This document provides an introduction to personality types and the Myers-Briggs Type Indicator (MBTI) assessment. It discusses the origins of the MBTI, describes the 16 personality types identified by the assessment, and gives examples of each type. The goal is to help learners understand their own personality type and how it relates to their preferred learning style. After reviewing the material, learners should be able to identify their type, compare types, and apply types to fictional characters. A number of online resources are referenced for further information.
