An accurate assessment of cognitive abilities in populations that differ from the majority in cultural and linguistic characteristics is one of the main challenges in cognitive testing. Previously developed methods for assessment of the validity of cognitive scores in individuals with diverse backgrounds, such as the Culture-Language…

An examination of gender-related differential item functioning was conducted on the verbal subtests of the Anadolu-Sak Intelligence Scale. Analyses were conducted using the scale standardization data (N = 4641). A Mantel-Haenszel statistic was used to detect differential item functioning (DIF). A total of 58 verbal analogical reasoning items, 20…

A court decision in California, Larry P. v. Riles (1979) case, ruled in favor of African American students who were disproportionately and wrongly placed in special education (E.M.R. -- educable mentally retarded) classes. Standardized intelligence tests were biased, discriminatory and failed to identify the academic need to support African…

Individually administered intelligence measures are commonly used in diagnostic work, but there is a continuing need for research investigating possible test bias among these measures. One current intelligence measure, the Differential Ability Scales, Second Edition (DAS-II), is a test with growing popularity. The issue of test bias, however, has…

Cognates are known to facilitate second language acquisition and use, as learners tend to assign to a new L2 word the meaning of a similar L1 word. Consequently, for L2 tests that rely largely on lexical items, performance may prove inflated for examinees whose L1 shares many cognates with the language being tested. This article examines the…

The European Union has seen an increased number of asylum seekers and economic migrants over the past few years. There will be request to assess some of these individuals to see if they have an intellectual disability (ID). If this is to be done using the current internationally recognized definitions of ID, we will need to be confident that the…

Other than being African American, little is known of Larry, the lead plaintiff in the legal case known as "Larry P. v. Riles" in 1971, which banned the use of standardized intelligence testing on African-American students in the State of California. As a result of such intelligence testing, Larry was diagnosed as being mildly mentally…

Background: Dynamic testing has been proposed as a testing approach that is less disadvantageous for children who may be potentially subject to bias when undertaking conventional assessments. For example, those who encounter high levels of test anxiety, or who are unfamiliar with standardized test procedures, may fail to demonstrate their true…

A little over 35 years have passed since the original "Larry P." decision was handed down in 1979 by Robert Peckham, a federal judge for the US District Court for the Northern District of California. The "Larry P. case" is a shorthand moniker that refers to a class action lawsuit, supported by the Bay Area Association of Black…

This study investigated whether measures of verbal working memory are less sensitive to children's socioeconomic background than traditional vocabulary measures. Participants were 120 school beginners, divided into high and low socioeconomic groups. The groups contained equal numbers of English first-language and second-language speakers. All were…

This research investigates key psychometric properties of the French Early Years Evaluation-Teacher Assessment measure designed to systematically assess kindergarten children across five social and academic developmental domains: awareness of self and environment, social skills and behaviour, cognitive abilities, language and communication, and…

The 1979 landmark case of "Larry P. v. Riles" continues to be one of the most debated topics in school psychology. In this case, Judge Peckham ruled that standardized, norm-referenced intelligence tests were culturally biased towards African-Americans, resulting in overrepresentation of African-Americans in Educably Mentally Retarded…

The linguistic demand of spoken instructions on individually administered norm-referenced psychological and educational tests is of concern when examining individuals who have varying levels of language processing ability or varying cultural backgrounds. The authors present a new method for analyzing the level of verbosity, complexity, and total…

Standardized tests are used widely in comparative studies of clinical populations, either as dependent or control variables. Yet, one cannot always be sure that the test items measure the same constructs in the groups under study. In the present work, 460 participants with intellectual disability of undifferentiated etiology and 488 typical…

Every widely used psychological assessment instrument is under scrutiny in terms of cultural fairness. The expectation of the reduced-language (Nonverbal) section of the Stanford-Binet Intelligence Scales, Fifth Edition (SB5; Roid, 2003) is that language ought not to be a modifying factor in terms of final score. The purpose of the present study…
