Is there a "special relationship" between unconscious emotions and visual imagery? Evidence from a mental rotation test.

There is an increasing interest in the relationship between imagery and emotion (e.g., Holmes & Mathews, 2005). The present research examined whether unconscious emotions affect visual imagery. In particular, participants were invited to perform a mental rotation test following subliminal presentation of happy, sad and neutral expressions. This study revealed an increase in mental rotation abilities after unconscious visual processing of emotional expressions. Altogether, these findings support the hypothesis of a bidirectional relationship between imagery and emotions.
