(A) The probability that the probed item was stored in memory over the delay (α) as a function of State and Delay. (B) The inverse precision of the stored representations (σ; a higher number reflects lower precision) as a function of the same. Error bars represent 95% confidence intervals based on within-subject standard error.59,60 SD, sleep deprivation; RW, rested wakefulness.
