SourceMemory_Age_verbal responses.xlsx

This study looked at eye movements in relation to source memory in older adults. Participants
first studied images of common objects appearing in different quadrants of a
screen. After a delay, they were shown
cues one at a time presented in all four quadrants. Participants stated whether
or not the cue had been seen before and in which location. Participants also
rated level of confidence in their responses. In trials where participants
either claimed they have not seen a previously presented cue or placed it in an
incorrect location, they looked significantly more at the correct quadrant. The
proportion of time looking at the correct quadrants during incorrect responses was
not related to confidence ratings. These results suggest that eye gaze during
the memory task does not reflect memory retrieval below the threshold of verbal
report. They instead point to an implicit form of source memory in humans that
is accessible to eye movements but not to verbal responses.
The data consist of: E-Prime output participant files recording the behavioral and eye tracking data, and a file with the participants location responses which were manually recorded.
