In the classic Stroop effect, naming the color of an incompatible color word (eg the word RED
printed in green ink; say, ‘green') is much slower and more error-prone than is naming the …

The present study investigated episodic memory functioning in: (1) obsessive compulsive
disorder (OCD) patients with primarily checking symptoms (ie checkers); (2) OCD patients …

Cognitive abnormalities are a feature of Parkinson's disease (PD). Unlike motor symptoms
that are clearly improved by dopaminergic therapy, the effect of dopamine replacement on …

The relation between attention at encoding and direct (ie, recognition) versus indirect (ie,
rapid reading) remembering was investigated. In Experiments 1 and 2, color of print indicated …

Mutations in the parkin gene result in an autosomal recessive juvenile-onset form of Parkinson's
disease. As an E3 ubiquitin-ligase, parkin promotes the attachment of ubiquitin onto …

The central aim of our study was to elucidate functions mediated by the ventral and dorsal
striatum, respectively, to better understand the cognitive effects of dopamine replacement in …

Awareness of self-generated movements arises from comparing motor plans, and the
accompanying (hypothetical) efference copy, with the visual and proprioceptive consequences of …

Parkinson’s disease (PD) is typically well recognized by its characteristic motor symptoms (eg,
bradykinesia, rigidity, and tremor). The cognitive symptoms of PD are increasingly being …

Objective Whether the dorsal striatum (DS) mediates cognitive control or cognitive effort per
se in decision-making is unclear given that these effects are highly correlated. As the …

Neuroimaging studies have revealed associations between intelligence and brain morphology.
However, researchers have focused primarily on the anatomical features of the cerebral …
