160 Concepts Examples

concept examples and definition, explained below

“Concepts” are mental representations that can refer to a variety of things, from concrete objects to abstract ideas.

Children start to develop concepts from an early age as packets of knowledge, known as mental schema, in our minds. This helps us to learn to create mental categories and differentiate between simple things like ‘dogs’ vs ‘cats’ and ‘tables’ vs ‘chairs’. As we grow older, our concepts or schema become more and more complex.

Below are some categories of concepts, which will help us sort our examples in this article.

  • Concrete Concepts: “dog,” “tree,” “car”
  • Abstract Concepts: “freedom,” “love,” “justice”
  • Artificial Concepts: “triangle,” “square.”
  • Self-Concept: “clever,” “capable,” “incapable”
  • Theoretical Concepts: “gravity,” “electron,” “string theory”.
  • Relational Concepts: “larger than,” “equal to,” “opposite.”
  • Negative Concepts: “injustice,” “abyss”, “unhappy”

Let’s explore some examples from within each category.

In the introduction, I explained how individuals form concepts. This was a fundamental idea emergent from cognitive psychology, and specifically, schema theory.

But we can also see how concepts are shared by all of us.

You read through all the above words and understood what they referred to – that’s because you and I, as English language speakers, share both conceptual understanding and a common way of describing a range of ideas, things, entities, etc.

Our shared agreement about concepts like “freedom” and “love”, and shared words to refer to those concepts, are central to our ability to communicate and form a functioning society.

But, to complicate things further, socially-agreed upon concepts change over time. Perhaps most stark is our changing idea of marriage – from man married to woman exclusively, to any human marrying any other human.

In this sense, many social psychologists and sociologists understand that concepts are socially constructed. And that’s what we’ll talk about next. I’ll see you over on my article: What does ‘Social Construct’ Mean?
