Sternberg's Triangular Theory of Love
44.9K
We typically love the people with whom we form relationships, but the type of love we have for our family, friends, and lovers differs. Robert Sternberg (1986) proposed that there are three components of love: intimacy, passion, and commitment. These three components form a triangle that defines multiple types of love: this is known as Sternberg’s triangular theory of love. Intimacy is the sharing of details and intimate thoughts and emotions. Passion is the physical attraction—the...

Rectangular and Triangular Pulse Function
1.9K
The unit rectangular pulse function is mathematically represented by a rectangular function centered at the origin with a height of one unit. This function is defined by two parameters: T, which specifies the center location of the pulse along the time axis, and τ, which determines the pulse duration.
For example, consider a rectangular pulse with a 5V amplitude, a 3-second duration, and centered at t=2 seconds. This pulse can be expressed using the rectangular function, written as,

Fixed Action Patterns
17.5K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Fixing Double-strand Breaks
14.3K
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

Growth versus Fixed Mindset
264
Carol Dweck introduced the term mindset to describe individuals' beliefs about their intellectual and personal capabilities. These beliefs significantly influence psychological processes such as motivation, goal-setting, and perseverance, ultimately shaping academic and life outcomes. Individuals generally possess one of two mindsets- a fixed or a growth mindset—each promoting different responses to success, failure, and challenge.Fixed vs. Growth MindsetA fixed mindset assumes that one's...
