Psychological traits such as self-esteem explain how people differ from each other, but what explains the psychological traits and their development? Psychologists tend to explain individual differences and developmental trajectories of traits based on variables that are separate from the traits themselves.

There were promises of engaging talks, enthusiastic poster presentations, and excellent prize-winning articles. In full support of the three Ph.D. students who organized the event, I attended the afternoon and left excited.
