Objective: ADHD is subject to stigma from the general population. Exposure to stigma poses the risk of developing self-stigma of youth and parents, but few studies have focused on self-stigma of ADHD. Furthermore, parental factors have been implicated in self-stigma of youth, but no previous research has assessed the association between…

Drawing tasks are frequently used to test competing theories of visuospatial skills in autism. Yet, methodological differences between studies have led to inconsistent findings. To distinguish between accounts based on local bias or global deficit, we present a simple task that has previously revealed dissociable local/global impairments in…

In this study only bias in scoring, controlling for the effect of actual administration, was investigated. Results indicated that scoring the WISC was biased by scorers' expectations, and that the bias effect exists independent of actual administration of the test. (Author)

In 1965, McCay Vernon drove a stake through the heart of the long-established "truth" that deaf people were inferior to hearing people. Launched by Aristotle, emboldened by the 1880 Conference of Milan, and reiterated in the twentieth century through the biased research of many psychologists, this falsehood persisted until the publication of this…

Experimenter bias effects were experimentally manipulated in a sample of 97 school psychologists scoring 3 subscales (Similarity, Vocabulary, and Comprehension) of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III). First year (n=29), interns (n=42), and experienced (n=26) psychologists were randomly assigned to either a bias or…

Using the Guide to the Assessment of Test-Session Behavior for the WISC-III and WIAT (GATSB), observations were recorded for 969 children between the ages of 6 and 16 years. Children who exhibited higher levels of avoidance, inattentiveness and uncooperative behaviors while being tested tended to exhibit lower WISC-III scores. (RJM)

Many variables mitigate against a culture-fair test being devised. The Queensland Test--which has been administered to Aboriginal children--is probably fairer than most IQ tests, although it appears to measure the degree of contact with Western culture (implying socio-economic variables) rather than mental and chronological age or cognitive…
