Barbeau, Soulières, Dawson, Zeffiro and Mottron (2012) conducted an experiment to examine the correlation of autistic individuals’ intelligence between their intelligence level and their intelligence examination time. The goal of the experiment was to compare inspection time (IT) between people on the autistic spectrum and some control typical groups, and to determine whether or not early speech development is related to these statistics (Barbeau, et al., 2012). The results were expected to be that the autistic group would outperform the typical group in a Wechsler IQ test regarding their IT and would be very similar to the performance of the typical group on the Raven’s Progressive Matrices (RPM, a test of reasoning ability that doesn’t need …show more content…

The autistic samples were randomly selected from the Autism Specialized Clinic at Rivière-des-Prairies Hospital in Montreal, Canada (Barbeau et al., 2012). These people had to be over the age of 14 and have a Wechsler full-scale IQ score over 75, and were not allowed to have “uncorrected visual impairment, use of illegal drugs, or use of alcohol exceeding two drinks per day” (Barbeau et al. 2012, p. 297). Typical participants were chosen via a questionnaire that showed that they had no experience with any conditions (neurological, psychiatric, or medical) that affected brain function (Barbeau et al., 2012). The autistic and Asperger participants were further separated into seven subgroups, each involving the age at which they went through certain speech development stages (Barbeau et al., …show more content…

With regard to the autistic groups’ performance against Wechsler IQ-matched and RPM-matched groups of typical people, the superior performance to the former group and equal performance to the latter supported the experimenter’s theory that the Wechsler IQ test underestimated autistic people’s general intelligence (Barbeau et al., 2012). The fact that the earlier age of first phrases throughout the Asperger groups corresponded to their RPM performance was also well-received, as it proved that this age statistic greatly affects Wechsler IQ test results (Barbeau et al., 2012). Both of these results combined completely proved their original theory, and thus added more evidence to the overall theory that people with autism and Aspergers have very comparable abilities to typical people (Barbeau et al.,
