Observational studies of retarded children with multiple stereotyped movements
Insights
Activity type significantly impacts stereotyped movements in developmentally delayed children. Environmental factors and adult interactions also influence these repetitive behaviors, showing individual differences.
Area of Science:
- Developmental Psychology
- Behavioral Analysis
- Childhood Development
Background:
- Stereotyped movements are common in children with developmental delays.
- Understanding the environmental triggers for these behaviors is crucial but limited.
- Variability in stereotypies suggests environmental influences.
Purpose of the Study:
- To investigate how different activities and settings affect stereotyped movements in preschool children.
- To explore the relationship between adult-child interactions and stereotyped behaviors.
- To identify environmental factors influencing the frequency of stereotypies.
Main Methods:
- Conducted three observational studies with seven preschool children exhibiting stereotypies.
- Recorded behavior rates during various school activities and settings.
- Analyzed adult-child interactions and employed a sequential model for environmental analysis.
Main Results:
- Activity type significantly influenced the rates of stereotyped behavior, with individual differences noted.
- Variability in stereotypies was observed across different sessions within the same setting.
- Adult interactions differed quantitatively and qualitatively between stereotyping and non-stereotyping children.
- Teacher behaviors were identified as affecting the frequency of aberrant behaviors.
Conclusions:
- Environmental factors, particularly activity type and adult interactions, play a significant role in modulating stereotyped movements.
- Understanding these environmental influences can inform interventions for children with developmental delays.
- Further research into the functional interrelationships of multiple stereotypies is warranted.
Abstract:
Stereotyped movements, such as body rocking and hand gesturing, are common among developmentally delayed children. However, very little is known concerning the naturally occurring circumstances that produce variability in this type of responding. Three relatively long-term observational studies, involving seven preschool children, each of whom exhibited multiple stereotypies, were conducted to determine the extent to which the type of activity or setting had any effect upon the rates of these responses. Repeated observations were made of each child during a variety of school activities. In two studies, adult-child interactions were also recorded. The results showed that, in general, the particular activity greatly affected rates of stereotyped behavior, although there were some marked individual differences. Moreover, in two studies variability was apparent across sessions within a particular setting. For some of the children, there was evidence that their multiple stereotypies were functionally interrelated. Adult interactions, as recorded in one study, appear to be both quantitatively and qualitatively different for stereotyping as contrasted with nonstereotyping children. An environmental analysis employing a sequential model indicated that there were teacher behaviors that affected the frequency and/or conditional probability of the child's aberrant behavior.
