Societal expectations for social-emotional behavior differ across sexes; however, diagnostic definitions of autism do not account for this when delineating "typical" versus "atypical." This study examines sex differences in autism in one behavior associated with strong gender biases: smiling. Computer vision was used to…

Literature underlines the social stigma frequently connected to children with SLD associated with vulnerability to social exclusion and lower socio-emotional competencies. Consequently, they may internalise this biased perspective, affecting their sense of self and behaviour in social contexts. The present study aims to explore socio-emotional…

Teacher rating scales (TRS) are often used to make service eligibility decisions for exceptional learners. Although TRS are regularly used to identify student exceptionalism either as part of an informal nomination process or through behavioral rating scales, there is little research documenting the between-teacher variance in teacher ratings or…

Overidentification of minority students in special education is a significant concern. It is imperative that the districts effectively train professionals who administer testing for qualification of special education. The purpose of this qualitative case study was to discover why minority students are disproportionately enrolled in special…

Teacher-report is commonly used to assess executive functions (EFs) in schools, but teachers' perceptions of EF skills may be biased by students' demographic characteristics. In this short-term longitudinal study, we assessed whether students' gender, ethnicity, and English language learner (ELL) status predicted teachers' reports of students'…

Background: It is now widely known that children with severe intellectual disability show a 'floor effect' on the Wechsler scales. This effect emerges because the practice of transforming raw scores into scaled scores eliminates any variability present in participants with low intellectual ability and because intelligence quotient (IQ) scores are…

A common finding in studies of differential prediction across groups is that although regression slopes are the same or similar across groups, group differences exist in regression intercepts. Building on earlier work by Birnbaum (1979), Millsap (1998) presented an invariant factor model that would explain such intercept differences as arising due…

On the basis of several reviews of the literature, Lynn [Lynn, R., (2006). Race differences in intelligence: An evolutionary analysis. Augusta, GA: Washington Summit Publishers.] and Lynn and Vanhanen [Lynn, R., & Vanhanen, T., (2006). IQ and global inequality. Augusta, GA: Washington Summit Publishers.] concluded that the average IQ of the…

Despite the fact that disability has been recognized as "a natural part of the human experience" (Developmental Disabilities Assistance and Bill of Rights Act of 2000) and that the Education for All Handicapped Children Act of 1975 and its later reauthorizations as the Individuals with Disabilities Education Act (IDEA) should have served…

The Wechsler intelligence test has four factors representing four components of intellectual function. In China, there are marked cultural, educational, and economic disparities between rural and urban dwellers, which could lead to cultural bias. The aim of this study was to apply the four-factor structure to responses to the Chinese Intelligence…

Background: Previous research with earlier versions of the WISC and WAIS has demonstrated that when administered to people who have intellectual disabilities, the WAIS produced higher IQ scores than the WISC. The aim of this study was to examine whether these differences still exist. A comparison of the Wechsler Adult Intelligence Scale-Third…

Several items from the Information and Comprehension subtests of the Wechsler Intelligence Scale for Children were cited by Judge Grady in his opinion in the PASE (Parents in Action in Special Education) case as being culturally biased against Black children. Error analysis showed no significant "cultural" differences between White and…

Criteria were developed to assess sexual and racial item content bias for every item from six IQ tests. Each reference was judged as either stereotyped or not sterotyped. This analysis pointed out an overwhelming sexual and racial imbalance in item content. (Author/RL)

Examines the Eurocentric basis of the Wechsler Intelligence Scale for Children--Third Edition (WISC-III) and reveals its antagonistic and incompatible relationship to an Africentric conception of intellectual and mental health. Suggests that the WISC-III provides a measure of misorientation quotient rather than intelligence quotient, and notes…

Updates previous literature reviews by reporting recent findings about the Wechsler Intelligence scales and other performance tests with American Indians. Discusses test bias and the unwitting role of clinical psychologists in preserving the American Indian status quo through testing. Suggests ways to increase awareness of responsible and ethical…
