Question

Quizplus · Accepted Answer

Lashley's experiments on rats demonstrated that the two most important factors affecting learning loss were the amount of brain tissue destroyed and the difficulty of the tasks the rats had previously learned. This led to the formulation of the principles of mass action and equipotentiality, emphasizing the role of the total mass of brain tissue rather than the specific locations of the lesions.
