Recent studies have empirically validated the data obtained from Amazon’s Mechanical Turk.

Amazon’s Mechanical Turk workers behaved similarly not only in simple surveys but also in tasks

used in cognitive behavioral experiments that employ multiple trials and require

continuous attention to the task. The present study aimed to extend these findings

to data from Japanese crowdsourcing pool in which participants have different

ethnic backgrounds from Amazon’s Mechanical Turk workers. In five cognitive

experiments, such as the Stroop and Flanker experiments, the reaction times and

error rates of Japanese crowdsourcing workers and those of university students

were compared and contrasted. The results were consistent with those of previous

studies, although the students responded more quickly and poorly than the workers.

These findings suggested that the Japanese crowdsourcing sample is another eligible participant

pool in behavioral research; however, further investigations are needed to

address issues of qualitative differences between student and worker samples.
