Lecture 10 Flashcards
Huey’s reading experiment
Huey devised an apparatus that contained a cup that was placed on the cornea with a hole drilled into it, which was attached to a mechanism that transferred movement onto a kymograph (an analog device that draws a graphical representation of spatial position over time).
Fixations - length
Between 100-500ms, depending on the difficulty of the test.
Saccades - length
Span about 7-9 characters.
Dual-route model
The ‘route’ we take depends on the words we’re reading.
- Words that occur often follow the left direct lexical route.
- Infrequent or non-existing words take the right phonological route.
A horse race model
Both routes (dual reading route) are parallel but do not cooperate. The first one to finish wins.
Interactive activation model
Activated words provide ‘top-down’ feedback to the reader.
- Used to dispute the Dual Route Model
Surface dyslexia
Impaired direct lexical route.
- Impaired reading of words with “irregular” or exceptional print-to-sound correspondences
Phonological dyslexia
Impaired phonological route
- Inability to read non-words like ‘refki’.
Deep dyslexia
Readers cannot retrieve the meaning of a word, but seem to have access to the semantic representation.
- Instead of ‘chair’ they may read ‘table’.
Developmental dyslexia
The child fails to read adequately despite normal education, intelligence, and an ability to learn.
Linguistic relativity hypothesis
Language indeed may influence the way we think and perceive.
Classical view (concepts (2))
Concepts are sets of rules that specify necessary and sufficient conditions for category membership
- Necessary: must be true in order to belong to the category.
- Sufficient: if true, the object must belong to the category.
Family resemblance theory
Members of a category have certain characteristic features, but not every member needs to possess all these features, and some features are never shared.
Prototype theory (membership)
Categorisation is organised around the properties of the most typical member of that category.
- Membership is ‘graded’; some objects fit the prototype better than others.
Exemplar theory
An object is compared with stored memories of all category members (exemplars) we have encountered.
