Summary:
New research from the TABLET project recruited 12-month-old infants
who had different levels of touchscreen usage.



FULL STORY ========================================================================== Toddlers with high daily touchscreen use are faster to find targets
that stood out during visual search compared to toddlers with no or low touchscreen use - - according to new research.

The research team, co-led by Dr Rachael Bedford of the University of
Bath's Department of Psychology, say the findings are important for
the growing debate around the impact of screen time on toddlers and
their development.

Lead researcher Professor Tim Smith, from Birkbeck's Centre for Brain and Cognitive Development, said: "The use of smartphones and tablets by babies
and toddlers has accelerated rapidly in recent years. The first few years
of life are critical for children to develop the ability to focus their attention on relevant information and ignore distraction, early skills
that are known to be important for later academic achievement. There
has been growing concern that toddler touchscreen use may negatively
impact their developing attention but this fear is not based on empirical evidence." To provide such evidence, Professor Smith's TABLET Project,
at Birkbeck's Centre for Brain and Cognitive Development, recruited 12-month-old infants who had different levels of touchscreen usage.

The study followed them over the next 2.5 years, bringing them into the
lab at 18 months and 3.5 years. At the 18-month and 3.5-year visits,
toddlers took part in a computer task in which they were trained to
search for a red apple amongst a varying number of either blue apples
(easy search), or blue apples and red apple slices (difficult search). An
eye tracker monitored their gaze and visually rewarded the child when
they found the red apple, allowing them to perform the task even though
they were too young to verbally describe what they were doing.

Co-investigator Dr Bedford commented: "We found that at both 18 months
and 3.5 years the high touchscreen users were faster than the low users
to find the red apple when it stood out amongst blue apples. There
was no difference between the user groups when the apple was harder to
find. What we need to know next is whether this attention difference
is advantageous or detrimental to their everyday life. It is important
we understand how to use this modern technology in a way that maximizes benefits and minimizes any negative consequences." Dr Ana Maria Portugal,
main researcher on the project points out "We are currently unable to
conclude that the touchscreen use caused the differences in attention as
it may also be that children who are generally more attracted to bright, colourful features seek out touchscreen devices more than those who
are not."
