This can also represent an increase of accuracy. Currently, the three most common neuroscience techniques informing sport and exercise research are electroencephalography, transcranial magnetic stimulation and functional magnetic resonance imaging. Other professionals utilize exercise and sports to enhance peoples lives and well-being throughout the entire lifespan. Such progressions may indeed be found for certain motor skills, but there are also motor skills that remain dependent on visual feedback (as well as proprioceptive feedback) even after prolonged practice. Stored in the long term memory, retrieved when we need to perform the skill. Motor skill learning is defined as the process by which movements are executed more quickly and accurately with practice. These laws are of interest to sport and exercise psychologists because they specify relatively simple […] This mechanism is crucial for observational learning. The improvement of speed is captured by … The example of throwing a ball ...

TY - GEN. T1 - A sensory feedback system utilizing cutaneous electrical stimulation for stroke patients with sensory loss. AU - Kita, Kahori. AU - Takeda, Kotaro. AU - Osu, Rieko. AU - Sakata, Sachiko. AU - Otaka, Yohei. AU - Ushiba, Junichi. PY - 2011/11/2. Y1 - 2011/11/2. N2 - Sensory disturbance is very common following stroke and may exacerbate a patients functional impairment, even if the patient has good motor function. For instance, patients with sensory disturbances will often grip an object with excessive or underestimated pinch pressure, because they do not receive the appropriate sensory feedback and must rely only on visual feedback. In this study, we developed a sensory feedback system that used cutaneous electrical stimulation for patients with sensory loss. In the system, electrical stimulation is modulated by the strength of pinch pressure and the patients are able to identify their fingertip pinch pressure. To evaluate the efficacy of the system, a clinical case study was ...

The goal of this research project is to better quantify human reactions to short bursts of noise, to complement research at NASA Langley Research Center on evaluating human response inside buildings to low-level sonic booms. The project involved exposing participants over 30-minute sessions to a number of 250 ms broadband noise bursts of certain levels, presented in a controlled yet randomized fashion throughout the session, and gathering responses on human perception and performance on an arithmetic task dealing with short-term memory. While previous research has demonstrated effects of noise bursts of varying amplitudes on other types of tasks that study cognitive processing including attention and at louder levels on this arithmetic task (i.e. 100 dB peak), more information is needed to indicate at what level and to what degree such noise bursts may impact human performance and perception. Twenty-seven test subjects were tested over multiple 30-minute test sessions, with four different levels of the

The volca fm is a three-voice digital FM synthesizer that completely reproduces the sound engine of a classic FM synthesizer, and provides compatibility with it as well. The unique volca interface makes it easy to manipulate distinctive FM sounds even if youre not familiar with the complexities of FM synthesis. The 16-step sequencer thats one of volcas features provides new functions such as WARP ACTIVE STEP and PATTERN CHAIN that let you make even more powerful rhythm patterns.

The resulting measure is the FRII, an interviewer-administered questionnaire with 11 items on functional reading activities most relevant to GAAMD patients: 1) reading written print, 2) reading to pay bills or write a check, 3) reading in order to take medicine, 4) reading instructions, 5) reading labels, 6) reading to play games, 7) reading to make or receive a telephone call, 8) reading words or numbers on the screen while watching television, 9) reading when using a computer, 10) reading street signs, and 11) reading signs for directions. For each reading activity, sub-items are asked about dependence on visual aids, adaptive behaviors and assistance from others to perform the activity. Item scores reflect decreasing levels of functional reading independence. The FRII is included as an exploratory outcome in a Phase Ib/II study of the safety and evidence of activity of an investigational drug in GAAMD patients.. ...

All stimuli were generated using the MATLAB (The MathWorks, MA) programming environment with Psychtoolbox (Brainard, 1997; Pelli, 1997) routines. The test stimulus whose orientation was to be judged was a sinusoidal grating with a hard-edged circular window (3° diameter). It was embedded at the center of a larger disk filled with a sinusoidal grating (8° diameter, the surround). Both grayscale gratings had a spatial frequency of 2 c/° and a luminance contrast of 100%. The test grating was always vertical (=0° hereafter). To aid the visibility of the test grating, the relative spatial phase difference between the test grating and the surrounding grating was always fixed at 1/4 pi (45°) although the absolute spatial phase was chosen randomly for each trial. Orientations of the surround were varied from 3° to 19° with a 2° step, both clockwise and counterclockwise, resulting in 18 conditions. The comparison grating was identical to the test grating except that its orientation was ...
