I chose this article because I wanted to take a deeper look
into Sign Language being used as a language intervention. This study focused on
utilizing manual sign mand training when used with a prompt delay procedure.
Prompt delay procedures consist of offering the desired item to the child and
waiting three to five seconds before prompting the child to sign or say the
name of the item.
The results of the study found that using prompt delays
followed by vocal prompt paired with sign language increases the likelihood of
vocal responses. The study also stated that these procedures could be utilized
without the use of manual sign language, however they found that using sign
language initially improves the use of functional language communication.
