language

What is the hierarchical organisation of language?

Language is hierarchically organised into smaller units that combine to form larger meaningful structures (e.g., phonemes combine into words, words into sentences).

What is phonology?

Phonology is the study of speech sounds and how they function within a language.

What is a phoneme?

A phoneme is the smallest sound difference that changes meaning in a language.

Give an example of a phoneme difference.

Changing “bat” to “pat” changes meaning because /b/ and /p/ are different phonemes.

What are the three major ways phonemes differ?

Place of articulation, manner of articulation, and voicing.

What is place of articulation?

Place of articulation refers to where in the vocal tract a speech sound is produced.

What is a bilabial sound?

A bilabial sound is produced using both lips together.

Give examples of bilabial sounds.

/p/ and /b/.

What is a labiodental sound?

A labiodental sound is produced with the lip against the teeth.

Give examples of labiodental sounds.

/f/ and /v/.

What is an alveolar sound?

An alveolar sound is produced with the tongue just behind the upper teeth.

Give examples of alveolar sounds.

/t/ and /d/.

What is voicing in speech production?

Voicing refers to whether the vocal cords vibrate during sound production.

How can you test whether a sound is voiced?

Place your hand on your throat while speaking; vibration indicates a voiced sound.

What is the difference between voiced and unvoiced sounds?

Voiced sounds involve vocal cord vibration, while unvoiced sounds do not.

Why does changing one articulatory feature matter?

Changing one articulatory feature can create a completely different phoneme and change meaning.

Approximately how many phonemes does English contain?

English contains approximately 45 phonemes.

Do all languages use the same number of phonemes?

No, languages differ in how many phonemes they use.

Why are phoneme distinctions language-dependent?

A contrast that changes meaning in one language may not matter in another language.

What example was given of language-dependent phoneme distinctions?

The /r/ and /l/ distinction matters in English but is less meaningful in Japanese.

What is the speech signal?

The speech signal is the continuous stream of sound produced during speech.

Why is speech perception difficult?

Speech is continuous and overlapping, so listeners must separate and identify sounds accurately.

What is speech segmentation?

Speech segmentation is the process of dividing continuous speech into distinct words and phonemes.

What is coarticulation?

Coarticulation occurs when phonemes overlap during speech production.

Why does coarticulation make speech perception complex?

The same phoneme can have different acoustic patterns depending on surrounding sounds.

Give an example of coarticulation from the lecture.

The sound in “see” differs acoustically from the same phoneme in “sue.”

Why must the perceptual system “read past” variability?

It must identify phonemes despite acoustic differences caused by context.

What is categorical perception?

Categorical perception is perceiving stimuli as belonging to discrete categories despite gradual physical changes.

How does categorical perception apply to speech?

Listeners sharply distinguish between phoneme categories like /b/ and /p/.

What are listeners highly sensitive to in categorical perception?

Differences between phoneme categories.

What are listeners relatively insensitive to in categorical perception?

Differences within the same phoneme category.

What is a speech continuum?

A speech continuum is a gradual acoustic change between two phonemes, such as “ba” to “pa.”

What acoustic feature was manipulated in the “ba” to “pa” continuum?

Voice onset time (VOT).

What is voice onset time (VOT)?

Voice onset time is the delay between releasing a consonant and starting vocal cord vibration.

How does actual speech perception differ from hypothetical perception data?

Perception changes abruptly rather than gradually.

How do listeners label sounds in categorical perception tasks?

They categorise sounds into distinct labels such as “ba” or “pa” with no intermediate category.

Why is categorical perception useful?

It helps people focus on meaningful distinctions while ignoring irrelevant variation.

How does categorical perception support communication?

It allows listeners to rapidly distinguish meaningful speech sounds.

What example demonstrates the importance of categorical perception for meaning?

“Take a bath” versus “take a path.”

What is one major feature of speech perception?

Speech perception relies on linguistic knowledge, not just acoustic information.

Why is speech perception more complex than simple sound detection?

Listeners must interpret variable, overlapping, and continuous acoustic signals.

What was one learning outcome related to language and attention?

To explain how language guides attention and shapes perception.

How can language guide attention?

Language directs attention toward distinctions that are meaningful within that language.

