Data representation for joint kinematics simulation of the lower limb within an educational context.

Three-dimensional (3D) visualization is becoming increasingly frequent in both qualitative and quantitative biomechanical studies of anatomical structures involving multiple data sources (e.g. morphological data and kinematics data). For many years, this ...

Differential effects of alcohol and alcohol expectancy on risk-taking during simulated driving.

This study examined the separate and combined effects of alcohol (0.0 or 0.5 g/kg) and alcohol expectancies (none or 2-3 standard drinks) on risk-taking using a simulated-driving lane choice task. In this task, risk-taking was operationalized as choosing ...

Matching expression variant faces.

Several models have been proposed that attempt to explain how the brain identifies people by looking at their faces. However, to date, it is still not clear by which mechanism the brain successfully accomplishes the matching of two or more face images ...

Cognitive flexibility and adaptability to environmental changes in dynamic complex problem-solving tasks.

People who show good performance in dynamic complex problem-solving tasks can also make errors. Theories of human error fail to fully explain when and why good performers err. Some theories would predict that these errors are to some extent the ...

Optimised performance of the backward longswing on rings.

Many elite gymnasts perform the straight arm backward longswing on rings in competition. Since points are deducted if gymnasts possess motion on completion of the movement, the ability to successfully perform the longswing to a stationary final handstand ...

Non-linear viscoelastic models predict fingertip pulp force-displacement characteristics during voluntary tapping.

We evaluated whether lumped-parameter non-linear viscoelastic models of human fingertip tissue can describe fingertip force-displacement characteristics during a range of rapid, dynamic tapping tasks. Eight human subjects tapped with their index finger ...

Behavioral dynamics of steering, obstacle avoidance, and route selection.

The authors investigated the dynamics of steering and obstacle avoidance, with the aim of predicting routes through complex scenes. Participants walked in a virtual environment toward a goal (Experiment 1) and around an obstacle (Experiment 2) whose ...

Controlling steering and judging heading: retinal flow, visual direction, and extraretinal information.

The contribution of retinal flow (RF), extraretinal (ER), and egocentric visual direction (VD) information in locomotor control was explored. First, the recovery of heading from RF was examined when ER information was manipulated; results confirmed that ...

How does schema theory apply to real versus virtual memories?

Schemas are cognitive frameworks that guide memory, aide in the interpretation of events, and influence how we retrieve stored memories. The purpose of this study was to explore how schemas operate in a well-known environment and to examine whether or ...

Robonaut: a robot designed to work with humans in space.

The Robotics Technology Branch at the NASA Johnson Space Center is developing robotic systems to assist astronauts in space. One such system, Robonaut, is a humanoid robot with the dexterity approaching that of a suited astronaut. Robonaut currently has ...
