Psy 417 Test 2

Question 1

3 primary reasons to assess agreement

Answer 1

1. For consistency
2. Minimizes biases
3. When agreement is high we know that the behavior is well defined

Question 2

Agreement vs. accuracy

Answer 2

Agreement- how well the data from separate observers corresponds

Accuracy- whether the observers data reflect the actual performance

Question 3

Multiple baseline contributions

Answer 3

• shows that the intervention changed the behavior without having to reverse the intervention. It also can be used to change multiple behaviors within one study

Question 4

Limitations to MBL

Answer 4

• Changing one behavior can influence change in another behavior.
• across setting, sometimes generalization from a behavior can occur
• across individuals- if individuals are allowed to watch then it can influence their behavior.
• prolonged baseline. Ethical

Question 5

Characteristics of changing criterion design

Answer 5

• one baseline phase
• when behavior meets criterion the next phase begins
• behavior improves in increments

Question 6

Major contributions of changing criterion

Answer 6

• used to increase non existing behaviors or lowing a behavior
• uses sub phases
• exercising example

Question 7

Limitations of CC

Answer 7

• if the behavior increases to quickly then this throws out the control
• the control of the experiment is based on whether the behavior meets the exact criterion.

Question 8

3 Guidelines for CC

Answer 8

1. Proceed gradually. Slower is better.
2. Each change needs to be large enough to show a noticeable change in behavior. More exact behavior is to criteria the better
3. Can be different sizes

Question 9

Rationale for multiple element

Answer 9

To show how clients perform differently during specific treatment conditions. (Teaching new sight words with different methods). Happens during same phase.

Question 10

Problems with multiple treatment

Answer 10

1. Omitting baseline- if the treatments don’t show any difference between each other then there is no way to know if they both worked or both didn’t work.
2. Type of interventions- has to fit around behaviors that can shift rapidly
3. Discriminability of the interventions: client needs to show that they see a difference between the interventions.
4. # of interventions- more interventions= more time
5. Multiple treatment interference- one treatment might be influenced by the others
