in the Blank:


 

1.     
___________ group receives treatment
in an experimental design.

 

2.     
___________ group does not receive
treatment in an experimental design.

 

3.     
A ______ _____ design has many
observations on a single case or a few subjects.

 

4.     
When separate groups of subjects
receive different levels of the independent variable, this is referred to as
_____________ design.

 

5.     
When all subjects receive all levels
of the independent variable, this is referred to as _________design.

 

6.     
When the researcher measures a
behavior that needs to be changed and then applies therapy and measures the
behavior again, this is referred to as _____________ design.

 

7.     
When the researcher measures a
behavior that needs to be changed, applies therapy and measures the behavior
again, and then removes the treatment and measures the behavior again, this is
referred to as ______________ design.

 

8.     
When the criterion outcome changes
over time this is referred to as ___ ____________ design.

 

9.     
When measuring several behaviors or
several people with baseline periods of varying lengths and an independent
variable occurs, this is referred to as a ____ _________ design.

 

10. 
When subjects are not randomly
assigned and not all variables are under the control of the presenter, this is
referred to as ______________ design.

Matching:

 

Read the following scenarios and
match each scenario with the correct type of experimental design.

 

 

1.     
______ Two classes of children are
studied regarding the effects of a new teaching method in science. One
group received the new method of instruction, while the other group uses the
standard, traditional method of instruction. Both classes are measures for
achievement before and after the teaching methods.

 

2.     
_____ Divide your subjects in
half.  One group receives one treatment of the independent variable
and the other group receives a different treatment of the independent variable.
Subjects were all told they were going to see a video of a therapist's session
after which they would rate the quality of the session. The groups differed in
that the subjects in one group were told that prior evaluations indicated that
the therapist was effective whereas subjects in the other group were told that
the evaluations indicated the therapist was not effective. These different
subjects were used for the two levels of the independent variable: subjects
were in either the "effective therapist" or the "ineffective
therapist" condition.

 

3.     
__________ All subjects perform at
all levels of the independent variable.  Subjects
diagnosed as having attention deficit disorder were each tested on a
concentration task after receiving medication. All subjects were tested four
times, once after receiving one of the four doses. Each subject was tested
under each of the four levels of the independent variable-dose of
medication.

 

4.     
________ A small group is measured
for the amount of anxiety they experience in math class (baseline). They
are taught a relaxation method and measured again to measure anxiety in math
class.

 

5.     
________ To study verbal
commands in canines, during week 1 the baseline is recorded for how many times
a dog chased a cat.  During week 2, dog was verbally scolded
(treatment) when the dog chased the cat, and the chasing behavior was
recorded.  During week 3, the chasing behavior was recorded without
the verbal scolding (treatment).
