WASHINGTON: Ever wonder how you remember a personâ€™s name but just canâ€™t recall where you met them? Well thatâ€™s the question scientists at The University of Western Ontario have found the answer to.
According to the researchers, the sometimes eerie feeling experience when recognising someone, yet failing to remember how or why relies on a distinct brain mechanism and does not simply reflect a weak form of memory.
â€œRecognition based on familiarity can be contrasted with recognition when we spontaneously conjure up details about the episode in which we encountered the person before, such as where we met the person or when it happened,â€ said psychology professor Stefan Kohler.
The research is based on Western psychology graduate student Ben Bowlesâ€™ Masterâ€™s thesis.
The study is important as it has implications for understanding memory deficits in neurology, including in Alzheimerâ€™s disease.
Bowels and Kohler also report that a rare form of brain surgery that can be highly effective for treatment of epilepsy can selectively impair the ability to assess familiarity.
â€œIt is counterintuitive but makes a lot of sense from a theoretical perspective that familiarity can be affected, while the ability to recollect episodic detail is completely spared,â€ adds Kohler.
The study was conducted in collaboration with researchers at the London Health Sciences Centre, McGill University, and at the University of California.
Supported by a grant from the Canadian Institutes of Health Research (CIHR) to Dr Kohler, the research was recently published in Proceedings of the National Academy of Sciences USA .
