Summary
Latency to the first aberrant response is a useful dependent measure for selecting preferred stimuli in forced-choice preference assessments. This method aids in identifying stimuli for effective treatment planning.
Area of Science:
- Behavioral science
- Applied behavior analysis
Background:
- Preference assessments are crucial for identifying motivating stimuli in applied behavior analysis.
- Traditional methods may not always capture the full spectrum of stimulus preference.
Purpose of the Study:
- To evaluate the utility of latency to the first aberrant response as a dependent measure in forced-choice preference assessments.
- To compare this measure with approach responding for stimulus selection.
Main Methods:
- A forced-choice preference assessment was employed.
- Two dependent measures were recorded: approach responding and latency to the first aberrant response.
- Stimuli selected based on both measures were evaluated during treatment.
Main Results:
- Latency to the first aberrant response demonstrated utility in identifying preferred stimuli.
- This measure, alongside approach responding, contributed to stimulus selection.
Conclusions:
- Latency to the first aberrant response is a valuable and potentially more sensitive measure for preference assessments.
- Incorporating latency measures can enhance the precision of stimulus selection for treatment.
