Abstract
This article outlines Wilhelm Reich's theoretical concept of mother–infant attachment as the origin of self-regulation with a focus on neurophysiological research. Effects of adaptive and maladaptive mother–infant interactions are discussed. The association between emotional trauma and failure of self-regulation is described. Affect dysregulation and developmental factors associated with self-regulation are outlined. Current neurophysiological research findings support Reich's theories regarding the crucial impact of mother–infant attachment on self-regulation.
