This document discusses a study on the relationship between second language acquisition and schizophrenia. The study found that while schizophrenia causes language deficits in patients' first language, many patients do not show these same deficits when using a second language. The research suggests that studying second language performance could provide useful insights for research on second language acquisition and schizophrenia.

1. Second Language Acquisition and Schizophrenia
Schizophrenia is a mental disorder. One of the
many symptoms is the malfunction of the
language capacity of the patients, such as
inventing words or producing nonsensical
speeches. However, it is suggested that many of
the patients don't reveal these linguistic deficits in
a second language performance. Thus, this
research shows the relationship between the
second language acquisition and schizophrenia. It
is hoped to be useful in the second language
acquisition researches.

2. Based on Seliger and Shohamy an empirical knowledge can be
obtained through the process of experimentation and observation
by interacting with natural world. Moreover, this type of knowledge
is characterized by observing a phenomena and drawing
conclusions through experimentation and experience. Thefore, we
arrived at the conclusion that this article is based on empirical
knowledge because it was observed pacients with schizophrenia
and through experiments it was reached a conclusion.

3. According to Seliger and Shohamy there is often interaction between
basic, applied and practical research. They said that applied research
influenced the construction and revision of theories and hypotheses
developed in basic research in order to be “applied”.
For this reason, we can say that this article is applied research because
it was concluded, based on the results, that the pacients have less
troubles learning the second language than the first language. Moreover,
it has a theory behind that supports what they have applied in order to
get the results about second language acquisition and schizophrenia.
