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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
