Tip-of-the-tongue moments may be benign

16.10.2013
Despite the common fear that those annoying tip-of-the-tongue moments are signals of age-related memory decline, the two phenomena appear to be independent, according to findings published in Psychological Science, a journal of the Association for Psychological Science.

Anecdotal evidence has suggested that tip-of-the-tongue experiences occur more frequently as people get older, but the relationship between these cognitive stumbles and actual memory problems remained unclear, according to psychological scientist and lead author Timothy Salthouse of the University of Virginia:

"We wondered whether these self-reports are valid and, if they are, do they truly indicate age-related failures of the type of memory used in the diagnosis of dementia?"

To find out, Salthouse and Arielle Mandell — an undergraduate researcher who was working on her senior thesis — were able to elicit tip-of-the-tongue moments in the laboratory by asking over 700 participants ranging in age from 18 to 99 to give the names of famous places, common nouns, or famous people based on brief descriptions or pictures.

Throughout the study, participants indicated which answers they knew, which they didn't, and which made them have a tip-of-the-tongue experience.

Several descriptions were particularly likely to induce a tip-of-the-tongue moment, such as: "What is the name of the building where one can view images of celestial bodies on the inner surface of a dome?" and "What is the name of the large waterfall in Zambia that is one of the Seven Wonders of the World?" Of the pictures of the politicians and celebrities, Joe Lieberman and Ben Stiller were most likely to induce a tip-of-the-tongue moment.

Overall, older participants experienced more of these frustrating moments than did their younger counterparts, confirming previous self-report data. But, after the researchers accounted for various factors including participants' general knowledge, they found no association between frequency of tip-of-the-tongue moments and participants' performance on the types of memory tests often used in the detection of dementia.

"Even though increased age is associated with lower levels of episodic memory and with more frequent tip-of-the-tongue experiences…the two phenomena seem to be largely independent of one another," write Salthouse and Mandell, indicating that these frustrating occurrences by themselves should not be considered a sign of impending dementia.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
