Probing Skills
Define
A test to determine how a child responds to something

Probing Skills
Define
Probing skills used in…
Assessments Determine prompt level for programs Determine appropriate behavioral interventions for BSP Test for generalization Test for maintenance
Rationale for probing
Should be used to answer…
- Does the skill currently exist already?
- Least amount of prompting required for the response to occur?
- What effect does a particular intervention have on a behavior?
Best Practices
- closest naturalistic as possible
- probes should not be close together
- any reinforcement or ec should be natural and not contrived

Best Practices (type of probing)
Probing Under Extinction
AKA “Cold probe”
- Specifically do not provide reinforcement or ec
- Most common probing for assessment
- Reinforcement can be provided on a VI or FI schedule for general participation

Probing Outside of Assessment
Prior to introduction of instruction
- Test for concept formation/generativity (ability to generalize across response class)
- Determine current performance to select prompts
- For maintenance

Probing Outside of Assessment
Probes Prior to Instruction
- Identify where current skill set is
- Least to most prompting
- Look for concept formation/generativity
- Generalize across response class

Probes Prior to Instruction
Probing Throughout Instruction
- Kid makes progress on errorless targets that prompt steps may be skipped
- Information may be gleaned from probing
- Makes instruction more effective by only teaching at levels required

Probing Throughout Instruction
First Trial Probes
- During acquisition programs
- RBTs only collect data on the first trial run
- Reinforcement and ec are provided according to the prescribed program

First Trial Probes
Pros of First Trial Probes
- Lower response effort for RBTs
- Faster mastery
- Gives info on skill retention between days
Cons of First Trial Probes
- Less precise measurement
- First instance could get it, rest of them miss, so really they don’t have it mastered, but the data says 100%
- Lower maintenance
- Obscures other important trends
Maintenance Probes
- Skills that do not get reinforcement regularly are at risk for being extinguished
- Lower-level skills that are required for a higher-level skills are less likely to be extinguished
- Ensuring that skills are maintained is integral to ensuring that ABA is valid and useful for patient and their family

Maintenance Probes
Assessment Probes
Multiple probe design
- Variation of multiple baseline design
- Measuring intermittent data during baseline
- Saves time and effort to record
- Data should be collected at the right times to establish trends and patterns in the data
