Studies of the online experiment revealed that web-based cognitive experiment, which has Western crowd-workers (CW) as participants, replicated a task-specific effect that was shown in a conventional lab-based study (Crump et al., 2013). While a study compared Japanese CW and students showed that CW responded more accurately but more slowly than students (Majima, 2017). The present study compared the performance of in cognitive behavioral tasks between Japanese CW and students to reveal whether the speed-accuracy trade-off is replicated as in the Majima (2017), and whether the task-specific effect is replicated in a memory-task and a mood-induction task. We presented a Flanker task, a mental rotation task, levels of processing task and a mood-induction task. The results showed task-specific effects were replicated in all tasks and found no speed-accuracy trade-off. This might suggest that web-based experiments with Japanese CW is eligible participants pool in cognitive research as in lab-based experiment with students.
