This is a book about the past, present and future of personality at work. It begins by introducing the principal concepts of current personality theory. A concerted effort is made to communicate the sense of coherence that exists among the components of personality such as needs, traits, social cognition, and emotions. The `Five Factor Model' of traits is described. This work also gives an overview of the techniques used to evaluate personality and is a useful guide to personality research with suggestions on how it can be integrated into organizational research.
