Watson had the most influence on Lashley. There has also equipotencialidsd experimental work done on higher apes and also studies done on humans who have suffered brain damage in various ways.

Shaffer Orval Hobart Mowrer E.

He also conducted work on instinct as well as color vision. In this context when we use brain we are referring to the cortex. A Quantitative Study of Injuries to equipotenclalidad Brain disproved the idea of localization and brought to equipotencialiead the idea that the brain and its multiple parts work together for memory and other functions.

He enrolled at West Virginia Universitywhere he had originally intended to become an English major. Lashley was born on June 7, in the town of Davis, West Virginia.

His mother was a stay-at-home parent, and had a vast collection of books in the home. He reached this erroneous conclusion due to imperfect fquipotencialidad methods. In their first experiments, Lashley was in charge of building different mazes for the rats to go through and Franz was in charge of making the lesions in the rats’ brains.

June 7, Davis, West Virginia. He studied many animals and primates, which had been an interest since his freshman year at college.

In Februarywhile doing his teaching at Harvard, Lashley unexpectedly collapsed equipotncialidad was hospitalized. He trained rats to perform specific tasks seeking a food rewardthen lesioned specific areas of the rats’ cortex, either before or after the animals received the training. When speaking of this professor, Lashley wrote, “Within a few weeks in his class I knew cerebtal I had found my life’s work”. It proposes that all forms of associative learningboth classical Pavlovian and operant Skinnerian involve the same underlying mechanisms.

Fellows of the Royal Society elected in The first was his mother Maggie Blanche Spencer. Karl Spencer Lashley June 7, — August 7, was a psychologist and behaviorist remembered for his contributions to the study of learning and memory.

By the s two separate principles had grown out of Lashley’s research: The rats with damaged brains didn’t learn as well as the control rats, but no particular region seemed to be necessary to learn the mazes.

Miller Paul E. Researchers also expanded the study of working memory, central executive, and further research on memory deficits and learning. Views Read Edit View history.

The data gathered from these tend to confirm Lashley’s theories. Fox Robert J.

Lashley contributed to psychology and neuropsychology in a number of ways. Lashley graduated high school at age This starts to go against localization theories which would say that the brain is only functioning in specific regions and the brain’s ability to perform at any given task is only effected by the overall damage to that area of the brain and damage to an unrelated area shouldn’t affect the task.

Lashley offered two generalizations from his research, that recently have cerebgal successfully challenged but nonetheless represent important milestones in the development of neurological theory:. He also argued that elementary sensory input was localized, which is supported by current research. Hull Edward C.

Franz made multiple lesions in specific parts of the brains and after they healed, put them through the maze to see if they had equopotencialidad in finding the food.

In behaviorismthe theory of equipotentiality suggests that any two stimuli can be associated in the brain, regardless of their nature.

After obtaining his Bachelor of Arts at West Virginia University, he was awarded a teaching fellowship at the University of Pittsburghwhere he taught biology along with biological laboratories. Karl Spencer Lashley defined equipotentiality as “The apparent capacity of any intact part of cerrebral functional brain to carry out… the [memory] functions which are lost by the destruction of [other parts]”.

The law of mass action says 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.
