In psychophysics, sensory threshold is the weakest stimulus that an organism can sense.Unless otherwise indicated, it is usually defined as the weakest stimulus that can be detected half the time, for example, as indicated by a point on a probability curve. [1]
Marvin Zuckerman (March 21, 1928, in Chicago – November 8, 2018 [1]) was Professor Emeritus of Psychology at the University of Delaware. [2] Zuckerman is best known for his research into the psychobiological basis of human personality , [ 3 ] [ 4 ] sensory deprivation, [ 5 ] [ 6 ] mood state measurement, [ 7 ] [ 8 ] and sensation seeking .
Stevens' power law is an empirical relationship in psychophysics between an increased intensity or strength in a physical stimulus and the perceived magnitude increase in the sensation created by the stimulus.
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 ...
Ernst Heinrich Weber states that "the minimum increase of stimulus which will produce a perceptible increase of sensation is proportional to the pre-existent stimulus," while Gustav Fechner's law is an inference from Weber's law (with additional assumptions) which states that the intensity of our sensation increases as the logarithm of an ...
Energy psychology is also thought of as "acupuncture without needles" for treating psychological disorders. [9] Energy psychology has roots in applied kinesiology, traditional Chinese medicine, and clinical psychology. [7] For example, TFT involves utilizing imagery and/or thoughts, feelings, and acupuncture as a way of improving symptoms. [7]
The Sensation Seeking Scale is one of the most common psychological instruments for measuring sensation seeking. It was created in 1964 by Marvin Zuckerman , at the University of Delaware . [ 1 ] Zuckerman created the scale with the purpose of better understanding personality traits such as neuroticism , antisocial behavior , and psychopathy ...
Affective sensation is an occurrence of sensation accompanied with a strong compulsion to act on it. It refers, mostly in neuroscience, to the emotional sensibility in response to affective stimuli of a particular valence .
