Week 7 Rapp Reading Flashcards
According to Rapp (1995), how is lexical information regarding the meaning, phonology, orthography and syntax of lexical items stored?
In components and with internally complex representations.
What could be described as a ‘tip of the tongue’ disorder?
Anomia - can describe the function of the word, but cannot come up with the phonological name, meaning available but names are not.
Talk about spared knowledge of meaning
Can correctly define items, but not name them or spell them, not associated with articulation or writing deficits.
Talk about spared knowledge of forms
Patients who can read or write words they cannot comprehend, case of J.J. could read 75% of words he did not know the meaning for, damage has impacted meaning, but not form, “my french”, also another patient could identify words from wordlike forms (98%) and judge whether 2 words were synonyms for each other
According to Rapp, are the representations for meanings and forms functionally, anatomically and physiologically separate?
Yes!
According to Rapp, are the representations of auditory and visual words stored differently?
Yes, subjects have made different responses in different modalities, e.g. presented with a skirt, says sock but writes skirt.
Explain some of the problems with the theory that category specific deficits in meaning are due to inanimate objects featuring identify by function whereas animate objects identify by visual feature.
within category impairments such as being specifically deficit in identifying fruit and veges, but not other foods. Hypo - fruit and vege are id’d by colour? Wrong! No colour deficits, difficulties with tactic identification as well. Hypo - shared features of fruit and vege could involve relations to plants, or function as food, items that also use such features should be affected - plausable, but investigations lacking.
Talk about category specific deficits in form
patients have been found that display deficits in naming verbs but not nouns in the written form only, whereas others have deficits in verbs but not nouns in the spoken form only
Discuss some problems in investigating the manipulation or otherwise of morpheme sized units of meaning and/or form
Those who make what would be described as morphological errors (e.g. talking > talked) frequently display semantic errors (flute > piano) or phonological ones (sank > sand). Difficult to specifically attribute to errors in morphological manipulation. Hypo, errors at level of retrieval of spoken forms, miscombination of morpheme units. Produces errors not occurring in language.
