Various theories on learning have been developed with increasing frequency in the last few decades. In order to understand the relationship between these theories, Curry's onion model (Curry, 1983) was developed with four layers -- personality learning theories, information processing theories, social learning theories, and multidimensional and instructional theories.
Personality learning theories define the influences of basic personality on preferences to acquiring and integrating information. Models used in this theory include Myers-Briggs Type Indicator (http://www.cpp-db.com/products/mbti/index.asp), which measures personality in dichotomous terms -- extroversion versus introversion, sensing versus intuition, thinking versus feeling, and judging versus perception, and the Keirsey Temperament Sorter(http://keirsey.com/), which classifies people as rationals, idealists, artisans, or guardians.
Information processing theories encompass individuals' preferred intellectual approach to assimilating information, and includes David Kolb's model of information processing, which identifies two separate learning activities: perception and processing (http://www.businessballs.com/kolblearningstyles.htm).
Social learning theories determine how students interact in the classroom and include Reichmann's and Grasha's types of learners: independent, dependent, collaborative, competitive, participant, and avoidant (http://www.personality-project.org/perproj/others/heineman/grslss.htm).
Multidimensional and instructional theories address the student's environmental preference for learning and includes the Learning Style Model of Dunn and Dunn and the multiple intelligences theory of Howard Gardner (http://www.teresadybvig.com/learnsty.htm). This chapter focuses on this type of learning theory by Howard Gardner.
