Negative interpretation biases are thought to be core symptoms of mood and anxiety disorders. However, prior work using cognitive tasks measure such is largely restricted case-control group studies, which cannot used for inference about individuals without considerable additional validation. Moreover, very few measures fully translational (i.e., can across animals humans in treatment-development pipelines). This investigation aimed produce the first negative that both sensitive individual...
Physiological regulation strategies can be effective in reducing anxiety. However, while these are often learned and practised under low-stress conditions, they more likely to required conditions of high stress. We created virtual reality (VR) biofeedback games both teach participants a breathing technique then practise that present two studies: the first provides proof concept, demonstrating apply during stress, with significant lowering respiration rate increase heart variability (HRV)...
Abstract Photoplethysmography (PPG) offers a widely-used, convenient and non-invasive approach to monitoring basic indices of cardiovascular function such as heart rate blood oxygenation. However, while the pulse waveform, generated by PPG comprises features that are shaped physiological psychological factors, it is frequently overlooked in analyses data. We suggest studies could be enriched exploiting possibilities afforded systematic analysis waveforms. To do this we initially require...
Fear and anxiety are largely seen as separate entities, a distinction that inspires shapes basic clinical research. Evidence for this has rich translational base comes from physiological, behavioural neurobiological studies. But there is high degree of inconsistency number fundamental limitations lead us to question the validity distinction. We consider relevant research examine underlying assumptions, concluding that, though been influential useful, future progress requires we recognise it...
<ns4:p>Photoplethysmography offers a widely used, convenient and non-invasive approach to monitoring basic indices of cardiovascular function, such as heart rate blood oxygenation. Systematic analysis the shape waveform generated by photoplethysmography might be useful extract estimates several physiological psychological factors influencing waveform. Here, we developed robust automated method for systematic across individuals different contexts. We describe psychophysiologically-relevant...
