The scale is then obtained as a left-adjusted column marginal average of this standard score matrix (Thurstone, 1927b). 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).
A Thurstonian model is a stochastic transitivity model with latent variables for describing the mapping of some continuous scale onto discrete, possibly ordered categories of response. In the model, each of these categories of response corresponds to a latent variable whose value is drawn from a normal distribution , independently of the other ...
The BTL model is identical to Thurstone's model if the simple logistic function is used. Thurstone used the normal distribution in applications of the model. The simple logistic function varies by less than 0.01 from the cumulative normal ogive across the range, given an arbitrary scale factor.
That is, the scale represents how heavy people perceive the objects to be based on the comparisons. 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. It represents a general theoretical model which, applied in a ...

Psychometrics is a field of study within psychology concerned with the theory and technique of measurement.Psychometrics generally covers specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. [1]
The Thurstone Word Fluency Test, also known as the Chicago Word Fluency Test (CWFT), [1] was developed by Louis Thurstone in 1938. [2] This test became the first word fluency psychometrically measured test available to patients with brain damage. [3] The test is a used to measure an individual's symbolic verbal fluency.
Hamilton Rating Scale for Anxiety (HAM-A) Unlike most other psychological symptom scales listed in this section, clinicians use this scale to help evaluate the mental health of people, usually under treatment, who have been diagnosed with an anxiety disorder; it is not used with the general population samples.
