While professional quarterbacks like Peyton Manning make passing a football look effortless, it takes a lifetime of disciplined practice for these elite athletes to reach such a high level of skill. The principal responsibility of the quarterback in American football is to throw a forward pass to his teammate. This skill, however, is not as trivial as it(More)
Feedback about error or reward is regarded essential for aiding learners to acquire a perceptual-motor skill. Yet, when a task has redundancy and the mapping between execution and performance outcome is unknown, simple error feedback does not suffice in guiding the learner toward the optimal solutions. The present study developed and tested a new means of(More)
The present study aimed to test the validity of upper extremity joint angle measurements with the Microsoft Kinect for shoulder rehabilitation. Results indicate that there are large discrepancies in measured shoulder angles from the Kinect compared to the gold standard (magnetic tracker) and the clinical standard (goniometer). Before the Kinect can be used(More)
Physical human–robot collaboration is becoming more common, both in industrial and service robotics. Cooperative execution of a task requires intuitive and efficient interaction between both actors. For humans, this means being able to predict and adapt to robot movements. Given that natural human movement exhibits several robust features, we(More)
Virtual reality-based physical rehabilitation, or virtual rehabilitation, provides several advantages over conventional therapy. These include the capacity to provide patient-specific treatment that adapts with functional improvements over practice, obtain quantitative measures of progress, deliver real-time performance feedback through varying modalities,(More)
Movement variability has been typically thought as detrimental, but it also plays a positive role for perception and action. One positive aspect is that it allows exploring different task solutions. Using a virtual throwing task [1], we examined how participants explore task solutions as they become more skilled. Naive subjects practiced 240 throws a day(More)
For the development and evaluation of cardiac magnetic resonance (MR) imaging sequences and methodologies, the availability of a periodically moving phantom to model respiratory and cardiac motion would be of substantial benefit. Given the specific physical boundary conditions in an MR environment, the choice of materials and power source of such phantoms(More)
Breathing-induced bulk motion of the myocardium during data acquisition may cause severe image artifacts in coronary magnetic resonance angiography (MRA). Current motion compensation strategies include breath-holding or free-breathing MR navigator gating and tracking techniques. Navigator-based techniques have been further refined by the applications of(More)
The majority of research on stereotype threat shows what is expected: threat debilitates performance. However, facilitation is also possible, although seldom reported. This study investigated how stereotype threat influences novice females when performing the sensorimotor task of bouncing a ball to a target. We tested the predictions of two prevailing(More)
Many studies using cognitive tasks have found that stereotype threat, or concern about confirming a negative stereotype about one's group, debilitates performance. The few studies that documented similar effects on sensorimotor performance have used only relatively coarse measures to quantify performance. This study tested the effect of stereotype threat on(More)
