Testing infants in the laboratory is expensive in time and money; consequently, many studies are underpowered, reducing their reproducibility. We investigated whether the online platform, Amazon Mechanical Turk (MTurk), could be used as a resource to more easily recruit and measure the behavior of infant populations. Using a looking time paradigm, with users' webcams we recorded how long infants aged 5 to 8months attended while viewing children's television programs. We found that infants (N=57) were more reliably engaged by some movies than by others and that the most engaging movies could maintain attention for approximately 70% of a 10- to 13-min period...

Jennifer Wu, Philipp Kraemer
This study examined preferences and ascriptions of human control for avatars associated with positive and negative language. An avatar is a graphical representation of an individual user in a virtual world. Users form judgments of other virtual world users based on the appearance and behavior of their avatars in the absence of physical cues. In particular, users have previously displayed sensitivity toward anthropomorphism and verbal behavior of avatars they encounter within virtual environments. Thus far, investigations of language in online and virtual spaces have been limited to specific contexts...

Lawrence P Behmer, Matthew J C Crump
We show that theories of response scheduling for sequential action can be discriminated on the basis of their predictions for the dynamic range of response set activation during sequencing, which refers to the momentary span of activation states for completed and to-be-completed actions in a response set. In particular, theories allow that future actions in a plan are partially activated, but differ with respect to the width of the range, which refers to the number of future actions that are partially activated...

This article presents the development and psychometric evaluation of the Internalized Racism in Asian Americans Scale (IRAAS), which was designed to measure the degree to which Asian Americans internalized hostile attitudes and negative messages targeted toward their racial identity. Items were developed on basis of prior literature, vetted through expert feedback and cognitive interviews, and administered to 655 Asian American participants through Amazon Mechanical Turk. Exploratory factor analysis with a random subsample (n = 324) yielded a psychometrically robust preliminary measurement model consisting of 3 factors: Self-Negativity, Weakness Stereotypes, and Appearance Bias...

OBJECTIVE: This study examined the relationship between mindful feeding as a novel construct and parent-reported child dietary intake. METHODS: Participants (N=497) were parents of children ages 2.9 to 7.5 recruited through Amazon Mechanical Turk (MTurk). Parents were primarily non-Hispanic white (79%) and female (76%). Simple and hierarchical regression analyses were conducted to examine the associations between parental mindful feeding (i.e., parent mental and emotional presence while feeding a child) and their children's dietary intake...

The purpose of the current study was two-fold: (1) To examine time trends of the inclusion of fathers in child psychopathology research from 2005 to 2015; and (2) to examine online crowdsourcing as a method to recruit and study fathers. In study 1, findings indicated that, relative to two earlier reviews of father participation from 1984 to 1991 and 1992-2004, there has been limited progress in the inclusion of fathers in child psychopathology research over the last decade. In study 2, without explicit efforts to recruit fathers, almost 40% of a sample of 564 parents recruited from online crowdsourcing (Amazon's Mechanical Turk) were fathers...

The use of crowdsourcing platforms such as Amazon's Mechanical Turk (MTurk) for data collection in the behavioral sciences has increased substantially in the past several years due in large part to (a) the ability to recruit large samples, (b) the inexpensiveness of data collection, (c) the speed of data collection, and (d) evidence that the data collected are, for the most part, of equal or better quality to that collected in undergraduate research pools. In this review, we first evaluate the strengths and potential limitations of this approach to data collection...

OBJECTIVE: Personality traits are associated with well-being, but the precise correlates vary across well-being dimensions and within each Big Five domain. This study is the first to examine the unique associations between the Big Five aspects (rather than facets) and multiple well-being dimensions. METHOD: Two samples of U.S. participants (Total N = 706, Mage = 36.17, 54% female) recruited via Amazon's Mechanical Turk completed measures of the Big Five aspects and subjective, psychological, and PERMA well-being...

INTRODUCTION: Warning labels for cigarettes proposed by Food and Drug Administration (FDA) were rejected by the courts partly because they were thought to be emotionally evocative but have no educational value. To address this issue, we compared three types of smoking warnings: (1) FDA-proposed warnings with pictures illustrating the smoking hazards; (2) warnings with the same text information paired with equally aversive but smoking-irrelevant images; and (3) text-only warnings. METHODS: Smokers recruited through Amazon's Mechanical Turk were randomly assigned to one of the three conditions...

