- When interested in the length of time between a specific cue, … Duration Recording. This type of data collection is appropriate for behaviors that follow a command or directive, or a distinct stimulus. As with many of the data collection systems already discussed, professionals may choose to measure latency for increase or decrease. Therefore, intervention effects following a trial-based latency FA should also be studied. However, consider the average latency for each condition across trials in which problem behavior occurred: The following latency data graphed across trials clearly demonstrates that the tangible condition consistently produced problem behavior quicker than the escape condition (seconds of latency are in reverse order on the vertical axis): In the end, an analysis is only as good as the success of the interventions it produces. 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. For more information about this procedure, see the following research article: Bloom, S. E., Lambert, J. M., Dayton, E., & Samaha, A. L. (2013). What are the advantages and disadvantages of latency recording? Before creating your own latency recording form click here to view a completed example. 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. Latency recording is a different type of duration recording that involves an observer measuring how long it takes for a behavior to begin after a specific verbal demand or event has occurred. 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." Make sure that you can identify a specific verbal instruction or an event that precedes the behavior of interest. LATENCY:The time it takes for a behavior to occur following the antecedent. 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.

Looking at percentage of trials alone, I thought, would not produce precise enough data to identify differences between the functions. Click here to view latency recording example. The latency is 4 seconds in this scenario. œ³Q�æÙ¢¿Yå�8›Ôaı Use the following link to access a data collection form that I created to use while conducting trial-based latency functional analysis: Contributions to https://sites.google.com/site/educationaba/ are licensed under a Creative Commons Attribution Non-Commercial 3.0 License. While frequency/event & rate recording can give you insights into the number of … 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. 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. 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. In theTIME OF DELIVERY OF ANTECEDANTsection, write the time of instruction, activity, etc. Latency recording requires some way of measuring time. 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. A wall clock, wristwatch, or stopwatches are all instruments that can be used to record latency. Interresponse time (IRT): Elapsed time between two successive responses. This short latency suggests antecedent/teaching strategies, such as an "Accepting No" protocol (see work by Carbone), in order to prevent problem behavior prior to the transition. Example: The teacher said touch dog, and 4 seconds later, the client touched the dog. We use data to know whether to change the program we are working on, when to switch or add new targets or when to "freshen up" a program to make greater progress. The addition of latency recording to trial-based functional analysis is still just a theory being researched. This information is used to find out exactly when to prompt a new communication skill that will result in the same outcome as the problem behavior. This information is used to find out exactly when to prompt a new communication skill that will result in the same outcome as the problem behavior. For instance, in the tangible condition, problem behaviors were experienced relatively consistently when transitioning from access to blocked access to preferred activities or items, with an average latency of 13 seconds. Data guides ABA programs. Latency of response during the functional analysis of elopement. This site uses cookies from Google to deliver its services and to analyze traffic. Click here for a printable version of a blank latency recording form. Latency is a temporal measure of elapsed time from some change in the environment to the occurrence of a specific behavior. The teacher can then prompt the child to request the toy before he begins to cry and therefore prevent problem behavior. 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).
