The Thematic Apperception Test (TAT) is a projective psychological test developed during the 1930s by Henry A. Murray and Christiana D. Morgan at Harvard University. Proponents of the technique assert that subjects' responses, in the narratives they make up about ambiguous pictures of people, reveal their underlying motives, concerns, and the ...
Mental chronometry is one of the core methodological paradigms of human experimental, cognitive, and differential psychology, but is also commonly analyzed in psychophysiology, cognitive neuroscience, and behavioral neuroscience to help elucidate the biological mechanisms underlying perception, attention, and decision-making in humans and other ...
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 ...
However the perception is different: On the left side, the difference between upper and lower square is clearly visible. On the right side, the two squares look almost the same. The Weber–Fechner laws are two related scientific laws in the field of psychophysics , known as Weber's law and Fechner's law .
Although the perception of time is not associated with a specific sensory system, psychologists and neuroscientists suggest that humans do have a system, or several complementary systems, governing the perception of time. [15] Time perception is handled by a highly distributed system involving the cerebral cortex, cerebellum and basal ganglia. [16]
Wonderlic test: The Wonderlic test is a multiple choice test consisting of 50 questions within a 12-minute time frame. Throughout the test, the questions become more and more difficult. The test is used to determine not only the individuals intelligence quotient, but also the strengths and weaknesses of the individual.
Hermann Rorschach created the inkblot test in 1921. (Photo from c. 1910). The use of interpreting "ambiguous designs" to assess an individual's personality is an idea that goes back to Leonardo da Vinci and Botticelli. [9]
