Effects of chronic non-clinical depression on the use of positive and negative words in language contexts.
The purpose of this study was to investigate the effects of chronic non-clinical depression (ChD) on the use of ambiguous and unambiguous emotional words in language contexts. Participants with ChD and normal non-depressed (ND) participants' responses to positive and negative stimulus words on a free association word test were compared using the Hyperspace Analogue to Language (HAL) model of memory's context density metric, a measure of the range of contexts in which a word is used in language. ChD participants generated negative words that were used in more restricted contexts than ND participants. However, ND and ChD participants used positive words in a similar range of contexts. The results suggest that people with ChD tend to use negative words that are probably more negative in connotation, yet they are not impaired with respect to using words in contexts where positive words are required.
