Healthy Lungs May Keep Brain Running Smoothly
U.S. News & World Report: Good lung health may help you maintain your brain's processing speed and problem-solving abilities as you age, according to a new study. While reduced lung function had a negative effect on these two types of "fluid" cognitive [thinking] abilities, it was not linked with poorer memory or any significant loss of stored knowledge, the researchers said. Changes in thinking function did not affect lung health. For the study, the research team analyzed data from 832 people, aged 50 to 85, in Sweden who were followed for up to 19 years. The findings were published recently of the journal Psychological Science. Read the whole story: U.S. News & World Report

Worriers who feel guilty before doing anything wrong make best partners, research finds
The Telegraph: A new study found that worriers who begin to chastise themselves at the mere thought of doing something wrong are less likely to behave immorally as a result of their unwavable conscience. In contrast some 30 to 40 per cent of people fit the opposite category and give very little forethought to how their actions will make them feel – a recipe for unethical behaviour, psychologists say. Women are more likely to feel pre-emptive guilt than men, and older people tend to anticipate feelings of shame and regret better than those who are younger and less experienced in life.

Quanto costa la felicità (How much does happiness cost?)
la Repubblica: Se potessimo avere, 3500 euro al mese... Saremmo certi di trovare la felicità? Ricerche alla mano, parrebbe proprio di sì. L’importante, come consigliava nel ’39 la famosa canzone Mille lire al mese, è non esagerare. Ovvero: non rischiare di guadagnare di più. Gli studiosi sostengono infatti che esiste un “numero magico”, una cifra di reddito sopra la quale è inutile andare, perché la felicità non aumenta.

The ‘human touch’ in computer-based learning
The Washington Post: The importance of a good relationship between teacher and student is no surprise. More surprising is that the “human touch” is so powerful it can improve computer-based learning. In a series of ingenious yet simple experiments, Rich Mayer and Scott DaPra showed that students learn better from an onscreen slide show when it is accompanied by an onscreen avatar that uses social cues. Eighty-eight college students watched a four-minute Powerpoint slide show that explained how a solar cell converts sunlight to electricity. It consisted of 11 slides and a voice-over explanation.

How We Enjoy Self-Interest Without Feeling Selfish
LiveScience: Humans are often torn between selfish and social impulses. Sometimes when we make a decision in our own self-interest, we feel guilty for putting ourselves before others. But new research suggests we can clear our conscience if we feel like a selfish outcome has been decided for us. "Often people really want to act in a selfish manner," researcher Jonathan Berman, of the University of Pennsylvania's Wharton School, said in a statement. "But they don't do so, because they know they would feel selfish if they did." Read the whole story: LiveScience

Why do jokes sometimes fall flat?
The Globe and Mail: Laughter may be the best medicine. But how do you administer it? Scientists have long recognized the wide-ranging health benefits of humour, from reducing stress and improving morale to even decreasing the risk of cardiovascular disease. Yet pinpointing what actually makes things funny has been elusive thus far. At the University of Colorado, Boulder, marketing and psychology professor Peter McGraw has been mulling over this puzzle since 2008 and at last, he and his fellow researchers have put a finger on an answer: Humour equals tragedy plus time.
