From: Multiple factors contribute to flight behaviors during fear conditioning
Tone intensity was the primary factor to trigger flight behaviors in the fearful context. (A1) Averaged motions of each condition around the CS presentation by day are shown. In general, the groups conditioned with louder CSs exhibited more movement than those conditioned with softer CSs. (A2) Averaged total motions during the CS presentation of each trial are plotted. (B1) Averaged percentages of freezing during the CS presentation of each trial are plotted. (B2) Averaged jumps during the CS presentation of each trial are plotted. Subjects jumped more during CS presentations on days 3 and 4 in order from G1 to G4. (C1) Comparisons of motions, freezing, and jumps for factor ‘dB’. Averaged total motions, averaged percentages of freezing, and averaged total numbers of jumps by days are plotted. With louder CS, subjects exhibited more flight behavior. (C2) Comparisons of motions, freezing, and jumps for factor ‘mA’. Averaged total motions, averaged percentages of freezing, and averaged total numbers of jumps by days are plotted. The US intensity used for the conditioning did not have a strong effect on the expression of flight behaviors. *Indicates p < 0.05.
