I study human memory. Though I study a broad range of issues related to human memory processes
and performance, my primary research interest is in people's ability to show memory when they
experience retrieval failure. For example, people sometimes fail to recall the information that they are
searching for in memory. When experiencing such memory failure, people often still have other infor-
mation available to them about the memory—information that can at times be used to make decisions
with remarkable accuracy. An example is the phenomenon recognition without identification and a
seemingly similar phenomenon, recognition without recall. I am interested in the various ways that
people can show memory when recall fails, and I am also interested in the neural mechanisms that
underlie memory that occurs when retrieval fails. In my lab, we use many methodological techniques
for addressing these questions, including behavioral paradigms, virtual reality technology, brain
electrophysiological techniques, and, in collaboration with other laboratories and facilities, functional
magnetic resonance imaging (or fMRI).
Familiarity-based Recognition. One example of a form of memory that can occur in the face of
retrieval failure is familiarity, which is the feeling of having experienced something before, without
being able to pinpoint exactly why the feeling is occurring. One branch of my research aims to study
familiarity as a basis for recognition and how it differs from other processes that enable recognition.
Features that Produce Recognition when Recall Fails. One branch of my research attempts
to identify what features of an item or situation can produce recognition when recall fails. For example,
when retrieval fails, do geometric shapes contribute to a sense of recognition with pictures and objects?
Do phonemes contribute to a sense of recognition with spoken words? Can rhythm contribute to a sense
of recognition with songs? Can more abstract features, such as semantic features, produce a sense of
recognition when retrieval fails?
Subjective Memory Experiences that Occur During Retrieval Failure. The ability to
recognize having had a prior experience with a situation when recall of the exact prior experience itself
fails is related to the subjective experience of sensing that something is in memory. Besides the feeling
of familiarity, an example of one such type of subjective experience is the déjà vu experience, which occurs when one has a feeling of having experienced something before, despite evidence to the contrary. Most commonly, déjà vu occurs with places—people experience a feeling of having been somewhere before, despite knowing that they have never been there. Déjà vu may result from a memory that fails to be retrieved, as is humorously illustrated in this commercial. One branch of my research aims to better understand déjà vu as a memory phenomenon, and virtual reality is one of the tools that we use in my lab to investigate this (click here for a video description).
Another example of a type of subjective memory experience that occurs during retrieval failure is the tip-of-the-tongue (TOT) phenomenon, whereby one feels that a word is in memory, but cannot currently access it. One branch of my research investigates this phenomenon and how it differs from other seemingly similar subjective memory experiences that occur during retrieval failure. Another branch is aimed at investigating how TOT states affect other cognitive judgments during the uncertainty of retrieval faiure.
Unconscious Recognition. Other ways that people can show memory when retrieval fails may
be unconscious. Recent evidence, from my lab and others, suggests that people may sometimes be
influenced by prior memories to choose certain items over others or to react in certain ways to
situations, yet be completely unaware that situations in memory are driving those decisions.
Another branch of my research aims to study this ability and how it differs from conscious forms
of memory that occur when retrieval fails.
