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.

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
Development and implementation of an advanced automobile parking navigation platform for parking services
To fulfill the requirements of the industry, PolyU researchers developed the Advanced Automobile Parking Navigation Platform, which includes smart devices,...
The world's first electrical car and passenger ferry powered by batteries has entered service in Norway. The ferry only uses 150 kWh per route, which...
On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.
RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.
To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
