Types of Psychology: Evolutionary
Mental processes exist because they serve an evoluntionary purpose, they aid in survival and reproduction
Types of Psychology: Psychodynamic
Empasizes behavior is determined by your past experiences that are left in the unconscious mind and childhood experiences
Types of Psychology: Cognitive
Focuses on internal processes of the mind influencing behavior
Types of Psychology: Biological
The influence of genetics and brain chemistry (physical and biological processes)
Types of Psychology: Sociocultural
Focuses on society and culture in terms of our behavior and shaping cognition
Types of Psychology: Behavioral
Focus on observable behaviors, people/animals are controlled by their enviornment, positive/negative consequences
