description - ANSWER enhances the understanding of a given phenomenon. Descriptive
knowledge consists of a collection of facts about the observed events that can be
quantified, classified, and examined for possible relations with other known facts.
prediction - ANSWER occurs when repeated observations reveal that two events consistently
covary with each other. When in the presence of one event another event occurs with some
specified probability.
control - ANSWER the highest level of scientific understanding. When you are able to arrange
conditions and manipulate the environment.
Momentary Time Sampling - ANSWER the observer marks down whether or not the
behavior was occurring at the moment the interval ended.
Whole Interval Recording - ANSWER the observer records whether the target behavior occurred
throughout the entire interval; tends to underestimate the proportion of the observation
period that many behaviors actually occurred.
Partial Interval Recording - ANSWER a time sampling method in which the observer records
whether the target behavior occurred at any time during the interval.
planned activity check (PLACHECK) - ANSWER a variation of momentary time sampling in
which the observer records whether each person in a group is engaged in the target behavior
at specific points in time; provides a measure of "group behavior"
, Interobserver Agreement (IOA) - ANSWER The degree to which 2 or more independent
observers report the same observed values after measuring the same events
total count IOA - ANSWER Smaller count/Larger count x 100 = %
observer reactivity - ANSWER any measurement error that comes from an observers
knowledge that others are evaluating the data that they report
observer drift - ANSWER Any unintended change in the way an observer uses a
measurement system over the course of an investigation that results in measurement error.
Topography - ANSWER is the physical form or shape of behavior. It describes behavior—
specifically what the behavior looks like. defines instances of the targeted response class by
the shape or form of the behavior. Specifically what behavior looks like.
magnitude - ANSWER The force or intensity with which a response is emitted.
measurement by permanent product - ANSWER measuring behavior after it has occurred by
measuring the effects that the behavior produced on the environment.
arbitrary stimulus class - ANSWER contains stimuli that evoke the same response but do
not share a common physical feature
Stimulus/Prompt Salience - ANSWER refers to how obvious or prominent a stimulus is in a
person's environment. If a person has visual deficits, then visual stimulus will not have as much
salience as auditory stimulus, for example.
stimulus equivalence - ANSWER the emergence of accurate responding to untrained and
nonreinforced stimulus-stimulus relations following the reinforcement of responses to some
stimulus-stimulus relations.In other words, it is when two forms of reinforced teaching lead to
a third concept that was not taught or reinforced
