Subliminal stimuli can elicit significant emotional changes, but these changes are not valuable for a therapeutic effect. [23] This has been proposed to be caused by a little influence of subliminal stimuli on the cognitive circuits that – together with survival ones – contribute to the conscious experience of fear.
Some studies show that subliminal stimuli can affect attitude. In a 1992 study Krosnick, Betz, Jussim and Lynn conducted a study where participants were shown a series of slides in which different people were going through normal every day activities (i.e. going to the car, sitting in a restaurant).
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 ...
In perceptual psychology, a stimulus is an energy change (e.g., light or sound) which is registered by the senses (e.g., vision, hearing, taste, etc.) and constitutes the basis for perception. [2] In behavioral psychology (i.e., classical and operant conditioning), a stimulus constitutes the basis for behavior. [2]

[1] Although these processes exist beneath the surface of conscious awareness, they are thought to exert an effect on conscious thought processes and behavior. [2]
Modern medical and psychological investigations into consciousness are based on psychological experiments (including, for example, the investigation of priming effects using subliminal stimuli), [81] and on case studies of alterations in consciousness produced by trauma, illness, or drugs. Broadly viewed, scientific approaches are based on two ...

Method of constant stimuli: Stimuli of varying intensities are presented in random order to a subject. Intensities involve stimuli which are surely subthreshold and stimuli which are surely supra-threshold. For the creation of the series, the approximate threshold judged by a simpler method (i.e.: by the method of limits).
