McCloskey

1. McCloskey - The dissociation logic is to narrow accumulate the neuropsychological field, and is based on two mistaken suppositions: • The data obtained from cognitive deficit research is crude, and limited to level of performance measures (percent correct) on a small number of tasks. • The interpretation of the results is a fixed procedure limited to the dissociation logic. Thus withholding other empirical and theoretical considerations.

2. Examples for a more broadly conceived cognitive neuropsychology • Spelling studies of dysgraphic patients • Patient HE: Shell –Sheel Needle- Neddle • Patient LB: Pezzo- Zeppo Blocco – Bcollo • Interpretation: a single letter representation for doubling a certain letter in the orthographic representation: Shel Shel d d

3. Example of an argument against the dissociation logic as irrelevant • Picture naming study • Patient PW: Spoken: turtle; written: owl • Single dissociation: against the phonological mediation hypothesis (semantics phonology orthography). • Interpretation: orthographic autonomy hypothesis (semantics orthography) .

4. Example of an argument against the dissociation logic as irrelevant • The resource artifact argument (spoken restoration of phonological information is more demanding then the written one)- not plausible. • The double dissociation logic (a subject correct in spoken naming and incorrect in written naming) support both of the hypothesis. • Conclusion: When the dissociation logic interpretation is not applied, the arguments against it are beside the point. חזרה לראשי
