Changes in memory specificity from pre- to post-intervention
A repeated measures ANOVA was conducted on the total number of specific memories on the AMT (across both remoteness conditions) with time (pre- and post-intervention) as a within-subjects factor, and group (LKM, colouring) as a between-subjects factor. An analysis of residuals confirmed the assumptions of linearity. Results revealed a main effect of time, F(1, 48) = 4.73, A Bayesian repeated measures ANOVA was then performed on the number of specific memories in the free-recall condition using remoteness (recent and remote) and time (pre- and post-intervention) as within-subjects factors, and group (LKM, colouring) as between-subjects factors. An analysis of residuals confirmed the assumptions of linearity. Results revealed no main effect of time, BF10 = 0.17, while results were inconclusive regarding a main effect of remoteness, BF10 = 0.64, and group, BF10 = 0.90. Results were further inconclusive regarding an interaction between time and group, BF10 = 0.99 and remoteness and group, BF10 = 1.75, while there was no interaction between time, remoteness, and group, BF10 = 0.14. Reliable conclusions could not be drawn regarding group differences in a change in specificity over time in the free-recall condition.Moreover, to examine whether specificity increased over time in remote memories in the remote condition, a Bayesian repeated measures ANOVA was performed on the number of specific memories using time (pre- and post-intervention) as a within-subjects factor, and group (LKM, colouring) as a between-subjects factor. There was no main effect of time, BF10 = 0.23, while results were inconclusive regarding group, BF10 = 1.19, and regarding an interaction between time and group, BF10 = 0.84. Results demonstrated that specificity of remote memories (in the remote condition) was not significantly altered over time, while reliable conclusions could not be drawn regarding group differences in a change in retrieval of remote specific memories.
