Premack gave the children two response alternatives, eating candy or playing a pinball machine, and determined which of these behaviors was more probable for each child. Some of the children preferred one activity, some the other. In the second phase of the experiment, the children were tested with one of two procedures.
The Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) is an assessment and skills-tracking system to assess the language, learning and social skills of children with autism or other developmental disabilities. A strong focus of the VB-MAPP is language and social interaction, which are the predominant areas of weakness in ...
Reinforcement occurs when the consequence of a behavior makes it more likely for that behavior to occur in the future. Reinforcing consequences can be either positive, where something preferred is added, or negative, where something aversive is removed. [63] Reinforcement is the key element in operant conditioning and most behavior change programs.
The revised assessment of basic language and learning skills (ABLLS-R) is an assessment tool, curriculum guide, and skills-tracking system used to help guide the instruction of language and critical learner skills for children with autism or other developmental disabilities.
For children, some of these variables could set the pattern for lifelong problems. For example, a child whose depressive behavior functions for negative reinforcement by stopping fighting between parents could develop a lifelong pattern of depressive behavior in the case of conflicts.

Researchers have found that about a quarter of kids diagnosed with autism are severely affected; these children are often minimally or non-speaking or require extensive assistance for basic daily ...
Ole Ivar Løvaas (8 May 1927 – 2 August 2010) [1] [2] was a Norwegian-American clinical psychologist and professor at the University of California, Los Angeles.He is most well known for his research on what is now called applied behavior analysis (ABA) to teach autistic children through prompts, modeling, and positive reinforcement.
The training protocol is based on the principles of applied behavior analysis. [3] The goal of PECS is spontaneous and functional communication. [3] The PECS teaching protocol is based on B. F. Skinner's book, Verbal Behavior, such that functional verbal operants are systematically taught using prompting and reinforcement strategies that will lead to independent communication.
