What is the law of equipotentiality?
in learning theory, the principle that any pair of stimuli can be associated with equal ease, regardless of their nature or origin. Also called law of equipotentiality; principle of equipotentiality.
What is flourens theory of equipotentiality?
In neuropsychology, equipotentiality is a neurological principle that describes a cortical mechanism, first identified by Jean Pierre Flourens and later revisited by Karl Lashley in the 1950s. His principle of “mass action” stated that the cerebral cortex acts as one—as a whole—in many types of learning.
What is an example of equipotentiality?
Equipotentiality theory, however, hypothesized that the severity of cognitive dysfunction was directly related to the total amount of tissue damage. For example, memory functioning was thought to be diffusely distributed throughout the cortex rather than related to defined circuits or pathways.
What is equipotentiality language?
Hemispheric equipotentiality refers to a supposed equivalence of the two cerebral hemispheres for basic language capacity. Equipotentiality has taken two different forms: one based on proposals about the anatomical features of the two hemispheres, the other on suppositions about language behavior.
What is equipotentiality premise?
Abstract. The premise of equipotentiality, which has been widely adhered to among learning theorists, states that the laws of learning should not vary with the use of particular stimuli, responses, or reinforcements.
What is the behaviorist principle of equipotentiality?
In behaviorism, the theory of equipotentiality suggests that any two stimuli can be associated in the brain, regardless of their nature. It proposes that all forms of associative learning, both classical (Pavlovian) and operant (Skinnerian) involve the same underlying mechanisms.
What is the significance of the equipotentiality hypothesis?
Equipotentiality is the theory that the brain has the capacity (in the case of injury) to transfer functional memory from the damaged portion of the brain to other undamaged portions of the brain. This hypothesis, put forward by Karl Spence Lashley, is part of his law of mass action.
Who invented equipotentiality?
Equipotentiality – a notion developed by Karl Spencer Lashley (1890–1958) positing that all areas of the brain are equally able to perform a task.
What is the principle of equipotentiality in psychology?
In neuropsychology. The principle of equipotentiality is the idea that the rate of learning is independent of the combination of conditioned and unconditioned stimuli that are used in classical conditioning.
What does Karl Spencer Lashley mean by equipotentiality?
Karl Spencer Lashley defined equipotentiality as “The apparent capacity of any intact part of a functional brain to carry out… the [memory] functions which are lost by the destruction of [other parts]”. In other words, the brain can co-opt other areas to take over the role of the damaged part.
Who was the first person to discover equipotentiality?
In neuropsychology, equipotentiality is a neurological principle that describes a cortical mechanism, first identified by Jean Pierre Flourens and later revisited by Karl Lashley in the 1950s.
Which is the best definition of equifinality?
Equipotentiality: When things with a common origin can go in very different directions of development (e.g., of two abuse survivors, one heals and the other becomes a criminal). For many novices BFST strikes them as too deterministic.
