- :OK, I trimmed down a little bit the Weber-Fechner law.
- Suggestion that human perception works rather generally on a logarithmic scale is called Weber Fechner law.
- Below these thresholds subjective constancy is experienced in accordance with the Stevens'power law and Weber Fechner law.
- This makes sense in contexts where the Weber Fechner law applies, such as in visual or auditive perception.
- This can be modeled by the Weber-Fechner law : I = a ?log ( c ) + b
- The most famous outcome of his inquiries is the law known as the Weber Fechner law which may be expressed as follows:
- Some of our senses operate in a logarithmic fashion ( Weber Fechner law ), which makes logarithmic scales for these input quantities especially appropriate.
- He considered that the Weber-Fechner law and the LCJ both involve a linear measurement on a psychological continuum whereas Weber's law does not.
- There is a new branch of the literature on public finance hypothesizing that the Weber Fechner law can explain the increasing levels of public expenditures in mature democracies.
- The Weber Fechner law and methods described by L . L . Thurstone are generally applied in local psychophysics, whereas Stevens'methods are usually applied in global psychophysics.
- The human perception of the intensity of sound and light approximates the logarithm of intensity rather than a linear relationship ( Weber Fechner law ), making the dB scale a useful measure.
- Another key difference is that Weber's law and the LCJ involve proportions of comparisons in which one stimulus is judged greater than another whereas the so-called Weber-Fechner law does not.
- The rationale behind this is that a small difference is negligible if the average luminance is high, while the same small difference matters if the average luminance is low ( see Weber Fechner law ).
- In Pogson's time this was thought to be true ( see Weber Fechner law ), but it is now believed that the response is a power law ( see Stevens'power law ).
- No consideration is needed of possible nonlinearities such as the Weber-Fechner law, potential noise in the system, continuously varying angles at the joints, and many other factors that could afflict performance if this were a simple linear model.
- Thus time perception is like the perception of lights, sounds, and other sensory events, where accuracy also is relative to the size ( brightness, loudness, etc . ) of the percept being judged . ( See Weber-Fechner law .)
- In addition, Thurstone employed the approach to clarify other similarities and differences between Weber's law, the Weber-Fechner law, and the LCJ . An important clarification is that the LCJ does not " necessarily " involve a physical stimulus, whereas the other'laws'do.
- Thurstone showed that in terms of his conceptual framework, Weber's law and the so-called Weber-Fechner law, which are generally regarded as one and the same, are independent, in the sense that one may be applicable but not the other to a given collection of experimental data.
- In terms of Thurstone's conceptual framework, the association posited between perceived stimulus intensity and the physical magnitude of the stimulus in the Weber-Fechner law will only hold when Weber's law holds " and " the just noticeable difference ( JND ) is treated as a unit of measurement.
