n. in factor analysis, the proportion of variance in one variable that is accounted for by an underlying element common to all of the variables in a set.

action readiness

a state of preparedness for action that is elicited as part of an emotional response and associated with such physiological indicators as changes in heart rate, respiratory rate, and muscle tension. The term is often used synonymously with action tendency but also refers to a general readiness for action that does not involve an urge to carry out a specific behavior.
