Latency measures the time between the discriminative stimuli (SD) and the response. Click here to view latency recording example. Latency recording measures the amount of time that lapses between an antecedent (e.g., teacher’s directive) and when the student begins to perform a specified behavior. Journal of Applied Behavior Analysis, 46(1), 208-­218. With a longer latency, however, a team could consider reinforcement strategies contingent upon a fixed interval of time completing a non-preferred task (Premack principle). The percentage of trials in which problem behavior occurred, rather than rate of responding during a 10-minute trial as in the traditional FA, is then used in order to develop a functional hypothesis for the problem behavior. In the first case, there is very little time to intervene after a transition but before a problem behavior, so teaching strategies and contrived practice with transitioning would be the best choice. LATENCY:The time it takes for a behavior to occur following the antecedent. Latency recording can tell you whether a student is getting better at starting to work on in-class assignments when prompted to begin working, preparing for class activities, or returning to class after lunch. Duration Recording. By using this site, you agree to its use of cookies. Latency is a temporal measure of elapsed time from some change in the environment to the occurrence of a specific behavior. The addition of latency recording to trial-based functional analysis is still just a theory being researched. Before creating your own latency recording form click here to view a completed example. I first started considering the use of latency in data collection while conducting trial-based FAs as a result of analysis of behavior that seemed to be clearly socially reinforced, but very unclear whether the most powerful contingency was related to attention, access to preferred, or escape/avoidance. Latency recording also can be used when a teacher is interested in the time it takes for a student to engage in an academic behavior after an instructional prompt is given. For instance, a teacher may be interested in how long it takes for a preschool student to join circle time or put his toys away once he is prompted. For instance, the amount of time from a teacher's prompt to begin working on an assignment to the behavior of the student picking up his pencil and starting to work on the assignment is a measure of latency. ²¿K”�ñ•Ù¶.Jöï>låTs§ë´ For instance, a teacher may be interested in how long it takes for a kindergartner to join circle time or put his toys away once he is prompted. In theTIME BEHAVIOR STARTEDsection, write the time the target behavior began. In this situation, you may want to teach a child how to ask for the preferred item using a new communication response. In addition to my own data, I've been able to find the following research on the topic: I hope to collect analysis and intervention data over several months to function as a case study. Latency of response during the functional analysis of elopement. Use the following link to access a data collection form that I created to use while conducting trial-based latency functional analysis: Contributions to are licensed under a Creative Commons Attribution Non-Commercial 3.0 License. The latency is 4 seconds in this scenario.

Trial-Based Functional Analysis is a variation on the traditional FA procedures whereby experimental control is demonstrated through paired sequences of control (Motivating Operation is absent) and test (Motivating Operation is present) conditions across potential functions. In theTIME OF DELIVERY OF ANTECEDANTsection, write the time of instruction, activity, etc. Trial-Based Latency Functional Analysis Record, Creative Commons Attribution Non-Commercial 3.0 License, A master's thesis by Elizabeth Dayton (2011) titled "An analysis of latency as the dependent variable in trial-based functional analyses." As with many of the data collection systems already discussed, professionals may choose to measure latency for increase or decrease. Latency recording is really useful when you are interested in the length of time between a specific cue, event, or verbal prompt and the occurrence of a behavior. Beyond that, I believe more research is needed to compare results of a traditional FA to results of a trial-based latency FA and determine whether or not adding a measure of latency increases the external validity over that produced by a trial-based FA without the use of latency. A wall clock, wristwatch, or stopwatches are all instruments that can be used to record latency. The teacher can then prompt the child to request the toy before he begins to cry and therefore prevent problem behavior. Advantages. To add your data, print this page, or go to File--> Make a Copy. Click here to print a blank latency recording form that can be used to collect your own data. For more information about this procedure, see the following research article: Bloom, S. E., Lambert, J. M., Dayton, E., & Samaha, A. L. (2013). If the average latency were 90 seconds, it may be appropriate to use a progressive interval reinforcement schedule with access to tangibles used as reinforcement. - When interested in the length of time between a specific cue, … I could identify antecedent conditions within each function under which problem behaviors would occur.

Sometimes videotaping or audiotape recording can capture what is happening in the classroom and can be reviewed at a later date. Click here for a printable version of a blank latency recording form. What are the advantages and disadvantages of latency recording? The University of Kansas prohibits discrimination on the basis of race, color, ethnicity, religion, sex, national origin, age, ancestry, disability, status as a veteran, sexual orientation, marital status, parental status, gender identity, gender expression, and genetic information in the university’s programs and activities. In the TARGET BEHAVIORsection, WRITE THE BEHAVIOR YOU ARE TRYING TO MODIFY. Interresponse time (IRT): Elapsed time between two successive responses. Consider the following data as an example: As the example data shows, the escape and tangible conditions are very similar if considering percentage of trials alone - 60% to 70%. Therefore, intervention effects following a trial-based latency FA should also be studied. This paper can be read. In this example data, the intervention choices are not only informed by the functional hypotheses, but also by the latency analysis for each function. Example: The teacher said touch dog, and 4 seconds later, the client touched the dog. Introducing a child to a new communication response can involve observing the length of time between a cue being presented and a problem behavior occurring. Latency recording can be used to prevent problem behavior by identifying the length of time between a triggering event (also called an antecedent) and the occurrence of problem behavior.
