Crowdsourcing is a newer labor portal where anonymous workers earn small amount of money for completing Web-based tasks. Recent research investigating human behavior often recruit workers through these platforms to ask them to participate in online survey and experiment. To make it short, the advantage of crowdsourcing is that it enables researchers to collect empirical data at relatively lower economical, human,and temporal costs. However, it is also known that some professional survey takers who repeatedly participated in academic survey tasks are likely to show satisficing —behavior in which workers do not pay attention adequately to research materials. In addition, internet-based research practice has other concerns specific to ethical consideration in online data collection, including presenting proper post-survey debriefing and maintaining ethical level of compensation. Present article outlined a state of the art of internet-based research in the domain of social sciences, indicated both strong and weak point of the online study, and suggested possible future direction in cognitive studies with crowdsourcing.
