Case Scenario:

An instructor conducted a study to determine if pointing to pictures of items in books while reading to children will increase their tacting (labeling) skills.
Participant and setting description:

Three children participated in the study
Sessions took place after school in the participants' home.
Target behavior and Tact Trial description:

The instructor implemented "tact trials" in which the instructor sat across the table from the participant and help up a picture card and say, "What's this?".
A "correct" response occurred if the participant emitted the correct tact (label) for the item in the picture.
An "incorrect" response occurred if the participant did not respond or responded incorrectly.
Baseline description:

During baseline sessions, the instructor held up a picture card and said, "what's this?" with no prompts or reinforcement.
Intervention session description:

During intervention sessions, the instructor read books to the participant earlier in the day. The books contained pictures of the same items in the picture cards used during tact trials later that day.
The instructor used a multiple probe across participants design
Data were collected in the same manner during baseline and intervention conditions.
The instructor marked "correct" if the participant emitted the correct tact (label) for the item in the picture during tact trials.
The instructor marked "incorrect" if the participant did not respond or responded incorrectly during tact trials.
The instructor calculated the percent or correct response per session.
Internal validity was strong and experimental control was displayed.
All participants responded at 0% during baseline sessions and showed slow, but consistent improvement after the intervention was introduced.
Data in generalization and maintenance phases prove that the intervention was effective.
