Participants
Thirty right-handed volunteers (16 females and 14 males, mean age 23.9 ±
2.3 and 24.6 ± 2.8 respectively) took part to this study. Most of the
participants were undergraduate students at the Department of Psychology
(University of Turin) and were recruited from a participants’ database
or through flyers posted on the University website. All experimental
subjects gave written informed consent to participate, which was
approved by the local ethics committee and performed in accordance with
the Declaration of Helsinki. At the end of the experiment, all
participants were informed about the aims and the scopes of the
experiment and did not receive any compensation for participation in
this research study.
