2. NEUROBIOLOGICAL CONSIDERATIONS
Hemispheric
lateralization
• As the human brain matures, certain functions are assigned, or
"lateralized," to the left hemisphere of the brain, and certain other
functions to the right hemisphere
• Language functions are assigned to the left hemisphere
Biological
Timetables
• As all animals growing process, humans too have a period in which a
human being acquire his identity and it is related according all the
aspects that surround them, one part of identity is language and once
first language is acquire brain doesn’t need other language, that is why
native language is always first, not second.
Right-
hemispheric
participation
s
• Right hemisphere works to give brain some strategies to acquire
language after brain lateralization process
3. COGNITIVE CONSIDERATIONS
Sensorimot

two)
Preoperatio

seven)

sixteen)
Concrete
operational

eleven)
Formal

stage (ages
eleven to
sixteen)
The dominance of the left hemisphere occurred when a child matures
contributes to a tendency to over-analyze and be too intellectual
focused on the task of learning a second language
4. AFFECTIVE CONSIDERATIONS
Humans are emotional
creatures, and express
our feelings is an
important part of our
nature.
Children has less inhibitions
than adults, that is why they
are nor afraid to make
mistakes learning a language.
Ego-language is a theory in
which the brain understands
that the new language and
attacks his identity is
established and why learning
a second language is no
longer achieved as native.
Bad attitudes influence in
language learning too, if we
have a preconceived idea
about certain language or
people, we would not learn
well.
Peers pressure is when we
fell press by other people to
speak in a certain way, and
uses specific words, It
generate unconformity in
learning.
5. LINGUISTIC CONSIDERATIONS
Bilingualism
The acquisition of two languages in
bilingual children is slightly slower than
normal for the first language acquisition
time. But bilingualism children have more
learning techniques than monolingual
children
Interference between first
second languages
Linguistic and cognitive processes
of learning a second language in
young children are presents in the
processes used on first language
Interference in adults
They also use their knowledge of
grammatical rules of first language to
help them to express themselves in
second language, the first language,
however, can be used more easily to fill
the gaps that the adult student cannot fill
the generalization in the second
language.
