Henry Weber Biography

The interpretation of Weber Weber Ernst Henry is a German anatomist and physiologist, one of the founders of scientific psychology. A foreign corresponding member of the St. Petersburg Academy of Sciences conducted research primarily in the physiology of the senses: hearing, vision, and skin sensitivity. He studied the effect of temperature adaptation. The analysis of touch allowed him to distinguish three types of skin sensations: a feeling of pressure and touch, temperature sensations, and a feeling of localization.

He developed a scheme for an experimental study of touch, for which he designed a special device “Aesthesiometer”, or “Circular Weber”, with the help of which he evaluated the distance, sufficient so that the two touch to the surface of the skin did not merge in one sensation. In these studies, V. in the city was reflected by him in the following formula: where J is the initial stimulus, DJ is the difference between the new stimulus from the original, to the constant, depending on the type of receptor.

Based on these studies, G. Fechner, the formula of the Basic Law of Psychophysics was derived: the sensation changes in proportion to the logarithm of the stimulus cm. Weber-Fechner Law. Brief psychological dictionary. Karpenko, A. Petrovsky, M. Weber Weber Ernst Henry with G. conducted research in the physiology of the senses: hearing, vision, and skin sensitivity.

He studied the effect of temperature adaptation: if you first place one hand in cool water and the other in hot, then warm water after that will seem to be warmer than the second than for the second. The analysis of the touch "On touch" allowed him to distinguish three types of skin sensations: a feeling of pressure or touch, temperature sensations, and a feeling of localization.

In these studies, Weber determined that this distance is different for various areas of the skin the so -called “sensation circles” and, therefore, the skin has different sensitivity. Fehner was bred by the formula of the Basic Law of Psychophysics: the sensation changes in proportion to the Logarithm of the irritant, the law of Weber-Fechner. In addition, Weber expressed interesting considerations about the sensitivity of early childhood for bilateral transfer of motor skills, he himself had the ability to draw mirror images at the same time with both hands.
