4045 | Children may have three innate principles which enable them to learn to count |
Full Idea: It has been proposed (on the basis of observations) that young children have three innate principles of counting - one-to-one correspondence of number to item, stable order for numbers, and cardinality (which labels the nth item counted). | |||
From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.60) | |||
A reaction: I like the idea of observed patterns as central (which is the one-to-one principle). But the other two principles are plausible, and show why pure empiricism won't work. |
4044 | Rat behaviour reveals a considerable ability to count |
Full Idea: Rats can determine the number of times they have pressed a lever up to at least twenty-four presses,…and can consistently turn down the fifth tunnel on the left in a maze. | |||
From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.58) | |||
A reaction: This seems to encourage an empirical view of maths (pattern recognition?) rather than a Platonic one. Or numbers are innate in rat brains? |
4048 | Infant brains appear to have inbuilt ontological categories |
Full Idea: Infant behaviour implies inbuilt ontological categories of thing, place, event, path, action, sound, manner, amount and number. ...There is an algebra of relationships between them. | |||
From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.109) | |||
A reaction: Interesting. We would expect the categories in infant brains to have instrumental value, but we don't have to accept them as true. Adults (even Aristotle) are big infants. |
4043 | Elephants can be correctly identified from as few as three primitive shapes |
Full Idea: An elephant may be fully represented by nine primitive shapes ('geons'), but it may require as few as three geons in appropriate relations to be correctly identified. | |||
From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.7) | |||
A reaction: Encouraging the idea of the mind as a maker of maps and models |
4049 | The way in which colour experiences are evoked is physically odd and unpredictable |
Full Idea: A unique yellow experience may be evoked with monochrome light of 580nm, or a mixture of 540nm and 670nm. ..Our interpretation of colour experience is a highly idiosyncratic artefact of our visual system. | |||
From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.117) | |||
A reaction: This confirms what I have always thought - that colour (as qualia) is strictly a feature of minds, not of the world. |
4047 | Gestalt psychology proposes inbuilt proximity, similarity, smoothness and closure principles |
Full Idea: Gestalt psychology claims that there are at least four unlearned factors in perceptual grouping - the principles of proximity (close things), of similarity, of good continuation (extending lines in a smooth course), and closure (which completes figures). | |||
From: Alvin I. Goldman (Phil Applications of Cognitive Science [1993], p.103) | |||
A reaction: This offers a bridge between Hume's associationism and rationalist claims of innate ideas |
