The Relationship between Semantic Joke and Idiom Comprehension in Adolescents with Autism Spectrum Disorder.

Semantic jokes involve resolving an incongruity emerging from wordplay or from a violation of world knowledge. The research has shown individuals with autism spectrum disorder (ASD) demonstrate a lower performance on humor tasks involving social situations; however, less is known about their semantic joke comprehension. This study examines semantic joke comprehension among adolescents with ASD and its possible relationship to vocabulary size, theory of mind (ToM), and idiom comprehension.

Verbal and Figural Creativity in Children With Autism Spectrum Disorder and Typical Development.

Previous studies have shown that individuals with autism spectrum disorder (ASD) demonstrate lower performance on creativity tasks. Yet, recent findings suggest that individuals with ASD are not necessarily impaired in verbal creativity, as measured by the novel metaphor generation task. The current study investigates verbal and figural creativity in 40 children with ASD (aged 11-14 years) and 39 peers with typical development (TD) (aged 11-15 years).

Elucidating the role of selective attention, divergent thinking, language abilities, and executive functions in metaphor generation.

Metaphoric language is one of the most common expressions of creative cognition in everyday life. However, the cognitive mechanisms underlying metaphor generation remain largely unexplained. In this study, we aimed to investigate the relationship between various cognitive functions and both novel and conventional metaphor generation.

Comprehension and Generation of Metaphoric Language in Children, Adolescents, and Adults with Dyslexia.

Difficulties with figurative language comprehension were documented in adult dyslexia (DYS). In the present research, we investigated the comprehension and generation of metaphors in 37 children, 35 adolescents, and 34 adults with and without DYS. We also tested the contribution of executive function to metaphor processing.

Verbal creativity in autism: comprehension and generation of metaphoric language in high-functioning autism spectrum disorder and typical development.

Studies on creativity in participants with autism generally show impoverished performance as well as deficient comprehension of metaphoric language. However, very little is known about the ability to generate metaphors in this population. The present study examines verbal creativity in adults with autism-spectrum disorder (ASD) through tasks that rely on novel metaphoric language.

The relationship between visual metaphor comprehension and recognition of similarities in children with learning disabilities.

Previous studies have shown metaphoric comprehension deficits in children with learning disabilities. To understand metaphoric language, children must have enough semantic knowledge about the metaphorical terms and the ability to recognize similarity between two different domains. In the current study visual and verbal metaphor understanding was assessed in 20 children with learning disabilities (LD) and 20 typically developed (TD) children.

Principal component analysis study of visual and verbal metaphoric comprehension in children with autism and learning disabilities.

This research extends previous studies regarding the metaphoric competence of autistic and learning disable children on different measures of visual and verbal non-literal language comprehension, as well as cognitive abilities that include semantic knowledge, executive functions, similarities, and reading fluency. Thirty seven children with autism (ASD), 20 children with learning disabilities (LD), and 21 typically developed (TD) children participated in the study. Principal components analysis was used to examine the interrelationship among the various tests in each group.

Thinking maps enhance metaphoric competence in children with autism and learning disabilities.

The primary goal of the current study was to examine the ability of children with autism (ASD) and children with learning disabilities (LD) to improve their metaphoric competence by an intervention program using "thinking maps". Twenty ASD children, 20 LD, and 20 typically developed (TD) children were tested on metaphors and idioms comprehension tests, homophone meaning generation test, and fluency tests. Both ASD and LD groups performed poorly compared with TD on all tests, with the LD group outperformed the ASD group in the executive function tests.
