Men More Likely To Have An Accurate Memory of Unpleasant Experiences

A woman’s memory of an experience is less likely to be accurate than a man’s if it was unpleasant and emotionally provocative, according to research undertaken by University of Montreal researchers at Louis-H Lafontaine Hospital. “Very few studies have looked at how ‘valence’ and ‘arousal’ affect memories independently of each other, that is to say, how attractive or repulsive we find an experience and how emotionally provocative it is,” said corresponding author Dr. Marc Lavoie, of the university’s Department of Psychiatry and the hospital’s Fernand-Seguin Research Center. “Our test relied on photos – we found firstly that highly arousing pictures blur women’s capacity to determine whether they’ve seen it before, and secondly that women have a clearer memory of attractive experiences than men. Arousal has an enhancing effect on the memory of men however, as does ‘low valence’ or unpleasantness.” (more…)

Diamonds, Silver and the Quest for Single Photons

*Tiny crystal towers enlighten understanding of photon emission, could inspire diamond microchips for quantum computing*

Building on earlier work, scientists and engineers recently developed a manufacturing process that allows them to craft an assortment of miniature, silver-plated-diamond posts that enable greater control of light producing photons at the atomic scale. The research could prove important for future generations of quantum computers.

Prior research demonstrated how nanowires carved in impurity-laden diamond crystal could efficiently emit individual photons, an important discovery for using light to rapidly read and write quantum-based data. (more…)

Think you’ll ace that test? Think again. Then start studying

We hold many beliefs about memory—for instance, if you study more, you learn more. We are also constantly making judgments about particular instances of learning and remembering—I’ll never forget this party! That was easy to understand. I’ll ace it on the test.

But do beliefs influence judgments, and how do judgments affect memory performance? “There’s a disconnect among beliefs, judgments, and actual memory,” says Williams College psychologist Nate Kornell. Ask people to predict how or what they will learn and “in many situations, they do a breathtakingly bad job.” (more…)
