Which theoretical view would suggest that viewing a horror film late at night might lower your absolute auditory threshold as you subsequently attempt to fall asleep?
Show answer Hide answer
Answer: C. Signal detection theory
Explanation
Signal detection theory incorporates internal psychological states and expectations into perceptual threshold judgments. Fear from watching a horror film increases vigilance and alertness toward potential environmental noises. This heightened psychological arousal effectively lowers the detection threshold for faint auditory stimuli. Signal detection theory evaluates how observers distinguish between meaningful sensory signals and background noise. The framework accounts for both sensory sensitivity and individual response bias under conditions of uncertainty. Physiological arousal significantly alters an observer's criterion for reporting the presence of a weak stimulus.
This theory applies broadly to medical diagnostic testing, quality control inspection, and eyewitness testimony reliability. Security personnel utilize these principles to maintain high vigilance when screening for rare dangerous objects. Understanding detection limits helps explain why frightened individuals perceive harmless nighttime creaks as threats. Prime theory relates to cognitive priming effects rather than perceptual sensitivity and decision criteria. Opponent process theory describes emotional adaptation and color vision processing rather than auditory thresholds. Frequency theory explains how the cochlea encodes pitch by matching the firing rate of auditory neurons.
