Cattell's theory of personality includes the concept of the Dynamic Lattice, which illustrates the interrelationships between motivational traits.
The Dynamic Lattice specifically maps the connections among three fundamental types of motivational traits:
The Dynamic Lattice shows how these elements interact. Ergs provide the basic motivational energy, sentiments organize these drives around specific life interests, and attitudes represent the concrete expressions or actions taken towards goals influenced by both ergs and sentiments.
Therefore, Cattell's Dynamic Lattice demonstrates the relationship among ergs, sentiments, and attitudes.
