Table 2 Parameter estimates for the logistic regression models for occurrence of flight responses and interruption of foraging behaviour in animals that startled in experiment 1

From: Repeated elicitation of the acoustic startle reflex leads to sensitisation in subsequent avoidance behaviour and induces fear conditioning

  Flight responses
  Chi-square B (log. reg.coeff.) Standard Error p-value Odds ratio (eB)
Startle pulse 23.05 0.424 0.088 < 0.001 1.53 (playback bout)
      2.34 (playback session)
Pre-sound only 15.91 0.934 0.234 < 0.001 2.55 (bout and session)
Intercept 10.97 -1.782 0.538 0.001 0.168
  Fish retrieval prevented
Startle pulse 12.69 0.393 0.110 < 0.001 1.49 (playback bout)

Pre-sound only 7.62 1.139 0.413 0.006 3.13 (bout and session)
Intercept 1.23 -0.634 0.571 0.267 0.530
  1. Parameter estimates for the logistic regression models fitted to the data from experiment 1 (flight responses and fish retrieval in animals that startled). The odds ratio gives the increase in the odds of the respective event occurring with each additional playback bout and playback session.
