Ribot, Théodule (1839-1916). Philosopher and pioneer of the modern psychological sciences in France. A professor at the Sorbonne and, from 1889, at the Collège de France, he wrote Les Maladies de la mémoire (1881) and studies on volition, personality, and attention. In these works he stressed the physiological basis of impaired mental functioning, but in his later writings gave increasing weight to emotional and affective factors.
