This study investigated acquisition of a mirror-reading skill via imagery training, without the actual performance of a mirror-reading task. In experiment I, healthy volunteers simulated writing on an imaginary, transparent screen placed at eye level, which could be read by an experimenter facing the subject. Performance of this irrelevant motor task required the subject to imagine the letters ...

this study aimed at investigating the effect of blocked, incremental systematic and random contextual interferences on acquisition, retention and transfer of volleyball skills based on changes in a generalized motor program. in fact, this study was conducted to answer this question that whether regular increment of contextual interference level is more effective on learning volleyball service s...

Knowledge Acquisition (KA) is an important phase of systems development for gathering expert domain knowledge that is incorporated into the requirements and design of a system. There are problems ensuring that accurate and useful knowledge is captured initially and transferred to later development efforts. We present a method, called tagging, for addressing these problems along with initial stu...

OBJECTIVE Psychophysical lift capacity tests are lifting tests in which the performance, expressed in Newtons, is divided by the perceived exertion, expressed on a Borg scale. The aim of this study was to analyse test-retest reliability of psychophysical lift capacity tests. SUBJECTS Patients with non-specific chronic low back pain (n=20) and healthy subjects (n=20). METHODS Psychophysical ...

Thirty young men were randomly assigned in equal numbers to one .of the following groups: placebo (lactose), secobarbital (100 mg), or d-amphetamine (10 mg). The drugs or placebo were administered in capsules in a double-blind procedure following practice at a tracking task and baseline determinations of tracking performance levels in both static (stationary) and dynamic (angular acceleration) ...

When an RTP receiver joins a multicast session, it may need to acquire and parse certain Reference Information before it can process any data sent in the multicast session. Depending on the join time, length of the Reference Information repetition (or appearance) interval, size of the Reference Information, and the application and transport properties, the time lag before an RTP receiver can us...

The purposes of this study were (a) to examine skill acquisition in field hockey of seven junior-high school students with PDD, who attended an inclusive class; and (b) to compare the degree of skill acquisition in field hockey of junior-high school students without disabilities who attend an inclusive class and those who attend a regular class. The motor performance of the students with and wi...
