Investigated Pavlovian conditioning of taste aversion in healthy humans using motion sickness as the unconditioned stimulus (US). 90 Ss (mean age 25.9 yrs) were pretested for susceptibility to illusory motion (vection) in a rotating drum. 32 Ss susceptible to pseudomotion were assigned randomly to 2 groups and received either water 1 hr before rotation and a novel taste (elderberry juice, conditioned stimulus, [CS]) immediately before rotation in a rotating chair (conditioning group), or the sequence of water and juice was reversed (control group). During the test session 1 wk later, all Ss were exposed to water 1 hr before and juice immediately before rotation. The amount of liquids ingested, nausea ratings, rotation tolerance, and blood levels of hormones were evaluated. Ss in the conditioning group developed taste aversion toward the novel taste, but not Ss in the control group. Post rotation nausea rating was affected marginally by conditioning, but rotation tolerance was not changed by conditioning. Hormone levels increased with rotation, but were unaffected by conditioning. Pavlovian conditioning of behavioral, but not of endocrine, indicators was effective in susceptible Ss using a rotating chair as US and a single CS-US pairing.
