Practice question · Put in order
Order what happens when a stick-shaped shadow triggers both of LeDoux's pathways.
- The amygdala's alarm is dialed back once the 'all clear' arrives
- The high road's cortical processing identifies it as a harmless stick
- You jump back defensively before consciously recognizing it
- The low road rushes a crude signal straight to the amygdala
- Sensory information about the shadow reaches the thalamus
Hints
- The fast crude reaction happens BEFORE the slow accurate identification.
- The cortex's correction arrives after the defensive jump, not before.
Show the answer
- Sensory information about the shadow reaches the thalamus
- The low road rushes a crude signal straight to the amygdala
- You jump back defensively before consciously recognizing it
- The high road's cortical processing identifies it as a harmless stick
- The amygdala's alarm is dialed back once the 'all clear' arrives
Why
The thalamus feeds both roads; the low road fires the defensive jump before recognition, then the slower high road identifies the harmless stick and calls off the alarm. Speed first, accuracy just after - the point of the two-pathway design.
