Answer:ingroup; outgroup
Step-by-step explanation:
A collectivist culture as can be seen in Korean cultures is one which is based on needs of the family or community over individual preferences.
Here, People work together for a common goal as they feel connected to each other and group synergy is valued, therefore forming strong bonds which obligates them to be selfless and act like a brother's keeper to each other . Individuals in this culture will definitely more likely help their ingroup( that is the circle of their family, community or group which they belong to) than their out groups (other groups which they do not belong to).
