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]". [ 1 ]
Localization theories can be dated as far back as Aristotle, but the man credited with the beginning concepts of field theory was Jean Pierre Flourens. [citation needed] Field theory is the concept that the brain acts as a single functional unit. He devised the first principle of mass action, stating,
Another debate arose about localization of function or functional specialization versus equipotentiality which played a significant role in the development in behavioral neuroscience. As a result of localization of function research, many famous people found within psychology have come to various different conclusions.
Research and experimentation in the neurosciences requires that some universal consistencies in brain structures must either exist or be assumed to exist. The similarity (produced by homology or convergent evolution) of brain structures allows us to generalize across species. If multiple realizability (especially the generalized form) were an ...
So, different functions could indeed be ascribed to particular regions of the brain, but a finer localization was lacking. Flourens, by destroying the horizontal semicircular canal of pigeons, noted that they continue to fly in a circle, showing the purpose of the semicircular canals. [citation needed]
The term "engram" was coined by memory researcher Richard Semon in reference to the physical substrate of memory in the organism. Semon warned, however: "In animals, during the evolutionary process, one organic system—the nervous system—has become specialised for the reception and transmission of stimuli.
Phonemic processing includes remembering the word by the way it sounds (e.g. the word tall rhymes with fall). Lastly, we have semantic processing in which we encode the meaning of the word with another word that is similar or has similar meaning. Once the word is perceived, the brain allows for a deeper processing.
He was the first chairman of the psychology department at the University of California, Los Angeles and served as president of the American Psychological Association. Franz was the editor of multiple psychological journals and he contributed research to the concepts of neuroplasticity , afterimages and cerebral localization .
