What is the meaning of equipotentiality?
having the same potential
: having the same potential : of uniform potential throughout equipotential points.
What is equipotentiality of the cortex?
n. 1. Karl S. Lashley ‘s hypothesis that large areas of cerebral cortex have similar potential to perform particular functions, including learning and other complex processes (e.g., maze navigation), so that intact cortical areas may take over functions of damaged or destroyed areas.
What does the principle of equipotentiality state?
His complementary principle of “equipotentiality” stated that in the event of damage to one area of the brain, other parts of the brain can sometimes assume the role of the damaged region.
What’s the difference between the concept of strict localization and relative localization?
Strict localization is the idea that very particular parts of the brain perform particular functions. What is strict localization? Relative localization is the idea that different functions are handled by larger areas, like hemispheres.
Who introduced 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 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.
Is the equipotentiality premise true?
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.
Who believed in equipotentiality?
Equipotentiality refers to a psychological theory in both neuropsychology and behaviorism. 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]”.
What is equipotentiality?
Equipotentiality is subject to the other term Lashley coined the mass action principle. This principle postulates that the efficiency of any complex function of the brain is reduced proportionately to how much damage the brain as a whole has sustained, but not to the damage of any particular area of the brain.
What is mass action and equipotentiality in psychology?
Principal of mass action: Proportion of brain damage directly proportional to decrease cognitve ability Principal of Equipotentiality: Ability of intact parts of brain to carry out functions of lost/destroyed parts
What is strict localization of the brain?
Strict localization: Specific parts of the brain are solely responible for specific functions Principal of mass action: Proportion of brain damage directly proportional to decrease cognitve ability Principal of Equipotentiality: Ability of intact parts of brain to carry out functions of lost/destroyed parts
