Ole Ivar Lovaas (1927-2010) is known worldwide for his research within the field of Applied Behavior Analysis, and is probably the most influential researcher within the field of treatment of children with autism. In the first part of this biographically oriented paper, we inform the readers about his family background, childhood, elementary and…

Discrete trial teaching (DTT) is one of the cornerstones of applied behavior analysis (ABA) based interventions. Conventionally, DTT is commonly implemented within a prescribed, fixed manner in which the therapist is governed by a strict set of rules. In contrast to conventional DTT, a progressive approach to DTT allows the therapist to remain…

Five individuals with autism or other developmental disabilities participated in paired-stimulus preference assessments during repeated baseline probes. All subjects initially showed a pronounced bias by typically selecting the stimulus placed in either the left or right position. Biased responding for 3 subjects was eliminated when training…

The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

This article presents an introduction to "The Behavior-Analytic Origins of Constraint-Induced Movement Therapy: An Example of Behavioral Neurorehabilitation," by Edward Taub and his colleagues (Taub, 2012). Based on extensive experimentation with animal models of peripheral nerve injury, Taub and colleagues have created an approach to overcoming…

Amid the novel terms and original analyses in Skinner's "Verbal Behavior", the importance of his discussion of multiple control is easily missed, but multiple control of verbal responses is the rule rather than the exception. In this paper we summarize and illustrate Skinner's analysis of multiple control and introduce the terms "convergent…

Recent mandates related to the implementation of evidence-based practices for individuals with autism spectrum disorder (ASD) require that autism professionals both understand and are able to implement practices based on the science of applied behavior analysis (ABA). The use of the term "applied behavior analysis" and its related concepts…

In the United States and throughout the world, one's understanding of autism and other related disorders continues to evolve. Parents, educators, and health professionals today benefit from significant advancements in both the diagnosis and treatment of autism. However, the need to evaluate and select from a list of treatment options can be…

Quantitative behaviour analysis requires the classification of behaviour to produce the basic data. This can be challenging when the theoretical taxonomy does not match observational limitations, or if a theoretical taxonomy is unavailable. Binary keys allow qualitative observation to be used to modify a theoretical taxonomy to produce a practical…

The number of children with autism served in early intervention or the public school system appears to be growing at an alarming rate. This article provides a basis for understanding this dramatic increase. In addition, the authors present a brief overview of the characteristics of autism, research on early behavioral indicators of infants and…

We tested the effect of a Rotated Protocol Immersion package on the emergence of observing responses as prerequisites for more complex verbal developmental capabilities. Three elementary aged students between the ages of 6 and 7 participated. They were diagnosed with autism spectrum disabilities. The treatment condition consisted of total…

The escalating numbers of people identified with autism and other pervasive developmental disorders has resulted in a corresponding increase in the demand for behavior specialists who can direct and conduct applied behavior analytic interventions. There are, however, severe shortages in professionals who can deliver quality services. In this…

The paper uses both the author's experience of research training, and the empirical studies of autism in which he participated over the last 40-plus years, to derive research lessons and to consider the needs and prospects for future research. Attention is drawn to: the importance of mentors; the need to use technologies in a hypothesis-testing…

Social stories were developed in order to support individuals with autism to better cope with social situations, an area of particular difficulty for this population. Despite its growing popularity, there is limited research evidence on the effectiveness of this approach. A review of research on social stories undertaken between 1994 and 2004 was…

Describes a behavior analytic program for preschool children with autism, the University of California, Los Angeles, Young Autism Project. It reviews outcome data, replication and dissemination efforts, frequently voiced concerns, and future directions. It concludes that, based on existing scientific evidence, increasing the availability of…
