speech perception.

How do we call the aspects of speech besides the meaning of the words, like intonation, speed, rhythm?

prosody.

Discover Study Smart

What phenomenons fall under the invariance problem?

  • physical differences between the same phonemes in different words
  • differences between speakers (accent, gender)
  • differences within speakers (being sick, emotion)
  • co-articulation.

How do we call the tendency for a speech sound to be influenced by sounds preceding or following it?

co-articulation.

Describe the research by Liberman on artificial speech sounds.

  • phonemes were produced artificially
  • the stimuli was a series of phonemes which would gradually transition into eachother over a sequence of phonemes
  • like ba goes from da to ga
  • participants task was to indicate what they heard at each phoneme.

Describe the results of the research by Liberman on artificial speech sounds.

  • you would expect that participants would indicate that they heard a mixture between two phonemes.
  • this was not the case, participants would say they heard either ba, da or ga. no mixtures
  • shows that we have a categorical perception for sounds,
  • we hear a sound, categorize it, and thats how we indicate what we hear.
  • also at changing points there were frequency's on what people would say they heard.
  • they didn't all give the same answers for which phoneme they heard at each part of the trial.
  • shows that we have trouble distinguishing phonemes that sound alike.

How do we call the principle that refers to detection of distinct words in what is a continuous string of speech sounds?

the segmentation problem.

What is described here; researchers recorded participants speaking and cut out individual words, they later played the individual words to participants in order to have them recognize them. recognition for individual words was reduced to 35 percent. but in four word segments recognition was improved to 70-100 percent.

the segmentation problem.

How do we call the principle that describes that visual perception can overwrite or support auditory perception of language?

the mcgurk effect.

What can be concluded from the McGurk effect?

  • the auditive process provides input for the manner of articulation (nasal)
  • the visual process provides input for position of the lips (place of articulation)
  • visual information is automatically integrated in the speech perception process.

What are the solutions for the invariance problem?

  • categorical perception
  • use of visual context (McGurk)
  • use of auditive context (rest of the word, sentence, story)
  • top-down processing

Which top-down processes contribute to the restoration of the invariance problem?

  • the phonemic restoration effect
  • the word superiority effect

Which top-down process is described; we can hear a complete sentence as if it is normal, when in fact some parts of the sentence (phonemes) are not detectible. the brain fills these phonemes up because it knows the word.

phonemic restoration

Which top-down process is described; phonemes are more easily detected if they are presented in a word compared to being presented individually.

the word superiority effect.

Which type of letter sound relationships are there?

  • regular, or shallow
  • irregular, or deep

How do we call it when a word is pronounced like it is spelled?

a regular letter-sound relationship.

How do we call it when the pronunciation of a word is not to be detected from the spelling of the word, but rather from the knowledge of the word, give an example.

an irregular letter-sound relationship. gh in ghost vs. tough.

What is a grapheme?

a letter

Which two paths can be derived from the dual route model by Coltheart?

  • the grapheme-phoneme conversion path
  • the mental lexicon path

Which path of the dual route model by Coltheart is described; visual analyzing the written word, then convert different letters to different sounds, and then pronounce the word.

the grapheme-phoneme conversion path.

What does the mental lexicon path of the dual route model by Coltheart look like?

  1. written word
  2. visual analysis
  3. orthographic lexicon
  4. phonological lexicon
  5. phonemes
  6. speech signal/speech

How do we call dyslexia caused by brain injury ?

alexia

Which kinds of alexia are there?

  • surface dyslexia
  • phonological, or deep dyslexia
  • non-semantic reading

How do you remember the different type of alexias?

they are named by what they still can do.

What are the characteristics of surface dyslexia?

  • letter to sound information is still intact (superficial properties of a word)
  • difficulties with reading and meaning of a word
  • wrong pronunciation of irregular word

What can be concluded from the fact that people who suffer from surface dyslexia can't pronounce irregular words anymore?

  • the grapheme phoneme conversion path is intact
  • the mental lexicon path of the dual route model by Coltheart is impaired
  • pronounce words based on spelling, regular rules

What are the characteristics of phonological dyslexia?

  • they can read both regular and irregular words
  • trouble with non words (made up letter combinations)

What are the characteristics of semantic dyslexia?

  • regular, irregular and non words can be read
  • but no comprehension when reading

What has become clear about the dual route model by Coltheart from semantic dyslexia?

there is a third route that goes through the semantic system, which is used to being able to understand the meaning of words.
both paths are intact

How do we call impaired reading ability in combination with normal motivation, intelligence eyesight and social development?

innate dyslexia.

What are the possible causes for innate dyslexia?

  • problem turning words into sounds because of inability to recognize the word itself
  • problem turning word into sounds because of inability to recognize the meaning

With auditory word recognition, how do we call the moment where a word is recognized due to the fact that at this point in time no other words can't possibly fit the already pronounced letters?

the uniqueness point.

How does the cohort model of auditory word recognition work?

  • information is time based, since every letter is pronounced after the other
  • so every letter pronounced gives more information
  • all words that fit the current state of information are active
  • per letter pronounced words that don't fit the until now provided sequence get cut
  • until uniqueness point.
  • first bottom up processing, then top down.

How does the trace model of auditory recognition work?

  1. pronunciation features activate phonemes
  2. phonemes activate words that they're part of, and inhibit words that they're not part of
  3. words inhibit eachother, and phonemes that aren't included in them.
  4. words activate phonemes that they consist of.

How does the trace model explain the phonemic restoration?

words activate phonemes that are a part of them, so if phonemes are left out, they're still activated because of this.

How do we call the concept that describes the language-specific sound groupings that occur in a language, which allows us to separate words in a sentence.

phonotactic constraints

How do we call misperceiving a word or phrase in speech?

a slip of the ear

What is the reason for a right ear advantage for speech sounds compared to non speech sounds?

the left lateralization of language

a lexical decision task.

How do we call it when a single unit in a model represents a particular concept?

a localist representation.

How do we call the process by which we access stored knowledge about words?

lexical access.

How do we call a task in which participants need to name a word while response time is being measured?

a word naming task.

How do we call a task in which participants are presented a sentence with a blank space and a word separate, and they need to verify if the word fits the sentence?

sentence verification task.

How do we call words with the same spelling but more than one meaning?

homographs.

How do we call fast movements of the eye made when reading or scanning an image?

saccades

Describe the second route of the spoken words processing model.
