When you have certain experiences
We respond with various emotions
Stimulus responses

Just as this is sort of stimulus
Produces this sort of involuntary muscle response

Well, that’s a rather simplified suggestion
Of a complex mental process
But you get the idea
Cause, Effect

Nature endows us at birth with three general patterns of emotional response
Rage: Is the response to the primary stimulus of thwarting
Something interfering with our behavior, our action
Fear: Is the response to loud noises, or loss of support
And the emotional response to love
Is usually the result of a show of affection, or favors

The primary stimulus of thwarting
Something interfering with our behavior, our actions
Fear: Is the response to loud noises, or loss of support
