BACKGROUND Noise is typically conceived of as being detrimental to cognitive performance. However, given the mechanism of stochastic resonance, a certain amount of noise can benefit performance. We investigate cognitive performance in noisy environments in relation to a neurocomputational model of attention deficit hyperactivity disorder (ADHD) and(More)
To study the neural bases of semantic composition in language processing without confounds from syntactic composition, recent magnetoencephalography (MEG) studies have investigated the processing of constructions that exhibit some type of syntax-semantics mismatch. The most studied case of such a mismatch is complement coercion; expressions such as the(More)
Perspectives I n this issue of PLoS Medicine, Lundy Braun and colleagues from the Race, Medicine, and Science Workshop discuss " the trouble with race " [1]. They argue that the heterogeneity of racial and ethnic categories (and a lack of consensus on how these categories should be defi ned and measured) make them poor markers for underlying differences in(More)

In this article, I show that the term is commonly used as a synonym for studies of clinical effectiveness and/or economic evaluations and argue that further factors relating to everyday working practice should be included(More)
This paper describes an effort to estimate variations in cognitive effort among cancer survivors experiencing treatment related cognitive decline. EEG-based cognitive state sensing algorithms were validated in the context of an experiment with 5 brain cancer and 5 breast cancer survivors. Workload was manipulated by varying text complexity and time(More)
