Title: The Feasibility of a Japanese Crowdsourcing Service for Experimental Research in Psychology
Journal(書誌情報）: SAGE Open, 7(1), 2017.
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.
