The human personality is analogous to a mosaic or jigsaw puzzle. It is a collection of multifaceted aspects that each contribute a small part towards the construct that is interpreted as "personality." The most prominent theories on personality are based around the concept that personality is split into separate, overlapping, aspects (1). Additionally, individuals can experience mood swings and personality changes, while still retaining the aspects of their personality that allow them to be recognized as themself. This is indicative that there are aspects of personality, rather than a single construct.
