Hypothesis
Repeated elicitation of the acoustic startle reflex leads to sensitisation in subsequent avoidance behaviour and induces fear conditioning.
Conclusion
The study shows that the acoustic startle reflex significantly influences long-term avoidance behaviour in grey seals.
Supporting Evidence
- Repeated startling led to increased avoidance of the feeding area.
- Seals that startled showed significant changes in behaviour over playback sessions.
- The study demonstrated that the startle reflex can act as an unconditioned stimulus in fear conditioning.
Takeaway
When seals hear a loud noise, they get scared and start avoiding the area, even if there's food nearby.
Methodology
The study involved exposing grey seals to underwater noise pulses and measuring their responses over multiple playback sessions.
Limitations
The study was limited to a small sample size of grey seals and may not generalize to other species.
Participant Demographics
The participants included three adult females, three juvenile females, and one juvenile male grey seal.
