    Calculating IOA

    Interobserver agreement (IOA) indicates the percentage of agreement between two or more observers recording the same event. It is important in assessing the integrity of data collection. IOA is most commonly used when training a new observer, periodically to increase…

    Behavior Cusps

    Successful behavior analytic programming focuses on the implementation of evidence-based procedures to address socially significant behaviors. Behavioral cusps is a behavior change that has consequences beyond the change itself. Rosales-Ruiz & Baer (1997) As practitioners of applied behavior analysis, we…

    Baseline Logic

    Baseline logic consists of three elements (prediction, verification, and replication) that depend on an overall approach of steady state strategy. Steady state strategy: repeated exposure to a condition, controlling for extraneous variables, and obtaining a stable pattern before introducing the…

    Changing Criterion Design

    Changing Criterion Design – analyzes the effects of an independent variable across multiple behaviors/settings/participants (dependent variable) without having to withdraw the treatment. Types of Changing Criterion Design Increasing rates of behavior Decreasing rates of behavior Guidelines Length of phases: should…

    Multiple Baseline Design

    Multiple Baseline Design – analyzes the effects of an independent variable across multiple behaviors/settings/participants (dependent variable) without having to withdraw the treatment. Types of Multiple Baselines Multiple baseline across behaviors Multiple baseline across settings Multiple baseline across participants Other variations…

    Alternating Treatments Design

    Alternating treatments design (i.e., multielement design) – the rapid alternation of comparing two or more treatments (i.e., independent variable) while measuring the effects on the target behavior (i.e., dependent variable). Types of ATD Single-phase without a no-treatment control condition Single-phase…

    Reversal/Withdrawal Design

    Reversal/Withdrawal Design – repeated measures of behavior between two treatments (reversal) or a treatment and baseline (withdrawal) Distinction between reversal and withdrawal Reversal Design: reversing between treatments (e.g., baseline, treatment, NCR, treatment, NCR, treatment, etc.) Withdrawal Design: reversing between treatment…
