TScore
A
standard score that sets the mean to fifty and standard deviation to ten. Used on a number of tests including the MMPI.
tTest
A group of statistics used to determine if a significance difference exists between
the means of two sets of data.
Tactile

Thematic Apperception Test
Temperament
A
persons typical way of responding to his or her
environment.
Temporal
Lobe
One
of the four lobes of the brain. Contains the
auditory cortex and therefore plays a role in
receptive language as well as memory and emotion.
TestRetest
Reliability
The correlation coefficient determined by comparing the scores of the same measuring device administered to the same people on two different
occasions.
Tetrachoric
Correlation
A correlational technique used to estimate the PearsonProduct correlation of two continuous variables that have been dichotomized (Example: age is continuous, but when it is split into two groups, such as over 40 and under 40, it becomes dichotomous).
Thalamus
Considered
the central switching station of the brain because
all of the body's senses (except the olfactory
senses) pass through this before being relayed to
the brain.
Thematic
Apperception Test (TAT)
A subjective
personality test where ambiguous pictures are
shown to a subject and they are asked to tell a
story related to them.
Theory
A
general idea about the relationship of two or more
variables.
Time
Series Design
A
research design where subjects are measured at
specific times before and after the treatment has been
administered in order to determine the long term
effects of the treatment
Trait
A
relatively
permanent internal characteristic (e.g., friendly,
outgoing)
Transference
Intense feelings directed toward the
therapist that many clients experience in the
process of therapy.
Trial
and Error Learning
Learning
that takes place through the application of
possible solutions to a problem.
True
Experiment
Research
design that utilizes the most control over
subjects and utilizes randomization
True
Score
the amount of the observed score that truly represents what you are intending to measure.
TwoWay
ANOVA
An Analysis of Variance used when there are two independent variables.
Type
A Personality
A theory used to
describe a person with a significant number of
traits focused on urgency, impatience, success,
and excessive competition.
Type
B Personality
A
theory used to describe person with a significant
number of traits focused on relaxation, lack of
urgency, and normal or reduced competition.
Type
I Error
The error that is committed when a true null hypothesis is rejected erroneously. The
probability of a Type I Error is abbreviated with the lowercase Greek letter alpha.
Type
II Error
The error that is committed when a
false null hypothesis is accepted erroneously. The
probability of a Type II Error is abbreviated with the uppercase Greek letter beta.
