Figure 3From: Repeated elicitation of the acoustic startle reflex leads to sensitisation in subsequent avoidance behaviour and induces fear conditioningHabituation and sensitisation process in response to the non-startling and startling sound pulses (experiment 3). Habituation and sensitisation of behavioural avoidance as measured by mean haulout time and time spent close to feeder for two seals tested consecutively with non-startling (long rise time) and startle-eliciting (short rise time) stimuli. Lines show separate linear regression through the data points for each individual. These seals were not used in any of the other experiments.Back to article page
