Thirty unilateral anterior temporal lobectomy (ATL) subjects (15 right
and 15 left) and 15 controls were presented a multitrial learning task in
which unfamiliar faces were paired with biographical information
(occupation, city location, and a person's name). Face recognition
hits were similar between groups, but the right ATL group committed more
false-positive errors to face foils. Both left and right ATL groups were
impaired relative to controls in acquiring biographical information, but
the deficit was more pronounced for the left ATL group. Recall levels also
varied for the different types of biographical information; occupation was
most commonly recalled followed by city name and person name. In addition,
city and person name recall was more likely when occupation was also
recalled. Overall, recall of biographical information was positively
correlated with clinical measures of anterograde episodic memory. Findings
are discussed in terms of the role of the temporal lobe and associative
learning ability in the successful acquisition of new face semantic
(biographical) representations. (JINS, 2005, 11,
