Home›Perception and Psychophysics Effects›All Perception and Psychophysics EffectsBrowse ByAll Perception and Psychophysics EffectsReference and ClassificationDevelopingGroups the phenomena of the psychology atlas whose central finding concerns how a stimulus is perceived, timed or sensed, rather than how a belief is judged, a memory is recalled or another person is read. Belongs here: Tachypsychia, a distortion of subjective time perception under exertion, drugs or a traumatic event, and the Weber-Fechner Law, which relates the size of a physical stimulus change to how large that change is actually perceived to be. A phenomenon whose distortion concerns a judgment, a choice or a memory rather than the raw perception of a stimulus itself is filed under one of the other three groups instead.FactsAll Perception and Psychophysics EffectsSourcesComments (0)Reader Challenges (0)FactsComparisonOriginating WorkWell-attestedGustav Fechner's Elemente der Psychophysik (1860) 1All Perception and Psychophysics EffectsFilter Results226 entriesPhenomenon FamilyAllAuditory Perception Effects (31)Body And Self-Perception Effects (7)Motion And Depth Perception (35)Multisensory And Cross-Modal Effects (2)Other Psychophysics Effects (20)Perceptual Disorders (20)Time Perception Effects (24)Visual Illusions (87)Type of PhenomenonAllBehavioral Phenomenon (2)Cognitive Phenomenon (41)Developmental Phenomenon (1)Emotional Phenomenon (3)Perceptual Phenomenon (177)Branch of PsychologyAllAbnormal Psychology (6)Aviation Psychology (2)Cognitive Neuroscience (4)Cognitive Psychology (114)Cyberpsychology (1)Environmental Psychology (2)Experimental Psychology (3)Neuropsychology (19)Parapsychology (2)Psycholinguistics (5)Psychology of Music (3)Psychophysics (22)Psychophysiology (1)In GroupAllAuditory Perception Effects (31)Body And Self-Perception Effects (7)Motion And Depth Perception (35)Multisensory And Cross-Modal Effects (2)Other Psychophysics Effects (20)Perceptual Disorders (20)Time Perception Effects (24)Visual Illusions (87)First Described EraAll1593 (1)1760 (1)1799 (1)1804 (1)1812 (1)1819 (1)1825 (1)1832 (1)1833 (2)1834 (1)1860 (4)1861 (1)1865 (3)1870 (2)1872 (1)1880 (2)1886 (1)1889 (1)1890 (1)1891 (2)1892 (1)1894 (1)1895 (1)1898 (1)1908 (2)1909 (1)1910 (1)1911 (1)1912 (3)1914 (1)1915 (2)1922 (1)1923 (6)1924 (2)1926 (2)1929 (2)1934 (1)1935 (1)1937 (3)1939 (1)1943 (1)1947 (2)1949 (2)1953 (1)1954 (2)1955 (1)1957 (1)1958 (1)1959 (1)1960 (2)1961 (1)1962 (1)1965 (1)1966 (1)1967 (1)1968 (1)1970 (3)1972 (1)1973 (2)1974 (2)1976 (2)1979 (1)1980 (1)1981 (2)1982 (2)1986 (1)1988 (1)1989 (1)1992 (2)1995 (3)1998 (3)1999 (2)2000 (1)2001 (2)2003 (3)2007 (2)2008 (1)2010 (1)Associated PsychologistAllHermann Ebbinghaus (1)Max Wertheimer (1)Diagnostic ChapterAllDisorders Due to Substance Use or Addictive Behaviours (1)Neurocognitive Disorders (4)Show ResultsBrowseCompareSelect all 50Jastrow IllusionPerception and Psychophysics EffectsJust-Noticeable DifferencePerception and Psychophysics EffectsKanizsa TrianglePerception and Psychophysics EffectsKappa EffectPerception and Psychophysics EffectsKinetic Depth EffectPerception and Psychophysics EffectsKoffka RingPerception and Psychophysics EffectsKuleshov EffectPerception and Psychophysics EffectsLaw of ClosurePerception and Psychophysics EffectsLaw of Common FatePerception and Psychophysics EffectsLaw of ContinuityPerception and Psychophysics EffectsLaw of PragnanzPerception and Psychophysics EffectsLaw of ProximityPerception and Psychophysics EffectsLaw of SimilarityPerception and Psychophysics EffectsLaw of SymmetryPerception and Psychophysics EffectsLawn Dart EffectPerception and Psychophysics EffectsLeaning Tower IllusionPerception and Psychophysics EffectsLexical Bias EffectPerception and Psychophysics EffectsLilac ChaserPerception and Psychophysics EffectsMach BandsPerception and Psychophysics EffectsMandelbaum EffectPerception and Psychophysics EffectsMcCollough EffectPerception and Psychophysics EffectsMcGurk EffectPerception and Psychophysics EffectsMicro-ExpressionPerception and Psychophysics EffectsMicrowave Auditory EffectPerception and Psychophysics EffectsMisophoniaPerception and Psychophysics EffectsMissing FundamentalPerception and Psychophysics EffectsMissing Letter EffectPerception and Psychophysics EffectsMixed Error EffectPerception and Psychophysics EffectsMoon IllusionPerception and Psychophysics EffectsMoses IllusionPerception and Psychophysics EffectsMotion AftereffectPerception and Psychophysics EffectsMotion ParallaxPerception and Psychophysics EffectsMotion-Induced BlindnessPerception and Psychophysics EffectsMüller-Lyer IllusionPerception and Psychophysics EffectsMultistable PerceptionPerception and Psychophysics EffectsNecker CubePerception and Psychophysics EffectsNeural AdaptationPerception and Psychophysics EffectsNumerical Stroop EffectPerception and Psychophysics EffectsNumerosity Adaptation EffectPerception and Psychophysics EffectsOctave IllusionPerception and Psychophysics EffectsOppel-Kundt IllusionPerception and Psychophysics EffectsOrbison IllusionPerception and Psychophysics EffectsOuchi IllusionPerception and Psychophysics EffectsOut-of-Body Experience (Psychology)Perception and Psychophysics EffectsPalinopsiaPerception and Psychophysics EffectsPenrose StairsPerception and Psychophysics EffectsPenrose TrianglePerception and Psychophysics EffectsPerceived Visual AnglePerception and Psychophysics EffectsPerceptual ConstancyPerception and Psychophysics EffectsPerceptual DefensePerception and Psychophysics Effects← Previous12345Next →Sources1.
