What does the Equipotentiality hypothesis suggest would happen?

Based on his creation of lesions and the animals’ reaction, he formulated the equipotentiality hypothesis: if part of one area of the brain involved in memory is damaged, another part of the same area can take over that memory function (Lashley, 1950).

What did Ebbinghaus forgetting curve demonstrate?

The forgetting curve is a mathematical formula by Hermann Ebbinghaus that originated in 1885.

Most of us never encode the details of the penny. We only encode enough information to be able to distinguish it from other coins. If we don’t encode the information, then it’s not in our long-term memory, so we will not be able to remember it.

Hermann Ebbinghaus (24 January 1850 – 26 February 1909) was a German psychologist who pioneered the experimental study of memory, and is known for his discovery of the forgetting curve and the spacing effect. He was also the first person to describe the learning curve.

Did William James use introspection?

Like Wundt, James also relied on introspection; however, his research approach also incorporated more objective measures as well. Sigmund Freud believed that understanding the unconscious mind was absolutely critical to understand conscious behavior.

What did Karl Lashley conclude about the Engram?

Beginning with Karl Lashley, researchers and psychologists have been searching for the engram, which is the physical trace of memory. Lashley did not find the engram, but he did suggest that memories are distributed throughout the entire brain rather than stored in one specific area.
