New study shows a link between caregiver and infant cognition
New research using experimental and brain imaging tools has shown that there is an association between caregiver and child cognition.
Researchers from the University of Nottingham’s School of Psychology examined infant visual cognition – important for how they navigate the world around them, engage with objects, and learn new concepts.
The team explored whether caregiver cognitive functions would be associated with infant visual cognition.
Around 90 families from East Midlands area who had infants between the ages of six and 10 months took part in the study in the Infant and Toddler Lab in the School of Psychology at the University of Nottingham.
During their visit, both caregivers and their infants participated in experimental tasks while the researchers measured their behavioural responses and brain function using functional near-infrared spectroscopy (fNIRS).
In this technique, caregivers and infants wear caps with sensors that shine near-infrared light to measure brain function. Infants and caregivers were presented with colourful changing shapes on a TV screen and researchers examined how they both looked at and switched their gaze between the shapes.
Caregivers also completed an inhibitory control task (how they respond to some stimuli and inhibit their response to others) and questionnaires that assessed how they regulated their behaviours.
The team found that infant visual cognition was linked to two aspects of caregiver cognition – their own visual cognition and behavioural regulation. Specifically, infants’ abilities to detect change was linked to their caregivers’ abilities to also detect change and efficiently monitor and/or inhibit their behaviours.
In addition to behavioural links, the team also found a link between caregiver and infant brain function – in regions in the parietal cortex, an area important for attending to objects in space, working memory and attention.
Dr. Sobana Wijeakumar, Assistant Professor in the School of Psychology who led the research, said: “We are excited about these findings. We know from later in development that there are links between caregiver cognition and child cognition.
“It is promising to see these associations in the first year of life both in behaviour and brain function. In the future, these findings could potentially be used to customise interventions based on caregiver behavioural preferences.
We are also excited about the next stage of our work which tackles whether these associations are linked to how caregivers and infants interact with one another during play time.”
One of the families commented: “Learning that there is a link between my own and my baby’s behaviour and brain development is fascinating. We know that as they get older, they start to ‘copy’ our behaviours but trying to examine how our brains could also be similarly wired – blows my mind.”
The research has been published in the journals – Infant Behaviour and Development and Infant and Child Development.

Poor mental health, poverty and pollution significantly raise women’s heart failure risk – study
Poor mental health, poverty and pollution can raise women’s heart failure risk, with up to one in four cases potentially preventable, a study has found.
UK Biobank data from more than 230,000 women suggest that depression, socioeconomic hardship and exposure to polluted environments are linked to a significantly higher risk of heart failure in women.
Heart failure happens when the heart becomes too weak or too stiff to pump blood effectively around the body.
High blood pressure, high cholesterol, smoking and diabetes are among the better-known risk factors often targeted in public health campaigns.
Peige Song from China’s Zhejiang University and her team found that living in polluted areas, having poor mental wellbeing, facing socioeconomic deprivation and experiencing chronic inflammatory conditions such as lupus, in which the immune system attacks the body’s own tissues, make women more prone to heart failure.
These risks, however, are often overlooked.
The researchers found that mental wellbeing, environmental exposures, socioeconomic circumstances and reproductive history together contributed almost as much risk for heart failure as all well-known risk factors combined.
The study also found that risk rises with socioeconomic hardship and chronic inflammatory conditions such as lupus or rheumatoid arthritis, approaching the impact of conventional risk factors.
Song said: “[The study] is a call to redefine prevention in women’s cardiovascular health, integrating biological, psychosocial and structural determinants into a unified, equitable approach.
“One in four heart-failure cases in women could be prevented if all under-recognised risk factors were eliminated, assuming causal relationships.”
While completely eliminating all risks is not realistic, Song said “even partial reductions through better mental health services, social equity policies and environmental regulations could yield significant public health benefits”.
Catherine Pirkle, a women’s health specialist at the University of Hawaiʻi at Mānoa in the US, who was not involved in the study, said: “These calculations show convincingly that under-recognised and female-specific risk factors contribute significantly to heart failure in women, independently of the well-established ones.”
