An extended abstract by Lukosius and Hyman suggests that increased payment causes studies to be done more quickly (not surprising). They also checked for attention and divided the group into attentive and non attentive respondents. They defined about 20% of ‘inattentive’.
Remuneration of the tested amounts (i.e., $0.50, $0.75, and $ 1.00) did not affect data
quality except for data collection pace. Roughly 20% of respondents were inattentive. In terms of
motivation, attentive respondents, relative to non-attentive respondents, more enjoyed participation, put more effort into answering, and were more confident in their answers.
I haven’t seen the whole study, so I’m not sure how long it took, but it is worth noting that these researchers paid pretty well (assuming it is a 405 minute study, which could be a completely false assumption).
