q3 i? Massed 1000-Hz exposure in the first half of Exp 8b drives a long-lasting, frequency-specific detection decrement for subsequently encountered equiprobable frequencies, greatest at far and intermediate distances from 1000 Hz. → Luthra 2025

q3 · i? · causal · r2

Exp 8b (320 1000-Hz trials then 320 trials of 20 equiprobable tones excluding 1000 Hz) showed a Distance-from-1000-Hz × Exp interaction (p = 2.618e-4, η² = 0.007). Far and intermediate frequencies were detected less accurately than in Exp 8a (far: d = 0.330; intermediate: d = 0.346), with suppression persisting to the final 80 trials (d = 0.440).

"massed exposure to 1000 Hz in the first half of Exp 8b drives a dramatic, long-lasting, and frequency-specific detection decrement for the subsequently encountered 20 equiprobable frequencies, as compared to detection across equiprobable frequencies in Exp 8a"
