There are numerous theories surrounding learning styles. One commonly known theory is the Meyers-Brigg Type Indicator (MBTI), which is based on the analytical studies of psychologist Carl Jung. Jungian theory claims that there are typical psychological properties that are characteristic to each personality type. Basically, there are four learning styles in total (technically, eight opposing personality types) that have been realized most effectively in matters of educating.
To begin with there are either extrovert types or introvert types, and the way each of these personalities absorb and/or react to certain stimuli (be it life or lesson) differs greatly. Extroverts view their world externally -- through things outside themselves, inclusive of everything and everyone around them. The introvert, contrarily, views the world internally, within himself, through his own musings and ideas, rather than through his external experience.
"Sensors" view things with a practical perception; they are detail-oriented and focus on factual information. The sensors counterpart, the intuitive type, relies heavily upon his imagination, while focusing on the meaning of things and their vast possibility -- without requiring factual evidence of any such concept.
Thinkers are skeptical. Their decisions are entirely logic-based and rule-abiding -- void of emotional influence. Feelers are entirely the opposite, and reflect on the world through human consideration and personal experience.
Finally, there are "judgers," who must follow set agendas and plans in a regulated manner. They are rather rigid in their ideals, and decisions are firmly met. The "perceiver," on the other hand, is always adapting and adjusting to the ebb and flow of life's unforeseeable circumstances, forever maintaining flexibility.
These personality types will typically follow a prescribed path in their learning styles -- in their methods of absorbing and processing information. Knowing which personality type you are enables you to process information in a more effective manner. Even more helpful is finding an instructor who can aid you in the enhancement of your intellectual capacity by training you in a manner by which you are most open to receiving any presented information.
It's important to know that it's possible (and very likely) that you're a combination of these personality types -- not necessarily of opposing personalities, but a mixture of the others, and as such can be influenced by various learning styles simultaneously.
