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 ...
Here, the critical parameter is the time interval (the SOA) between the onset of the subliminal stimulus and the onset of the masking stimulus. [1] In psycholinguistics the stimuli are typically a prime and a target, in which case the stimulus-onset asynchrony is measured from the beginning of the prime (S1) until the beginning of the target (S2).
Psychology textbooks present a similar view, stating that sublimation is "translating a distressing desire into an acceptable form." [ 2 ] It occurs when displacement involves "the transformation of sexual or aggressive energies into culturally acceptable, even admirable, behaviors," [ 3 ] and "serves a higher cultural or socially useful ...
Priming works most effectively when the two stimuli are in the same modality. For example, visual priming works best with visual cues and verbal priming works best with verbal cues. But priming also occurs between modalities, [7] or between semantically related words such as "doctor" and "nurse". [8] [9]
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 ...
Modern medical and psychological investigations into consciousness are based on psychological experiments (including, for example, the investigation of priming effects using subliminal stimuli), [92] and on case studies of alterations in consciousness produced by trauma, illness, or drugs. Broadly viewed, scientific approaches are based on two ...
As an example, the participant's task might be to indicate whether a visually presented number is smaller or larger than five, [33] such that the left-hand key is pressed for numbers "1" to "4" and the right-hand key is pressed for numbers "6" to "9". Based on the instruction, action triggers are set up that automatically elicit the response ...
Olaf Blanke's studies on out-of-body experiences explore an example where conscious experience changes while external stimuli stay the same. In Ch. 4, Dehaene notes that correlates of consciousness are actually insufficient, because many things can correlate with conscious perception, including even brain states prior to presentation of a stimulus.
