Schematic representation of the gap-startle paradigm. For both no-gap (A) and gap (B) trials, a continuous background carrier noise (6, 12, 16, 20 or 24 kHz narrowband noise; 60 dB SPL) was presented for the duration of the inter-trial interval. The startle response was elicited with either a 20 ms broadband noise at 115 dB SPL or a 20 ms airpuff to the back of the neck (112 dB SPL). For gap trials (B) a 75 ms silent gap was inserted into the background carrier noise 100 ms prior to the startle stimulus.
