Decision-making and dynamics of eye movements in volleyball experts
Published in Scientific Reports
Key decision-makers among experts in a given field can sometimes be identified based on their role and responsibilities. The aim of the study is to compare perceptual-cognitive skills of experts with decisional responsibilities (setters in volleyball) with that of other volleyball experts. Eighty-two participants (26 setters, 36 other players and 2...
Perception of saccadic reaction time
Published in Scientific Reports
That saccadic reaction times (SRTs) may depend on reinforcement contingencies has been repeatedly demonstrated. It follows that one must be able to discriminate one’s latencies to adequately assign credit to one’s actions, which is to connect behaviour to its consequence. To quantify the ability to perceive one’s SRT, we used an adaptive procedure ...
Large-scale dynamics of perceptual decision information across human cortex
Published in Nature Communications
Even decisions based on simple sensory stimuli result from an interplay between many brain regions. Here, the authors track the dynamics of information about sensory input and behavioral choice across the human cerebral cortex, uncovering feedback of decision signals to early sensory cortex.
GABAergic motor neurons bias locomotor decision-making in C. elegans
Published in Nature Communications
Motor neurons are generally considered to be passive receivers of commands from other neurons. However, this study shows that motor neurons may shape locomotor behaviour by regulating premotor neurons, and that premotor neurons serve to integrate information from sensory neurons and motor neurons.
Functional parcellation of the default mode network: a large-scale meta-analysis
Published in Scientific Reports
The default mode network (DMN) consists of several regions that selectively interact to support distinct domains of cognition. Of the various sites that partake in DMN function, the posterior cingulate cortex (PCC), temporal parietal junction (TPJ), and medial prefrontal cortex (MPFC) are frequently identified as key contributors. Yet, it remains u...
Contribution of self- and other-regarding motives to (dis)honesty
Published in Scientific Reports
Why would people tell the truth when there is an obvious gain in lying and no risk of being caught? Previous work suggests the involvement of two motives, self-interest and regard for others. However, it remains unknown if these motives are related or distinctly contribute to (dis)honesty, and what are the neural instantiations of these motives. Us...
Visual-reward driven changes of movement during action execution
Published in Scientific Reports
Motor decision-making is often described as a sequential process, beginning with the assessment of available options and leading to the execution of a selected movement. While this view is likely to be accurate for decisions requiring significant deliberation, it would seem unfit for choices between movements in dynamic environments. In this study,...
Transferring structural knowledge across cognitive maps in humans and models
Published in Nature Communications
Humans are able to exploit patterns or schemas when performing new tasks, but the mechanism for this ability is still unknown. Using graph-learning tasks, we show that humans are able to transfer abstract structural knowledge and suggest a computational mechanism by which such transfer can occur.
Unconscious reinforcement learning of hidden brain states supported by confidence
Published in Nature Communications
Humans can unconsciously learn to gamble on rewarding options, but can they do so when it comes to their own mental states? Here, the authors show that participants can learn to use unconscious representations in their own brains to earn rewards, and that metacognition correlates with their learning processes.
