Which of the following is TRUE? - Stimuli presented below the absolute threshold exert a strong, powerful effect on behavior. - Humans cannot sense stimuli below the absolute threshold. - Humans cannot be affected by stimuli below the absolute threshold at all. - Stimuli presented below the absolute threshold can have a subtle, brief effect on behavior.

Answer: Stimuli presented below the absolute threshold can have a subtle, brief effect on behavior.

Explanation: The normal state of conciousness is vigil, that means that we are open to process the stimuli presented by the environment and ourselves. Some stimuli are subtle but have a brief impact on how we process to act, conditioning what we do next in order to act according to the context.

Sometimes, a subtle stimuli can also generate behavioral patterns if it is presented often.