Song said: “It’s important to understand that heart health is influenced by more than just blood pressure or cholesterol.
“Factors like mental wellbeing, reproductive milestones and socioeconomic conditions all matter. Awareness and advocacy for comprehensive, gender-sensitive care are key.”
Resistance training improves hip strength, balance and flexibility during menopause and may also improve lean body mass, research suggests.
A study of 72 active women aged 46 to 57 found those who completed a 12-week supervised programme saw greater gains than those who kept to their usual exercise routines.
None of the participants were taking hormone replacement therapy.
The supervised, low-impact resistance exercise programme focused on strength at the hip and shoulder, dynamic balance and flexibility.
Participants used Pvolve equipment, including resistance bands and weights around the hips, wrists and ankles, and also lifted dumbbells of varying loads.
Women in the resistance training group showed a 19 per cent increase in hip function and lower-body strength, a 21 per cent increase in full-body flexibility and a 10 per cent increase in dynamic balance, meaning the ability to stay stable while moving.
Those in the usual activity group did not show any significant improvements.
Previous studies have assessed the decline in lower limb strength and flexibility during menopause, but this is said to be the first study to compare the effect of resistance training on muscle strength and mass before, during and after menopause.
This was done by including participants in different phases of menopause rather than following the same participants over a long timeframe.
Francis Stephens, a researcher at the University of Exeter Medical School in the UK, said: “These results are important because women appear to be more susceptible to loss of leg strength as they age, particularly after menopause, which can lead to increased risk of falls and hip fractures.
“This is the first study to demonstrate that a low-impact bodyweight and resistance band exercise training programme with a focus on the lower limbs, can increase hip strength, balance, and flexibility.
“Importantly, these improvements were the same in peri- and post-menopausal females when compared to pre-menopausal females, suggesting that changes associated with menopause do not mitigate the benefits of exercise.”
Although one of the researchers sits on Pvolve’s clinical advisory board, the researchers said the company did not sponsor the study or influence its results.
Stephens added that any progressive resistance exercise training focused on lower-body strength is likely to yield the same results.
He said: “The important point is for an individual to find a type of exercise, modality, location, time of day etc., that is enjoyable, sustainable, and improves everyday life.
“The participants in the present study reported an improvement in ‘enjoyment of exercise,’ and some are still using the programme since the study finished.”
Kylie Larson, a women’s health and fitness coach and founder of Elemental Coaching, who was not involved in the study, said the results were compelling.
She said: “This is particularly exciting for those that tend to think of menopause as ‘the end’. The study proves that if you incorporate strength training you can still make improvements to your muscle mass and strength, which will also have a positive ripple effect to your ability to manage your body composition.
“In addition, staying flexible and being able to balance are both keys to a healthy and functional second half of life.”
Participants in the study did four classes a week for 30 minutes each session, but Larson said even half that amount of strength training can go a long way, particularly if you emphasise progressive overload, which means gradually increasing muscle challenge through more weight.
Larson said: “Gradually increasing the challenge is what drives real change.
“Lifting heavier over time is what builds strength, protects your bones, and keeps your body resilient through menopause and beyond.”
France will reimburse reusable period products for women under 26 and those on low incomes, in a move aimed at tackling period poverty.
The measure is expected to help 6.7m people, almost a tenth of France’s population of 69m, from the start of the next academic year in the autumn.
Women under 26 with a state health insurance card, as well as women of all ages who receive special healthcare support because of limited income, will be able to claim reimbursement after buying the products from a pharmacy. The cost will be covered through the country’s social security system.
Parliament approved the measure as part of the country’s social security budget for 2024. However, no decree was issued to bring it into force, prompting anger among feminist groups and companies making the sustainable sanitary items.
A survey of 4,000 women in France in November found that one in ten had used alternatives to mainstream period products, such as ripped-up clothes, because of tight budgets, according to French charity Dons Solidaires.
France cut sales tax on period products from 20 per cent to 5.5 per cent in 2016. In 2020, Scotland became the first country in the world to sign into law free universal access to period products in public buildings.
