Psychological assessment refers to - ✔✔systematic gathering and evaluation of information
|| || || || || || || || || || ||
pertaining to an individual with suspected abnormal behaviour.
|| || || || || || ||
Psychological testing - ✔✔provides data that are placed within the context of history,
|| || || || || || || || || || || || ||
referral information, behavioral observations, and life of an individual.
|| || || || || || || ||
In an experiment, the __________ group is exposed to a variable which is manipulated,
|| || || || || || || || || || || || || ||
called the __________ variable. - ✔✔experimental; independent
|| || || || || ||
When differences in some dependent variable are found to occur as a function of
|| || || || || || || || || || || || || ||
manipulation of the independent variable, a(n) __________ is obtained. - ✔✔experimental
|| || || || || || || || || || ||
effect
Claire completes a psychological test of personality type twice, the second time 4 weeks
|| || || || || || || || || || || || || ||
after the first. The correlation between her two test scores was very low. Based on this
|| || || || || || || || || || || || || || || ||
information, the test can be said to exhibit - ✔✔low test-retest reliability.
|| || || || || || || || || || ||
Several clinical psychologists are conducting a study about the treatment of Generalized
|| || || || || || || || || || || ||
Anxiety Disorder. Before receiving the various treatments, the participants were assessed on
|| || || || || || || || || || ||
a number of psychological measures. According to the terminology in the text, these
|| || || || || || || || || || || || || ||
measures would be referred to as - ✔✔pretests.|| || || || || || ||
According to the text, which of the following is NOT true of alternate form reliability
|| || || || || || || || || || || || || || ||
estimates? - ✔✔A low correlation between the two forms demonstrates good alternate-form
|| || || || || || || || || || || ||
reliability.

Which of the following is a measure of internal consistency? - ✔✔Coefficient alpha
|| || || || || || || || || || || ||
In the TADS experiment, described in the text, the researchers used a double-blind
|| || || || || || || || || || || || ||
procedure, meaning that - ✔✔neither the participants nor the experimenters knew who
|| || || || || || || || || || || ||
was getting medication and who was getting a placebo.
|| || || || || || || ||
A particular questionnaire is intended to measure musical enjoyment. One of the questions
|| || || || || || || || || || || || ||
is "Do you enjoy listening to music?" This item can be said to have - ✔✔face validity.
|| || || || || || || || || || || || || || || ||
When evaluating an experiment, one needs to consider its external validity, or - ✔✔the
|| || || || || || || || || || || || || ||
degree to which the results of the study can be generalized to other individuals in different
|| || || || || || || || || || || || || || || ||
settings.

|| || || || || || || || || || || || || || || || ||
_____________. - ✔✔split-half reliability; coefficient alpha || || || || ||
A confound occurs when - ✔✔two or more independent variables exert their influence on a
|| || || || || || || || || || || || || || ||
dependent variable at the same time. || || || || ||
It has been said that without _______, you cannot have ____________. - ✔✔reliability;
|| || || || || || || || || || || || ||
validity

|| || || || || || || || || || || || || || || ||
specific theoretical framework. || ||
Which of the following is NOT true of correlational studies? - ✔✔They generally do not
|| || || || || || || || || || || || || || ||
require a large number of participants. || || || || ||
Which of the following is NOT true of the actuarial approach? - ✔✔Those who endorse it
|| || || || || || || || || || || || || || || ||
argue that there is no substitute for the clinician's experience and personal judgment in
|| || || || || || || || || || || || || ||
coming to decisions. || ||
If two variables are found not to be related to one another, then the correlation coefficient of
|| || || || || || || || || || || || || || || ||
the relationship between these two variables should be close to - ✔✔zero.
|| || || || || || || || || || || ||
Which of the following are problems with the actuarial approach? - ✔✔Many of the
|| || || || || || || || || || || || || ||

|| || || || || || || || || || || || ||
equal to - ✔✔+0.30 or -0.30.
