Are the police any better than us at judging the accuracy of eye-witness statements?
by Christian Jarrett in BPS Research Digest
Plenty of research has been conducted into the ability of people, including police officers, to judge whether people are lying: most of us are useless, while new research suggests the police may be better. However, little research has been conducted into whether, deliberate deception aside, people can judge the accuracy of eye-witness statements. This is an important issue given how unreliable eye-witnesses can be, even when they think they're telling the truth.Now Torun Lindholm has made a star........ Read more »

Cynical humor directed towards patients, it is mostly about the culture
by Dr Shock in Dr Shock MD PhD
Patients can say and do funny things no matter how ill or even depressed they are. Medical students are often surprised to find that patients often respond to humor, even in discussions of the most serious consequence. Good humor can promote a conversation with a patient and it can be a bedside skill worth acquiring. [...]... Read more »

Can sign language really help babies get along better?
by Dave Munger in Cognitive Daily
Baby sign language is all the rage these days. Upscale day-care centers and nanny services promote it as a better way of understanding what babies want. Babies have been known to reliably produce signs as young as 5.5 months, and studies have shown that they reliably produce signs significantly earlier than spoken words. As we've reported here, there is no evidence that teaching sign language delays spoken language development.
But is formal sign training effective? Some studies about baby sign........ Read more »

Depression in Parkinson's
by Pallimed Bloggers in Pallimed: a Hospice & Palliative Medicine Blog
Neurology has published a randomized controlled comparison of nortriptyline with paroxetine for depression in patients with Parkinson's disease. It's a rare treat to see a decently designed, controlled trial of depression treatment in a palliative-care-relevant population (when was the last time we've seen a controlled drug trial of depression therapy in advanced cancer patients?).This was an 8 week, NIH-funded, randomized comparison of nortiptyline (starting dose 25 mg), paroxetine CR (startin........

Uaraneida and the origin of silk in spiders
I do quite a bit of writing on spiders. Many entomologists deal with spiders, mites and other arachnids in their everyday working life. They’re important, ubiquitous predators. To this entomology undergrad, they’re essentially honorary insects.
Everyone knows spiders spin webs. They can be organized and beautiful, such as this orb weaver web
They can be complex and [...]... Read more »

Voodoo Correlations in Social Neuroscience
by The Neurocritic in The Neurocritic
The end of 2008 brought us the tabloid headline, Scan Scandal Hits Social Neuroscience. As initially reported by Mind Hacks, a new "bombshell of a paper" (Vul et al., 2009) questioned the implausibly high correlations observed in some fMRI studies in Social Neuroscience. A new look at the analytic methods revealed that over half of the sampled papers used faulty techniques to obtain their results.Edward Vul, the first author, deserves a tremendous amount of credit (and a round of applause) f........

A Cultural Climate Measure from Iron Age Africa

Will VP35 be Ebola's weak link?
by Greg Laden in Greg Laden's Blog
Ebola is a viral disease that only occasionally infects humans, but when it does, he fatality rate is very high. In some population, where culturally determined methods of treating the dead involve a lot of contact with bodily fluids and where people are unaware of techniques to avoid spread of infection and are otherwise at risk, a large percentage of a rural village population can become infected, and the survival rate once infected can be as low as 10%. With increased awareness of how to av........ Read more »

Creating Social Connection Through Inferential Reproduction
by Doctor Spurt in Effortless Incitement
Most of us sometimes anthropomorphise things around us. We do this in various ways - talking to them, seeing similarities between them and proper agents, treating them as though they had beliefs or feelings. We also sometimes impute intentional explanations to non-intentional phenomena, such as the rain -- or the supernatural being -- that 'knew' there was a picnic on the go.Most of us are also sometimes lonely. Do loneliness and anthropomorphising have anything to do with each other? The author........ Read more »

The Interactive Effect of Cultural Symbols and Human Values on Taste Evaluation
by Doctor Spurt in Effortless Incitement
I've previously reported on a few studies showing some of the ways that taste evaluation isn't a simple response to the physical properties of what is tasted. Actually, now that I check I've only blagged about one so far: We've seen how the same wine (at least when delivered as sips that aren't being paid for) is preferred when it is thought to cost more. But there will be more on this topic, because I enjoy running interference at my wine tasting group.This paper reports an attempt to find out ........ Read more »
