In the preface to the American edition, the author writes: The volume is not restricted to a critical presentation of those aspects of Gestalt psychology which seem significant to me. Rather, in addition, it offers results of an experimental approach to new problems from the Gestalt viewpoint ... primarily ... Gestalt laws governing mental work, the phenomena ... [of] `connective inhibition' and `mental dazzle' as they appear in thought processes, and the transposition of action forms.
