Schizophrenia: Delusion without illusion
Scientists have discovered that schizophrenia sufferers are not fooled by a visual illusion and are able to judge it more accurately than non-schizophrenic observers. The study by UCL (University College London) and King's College London suggests that in everyday life, schizophrenics take less account of visual context. If this is part of a more general failure to deal appropriately with context, it could explain why some sufferers might misattribute people's actions or feel persecuted. (2005-10-24)

There's no faking it -- your sexual partner knows if you're really satisfied
There is no point faking it in bed because chances are your sexual partner will be able to tell. A study by researchers at the University of Waterloo found that men and women are equally perceptive of their partners' levels of sexual satisfaction. The study by the Department of Psychology at Waterloo, identified sexual communication and ability to recognize emotions as important factors that predict accuracy in gauging one partner's sexual satisfaction.

Rating your pain from 0 to 10 might not help your doctor
The most commonly used measure for pain screening -- which asks patients in primary care to rate their current pain from 0 (no pain) to 10 (worst pain) -- may only be modestly accurate, according to researchers from the Indiana University School of Medicine and the University of North Carolina. (2007-09-17)

Blind more accurate at judging size than sighted
Close your eyes and imagine a loaf of bread. With your eyes still closed, estimate with your hands the size of that loaf of bread. Do you think your mental representation is an accurate one? Specifically, how accurately have you gauged its size? According to researchers from the University of Otago in New Zealand, you probably overestimated the size of the bread. That is, unless you are blind. (2005-03-28)

Four-year-olds know that being right is not enough
As they grow, children learn a lot about the world from what other people tell them. Along the way, they have to figure out who is a reliable source of information. A new study, which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, finds that when children reach around 4 years, they start noticing whether someone is actually knowledgeable or if they're just getting the answers from someone else. (2011-08-18)

Using 'minutiae' to match fingerprints can be accurate
A study by the National Institute of Standards and Technology (NIST) shows that computerized systems that match fingerprints using interoperable minutiae templates -- mathematical representations of a fingerprint image -- can be highly accurate as an alternative to the full fingerprint image. NIST conducted the study, called the Minutiae Interoperability Exchange Test (MINEX), to determine whether fingerprint system vendors could successfully use a recently approved standard* for minutiae data rather than images of actual prints as the medium for exchanging data between different fingerprint matching systems. (2006-03-20)
