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...

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...

Assessment of unilateral spatial neglect: scoring star cancellation performance from video recordings--method, reliability, benefits, and normative data.

29 Jun 2009 Unilateral spatial neglect, a debilitating condition affecting awareness of one side of space, is commonly assessed using cancellation tasks in which patients cross out targets distributed over a sheet. Standard scores emphasize the left-right ... Read more...
