Which of the following best explains why Karl Lashley failed to find the engram, or physical location of memory, in the brain?

• A. He used incorrect chemical formulas to identify memory traces.
• B. Memory is distributed throughout the brain rather than localized to a single area.
• C. The engram is located exclusively in the cerebellum, which Lashley did not examine.
• D. Lashley only studied emotional responses and not memory processes.

Answer: (B)

Verified step by step guidance

1. Understand the concept of the engram, which refers to the physical trace or location of memory in the brain.
2. Review Karl Lashley's research approach, where he attempted to locate the engram by making lesions in different parts of the brain and observing the effects on memory.
3. Recognize that Lashley found that no single brain area was solely responsible for memory, leading to the conclusion that memory is not localized but rather distributed across various brain regions.
4. Evaluate the incorrect options: Lashley did not use chemical formulas, the engram is not exclusively in the cerebellum, and Lashley studied memory processes, not just emotional responses.
5. Conclude that Lashley's failure to find a specific engram location supports the idea that memory is distributed throughout the brain rather than localized to a single area.
