Bobby has problem sitting still in class, and a behavior consultant works with a teacher
to develop a clinical program where she gives praise to Bobby for staying in his seat.
Bobby begins sitting more, and the teacher concludes to the behavior consultant that
her praise accounted for the change. The teacher is not aware of the fact that Bobby
has begun to take medication which makes him fatigued. In this case, the medicine is
playing the role of: - ANSWER an extraneous variable
between-groups design is a technique for organizing comparisons between control and
experimental (or treatment) conditions in which separate groups of participants are
exposed to control and experimental conditions so that the data reflect the pooled
performance of individual participants who have experienced only one of the conditions.
- ANSWER between-groups design
When behavioral variability is studied, the finest level of detail would be provided by: -
ANSWER analyzing the distribution of individual responses occurring during some
observation period
Which of the following methods represents all the approaches researchers and
practitioners utilize in studying behavioral variability, except: - ANSWER comparing
simultaneous but independent observations from two or more observers
An experiment that compares two different groups of subjects, one of which
experiences the independent variable and the other of which does not experience the
independent variable is a. design: - ANSWER between- groups
Although the control of extraneous variables to help control behavioral variability has its
advantages, it also presents some problems. All of the following are disadvantages
associated with this tactic, except: - ANSWER it is so difficult to do that the
investigator's time is often better spent on other issues
What is the problem for the study of behavior with using data from groups of subjects
,who are exposed to either the control or experimental condition alone? - ANSWER it
leads to data that mixed behavioral variability with intersubject variability
What does it mean to propose that variability in behavior is intrinsic? - ANSWER
variability is inherent in organisms and cannot be influenced by environmental factors
Variability is defined as the differences in responding between participants. - ANSWER
intersubject
What are the methodological consequences of assuming that behavioral variability is
extrinsic? - ANSWER it required the investigator to focus throughout the study or clinical
treatment on specific features of the relations between behavior of the individual and
the environment
The only source of variability whose impact is intentional is the _____. - ANSWER
independent variable
What three general functions does behavioral variability serve? ANSWER controls
experimental/ clinical decisions; forms basis for interpretations; stimulates investigator
What three kinds of biological influences on variability in behavior are there? ANSWER
cyclic physiological processes, developmental processes, and environmental effects on
body functions
What is the problem for the study of behavior with using data from groups of subjects
who are exposed to either the control or experimental condition alone? - ANSWER it
leads to data that mixes behavioral variability with intersubject variablity
The traditional assumption is that variability is ______ to the nature of organisms. -
ANSWER intrinsic
The phrase ______ refers to how researchers arrange comparisons between control and
experimental conditions so as to permit inferences about any effects independent
, variables may have on responding. - ANSWER experimental design
In the most general sense, ______ is the subject matter of all sciences. - ANSWER
variability
A(n) ______ is an effect of a participant's behavior resulting from exposure to a prior
condition. - ANSWER sequence effect
A pattern of responding that exhibits relatively little variation in its measured
dimensional quantities over some period of time is known as a _____. - ANSWER steady
state
A pattern of responding involving change from one steady state to a different steady
state is called a _____. - ANSWER transition state
If data show that responding is unstable under the baseline condition and/or under the
treatment condition, the researcher must assume that such fluctuations are due to: -
ANSWER extraneous variable
Transition and transitory states are defined by: - ANSWER the steady states immediately
before and after transition
The most widely used approach to establishing stability criteria depends on: - ANSWER
graphical analysis
______ criteria typically designate a small range of variation that will be allowed within
any fixed number of successive data points. - ANSWER statistical
A ______ is a repetitive pattern of local variability often involving sequences of rising and
falling trends (in either order). - ANSWER cycle
