AP PSYCHOLOGY

Detailed explanation-1: -It is also possible for us to get messages that are presented below the threshold for conscious awareness-these are called subliminal messages. A stimulus reaches a physiological threshold when it is strong enough to excite sensory receptors and send nerve impulses to the brain: this is an absolute threshold.

Detailed explanation-2: -Subliminal: below one’s absolute threshold for conscious awareness.

Detailed explanation-3: -An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time. The term is often used in neuroscience and experimental research and can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell.

Detailed explanation-4: -The “absolute threshold of sensation” refers to the minimum intensity of a stimulus that a person can detect half the time. This threshold is not fixed, but varies from person to person and can be influenced by psychological factors, such as expectations, motivation, and alertness.

Detailed explanation-5: -In subliminal stimuli research, the threshold is the level at which the participant is not aware of the stimulus being presented. Researchers determine a threshold for the stimulus that is used as the subliminal stimulus.
