Human Performance Laboratory


Human Performance Laboratory (SRL 1.104)



The focus of the Human Performance Lab is to investigate the cognitive and psychological factors that influence human performance and motor skill acquisition. Innovative research projects are conducted across a broad and diverse array of sports and motor control topics including examination of the influence of attention on sport performance, the role of perceptual feedback during motor learning, the prevention of choking under pressure, and the relearning of motor skills following a stroke. To explore these topics, the laboratory is equipped with a state-of-the-art Vicon motion tracking system, which enables real-time analysis of human movement and performance. Additionally, the laboratory is equipped with advanced eye tracking systems for gaze behavior analysis, biofeedback acquisition, and visual occlusion research.

Influence of Action Effects in the Control of Complex Actions  

Humans move in order to bring about desired effects in the environment. It is not surprising then that anticipation of these action effects are also thought to play an important role in the planning and execution of human action. In order to better understand this relationship, we are currently conducting research that is aimed at illuminating how these action-effect relationships can be used to facilitate performance within complex human actions.

Internal and External Focus Effects on Human Performance

In recent years, a considerable amount of research has shown that what one focuses on during skill execution can significantly influence learning and performance on a motor task. Specifically, an external focus (i.e., focus on the effects of the movement on the environment) has been shown to facilitate greater performance accuracy (e.g., Land & Tenenbaum, 2012), reduced attentional/working memory demands, reduced brain and muscle activity, and overall better outcome performance. In order to better understand how focus of attention aids motor learning and performance, this line of research examines the conditions and mechanisms underlying the superiority of an external focus.


UTSA undergraduate and Masters students are encouraged to volunteer with ongoing and upcoming projects. Additionally, Thesis projects are available for Masters students.
