Contemporary Study: Sebastian and
Hernandez-Gil (2012)
- Generalisability
- The sample was large with mixed
genders, and came from a mixture of
different schools in Madrid. This
increases the generalisability of the
results amongst Spanish 5-17 year
olds as it is representative of this
population.
- HOWEVER, they made sure to control the
sample so that there were no participants
with any impairments, which limits the
results as it cannot be generalised to those
with impairments.
- 570x participants were used. They
were all native spanish speakers, from
a mixture of schools, and had no
impairments that may skew results.
- HOWEVER, they made sure to control the
sample so that there were no participants
with any impairments, which limits the
results as it cannot be generalised to those
with impairments.
- The study was only conducted in
Madrid, Spain, limiting results to this
are and cannot be generalised
beyond that.

- Reliability
- The study was well controlled which
makes it replicable. This increases the
reliability of the results as the study
could be carried out again to look for
similar results.
- Participants were split into 5 different
age groups. A pilot study was
conducted, and then every participant
was asked to recall a digit string which
was read out to them at the same rate
for everyone. They then were asked to
recall the digits in the correct order. If
this was done correctly, another digit
was added on. The digit span recorded
was the longest digit string they could
recall without error, and the average
score was recorded for each age group.

- The study has been
replicated in multiple
different cultures which
allows results to be
compared, and increases
the reliability of the
results.

- Application
- Results could be applied to the
education system in order to make
improvements, for example, the age at
which important exams are taken -
test children when their memory is
fully developed, as they do in the UK
(fully developed at 15, which is around
the time GCSEs take place).
- Aimed to look at the development
of the phonological loop in spanish
5-17 year olds.
- Results showed that the mean recall
score increased as age increased,
until improvements slowed at around
11. Memory was found to be fully
developed in Spanish children by 17.

- Validity
- The results may reflect low task
validity, as the task participants were
asked to carry out does not reflect how
we recall and remember things in real
life situations.
- There is high ecological validity. This is because
the study was conducted in a natural
environments for the participant (at their
schools). This would reduce the possibility of
demand characteristics occurring and affecting
results, so results are more likely to reflect
their natural behaviour.

life situations.
