The Model
Working Memory Cost Metric
After each parse step (Shift, Reduce, Halt):
1 Assign any new Stack entry in the top cell (introduced byShift or Reduce) a cost of 1 multiplied by the number of CCGcategories for the constituent represented (Recency)
2 Increment every Stack cell’s cost by 1 multiplied by thenumber of CCG categories for the constituent represented(Decay)
3 Push the sum of the current costs of each Stack cell onto theCost-record (complexity at each step, sum = tot. Complexity)

Ambiguity & Prosody
The Model
Optimal Ambiguity Resolution
Default Parsing Preference: Prefer Shift over Reduce whenLookahead item can be integrated with cell 1 by Reduce
Predicts preference for more costly late gap analysis (contraGibson, 1998)
This is the optimal strategy if the extrasyntactic informationrequired to override the default action is available at the onsetof the ambiguity
Other things being equal, we expect languages and usage toevolve via linguistic selection for Interpretability using theoptimal strategy

Ambiguity & Prosody
Discussion and Conclusions
Conclusions
1 Trade-off between en/de-coding (grammar) and inference
2 Parallel coding reduces ambiguity without increasingcomplexity or inference (predicting typological facts)
3 Optimal strategy creates linguistic selection for lgs & utts.which are organised to support it
4 On-line overriding of default late gap preference correctlypredicts location of PBs in ambiguous NSRCs
5 Written and spoken usage reflects the predicted costs
6 Are ambiguous medial attachment NSRCs in writing resolvedat onset by lexical, semantic or contextual information?
7 Direct testing of on-line processing of ambig. NSRCswith(out) appropriate PBs
