In contrast, posterior (and middle) hippocampal encoding engagement showed a trend-level relationship with later true recognitions across age groups (effect of engagement: β=0.05, SE=0.03, Z = 1.81, p = 0.07) in a way that reliably varied by encoding condition (engagement × encoding condition interaction: β=0.06, SE=0.03, Z = 2.27, p = 0.02; no interactions with age group: both p > 0.77; Fig. 3 A ).
