Fig. 24.--Here the stimulus-response diagram is complicated to take account of the emotional state. The ellipse here stands for the brain. S arouses T, a tendency towards the response R. But T also arouses P, a bodily state of preparedness, and sensations (E) of this bodily state, together with T, constitute the conscious state of the individual while he is tending towards the response, or end-result, R.
Emotion Sometimes Generates Impulse
Typically, impulse generates emotion. The reaction tendency is primary and the emotion secondary.
But suppose the organic state of fear to be [{133}] present--never mind how it got there--might it not act like hunger or fatigue, and generate a fear impulse? Could it not be that a person should first be fearful, without knowing what he was afraid of and without really having anything to be afraid of; and then, as it were, find something to be afraid of, something to justify his frightened state? This may be the way in which abnormal fears sometimes arise: a naturally timid individual is thrown by some obscure stimulus into the state of fear, and then attaches this fear to anything that suggests itself, and so comes to be afraid of something that is really not very terrific, such as the number two, "I mustn't do anything twice, that would be dangerous; if I do happen to do it twice, I have to do it once more to avoid the danger; and for fear of inadvertently stopping with twice, it is best always to do everything three times and be safe." That is the report of a naturally timorous young man. We all know the somewhat similar experience of being "nervous" or "jumpy" after escaping from some danger; the organic fear state, once aroused, stays awhile, and predisposes us to make avoiding reactions. In the same way, let a man be "all riled up" by something that has happened at the office, and he is likely to take it out on his wife or children. Slightly irritating performances of the children, that would usually not arouse an angry reaction, do so this evening, because that thing at the office has "made him so cross."
In the same way, let a group of people get into a very mirthful state from hearing a string of good jokes, and a hearty laugh may be aroused by a feeble effort that at other times would have fallen flat.
In such cases, the organic state, once set up in response to a certain stimulus, persists after the reaction to that stimulus is finished and predisposes the individual to make the same sort of reaction to other stimuli.
Emotion and Instinct
Anger, fear, lust, the comfortable state appropriate to digestion, grief (the state of the weeping child), mirth or amusement, disgust, curiosity, the "tender emotion" (felt most strongly by a mother towards her baby), and probably a few others, are "primary emotions". They occur, that is to say, by virtue of the native constitution, and do not have to be learned or acquired through experience. They are native states of mind; or, as modes of behavior, they are like instincts in being native behavior.
