Penn State researchers have developed a computer program that mimics the results when a human appraises a task as threatening and feels worried before starting.
Dr. Frank Ritter, associate professor in the School of Information Sciences and Technology (IST), says, "In this study, we used our program to mimic the results achieved by people who can be seen as having a type of math anxiety. However, the program could also be used to study the effects of feeling threatened or worried before driving a car, using a computer or other stressful task -- and to help develop remedial strategies."
The results were described in a paper, "Using Cognitive Modeling To Study Behavior Moderators: Pre-Task Appraisal and Anxiety," presented this month at the 48th Annual Meeting of the Human Factors and Ergonomics Society in New Orleans. The authors are Ritter, Andrew Reifers, an IST doctoral student; Laura C. Klein, assistant professor of biobehavioral health, College of Health and Human Development; Karen Quigley, New Jersey Medical School, University of Medicine and Dentistry of New Jersey; and Mike Schoelles, Rensselaer Polytechnic Institute.

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
