Background:

Autism Spectrum Disorder (ASD) is characterized by challenges in social communication and interaction.
Spontaneous verbalizations are crucial for social reciprocity in children with ASD.
Effective interventions are needed to enhance functional language skills in autistic individuals.

Purpose of the Study:

To investigate the efficacy of a time delay procedure in increasing spontaneous verbalizations in young children with ASD.
To assess the generalization of learned verbalizations across different stimuli and settings.
To evaluate the social validity of the intervention and its impact on inappropriate speech.

Main Methods:

A time delay procedure was implemented with three autistic children.

Related Experiment Videos

A multiple baseline across behaviors design was utilized.

Target behaviors included spontaneous "please," "thank you," and prompted "you're welcome."

Main Results:

All three children demonstrated significant gains in target spontaneous verbalizations.
The intervention led to generalization of these behaviors across various stimuli and settings.
Social validation by adults confirmed the appropriateness of the increased verbalizations.
No increase in inappropriate speech was observed.

Conclusions:

The time delay procedure is an effective method for increasing spontaneous and prompted verbalizations in autistic children.
Intervention gains generalized, indicating robust learning.
The procedure is socially valid and does not negatively impact other communication behaviors.
