Negativity bias in attitude learning: a possible indicator of vulnerability to emotional disorders?

Negativity biases, i.e., tendencies for negative features and interpretations to predominate over positive, are known to play a role in the etiology and maintenance of emotional disorders. Both depression and anxiety have been associated with such negative cognitive styles. Recently, Fazio, R.H., Eiser, J.R., and Shook, N.J. [(2004). Attitude formation through exploration: Valence asymmetries. Journal of Personality and Social Psychology, 87, 293-311] have observed similar valence asymmetries in the domain of attitude formation and generalization. The present research examined the possibility that the extent to which individuals display a learning bias in attitude formation is related to negative cognitive style and emotional disorder symptoms. Participants played a computer game that required learning whether novel stimuli produced positive or negative outcomes. Poorer learning was associated with more negative cognitive style, greater depression, and a tendency toward greater anxiety. Interestingly, these relations were most evident with respect to the learning of the positive stimuli, suggesting that an under-appreciation of positive objects and events may underlie vulnerability to emotional disorders. The potential value of various indices of negativity bias that can be assessed when examining attitude formation and generalization is discussed.
