Table 2.

Unadjusted and adjusted negative binomial mixed models testing the effect of gender, age group, condition (whether words were learnt in relation to the self or another person) and valence (whether words were positive or negative) on the total number of hits.

Note. All models adjusted for condition and valence. Fully adjusted models also adjusted for continuous age within each age group, school, testing group size, non-verbal IQ score, and positive and negative false alarms. For gender, male was the reference group. For condition, other-referential was the reference group. For valence, positive was the reference group.
