Our ability to perform tasks is constrained by our limited mental resources, which mandates that people should minimize use of cognitively "effortful" processing when possible. Recent theories posit that decisions to expend effort are governed by a cost-benefit tradeoff, whereby the potential benefits of effort can offset its perceived costs. I will present a series of recent, computationally-informed experiments combining computational modeling and behavioral experimentation to gain critical insights into understanding when and why we allocate—or withhold—cognitive effort, both from an individual differences perspective, and at the level of the task by examining the effect of changes in costs and benefits. Further illuminating these questions, we leverage psychophysiological measures such as pupillometry, and facial EMG to examine cost-benefit effort valuation as well as concurrent effort expenditure. Highlighting the usefulness of these measures, I will also describe new work examining how physiological markers of online effort expenditure can be used to understand cognitive demand avoidance in the context of risky decision-making, shedding new light on ‘how we decide how to decide.’ Taken together, these lines of work illustrate how our decisions to deploy effortful cognitive processing can be understood in a decision-theoretic framework.

For these monthly get-togethers everyone is welcome to join, whether you want to listen or actively contribute to the discussion. The aim is to have some space to reflect and learn from each other.

Time:15.00-16.00
Place: 0B23
Speakers: Prof. Christine Bastin & Anaïs Servais  - University of Liège

In this meeting Prof. Christine Bastin will first present an overview of the ongoing work at GIGA CRC Human Imaging & Psychology and Cognitive Neuroscience. In the second part, Anaïs Servais will present recent experimental findings from their lab.

Time: 16.00-18.00 h

Abstract: A key assumption of psychology research is that participants provide sincere responses when completing questionnaires and other tasks. However, this assumption is rarely tested. In this talk I present research showing that insincere responding can be more common—and more pernicious—than you might think.
