L1 Language, Visual World Recognition Flashcards
What was Dufau 2015 Event Related Potentials megastudy ?
Measure electrical activity using electrodes
960 words and 140 pseudo words shown to 75 ps
Lexical decision making task
What is the visual word recognition like in literate adults ?
Fast and automatic - 250-300 words per min, mandatory, 200ms to distinguish between words and non words
Flexible - can read different scripts and fonts
Precise - able to distinguish similar words
What is typical vs lexical decisions ?
Typical words vs atypical words - letter combination e.g. lint vs kiwi
Lexical words vs pseudo words - real words or not
What is the stroop test 1935 ?
No difference between reading words in incompatible colours vs reading words in black
Slower response for ink colour od incompatible words
What was Bisson 2012 research results when reading subtitles ?
Dutch audio, no subtitles - focused on the main characters
Dutch audio, English subtitles - focused on the subtitles
Dutch audio, Dutch subtitles - focus on both characters and subtitles
English audio, Dutch subtitles - focused on characters, glimpsed at subtitles
Everyone kept trying to read over watch
What is masked priming ?
Presented two words in succession
Priming word is presented briefly
Task focuses on the target word
Masked priming paradigm - mask, prime, target
Record time taken to identify if the masked word was real or not
Happens unconsciously
What are the results of masked priming and relatedness ?
A masked orthographically related nonword prime, speeds up target word processing
compared to orthographically unrelated prime (Forster 1987)
What was Perfetti and Tan research ?
They did priming in chinese
They found that phonological and semantically related words facilitated priming effect
What effect did Rawlinson 1999 demonstrate ?
The letters inside a word can be jumbled up and we still understand it because humans don’t read every letter they will read the first and last letter mainly
What did Perea 2015 find out about case alteration ?
Masked priming lexical decision task with words in alternate cases and did not find considerably dramatic differences between lower case and alternate cases
What did Grainger find about orthographic in animals ?
Baboons can be trained to see English words vs nonwords
What is orthographic input coding ?
Invariant letter and word recognition a = A /= b
Distinguish between similar words by position specific coding
Order is important
What is position specific letter coding ?
Implemented in a computer programme
Interactive activation model (McClelland and Rumelhart 1981)
Dual Route Cascade model (Coltheart et al, 2001)
Multiple Read out model (Grainger and Jacobs, 1996)
What is the Interactive Activation model ?
Localist connectionist model / neural network model
Includes visual features, letters and words
Visual features will support a letter resulting in inhibition or excitation
What are the layers to the IA model ?
Word level - word nodes inhibit all other nodes (lateral inhibition)
Letter and feature levels - 4 pools of representations
Resting level activations of words vary between -0.5 and 0
Activation of each node varies between -0.2 and 1
