This study aimed to compare cognitive and memory abilities between older adults with and without autism over the age of 50. Twenty-eight individuals with autism and 29 typically developing (TD) older adults took part in the current study. Participants' cognitive and memory abilities were assessed by WAIS-IV and WMS-IV. Older autistic adults were…

Social perception is important because it can affect the way intelligence is expressed during social interactions at school, home, and work. This study (N = 800) of adolescents and adults (age range = 16-91) examined which specific aspects of intelligence are associated with social perception (a composite of affect labelling, linking prosody to…

Individuals with autism spectrum disorder (ASD) present difficulties in forming relations among items and context. This capacity for relational binding is also involved in spatial navigation and research on this topic in ASD is scarce and inconclusive. Using a computerised version of the Morris Water Maze task, ASD participants showed particular…

Language learners have to acquire the phonological grammar of their native language, and different levels of representations on which the grammar operates. Developmental dyslexia is associated with a phonological deficit, which is commonly assumed to stem from degraded phonological representations. The present study investigates one aspect of the…

Adolescent cannabis use is associated with working memory impairment. The present randomized controlled trial assigned adolescents ages 14 to 21 enrolled in cannabis use treatment to receive either working memory training (experimental group) or a control training (control group) as an adjunctive treatment. Cognitive function, drug use, and other…

There is accumulating evidence that training on working memory (WM) generalizes to other nontrained domains, and there are reports of transfer effects extending as far as to measures of fluid intelligence. Although there have been several demonstrations of such transfer effects in young adults and children, they have been difficult to demonstrate…

The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory…

The present study focuses on examining the hypothesis that auditory temporal perception deficit is a basic cause for reading disabilities among dyslexics. This hypothesis maintains that reading impairment is caused by a fundamental perceptual deficit in processing rapid auditory or visual stimuli. Since the auditory perception involves a number of…

Previous research using the Wechsler scales has identified areas of cognitive weaknesses in children, adolescents, and adults diagnosed with Autism or Asperger's syndrome. The current study evaluates cognitive functioning in adolescents and adults diagnosed with Autism or Asperger's syndrome using the Wechsler Adult Intelligence Scale-Fourth…

The present study investigates the performance of persons with reading disabilities (PRD) on a variety of sequential visual-comparison tasks that have different working-memory requirements. In addition, mediating relationships between the sequential comparison process and attention and memory skills were looked for. Our findings suggest that PRD…

Relational frame theory (RFT) explicitly suggests that derived relational responding underlies complex verbally-based cognitive performances. The current study investigated whether the ability to respond in accordance with temporal relations between stimuli was predictive of performance on the four indices of the Wechsler Adult Intelligence Scale,…
