Semantic-to-autobiographical memory priming occurs when stimuli are presented below the threshold of awareness

A number of studies have now shown that general information processing causes the activation of memories in the autobiographical memory system. These studies have shown that general processing of words, sounds, objects, or pictures primes autobiographical memories on voluntary and involuntary autobiographical memory tasks (the Crovitz cue-word task and the vigilance task). Deemed semantic-to-autobiographical memory priming, our goal in the current study was to demonstrate that this form of priming causes the unconscious activation of autobiographical memories (autobiographical automaticity) at the point of priming. Participants named words under subliminal and supraliminal conditions and then received a test of priming (the vigilance task). The results showed that words that were processed below the threshold of awareness were equally likely as words processed above the threshold of awareness to prime the production of involuntary autobiographical memories on the vigilance task. The results support the idea that autobiographical memory activations in semantic-to-autobiographical priming is both unintentional and unconscious.
