Motivation
  • Motivation is a major topic in psychology,
    especially applied psychology
  • A Google search of motivation produced 257
    million hits
  • 42 million for reinforcement
  • 7 million for stimulus control
  • 97,000 for discriminative stimulus (SD)
  • Behaviorists are rarely credited for any positive
    contribution to the study of motivation
  • In fact, discussions of behavioral approaches to
    motivation are usually misguided and pejorative
    (e.g., Dan Pinks TED presentation, Son-Rise vs.
    ABA)

3
A Behavioral Analysis of Motivation
  • An often missed element of Skinnerian psychology
    is that motivational control is an antecedent
    variable that is different from stimulus control
    and reinforcement (Skinner, 1938, 1953, 1957)
  • In Behavior of Organisms (Skinner, 1938) Skinner
    devoted two full chapters to motivation Chapter
    9 titled Drive and Chapter 10 titled Drive and
    Conditioning The Interaction of Two Variables
  • Science and Human Behavior (1953) had three
    chapters on motivation
  • Keller and Schoenfeld (1950) stated, A drive
    motivation is not a stimulusa drive has
    neither the status, nor the functions, nor the
    place in a reflex behavior that a stimulus
    hasit is not, in itself either eliciting,
    reinforcing, or discriminative (p. 276)
  • Keller and Schoenfeld suggested the term
    establishing operation be used for drive to
    distinguish it from the various types of stimuli

A Behavioral Analysis of Motivation
  • The study of motivation was not carried through
    to Applied Behavior Analysis in the 1960s, 70s,
    80s
  • Michael (1993) pointed out, In applied behavior
    analysis the concept of reinforcement seems to
    have taken over much of the subject matter that
    was once considered a part of the topic of
    motivation (p. 191)
  • Applied research on motivation is virtually
    nonexistent in the first 20 years of the Journal
    of Applied Behavior Analysis (JABA)
  • The Journal contained no entries for
    establishing operations or motivation in the
    first cumulative index (1968-1978)
  • During the next 10 years (1979-1988) there were
    still no entries for establishing operation.
    However, there were 5 entries for motivation,
    but they all involved motivation as a
    consequence, rather than as an antecedent
    variable

5
A Behavioral Analysis of Motivation
  • In addition, the experimental analysis of
    motivation is mostly absent from the 57 years of
    research in the Journal of the Experimental
    Analysis of Behavior (JEAB)
  • Michael (1993) noted that the basic notion MO
    plays only a small role in the approach currently
    identified as behavior analysis (p. 191)
  • But most importantly, the neglect of motivation
    leaves a gap in our understanding of operant
    functional relations (Michael, 1993, p. 191)

6
A Behavioral Analysis of Motivation
  • Skinner discussed the topic of motivation in
    every chapter of the book Verbal Behavior (1957),
    usually with his preferred terminology of
    deprivation, satiation, and aversive
    stimulation
  • Thirty points about motivation from Skinners
    book Verbal Behavior (Sundberg, 2013)

    usually with his preferred terminology of
    deprivation, satiation, and aversive
    stimulation
  • Thirty points about motivation from Skinners
    book Verbal Behavior (Sundberg, 2013)
  • Jack Michael and colleagues have published
    various refinements and extensions of Skinners
    analysis (Laraway, Snycerski, Michael, Poling,
    2003 Michael, 1982, 1988, 1993, 2000, 2004,
    2007)
  • Discriminative variables (SDs) are related to
    the differential availability of an effective
    form of reinforcement given a particular type of
    behavior motivative variables are related to the
    differential reinforcing effectiveness of
    environmental events (Michael, 1993 p. 193)
    (see also Michael, 1982)

9
Establishing Operations (Michael, 1993)
10
A Behavioral Analysis of Motivation
  • Motivation, in lay terms, is often talked about
    as wanting or needing things or events
  • For example, food deprivation
  • There are two behavioral effects involved
  • 1) the value of food becomes stronger
  • 2) food seeking behaviors are evoked
  • Or, being highly motivated to search the internet
    for Club Penguin
  • Two behavioral effects
  • 1) the value of a computer and a website address
    becomes stronger
  • 2) web searching behaviors are evoked
  • When values are low (satiation, or website found)
    behavior is abated

11
A Behavioral Analysis of MotivationMichaels
(2007) Framework
  • An increase in the value of food or a website url
    is termed an establishing operation (EO) while a
    decrease in the value is termed an abolishing
    operation (AO)
  • The term motivating operations (MOs) is an
    omnibus term for these value changing effects
    (EOs and AOs)
  • The value changes then in turn affect behavior
    (value-altering effect)
  • EOs evoke specific behaviors, AOs abate specific
    behaviors (behavior-altering effect)
  • Michaels definition of motivation any
    environmental variable that (a) alters the
    effectiveness of some stimulus, object, or event
    as a reinforcer and (b) alters the current
    frequency of all behavior that has been
    reinforced by that stimulus, object, or event
    (2007, p. 375)

