National Science Foundation (DFG) awards grant to Prof. Dr. Ulf-Dietrich Reips

National Science Foundation (DFG) awards grant to Prof. Dr. Ulf-Dietrich Reips: A new three-year collaborative project on “Replicability of Fundamental Results on Spatial-Numerical Associations in Highly Powered Online Experiments (e-SNARC)” was awarded for a collaboration between Prof. Dr. Nuerck (University of Tübingen), Dr. Krzysztof Cipora (Loughborough University, UK) and iScience group.

Project summary: Spatial-Numerical Associations (SNAs) play a fundamental role for how humans represent numbers, and how they learn and use mathematics. Among SNAs, the Spatial-Numerical Association of Response Codes (SNARC, i.e., faster responses to small / large magnitude numbers with left / right hand respectively) effect is the hallmark, most thoroughly investigated effect. Nevertheless, despite almost three decades of research, many pivotal questions still remain unresolved. This may be partly due to the fact that several early SNARC results were obtained in small N (and probably underpowered) experiments. Because this limitation holds even for theoretically important and popular foundations of the SNARC effect, our understanding of SNAs considerably lacks in solidity of evidence and makes our common ground for further research shaky. For the presently granted project, we identify 3 fundamental questions about the SNAs and the SNARC effect, which we plan to address in highly powered large-scale online experiments: (1) automaticity – i.e., how much active semantic processing of the numerical stimuli is needed to evoke the spatial association, (2) task (in- )dependence – i.e., whether and how SNAs differ depending on the specific task we use to measure them, and (3) context (in-)dependence – i.e., whether spatial associations depend only on relative or also on absolute numerical magnitudes. For future empirical and theoretical developments it is essential to clarify these fundamental properties of the SNARC effect and provide high-quality empirical evidence, whether and under which circumstances these properties exist or not, and how large and reliable they are.


Two small grants awarded for iScience

Two small grants awarded for iScience: The International Office awarded two teaching grants to iScience group for seminars to be taught by international faculty jointly with Prof. Reips. Prof. Michael Birnbaum (California State University Fullerton) will co-teach “Joint course on Internet-based Data Collection and Analysis” and Dr. Aexander Merkin (Auckland
University of Technology, NZ) will co-teach “Multicultural competency and methods”.

Abstract
The invitation methods of web surveys have been studied from various perspectives, but less is still known about how demographic factors affect the selection of entry options in mailed web survey invitation letters. In a postal invitation letter, we provided the following three options to enter our web survey: using the URL address, emailing the researcher to get a link to the web survey; texting one’s email address to the researcher to get a link to the web survey. The results of the multinomial logistic regression model show that the odds of selecting the option “Response link by e-mail”  is 4.1 times higher for those with a primary education than for those with an upper secondary education. In addition, an increase of one year in the respondent’s age increased the odds of selecting the “Response link by e-mail” option by approximately 5 percent. To conclude, the older and less educated people are, the less cognitively burdening entry options they tend to select.
