Attunement of maternal and child adrenocortical response to child challenge.

Although a great deal is known about physiological responding to stress in nonhuman animals, and also about individual differences in behavioral attunement in humans, physiological attunement between human mothers and their children has never been ...

Functional MRI for neurofeedback: feasibility study on a hand motor task.

We present an fMRI-based method that enables subjects to monitor and actively modulate their own brain activity as a form of biofeedback. On a 1.5 T clinical MR scanner, functional areas during a simple hand motor task were delineated by detecting signal ...

Soccer players and closed-skill athletes execution of a complex motor skill.

The main purpose of this study was to investigate possible differences in speed and accuracy of motor execution among female soccer players in an Expert Soccer group, a Novice Soccer group, and a Closed-skill Athlete group. There were two main findings. ...

Body mass index and physical function in older women.

OBJECTIVE: We modified existing standardized measurement tools in the Physical Performance Test and tasks from the Frailty and Injuries: Cooperative Studies of Intervention Technique Study to evaluate physical function in older women. Our objectives were ...

Repetitive transcranial magnetic stimulation of the supplementary motor area (SMA) degrades bimanual movement control in humans.

Moving the upper limbs at a common tempo according to an in-phase or anti-phase mode represents elementary coordination dynamics. Previously, the role of the supplementary motor area (SMA) has been emphasized for successful production of these patterns. ...

Understanding muscle coordination of the human leg with dynamical simulations.

Muscles coordinate multijoint motion by generating forces that cause reaction forces throughout the body. Thus, a muscle can redistribute existing segmental energy by accelerating some segments and decelerating others. In the process, a muscle may also ...

Stigma and its management: a pilot study of parental perceptions of the experiences of children with developmental coordination disorder.

The findings of a small qualitative interview study with 8 parents of 6 children with developmental coordination disorder are reported. The parents discussed the social consequences of their childrens motor difficulties. The new International ...

Partial advance information, number of alternatives, and motor processes: an electromyographic study.

We present evidence that advance information reducing the number of stimulus-response alternatives in a choice reaction time (RT) task can shorten the very latest motoric stages of RT. Effects of such advance information on late stages of RT have been ...

Effects of alcohol and cigarette use on cognition in middle-aged adults.

In this retrospective cohort study we examined the independent and interactive effects of drinking and smoking on cognition in a sample of 3361 males, ages 31 to 49, with varying lifetime histories of alcohol and cigarette use. Dependent variables were ...

Cognitive processes and motor skills differ in sensitivity to alcohol impairment.

OBJECTIVE: Research reviews have suggested that cognitive and motor skills are not equally sensitive to a moderate dose of alcohol; they disagree, however, on which type of task is more sensitive to impairment. This issue is addressed in two experiments ...
