Final answer:
Attitudes are our evaluations or feelings toward a person, idea, or object and can be influenced by internal and external factors, such as cognitive dissonance and advertising.
Step-by-step explanation:
Attitudes are our evaluations or feelings toward a person, idea, or object and typically are positive or negative. Our attitudes and beliefs are influenced not only by external forces, but also by internal influences that we control.
An internal form of attitude change is cognitive dissonance or the tension we experience when our thoughts, feelings, and behaviors are in conflict. In order to reduce dissonance, individuals can change their behavior, attitudes, or cognitions, or add a new cognition.
External forces of persuasion include advertising; the features of advertising that influence our behaviors include the source, message, and audience.
