Chapters 8 and 9 Flashcards
In dependent groups designs, the between participants variability is lower, which means that___.
there is less error variance**
there is less power
there is a larger effect
there is more generalizability
A within-participants design is also known as a(n)___.
independent groups design
between participants design
repeated measures design*****
mixed groups design
Craig is using a matched groups design to research the effect of a brief training class on math abilites. He matches partipants based on their height and eye color. What is the problem with Craig’s study?
The matching variables do not correlate with the dependent measure.***
The matching variables do not correlate with the independent measure.
The matching variables are error variables.
The matching variables are not powerful enough to detect significance.
Which is or are not problematic for within-subjects repeated-measures design?
A. Repeated tests of short-term memory B. Repeated measures of reading fluency C. Repeated measures using self-ratings of students’ problem behavior D. Repeated measures of blood tests*** E. None are problematic F. Only A and B
In a TEACCH study, 22 autistic spectrum students were matched on age and psychoeducational measures. Two conditions:TEACCH and control, pre-and post-tests on the psychoeducational measures, use a repeated measures 2x2 ANOVA, the independent variable is or are_____.
A. the psychoeducational measure
B. treatment group versus control group**
C. Pre and post-testing**
In a TEACCH study, what effect are Ozonoff & Cathcart (1998) interested in?
A. A significant pre-/ post-test effect that shows both groups have changed
B. A significant treatment by control group that shows there is a difference between groups
C. A significant interaction that shows across pre- post-test conditions that the treatment group improved and the control did not.***
D. All of these effects are of interest
In repeated measure ANOVA total vaiance is reduced because____.
the variance due to individuals is removed
Using repeated measures ANOVA,
increases power.
Juan’s teacher states that he does like to read. When Juan is asked to read outoud, he yells out, “I (expletive) hate reading” and is sent to the office. Next time his teacher asks him to read, he repeats what he said he time before. This is an example of :
Negative reinforcement***
Positive reinforcement
Negative punishment
Positive punishment
Each time a student breaks a classroom rule, the student loses 5 minutes of recess. Assuming the rule breaking behavior decreases:
This is negative reinforcement
This is positive reinforcement
This is negative punishment***
This is positive punishment
The biggest advantage of the ABAB design over the ABA design is ____.
A. The 2nd replication insures the causal nature of the manipulation.
B. That it rules out possible threats to internal validity.
C. There is no real advantage.
D. Both A and B.**
To determine whether a given treatment intervention works to reduce physical aggression and verbal abuse would require___.
A. A multiple baseline across settings
B. A multiple baseline across behaviors**
C. A multiple baseline across participants
D. Both A and B
E. Both B and C
