How do skilled performers achieve both speed and accuracy? Is it by reducing variability in movement parameters (i.e., repeatability)? Or is by allowing movement parameters to co-vary and compensate for each other (i.e., motor synergies)?   Articles: Control of Accuracy during Movements of High Speed: Implications from Baseball Pitching   More information: http://perceptionaction.com/ My Research...

What is a "smart" perceptual mechanism? How does it differ from the rote mechanisms used in information processing theory, where simple features are used for computation and processing? Are we missing opportunities to train the development of these smart perceptual mechanism in sports, forcing an athlete to see in terms of simple variables and categories, when we could be training them to pick up...

What is the role of the "self" in self organization? How does its pre-loaded conception lead to some misunderstanding about self-organization and misapplication of methods designed to promote it, like the CLA?

Conscious control seems to be far too slow to account for skilled performance in sports while using automatic habits seems not to be smart enough to allow for adaptation to the ever-changing constraints an athlete faces. How can we be both adaptable and fast? Does adaptability require mental representation? Articles: Neither mindful nor mindless, but minded: habits, ecological psychology, and skil...

How do changes in the perceptual information available alter movement variability? If we constrain vision with occluding glasses or constrain audition with headphones how do performers adapt their movements? How does this depend on skill level?   Article: The role of variability in the control of the basketball dribble under different perceptual setups   More information: http://perceptionaction.c...

How does the constraint of effort (for example, throwing at 80% of your max vs 100%) change the coordination of degrees of freedom in movement? Do movements become mostly invariant across individuals at max effort or is there still a role for variability?   Article: Effort‑dependent effects on uniform and diverse muscle activity features in skilled pitching   More information: http://perceptionact...

Does the representativeness of a practice task effect perceptual-motor calibration? For example, is the calibration of decision making and gaze behavior more effective when hitting off a pitcher vs a tee in baseball?   Article: To Tee, Or Not to Tee: Exploring the Relationship Between Representative Practice and Performance in Highly Skilled Baseball Hitters   More information: http://perceptionac...

A look at a new study comparing the effects of the CLA, differential learning, and prescriptive training on risk factors for ACL injury.

A look at some of the most interesting research articles from 2021 so far. How do constraints shape skill acquisition? How can we interpret some of the classic problems in perception from an ecological point of view? What have we learned about the search for optimal movement solutions?   Youtube Playlist Link: https://www.youtube.com/watch?v=-tpPmQVgEDw&list=PL7jcinNUb4UlH12FgDhLIT4mKfehB5Y_5    ...

Why do many individuals have a distinctive manner of performing a motor action (aka a perceptual-motor style)? How can we determine whether a particular style is functional? How do styles change with development, sports training and through rehabilitation? Articles: Perceptual‑motor styles A whole body characterization of individual strategies, gender differences, and common styles in overarm thro...

How can mapping a movement parameter into sound be used to aid motor learning? How can it be used to help stablilize movement patterns or alternatively encourage a learner to be creative and  look for new ones? Articles: Sonification Approaches in Sports in the past Decade: A Literature Review A Perspective on Implementing Movement Sonification to Influence Movement (and Eventually Cognitive) Crea...

Why do we sometimes start moving in completely the wrong direction before changing course when intercepting a moving object? Under what conditions do these "movement reversals" occur and what do they tells us about the use of predictive vs prospective control?     Articles: Movement reversals in ball catching Visual guidance of intercepting a moving target on foot Reversals in Movement Direction i...

A look at 1/f or pink noise in the motor system. How can it be used as a metric to understand the coordination of degrees of freedom in movement?
