a theorized set of syntactic linguistic rules that are present across all natural human languages
15
Q
what gene is thought to be involved in language?
A

Child-directed speech (CDS) or infant-directed speech (IDS)
speech that is tailored to a young infant or child
35
Motherese/ parentese
an infant-directed way of speaking that involves sing-song like speech cadences, exaggerated vowel pronunciations and repetition
36
do infants show a preference for types of speech?
they prefer IDS
37
head-turn task
a behavioural task used in infant language testing where babies are conditioned to turn their head when they hear a change in sound
38
Liu et al., 1993 motherese experiment
assessed the abilities of 6-12 month old babies to discriminate between different speech sounds using the head-turn task. Found that the language abilities of infants were positively correlated with their mother’s use of elongated and open vowel sounds, typical of motherese

43
morphemes for apples
apple, s
44
Pollack & Pickett, 1964 context and speech experiment
They found that people could correctly identify the word less than half of the time, but when several words from before or after the target word were included, people were better at identifying the word. Demonstrates that context plays an important role in speech perception
45
phonemic restoration effect
a perceptual phenomenon in which sound that is missing or obscured is still perceived if it is highly predictable
46
who discovered the phonemic restoration effect?
Warren, 1970
47
what type of processing is phonemic restoration effect based on?
top-down
48
Warren, 1970 phonemic restoration effect experiment
played participants a recording with a phoneme covered with a cough. Found that most participants didn’t notice any sounds missing
49
McGurk effect
when we view the visual articulations of one phoneme while hearing the auditory signal consistent with another. Demonstrates that our brain uses additional info besides the speech stimulus to determine what phoneme is being said
50
main challenge to speech segmentation
The fact that we do not pause between words
51
Saffran et al., 1996 artificial language and preferences experiment
Found that babies showed a clear bias towards nonwords and that they encoded the frequency with which different sounds appear together, allowing them to identify words
52
lexical processing
determining the meaning of individual words
53
homophones
words that are pronounced identically but have different meanings
54
homographs
words that are spelt identically but have different meanings
55
why do we prefer commonly used words?
because they are processed quicker
56
context is important for
disambiguation
57
Lexical decision task (LDT)
a psychological task in which a participant makes a quick decision about whether a given string of letters is a legitimate word or not
58
Scarborough et al., 1977 commonly used words experiment
used the LDT and found that people were faster at recognizing strings as real words when those words were more common
59
Swinney, 1979 LDT and homophones experiment
Had participants perform a LDT while listening to one of the versions of the homophone and found that participants’ response times were faster in the LDT when related words were presented together.
60
are both meanings of the homophones activated?
both meanings are briefly activated despite the surrounding context favouring one meaning
61
parsing
breaking up languaging into its constituent parts

63
clause
a group of words that express a full idea of someone or something
64
subject
someone or something
65
predicate
the verb
66
syntax-first approach
a theory of language parsing that holds that the parsing of a sentence is first derived based on principles of grammar alone without regard to the meaning of the words, except to determine which grammatical category they belong to
67
late closure
a tendency when parsing to attach incoming words to the current phrase
68
Trueswell et al.,1994 eye tracking and prosody experiment
presented participants with sentences that contained parsing ambiguity and tracked their eye movements to see whether they had to go back and reanalyze each sentence. Found that the meaning of words affected parsing.
69
Tanenhaus et al., 1995 visual input and parsing expeirment
presented participants with sentences that contained parsing ambiguities, and tracked their eye movement while also showing them visual stimuli. Found that the visual information affected parsing behaviour.
70
prosody
the patterns of stress and intonation (pitch) of the speaker, which can convey critical information
71
punctuation and prosody
Punctuation can be seen as a limited version of prosody
72

