Assessment,Graphing, Ethics Flashcards
What is continous recording?
Observer observes the client continuously throughout the observation period and records each occurrence of the behavior. to do so the observer must be able to identify the onset and offset of each instance of the behavio. observer can record various dimensions of the target behaviour such as frequency, duration, intensity and latency.
Frequency
The number of times behavior occurs in the observation period.
Duration
Total amount of time occupied by the behavior from start to finish
Rate
responses per minute. (frequency divided by the time of observation period)
Real time recording
Method which the exact time of each onset of the target behavior is recorded. (usually done using video)
intensity
amount of force, energy, or exertion involved in the behavior (also called magnitude)
latency
time from some stimulus or event to the onset of the behavior
How does latency differ from behavior?
latency is the time from some stimulus or event to the onset of the behavior, whereas duration is the time from the onset of the behavior to its offset. That is, latency is how long it takes to start the behavior and duration is how long the behavior lasts.
Percentage of trials or percentage correct
is one final way in which event record- ing may be conducted. In this method, the observer records the occurrence of a behavior in relation to some other event, such as a learning trial or a response opportunity, and reports the results as the percentage of opportunities in which the behavior occurred.
Product recording
an indirect assessment method that can be used when a behavior results in a certain tangible outcome that you are interested in. It is an indirect measure because you are not observing and recording the behavior as it occurs. One benefit of product recording is that the observer does not have to be present when the behavior occurs.
interval recording.
the observer divides the observation period into a number of smaller time periods or intervals, observes the client throughout each consecu- tive interval, and then records whether the behavior occurred in that interval. At the end of the observation period, the observer reports the percentage of intervals in which the behavior was observed (the number of intervals in which behavior occurred divided by the number of intervals in the observation period).
What are the two types of interval recording?
partial-interval recording and whole- interval recording.
partial-interval recording
the observer scores the interval if the behavior occurred during any part of the interval.
whole-interval recording
the occurrence of the behavior is marked in an interval only when the behavior occurs throughout the entire interval. If the behavior occurs in only part of the interval, the behavior is not scored as occurring in that interval.
frequency-within-interval recording.
Frequency-within-interval recording shows you the frequency of the behavior and the specific intervals in which the behavior occurred.
