TLDR
The authors presented new demographic data about the Mechanical Turk subject population, reviewed the strengths of Mechanical Turk relative to other online and offline methods of recruiting subjects, and compared the magnitude of effects obtained using Mechanical Turk and traditional subject pools.Abstract:
Although Mechanical Turk has recently become popular among social scientists as a source of experimental data, doubts may linger about the quality of data provided by subjects recruited from online labor markets. We address these potential concerns by presenting new demographic data about the Mechanical Turk subject population, reviewing the strengths of Mechanical Turk relative to other online and offline methods of recruiting subjects, and comparing the magnitude of effects obtained using Mechanical Turk and traditional subject pools. We further discuss some additional benefits such as the possibility of longitudinal, cross cultural and prescreening designs, and offer some advice on how to best manage a common subject pool.read more

Comparing Amazon’s Mechanical Turk Platform to Conventional Data Collection Methods in the Health and Medical Research Literature
TL;DR: The literature overwhelmingly concludes that MTurk is an efficient, reliable, cost-effective tool for generating sample responses that are largely comparable to those collected via more conventional means.

What Motivates Effort?: Evidence and Expert Forecasts
Stefano DellaVigna,Devin G. Pope +1 more
TL;DR: The authors conducted a large-scale real-effort experiment with eighteen treatment arms and found that monetary incentives work largely as expected, including a very low piece rate treatment which does not crowd out effort; the evidence is partly consistent with standard behavioural models, including warm glow, though they do not find evidence of probability weighting; and the psychological motivators are effective but less so than incentives.

Large-scale analysis of test–retest reliabilities of self-regulation measures
A. Zeynep Enkavi,Ian W. Eisenberg,Patrick G. Bissett,Gina L. Mazza,David P. MacKinnon,Lisa A. Marsch,Russell A. Poldrack +6 more
TL;DR: It is found that dependent variables from self-report surveys of self-regulation have high test–retest reliability, while DVs derived from behavioral tasks do not, and it is confirmed that this is due to differences in between-subject variability.

Gender differences in evaluation of new business opportunity: A stereotype threat perspective
TL;DR: The authors explored differences between men and women on evaluation of new business opportunities and found that men reported higher opportunity evaluation than women when no gender stereotypical information was presented, whereas women evaluated the business opportunity equally favorably when entrepreneurs were described using gender-neutral attributes.

The Framing of Decisions and the Psychology of Choice
Amos Tversky,Daniel Kahneman +1 more
TL;DR: The psychological principles that govern the perception of decision problems and the evaluation of probabilities and outcomes produce predictable shifts of preference when the same problem is framed in different ways.

Amazon's Mechanical Turk A New Source of Inexpensive, Yet High-Quality, Data?
TL;DR: Findings indicate that MTurk can be used to obtain high-quality data inexpensively and rapidly and the data obtained are at least as reliable as those obtained via traditional methods.
Journal ArticleDOI
On the social psychology of the psychological experiment: With particular reference to demand characteristics and their implications.
TL;DR: In this paper, the authors focus on some of the qualities peculiar to psychological experiments and point out that the demand characteristics perceived in any particular experiment will vary with the sophistication, intelligence, and previous experience of each experimental subject.

Extensional versus intuitive reasoning: The conjunction fallacy in probability judgment.
Amos Tversky,Daniel Kahneman +1 more
TL;DR: The conjunction rule as mentioned in this paper states that the probability of a conjunction cannot exceed the probabilities of its constituents, P (A) and P (B), because the extension (or the possibility set) of the conjunction is included in the extension of their constituents.

Should we trust web-based studies? A comparative analysis of six preconceptions about internet questionnaires.
TL;DR: Internet data collection methods, with a focus on self-report questionnaires from self-selected samples, are evaluated and compared with traditional paper-and-pencil methods and it is concluded that Internet methods can contribute to many areas of psychology.
