Abstract: | Recent research has revealed that the presence of irrelevant visual information during retrieval of long-term memories diminishes
recollection of task-relevant visual details. Here, we explored the impact of irrelevant auditory information on remembering
task-relevant visual details by probing recall of the same previously viewed images while participants were in complete silence,
exposed to white noise, or exposed to ambient sounds recorded at a busy café. The presence of auditory distraction diminished
objective recollection of goal-relevant details, relative to the silence and white noise conditions. Critically, a comparison
with results from a previous study using visual distractors showed equivalent effects for auditory and visual distraction.
These findings suggest that disruption of recollection by external stimuli is a domain-general phenomenon produced by interference
between resource-limited, top-down mechanisms that guide the selection of mnemonic details and control processes that mediate
our interactions with external distractors. |
