    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…

    Response-Deprivation Hypothesis

    The Premack principle states that contingent access to higher-probability behavior (preferred activities) reinforces lower-probability behavior Premack, 1959 The term “response-deprivation hypothesis”, an extension of Premack’s relative value theory, refers to a model for predicting whether access to one behavior (the…

    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…
