The working of the emotional mind is to a large degree state-specific, dictated by the particular feeling ascendant at a given moment. How we think and act when we are feeling romantic is entirely different from how we behave when enraged or dejected; in the mechanics of emotion, each feeling has its own distinct repertoire of thought, reactions, even memories. These state-specific repertoires become most predominant in moments of intense emotion.
One sign that such a repertoire is active is selective memory. Part of the mind's response to an emotional situation is to reshuffle memory and options for action so that those most relevant are at the top of the hierarchy and so more readily enacted. And, as we have seen, each major emotion has its hallmark biological signature, a pattern of sweeping changes that entrain the body as that emotion becomes ascendant, and a unique set of cues the body automatically sends out when in its grip.