This study tested the effect of temporal framing on young adult smokers' response to antismoking communication messages. In two studies using largely identical designs, young adult smokers recruited from a large university (n = 52) and Amazon Mechanical Turk (n = 210) were exposed to either no messages or messages featuring different temporal frames. Analysis of the combined data (N = 262) showed that framing the health consequences of smoking in a proximal (vs. distal) time frame led to greater perceived message relevance, less use of heuristic processing, greater use of systematic processing, greater positive affect, and more intense fear...

INTRODUCTION: While diagnostic testing is common in the emergency department, the value of some testing is questionable. The purpose of this study was to assess how varying levels of benefit, risk, and costs influenced an individual's desire to have diagnostic testing. METHODS: A survey through Amazon Mechanical Turk presented hypothetical clinical situations: low risk chest pain and minor traumatic brain injury. Each scenario included three given variables (benefit, risk, and cost), that was independently randomly varied over four possible values (0...

BACKGROUND: Existing instruments that assess individuals' relationships with mobile phones tend to focus on negative constructs such as addiction or dependence, and appear to assume that high mobile phone use reflects pathology. Mobile phones can be beneficial for health behavior change, disease management, work productivity, and social connections, so there is a need for an instrument that provides a more balanced assessment of the various aspects of individuals' relationships with mobile phones...

Researchers recently have begun using Mechanical Turk (MTurk), an online crowdsourcing platform, to recruit addiction populations. However, whether the data obtained from substance users and gamblers on MTurk are reliable and valid is unknown. Herein, we assessed the internal and retest reliability of and concurrent and convergent validity of data obtained from addiction populations on MTurk. Current drinkers (N = 208), cannabis users (N = 200), and gamblers (N = 200) residing in the United States completed measures of alcohol, cannabis, and gambling severity, psychological constructs (e...

Monitoring cues, such as an image of a face or pair of eyes, have been found to increase prosocial behaviour in several studies. However, other studies have found little or no support for this effect. Here, we examined whether monitoring cues affect online donations to charity while manipulating the emotion displayed, the number of watchers and the cue type. We also include as statistical controls a range of likely covariates of prosocial behaviour. Using the crowdsourcing Internet marketplace, Amazon Mechanical Turk (MTurk), 1535 participants completed our survey and were given the opportunity to donate to charity while being shown an image prime...

BACKGROUND: Hoarding disorder (HD) is a common and debilitating disorder characterized by an accumulation of and failure to discard one's possessions. The identification and examination of underlying factors that may contribute to hoarding symptoms are needed to elucidate the nature of the disorder and refine existing treatments. Two transdiagnostic vulnerability factors that have been associated with hoarding symptoms are distress intolerance (DI) and intolerance of uncertainty (IU)...

BACKGROUND: Genomic research has innumerable benefits. However, if people are unwilling to participate in genomic research, application of knowledge will be limited. This study examined the likelihood of respondents from a high- and a low- to middle-income country to participate in genetic research. METHODS: Cross-sectional data were collected using Amazon's Mechanical Turk workforce to ascertain attitudes toward participation in genetic research. Registered country of residence was either the US (n = 505) or India (n = 505)...

BACKGROUND: One presentation of Avoidant/Restrictive Food Intake Disorder (ARFID) is characterized by picky eating, i.e., selective eating based on the sensory properties of food. The present study has two aims. The first is to describe distress and impairment in individuals with ARFID secondary to picky eating. The second is to determine whether eating behaviors hypothesized to be specific to picky eating can differentiate picky eaters with and without ARFID from typical eaters (e.g...

The present paper describes the general knowledge of smoking and nicotine among a sample of current smokers living with HIV (n=271) who were recruited via Amazon Mechanical Turk. Descriptive statistics were used to report sociodemographic and smoking characteristics, as well as knowledge about smoking and nicotine. The sample was comprised of relatively light smokers, both in terms of cigarettes per day (M=8.1, SD=9.7) and dependence (67.5% had low dependence according to the Heaviness of Smoking Index). The majority of participants correctly identified smoking as being a potential cause of various smoking-related conditions and correctly identified constituents in cigarette smoke...

OBJECTIVE: Young adults, in general, are not aware of their risk of knee osteoarthritis (OA). Understanding risk and risk factors is critical to knee OA prevention. We tested the efficacy of a personalized risk calculator on accuracy of knee OA risk perception and willingness to change behaviors associated with knee OA risk factors. METHODS: We conducted a randomized controlled trial of 375 subjects recruited using Amazon Mechanical Turk. Subjects were randomized to either a) use a personalized risk calculator based on demographic and risk factor information (intervention) or b) view general OA risk information (control)...
