A parent’s genes can influence a child’s educational success, inherited or not

A new study led by UCL researchers confirms that genetic inheritance has a significant impact on educational outcomes. However, the study also reveals that parent genes that aren't directly inherited can shape parents' education levels and subsequently influence their children's learning environment, affecting their academic success.

Not only humans got talent, dogs got it too!

A new study published in Scientific Reports found that a handful of dogs learn multiple toy names effortlessly, despite struggling with object labels. The research suggests that talent in a specific field may not be exclusively human, with gifted word learner dogs displaying exceptional learning capacity.

Largest-ever pre-adolescent brain activation study reveals cognitive function maps

A new study provides valuable information on the cognitive processes and brain systems underlying adolescent development. The data from the largest longitudinal neuroimaging study to date reveals which brain regions are involved in key psychological processes, including cognitive control, reward processing, and social/emotional function.

Ant soldiers don't need big brains

A study published in BMC Zoology found that ant soldiers have smaller brain sizes than workers despite being larger, as their tasks place less cognitive demand. This suggests that investment in brain development may be reduced for individuals with simpler behaviors.

Patients and families who experience delirium report more distress than those who do not

Researchers found that delirium episodes cause distress for both patients and their families, with severity playing a role in emotional pain. The Delirium Burden questionnaire provides a reliable tool to measure this experience, potentially aiding future clinical trials in finding solutions.

Living close to green spaces is associated with better attention in children

A recent study published in Environmental Health Perspectives found that children who live close to green spaces have improved attention skills. The study analyzed data from over 1,500 children and showed a positive correlation between residential exposure to greenness and better scores on attention tests.

White matter structure in the brain predicts cognitive function at ages 1 and 2

A new study published in Proceedings of the National Academy of Sciences found that patterns of white matter microstructure present at birth and after birth predict cognitive function in children at ages 1 and 2. The study used diffusion tensor imaging to identify 12 white matter fiber tracts important for cognitive function, which wer...

Nature versus nurture

Research by UCSB psychologist John Protzko found that environmental interventions can temporarily boost general intelligence in low-birth-weight children. The effects, however, diminish over time, a phenomenon known as the 'fadeout effect'. This suggests that underlying cognitive abilities may not be the primary drivers of intelligence.
