Behavior analyst
+ Applied behavior analysis, Analyzing Behavior, Data collection
  * Frequency is how often a behavior happens. So frequency recording just counts the number of times a behavior happens. Every time a behavior happens it is recorded by the observer. Frequency data is easy to collect so it is used a lot. Behavior analysts use frequency data to determine rate of response. Rate of response is the number of responses for a specific time period. To find rate of response, the frequency is divided by the total time of the observation. For example if the target behavior happened 100 times in 10 hours the rate of response would be 10 times per hour. Rate of response is the best measure of how often behavior happens.
  * Interval recording breaks the observation time into smaller pieces. The total time is divided into smaller intervals. If the behavior happens at any time during one of the smaller intervals it is recorded. But only one behavior per interval is recorded. So the total number of behaviors is not recorded. Behavior analysts can get an idea of how often the behavior occurs with interval recording. Interval measurements will not be as accurate as frequency measurements. It can also be hard to measure behavior using intervals. It can be hard because the observer has to keep track of the intervals. To do this the observer must be paying attention the entire time
  - Characteristics, Analytic
  * This means they have to be able to make the behavior happen at certain times. There are two ways that behavior analysts can prove they have control over a behavior. Both ways involve the use of an experimental variable. Behavior analysts will change part of the environment that they think will cause a change in behavior. The part of the environment that they change is the experimental variable. Behavior analysts have to show that the variable they used is what caused the change in behavior. To do this they have to compare data from before they applied the variable to data they collected after they applied the variable. The data from before the experimental variable is applied is called baseline data
+ Applied behavior analysis, Definitions and concepts, Reinforcement schedules
  * Reinforcements are given based on schedules of reinforcement. The schedule will explain the ways reinforcement is earned. Behavior analysts decide which reinforcement schedule is best. Different schedules are useful for different things. The schedule used depends on the person. It also depends on the behavior that is being reinforced
  - Three-term contingency
  * It is the response to the behavior. So, an antecedent happens before a behavior and a consequence happens after a behavior. Keeping track of antecedents, behaviors, and consequences is called taking ABC data. If the same thing always happens before or after a behavior it can help behavior analysts find cause of that behavior. ABC data is not enough to prove the cause of a behavior. Behavior analysts have to use experimental variables to prove the cause of a behavior. But ABC data can be used to find things that may be causing behavior. Then these causes can be tested using experimental variables
