2.1.1. Participants
Three-hundred-and-five individuals (131 females), whose age ranged from 18 to 88 years (M = 33.4 years, SD = 11.9), were recruited from Amazon’s Mechanical Turk to take part in Experiment 1 in return for a payment of 0.30 US dollars. Only those living in the United States of America were able to take part in the study. The experiment was conducted on 21/09/2014, from 18:00 GMT onwards, and over a three-hour period (see Woods, Velasco, Levitan, Wan, & Spence, 2015, for a methodological overview of internet-based research). The participants took an average of 156 s (SD = 117 s) to complete the study. All of the participants provided their informed consent prior to taking part. The experiment was reviewed and approved by the Central University Research Ethics Committee at the University of Oxford
