Burrhus Frederic Skinner was an American psychologist, behaviorist, inventor, and social philosopher. He was the Edgar Pierce Professor of Psychology at Harvard University from 1958 until his retirement in 1974.
Instructional design (ID), also known as instructional systems design and originally known as instructional systems development (ISD), is the practice of systematically designing, developing and delivering instructional materials and experiences, both digital and physical, in a consistent and reliable fashion toward an efficient, effective, appealing, engaging and inspiring acquisition of knowledge. The process consists broadly of determining the state and needs of the learner, defining the end goal of instruction, and creating some "intervention" to assist in the transition. The outcome of this instruction may be directly observable and scientifically measured or completely hidden and assumed. There are many instructional design models, but many are based on the ADDIE model with the five phases: analysis, design, development, implementation, and evaluation.
Operant conditioning, also called instrumental conditioning, is a learning process where voluntary behaviors are modified by association with the addition of reward or aversive stimuli. The frequency or duration of the behavior may increase through reinforcement or decrease through punishment or extinction.
A toothbrush is a special type of brush used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth. They should be used in conjunction with something to clean between the teeth where the bristles of the toothbrush cannot reach - for example floss, tape or interdental brushes.
In behavioral psychology, reinforcement refers to consequences that increase the likelihood of an organism's future behavior, typically in the presence of a particular antecedent stimulus. For example, a rat can be trained to push a lever to receive food whenever a light is turned on. In this example, the light is the antecedent stimulus, the lever pushing is the operant behavior, and the food is the reinforcer. Likewise, a student that receives attention and praise when answering a teacher's question will be more likely to answer future questions in class. The teacher's question is the antecedent, the student's response is the behavior, and the praise and attention are the reinforcements.
Teeth cleaning is part of oral hygiene and involves the removal of dental plaque from teeth with the intention of preventing cavities, gingivitis, and periodontal disease. People routinely clean their own teeth by brushing and interdental cleaning, and dental hygienists can remove hardened deposits (tartar) not removed by routine cleaning. Those with dentures and natural teeth may supplement their cleaning with a denture cleaner.
Adaptive behavior is behavior that enables a person to cope in their environment with greatest success and least conflict with others. This is a term used in the areas of psychology and special education. Adaptive behavior relates to everyday skills or tasks that the "average" person is able to complete, similar to the term life skills.
Applied behavior analysis (ABA), also called behavioral engineering, is a scientific discipline that applies the principles of learning based upon respondent and operant conditioning to change behavior of social significance. ABA is the applied form of behavior analysis; the other two are radical behaviorism and the experimental analysis of behavior.
Abrasion is the non-carious, mechanical wear of tooth from interaction with objects other than tooth-tooth contact. It most commonly affects the premolars and canines, usually along the cervical margins. Based on clinical surveys, studies have shown that abrasion is the most common but not the sole aetiological factor for development of non-carious cervical lesions (NCCL) and is most frequently caused by incorrect toothbrushing technique.
Systematic desensitization, or graduated exposure therapy, is a behavior therapy developed by the psychiatrist Joseph Wolpe. It is used when a phobia or anxiety disorder is maintained by classical conditioning. It shares the same elements of both cognitive-behavioral therapy and applied behavior analysis. When used in applied behavior analysis, it is based on radical behaviorism as it incorporates counterconditioning principles. These include meditation and breathing. From the cognitive psychology perspective, cognitions and feelings precede behavior, so it initially uses cognitive restructuring.
Shaping is a conditioning paradigm used primarily in the experimental analysis of behavior. The method used is differential reinforcement of successive approximations. It was introduced by B. F. Skinner with pigeons and extended to dogs, dolphins, humans and other species. In shaping, the form of an existing response is gradually changed across successive trials towards a desired target behavior by reinforcing exact segments of behavior. Skinner's explanation of shaping was this:
We first give the bird food when it turns slightly in the direction of the spot from any part of the cage. This increases the frequency of such behavior. We then withhold reinforcement until a slight movement is made toward the spot. This again alters the general distribution of behavior without producing a new unit. We continue by reinforcing positions successively closer to the spot, then by reinforcing only when the head is moved slightly forward, and finally only when the beak actually makes contact with the spot. ... The original probability of the response in its final form is very low; in some cases it may even be zero. In this way we can build complicated operants which would never appear in the repertoire of the organism otherwise. By reinforcing a series of successive approximations, we bring a rare response to a very high probability in a short time. ... The total act of turning toward the spot from any point in the box, walking toward it, raising the head, and striking the spot may seem to be a functionally coherent unit of behavior; but it is constructed by a continual process of differential reinforcement from undifferentiated behavior, just as the sculptor shapes his figure from a lump of clay.
