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: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
