According to the College Board, "Psychologists use theory to categorize and explain different personalities. These explanations have been influenced by the various branches of psychology ๐ง Some psychologists study what motivates us ๐and/or our emotional responses to experiences to understand our individual differences. Other psychologists seek to understand personality, including why different personalities exist, how they are developed, and if and how they change.
Originating from the psychodynamic perspective, the study of personality involves consideration of behavior and mental processes and how they interact to produce an individualโs personality. A full explanation of personality also involves incorporating humanistic and social-cognitive perspectives from earlier units โฌ ๏ธ."
This unit seeks to understand the origins of personality, what makes individual personalities different from one another ๐ช, the different psychological perspectives of personality, and how personality can change abruptly depending on the situation a person is faced with. At the same time, this unit is studying what motivates our behaviors and emotions, the process of emotions, and how stress and health โค๏ธ of everyday life pressures can affect us.
About 11-15% of the exam is on this unit.
Main contribution is James-Lange theory, which says physiological arousal comes before emotion.
The first theory, which was the common sense theory, told us, โwe cry because we are sad.โ The conscious awareness came first and the feeling followed. Pioneering psychologist William James felt this was backwards; โwe feel sorry because we cry, angry because we strike, afraid because we trembleโ Danish Psychologist Carl Lange also proposed the same thing. Thus, it is called the James-Lange theory**.**

Despite the studyโs flaws, misleading findings, and lack of a representative sample, his findings are considered as relevant as those found in surveys given today. His study opened the door for more studies into sexual behavior.
His theory suggests that not all needs are equal. He described a hierarchy of needs that predicts what needs have to be fulfilled first and which follow after. By completing this hierarchy ๐บ, we can then fulfill our unique potential as a person. He produced this theory by studying healthy people, who he felt achieved their full potential, and looking at all the things that they had in common.
His theory suggests that following physiological arousal, people look to their environment ๐ณ to determine the exact emotion they are feeling.
