Children with autism spectrum disorder (ASD) attend typically to faces and objects presented within their picture communication systems

Children with autism spectrum disorder (ASD) may require interventions for communication difficulties. One type of intervention is picture communication symbols which are proposed to improve comprehension of linguistic input for children with ASD. However, atypical attention to faces and objects is widely reported across the autism spectrum for several types of stimuli. In this study we used eye-tracking methodology to explore fixation duration and time taken to fixate on the object and face areas within picture communication symbols. Twenty-one children with ASD were compared with typically developing matched groups. Children with ASD were shown to have similar fixation patterns on face and object areas compared with typically developing matched groups. It is proposed that children with ASD attend to the images in a manner that does not differentiate them from typically developing individuals. Therefore children with and without autism have the same opportunity to encode the available information. We discuss what this may imply for interventions using picture symbols.

Enhancing the Alternative and Augmentative Communication Use of a Child with Autism through a Parent‐implemented Naturalistic Intervention

The effects of a parent‐implemented naturalistic intervention on the communication skills of a 4‐year‐old boy with autism using an alternative and augmentative communication (AAC) system were investigated. The child’s mother was taught to use 4 naturalistic teaching strategies that incorporated a picture communication system during 2 typical home routines. Generalisation probes to assess the caregiver’s use of the intervention techniques and generalisation of the child’s communication outcomes were conducted in 2 similar interactions. A multiple baseline design was used to evaluate the effects of the intervention. Data indicated an increase in the use of 2 caregiver–teaching strategies across two routines following treatment. No consistent changes were observed in the use of the other caregiver strategies across the routines. An increase in the child’s frequency of initiations and responses and the use of the communication system also were observed.

Transparency and Recall of Symbols among Intellectually Handicapped Adults

The purpose of this investigation was to examine the transparency and recall of symbols representing three parts of speech (nouns, verbs, descriptors) from three different graphic symbol systems (Blissymbols, Picture Communication System, and Picsyms) among adults with intellectual handicaps. Results suggested that the Picture Communication System (PCS) and Picsyms were more transparent and easier to learn than Blissymbols. Subjects correctly identified significantly fewer Blissymbols representing nouns than either PCS or Picsyms representing nouns. In early stages of recall for nouns, PCS and Picsyms were significantly easier to recall than Blissymbols. Implications of the data for symbol system selection use for persons with severe speech impairments are discussed.
