Depressive disorders may be characterised by hyperattention toward negative information, hypoattention toward positive information, or a combination of both processing biases. In two studies, a dot-probe task was utilised to better ascertain the specific direction and time-course of these biases. In both studies, the dysphoric group showed significantly less attentional allocation toward positive stimuli than the non-dysphoric group. In study two, the dysphoric group also showed greater attentional allocation toward depression-specific stimuli. Importantly, the bias toward depression-specific stimuli, and the bias away from positive stimuli, were uncorrelated with each other. It may be that both biases can act as sufficient, but not necessary, characteristics of dysphoric processing. An additional possibility is that the relative level of each bias type may best characterise dysphoric processing. Each of these possibilities is discussed in turn.
