Skin conductance was measured during acquisition training via two reusable Ag/AgCl electrodes attached to the hypothenar eminence of the participants’ non-mouse hand and a V-Amp 16 amplifier (Brain Products GmbH, Gilching, Germany). The sampling rate was set to 1000 Hz. Data preprocessing was conducted using BrainVision Analyzer 2 software (Brain Products GmbH, Gilching, Germany). Raw data were filtered with a 50 Hz notch filter and a 1 Hz low-pass filter. SCR amplitudes were obtained by semi-manual trough-to-peak scoring. Negative SCRs were set to zero and included in the analyses. Amplitudes were then square root transformed to reduce skewness. Two participants of the neutral learning group had to be excluded from SCR analysis due to poor signal quality.
