Testosterone induces off-line perceptual learning.

Journal article

RATIONALE: Perceptual learning operates on distinct timescales. How different neuromodulatory systems impact on learning across these different timescales is poorly understood. OBJECTIVES: Here, we test the causal impact of a novel influence on perceptual learning, the androgen hormone testosterone, across distinct timescales. METHODS: In a double-blind, placebo- controlled, cross-over study with testosterone, subjects undertook a simple contrast detection task during training sessions on two...
