Experiment 1

Method

Participant

Twenty-six volunteers participated in Experiment 1 (14 females and 12 males, ranging in age from 18 to 26 years, with a mean of 20.8 years and a standard deviation of 2.17 years). All participants were right-handed, with normal or corrected-to-normal color vision. We excluded two participants for their large response variability (see the section "Data Analysis") and reported the results from the rest 24 participants. We chose the sample size by referencing prior studies \cite{Bae2020,Fischer2014}, which often identify significant effects (Cohen’s d > 0.753). Participants signed the informed consent form before the experiment commenced and received compensation at a rate of 9 Euros/hour compensation. The study was approved by the ethics committees of the Psychology Department at LMU Munich.
