Can a Concussion History Affect the Susceptibility to the Misinformation Effect?

Middlebury College, Middlebury, Vermont 05753

Concussions have been shown to have damaging effects to multiple functions of the brain,

including memory. One of the key components of memory is the ability to determine the

original source of a memory, a concept called source monitoring. The current study was

designed to explore how individuals with a history of concussions would compare with

individuals without a concussion history when their source monitoring ability was tested. The

researchers investigated the influence a concussion history would have on the susceptibility to

the effects of misinformation. Twenty individuals with a concussion history and twenty-two

individuals without a concussion history participated in the study. It was expected that

individuals without a concussion history would perform better on tests evaluating their ability to

correctly monitor the source of information. Statistical analysis revealed that both the concussed

and non-concussed group performed similarly in their ability to source monitor. The

contradictory results this study exhibits, when compared to previous research, suggests that

further exploration into this particular portion of memory may be useful when understanding

how concussions affect memory performance. The results of this study suggest that concussions

may not always produce negative long- term memory related cognitive effects.
