ABSTRACT

Games, which can be defined as an externally structured, goal-directed type of play, are increasingly being used in high-stakes testing contexts to measure targeted constructs for use in the selection and promotion of employees. Despite this increasing popularity, little is known about how theory-driven game-based assessments (GBA), those designed to reflect a targeted construct, should be designed, or their potential for achieving their simultaneous goals of positive reactions and high-quality psychometric measurement. In the present research, we develop a theory of GBA design by integrating game design and development theory from human-computer interaction with psychometric theory. Next, we test measurement characteristics, prediction of performance, fairness, and reactions of a GBA designed according to this theory to measure latent general intelligence (g). Using an academic sample with GPA data (N = 633), we demonstrate convergence between latent GBA performance and g (ß = .97). Adding an organizational sample with supervisory ratings of job performance (N = 49), we show GBA prediction of both GPA (r = .16) and supervisory ratings (r = .29). We also show incremental prediction of GPA using unit-weighted composites of the g test battery beyond that of the g-GBA battery but not the reverse. We also show the presence of similar adverse impact for both the traditional test battery and GBA but the absence of differential prediction of criteria. Reactions were more positive across all measures for the g-GBA compared to the traditional test battery. Overall, results support GBA design theory as a promising foundation from which to build high-quality theory-driven GBAs. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

ABSTRACT

In the social and cognitive sciences, crowdsourcing provides up to half of all research participants. Despite this popularity, researchers typically do not conceptualize participants accurately, as gig-economy worker-participants. Applying theories of employee motivation and the psychological contract between employees and employers, we hypothesized that pay and pay raises would drive worker-participant satisfaction, performance, and retention in a longitudinal study. In an experiment hiring 359 Amazon Mechanical Turk Workers, we found that initial pay, relative increase of pay over time, and overall pay did not have substantial influence on subsequent performance. However, pay significantly predicted participants' perceived choice, justice perceptions, and attrition. Given this, we conclude that worker-participants are particularly vulnerable to exploitation, having relatively low power to negotiate pay. Results of this study suggest that researchers wishing to crowdsource research participants using MTurk might not face practical dangers such as decreased performance as a result of lower pay, but they must recognize an ethical obligation to treat Workers fairly.

ABSTRACT

The term big data encompasses a wide range of approaches of collecting and analyzing data in ways that were not possible before the era of modern personal computing. One approach to big data of great potential to psychologists is web scraping, which involves the automated collection of information from webpages. Although web scraping can create massive big datasets with tens of thousands of variables, it can also be used to create modestly sized, more manageable datasets with tens of variables but hundreds of thousands of cases, well within the skillset of most psychologists to analyze, in a matter of hours. In this article, we demystify web scraping methods as currently used to examine research questions of interest to psychologists. First, we introduce an approach called theory-driven web scraping in which the choice to use web-based big data must follow substantive theory. Second, we introduce data source theories, a term used to describe the assumptions a researcher must make about a prospective big data source in order to meaningfully scrape data from it. Critically, researchers must derive specific hypotheses to be tested based upon their data source theory, and if these hypotheses are not empirically supported, plans to use that data source should be changed or eliminated. Third, we provide a case study and sample code in Python demonstrating how web scraping can be conducted to collect big data along with links to a web tutorial designed for psychologists. Fourth, we describe a 4-step process to be followed in web scraping projects. Fifth and finally, we discuss legal, practical and ethical concerns faced when conducting web scraping projects.
