Person Authentication Using Finger Snapping [study]

When it comes to biometric authorization systems, there are many to choose from – candidates include face recognition, fingerprint recognition, ear recognition, voice recognition, tongue recognition and body odour recognition etc etc. But none is 100% perfect, so there’s always a demand for improvement and innovation. In 2016, a team from the Department of Computer […]

Hole Assessment by Finger and Tongue [research study]

A markedly penetrating report, involving fingers, tongues, and holes: “Differences in the oral size illusions produced by cross-modality matching of peg and hole stimuli by the tongue and fingers in humans,” Bruce Melvin and Robin Orchardson, Archives of Oral Biology, vol. 46, no. 3, March 2001, pp. 209-13. The authors, at the University of Glasgow, […]

Finger licking bad (in rehabilitation units)

The nosocomial problems associated with healthcare professionals repetitively licking their fingers while reviewing hospital charts was first formally documented by Myron M. LaBan, MD FAAPMR – the lead author of a 2004 brief report for the American Journal of Physical Medicine & Rehabilitation (Volume 83, Issue 1, pp. 75-78). The report encouraged healthcare professionals to : […]

Relative Finger Lengths and The Voices of Bankers [research study]

Comes yet another discovery about relative finger lengths. The new study is: “Prenatal exposure to testosterone (2D:4D) and social hierarchy together predict voice behavior in bankers,” Erik Bijleveld, Joost Baalbergen, PLoS ONE, vol. 12, no. 6, June 28, 2017, e0180008. The authors, at Radboud University and Utrecht University, The Netherlands, explain: “Prohibitive voice behaviors are […]

Further finger news from Prof. Manning: Gender Inequality across nations

Still more finger-ratio insights from Professor John T. Manning, the father of finger-length studies. He has a new study: “Digit ratio (2D:4D) and gender inequalities across nations,” John T. Manning, Bernhard Fink, Robert Trivers, Evolutionary Psychology, 12(4), 2014, 757-768. The authors write: “Gender inequality varies across nations, where such inequality is defined as the disproportionate representation […]

‘Fat fingers’ and computer programming languages

The ‘Fat Finger Syndrome’ is a semi-affectionate nickname used by computer programmers – meaning ‘making typing errors’. As anyone who has tried their hand at programming will know, a seemingly tiny error (for a human), for example simply substituting a   ;    for a   :    can render a programme completely unusable. But it […]

Finger-Lengths Pointing at Academic Performance, They Say

A further advance in the campaign to find meaning and importance in a person’s relative finger lengths: “2D:4D Asymmetry and Gender Differences in Academic Performance,” John V.C. Nye, Gregory Androuschak, Desirée Desierto [pictured here], Garett Jones, Maria Yudkevich, PLoS One. 2012;7(10):e46319 “We provide the first evidence of a non-linear, quadratic, relationship between 2D:4D [the relative […]
