Longitudinal motor development of "apparently normal" high-risk infants at 18 months, 3 and 5 years.

BACKGROUND: Motor development appears to be more affected by premature birth than other developmental domains, however few studies have specifically investigated the development of gross and fine motor skills in this population. AIM: To examine ...

Chronometric comparisons of imagery to action: visualizing versus physically performing springboard dives.

Motor imagery research emphasizes similarities between the mental imagery of an action and its physical execution. In this study, temporal differences between motor imagery and its physical performance as a function of performer expertise, skill ...

Habit and skill learning in schizophrenia: evidence of normal striatal processing with abnormal cortical input.

Different forms of nondeclarative learning involve regionally specific striatal circuits. The motor circuit (involving the putamen) has been associated with motor-skill learning and the dorsolateral prefrontal cortex (DLPFC) circuit (involving the ...

MEG study of long-term cortical reorganization of sensorimotor areas with respect to using chopsticks.

The movements required to use chopsticks are overlearned and routine in Asians. Most non-Asians, on the other hand, typically have difficulty performing this unfamiliar manual activity, and have to focus their attention on the movements required to use ...

Motor output is more variable during eccentric compared with concentric contractions.

PURPOSE: This study examined the ability of 10 young (25.3 +/- 2.8 yr) healthy individuals to control knee-extension force during several discrete concentric and eccentric contractions. METHODS: Subjects performed maximal and submaximal tasks on a ...

Imagery practice and the development of surgical skills.

BACKGROUND: The purpose of this review is to explore the potential role of imagery practice during the acquisition of surgical skills, imagery practice being the mental rehearsal of a skill. METHODS: The core of this review is derived from a literature ...

Homocysteine levels and decline in physical function: MacArthur Studies of Successful Aging.

PURPOSE: To test whether elevated homocysteine levels are associated with an increased risk of decline in physical function in older persons. METHODS: We performed a prospective cohort study of 499 highly functioning men and women aged 70 to 79 years who ...

Backed tools in Middle Pleistocene central Africa and their evolutionary significance.

The fashioning of stone inserts for composite tools by blunting flakes and blades is a technique usually associated with Late Pleistocene modern humans. Recent reports from two sites in south central Africa (Twin Rivers and Kalambo Falls) suggest that ...

Are traditional cognitive tests useful in predicting clinical success?

The purpose of this research was to determine the predictive value of the Dental Admission Test (DAT) for clinical success using Ackermans theory of ability determinants of skilled performance. The Ackerman theory is a valid, reliable schema in the ...

Physiological effects of an 8-week mechanically aided resistance facial exercise program.

This paper describes a study that for the first time addresses the physiological effects of an 8-week mechanically aided facial exercise program, using the Facial-Flex device (Facial Concepts, Inc., Blue Bell, PA) with four healthy individuals with no ...
