Cognitive Capacity of Two-Month-Old Infants
"Parents
and scientists have long wondered what goes on in a baby’s mind and
what they actually see when they view the world around them. This
research highlights the richness of brain function in the first year of
life."
"Although
at two months, infants’ communication is limited by a lack of language
and fine motor control, their minds were already not only representing
to how things look, but figuring out to which category they belonged."
"This shows that the foundations of visual cognition are already in place
from very early on and much earlier than expected."
Dr. Cliona O'Doherty, Trinity Cusack Lab, Trinity College, London

"This study represents the largest longitudinal study with functional magnetic resonance imaging [fMRI] of awake infants. The rich dataset capturing brain activity opens up a whole new way to measure what babies are thinking at a very early age. It also highlights the potential for neuroimaging and computational models to be used as a diagnostic tool in very young infants.""Babies learn much more quickly than today’s AI models and by studying how they do this, we hope to inspire a new generation of AI models that learn more efficiently, so reducing their economic and environmental costs."Rhodri Cusack, Thomas Mitchel Professor of Cognitive Neuroscience, School of Psychology, Trinity College Institute of Neuroscience
According to a newly published study, babies are able to distinguish between various objects they view at two months of age. Previously, scientists had no idea that such young infants had the mental acuity to make such distinctions. "It really tells us that infants are interacting with the world in a lot more complex of a way than we might imagine. Looking at a two-month-old, we maybe wouldn't think that they're understanding the world to that level", explained Dr. O'Doherty.
Data was studied taken from 130 two-month-old infants who, while awake, underwent brain scans, while viewing images commonly seen in the first year of life from a variety of categories, including trees and animals. Viewing an image such as that of a cat, the babies' brains might 'fire' in such a way that researchers were enabled to record the results. If they observed an inanimate object, the infants' brains would fire differently, indicating the infants' early capacity to differentiate something live from a static object.
The study technique, functional magnetic resonance imaging (fMRI), enabled scientists to closely examine visual function more accurately than could be done in the past. Previous studies tended to draw conclusions from observing how long an infant's gaze would be fixed on an object. It was thought from such observations that infants as young as three to four months could distinguish between live and inanimate categories -- as example, between animals and furniture.

"Until recently, we could not reliably measure how specific areas of the infant brain interpreted visual information. By combining AI and neuroimaging, our study offers a very unique insight, which helps us to understand much more about how babies learn in their first year of life.""The first year is a period of rapid and intricate brain development. This study provides new foundational knowledge which will help guide early-years education, inform clinical support for neurodevelopmental conditions and inspire more biologically-grounded approaches in artificial intelligence."Dr. Anna Truzzi, Queen’s University Belfast
The study results were published in Nature Neuroscience. Such an interpretive advance in assessing the capacity of very young children to begin understanding the world around them will assuredly be of value to doctors and researchers in acknowledging the advanced speed of cognitive development in infancy. The study lead author, Dr. O'Doherty from Trinity College Dublin in Ireland, explained the method of making the experience comfortable for participating babies.
To ensure the babies felt secure and the comfort of feeling snug prevailed as their reaction to pictorial exposure of objects and living creatures tested their differentiation capabilities, the babies were placed reclining on a bean bag. The images, pointed out Dr. O'Doherty "appear really big above them while they're lying down. It's like IMAX for babies".
