Table 1. Predictions of behavioural outcomes for potential strategies used by prey to predict the change in risk through time based on prior information.

Treatment	Potential strategies:
	use recent	average	extrapolate
consistent high risk: high-high-high	high	high	high
no risk: nil-nil-nil	nil	nil	nil
steady increase: low-medium-high	high	medium	>high
abrupt increase: low-sham-high	high	medium	>high

Potential strategies include using only the most recent information, averaging all information through time, and extrapolating from prior risk patterns. High/medium/>high refers to the intensity of response displayed by the prey when exposed to the predator cues.
