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: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
