Description Marcelo Malbec De Vidts is a PhD candidate in Experimental Psychopathology at the Department of Psychology, Education and Child Studies at Erasmus University Rotterdam. His research is about how different ways of responding to uncertainty affect individuals. These consequences could be present in cognitive as well as affective domains of human life. To do so, he uses EEG to analyse brain activity in different computer-based scenarios (decision-making; fear processing; error monitoring).

Description My research interests lie in the intersection of Economics, Political Science, and Psychology. I am currently doing research on how incentives influence survey responses, how voting affects political preferences, and how to design just-in-time adaptive nudges.

The ninth OSCR ReproducibiliTea journal club will take place on July 8th at 14:00. This is a special one, because it is a combined session between OSCR and Rotterdam R.I.O.T.S.. More information on this wonderful partnership can be found on this blog post. The discussant will be Dr. Tonya White from the Department of Child and Adolescent Psychiatry and the Department of Radiology & Nuclear Medicine at Erasmus MC.

Description I am a PhD candidate in Experimental Psychopathology at the Department of Psychology, Education and Child Studies at Erasmus University Rotterdam. My research focuses on factors that influence how people generalize their fear across different objects/people/situations that they encounter in everyday life. I compare several psychophysiological and brain measures and the goal is to understand what makes fear generalization turn from a helpful trait to a maladaptive symptom.

Description Ilse van de Groep is a PhD Candidate at the SYNC lab (Erasmus University Rotterdam) and the Child and Adolescent Psychiatry Department (Amsterdam UMC, location VUmc). In her PhD project, Ilse examines several mechanisms that underlie distinct developmental trajectories of social and antisocial behavior in emerging adulthood, with a specific focus on the neural correlates of self-concept, vicarious reward learning, social evaluation and aggression regulation.

Broadly defined, Open Science aims to make the products of scholarly investigation accessible to as many people as possible. In empirical sciences, one of these products is data analysis. How can you build your analysis pipeline in a way that can easily be inspected, so that results can be reproduced both by novices and experts? With R, of course! 😄 The OSCR is happy to announce an online workshop entitled A Tour Around the Tidyverse World.

Description Andrik Becht is a postdoctoral researcher in the SYNC lab and at the Youth & Family department, Utrecht University. His research is specifically aimed at understanding adolescents’ identity development from both a neurobiological and contextual perspective (for instance, examining the role of parents and peers). Andrik also investigates possible consequences of ongoing identity uncertainty in adolescence, to ultimately answer the question why some adolescents thrive whereas others don’t.

The eighth OSCR ReproducibiliTea journal club will take place on June 10th at 11:00. The discussants will be Dr. Ian Hussey and Prof. Sean Hughes, from the Department of Experimental-Clinical and Health Psychology at Ghent University (Belgium). Ian and Sean will guide us through one of their latest papers1: Hussey, I., & Hughes, S. (2020). Hidden Invalidity Among 15 Commonly Used Measures in Social and Personality Psychology. Advances in Methods and Practices in Psychological Science.

In the context of the ongoing debate about the replication crisis in psychology, methodologists have criticized the common practice of null-hypothesis testing using p-values. As a result, more and more researchers recently started using so-called Bayesian statistics to analyze their data. But what does this “new” approach to statistics really mean? What are the differences between Bayesian statistics and Frequentist statistics? What are the advantages (or disadvantages) of the estimation of the “subjective probability” of a model as compared to the usual practice to test a model based on the “objective probability” of the data under the null-hypothesis?

A huge proportion of participants in behavioral science studies are recruited from “open sampling” services, such as Amazon Mechanical Turk and Prolific. These services can accelerate and democratize the production of scientific knowledge. They also allow researches to collect larger samples compared to traditional samples in behavioral research (e.g., undergraduate students). However, open sampling also poses unique challenges to behavioral researchers. For example, participants have increasing research experience, which can affect experimental validity and replicability; researchers face a tradeoff between collecting larger samples and providing ethical payments to individuals who participate in research to earn a living wage.
