Functional Analysis test 2

Iwata et al., 1994 (Original FA Procedures)

Chapman et al., 1993 (Concurrent FA Procedures)

Red - Medical Staff Attention

Orange - Mother Attention

Blue - Escape from work activities

Yellow - Control no consequence

Smith & Churchill, 2002 (How to validate a precursor)

If both the Precursor & Target Behavior Function Analysis matched

If contengencies placed on the precursors caused a reduction in the SIB

Fahmie & Iwata, 2011 (Main Precursor Categories)

Vocalizations (Say something)

Small Movements (Reaching for a stimulus)

Loco Motions (Running)

Posture (Holding Knees)

Bloom et al., 2011 (Describe Trial-Based Functional Analysis TBFA)

Control for 2 minutes

(AO – Continuous Access)

To

TEST </=2 min

(EO + Contingent Access)

Then

Control for 2 minutes

(AO – Continuous Access)

These three trials occurred for each condition

Sessions were terminated when problem behavior occurred, except during the ignore condition

Thomason-Sassi et al., 2011 (Describe Latency FA)

The shorter the latency the stronger the response

What response has a shorter latency

The response that has the shortest latency is most likely the function of behavior. This is the value at the bottom of the latency graph.

Latency scale

Up to 300-600 seconds on Y axis

RPM on X Axis

With legend

Key part should be lower in the latency graph (the condition at the bottom of the graph and closest to 0 seconds is the function of behavior since it occurs the quickest after the session begins.
