3.10 : 潜意识感知

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness.

Researchers study subliminal perception by presenting a stimulus to participants, such as a word or image, for around 50 milliseconds.

When an initial stimulus is quickly followed by another, such as a pattern of dots or lines, it masks further processing of the first stimulus. 

The first stimulus is considered subliminal if participants cannot identify it more accurately than by chance.

Studies have shown that when participants are subliminally exposed to words related to anger, they are more likely to rate other people as hostile.

Subliminal perception can also influence decisions like voting, product choices, and other life decisions, such as lifestyle changes and financial investments.

However, subliminal persuasion can still be ineffective because the brain can't fully understand and deeply process the meaning of subliminal stimuli, making these stimuli unlikely to produce significant or lasting changes in attitudes or decisions.
