PSEB 11th Class Sociology Notes Chapter 4 Social Groups

This PSEB 11th Class Sociology Notes Chapter 4 Social Groups will help you in revision during exams.

PSEB 11th Class Sociology Notes Chapter 4 Social Groups

→ Man is a social animal. He cannot live alone. To fulfill his needs, he needs to depend upon others. So, most of his activities are centered around groups.

→ A social group is an aggregate of two or more persons who interact with each other.

→ But to become a group, this interaction must continue for a longer period of time. This interaction motivates him to relate with the group.

PSEB 11th Class Sociology Notes Chapter 4 Social Groups

→ A social group has many features such as it is a collection of individuals, interactions that take place among members of a group, members are conscious about their membership, they have we-feeling among them, each group has certain rules, etc.

→ There exist many social groups in society, and many Sociologists have classified them on many bases. But the classification given by C.H. Cooley is accepted by most Sociologists.

→ According to Cooley, on the basis of physical closeness and distance, there are two types of groups-Primary groups and Secondary groups.

→ Primary groups are the groups in which members have physical proximity with each other.

→ We meet these members on a daily basis, share everything with them, and love to live with them. For example, family, playgroup, neighbourhood, etc.

→ Secondary groups are exactly opposite to primary groups. In such groups, we can take membership with our will and can leave them at any time.

→ There are no close relations among their members; for example, political parties, trade unions, etc.

→ Secondary groups have many features such as physical proximity, temporary in nature, formal relations, optional membership, etc.

PSEB 11th Class Sociology Notes Chapter 4 Social Groups

→ Primary groups are of great importance as we cannot live without them. They help in the process of socialization and keep control of individual behaviour.

→ Sumner also classified groups and this are-In-group and the Out-group.

→ In-groups are the groups about which an individual is completely conscious. Out-groups are the groups with which an individual does not have we-feeling.

→ Robert Merton gave a new type of group called Reference Group. Sometimes an individual tries to control and direct his behaviour according to a specific group. That group for the individual is a reference group.

→ We-Feeling: The feeling with which we identify ourselves with the group that we are its members.

→ Primary Group: The group with which we are quite close and without which we can’t live.

→ Secondary Group: The group whose membership is taken when the need arises and can be left at any time.

→ According to Aristotle, man is a social animal. He cannot live alone.

→ An individual can neither live out of society nor can he think about it. He needs to depend upon 6thers to fulfill his needs.

→ To fulfill his needs, an individual needs to make relations with others, and the web of social relations is known as society.

→ Different sociologists have divided societies on different bases such as Comte (intellectual development), Morgan (social development), Spencer (the degree of structural complexity), Tonnies (types of social ties), Durkheim (types of solidarity), etc.

→ Society has many features such as it is abstract, it is based on similarities and differences, co-operation and conflict both exist in it and a system of stratification is always there in it.

→ Man has a very close relation with society because he cannot live alone. To live, he needs the help of others.

→ Durkheim was of the view that society is associated with every aspect of our life.

→ Humans are also important for society because, in their absence, there can be no existence of society.

→ When a few individuals live in a group, in a particular geographical area, in an organised manner and spend the whole of their life without any particular motive, it is known as community. We-feeling always exists in the community.

PSEB 11th Class Sociology Notes Chapter 3 Society, Community and Association

→ There are certain elements of the community such as a group of people, definite geographical area, community feeling, common culture, etc.

→ Association is based on co-operation. When a few people come together, co-operate with each other to attain certain objectives and form an organisation, it is called association.

  • French Revolution and Enlightenment Movement
  • Development of Natural Sciences and
  • Industrial Revolution and Urbanisation.

→ Many scholars contributed to the advent of the French Revolution. They challenged the authority of the Church and did not follow the Church’s orders blindly. This encouraged the people to solve their problems in a logical manner.

→ During 16th and 17th Centuries, Natural Sciences made great progress. This progress motivated social thinkers to invent something in the social sector.

→ A new belief came forward that as natural sciences understand the biological world, the same method can be used on social phenomena.

PSEB 11th Class Sociology Notes Chapter 1 Emergence of Sociology

→ Sociologists such as Comte, Spencer, Durkheim tried to understand the social phenomena in the same way and they were quite successful in their effort.

→ In the 18th Century, Industrial Revolution came in Europe, and consequently, industries and urban centres emerged a great deal.

PSEB 11th Class Sociology Notes Chapter 1 Emergence of Sociology

→ According to the synthetic school of Sociology, it is not an independent science because it is a synthesis of other social sciences and takes help from them to create its subject matter. Durkheim, Hobhouse, Sorokin, etc. are the major exponents of this school.

→ Sociology holds a very important place in our daily lives as it studies different institutions, helps in social progress, solves different problems, and forms programmes of social welfare.

→ Individualism: The feeling in which an individual thinks only about himself instead of thinking about society.

→ Capitalism: It is a system of economic enterprise which is based on market exchange. The meaning of Capital is any asset including property, money, and machines, which is used to produce commodities for sale or invested in the market to earn profits.
