outline
Outline
  • Basic idea of optimal mental functioning
  • Descriptive studies on EEG & motor performance
  • Interventional studies
characteristics of eeg psychophysiology
Characteristics of EEG psychophysiology
  • Noninvasiveness
  • Objective
  • Real time measurement of behavior
  • High temporal resolution
subjective experience of peak performance
Subjective Experience of Peak Performance
  • no fear of failure
  • no thinking of performance
  • total immersion in activity
  • narrow focus of attention
  • effortless performance
  • feeling of complete control
  • time/space disorientation
  • involuntary experience
psychomotor efficiency hypothesis
Psychomotor efficiency hypothesis
  • A reduction in the activity of nonessential cortical regions is characteristic of skilled motor performance (Hatfield & Hillmans, 2001).

classical study
Classical study
  • Hatfield, Landers, & Ray’s (1984) classical study on shooting:

1.Subject: 17 elite rifle shooters

2.Psychophysiological measures: 7.5

seconds of EEG alpha power prior to

trigger pull

3.Findings: ↑ alpha power at the left

hemisphere, right remains the same

interpretation
Interpretation

Alpha implies an idling state of the brain:

Higher alpha suggests inhibition of the left

brain verbal-analytical activity (e.g. Self

talk) and a shift to the right brain visual-

spatial activity.

signs of cortical adaptation
Signs of cortical adaptation
  • Expert-novice comparison:
  • Haufler et al. (2000) found less activation for expert than the novice shooters at all site. The difference was more pronounced in the left central-parietal-temporal region.

  • Expert-novice comparison:
  • Hung et al (2008) found lower dimension in EEG of expert shooter than novice
  • EEG dimension negatively correlate with shooting performance in expert shooters
supportive evidence 3
Supportive evidence 3
  • Skilled-Novice comparison on FmΘ(Lin et al, 2009)
  • Elite-preelite comparison on Coherence(Deeny et al, 2003)
  • Learning studies(Landers et al, 1994; Kerick et al, 2004)
intraindividual performance variation
Intraindividual performance variation
  • Loze et al. (2001) found higher alpha at left temporal and occipital region of the brain is associated with better shooting performance
  • Wu et al. (2007) found lower EEG coherence between frontal midline and other associative cortex in successful basketball free throw.

Can we help athletes control their brain activity?
  • Yes
  • Neurofeedback studies
  • Lander et al.(1991)-Archery
  • Lin(2004)-Archery

conclusion
Conclusion
  • The existing evidences suggest skilled motor performance has it’s psychophysiological signature
  • EEG psychophysiological approach provides ways to understand the neurophysiological mechanisms underlying the optimal mental states.
  • The approach also provides a way to help athletes control the mental states that leads to better performance
