Continuous data measurement
Every instance of behavior is recorded
Frequency: number of times
Duration: how long
Latency: how long until response
IRT: time btw 2 consecutive responses
Percent: correct or independent
Discrete categorization
Discontinuous data measurement
Not every instance of behavior is recorded
Partial interval recording
Whole interval recording
Momentary time sampling
Types of preference assessments
Single stimulus
Paired stimuli
Multiple stimuli w/ replacement
Multiple stimuli w/o replacement
(Edibles and non-edibles should not be present in the same assessment)
Single stimulus preference assessment
Therapist presents a single stimulus to the learner and records the learner’s reaction (if engagement occurs and for how long)
Good for learners who have difficulty choosing
Paired stimuli preference assessment
Therapist presents 2 items at the same time and records the learner’s choice
For assessing items against each other
Multiple stimuli WITH replacement
Therapist presents learner with 3 or more items simultaneously, chosen item rotated back into array
Good for learners able to scan and select items ; avoids challenging behavior when items are removed
Multiple stimuli WITHOUT replacement
Therapist presents learner with 3 or more items simultaneously, chosen item is removed from array
Most effective way to determine hierarchy of preferred items
Antecedent
Events/actions that occur immediately before a behavior
Behavior
Observable, measurable action; something a person says or does in response to a stimulus
Consequence
Events or actions that occur just after a behavior
DTT (discrete trial teaching)
Instruction (antecedent)
Response (behavior)
Deliver reinforcement (consequence)
DTT: instruction
Mix of acquisition targets and already mastered targets
Use prompts as needed to teach correct response
DTT: response
The learner following the instruction
Re-present skills as needed; can be cold probe (independent) or errorless (prompted)
DTT: deliver reinforcement
Given after a set schedule of interval or responses (determined by learner’s skill level)
Conduct preference assessment to ensure most preferred items are used as reinforcement
NET (natural environment teaching)
Stay flexible and be prepared for moment to moment teaching
Follow the child’s lead (interest/motivation)
Activities can be short and repetitive
Contrive manding opportunities (narrate; generalize both mastered and target goals)
Forward chaining
Each step is taught in the order you would naturally complete them
Total-task chaining
All steps of the chain are targeted in unison, therapist prompts any skills not independent
Backward chaining
Behaviors linked beginning with last behavior in the sequence, reinforcement follows the final step
Backward chaining with leap aheads
Backward chain but not all steps are taught, any steps the learner is already able to complete independently are skipped
Components of shaping
Topography (form)
Frequency/rate
Latency
Duration
Magnitude
Shaping: topography (form)
Reinforcing small steps toward target sign, even if not correct shape
Shaping: frequency/rate
Increasing the target number of responses during a set amount of time
Shaping: latency
Decreasing the target amount of time from instruction to response
Shaping: duration
Increasing the amount of time a learner engages in a task
