140 Deirdre Melvin 2.2 Participants 40 participants took part in the experiment. 18 males (mean age = 29.33, age range 21–39) and 22 females (mean age = 27.54, age range = 22–46). All participants had self reported normal hearing. Participants were recruited via the social media website, facebook.com. Once recruited, subsequent communication with partici-pants took place via E-Mail. Participants were instructed that if they discovered another participant also undertaking the test they should not discuss the experiment in advance of testing. They were also made aware that their names would remain anonymous and that their details would be strictly confidental. 18.2 % were still in education. Remaining participants had completed their education. The levels obtained ranged from post-16 vocational course (11.4 %), to postgraduate level degree level (45.5 %). The breakdown of those not in education self reported as: In full-time employment (40.9 %), in part-time employment (11.4 %), self employed (22.7 %), and unemployed 4.5 %. The favourite musicial genre for 90.9 % of the participants was rock / pop (including hiphop, RnB, metal, reggae etc.), followed by classical (6.8 %) and Jazz (2.3 %). Participants did not receive any payment for taking part. Written informed consent from all participants, and ethical approval, were obtained before testing. 2.3 Music Stimuli The music stimuli was collated using a previously established procedure.   Participants were contacted in advance of the experiment and asked to submit two pieces of music that consistently induced pleasure upon repeated listening without restrictions to the genre. The term ›Pleasurable‹ was not defined for the participants, instead they were advised to interpret the word for themselves. The music submissions of all the participants created an ecologically valid music stimuli database for use in the experiment (see appendices for complete list of musical stimuli). Each participant’s selected music was used as the remaining participants emotionally neutral control. The music stimuli may have been pleasurable or neutral to all participants but the experimenter anticipated a pleasurable response from the individual participant when presented with the music they submitted. For the music stimuli that was not selected by the participant a neutral or pleasurable response was predicted. In this way, the experimenter hoped to use music type (pleasurable, neutral) to replicate the face type condition distinguishing neutral and attractive faces in the original study.   At the time of submission participants were asked to identify a section for each piece of music submitted, that in their opinion, triggered recognition of the track. They were not informed of why this information was required. The recognition time was used to edit the musical stimuli to 0’40” for the keypress task and 0’10” for the ratings task.
