Mental imagery attracts attention to imagery-matching stimuli. However, it remains unknown whether voluntarily imagined atypical color also attracts attention to a stimulus that matches the imagery when the imagined stimuli are color-diagnostic objects, which are strongly associated with typical color. This study investigated whether people can voluntarily imagine atypical colors of such objects and attend to imagery-matching stimuli. Participants in the imagery group were instructed to imagine an atypical color of the black-white objects according to the instructed color or voluntarily selected color, whereas participants in the control group were instructed to attend to the objects without any instruction of imagery. Thereafter, they detected a color target in a visual search task. Results revealed that participants in the imagery group directed attention to the imagery-matching atypical color, not to the original color of the object in the search. Meanwhile, participants in the control group did not demonstrate any attentional guidance. These results suggest that voluntarily imagining atypical color can attenuate mental representations of the original color imagery and change attention to a stimulus that matches imagery.
心理意象会将注意力吸引到与意象匹配的刺激上。然而，当想象的刺激是与典型颜色紧密相关的颜色诊断物体时，自愿想象的非典型颜色是否也会将注意力吸引到与意象匹配的刺激上，这一点仍然未知。本研究调查了人们是否能够自愿想象此类物体的非典型颜色并关注与意象匹配的刺激。意象组的参与者被要求根据指示的颜色或自愿选择的颜色想象黑白物体的非典型颜色，而对照组的参与者被要求在没有任何意象指示的情况下关注物体。此后，他们在视觉搜索任务中检测颜色目标。结果显示，意象组的参与者将注意力导向与意象匹配的非典型颜色，而非搜索中物体的原始颜色。与此同时，对照组的参与者没有表现出任何注意力引导。这些结果表明，自愿想象非典型颜色可以削弱原始颜色意象的心理表征，并将注意力转移到与意象匹配的刺激上。
