Testing location The study will be conducted within 6 adjacent cubicles in the psychology suite at Stirling University. Each cubicle contains a desk and chair and is equipped with a PC. The students will be tested in groups of 6. The experimenter will be positioned in the adjoining hallway allowing the students to hear/receive instructions simultaneously. Students will able to hear the experimenter but will not be able to see or hear each other when responding or when viewing stimuli. Images of the lab and cubicles will be provided. We have elected to present stimuli via PC to enhance control of timing while maintain separation of participants. We will use Lenovo 32 bit PCs running on Windows 7. The video will be shown using the Windows media Player and the line-up image will be shown in Irfanview. During the video presentation participants will be asked to wear digital stereo headphones. We will request that participants record hard copies of their responses – making it easier for us to ensure that all relevant information has been provided. Digital copies will subsequently be recorded and posted with the data on Open Science Framework.
