Semantic activation in LSD: evidence from picture naming

LSD alters cognition by expanding the breadth of semantic activation. In a picture-naming task with ten participants, LSD reduced accuracy and altered error correction patterns compared to placebo, consistent with an increased spread of semantic activation. These effects align with a generalized entropic effect on the mind. The authors recommend future studies include direct neuroimaging and more naturalistic measures of semantic processing.
