| Abstract: | We assessed the propensity for false memories among patients with obstructive sleep apnoea syndrome (OSAS). Twenty-one patients with OSAS and 21 controls matched for sex, age and education were recruited. At encoding, an adaptation of the Deese-Roediger-McDermott paradigm was used to induce false memories. At retrieval, participants completed a forced-choice recognition task to distinguish memories based on verbatim traces from those based on gist traces. When the task encouraged retrieval based on either gist or verbatim traces, the groups performed similarly. However, when the task required retrieval based solely on verbatim traces, OSAS patients exhibited poor discrimination and produced more false memories. Our finding that OSAS leads to an increased propensity to produce false memories is discussed within the framework of both fuzzy-trace theory and activation-monitoring theory. |
