Cortical and subcortical functional specificity associated with response inhibition Ghent University
Is motor response inhibition supported by a specialised neuronal inhibitory control mechanism, or by a more general system of action updating? This pre-registered study employed a context-cueing paradigm requiring both inhibitory and non-inhibitory action updating in combination with functional magnetic resonance imaging to test the specificity of responses under different updating conditions, including the cancellation of actions. Cortical ...
A direct and conceptual replication of post-loss speeding when gambling Ghent University
To investigate the response to suboptimal outcomes, Verbuggen et al. (Verbruggen F, Chambers CD, Lawrence NS, McLaren IPL. 2017 Winning and losing: effects on impulsive action. J. Exp. Psychol.: Hum. Percept. Perform.43, 147. (doi:10.1037/xhp0000284)) conducted a study in which participants chose between a gamble and a non-gamble option. The non-gamble option was a guaranteed amount of points, whereas the gamble option was associated with a ...
Non‐problematic and problematic binge‐watchers do not differ on prepotent response inhibition : a preregistered pilot experimental study Ghent University
Binge‐watching (i.e., watching multiple episodes of a TV series back‐to‐back) has become standard viewing practice. Yet, this phenomenon has recently generated concerns regarding its potential negative outcomes on the long run. The presumed addictive nature of this behavior has also received increasing scientific interest, with preliminary findings reporting associations between binge‐watching, self‐control impairments, and heightened ...
Stroop-like effects of derived stimulus-stimulus relations Ghent University
The instructed task-switch evaluation effect : is the instruction to switch tasks sufficient to dislike task switch cues? Ghent University
It is often argued that people dislike situations in which there is conflict requiring cognitive control, possibly because it is effortful to resolve this conflict. In a recent study, Vermeylen, Braem, and Notebaert (2019) provided evidence for this idea in the context of task switching. They observed that participants evaluated cues signaling a task switch more negatively than cues signaling a task repetition in a task switching paradigm. The ...
An episodic model of task switching effects : erasing the homunculus from memory Ghent University
The Parallel Episodic Processing (PEP) model is a neural network for simulating human performance in speeded response time tasks. It learns with an exemplar-based memory store and it is capable of modelling findings from various subdomains of cognition. In this paper, we show how the PEP model can be designed to follow instructions (e.g., task rules and goals). The extended PEP model is then used to simulate a number of key findings from the ...
