Five-year-olds can see through your bravado

by BPS Research Digest in BPS Research Digest

Imagine you wanted to lie to a five-year-old. "The toy shop is closed Billy," you say, "it always closes at 2pm on a Monday." You reason that if you make this announcement with confidence, then Billy is sure to believe you.It's not a bad strategy. In a new study involving nearly a hundred kids aged four to five, they were more likely to believe statements made by a woman who spoke and gestured with confidence, than those made by a woman who was hesitant and uncertain. In this case, the women's c........ Read more »

Can a brain scan tell us anything about the art of creative writing?

by BPS Research Digest in BPS Research Digest

When an accomplished creative writer gets on with their craft, their brain operates in a somewhat different way to a novice's. A new imaging study suggests that the expert approach may be more streamlined, emotionally literate, and initially unfiltered.Katharina Erhard with her colleagues from the German universities of Greifswald and Hildesheim asked participants to read a fragment of a story, to brainstorm what could continue the narrative, and then, for two minutes, to write a continuation of........

Autism, parental concerns and socioeconomic status

by Paul Whiteley in Questioning Answers

I'd like to think that there are some rather important messages to be taken from the paper by Xiang Sun and colleagues [1] on level of parental concern, socioeconomic status (SES) and risk of autism. Not only did the authors conclude that: "a higher SES was not associated with the risk of having ASC [autism spectrum conditions]" they also found that: "No child met ASC criteria where parents expressed no concerns".Do you prefer "fashion victim" or "ensembly challenged"?SES - including variab........

Dude, wheres my Hover Car? Oh wait…

by Gabriel in Lunatic Laboratories

We all (of a certain age) remember the Jetsons, a futuristic family with hi-tech gadgets and gizmos. However, nothing said, “the future is here” quite like things hovering. Even in the movie Back to the future, they have hover boards and flying cars. Unfortunately we don’t, which is a shame because according to the 1950’s we are the future, we should have hover-cars and hover boards… well the wait is over. Yep, introducing the first real hover board!... Read more »

Sleep Problems in Alcoholism Treatment

by William Yates, M.D. in Brain Posts

In a previous post, I summarized a research study six month outcome of insomnia in a group of subjects treated for alcoholism.This study found a high persistence of insomnia despite reduction, and in many cases abstinence, from alcohol.A second study recently published by investigators at the National Institute of Health provides some additional insight into this topic.Gwenyth Wallen and colleagues studied a series of 164 participants admitted to a 4-6 week inpatient program for alcohol dependen........

Not Quite Dead Yet

by Mark E. Lasbury in The 'Scope

History shows that premature burial was more common than people might want to believe. Many burial traditions, including the Irish wake, stem from trying to prevent someone from being buried alive. How might this happen? Several medical conditions can lead to a poor decision on burial time. ... Read more »

Antibiotics and childhood obesity: a weighty correlation

by Paul Whiteley in Questioning Answers

It's been a few weeks since the publication of the paper by L. Charles Bailey and colleagues [1] correlating early multiple exposure to broad spectrum antibiotics with obesity in infancy. On purpose I've left it a while before talking about this research so as to let the scientific dust settle a little and get a flavour for some of the discussions about this research (see here and see here).You're a true vulgarian, aren't you?A few details about the Bailey study first:Looking at the el........

A Venusian Mystery Explored Once More

by Gabriel in Lunatic Laboratories

Venus, the place where women are from... supposedly. To say Venus has a harsh climate would be an understatement, this is one of many reasons why we will never (or maybe not soon) see a "long lasting" Venus rover counterpart to our Mars rover missions. Still, the planet (much like all the other plants) can teach us a lot about not just our own origins, but the origins of the universe. Also like all our neighbor planets Venus is hiding something beneath its brilliant shroud of clouds, a mystery t........ Read more »

Moral Time: Does Our Internal Clock Influence Moral Judgments?

by Jalees Rehman in The Next Regeneration

Does morality depend on the time of the day? The study "The Morning Morality Effect: The Influence of Time of Day on Unethical Behavior" published in October of 2013 by Maryam Kouchaki and Isaac Smith suggested that people are more honest in the mornings, and that their ability to resist the temptation of lying and cheating wears off as the day progresses. In a series of experiments, Kouchaki and Smith found that moral awareness and self-control in their study subjects decreased in the........ Read more »

Does Literary Fiction Challenge Racial Stereotypes?

by Jalees Rehman in Fragments of Truth

Reading literary fiction can be highly pleasurable, but does it also make you a better person? Conventional wisdom and intuition lead us to believe that reading can indeed improve us. However, as the philosopher Emrys Westacott has recently pointed out in his essay for 3Quarksdaily, we may overestimate the capacity of literary fiction to foster moral improvement. A slew of scientific studies have taken on the task of studying the impact of literary fiction on our emotions and thoughts. Some of t........ Read more »

Persistent Insomnia and Alcoholism

by William Yates, M.D. in Brain Posts

Sleep problems complicate the treatment and recovery in alcoholism. Heavy alcohol consumption modifies the nature of sleep architecture.A high blood alcohol concentration at bedtime may promote sleep early in the sleep cycle.However, as alcohol levels decline, sleep is often interrupted with limiting rapid eye movement (REM) sleep duration.Shortened total sleep time with alcohol can produce a lack of feeling well rested on awakening.For those with alcoholism or alcohol dependence, successfu........

Decades of lie detection research has been unrealistic

by BPS Research Digest in BPS Research Digest

According to decades of psychology research, most people, including law enforcement professionals, are useless at detecting lies. But in a new paper, a team led by Tim Levine argues that nearly all previous research has been unrealistic. The field has been dominated by studies that place the "lie detector" in a passive role, tasked with spotting "tells" leaked by the liar. But this just isn't how deception detection works in real life, say Levine and his team. Rather, the interrogator interacts ........ Read more »
