Backward Chaining (applied Behavior Analysis)
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.

Chaining
Chaining is a type of intervention that aims to create associations between behaviors in a behavior chain. A behavior chain is a sequence of behaviors that happen in a particular order where the outcome of the previous step in the chain serves as a signal to begin the next step in the chain. In terms of behavior analysis, a behavior chain is begun with a discriminative stimulus In behavioral psychology (or applied behavior analysis), stimulus control is a phenomenon in operant conditioning (also called contingency management) that occurs when an organism behaves in one way in the presence of a given stimulus and another w ... (SD) which sets the occasion for a behavior, the outcome of that behavior serves as a reinforcer for completing the previous step and as another SD to complete the next step. This sequence repeats itself until the last step in the chain is completed and a terminal reinforcer (the outcome of a behavior chain, i.e. with brushing one's teeth the terminal reinfor ...

Applied Behavior Analysis
Applied behavior analysis (ABA), also called behavioral engineering, is a psychological intervention that applies empirical approaches based upon the principles of respondent and operant conditioning to change behavior of social significance.See also footnote number "(1)" of nd the whole "What is ABA?" section of Where the same definition is given, (or quoted), and it credits (or mentions) both the source "Baer, Wolf & Risley, 1968" (Drs.

Tooth Brushing
Tooth brushing is the act of scrubbing teeth with a toothbrush, usually equipped with toothpaste. Interdental cleaning (with floss or an interdental brush) 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. History Teeth-cleaning twigs have long been used throughout human history. As long ago as 3000 B.C., the ancient Egyptians constructed crude toothbrushes from twigs and leaves to clean their teeth. Similarly, other cultures such as the Greeks, Romans, Arabs and Indians also cleaned their teeth with twigs. Some would fray one end of the twig so that it could penetrate between the teeth more effectively. The Indian method of using wood for brushing was presented by the Chinese Monk Yijing (635–713 A.D.) when he described the rules for monks in his book: Modern-day tooth brushing as a regular habit became prevalent in Europe from the end of the 17th century. The first mas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backward Chaining
Backward chaining (or backward reasoning) is an inference method described colloquially as working backward from the goal. It is used in automated theorem provers, inference engines, proof assistants, and other artificial intelligence applications. In game theory, researchers apply it to (simpler) subgames to find a solution to the game, in a process called ''backward induction''. In chess, it is called retrograde analysis, and it is used to generate table bases for chess endgames for computer chess. Backward chaining is implemented in logic programming by SLD resolution. Both rules are based on the modus ponens inference rule. It is one of the two most commonly used methods of reasoning with inference rules and logical implications – the other is forward chaining. Backward chaining systems usually employ a depth-first search strategy, e.g. Prolog. How it works Backward chaining starts with a list of goals (or a hypothesis) and works backwards from the consequent to the ...
