A4.02
Two-point discrimination threshold and body-site differences
Cards in this group · 6
- A4.02.1Two-point discrimination threshold is smallest at the fingertip and largest on the trunk
- A4.02.2Multi-point tactile encoding is bounded above by this threshold
- A4.02.3Simultaneous versus successive application yields different two-point thresholds
- A4.02.4Dynamic scanning across a surface gives finer spatial resolution than static contact
- A4.02.5The fingertip threshold sets the physical lower bound for dense tactile codes such as braille
- A4.02.6Threshold differences across body sites jump discontinuously rather than forming a smooth gradient
