Chapyer 7: Cognition

Cognition: The mental activities associated with thought, decision making, language, and other higher mental processes. Basic Element of Thought: Concepts, Propositions, Images
A) Concepts:
1- Concrete concept: Concrete is something that can be seen or known. 2- Abstract concepts (logical & Natural): A concept that you can not always see or touch. Logical concepts: Concepts that can be clearly defined by a set of rules or properties. Ex: A Triangle can be defined if it only have three sides whose angles add up to 180 degree. Natural Concepts: Concepts that are not based on a precise set of attributes or properties, do not have clear-cut boundaries, and are often defined by prototype. Ex: For fruit, most people think of apple, peaches, or pears, they are far less likely to mention avocados. B) Propositions: Sentences that relate one concept to another and can stand as separate assertions. Ex: Sun rise from east. Salt melt in water. * Dogs chase cats (relationship between two concepts)

* Birds have wings ( individual's concept)

C) Visual Images: Mental pictures or representations of objects or events.

Heuristics: Mental rules of thumb that permit us to make decisions and judgments in a rapid and efficient manner. Availability Heuristic: A cognitive rule of thumb in which the importance or probability of various events is judged on the basis of how readily they come to mind.
