Memory and hedonic tone: 'personality' or 'mood' congruence?

Four groups of healthy women matched for age and IQ were reliably classified on the Eysenck Personality Questionnaire as being either high or low in extraversion or neuroticism. As part of a larger research project, each participant was administered a range of psychometric measures together with three paired-associate learning lists varying in hedonic tone and difficulty levels together with the Beck Depression Inventory. Performance on the hedonic lists covaried with personality categories but, unlike what typically obtains in clinical patients, less association emerged between performance and mood states. Performance was particularly polarized in women scoring high in neuroticism but low in extraversion. Speculations about the apparent correlates of so-called mood congruence in healthy subjects are put forward and parallels are drawn with studies reporting the phenomenon in clinically depressed patients.
