Mean affective tone of segments across the remembered lifespan in (a) younger participants and (b) middle-aged and older participants. Note. Trend lines according to the age groups’ current age were included using the loess method (α = .5) as implemented in the R package ggplot2 (Wickham, 2016); 95% confidence intervals are displayed in grey. Age groups of younger participants vary in size because they comprise varying numbers of cohorts: n8yrs = 27, n12yrs = 54, n16yrs = 80, n20yrs = 105, n24yrs = 97, n28yrs = 66, n32yrs = 43, n36yrs = 22. Middle-aged and older participants: n40yrs = 28, n44yrs = 22, n48yrs = 20, n52yrs = 20, n65yrs = 30, n69yrs = 29, n73yrs = 28, n77yrs = 27
