Test Tuesday

Which of the following is not a component of informed consent?

1.  The ability to express his or her choices

2.  Voluntary Decision

3.  All potential risks and benefits of the planned procedure must be given

4.  Once the treatment has started, they are not able to refuse the treatment.

4.  Once the treatment has started, they are not able to refuse the treatment.

Due to the knowledge of treatment, the client has the right to refuse continued treatment at ANY time.  

Testing a Definition

So now that you have learned the characteristics of a good definition, how do you test to see if your definition is actually good?

Cooper, Heron, and Heward describe a few questions and answers to determine if you have a good definition.

1.  Can you count the number of occurrences?

-You should be able to answer "Yes"

2.  Will a stranger know what to look for based on the definition alone?

-You should be able to answer "Yes"

3.  Can you break the target behavior down to smaller,  more specific components?

-You should answer "No"

-The target behavior should already be broken down into the most specific components as possible

Test Tuesday

Which of the following is NOT a characteristic of a good operational definition?

1.  Objective

2.  Concise

3.  Socially valid

4.  Clear

5.  Complete

3.  Socially Valid

Test Tuesday

Given the following example, could you use a reversal design?

  During baseline a client cannot do a single math problem.  You are wanting to put in an intervention to increase the number of addition problems a client can do.  Could a reversal design be used in this situation?  Why or why not?

No.  A reversal design can NOT be used if the behavior is learned and irreversible. 

Need a recap on the reversal design.  Check out this link.

Multiple Baseline Design

Busy week this week, so today we get screenshots of the lesson!  Woo hoo! :)

Multiple baseline designs... My favorite! :)

Basic vs. Applied Research

Basic vs. Applied Research

Basic: does not focus on real-world application, and instead it just tries to describe the fundamentals of behavior.

Applied: focuses on application in the real world, but it still is based upon previous theory and assumptions that are made. 

Try it.

In the field of ABA, are we more concerned with applied or basic research?

Applied.

Frequency, Rate, Duration, Latency, and Interresponse Time

Fourth Edition Task List.

Section 1

A-01, A-02, A-03, A-04, A-05

Frequency:  This is just how many times that a behavior occurred.

Remember, FREQUENCY=COUNT

Example:  The client screamed 7 times during the hour observation period.

Rate:  Ratio of count per observation time.

Example:  The client engages in an average of 16 instances of screaming per hour. 

Duration:  A measure of the total time that the behavior occurs.

Example:  One instance of screaming lasted for 37 seconds.

Latency:  The elapsed time from the onset of a stimulus to the time that the response started.

Example:  The teacher said touch dog, and 4 seconds later, the client touched the dog.  The latency is 4 seconds in this scenario.

Interresponse time (IRT): Elapsed time between two successive responses.

Example:  13 seconds passed in between the two instances of screaming.

You try.

1.  If you are tracking a behavior that usually lasts anywhere from 5 seconds to 3 minutes on average, what method would you use to measure the behavior?

Duration.

2.  Why is calculating IRT important?

Calculating IRT is a good way to determine an appropriate interval length for DRO schedules.  It will let you know how long the client goes on average WITHOUT engaging in a certain problem behavior.
