Working memory retains visual details despite distractions

20.01.2006


The ability to retain memory about the details of a natural scene is unaffected by the distraction of another activity and this information is retained in "working memory" according to a study recently published in Journal of Vision, an online, free access publication of the Association for Research in Vision and Ophthalmology (ARVO). These results reinforce the notion that humans maintain useful information about previous fixations in long-term working memory rather than the limited capacity of visual short-term memory (VSTM).



Memory has traditionally been divided into VSTM and long-term memory (LTM). VSTM usually involves the retention of about four objects at a time. This is followed by either information loss or the transfer of this information into LTM. This study provides further evidence that an intermediary "working memory" better describes the nature of information retained while engaged in a particular task.

In the study conducted by Oxford Brookes University Professor David Melcher, participants were asked to view a photograph of a natural scene for 10 seconds. Following the initial viewing, they were asked to silently read a paragraph for 60 seconds, repeating if necessary, or view an image with five colored square for 60 seconds. The participants were then asked questions about the first scene they had viewed. The results show that the addition of the reading task had no measurable influence on the average performance for either color, shape or location questions compared to other trials which involved just a 10-second delay between the viewing and the testing.


According to Melcher, "These results provide further evidence that visual scenes are special and that memory for real scenes involves a system with different properties than that used for words or simple shapes. We are currently examining how this memory system develops in children, how it is affected by aging and how it interacts with attention and disorders of attention."

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...

Im Focus: New laser joining technologies at ‘K 2016’ trade fair

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
