Similarly, peak amplitudes extracted 0–80 ms post R-wave from ECG and uncorrected frontal-central electrodes did not differ significantly between experimental conditions, although ECG amplitudes showed a trend towards a main effect of valence F(1,23) = 3.17, p = 0.092 ( BF 10 = 2.2 provides anecdotal evidence for H A ) (all other p s > 0.27; BF 10 < 0.14 offering substantial evidence for H 0 ).

Findings from experiment 2 thus produce a repetition suppression effect for the repeated negative stimuli while replicating the repetition enhancement to repeating neutral stimuli observed in experiment 1. Similar to experiment 1, the correlation between absolute HEP amplitude (collapsed across all conditions) and heartbeat tracking score failed to reach significance ( ρ = −0.09, p = 0.7).