Michaels Chapter on Motivating Operations in
Cooper et al. (2007)
13
A Behavioral Analysis of MotivationSummary
  • MOs constitute a separate basic principle of
    behavior
  • MOs are antecedent events, not consequences
  • All types of MOs are separate from stimulus
    control
  • MOs and SDs frequently occur together as forms of
    multiple control

14
The Basic Principles of Operant Behavior
  • Stimulus Control (SD) Response
    Reinforcement
  • Motivating Operation (MO) Punishment
  • Extinction
  • Conditioned reinforcement
    Conditioned punishment
  • Intermittent reinforcement

15
A Behavioral Analysis of MotivationSummary
  • All types of MOs are separate from, but related
    to, reinforcement
  • MOs effects are separate from schedules of
    reinforcement effects
  • Aversive stimulation can function as MOs
  • Aversive stimulation as an antecedent (an MO) is
    different from aversive stimulation as a
    consequence (punishment)
  • Escape and avoidance are MO effects, not SD
    effects
  • MOs may involve unconditioned or conditioned
    variables
  • A single MO can control large repertoires (e.g.,
    revenge)
  • MOs are typically private events
  • Collateral behavior can help to determine MO
    level (e.g., reaching)
  • Much of what is termed emotion involves MOs
    (SHB, chap. 10)

16
The Application of Establishing Operations
(Sundberg, 1993)
17
Application 1 MOs as Antecedents Provide an
Additional Tool for Assessment and Intervention
  • MOs play a significant role in multiple facets of
    the assessment and intervention process for
    children with autism
  • MOs can be manipulated as an independent variable
    (like reinforcement, SDs, schedules, etc.)
  • MOs in relation to language acquisition and
    academics (e.g., math)
  • MOs in relation to social behavior (e.g., peer
    interaction)
  • MOs in relation to problem behaviors (e.g.,
    aggression)
  • MOs in relation to learning barriers (e.g.,
    scrolling in manding)
  • MOs in relation to group skills (e.g., aversive
    events evoke escape)
  • MOs in relation to self-help skills (e.g., clean
    hands)
  • MOs in relation to nonverbal skills (e.g., fine
    motor)

18
Application 2 MOs as the Primary Antecedents
for Manding
  • All mands are controlled by motivating operations
    (MOs)
  • There must be an MO at strength to conduct mand
    training
  • MOs vary in strength across time, and the effects
    may be temporary
  • MOs must be either captured or created to conduct
    mand training
  • MOs may have an instant or gradual onset or
    offset
  • Instructors must be able to reduce existing
    negative behavior controlled by MOs
  • Instructors must be able to identify the presence
    and strength of MOs, and capitalize upon them for
    teaching opportunities
  • Instructors must know how to bring verbal
    behavior under the control of MOs

19
Application 3 Demand can Weaken a Motivating
Operation (MO)
  • There is a direct relation between the value (MO)
    of a reinforcer and how much work (response
    effort) is required to obtain that reinforcement
    (e.g., Alling Poling, 1994)
  • Too much of a work demand can reduce the strength
    of an MO
  • An iPad may be reinforcing if it is
    noncontingent, but less so if work is required
  • Dont be dependent on rfmt. surveys and
    preference assessments
  • Sitting, attending, and responding to task
    demands can be quite a high response requirement
    for some children (video Julian)

  • Sitting, attending, and responding to task
    demands can be quite a high response requirement
    for some children (video Julian)
  • Staff must anticipate and account for MO value
    changes
  • Many intervention strategies are available, for
    example
  • identify the conditions under which a change is
    observed
  • start with a low response requirement and high MO
    value
  • gradually increase the response requirement

21
Application 4 Aversive MOs as Antecedents
  • Learned aversive motivators are ubiquitous in
    everyday behavior
  • We all encounter bad/undesirable things and
    events we dont want
  • Aversive stimuli increase the value of their
    termination and evoke behaviors that terminate
    the stimuli through negative reinforcement
  • Michael terms these conditioned motivating
    operations reflexive (CMO-R)

Increased value of termination
Evokes escape- avoidance behavior
Remove aversive negative rfmt.
CMO-R

Tantrum, push materials to floor

22
Application 4 Aversive MOsas Antecedents
  • Adults, tasks, settings, demand, tone of voice,
    body movements, contexts, materials, problems,
    etc. can function as aversive MOs
  • Possible CEO-R presence in DTT
  • Teaching children how to handle or remove
    aversives appropriately
  • Do not let the negative behavior delay or remove
    the aversive stimulus
  • Do a curriculum analysis, mitigate the aversive,
    decrease the response effort
  • Increase the reinforcement for responding when
    aversive MO is present
  • Do not offer reinforcers following negative
    behaviors (remember what youre working for)

