Psychology has been captured by an assumption that is almost totally unrecognized. This assumption?the linearity of time?unduly restricts theory and therapy, yet this restriction is so common, so customary, that it is often completely ignored. This book traces the influence of this assumption and reveals the many overlooked ?anomalies? to its dominance. Slife describes the many findings and explanations that are incompatible with linear time in several psychological specialties. He contends that these unnoticed anomalies point to alternative conceptions of time that offer innovative ideas for psychological explanation and treatment.
