The interactive

activation (IA) framework is again useful. Here, the sublexical units represent graphemes
rather than phonemes.
Frequency
effect is explained in the same way as in TRACE
Lexical status effect
is where lexical decision times to words are shorter than those to nonwords. A
nonword response is made when no lexical unit reaches threshold (in the IA model), so the delay comes
about because the reader is waiting for a deadline (a time criterion) beyond which it is accepted that no
lexical unit is going to be activated to threshold. The wordlikeness of the nonword will determine what
the deadline is
-
the more wordlike the nonword, the more activation there will be amongst the lexical
units, and therefore the longer it is worth waiting to establish if a unit is going to reach threshold.
The above describes the Orthographic processing system but it is it possible that the phonological
processing system is involved when reading silently for meaning?
Before learning to read, one can access semantics (S) via a phonological system (P).

Document Summary
Here, the sublexical units represent graphemes rather than phonemes. Frequency effect is explained in the same way as in trace. Lexical status effect is where lexical decision times to words are shorter than those to nonwords. Before learning to read, one can access semantics (s) via a phonological system (p). Two ways of getting from print to sound (in an alphabetical script) according to the dual-route model of. Sublexical route using grapheme-phoneme conversion (gpc) rules = pre-lexical or. Won"t work for irregular words (e. g. , choir or pint), but allows novel words (i. e. , nonwords) to be pronounced. Lexical route using whole word information = addressed route. The phonics approach to the teaching of reading emphasises the importance of the sublexical route in reading acquisition, while the whole-word approach assumes that the lexical route is important. Support for the dual route model comes from the regularity effect in naming (e. g. , irregular word pint takes longer to name than the regular word coin).
