CHAPTER II REVIEW OF RELATED LITERATURE
This  chapter  includes  two  parts,  namely  theoretical  description  and theoretical  framework.  The  theoretical  description  presents  some  important
concepts  which  are  related  to  the  research.  The  concepts  are:  1  perception,  2 speaking,  and  3  scripted  role  plays.  Moreover,  the  theoretical  framework
consists  of  summary  from  the  theories  that  will  be  used  to  solve  the  research problems.
A. Theoretical Description
In  this  section,  the  researcher  discusses  the  theories  which  are  related  to this  study.  There  are  three  major  theories  need  to  be  explained.  They  are
perception, speaking, and scripted role plays. Before going to explain the theories, the researcher wants to review the previous research that inspires the researcher to
do this research in this study. Th
ere  are  so  many  researchers  who  conduct  the  research  on  students’ perception.
They  are  students’  perception  on  the  writing  skill,  reading  skill, listening  skill,  speaking  skill,  and  some  integrated  skills.  Especially  for  the
speaking  skill,  there  are  some researchers  who  wrote  students’  perception  to
enhance speaking skill  but  only some researchers focus  on writing the topic role play as the major point to research. Therefore, the researcher in this study wants to
conduct the research of the students’ perception on the use of a scripted role play
10 in  this  study.  The  scripted  role  play  is  used  by  the  researcher  because  in  the
previous research, it has not used yet. In the next session, the researcher wants to explain  the  perception  since  the  major  study  of  thi
s  research  is  the  students’ perception.
1. Perception
This part provides the theories related to the perception.
a. The Nature of Perception
There are some understandings of perception from the experts. According to  Worchel  and  Shebilske  1998,  perception  is  the  process  of  interpreting
information.  Moskowitz  and  Orgel  1969  argue  that  perception  is  a  global response  to  a  stimulus  or  a  set  of  stimuli.  Besides,  Szilagyi  and  Wallace  1980
define  perception  as  a  process  by  which  individuals  attend  to  incoming  stimuli, organize,  and  then  interpret  such  stimuli  into  a  message  that  in  turn  indicate  an
appropriate action or behavior. Therefore a perception is about giving the stimulus and response as the information.
Not every person has the same perception even though they have the same object. It is because people have their own experience in the past.  Mouly 1973
says  that  two  persons  looking  at  the  same  phenomenon  may  see  very  different things.  Wick  and  Pick  1978  also  state  that  there  is  a  connection  between
perception and experience. In this study, the perception refers to the response of a scripted  role  play.  T
he  students’  perception  on  the  use  of  a  scripted  role  play would be stronger if they experience it. If the students have a positive experience
they would form a positive perception and if the students have a negative or bad
