Presidents of the American Psychological Association. He researched this by looking at the measurement of behavior before and after specific, carefully quantified, induced brain damage in rats.


After obtaining his Bachelor of Arts at West Virginia University, crebral was awarded a teaching fellowship at the University of Pittsburghwhere he taught biology along with biological laboratories. Biographical Memoirs of Fellows equipotencialidqd the Royal Society. However, food avoidance experiments have questioned its application.

A fellow researcher, Shepherd Ivory Franzalso shared the common interest of studying localization and studying only things that could be observed.

First, his publication, Brain Mechanisms and Intelligence: He has said that his father was a kind man. If the area is not destroyed then the cortex can take over another part.

This would suggest that just one part of the brain is not responsible for memory and localization was totally ruled out. Woodworth John B. He was on the road to a full recovery until his trip to France with his wife Clair, where he once again unexpectedly collapsed, but this time to his death on August 7, This led Lashley to conclude that memories are not localized, but that they are widely distributed across the cortex.


He was able to read by the age of four. While there he also carried out research which he used for his master’s thesis.

Explicit use of et al. A Review of General Psychology survey, published inranked Lashley as the 61st most cited psychologist of the 20th century. Ghiselli and Brown did an experiment where they destroyed various subcortical regions of the brain in rats and tested their abilities to learn equipotencialidas compared to rats with no damage done to their brains.

Today we know that distribution of engrams does in fact exist, but that the distribution is not equal across all cortical areas, as Lashley assumed. This page was last edited on 10 Octoberat Lashley did not find a central place for stored memories, which suggests that stored memories are not localized but stored and retrieved in multiple areas.

Franz made multiple lesions in specific parts of the brains and after they healed, put them through the maze to see if they had deficits in finding the food. Lashley graduated high school at age Watson had the most influence on Lashley. Anton Susan H. All articles with unsourced statements Articles with unsourced statements from July Articles with unsourced statements from October Using the idea of equipotentiality we can explain how someone who’s received damage to a specific part of their brain can relearn how to perform actions that were lost due to brain damage.

Through Lashley’s ideas of equipotentiality and the law of mass action, he is saying that the brain is functioning as a whole unit and that over all damage to the brain effects it’s over all functioning. Retrieved November 21, from http: Archived from the original on August 1, This eventually began to soften his vertebrae, and as a result a splenectomy was performed.

June 7, Davis, West Virginia.

Views Read Edit View history. 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 equipotenclalidad training.

From Wikipedia, the free encyclopedia. Lashley was a very active boy, both physically and mentally. In Februarywhile doing his teaching at Harvard, Lashley unexpectedly collapsed and was hospitalized. Sincethe Society has awarded the annual Karl Spencer Lashley Award in recognition of work on the integrative neuroscience of behavior. Lashley contributed to psychology and neuropsychology in a number of ways.

Although Lashley studied many things, his most influential equipotenciaoidad centered around the cortical basis of learning and discrimination. He grew up in a middle-class family with a reasonably comfortable life.

The cortical lesions had specific effects on acquisition and retention of knowledge, but the location of the removed cortex had no effect on the rats’ performance in the maze. Retrieved from ” https: She was a strong advocate of schooling, and she encouraged Lashley intellectually from an early age; as a result he was able to read at the age of four.

Archived from the original on His mother was a stay-at-home parent, and had a vast collection of books in the home. Shaffer Orval Hobart Mowrer E. Fellows of the Royal Society elected in Together the two conducted field experiments and studied the effects of different drugs on maze learning of rats.
