Humans especially learn to use various types of innate behavior such as fear, anger and happiness to cope with external stimuli. Other types of behavior are reinforced and learned through a process called operant conditioning. This thrives through the use of positive and negative reinforcers. When a certain behavior is reinforced, it is likely to occur again. A negative reinforcer strengthens any behavior that reduces or terminates it.
Perception is yet another aspect of behaviorism and learning.
The environment affects an organism after, as well as before, it responds to stimuli and the effect to the stimuli becomes consequence. The occasion upon which behavior occurs, the behavior itself, and its consequences are interrelated in the function of reinforcement. For instance, a man sees a beautiful woman, he decides to approach her with conversation. A man sees an unattractive woman, he decides to avoid speaking to her or making eye contact. In this romantic example, the external stimulus causes the man to behave a certain way, which in turn proves the point that through perception of sight, the man will behave a certain way.
