The Method of Negative Instruction: Herbert S. Langfeld's and Ludwig R. Geissler's 1910-1913 Insightful Studies.

Herbert S. Langfeld and Ludwig R. Geissler published insightful articles during the period of 1910-1913 using what they called the Method of Negative Instruction, which anticipated much current research on action control and the role of instructions. We review their studies and relate the findings to contemporary research and views concerning task-irrelevant congruency effects and deception, concluding that their work has not received the credit it warrants. We also call for contemporary researchers to revisit prior studies, especially ones conducted before the cognitive revolution in psychology, to enrich their knowledge of the field and improve the quality of their research.
