Implicit memory for the content but not the speaker of sleep-played messages

Ruch, Simon; Zäske, Romi; Züst, Marc Alain; Schweinberger, Stefan Robert; Henke, Katharina (31 March 2016). Implicit memory for the content but not the speaker of sleep-played messages (Unpublished). In: 11th Annual Meeting Clinical Neuroscience Bern (CNB). Bern, Switzerland. 31.03.2016.

We presented 28 sentences uttered by 28 unfamiliar speakers to sleeping participants to investigate whether humans can encode new verbal messages, learn voices of unfamiliar speakers, and form associations between speakers and messages during EEG-defined deep sleep. After waking, participants performed three tests which assessed the unconscious recognition of sleep-played speakers, messages, and speaker-message associations. Recognition performance in all tests was at chance level. However, response latencies revealed implicit memory for sleep-played messages but neither for speakers nor for speaker-message combinations. Only participants with excellent implicit memory for sleep-played messages also displayed implicit memory for speakers but not speaker-message associations. Hence, deep sleep allows for the semantic encoding of novel verbal messages.
