Increasing "Object-Substitution" Symbolic Play in Young Children With Autism Spectrum Disorders

Object-centered family interactions for young autistic children: a diary study

Autistic Children often struggle with social interaction and communication, studies have found that many of them prefer to interact with objects than people. However, there is a lack of research exploring the specific characteristics and factors involved in interactions within families with autistic children where objects are the center of the interaction. This paper describes the process and findings of a diary study exploring how young autistic children interact with their families through objects in natural scenarios. A one-week diary study was conducted with six families with young autistic children. Diary videos were recorded onsite and coded later according to a social interaction behavior scheme with corresponding diary entries. Qualitative data analysis was conducted to reveal possible patterns. Results revealed ongoing difficulties in establishing and maintaining family interaction and identified influential factors of object-centered family interaction. The most prevalent pattern observed was parents taking the lead in interactions, followed by the child's confirmation response. Remarkably, daily necessities emerged as potential physical mediums for enhancing family interactions, opening avenues for exploring tangible designs in human-computer interaction. These findings offer valuable implications for future research and the development of innovative designs that promote enriching interactions for autistic children and their families.

Symbolic Play among Children with Autism Spectrum Disorder: A Scoping Review

Symbolic play is considered an early indicator in the diagnosis of autism spectrum disorder (ASD) and its assessment. The objective of this study was to analyze the difficulties in symbolic play experienced by children with ASD and to determine the existence of differences in symbolic play among children with ASD, children with other neurodevelopmental disorders and children with typical development. A scoping review was carried out in the Web of Science (WoS), Scopus, ERIC, and PsycInfo databases, following the extension for scoping reviews of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The number of papers included in the review was 22. The results confirm that children with ASD have greater difficulties with symbolic play than children with other neurodevelopmental disorders and children with typical development, even when controlling for their verbal age. Difficulties are greater in situations of free or spontaneous play. Results evidenced that the absence or deficiency in the symbolic play can serve as an early indicator of ASD between the first and second year of life, the developmental moment in which this type of play begins.

Improving pretend play for children with autism through experiencing the stimulus properties of real objects

Children with autism spectrum disorder (ASD) often lack symbolic play skills. Attribution of pretend properties (APP) is a type of symbolic play in which a child tacts pretend properties of an object (e.g., smelling a toy flower and saying, "It smells like a rose!"). Three Chinese boys (5-6 years of age) with ASD served as participants. A multiple-probe design across 5 objects was used to determine the effects of an intervention that involved having the child experience and tact sensory properties of real objects (e.g., rose). Corresponding test objects, including mock (e.g., a toy flower) and arbitrary objects (e.g., a stick), were used to evaluate whether tact responses for sensory properties were transferred. Results indicated that all 3 children emitted tacts of stimulus properties for test objects and maintained the skill for 7 to 10 weeks following the intervention. Two participants also tacted novel (nontarget) properties for test objects.

Arranging play activities with missing items to increase object-substitution symbolic play in children with autism spectrum disorder

PURPOSE

Many children with autism spectrum disorder do not have symbolic play skills. The purpose of this study was to evaluate the effects of a training procedure on the acquisition, maintenance, and generalization of object-substitution symbolic play in children with autism spectrum disorder.

METHODS

A single-case experimental design (multiple-probe across four behaviors) was used. One girl (5 years) and two boys (4-5 years) participated in this study. The training procedure involved withdrawing necessary items in play activities, supplying multiple substitutes, and providing hierarchical assistive prompts. Each child's symbolic play responses across baseline, intervention, and follow-up conditions were recorded and graphed. Data analysis involved visual inspection of graphs.

RESULTS

The results indicated that the procedure effectively increased and maintained object-substitution symbolic play. Generalization to untaught play activities occurred in all children, and symbolic play increased in the free play setting for one child.

CONCLUSIONS

Arranging play activities with missing items increased opportunities for children to engage in symbolic play. The training procedure can be used in clinical and educational settings as an initial step to establish and improve complex play behavior in children with autism spectrum disorder who lack such skills.IMPLICATIONS FOR REHABILITATIONMany children with autism spectrum disorder have inappropriate play behaviors and do not demonstrate symbolic play.Arranging play activities with missing items and systematic assistive prompts effectively increased object-substitution symbolic play.Generalization of symbolic play to untrained play activities occurred after the intervention.

Increasing Response Diversity to Intraverbals in Children with Autism Spectrum Disorder

The purpose of this study was to evaluate the effects of intraverbal prompts on response diversity and novelty in intraverbals posed to children with autism spectrum disorder (ASD). The intraverbal prompts involving function, feature, and class (FFC) of an item were used in the training of three questions requiring multiple responses. Two Chinese boys with ASD (aged 5-6 years) served as participants. A multiple-probe across three behaviors design was employed. The results indicated that the intraverbal prompts effectively increased the number of divergent responses to all three questions. Novel responses emerged at a low level while generalization to similar questions was not observed following the training.

Teaching "Imaginary Objects" Symbolic Play to Young Children with Autism

Symbolic play skills are important in language acquisition and child development. Children with autism spectrum disorder (ASD) often have difficulties demonstrating such play behaviors. Imaginary objects symbolic play refers to play behavior in which children perform play actions without actual objects. Three boys with ASD (3-7 years) participated in this study. A multiple-probe across three participants and two settings design was employed to evaluate the effects of intraverbal training on the acquisition and generalization of imaginary objects symbolic play. Results indicated that all children acquired and maintained target imaginary objects play activities. Generalization to untaught activities occurred in one child. All three children' symbolic play emerged or increased in free play after the instruction.