75
backward inference
a kind of inference in discourse processing in which previous information is needed in order to process current information
76
elaborative experiment
a kind of inference in discourse processing in which the inferred information is not necessary in order to properly understand the text
77
when are participants more likely to report information as novel?
if it was consistent with their expectations
78
when do people engage in inferential reasoning?
at the single-word level as they are reading
79
instrumental inference
a form of elaborative inference in discourse processing in which the tool or instrument that is typically used to perform the task is inferred from the task
80
who discovered instrumental inferences
Singer, 1979
81
when do people engage in online elaborative inferences?
if they have enough context
82
example of the importance of context in inferences
participants understood a text much better when they were told it was about doing laundry because it allowed them to relate the text to their prior experiences
83
Neurolinguistics
a branch of linguistics concerned with the relationship between linguistic behaviour and the structures of the brain
84
Wernicke's area
- critical for language comprehension
- Located in the temporal lobe
- The first region of the cortex to receive auditory information after the thalamus
85
Broca's area
- critical for language production
- Located in the frontal lobe
86
recent studies have provided evidence that language comprehension really involves___
a broader portion of the temporal lobe
87
Broca's area is also involved in ___
language comprehension, particularly the presence of complex sentences
88
are other areas involved in speech production?
Broca’s area might not be the only factor in speech production
89
Arcuate fasciculus
a band of fibres in the brain that connects Broca’s and Wernicke’s areas
90
Arcuate fasciculus in other species
Is absent in many primates, suggesting it might be involved in humans’ unique language capacities
91
hemisphere specialization and language processing
Language production depends heavily on the left hemisphere but the right hemisphere is involved as well, especially in discourse processing
92
patients with right-hemisphere damage
have language deficits. They speak the same number of words, but their speech is less informative and coherent
93
Beeman et al., 2000 hemisphere specialization and naming task experiment
Found a reduced naming time for the left visual field, suggesting that the right hemisphere might be involved in elaborate processing
94
recent studies found pronounced activation in what area during comprehension tasks?
right temporal lobe
95
Linguistic relativity
the theoretical perspective that the language someone speaks affects other areas of cognition
96
who is linguistic relativity attributed to?
Edward Sapir & Benjamin Lee Whorf
97
Whorf linguistic relativity studies
studied Indigenous languages and found that they had many words for snow and thus perceived it differently. However, they didn’t have words for units of day and this influenced their behaviour. These studies are largely discredited
98
Linguistic universalists
the theoretical perspective that the language someone speaks doesn’t affect other areas of cognition
99
Winawer et al., 2007 linguistic relativity study
had Russian speakers (who have two distinct names for blue) perform a colour-matching task and found that they performed the task 10% faster when the non matching patch was in a different colour category than the matching patch compared to when they were both in the same colour category. This didn’t hold for English speakers.

109
morphology & number of language speakers
Morphology (complexity) decreases with languages spoken by more people
110
lexical tones and climate
Lexical tones (tonal languages) are partly determined by climate. Tonal languages are less prominent in dry climates because dry air makes it harder to have the vocal control to produce tonal sounds
111
language and gender inequality
Countries with gendered languages experience higher gender inequality
112
women vs. men's use of language
Women use more adjectives and first-person plurals than men (we need to hurry) and use a reverse accent more than men (end statements like questions)

abstracted entity that supports language
137
types of support for the innateness hypothesis
- convergence
- uniformity
- poverty of the stimulus agent
138
convergence
children are exposed to different learning situations, yet convergence on the same grammar
139
uniformity
children have a similar language-learning trajectory
140
poverty of the stimulus agent
the linguistic environment of a child is not sufficient enough to allow that child to learn a language via reinforcement, rules or imitation.
141
cons of the poverty of the stimulus agent
- Can’t address the following questions:
1. What information is innate?
2. How can you disprove this argument?
3. How do you provide a complete account of all the linguistic data available to a child?
- Adult reformulations of children’ speech target the structure but not meaning
142
long-term effects of parentese
The better infants are at distinguishing the phonetic units, through parentese, the better complex language skills they have years later

Laurel vs. Yanny is an example of
phonological ambiguity
150
how is lexical ambiguity resolved?
context
151
cross-modal priming task

