Title: Exploring factors affecting magnitude of minimal interference benefits to long-term memory retention

Abstract: Periods of wakeful rest immediately preceding or following new learning can result in boosts to long-term memory retention. These benefits have been attributed to the minimization of interference which disrupts processes deemed crucial to successful remembering. Theoretical accounts diverge in the processes they believe are deeply rooted in forgetting (i.e. consolidation, retrieval) and the possible underlying mechanisms which result in their disruption (i.e. division of consolidative resources, temporal indistinctiveness at retrieval). Studies assessing the benefits of minimizing both interference encountered before (proactive interference) and after new learning (retroactive interference) attempt to establish which theory provides a more encompassing account of forgetting. However, in doing so, such studies have inadvertently highlighted factors which may affect the degree to which minimal interference benefits can be observed.

In this talk, I will explore three studies where such factors have been uncovered. We will see that the nature of the to-be-retained material may determine the ability for participants to overcome interference. We will also see that experimental designs may uniquely inflate certain minimal interference benefits, distorting our views on which theories appear more accountable. Ultimately, this talk will illustrate the volatile nature of observing minimal interference benefits in healthy adult populations and the critical implications this may have for investigating forgetting overall.
