Social change in psychology refers to the evolution in societal norms, behaviors, cultural values, and social structures over time. This concept is crucial in understanding how societies develop and transform, and how these changes impact individual and group behaviors.

1. Societal Norms and Behaviors: Social change can significantly influence what behaviors are considered acceptable or unacceptable in a society. For example, societal attitudes towards mental health have changed dramatically over the past few decades. It was once stigmatized and misunderstood, but now, there's a growing acceptance and understanding of mental health issues.

2. Cultural Values: Social change can also alter cultural values. For instance, the feminist movement has challenged and changed traditional gender roles in many societies, leading to a shift in cultural values regarding gender equality.

3. Social Structures: Changes in social structures, such as the family, education, and government, are also part of social change. For example, the structure of the family has changed in many societies with an increase in single-parent families, cohabitation, and same-sex marriages.

4. Impact on Individual and Group Behaviors: Social change can influence individual and group behaviors. For instance, the civil rights movement in the United States led to significant social change, altering individual and group behaviors and attitudes towards race.

In conclusion, social change in psychology is a broad concept that encompasses changes in societal norms, behaviors, cultural values, and social structures. These changes can significantly impact individual and group behaviors, shaping the way societies function and evolve.
