The acquisition of receptive and expressive language skills by students with autism and developmental disabilities (DD) is often delayed, thus making the process of communicating with others challenging. Some students develop language skills incidentally through conversations with their families and peers, but others require instruction in…

Rett syndrome (RTT) is associated with a range of serious neurodevelopmental consequences including severe communicative impairments. Currently, no evidence-based communication interventions exist for the population (Sigafoos et al., 2009). The purpose of the current study was to examine the effectiveness of functional assessment (FA) and…

A review of the literature was conducted for articles published between 2003 and 2010 to build a case for the degree to which evidence-based practices were documented for teaching academic skills to students with severe developmental disabilities. This review extended earlier comprehensive work in literacy, mathematics, and science for the…

Results of a study involving 24 developmentally delayed preschoolers revealed that training on two or fewer exemplars of a stimulus class was sufficient to produce concept acquisition regardless of the training program employed (stimulus fading, stimulus delay, or reinforcement only). (CL)

We describe a training program to teach applied behavior analysis (ABA) knowledge competencies to paraprofessional staff (N = 47) at a habilitation services agency for adults with developmental disabilities. Before and following training, staff completed assessment of knowledge tests for three content areas: basic learning principles,…

In 2 experiments, each involving different mathematical operations, we compared 2 training procedures for teaching component math skills in terms of their effects on the learning and long-term maintenance of composite skill. The dependent variables were learn units to composite task mastery and performance on the composite task 2 months later. The…

Speaker immersion is a tactic that uses multiple establishing operations to increase speaker behavior for individuals with limited mand and tact repertoires. The purpose of this paper was to evaluate the effects of speaker immersion on the number of independent mands, tacts, and autoclitics emitted by young children with verbal delays. In the…

The principle of motivation has resurfaced as an independent variable in the field of behavior analysis over the past 20 years. The increased interest is the result of the refinements of the concept of the motivating operation and its application to the learning needs of persons with developmental disabilities. Notwithstanding the increased…

Intended for use in training conferences, the manual describes the philosophy and procedures of Try Another Way, an approach for teaching moderately, severely and profoundly mentally retarded persons and developmentally disabled persons difficult to train. An alternative definition of retardation is proposed which stresses level of functioning…

Two staff members working in different preschools received training in the form of instructions, modeling, immediate feedback, and social reinforcement of good performance. Effects of training were assessed with a multiple baseline ABCDCDCD design. Correct use of basic behavioral teaching techniques increased from 16-31% to 92-95% and the rate of…

A single subject alternating treatment design was used to compare the effectiveness of embedded and small-group instruction to teach vocabulary word definitions to four middle school students with developmental disabilities. Embedded instruction was implemented in the students' general education classes. Students were taught to verbally define…

This booklet was developed to help in the design and implementation of self-management systems for elementary-classroom students with developmental disabilities. Self-management components addressed in the booklet are self-monitoring, self-evaluation, and self-reinforcement. Chapters provide: (1) the definitions and rationale for teaching…
