Wealth of evidence has indicated that an abundance of negative biases and a lack of positive biasesin memory could be an important factors in the onset and subsequent maintenance of depression.Moreover, recent studies have suggested that attentional biases influence memory biases and biasesin the information input stage might play a key role in causing these biases. Nevertheless, most studieson memory biases have investigated only recall biases, with only a few studies directly examiningencoding biases. Therefore the relationship between dysphoria and encoding biases was investigatedusing the recognition task described by Müller et al.( 2009). Results indicated that encoding positivewords enhanced encoding preceding and subsequent words in non-dysphoric participants, whereasthis was not the case in dysphoric participants. These results suggest that dysphoria is associated witha paucity of encoding information presented temporally close to positive information. It is suggestedthat future studies should investigate the impact of processing emotional information on processingother types of information in people with depression.
