Police observers are more observant than ordinary  civilians

by Rita Handrich in The Jury Room

Most research has not shown police to be any more observant than ordinary civilians—even though judges and juries often make assumptions that police witnesses are more reliable than civilian eyewitnesses. New research by Dutch researchers shows that police observers were more aware of details in a drug deal near a hotel which had been recorded […]

The neuroscience of traumatic brain injury

by neurosci in Neuroscientifically Challenged

The Centers for Disease Control and Prevention estimates that as many as 1.7 million people in the United States experience a traumatic brain injury (TBI) each year, over 15% of which are thought to be sports-related. Despite the relatively high prevalence of these injuries, however, it seems we are just beginning to appreciate the true extent of the effects they can have on the brain. Awareness of previously unrecognized consequences to TBI and repeated TBI--along with the realization that........ Read more »

by Paul Whiteley in Questioning Answers

Sex change hormonal treatments alter brain chemistry

by Dr. Jekyll in Lunatic Laboratories

Hormonal treatments administered as part of the procedures for sex reassignment have well-known and well-documented effects on the secondary sexual characteristics of the adult body, shifting a recipient’s physical appearance to that of the opposite sex. New research indicates that these hormonal treatments also alter brain chemistry.... Read more »

Who Are You Wearing?: Does Competition Affect How Women View Luxury?

by Melissa Chernick in Science Storiented

What do you think of when I say “luxury consumption”? Probably something that requires a Robin Leach voice over, right? Now what if I ask you why these luxuries are so valued? Is it because they are of excellent quality? Aesthetically appealing? Highly exclusive? Next, consider the audience for the luxury – who is admiring who? And what does that luxury symbolize? Status? Wealth? Success?A recent paper in Evolutionary Psychology takes a look at these questions and has one of the best title........ Read more »

KPAX002 for Chronic Fatigue Syndrome?

by Paul Whiteley in Questioning Answers

Social Class Differences in Mental Health: Do Parenting Style and Friendship Play a Role?

by Mark Rubin in Mark Rubin's Social Psychology Research Blog

It is now well-established that social class is positively related to mental health. However, researchers remain unclear about the specific processes that underlie the relation between social class and depression. In some recent research, we investigated the potential roles of parenting style and friendship in explaining the relationship between social class and mental health....

Parents influence children’s play of violent video games

by Dr. Jekyll in Lunatic Laboratories

Russell Laczniak, a professor of marketing and the John and Connie Stafford Professor in Business, says given the harmful effects of violent video games, he and his colleagues wanted to better understand how parents influence children’s behavior....

The Labrador Lifestyle

by CAPB in Companion Animal Psychology Blog

A survey of Labrador Retriever owners tells us what they eat, how often they exercise, and where they sleep.A survey of over 4000 people with Labrador Retrievers provides a fascinating insight into the lifestyle of the average Lab. 68% of the dogs were pets, 6% working dogs, and of the remainder the largest group of people did not say (a quarter of overall responses).  Black Labradors were the most common (49%), followed by yellow (27%) and chocolate (21%), with other colours including fox ........

On glyphosate and autism (without scaremongering)

by Paul Whiteley in Questioning Answers

Glyphosate use and autism rates - should I blog about it?Well, after some deliberation I decided it was a topic worthy of an entry. There is some peer-reviewed science discussions behind it and, as per other areas of controversy on the autism research landscape, the idea that 'science is about debate' (why else does everyone keep going on about open-access and transparency) should always prevail.I'm assuming most people have heard of the organophosphonate (that's phosphonate not p........

American placebo – An increase in the placebo response, but only in America?

by Dr. Jekyll in Lunatic Laboratories

A new study finds that rising placebo responses may play a part in the increasingly high failure rate for clinical trials of drugs designed to control chronic pain caused by nerve damage. Surprisingly, however, the analysis of clinical trials conducted since 1990 found that the increase in placebo responses occurred only in trials conducted wholly in the U.S.; trials conducted in Europe or Asia showed no changes in placebo responses over that period....

How do popular kids behave in a cooperative task with a classmate?

by BPS Research Digest in BPS Research Digest

Popular girls showed more skilful leadership than others, popular boys showed less. In classrooms around the world, there's an unwritten hierarchy, with most of the kids knowing each other's standing in terms of popularity. Past psychology research has looked into the ways that children and teens attain this status, including the ability to influence their peers, either in skilful, sensitive ways or through coercion and manipulation. A new study published in the Journal of Experimental Chil........ Read more »

The ASQ-3 and autism screening: has the UK already started?

by Paul Whiteley in Questioning Answers

'Can Screening with the Ages and Stages Questionnaire Detect Autism?' was the research question posed and partially answered in the paper by Sarah Hardy and colleagues [1] recently.Drawing on data from a very healthy sized cohort (~2800 toddlers) who were "screened with the ASQ-3 [Ages and Stages Questionnaire] and M-CHAT-R across 20 pediatric sites" in the United States, researchers suggested that there may be more to see when it comes to the use of ASQ-3 and the complicated topic of ........

Brain networking: behind the cognitive control of thoughts

by Dr. Jekyll in Lunatic Laboratories

The human brain does not come with an operating manual. However, a group of scientists have developed a way to convert structural brain imaging techniques into “wiring diagrams” of connections between brain regions. Three researchers from UCSB’s Department of Psychological & Brain Sciences — Michael Miller, Scott Grafton and Matt Cieslak — used the structure of neural networks to reveal the fundamental rules that govern which parts of the brain are most able to exert cognitive control ........

One more time... the interpregnancy interval and risk of offspring autism

by Paul Whiteley in Questioning Answers

"Children born after an IPI [interpregnancy interval] of <12 months or ≥72 months had a 2- to 3-fold increased ASD [autism spectrum disorder] risk compared with children born after an interval of 36 to 47 months."So said the study results published by Ousseny Zerbo and colleagues [1] looking at the increasingly interesting area of the autism research landscape: the interpregnancy interval (the time from the birth of an index child to the next conception/pregnancy of........

Poop on a Stick Tests Penguins' Sense of Smell

by Elizabeth Preston in Inkfish

Who doesn't enjoy waking to a pleasant smell wafting past? Unfortunately for them, the penguins in a recent study woke up not to pancakes frying nearby, but to less appetizing aromas—for example, feces on a stick. But scientists promise the experiment taught them valuable lessons about a penguin's capabilities. Besides, they let the birds go right back to sleep.

"Research into the sense of smell in birds has a bit of a dubious history," says Gregory Cunningham, a biologist at St. John F........ Read more »

How jurors can be misled by emotional testimony and gruesome photos

by BPS Research Digest in BPS Research Digest

As a juror in a criminal trial, you are meant to make a judgment of the defendant's guilt or innocence based on the evidence and arguments presented before you. In many trials, however, alongside the facts of the case, material and statements are allowed that don't in themselves speak to the culpability of the defendant. In a murder trial, for instance, a parent may take the stand and describe how their life has been destroyed by the loss of their child (the victim in the case). Similarly, the p........ Read more »
