In the life of a person, there are probably no events, outside influences or genetic characteristics even approaching the significance of the broad category of acts and actions called parent-child relations. These include decisions and actions and lack thereof from the first day of life and sometimes throughout the life-span. They include learning by example, schooling, disciplining, coping skills, behavioural practices, eating habits, communication skills, conflict management and a plethora of other actions. This book presents new research in this dynamic field.
