Mod 11 Example of a Complex Experimental Design (Sisson & Barrett) Flashcards
The experimental question for this study is best represented by which choice?
What are the effects of oral speech versus total communication training (speech plus sign language) on the ability of mentally retarded children to repeat 4-word sentences?
What is the treatment design outlined in the article?
an alternating treatment design integrated within a multiple baseline design
What are the treatment designs (described in the article) from previous studies comparing oral and total communication training?
a group experimental design and alternating treatment designs
How did the experimental design for baseline differ from the design for treatment?
The therapist did not wait for the child’s full attention during baseline.
No prompts or reinforcers were delivered during the baseline condition.
No prompts or reinforcers were delivered during the treatment condition.
No prompts or reinforcers were delivered during the baseline condition.
What is the behavior of interest in the current study?
noun labeling along with repeated vocalization of 4-word sentences
repeated vocalization of 4-word sentences
repeated vocal and signed 4-word sentences
vocalization of novel sentences
repeated vocalization of 4-word sentences
What are the independent and dependent variables?
The independent variables include the total communication method (verbal communication and sign language), and the oral communication method. The dependent variable is the mean number of sentence parts repeated by the participants.
The procedure included:
Oral methods were used during one session, and total communication methods were used during the other.
During assessment the therapist showed the cue and modeled the response.
After training one sentence, 5 assessment trials were conducted.
all of the above
What population is being studied?
children with intellectual disabilities who had some prebaseline communication skills
What setting is described in the article?
A private therapy room at a psychiatric treatment center
A small therapy room including a table and two chairs, and a one-way observation window
A cubicle at the back of a small classroom, separated by bookcases
A small therapy room including a table and two chairs, and a one-way observation window
Figures 1, 2 and 3 show that:
The results for all three children clearly show the differential effects of treatment.
None of the above
The results for Tyco clearly show the differential effects of treatment.
The results for Mick clearly show the differential effects of treatment.
The results for Mick clearly show the differential effects of treatment.
Reliability measures used resulted in what effect on advancement to criterion levels?
In no case did errors in scoring result in failure to advance or in premature advancement to subsequent criterion levels.
What were the results of the experiment?
Results demonstrated that total communication training was more effective than strictly oral training methods in facilitating sentence repetition for the three subjects in the study.
