Q

2 Behavior-Altering Effects of Antecedents

A
  1. Evoke: A response is more likely to occur in the moment
    - Evocative effect
  2. Abate: A response is less likely to occur in the moment

Availability of Reinforcement

A
  • An Sd (for Rx) is established due to its presence being correlated with a past availability of Rx
  • The Sd ‘signals’ that the reinforcer is available for a specific response

25
Q

Identify two ways to classify antecedent interventions based on the underlying mechanisms:

A
  • MO effects

- Discriminative effects

26
Q

Classifying Antecedent interventions (con..t)

A
  • Underlying mechanisms for their effects:
  • Contingency manipulations are designed to Evoke prosocial bx & abate prob bx & the Rx
  • Restricts ability: Makes it difficult or impossible to engage in the problem bx
27
Q

Role of Antecedents in Treatment

A
  • Antecedent manipulations are designed to evoke prosocial bx and abate problem bx
  • Effects are often transitory or momentary
  • Consequences determine long-term effects of an intervention
28
Q

Considerations for Antecedent Interventions

A
  • Use only as a component of a treatment plan
  • Combine with Rx procedures
  • Include extinction and/ or punishment procedures as part of the plan if needed
29
Q

Some Misconceptions About Antecedent Interventions

A
  • Shouldn’t situations that evoke prob bx just be avoided?
  • Isn’t lowering requirements at the start regarding bad bx?
  • Why increase requirements if prob bx is now low or has stopped?
30
Q

Generic Antecedent Interventions

A
  • Antecedent interventions that can have an effect on bx regardless of the function of the bx
  • The same intervention can be used across different functions
  • Occasionally cited as “default” interventions
31
Q

Which of the following is true of generic antecedent interventions?
(check all that apply)

A
  • Can have multiple uses
  • Can affect bx regardless of the maintaining contingency
  • Are also called “Default” interventions
  • Can abate problem bx
32
Q

Once the function of the behavior is determined, generic antecedent interventions cannot be used.

a. True
b. False

A

b. False

33
Q

Environmental Enrichment (EE)

A
  • Providing continuous, noncontingent access to social interaction, materials and/ or activities in settings of interest
  • AKA enriched env
34
Q

Mechanisms Underlying the Effects of EE

A
  • May function as abolishing operations (AOs) for:
  • Positive Rx (in the form of neg attention)
  • Neg Rx (in the form of escape)
  • Automatic positive/ neg Rx (in the form of sensory stimulation)
35
Q

Research Literature in EE

A
  • Most of the research has focused on reduction of stereotypic bx maintained by automatic +rx
  • e.g. from literature
  • Favell et al. (1982): Providing alternate sensory activities in the treatment of self-injury
36
Q

Considerations for EE

A
  • Use highly preferred stimuli
  • Vary &/ or rotate stimuli
  • Provide stimulation similar to maintaining consequences
  • Does Not consist of time-contingent delivery of preferred stimuli!
37
Q

Which of the following are considerations for environmental enrichment:
(check all that apply)

A
  • Use highly preferred items/ activities

- Very stimuli presented

38
Q

Explain the difference between environmental enrichment and time-contingent delivery:

A

In Env enrichment the items used & the attention provided are available continuously & can be accessed whenever the individual chooses to engage with a particular item or person. Time-contingent delivery is a schedule tht delivers preferred items or attention that possibly function as reinforcers on either a variable/ fixed time schedule

39
Q

Antecedent Exercise

A

*Involving individuals in a noncontingent systematic prob of effortful activities e.g. Aerobic, biking, dancing etc

40
Q

Mechanisms Underlaying the Effects of Antecedent Exercise

A
  • Likely to be MO effects, but not yet empirically verified

- Possibly pain reduction or “anxiety” reduction as an AO for neg Rx

41
Q

Mechanisms Underlaying the Effects of Antecedent Exercise (con…t)

A
  • Fatigue as a possible underlying mechanism has been rules out in several studies
  • Appropriate bx has often increased as a result of antecedent exercise
  • No decrease in activity level
42
Q

How can we determine that the effects of antecedent exercise are NOT due to fatigue?

A

We can observe an increase in alternative bx

43
Q

Relaxation Exercises
2 types

  1. Progressive relaxation
A
  1. Progressive relaxation:

Systematically tensing & releasing different pats of the body while engaging in deep breathing

44
Q

Relaxation Exercises
2 types

  1. Behavioral relaxation
A
  1. Behavioral relaxation: Using physical guidance, modeling, reinforcement & feedback to teach individuals to tense & release different parts of the body systematically
    - Used more often with naive learners
45
Q

Relaxation exercises involve deep breathing while tensing and releasing different parts of the body.

a. True
b. False

A

a. True

46
Q

Roland is a program manager at a group home. Every weekend he provides preferred activities for the residents to choose from throughout the day, including basketball, biking, video games, movies, music, and crafts. Which type of antecedent strategy is Roland using?

A

Environmental enrichment

47
Q

Terrence has a few students in his class who become agitated and engage in disruptive behaviors during his reading lesson. Because of this, each morning he has all students do deep breathing while tensing and relaxing different parts of their bodies. Which type of antecedent strategy is Terrence using?

A

-Relaxation exercises

48
Q

Cushion Antecedent Predictors

A

*Identifying the event that evokes the prob bx & modifying it in such a way as to abolish its effect & abate the prob bx

49
Q

Mechanisms Underlying the Effects of Cushioning Predictors

A
  • Likely to be MO effects:
  • AO for +Rx (in the form of attention)
  • AO for -Rx (in the form of escape)
  • Possible Sd effects
  • New Sd for +Rx developed
50
Q

Which of the following could be an underlying effect of cushioning predictors?

A
  • AO for positive Rx (attention)
  • AO for neg Rx (escape)
  • SD for +Rx
51
Q

Do not Mention “Bad” Bx

A

-do not talk in front of an individual as if they are not present when they are

52
Q

Mechanisms Underlying the Effects of Not Mentioning Behavior

A
  • Sd effects: -Mentoring = Sd for + rx
  • Not mentioning = Sdelta for + Rx
  • Possible MO effects -Mention in the presence of a new person (visitor) = EO for + Rx
53
Q

Identify the possible effects of mentioning problem behavior in presence of the behaver:

A
  • SD for positive Rx

- EO for positive Rx

54
Q

Medical Treatment

A
  • Interventions provided noncontingently for health related issue(s) that have an effect on prob bx
  • Treated by a physician, typically with medication

Q

Name some common medical issues you may encounter when working with individuals:

A

-Head aches, earache, toothaches, back aches, cuts, bruises, other injuries

56
Q

Noncontingent Restraints & Protective Equipment

A
  • The addition of equipment designed to restrict movement & prevent occurrences of prob bx
  • Highly restrictive & only used when absolutely necessary as a last resort
57
Q

Mechanisms Underlying the Effects of Physical Restraints

A
  • Abates problem bx by restricting the individual’s ability to engage in the prob bx altogether
  • May actually have an EO effect that is counter productive
58
Q

Treating self-injury with the use of protective equipment is a restrictive procedure that should only be used as a last resort.

a. False
b. True

A

a. True

59
Q

What could be the counterproductive effect of using restrictive protective equipment?

A

-It could function as an EO for the maintaining consequence

60
Q

Function-Based Antecedent Interventions

A
  • Antecedent interventions designed to correlate with the variables maintaining the bx
  • Interventions vary based on the function of the bx
61
Q

2 Broad, Function-Based Antecedent Strategies

A
