Mood and belief-value correlation

This is an investigation of belief-value distortion as measured by the correlation between sets of beliefs and values for a given attitude object. Correlations were computed for each subject separately. Initial mood levels and mood changes subsequent to ratings of attitudes to nuclear power were investigated in the first two studies. In Study 1 mood changes were positively correlated with attitude. In Study 2, mood levels were positively correlated both with attitude, optimism, and tendency towards extreme belief-value correlations (belief-value distortion). In a third study, attitudes were studied both towards nuclear power and alcohol. There were no clear relations between the two fields of contents. Mood changes were small and inconsistent. However, tendency to act correlated with both optimism and belief-value distortion, also with the level of attitude kept constant. A model relating mood, optimism, belief-value distortion, and action is suggested.
