Amazon Mechanical Turk

Antonio A Arechar, Gordon Kraft-Todd, David G Rand
Online experiments allow researchers to collect datasets at times not typical of laboratory studies. We recruit 2,336 participants from Amazon Mechanical Turk to examine if participant characteristics and behaviors differ depending on whether the experiment is conducted during the day versus night, and on weekdays versus weekends. Participants make incentivized decisions involving prosociality, punishment, and discounting, and complete a demographic and personality survey. We find no time or day differences in behavior, but do find that participants at nights and on weekends are less experienced with online studies; on weekends are less reflective; and at night are less conscientious and more neurotic...

INTRODUCTION: Cost-utility analyses (CUA) are useful when the treatment conditions depend on patient preferences that are in turn dependent on health state utility value. Spina bifida (SB) is an example of such a preference-sensitive condition. Historically, the SB utility value for CUA has been gathered via a traditional face-to-face interview. However, due to funding and time constrains, utility estimation via online crowdsourcing has recently gained popularity. Our aim was to estimate the utility value for a generic SB health state using a validated online tool...

BACKGROUND: The seductive allure of neuroscience explanations (SANE) is the finding that people overweight psychological arguments when framed in terms of neuroscience findings. AIM: This study extended this finding to arguments concerning the application of psychological findings to educational topics. SAMPLE: Participants (n = 320) were recruited from the general public, specifically among English-speaking Amazon Mechanical Turk workers residing in the United States...

In judging normalcy, surgeons rely on established facial anthropometric measures and proportions. However, there exists a range of "normal," and a degree of disproportion may be considered more attractive. The authors set out to determine how changes in only intercanthal distance affect the layperson's perception of beauty and personality traits of a face. The authors used's Mechanical Turk (MTurk), a crowdsourcing tool, to determine how changes in intercanthal distance affect overall perception of beauty and personality...

BACKGROUND: The effects of orthognathic surgery go beyond objective cephalometric correction of facial and dental disproportion and malocclusion, respectively. The authors hypothesized that there is tangible improvement following surgery that alters publicly perceived personality traits and emotions. METHODS: The authors used's Mechanical Turk (MTurk), a crowdsourcing tool, to determine how preoperative and postoperative images of orthognathic surgery patients were perceived on six personality traits and six emotional expressions based on posteroanterior and lateral photographs...

For individuals with a chronic illness, such as type 2 diabetes, a multitude of factors may influence the ways people cope with their condition. This study compares characteristics of the illness and characteristics of a patient's romantic relationship as factors that predict coping behaviors for individuals with type 2 diabetes. Specifically, we identify illness uncertainty as a feature of chronic illness, as well as relational uncertainty and interference from partners as relationship characteristics that are associated with coping behaviors...

This paper addresses the key assumption in behavioral and transportation planning literature that, when people use a transit system more frequently, they become less dependent on and less sensitive to transit maps in their decision-making. Therefore, according to this assumption, map changes are much less impactful to travel decisions of frequent riders than to that of first-time or new passengers. This assumption-though never empirically validated-has been the major hurdle for transit maps to becoming a planning tool to change passengers' behavior...

Self-regulation is a broad construct representing the general ability to recruit cognitive, motivational and emotional resources to achieve long-term goals. This construct has been implicated in a host of health-risk behaviors, and is a promising target for fostering beneficial behavior change. Despite its clear importance, the behavioral, psychological and neural components of self-regulation remain poorly understood, which contributes to theoretical inconsistencies and hinders maximally effective intervention development...

Text simplification often relies on dated, unproven readability formulas. As an alternative and motivated by the success of term familiarity, we test a complementary measure: grammar familiarity. Grammar familiarity is measured as the frequency of the 3(rd) level sentence parse tree and is useful for evaluating individual sentences. We created a database of 140K unique 3(rd) level parse structures by parsing and binning all 5.4M sentences in English Wikipedia. We then calculated the grammar frequencies across the corpus and created 11 frequency bins...

The aim of the current study was to create a new measure of parenting practices, constituted by items from already established measures, to advance the measurement of parenting practices in clinical and research settings. Five stages were utilized to select optimal parenting items, establish a factor structure consisting of positive and negative dimensions of parenting, meaningfully consider child developmental stage, and ensure strong psychometric properties (reliability and validity) of the final measure...

Despite real-world implications, the pattern of delay discounting in alcohol users when the commodities now and later differ has not been well characterized. In this study, 60 participants on Amazon's Mechanical Turk completed the Alcohol Use Disorder Identification Test (AUDIT) to assess severity of use and completed four delay discounting tasks between hypothetical, equivalent amounts of alcohol and money available at five delays. The tasks included two cross-commodity (alcohol now-money later and money now-alcohol later) and two same-commodity (money now-money later and alcohol now-alcohol later) conditions...

Public attitudes on homelessness can and has influenced policies and services for homeless populations. This study surveyed national public attitudes about homelessness in the 21st century and examined changes in attitudes in the past two decades. An online survey of public attitudes about homelessness was conducted with 541 U.S. adults across 47 states in November 2016 using Amazon Mechanical Turk. Survey results were compared to two public surveys conducted in 1990. Compared to previous surveys, the current sample endorsed more compassion, government support, and liberal attitudes about homelessness...

Common mental health consequences following the experience of potentially traumatic events include Posttraumatic Stress Disorder (PTSD) and addictive behaviors. Problematic smartphone use is a newer manifestation of addictive behaviors. People with anxiety severity (such as PTSD) may be at risk for problematic smartphone use as a means of coping with their symptoms. Unique to our knowledge, we assessed relations between PTSD symptom clusters and problematic smartphone use. Participants (N = 347), recruited through Amazon's Mechanical Turk (MTurk), completed measures of PTSD and smartphone addiction...

BACKGROUND: The involvement of patients in research better aligns evidence generation to the gaps that patients themselves face when making decisions about health care. However, obtaining patients' perspectives is challenging. Amazon's Mechanical Turk (MTurk) has gained popularity over the past decade as a crowdsourcing platform to reach large numbers of individuals to perform tasks for a small reward for the respondent, at small cost to the investigator. The appropriateness of such crowdsourcing methods in medical research has yet to be clarified...

Crowdsourcing is "the practice of obtaining participants, services, ideas, or content by soliciting contributions from a large group of people, especially via the Internet." (Ranard et al. J. Gen. Intern. Med. 29:187, 2014) Although crowdsourcing has been adopted in healthcare research and its potential for analyzing large datasets and obtaining rapid feedback has recently been recognized, no systematic reviews of crowdsourcing in cancer research have been conducted. Therefore, we sought to identify applications of and explore potential uses for crowdsourcing in cancer research...

BACKGROUND: Visual alcohol cues are often used to elicit craving (e.g., cue-reactivity), and selection of appropriate comparison cues is important to isolate the specific effect of craving for alcohol. OBJECTIVES: In the current study, via the development of a new set of non-alcoholic beverage cues, we examine measurement and methodological choices in testing alcohol images for cue-reactivity studies. METHODS: The current project combined two independent studies of hazardous (Study 1; n = 80) and recent drinkers (Study 2; n = 244) recruited from Amazon Mechanical Turk...

Backround: Increasing use of genetic technologies in clinical and research settings increases the potential for misattributed paternity to be identified. Yet existing guidance from the President's Commission for the Study of Ethical Problems in Biomedical and Behavioral Research and the Institute of Medicine (amongst others) offers contradictory advice. Genetic health professionals are thus likely to vary in their practice when misattributed paternity is identified, and empirical investigation into the disclosure of misattributed paternity is scarce...
