Final answer:
Kurt Lewin's work in social psychology focused on group dynamics and organizational psychology, while the Interactionist perspective examines day-to-day interactions within groups. Clark McPhail's Assembling Perspective credits individuals in crowds as rational beings, focusing on collective action.
Step-by-step explanation:
Theoretical Perspectives on Feelings and Group Dynamics
The theory that focused on how people feel and how they work together in groups is rooted primarily in the field of social psychology, and specifically in the work of Kurt Lewin. Lewin is often considered the founder of social psychology, and he conducted extensive research on leadership styles, team structures, and group dynamics. His studies included experiments with children to observe the effects of leadership style on behavior within groups, such as aggression and satisfaction. Lewin's work is pivotal to organizational psychology and laid the foundation for exploring the interplay between individual feelings and group cooperation, competition, and communication.
Another key theory in the realm of how individuals engage in groups is the Interactionist perspective or Symbolic Interaction, which takes a micro-level view and investigates day-to-day interactions within groups. This perspective pays special attention to leadership styles and the dynamics of groups, which is crucial for understanding organizations and collective actions such as the MeToo movement or the Tea Party Movement.
Lastly, the Assembling Perspective developed by Clark McPhail recognizes individuals in crowds as rational beings and focuses on the processes that define crowd behavior. Unlike previous theories that considered crowds as irrational, McPhail's approach emphasizes shared interests and the lifecycle of gatherings in the study of collective action. His perspective is anchored in the rational and instrumental behaviors of individuals engaging in group decision-making.
