We form a quotient when dividing one thing by another. We meet the word frequently when discussing a person s IQ, their intelligence quotient, which we define as (a person s score in an intelligence test 4- the average score) x 100. 

Peabody Picture Vocabulary Test. The Peabody Picture Vocabulary Test is a rapid 10-15-minute intelligence test for children aged 2.5 to 18 years that is useful when there is inadequate time to give the WISC.

Other intelligence tests were considered for use in the RUPP Autism Network studies, but were not chosen for various reasons (Arnold et al., 2000). The Kaufman Assessment Battery for Children (K-ABC) General Cognitive Index is not strictly comparable to an IQ,... 

OSIRIS is another EC project fully dedicated to the REACH legislation [30]. The purposes of OSIRIS are broader than the simple QSAR models. OSIRIS wants to develop an intelligent testing strategy capable to assess whether the data for a certain chemical compound is sufficient or not. We have mentioned that the REACH legislation requires that sufficient data should be provided for a safe use of chemical compounds on the European market. On the basis of the different...

A related question of relevance, particularly to tests of achievement such as the so-called intelligence tests, is standardization. This refers to the population from which the normative scores for the test were collected. This issue is often raised in the interpretation of intelligence tests for populations that are culturally and... 

A recently developed technique for infant assessment is embodied in the Fagan Test of Infant Intelligence, which assesses visual recognition memory. In this test, an infant faces a display with two screens. On one screen, a visual stimulus is presented for a specified period of time. Subsequently, that visual stimulus is projected on one screen and, at the same time, another visual stimulus is projected onto another screen. An observer records the amount of time the infant spends gazing at each screen. Normal infants look away from the visual stimulus which they have already seen and spend more time gazing at the novel stimulus, a trait which has been shown to correlate with higher scores later in development on the Stanford-Binet intelligence test. 

While these developmental and intelligence tests may clearly be important to the determination of the levels and conditions of exposures to a toxicant associated with adverse behavioral function, they are less useful, as noted previously, in providing a precise delineation of the behavioral functions actually affected by a chemical. Measures such as intelligence test scores are global measures in that they rely on the integration of all behavioral functions. Even performances on subscales of these tests are jointly... 

Assessments of behavioral toxicity in adults frequently occur in the context of occupational exposures to chemicals. Like studies carried out in school-aged children, these evaluations have relied largely on standardized tests, including intelligence tests. They also tend to employ a broad variety of tests so that numerous behavioral functions can be tested, particularly when the effects of a toxicant are ill-defined. As such, the same considerations must be taken into account with respect to the choice of tests utilized. These include validity, reliability, and sensitivity, as well as standardization issues related to the population from which test norms were derived. 

Because the Mad Hatter in Alice in Wonderland exhibited some of the symptoms of erethism, he is sometimes held to be a model for the afflictions suffered by workers in the hat industry whether Lewis Carrol intended such a parallel is still disputed, but the resemblances are uncanny. Even in the absence of identifiable symptoms, psychological testing has revealed what could be called nascent erethism in workers exposed to mercury vapor but showing no overt signs of toxicity. Tests of coordination and reaction time reveal differences between exposed and unexposed workers. Performance on elements of adult intelligence tests, such as the ability to repeat strings of digits, also shows differences. 

A general] intelligence test is the single most important test that can be administered for vocational guidance purposes (Humphreys 1985, p211).