23
Application 4 Aversive MOs as Antecedents
24
Application 5 MOs can Compete With Each Other,
and Block or Distort Stimulus Control
  • One MO can be more powerful than another MO
    (e.g., a stim. toy vs. social approval)
  • MOs are sometimes so powerful they overpower SDs
    (blocking) (e.g., iPad, string, He does not
    listen to me)
  • MOs can distort SDs (e.g., lying, exaggeration)
    (Brian Williams)
  • Be aware of a students strong MOs and possible
    effects on him
  • Be aware that table-top teaching may not
    adequately reflect an environment where there are
    competing MOs
  • Systematically require SD responding when the
    competing EO is present (may be easiest to start
    with a relatively weak EO)
  • Be aware that NET may inadvertently cater to
    powerful MOs
  • Control MOs, dont let them control you

25
Application 6 Using MOs to help Establish Other
Skills (Multiple control)
  • We often learn new skills because of some MO to
    do so (e.g., new Lego set, new game, navigation
    system)
  • Incorporating MOs along with SDs and
    reinforcement can enhance skill acquisition
    (e.g., Carroll Hesse, 1987)
  • Learning to tact things a student is interested
    in
  • Learning intraverbals about favorite topics
  • Reading and writing about favorite topics
  • MOs can help establish nonverbal skills as well
    (e.g., fine and gross motor skills, grooming
    skills)

26
Application 7 Breaking Free from MO Control by
Using Generalized Conditioned Reinforcement
  • MO control can get to be too strong (e.g., iPad,
    dinosaurs, OCD)
  • generalized reinforcement destroys the
    possibility of control via specific
    deprivations. (Skinner, 1957, p. 212)
  • we weaken the relation to any specific
    deprivation or aversive stimulation and set up a
    unique relation to a discriminative stimulus. We
    do this by reinforcing the response as
    consistently as possible in the presence of one
    stimulus with many different reinforcers or with
    a generalized reinforcer. The resulting control
    is through the stimulus. (Skinner, 1957, p. 84)
  • Moving a mand to a tact or intraverbal through
    generalized reinforcement
  • Also, use pictures, satiation, and competing MOs,
    low demand

27
Application 8 Developing or Repairing Social
Skills
  • Weak EOs for social interaction are a problem for
    many with autism (e.g., may not attend to peers
    or their interests)
  • Negative behaviors may occur as barriers (e.g.,
    excessive manding, irrelevant IVs, verbal
    perseveration, weak listener repertoires)
  • There are many complicated behavioral repertoires
    that fall under the rubric of social behavior
  • Create MOs for verbal behavior with peers (e.g.,
    manding to peers)
  • Create MOs for nonverbal behavior with peers
    (e.g., games, activities)
  • Identify and amelioriate problematic CEO-Rs
    (e.g., avoiding peers)

28
Application 9 Developing or Repairing
Self-help Skills
  • Distinction between structural and functional
    self-help skills
  • Why do you brush your teeth, shower, or carefully
    select clothing?
  • The MOs that control your behaviors may have
    little effect on teenagers with autism
  • MOs related to avoiding the social punishment of
    having body odor or bad breath
  • MOs related to positive social reinforcement for
    a stylish look
  • Creating MOs and assuring that target behaviors
    are under MO control rather than solely under the
    control of SDs
  • Set up a play-date, meeting, event, contest,
    game, etc.
  • Establish and link MOs to a self-checklist
  • Use MOs to identify potential vocational
    directions
  • Use MOs to teach community living skills

29
Application 10 Asking Questions- Mands for
Information
  • Asking a question is usually a mand, thus the
    source of control must be an MO
  • The MO for information (verbal or nonverbal) must
    be the primary source of control (MO?ask
    AO?dont ask)
  • The consequence must be the information, not
    edibles, tokens, etc.
  • Questions are not developmentally appropriate
    until approximately a two-year linguistic level
  • Must create or capture an EO (e.g., missing toy)
  • Use prompts (e.g., echoic, textual), fade prompts
    (e.g., Wheres Elmo)
  • Reinforcement for asking questions must be the
    information that corresponds with the EO
    (location of the toy)

30
Conclusions
  • Motivation is an extremely important aspect of
    human behavior
  • Behavior analysis has a powerful formulation of
    motivation that has not been developed much in
    ABA
  • There is a tremendous need for empirical research
    on the application of the MO to work with
    children with autism
  • The applications to the treatment of children
    with autism are abundant, but it is up to us to
    develop them
