Maybe a little anxiety couldn't hurt
As I've mentioned before, I come from a long line of worriers. So I was pleased to get a press release about a new study that suggested a little fretting might be a good thing. I felt compelled to call Gregory Samanez-Larkin, the Stanford psychology grad student who's the study's lead author, although I was a little anxious about what he might have to say.
A little anxiety pays sometimes, study shows
Quando l'ansia gioca d'anticipo
L'ansia "anticipatoria" è quella che ci fa stare sulle spine settimane prima di un esame o di una prova particolarmente impegnativa. A volte può essere un problema. Pare invece che sia l'asso nella manica di broker, consulenti finanziari e operatori di borsa: li aiuta, sembra, ad agire con lungimiranza.
Why do we make bad decisions? Findings from a new science
We all make bad decisions from time to time, decisions that diminish our well-being either right away or years later. However, some of these bad decisions are more than occasional, rising to the level of chronic patterns in the general population. Many of these recurring behaviors seemingly defy rational explanations.
Older people are less upset by the thought of losing money
A team at Stanford University in California studied how young and old people anticipated winning and losing money, and then reacted when it occurred. They found that older adults had a different response when it came to losses, said psychologist Gregory Samanez Larkin, one of the team that reports the work in the journal Nature Neuroscience.
