Thurstone stated Weber's law as follows: " The stimulus increase which is correctly discriminated in any specified proportion of attempts ( except 0 and 100 per cent ) is a constant fraction of the stimulus magnitude " ( Thurstone, 1959, p. 61 ).

The psychometrician L. L. Thurstone, founder and first president of the Psychometric Society in 1936, developed and applied a theoretical approach to measurement referred to as the law of comparative judgment, an approach that has close connections to the psychophysical theory of Ernst Heinrich Weber and Gustav Fechner.

In addition, Spearman and Thurstone both made important contributions to the theory and application of factor analysis, a statistical method developed and used extensively in psychometrics.

Figures who made significant contributions to psychometrics include Karl Pearson, Henry F. Kaiser, L. L. Thurstone, Georg Rasch, Eugene Galanter, Johnson O ' Connor, Frederic M. Lord, Ledyard R Tucker, Arthur Jensen, and David Andrich.

In 1937 Thorndike became the second President of the Psychometric Society, following in the footsteps of Louis Leon Thurstone who had established the society and its journal Psychometrika the previous year.

Typically attitude tests use either a Thurstone scale, or Likert Scale to measure specific items.

* Thurstone scale – This is a scaling technique that incorporates the intensity structure among indicators.

Since that early time, however, other researchers ( e. g., Cattell, Guilford, and Thurstone ) have argued that intellect cannot be expressed in such a unitary manner, and have suggested more multifaceted approaches to intelligence.

In psychology, the Thurstone scale was the first formal technique for measuring an attitude.

It was developed by Louis Leon Thurstone in 1928, as a means of measuring attitudes towards religion.

Even though the theory behind this method is quite complex ( Thurstone, 1927a ), the algorithm itself is straightforward.

In particular, Thurstone showed that if Fechner's law applies and the discriminal dispersions associated with stimuli are constant ( as in Case 5 of the LCJ outlined below ), then Weber's law will also be verified.

The underlying rationale for the method and basis for the measurement of the " psychological scale separation between any two stimuli " derives from Thurstone's Law of comparative judgment ( Thurstone, 1928 ).

* Thurstone, L. L. ( 1927b ) The method of paired comparisons for social values.

He soon extended the domain of application of the law of comparative judgment to things that have no obvious physical counterpart, such as attitudes and values ( Thurstone, 1929 ).

* Thurstone — Earth-like dry world, with three nations, one of which is Santiago ( non-industrial Spanish Catholic-ethnic w / involuntary colonists ).

The scale is then obtained as a left-adjusted column marginal average of this standard score matrix ( Thurstone, 1927b ).

Although Thurstone referred to it as a law, as stated above, in terms of modern psychometric theory the ' law ' of comparative judgment is more aptly described as a measurement model.

Early in the history of the school Mackey noted " Basic to our teaching and organization is the Thurstone Psychological Examination.

Thanks again to dumping of colonists from Earth, the Santiago colony on Thurstone has progressed to de facto slavery by debt bondage in order to maintain social order.

Thurstone published a paper on the law of comparative judgment in 1927.

This contrasts with topics studied using a Likert scale or a Thurstone scale.

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.

To be considered a ' hack ' was an honour among like-minded peers as " to qualify as a hack, the feat must be imbued with innovation, style and technical virtuosity " ( Levy, 1984 p. 10 ) The MIT's Tech Model Railroad Club Dictionary defined hack in 1959 ( not yet in a computer context ) as " 1 ) an article or project without constructive end ; 2 ) a project undertaken on bad self-advice ; 3 ) an entropy booster ; 4 ) to produce, or attempt to produce, a hack ( 3 ).
