The P > V sign on the WISC-R and recidivism in delinquents.

Verbal/performance splits in inmates assessed with the multidimensional aptitude battery

“…In a study of recidivism in delinquent male adolescents, Haynes and Bensch (1981) found that the P > V differences were present significantly more often in the recidivist group than in the non-recidivists, whose intellectual profiles did not differ significantly from those of normals. Tarter, Hegedus, and Winsten (1984) addressed the P > V proposition further by questioning whether those delinquents with left-hemisphere inferiority relative to right-hemisphere functioning are also more inclined to a violent pattern of antisocial behavior.…”

“…Until recently, studies of intelligence that required verbal and performance scores generally have been restricted to the results that could be obtained through individually administered tests of intelligence, such as the Wechsler series (Haynes & Bensch, 1981;Henning & Levy, 1967;Sutker, Moan, & Allain, 1984;Tarter et al, 1984), but a relatively new test of intelligence, the Multidimensional Aptitude Battery (MAB; Jackson, 1984), shows promise for obtaining information about intelligence through a group-administered test. The subtens of the MAB are purported to be analogous to the WAIS-R subtests, so the format is familiar to most professionals, but unlike its individually administered model, the MAB uses an objective multiple choice scoring format, which makes the recording of scores a clerical task rather than a subjective clinical one.…”

The Human Adolescent Brain and Alcohol Use Disorders

“…Conduct disorder and related circumstances (e.g., juvenile delinquency, antisocial personality disorder, disruptive behavior disorders, neurobehavioral disinhibition) have been associated with an increased risk of alcohol and other drug use disorders (Tarter et al, 2003), as well as neurocognitive disadvantages. These youths tend to perform poorly on academic achievement (Fuerst & Rourke, 1993) and IQ (Moffitt & Silva, 1988a) tests, and are more likely to demonstrate higher Performance IQ than Verbal IQ (Dgry, Toupin, Pauze, Mercier, & Fortin, 1999;Haynes & Bensch, 1981;Lynam, Moffitt, & Stouthamer-Loeber, 1993;Moffitt, 1993;Prentice & Kelly, 1963;West & Farrington, 1973). Recent studies have shown poor performances on nonverbal tests as well (Toupin, DQy, Pauze, Mercier, & Fortin, 2000).…”

WISC-III and KAIT results in adolescent delinquent males

“…A frequent topic of researchers is the relationship of psychopathic behavior and delinquency to the P > V profile on the various versions of Wechsler's intelligence tests. David Wechsler first noted the P > V profile 50 years ago (Wechsler, 1944) and subsequent researchers have generally confirmed the frequency of its occurrence (Bleker, 1983;Haynes & Bensch, 1981;Matarazzo, 1972). Studies of adult prison inmates found only a 3-112 point difference between Verbal and Performance IQs (Kender, Greenwood, & Conard, 1985).…”
