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.
Pivotal response treatment is a naturalistic intervention model derived from the principles of applied behavior analysis.Rather than target individual behaviors one at a time, PRT targets pivotal areas of a child's development such as motivation, [3] responsiveness to multiple cues, [4] self-management, and social initiations. [5]
Behavior modification is a treatment approach that uses respondent and operant conditioning to change behavior. Based on methodological behaviorism, [1] overt behavior is modified with (antecedent) stimulus control and consequences, including positive and negative reinforcement contingencies to increase desirable behavior, as well as positive and negative punishment, and extinction to reduce ...
The standard model is that depression has multiple paths to develop. It can be generated by five basic processes, including: lack or loss of positive reinforcement, [107] direct positive or negative reinforcement for depressive behavior, lack of rule-governed behavior or too much rule-governed behavior, and/or too much environmental punishment ...
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.
In turn, the strict sense of "reinforcement" refers only to reward-based conditioning; the introduction of unpleasant factors and the removal or withholding of pleasant factors are instead referred to as "punishment", which when used in its strict sense thus stands in contradistinction to "reinforcement". Thus, "positive reinforcement" refers ...
Reinforcement is particularly effective in the learning environment if context conditions are similar. [33] Recent research indicates that behavioral interventions produce the most valuable results when applied during early childhood and early adolescence. [34] Positive reinforcement motivates better than punishment.
The behavior is strengthened by an automatic reinforcing consequence. An example of automatic positive reinforcement would be an autistic child waving his hands in front of his face (problem behavior) because the sensory stimulation (automatic positive reinforcement) produced is reinforcing for the child.
