Trace fear memory recall: preregistered analyses
LME, memory retention
SECONDARY
Our preregistered primary outcome measure for trace fear memory retention was fear-potentiated startle, quantified by SEBR. A direct group comparison, our preregistered primary analysis, revealed no significant difference between doxycycline and placebo (Our preregistered secondary outcome measure of trace fear retention was SCR. In our preregistered LME analysis, we found a significant effect of trial, suggesting habituation. There were no other significant effects after Holm–Bonferroni correction for the three time points (see LME analysis of SCR during trace fear recallModels are estimated with lme4, lmer(data ∼ (1+trial|subject) + group*condition*trial) for CS and US time point and lmer(data ∼ (1|subject) + group*condition*trial) for trace interval, significant (
