[how psychologists tend to see concepts]

6 ideas
Concepts are rules for combining representations [Kant, by Pinkard]
     Full Idea: For Kant, concepts should be thought of as rules for the combination of representations.
     From: report of Immanuel Kant (Critique of Pure Reason [1781]) by Terry Pinkard - German Philosophy 1760-1860 01
     A reaction: Kant seems to have thought that they are rules we decree for ourselves (like the categorical imperative). So think of private languages, and you get Hegel's much more social view of concepts (I think).
All human cognition is through concepts [Kant]
     Full Idea: The cognition of every, at least human, understanding is a cognition through concepts. ...A concept is a unity of the act of bringing various representations under one common representation.
     From: Immanuel Kant (Critique of Pure Reason [1781], B093/A68)
     A reaction: This puts concepts right at the heart of human understanding, as the building blocks for propositions and beliefs. Do gods and dogs use concepts? If artificial intelligence cannot program concepts, is it defeated? Are there non-conscious concepts? …
By 'concept' psychologists mean various sorts of representation or structure [Machery]
     Full Idea: Psychologists use 'concept' interchangeably with 'mental representation', 'category representation', 'knowledge representation', 'knowledge structure', 'semantic representation', and 'conceptual structures'.
     From: Edouard Machery (Doing Without Concepts [2009], 1.1)
     A reaction: [Machery gives references for each of these] Machery is moving in to attack these, but we look to psychologists to give some sort of account of what a concept might consist of, such that it could be implemented by neurons.
Psychologists treat concepts as long-term knowledge bodies which lead to judgements [Machery]
     Full Idea: In psychology, concepts are characterized as those bodies of knowledge that are stored in long-term memory and used most higher cognitive competences when these processes result in judgements.
     From: Edouard Machery (Doing Without Concepts [2009], Intro)
     A reaction: Machery mounts an attack on this idea. I like the 'mental files' idea, where a concept starts as a label, and then acquires core knowledge, and then further information. The 'concept' is probably no more than a label, and minimal starter information.
Concept theorists examine their knowledge, format, processes, acquisition and location [Machery]
     Full Idea: Psychological theories of concepts try to describe the knowledge stored in concepts, the format of concepts, the cognitive processes that use the concepts, the acquisition of concepts, and the localization of concepts in the brain.
     From: Edouard Machery (Doing Without Concepts [2009], Intro)
     A reaction: I suppose it would the first two that are of central interest. What individuates a concept (its 'format') and what are the contents of a concept. The word 'stored' seems to imply a mental files view.
Psychologist treat concepts as categories [Machery]
     Full Idea: Psychologists often use 'concept' and 'category' interchangeably.
     From: Edouard Machery (Doing Without Concepts [2009], 1.1)
     A reaction: Well they shouldn't. Some concepts are no more than words, and don't categorise anything. Some things may be categorised by a complex set of concepts.
