Threats to internal validity include: -
answer Testing, maturation,
procedural infidelity
Match the definition. 2A. Events that
occur during the experiment but that
are not related to planned
procedural changes that may
influence the outcome - answer
History
2B. Changes in behavior due to the
passage of time - answer Maturation
,2C. Occurs when participants need to
respond to the same test repeatedly
during a baseline or probe condition,
which influences responding -
answer Testing
Threats related to the measurement
system, and are of concern because
of repeated measurement by human
observers who may make errors -
answer Data instability
Inconsistent implementation of the
experimental condition - answer
Procedural infidelity
The loss of participants during a
study, which limits the generality of
findings - answer Attrition
, Occurs when a participant's behavior
is influenced by more than one
planned intervention during the
course of a study - answer Multiple
treatment interference
A type of data instability that refers
to a repeated and predictable
pattern in the data series over time -
answer Cyclical variability
Carryover Effects - answer -Refers
for an effect of being tested in one
state on participants' behavior in
later situations
- May occur in a within-subject trial
when the effect of a particular level
of the self-independent variable
persists even after the treatment
finishes
