When the music stops: Intensive instrument playing can lead to movement disorders

by Dr. Jekyll in Lunatic Laboratories

A musician takes up his/her violin and starts to play, but rather than gripping the strings, the fingers seize up--and this happens every time he/she takes up the instrument. Such a movement disorder--the so-called focal dystonia-- is a dramatic disease for those affected, which has thus far barely been studied.

22q11.2 Deletion Syndrome and 'a highly increased risk of schizophrenia spectrum disorders'

by Paul Whiteley in Questioning Answers

22q11.2 deletion syndrome has turned out to be something of real interest to this blog. Not only because of the reported connection to the presentation of autism (see here) including some suggestion of a role for the immune system (see here) but also because of the idea that certain somatic comorbidity linked to the gastrointestinal (GI) tract might also figure as part of the presentation of at least some cases of Del22 (see here). Said GI issues have also cropped up across quite a few other lab........ Read more »

Our collective memory, like individual memory, is shockingly fallible

by BPS Research Digest in BPS Research Digest

By guest blogger Laura SpinneyWhat were the greatest human catastrophes of the 20th century? When asked this question, most people answer the Second World War, followed by the First World War. The former killed around 50 million people, the latter 17 million. But there was another catastrophe that dwarfed both of these, that is rarely mentioned. The influenza pandemic of 1918-1920, better known as the Spanish flu, killed at least 50 million people worldwide, and perhaps as many as 100 million.Wh........ Read more »

Fatigue and severe behaviour problems associated with autism

by Paul Whiteley in Questioning Answers

Challenging behaviours or behavioural crisis in relation to autism is a topic that has graced this blog before (see here). Covering a whole spectrum of issues ranging from aggression (self and/or directed against others) to various other quite undesirable presentations (such as smearing) quite a lot of behaviour can potentially fall into this description.Without heading too far into the possible [often very individual] reasons as to why challenging behaviours occur and their meaning (see he........

Our brain can store information of the entire web (or more)

Memory capacity of brain is about 10 times more than previous estimations, which is in the petabyte range, i.e. almost equivalent to the entire Web.

Published in:

Study Further:

Memories and thoughts in our brain are caused by a distinct pattern of chemical and electrical activity. Our brain has branches of neurons, which are connected to each other through synapses.

Capgras syndrome is a strange disorder in which the sufferer becomes convinced that someone close to them has been replaced by an impostor.

Ryan Darby and David Caplan in a new paper in the journal Neurocase. The authors describe the case of a man who believed that his cat was in fact a different cat.

Teams are more creative when their leader is confident in her or his own creativity

by BPS Research Digest in BPS Research Digest

If you’re wondering who to appoint to run a team with creative goals, you might favour a non-creative, reasoning that it’s down to the team members to generate creativity, with the person at the top acting more as driver and dogged coordinator. However, new research in Organizational Behavior and Human Decision Processes suggests that teams produce more creative outcomes when their managers have greater confidence in their own creativity.Lei Huang of Auburn University and his collaborators s........

Pendulum swings... prenatal antidepressant exposure not linked to autism or ADHD

by Paul Whiteley in Questioning Answers

"Multiple studies have examined the risk of prenatal antidepressant exposure and risk for autism spectrum disorder (ASD) or attention-deficit hyperactivity disorder (ADHD), with inconsistent results."And..."These results suggest that prior reports of association between prenatal antidepressant exposure and neurodevelopmental disease are likely to represent a false-positive finding, which may arise in part through confounding by indication."'These results' refers to the findings reported by Castr........

Overwhelmed and depressed? Well, there may be a connection

by Dr. Jekyll in Lunatic Laboratories

Ever feel overwhelmed when you are depressed, well the good news is it isn't just you, the bad news is it's probably your brain. Regions of the brain that normally work together to process emotion become decoupled in people who experience multiple episodes of depression, neuroscientists report. The findings may help identify which patients will benefit from long term antidepressant treatment to prevent the recurrence of depressive episodes.

WATCH: Persistence Pays Off For Squirrels

by Jenny Ludmer in Rooster's Report

Surely you can expect that the ubiquitous furry creature — a regular at your public park — is a master problem-solver. After all, squirrels must continuously stockpile acorns and occasionally raid bird feeders, all while playing in traffic and dodging hairy little beasts on leashes. But what personality characteristic most drives these exceptional abilities: persistence or flexibility? ... Read more »

The police believe a lot of psychology myths related to their work

The research, conducted in the UK, also showed that police officers have more confidence than the public in their false beliefs.Chloe Chaplin, a programme facilitator at the London Probation Trust, and Julia Shaw, senior lecturer at South Bank university, recruit........

People who have experienced more adversity show more compassion

In parallel with the difficulties caused by trauma, such as depression and ill health, some people experience positive psychological changes, such as a renewed appreciation for life and increased resilience – a phenomenon psychologists term "post traumatic growth". According to a new study in the journal Emotion, we can add another positive outcome related to adversity – compassion. The more adversity in life a person has experienced, the more compassion they tend to feel and show toward oth........ Read more »
