Latency is a temporal measure of elapsed time from some change in the environment to the occurrence of a specific behavior.

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. 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. As with many of the data collection systems already discussed, professionals may choose to measure latency for increase or decrease. 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. In theTIME BEHAVIOR STARTEDsection, write the time the target behavior began. Interresponse time (IRT): Elapsed time between two successive responses. 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. Looking at percentage of trials alone, I thought, would not produce precise enough data to identify differences between the functions. The following persons have been designated to handle inquiries regarding the nondiscrimination policies and are the Title IX coordinators for their respective campuses: Executive Director of the Office of Institutional Opportunity & Access, IOA@ku.edu, 1246 West Campus Road, Room 153A, Lawrence, KS 66045, 785-864-6414, 711 TTY (for the Lawrence, Edwards, Parsons, Yoder, and Topeka campuses); Director, Equal Opportunity Office, Mail Stop 7004, 4330 Shawnee Mission Parkway, Fairway, KS 66205, 913-588-8011, 711 TTY (for the Wichita, Salina, and Kansas City, Kansas, medical center campuses). 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 OF DELIVERY OF ANTECEDANTsection, write the time of instruction, activity, etc. Make sure that you can identify a specific verbal instruction or an event that precedes the behavior of interest. To add your data, print this page, or go to File--> Make a Copy. Sometimes children engage in problem behavior to obtain a preferred item. The addition of latency recording to trial-based functional analysis is still just a theory being researched. This type of data collection is appropriate for behaviors that follow a command or directive, or a distinct stimulus.

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. 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. Duration Recording. 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. Neidert, P. L., Iwata, B. In the TARGET BEHAVIORsection, WRITE THE BEHAVIOR YOU ARE TRYING TO MODIFY. Use latency recording when a behavior has a clear beginning so that you can tell exactly when the behavior starts. 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 of response during the functional analysis of elopement. 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. If a child cries whenever a toy is in view but out of reach, it can be useful to find out the latency before crying. 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. 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.

Sometimes videotaping or audiotape recording can capture what is happening in the classroom and can be reviewed at a later date. A., Dempsey, C. M., & Thomason-Sassi, J. L. (2013). In this situation, you may want to teach a child how to ask for the preferred item using a new communication response. Teacher-­conducted trial-­based functional analyses as the basis for intervention. 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. The latency is 4 seconds in this scenario. 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. LATENCY:The time it takes for a behavior to occur following the antecedent. 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. Example: The teacher said touch dog, and 4 seconds later, the client touched the dog. 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." 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. Latency recording requires some way of measuring time. Advantages. 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. This File is VIEW ONLY. Finally, as stated above, analysis is only as good as the success of interventions it produces. Data guides ABA programs. Latency measures the time between the discriminative stimuli (SD) and the response. 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. A wall clock, wristwatch, or stopwatches are all instruments that can be used to record latency. I could identify antecedent conditions within each function under which problem behaviors would occur.

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. 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. 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). œ³Q�æÙ¢¿Yå�8›Ôaı 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. While frequency/event & rate recording can give you insights into the number of … Response latency: Latency refers to the amount of time after a specific stimulus has been given before the target behavior occurs.
