Study Notes
Preference Assessments Overview
- Preference assessments identify an individual's favorite items to use as effective rewards for behavior reinforcement.
- Common assessment methods include caregiver interviews, surveys, and direct observation.
Types of Preference Assessments
- Single Item/Stimulus: Evaluates individual items one at a time.
- Forced Choice/Paired Stimulus: Presents two items simultaneously for selection.
- Multiple Choice: Involves selecting from a group of items, with or without replacement.
- Indirect Assessment: Gathers information from people familiar with the individual.
- Free Operant: Observes choices made by a learner in an unrestricted environment.
Indirect Preference Assessment
- Relies on insights from parents, friends, and teachers to determine the individual's preferences.
Free Operant Preference Assessment
- Involves observing a learner's choices when free access to various activities or items is available, documenting preferred objects for potential reinforcement.
Single Stimulus Preference Assessment
- Each stimulus is presented for a duration of 2 minutes, tracking both acceptance of the item and the playtime duration for assessing preferences.
Forced Choice Preference Assessment
- Participants choose between two simultaneous items or activities, aiding in identifying the most frequently selected item as a powerful reinforcer.
Multiple Stimuli Without Replacement
- After selection, the chosen item is removed, rearranging the remaining items for further choice assessment, reducing the item array progressively.
Multiple Stimuli With Replacement
- The selected item remains available for future choices, with the items rearranged for subsequent trials, maintaining the total number of options.
Reinforcers
- Defined as pleasant events following a behavior that enhance the likelihood of the behavior's future occurrence, examples include candy, praise, or a special toy.
Data Collection in Single Stimulus Preference Assessments
- Key data types collected include duration of interaction, percentage of time spent, count of interactions, and overall outcome validity.
Hierarchy of Preference Challenges
- Establishing a hierarchy of preference is complex during a single stimulus assessment since the learner engages without making comparative choices.
