This single-blind placebo-controlled study (n=10) investigated the effects of LSD (40-80μg) on lexical retrieval in a picture-naming task and found an increase in the rate at which subjects substituted items with similar words within the same semantic category. These results are consistent with the notion that LSD increases the spread of activation within semantic networks.
