Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is true?
A
Humans cannot sense stimuli below the absolute threshold
B
Humans cannot be affected by stimuli below the absolute threshold at all
C
Stimuli presented below the absolute threshold can have a subtle, brief effect on behavior
D
Stimuli presented below the absolute threshold exert a strong, powerful effect on behavior
Explanation: 

Detailed explanation-1: -Stimuli below the absolute threshold can still have at least some influence on us, even though we cannot consciously detect them. A variety of research programs have found that subliminal stimuli can influence our judgments and behaviour, at least in the short term (Dijksterhuis, 2010).

Detailed explanation-2: -The stimuli that are not enough to reach de absolute threshold and therefore are below to it are called subliminal stimuli.

Detailed explanation-3: -Which of the following is true? The absolute threshold for any stimulus is a constant. The absolute threshold for any stimulus varies somewhat. The absolute threshold is defined as the minimum amount of stimulation necessary for a stimulus to be detected 75% of the time.

Detailed explanation-4: -Absolute Threshold-the minimum level of a stimulus, below which there is no effect; the minimum amount below which something either does not exist or is so faint as to seem not to exist.

Detailed explanation-5: -Absolute threshold is the minimum stimulation needed to detect a particular stimulus (such as the sound of an approaching bike on the sidewalk behind us) 50 percent of the time. Subliminal stimulation happens when, without our awareness, our sensory system processes a stimulus (when it is below our absolute threshold).
