    • Sleep physiology predicts memory retention after reactivation

      Macdonald, Kevin J.; Cote, Kimberly A. (Wiley, 2016)
      Both sleep and future relevance influence memory consolidation; however, limited research has investigated their role in memory reconsolidation. We manipulated the future relevance of both stable and labile memories in need of reconsolidation. Two groups learned two blocks of syllable pairs on one evening and were told they would be tested on one of the blocks later. On the second evening, one group (Labile) received reminders designed to return their memories of syllable pairs to a labile state, while a second group (Stable) received reminders designed to leave these memories in a stable state. No significant differences in memory retention were found between blocks or groups the following morning. Frontal delta (0.5–4 Hz) electroencephalographic power during Stage 2 sleep correlated positively with retention of future-relevant material exclusively in the Labile group. Central theta (4–8 Hz) electroencephalographic power during rapid eye movement (REM) sleep correlated positively with the extent to which the Labile group selectively retained future-relevant material. These relationships suggest that sleep-dependent processes are involved in an economical reprocessing of memories beyond the initial stages of consolidation.
    • Event-Related Neural Response to Emotional Picture Stimuli Following Sleep Deprivation

      Cote, Kimberly; Jancsar, Cara; Hunt, Bryce (American Psychological Association, 2015)
      The impact of sleep deprivation on various stages of information processing was investigated during a valance categorization picture task using temporally sensitive event-related potentials (ERPs). Young, healthy, good sleepers were randomly assigned to a total sleep deprivation (n = 22) or sleep control group (n = 23). Picture stimuli were presented at random for 1000 ms and rated as very-positive, slightly positive, slightly negative, or very-negative. ERP measures included a parietal-occipital positive peak (P1) reflecting early sensory processing and “reactivity,” and a central-parietal Late Positive Potential (LPP) peak indexing sustained attention toward stimuli. There was a significant Group-by-Valance interaction for LPP amplitude; sleep-deprived participants had a larger LPP than controls to positive and negative, but not neutral pictures. Both groups had larger LPPs to positive and negative pictures relative to neutral pictures, but only the sleep-deprived group had a larger LPP to negative compared with positive stimuli. Sleep-deprived individuals with a lower reappraisal strategy in emotion regulation style produced a relatively larger LPP response to negative pictures. In conclusion, sleep deprivation did not influence early sensory processing or attention capture but led to greater sustained allocation of attention toward emotional pictures, particularly negative stimuli. Enhanced attention toward emotional stimuli may result in failure to attend to other relevant information and poor decision making, and may be especially problematic for individuals with lower emotion reappraisal strategies.
