When Less Attention Improves Behavior

21.01.2009
A new study conducted at the Centre for Studies and Research in Cognitive Neuroscience of the University of Bologna, and published by Elsevier in the February 2009 issue of Cortex (http://www.elsevier.com/locate/cortex) shows that, in confabulating patients, memory accuracy improves when attentional resources are reduced.

Most cognitive processes supporting adaptive behavior need attentional resources for their operation. Consider memory. If memory was a car, attention would be its fuel: New information is not stored into memory if not attended to, and distraction often leads to misremembering past events.

What if the car’s brakes are broken? Will adding fuel still be a good thing? Confabulation is a devastating memory disorder consisting in the uncontrolled production of “false memories”. Patients often act upon their false memories, with dramatic consequences. The research published in Cortex shows that if memory in confabulation is like a car with broken brakes, then it is best not to add fuel.

The study involved patients with lesions in the prefrontal lobe, including patients with and without confabulation, and healthy individuals. In two experiments, participants retrieved their memories either with full attention or divided attention (i.e., while doing another task). Non-confabulating patients and healthy individuals performed better when their full attention was devoted to the memory task. Not so for confabulating patients: Under full attention, confabulating patients exhibited high false-memory levels, which were strongly reduced when their attention was divided between two tasks.

The results of this study are important both theoretically and practically. First, they indicate that lack of attention during memory retrieval is not the reason for confabulation. Rather, confabulating patients might over-process irrelevant information during mnemonic decisions, and therefore reducing attentional resources available for such a dysfunctional processing enhances memory. Moreover, the results are crucial for developing rehabilitative interventions tailored to confabulating patients. Training them to double-check the accuracy of their memories may not be useful. In fact, these patients should be trained not to attend, and act upon, their mnemonic impressions.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
