The effects of sleep deprivation on item and associative recognition memory.

摘要: Sleep deprivation adversely affects the ability to perform cognitive tasks, but theories range from predicting an overall decline in functioning because of reduced stability attentional networks specific deficits various domains or processes. We measured effects sleep on two memory item recognition ("was this word list studied") and associative ("were these words studied same pair"). These tasks test for information encoded a few minutes earlier so do not address working consolidation after sleep. A diffusion model was used decompose accuracy response time distributions produce parameter estimates components processing. The assumes that over time, noisy evidence task stimulus is accumulated one decision criteria, parameters governing process are extracted interpreted terms distinct Results showed reduces drift rate (evidence process), with little effect other process. results contrast aging, which show large declines recognition. suggest degrades quality stored may occur through degraded (PsycINFO Database Record
