Attitudes can be defined as an affective feelings of liking or disliking toward an object (which can be basically anything) that has an influence on behavior. As Don Forsyth describes in his text book (Our Social World), an attitude is not a feeling, a cognition, or a form of behavior; instead, attitudes combine all three components in an "integrated affect-cognition-behavior system." What this all means is that attitudes are made of three components that all influence each other. If one component changes, then it influences the entire attitude structure. In addition, each components not only have an influence on the attitude structure as a whole, but also on each other component. Although many people think attitudes are pretty simple (you like something or you don't), you can see that attitudes are actually quite complex and dynamic.
