Effects of equal and unequal reinforcer duration during functional analysis

Area of Science:

• Behavior analysis
• Applied behavior analysis
• Functional analysis methodology

Background:

• The standard functional analysis (FA) methodology by Iwata et al. (1982/1994) often involves varying reinforcer durations across conditions.
• This variation, such as brief attention versus extended escape, may lead to unequal exposure to establishing operations.
• Establishing operations influence the motivation for specific behaviors, including aberrant behaviors.

Observation:

• This study investigated the impact of reinforcer duration consistency within functional analyses.
• The research specifically compared outcomes under conditions of unequal versus equal reinforcer durations.
• The primary objective was to determine if reinforcer duration influences the rate of aberrant behavior.

Findings:

• Results indicated that reinforcer duration significantly affects the rate of aberrant behavior observed during functional analyses.
• Unequal reinforcer durations were found to potentially alter the interpretation of functional analysis outcomes.
• The duration of reinforcement is a critical variable that needs careful consideration in FA design.

Implications:

• Findings suggest that inconsistent reinforcer durations can lead to inaccurate conclusions about the function of aberrant behavior.
• Methodological adjustments in functional analysis, ensuring equal reinforcer duration, may be necessary for precise assessment.
• This research underscores the importance of controlling extraneous variables, like reinforcer duration, for reliable behavior analysis.
