Another assumption is that human behavior is a series of responses to external stimuli mitigated by people's thoughts, perceptions, moods, and desires.
Cognitive psychology differs from the older, behaviorist approach to human behavior.
Behaviorists believe that all people are essentially the same at birth, but their personality is affected and formed by environmental factors and outside stimuli.
They also believe that behavior can be permanently altered by changing the environment.
These thought processes include reasoning, intelligence, memory, attention, and sensory perception.
Language and how it is used in mental processing is also considered.
The cognitive approach is an area of psychology that focuses on mental processes, perception, and language as a way of explaining and understanding human behavior.
