How long do you want to live? Your expectations for old age matter

by Dr. Jekyll in Lunatic Laboratories

Why do some people want to live a very long time, while others would prefer to die relatively young? In a latest study, a team of researchers investigated how long young and middle-aged adults in the United States say they want to live in relation to a number of personal characteristics. The results showed that more than one out of six people would prefer to die younger than age 80, before reaching average life expectancy.

Psychopathy Personality Inventory—Revised (PPI-R) Scale 

by Rita Handrich in The Jury Room

We wrote about this scale in our last post when researchers (trying to convince the reader there is such a thing as a good psychopath for you to hire) used it in a study of German adults. The PPI-R is apparently a measure of psychopathy that is able to “detect relatively mild levels of psychopathy […]

ALSPAC says maybe to link between prenatal paracetamol exposure and childhood behavioural difficulties

by Paul Whiteley in Questioning Answers

ALSPAC - the Avon Longitudinal Study of Parents and Children - continues to give in research terms as today I approach the findings reported by Evie Stergiakouli and colleagues [1]. They observed that: "Children exposed to acetaminophen [paracetamol] prenatally are at increased risk of multiple behavioral difficulties, and the associations do not appear to be explained by unmeasured behavioral or social factors linked to acetaminophen use insofar as they are not observed........

Too much activity in certain areas of the brain is bad for memory and attention

by Dr. Jekyll in Lunatic Laboratories

Neurons in the brain interact by sending each other chemical messages, so-called neurotransmitters. Gamma-aminobutyric acid (GABA) is the most common inhibitory neurotransmitter, which is important to restrain neural activity, preventing neurons from getting too trigger-happy and from firing too much or responding to irrelevant stimuli.

Autism and/or ADHD in Down's syndrome

by Paul Whiteley in Questioning Answers

"High rates of ASD [autism spectrum disorder] and ADHD [attention-deficit hyperactivity disorder] were found: 17 (42%) and 14 (34%) of the 41 children met DSM criteria for ASD and ADHD respectively."That was the conclusion reached in the study by Ulrika Oxelgren and colleagues [1] looking at the "prevalence of autism spectrum disorder (ASD) and attention-deficit-hyperactivity disorder (ADHD) in a population-based group of children and adolescents with Down syndrome." The populatio........ Read more »

"Theory of mind is not theory of emotion"

by Paul Whiteley in Questioning Answers

A rather interesting paper by Beth Oakley and colleagues [1] (open-access might be available here) appeared recently providing a "cautionary note on the Reading the Mind in the Eyes Test" [2], one of the premier assessments thought to offer a performance-based measure "involving mental state attribution and complex facial emotion recognition from photographs where only the eye region of the face is available."Most people with some knowledge about autism research history will have heard about the........

Are Teaching and Learning Coevolved?

by Joshua Fisher in Text Savvy

Discussions in education are increasingly focused on "how students learn," and it seems to be widely accepted that teaching should adjust itself to what we discover about this. But if teaching is as natural a human faculty as learning, then this may be only half the story. How students (naturally) learn might be caused, in part, by how teachers (naturally) teach, and vice versa. And learners perhaps should be asked to adjust to what we learn about how we teach as much as the other way ........ Read more »

'I miss you so much': How Twitter is broadening the conversation on death and mourning

by Dr. Jekyll in Lunatic Laboratories

Death and mourning were largely considered private matters in the 20th century, with the public remembrances common in previous eras replaced by intimate gatherings behind closed doors in funeral parlors and family homes. But social media is redefining how people grieve, and Twitter in particular -- with its ephemeral mix of rapid-fire broadcast and personal expression -- is widening the conversation around death and mourning.

