Thirty-three participants took part in the experiment in exchange for a monetary reward of €7—from which three participants were excluded from analysis. One based on their many no-response trials (80%) and two for a lack of deceitful trials (0 and 0.02%, respectively). The data from thirty participants with normal or corrected-to-normal vision was used for analysis (Rangeage: 19–58, Mage: 29.7 SDage: 10.1, 17 Female). Participants were recruited by using a mailing list consisting of volunteers.
The experiment was presented on a laptop (Dell Latitude 3380, with a 13.3 inch LCD monitor) and used OpenSesame for stimulus presentation, while heart rate and skin conductance measures were taken (Mathôt et al., 2012 (link)). Skin conductance measures were taken with two 13 mm diameter silver chloride skin electrodes that were attached to the middle phalanges, on the palmar aspect of participants' index and middle fingers, which were in turn connected to a galvanic skin response module. A heart rate sensor was attached to participants' ring fingers. The skin electrodes and heart rate sensor were connected to a Brain Products V-Amp 8 channel amplifier, sampling at 500 Hz. Event triggers for each trial were sent from the laptop to the amplifier via a Brain Products TriggerBox. Participants' distance from the screen was 80 cm.
