Cognitive alteration of feeling states: historical background.
Within the scientific community there is a growing awareness and acceptance of the notion that people do not exist only in a world of physical forces and events. A person's perception of the world in which they live in a world is also defined by their own perceptions, experiences, and biases. In other words, a person responds and reacts, not only to objective or experimenter-defined stimuli, but also to his or her apperceptions and subjectively defined stimuli.
