The relationship between anxious traits and learning about changes in stochasticity and volatility Open
Anxiety is known to alter learning in uncertain environments. Experimental paradigms and computational models addressing these differences have mainly assessed the impact of volatility, with more highly anxious individuals showing a reduce…

Investigating the use and impact of community Care (Education) and Treatment Reviews (C(E)TRs) in people with intellectual disability and autistic people: protocol for a cohort study using electronic health records Open
Introduction Care (Education) and Treatment Reviews (C(E)TRs) are intended to reduce unnecessary psychiatric hospital admission and length of stay for people with intellectual disability and autistic people. The use and impact of C(E)TRs h…

The “Tetris effect”: autistic and non-autistic people share an implicit drive for perceptual cohesion Open
Background When working on jigsaw puzzles, we mentally “combine” two pieces to form a composite image even before physically fitting them together. This happens when the separate pieces could logically create a cohesive picture and not whe…

Anxious individuals are more sensitive to changes in outcome variability and value differences in dynamic environments Open
Anxiety is known to alter learning in uncertain environments. Standard experimental paradigms and computational models addressing these differences have mainly assessed the impact of volatility, and anxious individuals have been shown to h…

The “Tetris effect”: Testing the implicit drive for perceptual cohesion in autism Open
The capacity of the brain to combine individual elements to form possible wholes serves as the basis of perceptual organisation. This drive for perceptual cohesion – the “Tetris effect” – can be seen in the famous game, where people automa…

Attention and reinforcement learning in Parkinson’s disease Open
Dopamine is known to be involved in several important cognitive processes, most notably in learning from rewards and in the ability to attend to task-relevant aspects of the environment. Both of these features of dopaminergic signalling ha…

Dopaminergic medication reduces striatal sensitivity to negative outcomes in Parkinson’s disease Open
McCoy et al. show that dopaminergic medication in Parkinson’s disease leads to changes in striatal signalling and in behaviour during learning, but that changes are specific to the processing of negative reinforcements. These within-patien…

Dynamic Functional Connectivity and Symptoms of Parkinson’s Disease: A Resting-State fMRI Study Open
Research has shown that dynamic functional connectivity (dFC) in Parkinson's disease (PD) is associated with better attention performance and with motor symptom severity. In the current study, we aimed to investigate dFC of both the defaul…

Dopaminergic medication reduces striatal sensitivity to negative outcomes in Parkinson’s disease Open
Reduced levels of dopamine in Parkinson’s disease (PD) contribute to changes in learning, resulting from the loss of midbrain dopamine neurons that transmit a teaching signal to the striatum. Dopamine medication used by PD patients has pre…

Overt and covert attention to location-based reward Open
Recent research on the impact of location-based reward on attentional orienting has indicated that reward factors play an influential role in spatial priority maps. The current study investigated whether and how reward associations based o…

Oculomotor properties associated with the enhanced feature representation of reward-signaling distractors Open
Recent studies have shown that reward learning affects attentional and oculomotor selection. Irrelevant distractor stimuli indicating the availability of reward can capture the eyes. It is assumed that this oculomotor capture effect is due…

Effects of reward on oculomotor control Open
The present study examines the extent to which distractors that signal the availability of monetary reward on a given trial affect eye movements. We used a novel eye movement task in which observers had to follow a target around the screen…
