Dynamical systems theory
Describes the relationship that exists among the environmental, physical and behavioural properties of motor control

Recoil breath
Occurs when lung volume is low after going past REL. It is the involuntary abrupt increase in lung volume and is the sensation of breath rushing in without having to actively breathe.
Mucosal wave
Produced within the tissue of the TVF. Edge of the vocal fold deforms leaving a fluid wave visible. This wave ripples through the cover from the lower border to the side.
Attractor states
Used in dynamical systems theory to describe a condition of stability during motor tasks due to biomechanics and aerodynamics.
Habitual patterns of voice use but like the settings on a computer, can be changed.
Bernoulli principle
PAP in the lungs forces the TVF to open momentarily and the HVAP produces a lowered pressure which then sucks them back together.
Pitch raisers
Cricothyroid - pars oblique and pars recta
Plus the constricters
Pitch lowerers
Thyroarytenoid - lateral and medial
TVF openers
Posterior cricoarytenoid
TVF closers
- Lateral cricoarytenoid
- Thyroarytenoid
- Oblique interarytenoid
- Transverse interarytenoid
Magnitude estimation
- The perception of work and corresponds to measurements of that work.
- Kinaesthetic awareness.
Triggers FVF constriction
- Thoracic fixation
- End of phrases going past REL
- High intensity VQ
- Extremes of vocal range
- Emotionally challenging entrances
Effort in pitch production
- Pitch is prepared in musculature of larynx before sound is heard
- Location will be different in lower and higher parts of the range
- Effort numbers differ for each part of the range
- Sometimes effort to produce high or low pitches can cause FVF constriction.
