3
B ACKGROUND Skinner & “ Functions of Behavior ” Research discovers 4 functions Practitioners could only guess Brian Iwata & et al. creates “Functional Analysis”
5
C LARIFICATIONS Function – Why a behavior is occurring (the “why”) Topography – The type of behavior (the “what”)
6
C LARIFICATIONS Different topographies can serve different functions
7
T HE R EAL F UNCTIONS Social Positive Social Negative Automatic Positive Automatic Negative
8
C LASSES Response Class – Different topographies of behavior that serve the same function Example: I hit to get your attention. I kick to get your attention. Hitting and Kicking for attention belong to the same response class.
9
C LASSES Stimulus Class – Two stimuli that share some common bond. Most frequently that they evoke the same behavior or function. Example: A stop sign and a red light are two different stimuli that evoke the same behavior.
10
C LASSES If you intervene on a specific topography Other topographies will most likely stay unchanged Unless they are in the same response class But there is no guarantee Behavioral Contrast
11
FBA VS. FA Functional Behavior Assessment (FBA) is any scientific assessment that gives support to the function of a behavior. Examples: Functional Analysis ABC Data Direct Observation Indirect Observation
12
FBA VS. FA Functional Analysis (FA) is just one type of FBA It’s the most accurate Has the most proven success rate (research based)

15
T HE FAST Please see handout
16
G ENERAL N OTES All of the conditions of a FA are overly strict and rigid. It’s important to control any extra variables so that the data you take is as accurate as possible.
17
C ONCEPTUAL Behavior increases when reinforced Behaviors have functions A given behavior (with a function) will be reinforced by that function (ie. Attention behavior will be reinforced by attention)
18
C ONCEPTUAL If we deliver an attention reinforcer for a problematic behavior and the behavior increases, then we know the behavior is attention maintained.
19
D EFINING B EHAVIOR Function Analysis work best of you focus on one specific topography. However, in practice, it becomes a problem to run multiple FA’s for different topographies. Therefore, we often observe multiple behaviors during one FA.
20
D EFINING B EHAVIOR You should have a clear definition of what counts as an instance of each target behavior.
21
C ONDITIONS 1) Alone/Ignore 2) Attention 3) Escape 4) Play (Baseline and Pairing) 5) Access (Optional) Repeat all conditions at least 3 times Can be either 10mins or 15mins long
22
A LONE /I GNORE Alone – Client is left alone in a bare room. Client is monitored via camera or through a one-way mirror. Ignore – Client is left in a room with an adult who does nothing and never attends to any behavior.
23
A TTENTION Attention – Client plays with a few toys. Professional ignores. If client emits a targeted behavior, professional gives attention in the form of mild chastising such as “Don’t do that”.
24
E SCAPE Escape – Client enters a bare room. Professional immediately begins to deliver SDs that have been observed in the client’s repertoire. Professional stops only when client engages in target behavior
25
P LAY Play – Client plays with a few toys. Professional ignores. Using a FT schedule (every 30 seconds) the professional will give specific praise to the student.
26
A CCESS (O PTIONAL ) Access – Client enters a bare room. Professional has a reinforcing item. Professional plays with item until the client engages in a target behavior. Then, the client is granted access to the item.
27
ORDERING The order of the conditions are important. Each condition creates a MO for the next condition.
28
E THICAL C ONCERNS Keep the client and the behavior separate!
29
E THICAL C ONCERNS These conditions are created to increase problematic behavior, so expect it. If you were put in these conditions, we would see similar behaviors.
30
E THICAL C ONCERNS Keep the safety of the client and yourself as a top priority.
31
D OWNFALLS Requires explicit informed consent Emotional process for parents, clients, and instructors
32
D OWNFALLS May temporally increase a problematic behavior Hard to explain why we want to increase problematic behavior Some behaviors are too severe
33
D OWNFALLS FA rely on contrived settings and may not elicit the behaviors seen in natural environments Time, effort, professional expertise, and ethical considerations
35
I NTERVENING Once you know the function, then you can develop an intervention plan that will be effective. Refer to handout (pg. 517 of white book) Remember that Antecedent Interventions are just as effective as Extinction or Punishment.
37
F INAL N OTES Notice how the handout lays out interventions for Attention, Access (tangible), and Escape
38
F INAL N OTES Until recently, the only research on Automatic Interventions has been around Response Interrupt and Re-Direction (RIRD)
39
F INAL N OTES In Spring of 2012, first research surfacing about other forms of intervention (see handout) – including research conducted at TCA
