when students experienced play performance by themselves and involved in the activity whether as actors, stage manager, or director, they would have stronger
perceptions rather than those who have the perception by listening to someone’s opinion about play performance.
During the process of creating or shaping perception, there are some factors probably influencing someone’s perception. According to Gibson et al
1985: 64, there are six factors influencing someone’s perception. They are stereotyping, selectivity, self-concept, situation, needs, and emotion.
a. Stereotype
The first factor stated by Gibson et al is stereotype. Gibson et al 1985: 64 stated that stereotype is a set of thinking in a particular group that is generalized to
all members of the group. It means that probably the ELESP students year 2007 have already set some knowledge in their mind, though they probably do not
know whether it is true or not. When researcher conducts this research about the ELESP students year 2007’s perceptions on play performance in Sanata Dharma
Univeristy of Yogyakarta, stereotype might occur. Therefore, when they think or consider that Play Performance is good, they will set it in their mind so they will
perceive Play Performance positively, and vice versa.
b. Selectivity
The second factor is selectivity. According Gibson et al 1985: 65, people tend to ignore information or cues that might make them feel discomfort. Since
people tend to select the positive stimuli, it is impossible for people to catch all of stimuli which exist in their environment. It means that only certain stimuli are
chosen or taken, then processed in people’s brain. On the other hand, since people have various interests, they may select what is important in fulfilling their needs.
In Play Performance course, students have their own interest toward Play Performance course and whether this course is important for them or not.
c. Self- Concept
The third factor is self-concept. According to Mouly 1973: 92, people only perceive something that is consistent with their motives or goals, and
interpret our experiences to make them compatible with our present self-concept. It indicates that the way people see themselves in the form of self-concept will
also influence their perceptions on something in their environment. It is also supported by Gibson et al. Gibson et al 1985:67, in their research, state that 1
knowing one self makes it easier to see others accurately, 2 one’s own characteristics affect the characteristics identified in others, and 3 persons who
accept themselves are more likely to see favorable aspects of other people.
d. Situation
