Brain Plasticity and Habit in William James: an Antecedent for Social Neuroscience

Abstract

William James, in the chapter on the habits of “The Principles of Psychology” (1890) introduced as a key concept of plasticity of brain and nervous system. James could not study this phenomenon experimentally, but his proposal was derived from the results of contemporary research in different fields of Biology and Physiology. Plasticity refers to how learning, skill acquisition, interpersonal and social influences and other contextual variables can influence on the physical structure of the brain, modifying and establishing new relationships and neural circuits that in turn can impair their functioning. This concept was studied experimentally in the late Twentieth Century, and it’s a key concept in the current Social Neuroscience, a discipline that seeks to combine and integrate different conceptual and methodological elements from Neuroscience and Social Psychology. This analysis has allowed us, first, to emphasize the meaning and value that James gave to the concept of plasticity in its analysis of habit, and second, to review the meaning of this concept in modern Social Neuroscience, stressing background of the James’ hypotheses in the current concept of brain plasticity.
