Cognitive Science in despair ?

Reading
- Beginning reading vs. Fluent reading
- Orthography
- Phonology
- Semantics
3
Dual-route model
4
Main issue at stake
- Are two routes to the Lexicon necessary?
- Beginning reading appears different from fluent
reading - Different words behave differently
5
Some Jargon
- Tasks
- Naming
- Lexical decision
- Proofreading
- Semantic categorisation
- Measurements
- Latencies or response times
- Errors
6
Established effects (?)
- Frequency effect
- RTHouse lt RTTint ErrorHouse lt ErrorTint
- Regularity effect
- RTKus lt RTJus ErrorKuslt ErrorJus
- Word length effect
- RTSOP lt RTSTOPlt RTSTOPT
- Neighbourhood size, concreteness, imageability,
age of acquisition, and so on

Phonology The Daemon
- Homophone pair words with identical
pronunciation and different spelling HARE/HAIR
(in English) WEI and WIJ (in Dutch) - Pseudohomophone PSH legal letter string, when
pronounced sound like a word DYME (in English)
or GIJT (in Dutch) - Pseudoword PSW legal letter string, when
pronounced does not sound like a word DYPE (in
English) or GEIM (in Dutch) - Illegal words illegal letter strings, RTAWS or
BTESE in both English and Dutch
8
It all started with
- DYME is more difficult to reject being a nonword
than DYPE, which is in turn more difficult than
DPYE. - Conclusion Phonology is fundamental to reading
9
Van Orden c.s.
- BREAK, part of a car (BRAZE)
- SUTE, piece of clothing (SOUP)
- ROWS, a flower (ROBS)
- GIJT, een dier (GOOT)
- BLOUW, een kleur (BLAF)

- Lexical Decision
- Semantic Categorisation

Now What?
- Are we still ok being busy puzzle solving?
- Should we consider a new paradigm?
- Have we perhaps not yet reached normal science?
- Or as Jan would like to argue You better give up
on the enterprise entirely, because psychology
will never be a science
