title: Factors of Mouse Emotionality at the Second Order, Third Order, and Fourth Order.
abstract: Data which had previously yielded 15 factors at the first order were reanalyzed to produce six second-order, three third-order and one fourth-order factors. Broad behavioral patterns were discovered which indicate that escape, avoidance, emotionality, and motor reactivity are the primary manifestations of affectivity in a variety of test situations. In spite of difficulties in distinguishing between dimensions at different strata, this investigation constitutes an important contribution to the empirical basis for hierarchical organization of the affective domain.
