Maslow's Theory of Basic Human Needs
3.1K
Maslow's hierarchy is described with the help of a pyramidal shape. The most fundamental needs, physiological needs, are at the bottom of the pyramid.
Physiological needs such as hunger, thirst, sex, physical comfort, and survival are at the bottom of the pyramid. These are the components that are necessary to sustain life. Once the first level of needs has been met, the second level arises.
Safety needs include stability and predictability. Protection and freedom from danger are all a part...

Maslow's Need Hierarchy Theory
1.5K
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...

Need for Self-Esteem
305
The human need for self-esteem has long intrigued psychologists, leading to the development of several theories that explore its evolutionary and functional significance. Among the most influential are the sociometer, hierometer, and terror management theories. Each offers a unique perspective on why people strive for self-worth and how it shapes behavior and social interaction.Sociometer TheoryAccording to sociometer theory, self-esteem functions as an internal gauge of social acceptance. It...

Importance of Need for Affiliation
457
The need for affiliation is a fundamental human motive that drives individuals to form and maintain interpersonal relationships. This universal drive varies in intensity among individuals due to genetic predispositions and life experiences, shaping it into a relatively stable personality trait. Social inclusion enhances emotional well-being by fulfilling the need for affiliation, whereas social exclusion leads to distress, negative emotions, and cognitive impairments.Psychological and Emotional...

Friendship formation is a dynamic process shaped by psychological, cultural, and social factors. Friendships play a crucial role in emotional well-being, social development, and personal identity from childhood to adulthood.Childhood and Early FriendshipsFriendships in childhood often arise due to shared environments, such as school or neighborhood interactions. At this stage, proximity and common interests serve as the primary basis for connection. As children grow, their friendships evolve...

Interpersonal relationships progress through stages, beginning with awareness and moving toward mutuality, where emotional connections deepen. While many relationships remain at moderate levels of mutuality, deeper connections form through self-disclosure, trust, and interdependence.Self-DisclosureSelf-disclosure involves revealing personal information, starting with surface-level details and gradually progressing to more intimate content. As trust grows, individuals feel more comfortable...
