Daily brief research updates from the cognitive sciences
A couple of studies have just been released which look at the brains of newborns and young babies. The results are worrying for any society.
Brain scans of newborn babies from mothers in poverty showed lower brain volumes across all regions of the brain, suggesting less maturity, but also, just as worryingly, that the folds in the brain were fewer and shallower also suggesting a less developed brain and potential functional impairment. This is in comparison to babies born to mothers with higher household incomes.
This is another one to show how poverty can have dramatic consequences and damage society, which can then be perpetuated.
A second paper from the same dataset of 399 mothers showed that the brain of newborns with mothers from areas with high crime rates showed weaker connectivity across multiple regions in the brain in the first few weeks of life.
This shows that poverty and exposure to crime and its stresses can have dramatic impacts on the brains of babies – how long this lasts is not clear but it is obviously a bad start to life for an innocent baby.
Public policies that effect this critical period of life – pregnancy – is therefore a very good idea for society!

No change for a century – children’s backgrounds still predict the same educational outcomes
Educational opportunities have changed dramatically for children over the last century – schools have changed, and college and university admissions have grown. Or so we might think at least. But according to a study out of the University of York, that is not the...
Behaviour at eight helps predict midlife health behaviours
A long-term study in Finland has tracked children from the age of eight until the age of 50 and a new analysis of the data, just published, has looked at some of the correlations between socioemotional behaviour in childhood and later life achievement and health...
Psychedelics and consciousness
Psychedelics change our conscious experience of the world – that is part of their attraction. Now a new study out of John Hopkins Medicine has analysed data on attributions of consciousness to other animals and innate objects by those using psychedelics and how this...
Lower smartphone usage increases wellbeing
So much has been said about smartphone usage in modern times. This ranges from some who say that they are destroying our brain to others who see they benefit our cognition by outsourcing cognitive heavy tasks like remembering lists of phone numbers – thereby freeing...
Modesty preferred for cooperative teams
In an age where it appears that many people are vying for self-esteem especially through social media, this research is interesting. Particularly in business contexts where cooperation is king. Research has previously shown that appearing to be wealthy increases...
Babies born with five from seven functional brain networks
In the 1950s the blank slate theory was the most prominent theory ascribed to babies. They are born blank slates and then their experiences allow them to develop their networks thoughts, associations, etc., and just about everything else. Though this theory is long...
