The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

49.5K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Levels of Organization01:09

Levels of Organization

122.0K
Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:
The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules...

Levels of Communication II: Organizational, Public, and Group Dynamics

2.0K
Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

Maslow's Need Hierarchy Theory01:27

Maslow's Need Hierarchy Theory

157
Abraham Maslow's theory of motivation, introduced in 1943, is widely known as the "Hierarchy of Needs." This theory posits that human needs are arranged in a hierarchical structure, starting with basic survival needs and progressing toward more complex psychological and self-fulfillment desires. The hierarchy is typically a pyramid, and the lower needs must be satisfied to reach the next level.
At the pyramid's base are physiological needs, including food, water, and shelter...

Structural Organization of the Human Body: An Overview

12.9K
It is convenient to consider the body's structures in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms.
To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms, and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of...

Area of Science:

  • Animal Behavior
  • Evolutionary Biology
  • Social Systems

Background:

  • Multi-level societies feature nested social units, allowing cooperation beyond core groups.
  • Individuals engage with higher-level partners for specific tasks or merge units for benefits.
  • Understanding the evolution of multi-level sociality requires data on fitness consequences of cooperation at various social levels.

Purpose of the Study:

  • To investigate the fitness benefits of cooperation within multi-level societies.
  • To explore the convergence of cooperative tasks across different social levels in diverse taxa.
  • To highlight the adaptive role of multi-level sociality in environmental buffering.

Main Methods:

  • Review and synthesis of existing data on multi-level social systems.
  • Comparative analysis of cooperative behaviors and their fitness outcomes across species.
  • Examination of species examples, including dolphins and fairy-wrens.

Main Results:

  • Cooperation with higher social levels is predicted to increase individual fitness.
  • Similar cooperative tasks are observed across different social levels in documented multi-level societies.
  • Multi-level sociality facilitates flexible associations to cope with environmental fluctuations.

Conclusions:

  • Further data accumulation will clarify task convergence in diverse multi-level social organizations.
  • Multi-level sociality is a key evolutionary strategy for enhancing fitness and adaptability.
  • Division of labor within multi-level societies drives social evolution.
