Influence of sleep and wake on negative and neutral memory and valence in older adults and young adults. A, Average percent of correctly recognized target pictures (hit rate). B, Average inter-session change in valence ratings. Valence was rated on a 9-point Likert-type scale: 1=most negative, 5=neutral, 9=most positive. A positive change in valence indicates ratings became less negative. Error bars represent standard errors of means. Asterisks indicate significant (p<0.05) differences. Graphs on the right are adapted from Baran et al. (2012).
