Motor development and cognitive development may be fundamentally interrelated. Contrary to popular notions that motor development begins and ends early, whereas cognitive development begins and ends later, both motor and cognitive development display equally protracted developmental timetables. When cognitive development is perturbed, as in a neurodevelopmental disorder, motor development is of...

head trauma associated with multiple destructive cognitive symptoms. cognitive destruction leads to impairment in cognitive tasks and cognitive failure. cognitive failures include problems with memory, attention, and operation. this study aimed to comparing cognitive failures in mild traumatic brain injury (tbi) patients and normal people in kashan. the study was performed on 40 tbi patients re...

Motor imagery (MI), sharing similar neural representations to motor execution, is regarded as a window to investigate the cognitive motor processes. However, in comparison to simple limb motor imagery, significantly less work has been reported on brain oscillatory patterns induced by compound limb motor imagery which involves several parts of limbs. This study aims to investigate differences of...

OBJECTIVES The authors report the results of detailed investigations into the motor function of a patient who, after a heavy drinking binge and subsequent unconsciousness, respiratory acidosis, and initial recovery, developed parkinsonism characterised by hypophonic speech and palilalia, "fast micrographia", impaired postural reflexes, and brady/akinesia in proximal (but not distal) alternating...

The coupling of perception and action in humans and other species is one of the major questions in cognitive science and neuroscience. The empirical domain of perceptionlaction includes reaching and grasping, skilled use of tools, visual control of locomotion (e.g., driving and flying), dance, and individual and team sports. Understanding of perceptionlaction in the human requires research on p...

Gender differences in the visuo-spatial and mathematical cognitive domain seem to rely on the preferences for different cognitive strategies. Such differences may involve or reflect different neural circuits. In this study three number related tasks and a mental rotation fMRI-paradigm were used to examine whether different brain activation and performance patterns could be observed between gend...

The authors describe ACT-R/perceptual-motor (ACT-R/PM), an integrated theory of cognition, perception, and action that consists of the ACT-R production system and a set of perceptual-motor modules. Each module (including cognition) is essentially serial, but modules run in parallel with one another. ACT-R/PM can model simple dual tasks such as the psychological refractory period (PRP), includin...

Changes in psychomotor slowing were studied in 21 inpatients with a Major Depressive Episode. Fine motor retardation was measured and analysed using computer-aided drawing and figure-copying tasks at T0 (the start of 6 weeks treatment with fluoxetine 20 mg/day) and 5 weeks later (T1). The differences in reaction time between the patients and a group of healthy, matched controls at T0 had disapp...
