Selective attention and uncertainty

Uncertainty, Neuromodulation, and Attention

Uncertainty in various forms plagues our interactions with the environment. In a Bayesian statistical framework, optimal inference and prediction, based on unreliable observations in changing contexts, require the representation and manipulation of different forms of uncertainty. We propose that the neuromodulators acetylcholine and norepinephrine play a major role in the brain's implementation...

Effectiveness of Music Therapy on Sustained Attention and Selective Attention in Children with Attention Deficit/ Hyperactivity Disorder

The aim of this study was to evaluate the effectiveness of music therapy on sustained attention and selective attention in children with attention deficit hyperactivity disorder. The research method was quasi-experimental with a pre-test-post-test design with a control group. The statistical population included all children with attention deficit-hyperactivity disorder who referred to psycholog...

Attention, Uncertainty, and Free-Energy

We suggested recently that attention can be understood as inferring the level of uncertainty or precision during hierarchical perception. In this paper, we try to substantiate this claim using neuronal simulations of directed spatial attention and biased competition. These simulations assume that neuronal activity encodes a probabilistic representation of the world that optimizes free-energy in...

Selective attention.

Sense, Reference and Selective Attention

he idea that there is a distinction between propositional and Ti magistic content is familiar and compelling, but it brings with it a problem. The problem is to explain the relation between the two types of content. This problem can seem so difficult that to escape it, you would abandon the propositional/imagistic distinction. But that is an extreme reaction; we can solve the problem. My propos...
