Em um grande departamento da universidade, 4 servidores
trabalham 6 horas por dia para suprir as demandas desse
setor. Avalia-se a junção de dois departamentos bastante
semelhantes, estimando-se que a quantidade de demandas
deve dobrar. Supondo que isso de fato ocorra e também a
proporcionalidade dessas variáveis, assumindo que todos os
funcionários passem a trabalhar 8 horas por dia, quantos
servidores precisariam ser alocados nesse novo setor com
essa junção?

How do we measure attention?
Attention, broadly defined, is the ability to direct the
mind on a specific task, says Gloria Mark, author of Attention
Span: A Groundbreaking Way to Restore Balance, Happiness
and Productivity. There are two main types of attention, Mark
explains. Involuntary attention is automatic—it’s what allows us
to react to a loud noise or a jarringly bright light. Focalized
attention, by contrast, is the ability to concentrate on a specific
task. This latter type is what scientists measure when
researching attention spans.
Since the early 2000s, Mark has tracked focalized
attention by observing how long people remain on a task
before switching to something else—such as checking email
or opening a new browser tab. At first, Mark used in-person
observations— researchers shadowed employees throughout
the office. In recent years, she has tracked attention spans
using software that monitors people’s computers.
“Data from our first study, in 2003, revealed that people
spent an average of 2.5 minutes on something before turning
their attention to a different task,” she says, “Our most recent
study done over the past five years shows that the figure has
gone down to 40 seconds.” The measure doesn’t capture how
long people can focus under ideal conditions, Mark notes,
meaning shorter attention spans don’t reflect a permanent loss
of attention capacity, but changes in how often people break
their focus in daily life.
