What did the case study of HM show us about memory?
As this task showed, H.M had lost his declarative/explicit memory, but his unconscious procedural/implicit memory remained intact. Given the damage to his hippocampus in surgery, researchers concluded from tasks such as these that the hippocampus must play a role in declarative but not procedural memory.
How is memory tested in psychology?
Observational and experimental methods are used to test children’s memory by documenting either their physical actions, emotional (facial) response or attention/ focus, depending on the age (ability) of the child and the type of task provided.
How do you test memory in an experiment?
Compare random words versus related words. Create two lists of words: One that is completely random and another that has groups of related words. Ask participants to first complete one trial with the random words, and then complete another trial with the related words. Compare the results of the two trials.
What did the case of HM teach us?
The study of H.M. has revolutionized our understanding of the organization of human memory. Particularly his case played a significant role in the development of theories that explain the link between brain function and memory, and in the development of cognitive neuropsychology.
What is the most famous case study in psychology?
The case of Phineas Gage is perhaps the most cited study in psychology. This famous case study showed how different areas of the brain affect personality and cognitive ability.
What is case study method in psychology?
• The case study method often involves simply. observing what happens to, or reconstructing. ‘the case history’ of a single participant or group. of individuals (such as a school class or a specific. social group), i.e. the idiographic approach.
What has the study of H.M. revealed about the role of the hippocampus in memory?
generated five main findings: that memory is a distinct psychological function, that amnesia spares short-term and working memory, that amnesia is an impairment of declarative and episodic memory, that the hippocampus is a core brain structure supporting memory, and that the hippocampus supports the permanent …
What is the role of the hippocampus in memory?
The hippocampus is thought to be principally involved in storing long-term memories and in making those memories resistant to forgetting, though this is a matter of debate. It is also thought to play an important role in spatial processing and navigation.
What questions are in a memory test?
The MMSE includes questions that measure:
- Sense of date and time.
- Sense of location.
- Ability to remember a short list of common objects and later, repeat it back.
- Attention and ability to do basic math, like counting backward from 100 by increments of 7.
- Ability to name a couple of common objects.
What tests are used for memory?
The most common types of tests are:
- Montreal Cognitive Assessment (MoCA) test. A 10-15 minute test that includes memorizing a short list of words, identifying a picture of an animal, and copying a drawing of a shape or object.
- Mini-Mental State Exam (MMSE).
- Mini-Cog.
Why is the case of H.M. so important to the field of neuropsychology and the study of memory?
His case played an important role in the development of theories that explain the link between brain function and memory, and in the development of cognitive neuropsychology, a branch of psychology that aims to understand how the structure and function of the brain relates to specific psychological processes.
