| Abstract: This symposium will present a single case study of a male child with Autism. This child had significant difficulties acquiring and retaining tacts of common objects and pictures of common objects, improving intelligibility of vocal mands and improving overall intelligibility in the echoic repertoire. The child attended a private ABA clinic in Austin, Texas 6 hours per week. Therapy was conducted by a BCABA and a therapist with a Master’s in Special Education soon sitting for her BCBA. Therapy was supervised by a BCBA.
To improve the acquisition and retention of tacts, two methods were compared. Echoic to tact transfers and a manual sign with vocal prompt. Three tact stimuli were taught in sets of three in an alternating treatment design with each method in a random order. Aims were set for 1 minute timings of correct/incorrect and acquisition and retention data were taken across 9 sets.
To improve the intelligibility of the student’s manding repertoire, specifically two targets that had a strong history of reinforcement, two methods were compared. Trials were conducted using a manual sign plus a vocal prompt and differential reinforcement. Then mand trials were run using Kaufman and Kasper’s Sign and Say kit. This kit provided sound shell syllables to shape articulation within the mand. Data was taken each session on percentage of adult form mands at item and most frequently used sound shell syllables. Acquisition rates and intelligibility were compared.
To improve intelligibility within the echoic repertoire, two procedures were compared in an alternating treatment design. This replicated a symposium presented by Dr. Vince Carbone at ABAI, Atlanta, 2006. A traditional verbal imitation program was run where the child was presented with the adult form of a word three times using differential reinforcement to select out the best approximation or the adult form word. Then using the same pattern of words (CVCV, CVC, VCV), Kaufman’s Speech Praxis Kit was used to provide sound shell syllable break downs also using differential reinforcement. The two methods were compared to see which one resulted in the fasted acquisition rate. |

To improve the acquisition and retention of tacts, two methods were compared. Echoic to tact transfers and a manual sign with vocal prompt. Three tact stimuli were taught in sets of three in an alternating treatment design with each method in a random order. Attempts were made to make sure each stimulus was comparable in their form and familiarity. Aims were set for 1 minute timings of correct/incorrect and acquisition and retention data were taken across 9 sets over several months. |
