- •
We examined whether startle potentiation is sensitive to reversal instructions.
- •
Reversal instructions were provided after a differential fear conditioning phase.
- •
FPS was in line with the verbal instructions, but not actual CS–US pairings.
- •
SCR and expectancy ratings were affected by both CS–US pairings and instructions.
- •
The results argue for an expectancy learning account of FPS.
