Non-identical neural mechanisms for two types of mental transformation: event-related potentials during mental rotation and mental paper folding.
Reaction times, accuracy and 128-channel event-related potentials (ERPs) were measured from 14 normal, right-handed subjects while they performed two different parity-judgment tasks that require transformations of mental images: a relatively simple task requiring a single transformation (mental letter rotation), and a more complex task involving a coordinated sequence of transformations (mental...
متن کاملMental Rotation Mental Rotation
the typical characterization of individuals with mild mental retardation, by seldom being able to live independently. As evidenced by the example of Williams syndrome, summary test scores often do not represent well the level of ability within individual domains. Thus it is crucial to take into account etiology when planning either basic research or intervention. At the same time, it is importa...
متن کاملModeling Spatial Ability in Mental Rotation and Paper-Folding
Spatial ability tests like mental rotation and paper-folding provide strong predictions of an individual’s achievement in science and engineering. What cognitive skills are involved in them? We use a computational model to analyze these tasks, asking how much information must be processed to perform them. The models demonstrate that in some cases stimuli can be vastly simplified, resulting in c...
متن کاملAge-related differences of neural connectivity during mental rotation.
The purpose of the present study was to investigate age-related effects on functional brain networks during a mental rotation task. At behavioral level age-related cognitive deficits have been shown. Cognitive deficits in older adults are associated with structural decline, especially in frontal and parietal areas and in the corpus callosum. In consequence, functional networks are affected by o...
متن کاملEvent-related potentials during mental rotation tasks in patients with first-episode depression
BACKGROUND The ability to mentally rotate images is impaired in depressed patients but the electrophysiological abnormalities in the brain related to this impairment remain unclear. AIM To compare the event-related potentials (ERPs) of depressed patients and control subjects during the completion of a mental rotation (MR) task. METHODS Thirty-two inpatients and outpatients with first-episod...