Extinction is a behavioral phenomenon observed in both operantly conditioned and classically conditioned behavior, which manifests itself by fading of non-reinforced conditioned response over time. When operant behavior that has been previously reinforced no longer produces reinforcing consequences the behavior gradually stops occurring. In classical conditioning, when a conditioned stimulus is presented alone, so that it no longer predicts the coming of the unconditioned stimulus, conditioned responding gradually stops. For example, after Pavlov's dog was conditioned to salivate at the sound of a metronome, it eventually stopped salivating to the metronome after the metronome had been sounded repeatedly but no food came. Many anxiety disorders such as post traumatic stress disorder are believed to reflect, at least in part, a failure to extinguish conditioned fear.
Dentin hypersensitivity is dental pain which is sharp in character and of short duration, arising from exposed dentin surfaces in response to stimuli, typically thermal, evaporative, tactile, osmotic, chemical or electrical; and which cannot be ascribed to any other dental disease.
Tooth brushing is the act of scrubbing teeth with a toothbrush equipped with toothpaste. Interdental cleaning can be useful with tooth brushing, and together these two activities are the primary means of cleaning teeth, one of the main aspects of oral hygiene. The recommended amount of time for tooth brushing is two minutes.
Oral hygiene is the practice of keeping one's oral cavity clean and free of disease and other problems by regular brushing of the teeth and adopting good hygiene habits. It is important that oral hygiene be carried out on a regular basis to enable prevention of dental disease and bad breath. The most common types of dental disease are tooth decay and gum diseases, including gingivitis, and periodontitis.
Tact is a term that B.F. Skinner used to describe a verbal operant which is controlled by a nonverbal stimulus and is maintained by nonspecific social reinforcement (praise).
Backward design is a method of designing an educational curriculum by setting goals before choosing instructional methods and forms of assessment. Backward design of curriculum typically involves three stages:
- Identify the results desired
- Determine acceptable levels of evidence that support that the desired results have occurred
- Design activities that will make desired results happen
Response-prompting procedures are systematic strategies used to increase the probability of correct responding and opportunities for positive reinforcement for learners by providing and then systematically removing prompts. Response prompting is sometimes called errorless learning because teaching using these procedures usually results in few errors by the learner. The goal of response prompting is to transfer stimulus control from the prompt to the desired discriminative stimulus. Several response prompting procedures are commonly used in special education research: (a) system of least prompts, (b) most to least prompting, (c) progressive and constant time delay, and (d) simultaneous prompting.
Chaining is a technique used in applied behavior analysis to teach complex tasks by breaking them down into discrete responses or individual behaviors that are part of a task analysis. With a backward chaining procedure the learning can happen in two ways. In one approach the adult can complete all the steps for the learner and give the learner the opportunity to attempt the last one and prompt as needed. For the other approach the adult can prompt the learner throughout the steps on the chain and give the learner an opportunity to complete the last one independently. However, if unable to do so the adult helps by also prompting the learner through the last step and reinforcement is given to the learner once the last step is completed. Because independency is desired the goal is to remove the prompts as soon as the learner can complete the steps without help.
The Picture Exchange Communication System (PECS) is an augmentative and alternative communication system developed and produced by Pyramid Educational Consultants, Inc. PECS was developed in 1985 at the Delaware Autism Program by Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP. The developers of PECS noticed that traditional communication techniques, including speech imitation, sign language, and picture point systems, relied on the teacher to initiate social interactions and none focused on teaching students to initiate interactions. Based on these observations, Bondy and Frost created a functional means of communication for individuals with a variety of communication challenges. Although PECS was originally developed for young children with autism spectrum disorder (ASD), its use has become much more widespread. Through the years, PECS has been successfully implemented with individuals with varying diagnoses across the aged span. PECS is an evidence-based practice that has been highly successful with regard to the development of functional communication skills.
