Comparing attentional disengagement between prolific and MTurk samples
Open accessPublished version of a preprint
Abstract
Attention often disengages from primary tasks in favor of secondary tasks (i.e., multitasking) and task-unrelated thoughts (i.e., mind wandering). We assessed whether attentional disengagement, in the context of a cognitive task, can substantially differ between samples from commonly used online participant recruitment platforms, Prolific and Mechanical Turk (MTurk). Initially, eighty participants were recruited through Prolific to perform an attention task in which the risk of losing points for errors was varied (high risk = 80% chance of loss, low risk = 20% chance of loss). Attentional disengagement was measured via task performance along with self-reported mind wandering and multitasking. On Prolific, we observed surprisingly low levels of disengagement. We then conducted the same experiment on MTurk. Strikingly, MTurk participants exhibited more disengagement than Prolific participants. There was also an interaction between risk and platform, with the high-risk group exhibiting less disengagement, in terms of better task performance, than the low-risk group, but only on MTurk. Platform differences in individual traits related to disengagement and relations among study variables were also observed. Platform differences persisted, but were smaller, after increasing MTurk reputation criteria and remuneration in a second experiment. Therefore, recruitment platform and recruitment criteria could impact results related to attentional disengagement.

Prolific participants show higher attentiveness, longer and more appropriate completion times, fewer signs of disengagement, and greater response consistency.
“Prolific participants show higher attentiveness, longer and more appropriate completion times, fewer signs of disengagement, and greater response consistency (Albert and Smilek, 2023; Douglas et al., 2023).”
From Testing the testing effect on prolific: when retrieval practice fails to boost learning (2026) · cites this paper as Albert and Smilek, 2023
The Discussion reports greater mind wandering and multitasking and lower attention-task performance on MTurk than on Prolific, supporting the attentiveness and disengagement comparisons. But the Results (Demographics) report significantly longer completion times on MTurk, not Prolific, and do not establish that either platform’s times were more appropriate. The cited passages also do not establish greater response consistency among Prolific participants. (LLM, conf=0.91)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
