Part I: Origins of Psychology In psychology there are several perspectives that are used to describe‚ predict‚ and explain human behavior. The three major psychological perspectives are functionalism‚ structuralism‚ and behaviorism. Functionalism stressed the importance of how behavior functions to allow people and animals to adapt to their environments. They included research that involved direct observation of living creatures in their natural settings. They also studied how psychology could be

Later‚ the thalamus evolved to receive sensory input from the midbrain and the hindbrain and to pass it on to cerebrum * Cerebrum integrates sensory and motor
