Anterolateral temporal cortex 1 of 18 Main Aim of the study investigate effects of specific brain damage on semantic memory and compare with a 'control group' 2 of 18 Another Aim of the study To see if HM was unique in terms of brain damage and how it affected his memory 3 of 18 How many ppts? 14 4 of 18 what were the control group matched on? age and education 5 of 18 What did the MTL+ group suffer from? Amnesia due to encephaitis 6 of 18 What damage did the HF patients have? 2 ppts had amnesia with damage limited to hippocampus formation 7 of 18 What damage did HM have, and how? Surgry for epilepsy causing MTL damage 8 of 18 What did the MRI scans measure? Lesions of each patients to make comparisons with results 9 of 18 How many tests were used? 9 different tests over 5 different sessions 10 of 18 What did the tests consist of? 48 line drawings (24 animals, 24 objects) 11 of 18 Describe the HF patients results 100% accurate as were the control group 12 of 18 How did HM do in general? Better than MTL+ group but less well than HF and control group 13 of 18 What is the Quantitative data for shown picture and asked to name? Control: 100% - HF: 100% - HM: 97% - MTL+:75% 14 of 18 Quantitative data for given description and asked to name? Control: 100% - HF: 100% - HM: 66.7% - MTL+: 50% 15 of 18 What is the conclusion about the hippocampus? Its not involved in sematic memory 16 of 18 What is the conclusion abut the ATL? Damage to ATL causes semantic impairment thus semantic knowledge is associated with the ATL 17 of 18 How is HM unique? Scored lower but due to the large number of grammatical errors he made - poor educational upbringing. 18 of 18
