In subliminal stimuli research, the threshold is the level at which the participant is not aware of the stimulus being presented. [9] Researchers determine a threshold for the stimulus that is used as the subliminal stimulus. That stimulus is then presented during the study at some point and measures are taken to determine the effects of the ...
Such points delineate boundaries of perception; that is, a limen defines a sensory threshold beyond which a particular stimulus becomes perceivable, and below which it remains unperceivable. [1] Liminal, as an adjective, means situated at a sensory threshold, hence barely perceptible. Subliminal means below perception.
Subliminal may refer to: Subliminal stimuli , sensory stimuli below an individual's threshold for conscious perception Subliminal channel , in cryptography, a covert channel that can be used over an insecure channel
For many sensory modalities, over a wide range of stimulus magnitudes sufficiently far from the upper and lower limits of perception, the 'JND' is a fixed proportion of the reference sensory level, and so the ratio of the JND/reference is roughly constant (that is the JND is a constant proportion/percentage of the reference level).
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
Dehaene reviews unconscious brain processing of various forms: subliminal perception, Édouard Claparède's pinprick experiment, blindsight, hemispatial neglect, subliminal priming, unconscious binding (including across sensory modalities, as in the McGurk effect), etc. Dehaene discusses a debate over whether meaning can be processed unconsciously and concludes based on his own research that ...
Priming is a concept in psychology to describe how exposure to one stimulus may influence a response to a subsequent stimulus, without conscious guidance or intention. [1] [2] [3] The priming effect is the positive or negative effect of a rapidly presented stimulus (priming stimulus) on the processing of a second stimulus (target stimulus) that appears shortly after.
The "pure-capture" model focuses on stimulus salience. [5] If certain properties of a stimulus stand out from its background, the stimulus has a higher chance of being selected for attentive processing. [4] This is sometimes referred to as "bottom-up" processing, as it is the properties of the stimuli which affect selection.
