Factors During Encoding and Sleep That Promote Memory Persistence

In this talk, I will investigate how long-term memory is modulated by reactivation during sleep and affective states at encoding. First, I will focus on a technique that involves presenting learning-related stimuli during sleep (termed targeted memory reactivation, or TMR). My findings show that TMR benefits memory retention for numerous types of memory. Crucially, they also point to a specific physiological process - the sleep spindle - that is crucial for optimal memory reactivation during sleep.

Towards The Neural Correlates And Functions Of Perceptual Confidence

Perceptual confidence refers to a subjective estimate of the uncertainty of a perceptual decision. Intuitively, we might feel as though a perceptual experience is clear or unclear and have, respectively, high or low confidence in decisions based on those experiences. But what is the relationship between the accuracy of our perceptual decisions and our confidence in them? What, if anything, does the subjective confidence we ascribe to a choice mean for subsequent behavior?
