People-calculating: open doors and closed doors

May 26th, 2015

RosenbaumWhether one person holds a door open for another is not simply a question of etiquette, says a study by Joseph P Santamaria and David A Rosenbaum [pictured here] of Pennsylvania State University. No, they say. Nothing simple about it.

Santamaria and Rosenbaum worked to pursue the answer through a tangle of belief, logic, probability, perception and calculation. Their study, Etiquette and Effort: Holding Doors for Others, was published in 2011 in the journal Psychological Science. It is, one way or another, a gripping read....

Improbable Swedish TV: Ignobelseminarium in Stockholm

May 25th, 2015

The Swedish public television network SVT filmed the Ig Nobel show at Boulevardteatern in Stockholm on March 25, 2015. Two months later, SVT broadcasted their video of that night. It is (at least for a while) available on SVT’s UR Play web site. (Many thanks to publishers Fri tanke förlag, to Boulevardteatern, and to dapper neuroscientist Gustav Nilsonne for helping arrange the event!)

Here are links to highlights from that show (click on each image to see the video).

Sabine Begall and Pascal Malkemper tell how their team, in the Czech Republic and Germany, gathered evidence that dogs, while excreting, often align their body axis with earth’s north-south magnetic field lines:

Jaroslav Flegr, of the Czech Republic, tells how he and others learned more about the question of whether it is mentally hazardous to own a cat.

Andrea Rapisarda tells how he and his colleagues in Italy discovered that, for most organizations, promotions produce the best results if people are promoted at random.

‘Why It’s So Hard to Understand Opera’

May 25th, 2015

Gluck_OrpheeIf you’ve ever asked yourself why it’s so hard to understand opera, then you could turn to the work of Bertram M. Schwarzschild for explanation(s). He wrote an article on the subject which featured in the journal New Zealand Acoustics, 17(3), pp.15- 20 . (2004), entitled: ‘Why It’s So Hard to Understand Opera

 “A frustrated listener might well define grand opera as musical theatre where you have a hard time making out the words even when they’re being sung in your own language.
Conceding the point, many opera houses nowadays always flash surtitles above the proscenium. Comprehension is particularly difficult in the higher reaches of the soprano register.”

Note: The article was originally published in Physics Today, March 2004, under the title “Acoustics Experiment Shows Why It’s So Hard to Make Out the Heroine’s Words at the Opera”.

BONUS: An opera that some may enjoy finding difficult to understand.

Some people prefer orange skin

May 25th, 2015

Having or making your skin be orange-colored can help make some persons more attractive than other persons, to certain persons, for mating purposes, suggests this study:

perrettFruit over sunbed: Carotenoid skin colouration is found more attractive than melanin colouration,” Carmen E. Lefevre and David I. Perrett [pictured here], Quarterly Journal of Experimental Psychology, vol. 68, no. 2, 2015. (Thanks to Neil Martin for bringing this to our attention.) the authors, at Leeds University, Northumberland University, and the Unviversity of St. Andrews, UK, explain:

“Skin colouration appears to play a pivotal part in facial attractiveness. Skin yellowness contributes to an attractive appearance and is influenced both by dietary carotenoids and by melanin. While both increased carotenoid colouration and increased melanin colouration enhance apparent health in Caucasian faces by increasing skin yellowness, it remains unclear, firstly, whether both pigments contribute to attractiveness judgements, secondly, whether one pigment is clearly preferred over the other, and thirdly, whether these effects depend on the sex of the face….

“We show that carotenoid colouration is consistently preferred over melanin colouration when levels of colouration are matched. In addition, we find an effect of the sex of stimuli with stronger preferences for carotenoids over melanin in female compared to male faces, irrespective of the sex of the observer…. Taken together, our findings provide further support for a carotenoid-linked health-signalling system that is highly important in mate choice….

“In Western countries, tanning is popular and tanned skin is seen as attractive (Smith, Cornelissen, & Tovée, 2007), perhaps because it indicates status and wealth (ability to spend time tanning and holidaying; see Etcoff, 1999).”
