schmolck Flashcards
medial -
the middles of the body as opposed to lateral
lateral -
towards the side of
bilateral -
2 sides
encephalitis -
rare but serious condition that causes inflammation of the brain
what were the three conditions of schmolcks patients
MTL
HF
HM had dammage to the hippocampus and surrounding areas
Results of task 1-9
Patients with. Damage to the hippocampus were able to name point out and answer questions about objects they were given with accuracy. Also comparable to the control group when asked to give examples of a category
Patients with medial temporal lobe or MTL+ performed less well at this and had difficulty giving examples. Found it most difficult to identify and recall facts about living object comparable to non living
HM performed worst among the patients
results of task 10-13
when MTL patients were asked if an object was real or not all patients performed well but one made 8 errors
all MTL scored well on colouring tasks
pyramid and tree, the MTL scored either below the required 90% accuracy or below the control group
MTL were able to produce regular verbs but performed less well at producing irregular verbs and plurals in contrast
HM performed well on both tasks suggesting that the difficulty with irregular items is associated with anterlaterol temporal cortex damage
What was the aim of schmolcks
To investigate whether the effects of specific brain damage on semantic memory and compare to controls
Determine whether HM was a unique case
What was the procedure of schmolcks
1-9- 9 tests over 5 sessions had to identify sort and define line drawings 24 animals and objects 10-13- Asked whether or not objects were real
How many participants were there
14 altogether 8 controls 3 had MTL+ 2 had HF OTher was HM
What was the conclusion of Schmolcks
Hippocampus is not involved in semantic knowledge
Damage to anterolateral cortex leading to a blurring or overlap of knowledge
Semantic knowledge is associated with ATL
HM was unique due to the large number of grammatical errors
Evaluation of schmolcks
Case studies are rare and small in number which limits the generalisability
Individual differences may account for the variation
Cannot establish relationships between injury and results
Lacks ecological validity and mundane realism as was conducted in a lab so can’t be applied to everyday life
