There were 200 buy T-5224 trials in total, and participants had been allowed to take a break when necessary. Since the process was identical for participants from both cultural groups, the pretesting phase was not important towards the cultural distinction question we had been keen on. Inside the testing phase (Figure 1), participants completed the sound comparison activity. In every trial, participants very first heard the normal tone. Right after a jittered interval of 800?200 ms, they heard a comparison tone after which created a judgment which tone was louder by pressing button `F' (if the initial one particular is louder) or `J' (if the second one is louder) on the keyboard with their left hand. The intensity of comparison tones was randomized across trials. There had been three circumstances inside the testing phase that differed in the way the typical tone was triggered. In `self ' situation, the regular tone followed right away immediately after participants pressing the button `2' with their correct hand as within the pretesting phase. They had been asked to press the button about when each three s after a response was made for the earlier trial. No feedback of press latency was offered. In `other' situation, the normal tone was triggered by the experimenter pressing the button `2' with ideal hand within the similar way as participants did in `self ' condition. Participants have been needed to pay interest for the experimenter's hand within the complete method. In `computer' situation, the laptop or computer controlled the presentation with the typical tone and participants received visual cues (from 1 s prior to the onset of common tone,Frontiers in Psychology | www.frontiersin.orgDecember 2015 | Volume six | ArticleCao and GrossSelf and Sounds Generated by OthersFIGURE 1 | Schematic illustration of a standard trial. The typical tone was triggered by participant (`self' condition), experimenter (`other' condition), or laptop or computer (`computer' situation). The comparison tone played automatically soon after an SOA of 800?200 ms. Participants had been instructed to respond as accurately as possible which tone was louder. All tones (1000 Hz, one hundred ms in duration, ten ms rise/fall ramp, sampling price at 48000 Hz) had been generated with MATLAB (http://www.mathworks.com). The experiment consisted of a pretesting phase plus a testing phase. Inside the pretesting phase, participants pressed a button (number `2' on numeric section of a typical keyboard) with their appropriate index finger about as soon as each and every 3 s. Soon after a button press, they heard a regular tone immediately and received visual feedback on the screen no matter if the response was excellent, too slow (more than 3.8 s following final response) or as well speedy (much less than two.2 s immediately after final response). There had been 200 trials in total, and participants had been permitted to take a break when required. The objective of such as this pretesting phase was to keep the process the exact same as the procedure used in Sato (2008). Since the procedure was identical for participants from both cultural groups, the pretesting phase was not critical towards the cultural difference question we have been enthusiastic about. In the testing phase (Figure 1), participants completed the sound comparison activity. In every single trial, participants first heard the standard tone.
