Spoilers actually enhance your enjoyment
The Guardian: Yes! Vindication! I am one of those people who can't read a book without flicking to the end to check what's going to happen, and it turns out that, rather than being an "impatient idiot who is spoiling it for myself", actually I am very wise. Scientists say so, so it must be true. A study by Nicholas Christenfeld and Jonathan Leavitt of UC San Diego's psychology department, due to be published in the journal Psychological Science, gave subjects 12 short stories, by authors including Agatha Christie, Roald Dahl and John Updike. Some were presented in their classic form, others with spoiler paragraphs, with each version read by at least 30 people. And you know what?

In Future Math Whizzes, Signs of ‘Number Sense’
The New York Times: Children as young as 3 have a “number sense” that may be correlated with mathematical aptitude, according to a new study. Melissa Libertus, a psychologist at Johns Hopkins University, and colleagues looked at something called “number sense,” an intuition — not involving counting — about the concepts of more and less. It exists in all people, Dr. Libertus said, including infants and indigenous peoples who have had no formal education. The researchers measured this intuition in preschoolers by displaying flashing groups of blue and yellow dots on a computer screen. The children had to estimate which group of dots was larger in number.

Love, money and suspicion
Alfred Hitchcock’s 1941 film Suspicion is a masterful psychological study of love and money. Cary Grant plays the charming but irresponsible Johnnie Aysgarth, who dazzles the frumpy Lina McLaidlaw, played by Joan Fontaine. Only after their elopement does Lina begin piecing together the truth about her husband: He is broke, a habitual gambler, a liar, an embezzler—and possibly a killer. Indeed, everywhere Lina looks she sees signs that Johnnie is plotting her murder to secure his fortune. What makes this thriller so powerful is that it plays off two of our most potent human impulses.

Decision Making Changes With Age – and Age Helps!
We make decisions all our lives—so you’d think we’d get better and better at it. Yet research has shown that younger adults are better decision makers than older ones. Some Texas psychologists, puzzled by these findings, suspected the experiments were biased toward younger brains. So, rather than testing the ability to make decisions one at a time without regard to past or future, as earlier research did, these psychologists designed a model requiring participants to evaluate each result in order to strategize the next choice, more like decision making in the real world. The results: The older decision makers trounced their juniors.

Do You Suffer From Decision Fatigue?
The New York Times: Three men doing time in Israeli prisons recently appeared before a parole board consisting of a judge, a criminologist and a social worker. The three prisoners had completed at least two-thirds of their sentences, but the parole board granted freedom to only one of them. Guess which one: Case 1 (heard at 8:50 a.m.): An Arab Israeli serving a 30-month sentence for fraud. Case 2 (heard at 3:10 p.m.): A Jewish Israeli serving a 16-month sentence for assault. Case 3 (heard at 4:25 p.m.): An Arab Israeli serving a 30-month sentence for fraud. There was a pattern to the parole board’s decisions, but it wasn’t related to the men’s ethnic backgrounds, crimes or sentences.

La ricerca che boccia i ricchi “Più egoisti e insensibili”
La Repubblica Italia: Egoista, insensibile e incredibilmente avaro, l'Arpagone di Molière non avrebbe avuto nessun problema ad ammettere che i ricchi sono diversi dai poveri, e che l'abisso che separa le due categorie non sta tanto nelle possibilità economiche quanto in quelle emozionali. Dura da digerire, la sua teoria è stata snobbata in favore di quella della telenovela più famosa del mondo, Anche i ricchi piangono, ma dopo quasi quattro secoli per il commediografo francese è arrivato il momento della rivincita.
