to make use of this interhemispheric processing strategy, supporting a processing efficiency theory of cognitive function in anxiety.
本研究考察了半球不对称性和半球间加工如何导致对情绪信息的注意偏向。参与者（n = 88）命名与中性、积极或威胁性词语同时呈现的侧向方块的颜色。当干扰物带有情绪色彩时，颜色命名中的左半球优势会减弱，这表明情绪刺激会启动右半球。此外，当情绪词频繁呈现时，跨视野呈现词语和颜色的优势会增加，这表明人们会策略性地利用半球间的分工来减少情绪词的干扰作用。最后，焦虑担忧程度高的参与者最有可能利用这种半球间加工策略，这支持了焦虑中认知功能的加工效率理论。
