Testing possible mechanisms of deficient supra-second time estimation in adults with attention-deficit/hyperactivity disorder.

30 Aug 2009 Numerous studies indicate deficient time estimation in individuals with attention-deficit/hyperactivity disorder (ADHD). Several hypotheses have been raised to explain this deficit including delay aversion, vulnerability to nontemporal distractions, ... Read more...

Frontal attentional responses to food size are abnormal in obese subjects: an electroencephalographic study.

16 Jul 2009 OBJECTIVE: Are obese subjects characterized by a reduction of attentional cortical responses to the enlargement of food or body images? METHODS: Electroencephalographic data were recorded in 19 obese and 15 normal-weight adults during an "oddball" ... Read more...

A large-scale retrospective study of closing-in behavior in Alzheimer's disease.

30 Jun 2009 The frequency and characteristics of closing-in behavior (CIB) were examined in 797 patients with Alzheimer's disease (AD), 132 of whom were followed up longitudinally. The frequency of CIB increased with the complexity of the graphic copying task ... Read more...

Technical information about 'Perceptual Disorders'

Definition: Cognitive disorders characterized by an impaired ability to perceive the nature of objects or concepts through use of the sense organs. These include spatial neglect syndromes, where an individual does not attend to visual, auditory, or sensory stimuli presented from one side of the body.