What are we getting wrong in neuroscience?

by neurosci in Neuroscientifically Challenged

In 1935, an ambitious neurology professor named Egas Moniz sat in the audience at a symposium on the frontal lobes, enthralled by neuroscientist Carlyle F. Jacobsen's description of some experiments Jacobsen had conducted with fellow investigator John Fulton. Jacobsen and Fulton had damaged the frontal lobes of a chimpanzee named "Becky," and afterwards they had observed a considerable behavioral transformation. Becky had previously been stubborn, erratic, and difficult to train, but post-operat........ Read more »

Polycystic ovary syndrome (PCOS) and risk of psychiatric disorder

by Paul Whiteley in Questioning Answers

"Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting 5-15% of reproductive-aged women and characterized by high levels of circulating androgens."OK, go on."Women with PCOS had higher risks for a range of psychiatric disorders not shown before. Elevated risk in their siblings suggests shared familial factors between PCOS and psychiatric disorders."So said the findings reported by Carolyn Cesta and colleagues [1] who using Swedish national register data concluded that there ma........

Psychopaths brains work differently—at least when  they are criminal psychopaths

by Rita Handrich in The Jury Room

This will shock you, or maybe relieve you: Psychopaths are different from the rest of us. Here’s another article saying there are measurable differences in how the brains of how criminal psychopaths work (and look) when compared to non-criminal psychopaths (those who have psychopathic traits but have not been convicted of criminal offenses) and non-psychopaths.

Childhood inflammation and hypomanic symptoms in young adulthood?

by Paul Whiteley in Questioning Answers

"Higher levels of systemic inflammatory marker IL-6 in childhood were associated with hypomanic symptoms in young adulthood, suggesting that inflammation may play a role in the pathophysiology of mania."That was the conclusion reached by Joseph Hayes and colleagues [1] (open-access available here) who drew on data derived from the excellent resource that is ALSPAC ("Charting the health of 14,500 families in the Bristol area to improve the health of future generations").

Wait, let me google it. On the fall (and rise?) of human memory.

by gdw in FictionalFieldwork

Ruins of a memory palace Once upon a time, there were no computers. And yet, even in the ancient days when writing was not widespread, people told gigantic tales or recited poems of epic proportions. Often more than once. Admittedly, they probably changed a bit along the way, but still the plot remained intact. How […]... Read more »

Mercury and autism: where the science currently stands

by Paul Whiteley in Questioning Answers

Yes, I know that on the 'hot potato' scale, to talk about mercury and autism still moves the needle up to somewhere approaching furnace level for some people despite discussions on this heavy metal still figuring in several quarters. This is however a blog based on peer-reviewed science (for the most part) and so with mucho, mucho caveats included I want to draw your attention to the review paper by Janet Kern and colleagues [1] (open-access available here) and the observation that: "The pr........

Can cell phones make you feel less connected to your friends and family?

by Dr. Jekyll in Lunatic Laboratories

In this digital age, with phones at our fingertips, you would think that access to constant communication would make us feel closer to one another. But a new study shows that may not be the case. In fact, cell phone use might actually lead to feeling less socially connected, depending on your gender or cell phone habits.

In Dog Training, Balance Is Off

by CAPB in Companion Animal Psychology Blog

It’s not a good thing when dog trainers describe themselves as ‘balanced’. Here’s why.When you think about balancing dogs, your first thoughts might be of a dog walking along a beam, all nicely balanced and not falling off. Or maybe of a dog posing for a photo with a pile of cookies balanced on their muzzle, to show off how good their balancing skills are.But, unfortunately, this is not what people mean when they refer to ‘balanced’ dog training.Balance is one of those weasel words i........

Slow motion videos and juror perception of time for  intentional acts

by Doug Keene in The Jury Room

New research tells us you may not want to have slow motion videos played at trial if you are the defense attorney. However, if you are the prosecutor—push hard for that video! It’s really a simple lesson: when jurors see slowed down footage of an event, they are more likely to think the person on […]

A dog's dilemma: Do canines prefer praise or food?

A new study suggests that given the choice, many dogs prefer praise from their owners over food. The study is one of the first to combine brain-imaging data with behavioral experiments to explore canine reward preferences.
