Figure 1From: Repeated elicitation of the acoustic startle reflex leads to sensitisation in subsequent avoidance behaviour and induces fear conditioningBehavioural responses of seals (n = 7) to the three treatments in experiment 1. Responses of seals that startled (left column) and those that did not startle (right column) to the treatments (a) startle pulse (with pre-sound), (b) pre-sound only, (c) no sound control. The response variables haulout time and time spent close to feeder are shown as mean +/- standard error. Note that the "pre-sound only" treatment was only used from session number 4 onwards.Back to article page
