14-Task Analysis Flashcards
A breakdown of a complex task into a particular sequence of small individual components steps, i.e., divides a long behavior chain into smaller, more teachable steps
The number of steps required per task break down maybe increase or decrease depending upon a learned skill level. E.g., if a learner is not mastering a component of the task analysis, then that component may be broken down into additional subcomponents
Development often involves completing the task ones self, or observing or consulting with individuals who demonstrate a high skill level of performance.
Task analysis
Example of handwashing may seem simple, but if they learned is struggling with it, then this could break it down into the following steps
- Turn on the faucet and adjust the temperature
- . Wet hands
Etc
Task analysis
Often used to inform a behavior analyst which responses will be targeted during a CHAINING procedure that is used to teach the skill
Task analysis
Methods that can be used to link a specific sequence of stimuli and responses that compose a complex performance or skill
Can be used to teach a completely new performance, or to add responses to an already existing repertoire
Chaining
Forward
Total task
Backward
Three common types of chaining procedures
Responses are taught often with prompting and fading, one at a time, in the same order they naturally occur
Imitation: Natural reinforcer may be too far removed
Forward chaining
All steps are performed or trained often with prompting and feeding in each learning trial, in the same order as they naturally occur
Total task chaining
Like with forward chaining, the steps are taught in the same order as they naturally occur
Unlike Forward chaining, every single trial results in all of the steps being performed with or without assistance, and the natural reinforcer is typically delivered after completion of the last step
Total task chaining
Responses are taught, Often with prompting and feeding, one at a time, but beginning with the stuff that would naturally occur last in the chain
Reinforcement is delivered after the last step that naturally occurs in the chain has been completed, provided that all of the steps following the steps being trained have been independently performed to criterion
Can use this when the natural reward is too far removed from most of the training and forward chaining. Or when..
The skill might be too difficult for total task training for the particular learner.
Backward chaining
If a learner is struggling with a particular step from a task analysis, despite prompting and fading, then the teacher should most likely consider which of the following?
A. Increasing the total number of steps for the task
B. Decreasing the total number of steps for the task
C. Fade prompts more quickly
A
This is a tricky question! We are only increasing the number of steps so we can break down the task even further into additional Saba components i.e., easier to learn many steps
ASR: if the behavior analyst props and feeds all the way through the entire task, from step one to the last step, every trial, then which type of training is used
Forward
Backward
Total task
Total task: going through the entire task every trial indicates total task training