166
L1
first (native) language
167
L2
second language
168
how many people in the world are bilingual?
Estimates range from 50-70%
169
% of English-French bilinguals in Canada vs. Quebec vs. Montreal
- 18% of people in Canada are English-French bilinguals
- 46% of people in Quebec are English-French bilinguals
- 70% of people in Montreal are English-French bilinguals
170
bilingualism in the U.S.
- 22% of Americans speak a language other than English at home
- Spanish is the most common second language
- Bilingualism has almost doubled since 1980
171
the traditional view of psycholinguistics
- Most research on language and cognition examined only speakers of a single language (typically English)
- Monolinguals were the model subjects of the study
- Only the native language could provide an ideal basis for understanding the nature of the language system
172
bilinguals on the traditional view of psycholinguistics
On this view, bilinguals have been considered a special group of language users
173
accented speech and L2 learners
The older individuals were when first exposed to the L2, the more accented their speech is perceived to be
174
grammaticality and L2 learners
Individuals’ ability to correctly judge the grammaticality of sentences decreases with the age they were exposed to the second language
175
new attitude about bilingualism
- Language learning occurs at all ages and language processes are dynamic
- Bilingualism provides a lens for examining aspects of cognition that are being obscured by studying monolinguals alone
176
3 key discoveries about bilingualism
1. Bilinguals are not two monolinguals in one. Both languages are active and competing
2. The bilingual’s language system is permeable in both directions. Critically, the L1 changes in response to learning and using an L2
3. Not all bilinguals are the same. Bilinguals differ by virtue of where they live and the demands that are placed on them to use each language
177
parallel activation
Both languages are active regardless of the requirement to use one language alone: in reading, listening, or planning speech
178
evidence for parallel activation
Many studies have demonstrated that bilinguals recognize cognates (the same word in both languages with the same meaning) more quickly but homographs (the same word in both languages but different meanings) more slowly than control words. Monolinguals do not show these effects.
179
picture naming task
Naming images out loud
180
findings of picture naming task
Found cognate facilitation effects, demonstrating that lexical information is activated in the target and non-target languages
181
Libben & Titone, 2009 study method
tracked French-English bilinguals’ eye movements during reading.
182
fixation
length of the first time the eye fixates on the target
183
how is fixation represented?
by the size of the dot
184
what words elicit more fixation?
more difficult words
185
saccade
the transition between words
186
how are saccades represented?
the lines
187
regression
going back to revise something previously fixated on
188
total fixation duration
length of all eye fixations on a target
189
Libben & Titone, 2009 findings
- In the early stages of comprehension, there is parallel activation regardless of sentence constraint (two languages are active)
- In the late stages of comprehension, parallel activation is resolved for contexts that provide a high semantic constraint (two languages are no longer active)
190
Semantic Relatedness Task
Clapping if two words are semantically related (related in meaning)
191
Morford et al., 2011 ASL semantic relatedness findings
found that bilinguals are faster to judge English when the ASL converges and slower when it conflicts. Monolinguals don’t show these effects
192
Lexical Decision Task
Clapping if you see a word in x language
193
Bice & Kroll, 2015 study aims
examined the cognate effects in monolinguals and L2 learners of Spanish.
194
event-related potentials
voltage fluctuations that are time-locked to an event
195
Bice & Kroll, 2015 findings
- Behaviourally, there was no cognate effect for either group
- ERPs show that the native language is affected by the second language (Reduced N400 for cognates)
196
verbal fluency task
Say as many words that fit into a category as you can in 30 seconds
197
Linick et al., 2009 context and L2 learning
compared to classroom learners, immersed learners produced fewer L1 exemplars. The L1 is suppressed while living in an L2 context
198
Dussias & Sagarra, 2007 L2 and context
the influence of L2 on L1 is not limited to words. It’s also about grammar
199
bilingual experience is characterized by:
- Predominant language
- Habits of language use
- Contextual linguistics diversity
200
linguistic diversity of montreal
mixed French and English
201
linguistic diversity of ottawa
French on one side of the river and English on the other
202
linguistic diversity of Toronto
English with various pockets of other languages
203
French-English bilinguals who report greater linguistic diversity:
- Show a higher reliance on contextual clues
- Exhibit higher connectivity between regions implicated in monitoring such as the anterior cingulate cortex and the putamen

what brain regions are involved in monitoring?
the anterior cingulate cortex and the putamen
205

207
Beatty-Martinez & Dussias, 2017 study method
measured ERPs for bilingual speakers who use unilingual and codeswitched sentences
208
Beatty-Martinez & Dussias, 2017 study findings
Non-code switchers process the cost regardless of the type of code switch
For code switchers, only rare code switches elicit processing costs
209
processing costs depend on
the nature of the bilingual
210
code switches depend on
distributional regularities. Some switches are more common than others. Larger N400 for rarer code switches, demonstrating that they have more difficulty in processing
211
large N400 represents
difficulty processing
