In two studies, we investigated the degree to which action primes, and acting upon those primes affect agency ratings. Participants performed left or right button-presses that generated tones, and were subsequently asked to indicate the degree to which they felt that they, instead of the computer, had caused the tones. Prior to button-presses, participants were subliminally or supraliminally primed with "left" or "right". Participants were free to press either button, and thus could perform prime-compatible or prime-incompatible actions. Results showed that incompatible subliminal primes lowered sense of agency compared to the effects of subliminal compatible primes. In contrast, supraliminal compatible primes lowered agency compared to inc...
