Multhaup, K.S., DeLeonardis, D.M., &
Johnson, M.K. Source memory and eyewitness suggestibility in older adults.
Journal of General Psychology,126 (1), 74-84.
Background:
-
Johnson’s source monitoring framework. Remember,
older adults have been found in numerous studies to be particularly bad
at source monitoring.
-
Loftus’ Misinformation Paradigm. The suggestibility
effect has been found with both young and old adults.
-
Lindsey and Johnson 91989) found the suggestibility
effect for those tested with the standard yes/no recognition test, yet
did not find it when using a source-monitoring test.
-
The argument is this: the source-monitoring test
reduces the suggestibility effect because it requires the individual to
use a more stringent decision criteria than does the yes/no familiarity
test.
-
Will a source-monitoring test reduce the suggestibility
effect in older adults as well as young adults as Lindsay and Johnson (1989)
found?
-
Multhaup (1995) found empirical support that source
monitoring tests will reduce source misattribution.
Predictions
-
Older adults would show a suggestibility effect when
tested with a yes/no recognition test, but would not when tested with the
source-monitoring test.
Method
-
Data from 128 elderly adults.
-
Broken up into 4 groups: control-source test; control-recognition
test; misled –source test; misled-recognition test.
-
Procedure:
-
View a slide for 20 seconds.
-
Read a narrative of the scene ( half were misleading)
-
Write a summary of slide scene
-
Memory test: either recognition or source test.
Results: Prediction is supported.
Meaning: The authors believe that the way
people are tested can and does affect how likely the suggestibility effect
is to occur. They remind that this does not mean that a source-monitoring
test will reduce all errors. But, the use of the test may cause an individual
to go beyond familiarity and cause an evaluation of the characteristics
of memory.
