The process of perception – the very having of experience – is fundamentally affected by unconscious processes. This is the conclusion of an elegant and utterly convincing study of the psychodynamics and social context of forming judgements in everyday life, in science and in group processes. The author, M.L.J. Abercrombie is concerned with the origin and development of judgement, the relation between inner and outer worlds, the selective and interpretative nature of perception and the role of context or total situation. The book is a reminder of the emotional basis of learning.
