Attitudes refer to general evaluations people have regarding people, places, objects, and issues. Attitudes serve a number of important functions such as guiding choices and actions and giving people a sense of identity and belonging. Attitudes can differ in the extent to which they come from affect, cognition, and behavior. These bases of attitudes can be appraised objectively and subjectively. Attitudes can also differ in their strength, with some attitudes being more impactful and predictive of behavior than others. Some indicators of attitude strength have been viewed as relatively objective in nature (e.g., stability, resistance, accessibility, spreading) whereas other strength indicators are more subjective in nature (e.g., attitude certainty, subjective ambivalence, perceived moral basis of attitudes). Attitudes can be stored in memory in different ways, including an attitude structure in which attitude objects are linked to both positivity and negatively separately, tagging these evaluations with varying degrees of validity. Finally, after a long tradition of assessing attitudes using people’s responses to self-report measures (explicit measures of attitudes), more recent work has also assessed attitude change with measures that tap into people’s more automatic evaluations (implicit measures of attitudes). Implicit and explicit measures can be useful in predicting behavior separately and also in combination.
