The principle of psychosocial theory
                                                                                Feist , 2008: 252 that “when we enter a situation, we must be able to differentiate
how much we can trust and how much we must mistrust, and I use mistrust in the sense of a readiness for danger and an anticipation of discomfort”. The conflict
between trust and mistrust could create a basic strength called hope if the trust an infant receives is  greater than mistrust. But, if an infant does not receive enough
hope,  he  she  will  experience  withdrawal  the  core  pathology  at  this  stage. Withdrawal will cause an infant to be inferior in facing the world.
2 autonomy vs. shame and doubt.
This  stage occurs in the  age of 2 up to  3  years old.  At this stage,  a child will  experience  autonomy  versus  shame  and  doubt.  Autonomy  is  the  syntonic
element of this stage, while shame and doubt are the dystonic. Similar to the first stage, this stage also needs both autonomy and shame and doubt to be included in
a development. Children who lack of autonomy will found difficulties to develop in  the next  stages. Autonomy develops  from  the basic trust  of children.  Trusting
their surroundings is important in order to create a secure feeling and create self- confidence.  From  the  self-confidence  which  develops  in  a  child,  heshe  will
become  autonomous.  On  the  contrary,  if  heshe  does  not  have  enough  self- confidence, shame and doubt which is a dystonic element will develop. Success in
this  stage  will  lead  to  the  virtue  of  will,  which  is  the  basic  strength  of  early childhood  stage.  In  this  stage,  children  only  achieve  their  basic  will  which  is
imperfect. Their „will‟ would develop through the next stages of life. Those who do not have enough „will‟ might express „compulsion‟.
3 initiative vs. guilt.
This stage occurs in the play age, from 3 up to 5 years old. Erikson 1968 stated that, in addition to identifying with their parents, preschool-age children are
developing locomotion, language skills,  curiosity, imagination,  and the ability to set goals. At this stage a child started to play role on being other people. Play age
is also the stage in which children are developing a conscience and beginning to attach labels such as right and wrong to their behavior.  At this stage children gain
more knowledge and have broader imagination. Due to  their develop  knowledge and  imagination,  they  started  to  show  curiosity  towards  the  world  they  live  in.
They try to  explore the world to fulfill their curiosity. This curiosity will lead to the emergence of initiative. If their initiative is being held back, they will develop
a  sense  of  guilt  on  their  actions  or  initiative.  Too  many  initiatives  could  create problems  to  children.  These  initiatives  could  create  chaos  since  they  act  only
according  to  their  desire  without  concerning  on  the  norms  which  the  society adhered. Both initiative and guilt should equally felt by children. Too many guilt
could also make the child become inferior and restricted. A form of restriction is inhibition which is the antipathy in this stage. The conflict between initiative and
guilt resulted in a basic strength of purpose. At this age, children starting to have their  purpose  in  their  acts,  and  they  creates  their  own  target  in  their  activities  in
order to fulfill their purpose.
4 industry vs. inferiority.
This stage occurs at the school age, from 6 up to 12 or 13 years old. At this
stage,  the  world  which  children  interact  is  broader;  it  includes  family,  peers, teachers, and other adult models. In normal development, children try to read and
write, to hunt and fish, or to learn the skills required by their culture. One of the reasons they did this is because they wanted to get attention and recognition from
their surroundings. According  to  Erikson  in  Thomas,  1985:  241,  children  during  the
elementary school years need and enjoy hours of make-believe games and play, but they become dissatisfied with too much of this and want
to  do  something  worthwhile.  They  want  to  earn  recognition  by producing  something,  to  gain  the  satisfaction  of  completing  work  by
perseverance.
At this stage children start to judge themselves whether they are competent or  incompetent.  If  adults  give  tasks  that  children  have  interest  in  and  could
accomplish,  and  if  adult  give  guidance  to  children  in  accomplishing  their  tasks, children could become industrious. But if children are being disappointed, such as
being labeled as a failure by teachers or adults, they will become inferior. Success in this stage will lead to the virtue of competence. Competence is the confidence
of using physical ability and cognitive to solve the problems occur in school age. Competence becomes the basis for Cooperative participation in adult‟s productive
life Erikson in Feist and Feist, 2008: 256. If the industry and inferiority are not balance,  children  tend  to  give  up  easily  and  spend  more  time  on  unproductive
activity called inertia. Inertia is the core pathology of this stage.
