The threshold that has not been surpassed is the absolute threshold - this is the minimum amount of light required for a person to perceive it. If the light bulb is not emitting enough light to surpass the absolute threshold, it will not be detected. Choice A (Difference threshold) refers to the smallest detectable difference between two stimuli. Choice C (Stimulus threshold) is not a commonly used term in psychology. Choice D (Transduction) refers to the process by which sensory information is converted into neural signals.
