I used an adapted alternating treatments design to compare the effectiveness and efficie
ncy of a 5_s constant time delay and a simultaneous prompting procedure on teaching rea
d grocery sight words to students with autism.
A multiple probe design across subjects was used to evaluate the effectiveness of the
procedure.
Both 5_s constant time delay and a simultaneous prompting procedure were effective o
n teaching read grocery sight words.
Data indicate that the simultaneous prompting procedure was more efficient on measure
s of acquisition and the 5_s constant time delay was more efficient on measures of maint
enance and generalization.
However, the simultaneous prompting procedure was more efficient than 5_s constant
time delay in terms of the number of training errors and training time through criterion.
Discussion focuses on the differing acquisition, maintenance, and generalization data, a
nd student's near-errorless learning. Future research is need to support these findings.
