Signal detection theory is concerned with how we discern a faint stimulus amidst background noise, and factors like expectations, experiences, and physiological state can influence this. Choices B, C, D, and E all relate to changes in sensory perception due to external or internal factors, which align with signal detection theory. Choice A, however, suggests a scenario where hunger status affects the noticing of a smell, which is more about sensory adaptation or attentional focus rather than signal detection theory's focus on the ability to identify a signal in the presence of noise.
