The Perception & Action Podcast

Exploration of how psychological research can be applied to improving performance, accelerating skill acquisition and designing new technologies in sports and other high performance domains. Hosted by Rob Gray, professor of Human Systems Engineering at Arizona State University, the podcast will review basic concepts and discuss the latest research in these areas.

41 – Motion in Depth Blindness & Visual Channels Dec 06, 2016

Show notes

A look at visual channeling theory and its consequences for perception. Why are some people blind to approaching objects in certain areas of their visual field and what implications does it have for sport?

40B – Report from Sports Biometrics Conference Nov 29, 2016

Show notes

My report from the Sports Biometrics Conference held from Nov 13-15, 2016. Issues discussed include validity of analytics data, whether athletes are going to agree to be continuously monitored and the frequent disconnect between science and practice.

40A – Anxiety & Performance: Planning Actions, Motor Learning and Holistic Goals Nov 22, 2016

Show notes

News: A look at a few recent articles examining the effects of anxiety and pressure on performance and methods for counteracting these effects. Does pressure effect the planning or online control of movements? Could increasing anxiety in practice benefit motor learning? What are holistic goals and how can they reduce pressure effects?

Articles:

The interaction between practice and performance pressure on the planning and control of fast target directed movement

Perceptual-motor learning benefits from increased stress and anxiety

Anxiety and motor performance: More evidence for the effectiveness of holistic process goals as a solution to the process goal paradox

40 – P&A Court I: Monocular vs Binocular Vision Nov 15, 2016

Show notes

Why do we have two eyes? Is binocular vision necessary for successful performance of motor actions like those involved in sports and driving? Or is it just redundant information? What is it like to live with just one eye?

39B – Specificity vs Variability in Training/My Ultra Update Nov 08, 2016

Show notes

Which is better: specific or variable practice? How does it depend on what you are trying to achieve in terms of retention and transfer of skill? The ultramarathon as a complex system and my report on surviving my first one!

39A – Halloween Special II: Effects of Fear on Perception & Performance Oct 31, 2016

Show notes

Is fear in a performer a debilitating problem that must be overcome? Or can freezing from fear actually improve our ability to perceive and act?

Simulated self-motion alters perceived time to collision

Freezing promotes perception of coarse visual features

Seeing fearful body language rapidly freezes the observer's motor cortex

39 – Perceptual-Motor Development II: Ecological Approach Oct 25, 2016

Show notes

A look at perceptual-motor development from the ecological perspective. If it's not pre-programmed by our genetics, how does a child's pattern of movements emerge from the dynamical constraints of their environment? And how does movement shape perceptual discovery?

38A – Interview with Andrew Wilson, Leeds Beckett, Ecological Approach Oct 18, 2016

Show notes

A discussion Andrew Wilson from Leeds Beckett. We discuss ecological psychology ideas like motor abundance, functional equivalence and degeneracy, Andrew's recent study on task dynamics and information in throwing, his work on affordances and throwing prehistoric stones, and the current and future state of the ecological approach.

38 – Perceptual-Motor Development I: Traditional Approaches Oct 13, 2016

Show notes

A look at perceptual-motor development from an information processing, stage-based perspective. What is the relative importance of genetics and early experience? Are their critical periods in which perceptual and motor skills must develop? What is an efference copy?

37D - Sciencing My Way Through Ultrarunning: Intro Oct 11, 2016

Show notes

Thinking aloud about some sports science issues as I prepare for my first 50K ultra. What is the optimal focus of attention for a runner and how does it change as you switch from road to trail? How can one best acquire the skill of downhill running? Does it depend on where you look?
