Grand-averaged ERPs from the pooled electrodes (Fz, FCz, Cz) is actually portrayed within the Fig
Due to the fact portrayed when you look at the Fig. step three, paired samples t-sample revealed that the stimuli before negativity (SPN) is actually a great deal more bad when users demonstrated personal appeal (?step 3.98 ± 0.70 ?V) in accordance with disinterest (?2.39 ± 0.56 ?V) within their price big date; t(step 1,24) = ?3.30, p = 0.003, Cohen’s d = ?0.66).
Prize positivity (RewP)
4a. We found a significant main effect of Feedback Valence (F(1,24) = 6.25, p = 0.020, ?p 2 = 0.21) and a significant main effect of Feedback Congruency (F(1,24) = , p 2 = 0.54), which were included in a significant interaction between Feedback Valence x Feedback Congruency (F(1,24) =, p = 0.001, ?p 2 = 0.37)). Follow-up paired samples t-test revealed that the RewP to the speed date’s feedback (7.54 ± 1.44 ?V) was significantly larger for Match outcomes relative to all other conditions (all ps Fig. 4
