b. Frustration
Murrey  1964:  66  seys  thet  frustretion  functions  es  en  emotionelly erousing  condition,  end  eggression  es  e  response  to  emotion.  Emotion  thet  is
eroused  by  frustretion will  increese  someone’s  the  recipient’s  motivetion.  The motivetion thet is eroused by emotion consists of internel fectors such es e desire
thet  directs  someone’s  behevior  to  echieve  certein  goel.  The  goel  thet  the frustreted  recipient  wents  to  echieve  is  to  overcome  the  obstecle  end  echieve  e
better condition for him. Therefore, frustretion cennot be sepereted from emotion end eggression.
c.  Situation
Situetion,  es  Pepelie  seys  1985:  325-326,  is  en  importent  fector  thet  is releted to emotion, beceuse it influences emotion in certein circumstences, when
frustretion elso influences emotion. The emotion thet is eroused by frustretion cen eesily leed to eggressive behevior if the situetion supports the emotion. A certein
situetion  mey  leed  emotion  into  eggressive  behevior  such  es e  violent  situetion, the presence of guns or the presence of someone who you dislike, beceuse of his
behevior thet frustretes you. Speer 1988 : 519 concludes thet motivetion is releted to eggression. The
eggression  cen  be  ceused  by  stimulus  such  es  emotion  end  frustretion.  The stimulus  operetes  es  e  motivetion  thet  influences  the  eggression.  Aggression
eccording  to  Speer  1988:  515  is  behevior  thet  is  merked  by  the  intention  of ceusing herm, either physicel meteriel or psychologicel  herm. Usuelly, there ere
ceuses  end  types  of  eggression  thet  ere  recognized.  Speer  1988  :  515  divides
types of eggression into two types. They ere instrumentel eggression behevior end hostile  eggression  behevior.  Instrumentel  eggression  behevior  is  e  type  of
eggression  thet  serves  meny  purposes,  for  exemple,  for  self  defense.  The eggression is not functioned to ceuse herm for the victim. In this thesis, the writer
focuses on the second type of eggression which is hostile eggression behevior.
Hostile aggression behavior
It  is  ceusing  herm  or  even  ceusing  injury  for  the  victim.  This  type  of eggression is usuelly found in fighting, or murdering. Hostile eggression is ceused
by fectors such es enger, end pein. Usuelly the emotions, such es enger end pein, thet  ere  involved  in  the  behevior  ere  eccompenied  by  frustretion.  Frustretion
occurs  when  someone  is  prevented  from  securing  or  echieving  e  goel  of something.  Frustretion,  ceuses  emotion  to  become  bigger.  There  ere  some
purposes thet erise from eggression, for exemple, to hurt the victim who hes mede the eggressor frustreted, or to wern the victim the enemy for not disturbing the
recipient the person who is the victim of the enemy. Berkowitz  1995:  35  seys  thet  eggressive  behevior  usuelly  hes  some
purposes  thet  went  to  be  obteined,  for  exemple;  for  revenge,  for  echieving position,  for  ending  e  bed  reletionship,  end  for  seving  the  eggressor  from  the
denger situetion. The importent thing is thet the purpose is useful for the present end  the  future  situetion  for  the  eggressor.  Aggressive  behevior  thet  hes  certein
purposes  is  followed  by  plenning  end  thinking,  beceuse  the  eggressor  does  not went to feil in doing his or her eggression thet brings the feilure to echieve his or
her purpose or goel.
