A. Postma et al., Effects of testosterone administration on selective aspects of object-location memory in healthy young women, PSYCHONEURO, 25(6), 2000, pp. 563-575
Previous work has indicated that object-location memory is sensitive to sex
differences as well as variations in the menstrual cycle. The goal of the
present study was to further examine the hormonal basis of human spatial me
mory by assessing the effects of a single dose of exogenous testosterone in
healthy young women on three recall conditions: positional reconstruction;
object-to-position-assignment; and the combined condition in which subject
s both have to reconstruct the precise locations and to link the different
objects to the correct places. In the latter condition, delayed recall (3 m
in delay) improved with testosterone. Although the effects were only small
and need further substantiation, they support the idea that testosterone ma
y have an activational effect on selective aspects of cognitive functioning
