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…
Differential Reinforcement of Other Behavior (DRO)
Differential Reinforcement of Other Behavior (DRO) is a procedure in which reinforcement is delivered dependent on the absence of the target behavior (Conyers, Miltenberger, Romaniuk, Kopp, & Himle, 2003). DRO results in a decrease in the identified target behavior because…
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…
Mentoring the New Generation
There are key defining differences between a mentorship and a supervisory relationship, the most salient being that a successful relationship between the mentor and the protégé is bidirectional. Mentoring pertains to the identification and development of the protégé’s personal and professional potential.…
Telehealth ABA
Telehealth is defined as the use of electronic information and telecommunications technologies to support long-distance clinical health care, patient and professional health-related education, public health and health administration. Given the outstanding need for services for individuals with ASD and other…
Barriers to Being a Good BCBA
With funding for services changing and many states/provinces requiring more services in fewer hours, it can be discouraging to implement behavior analysis with integrity. Common barriers we face as BCBAs are : Funding Time constraints Large caseloads Limited support/resources So…
So you didn’t pass the BCBA exam…
As the August exam results are published, emotions run high. Some may be celebrating their new certification while others prepare to study for the next round. This post is for those who will prepare once again for the big exam.…
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…