What area of perception was used to demonstrate language guiding attention?

Colour perception.

What study was discussed about colour perception and language?

Roberson, Davies, and Davidoff (2000).

What was the main aim of Roberson et al. (2000)?

To investigate whether colour categories are universal across cultures.

What did Roberson et al. (2000) suggest about colour categories?

Colour categories are shaped by language and are not universal.

What task did participants complete in Roberson et al. (2000)?

Colour naming tasks using Munsell colour chips.

What are Munsell colour chips?

Standardised coloured samples used in colour perception research.

What were participants asked to do in the colour naming task?

Name each colour chip shown individually.

What additional task did participants complete after naming colours?

They selected the best example of each colour term they used.

What memory task was used in Roberson et al. (2000)?

A colour memory task involving delayed recognition of colour chips.

How did the colour memory task work?

A colour chip was shown for five seconds, followed by a 30-second delay before selecting the matching chip from 40 options.

Why did researchers use a portable light box?

To standardise illumination across cultures and eliminate daylight differences.

What was the significance of standardising illumination?

It controlled for environmental differences that could affect colour perception.

According to the lecture, is the effect about vocabulary alone?

No, it is about how language directs attention.

What criticism was raised about remote communities in colour studies?

Researchers questioned how representative remote communities are.

What did Roberson et al. (2004) investigate?

Colour perception across English, Berinmo, and Himba speakers.

Who are the Himba?

Semi-nomadic tribespeople from Southern Africa studied in colour perception research.

What did Roberson et al. (2004) find about Himba speakers?

They showed categorical perception at their own language-specific category boundaries.

What does this finding suggest about colour perception?

Colour perception is influenced by linguistic categories.

What colours showed high agreement across groups?

Saturated colours.

What colours showed low agreement across groups?

Desaturated colours.

According to Roberson et al. (2004), what shapes adults’ cognitive organisation of colour?

The colour categories provided by their language.

According to the lecture, what are the three dimensions of colour perception?

Hue, saturation, and lightness.

How do more colour words affect attention?

More colour words increase attention to category boundaries.

How does attention influence cognition?

Attention shapes perception, memory, and categorisation.

What does the lecture conclude about language and perception?

Language changes what people notice.

What is linguistic relativity?

The idea that language influences thought and perception.

What is the Whorfian hypothesis?

The theory that language determines thought.

What is the modern view of linguistic relativity?

Language guides attention rather than fully determining thought.

According to the modern view, how does language affect cognition?

Language influences memory, categorisation, and reasoning through attention.

Are language effects considered permanent according to the lecture?

No, they are real but reversible.

What can override language effects on cognition?

Context and task demands.

What example was mentioned to support linguistic variability?

Cardinal directions vary significantly across languages.

What concern was raised about English in cognitive science?

Cognitive science over-relies on English-speaking participants.

Why is English dominant in cognitive science research?

English is the global lingua franca and scientific default.

Who are most cognitive science participants?

Monolingual speakers of Standard American or British English.

Why is reliance on English problematic?

English is only one of over 7000 languages and may not represent universal cognition.

What question does the lecture raise about English-speaking participants?

Whether findings generalise to different cognitive and attentional profiles.

What article was discussed regarding English-language dominance?

Blasi, Henrich, and Adamou (2022).

What was the main argument of Blasi et al. (2022)?

Over-reliance on English hinders cognitive science.

What does the lecture suggest about theories based on English speakers?

They are often incorrectly treated as universal theories of cognition.

According to the lecture summary, how can language shape perception?

Language guides attention toward particular distinctions.

How does language-guided attention affect cognition?

It alters perceptual sensitivity, memory, and experience.

According to the summary, what do listeners rely on during speech perception?

Linguistic knowledge to segment and interpret speech.

Why is speech perception not purely acoustic?

Because interpretation depends on prior linguistic categories and knowledge.

What is one key implication of categorical perception?

Humans perceive speech sounds as discrete categories rather than continuous variation.

Why is categorical perception adaptive?

It improves communication efficiency by simplifying speech interpretation.

What is the relationship between attention and categorisation?

Attention influences how stimuli are grouped into categories.

How does language affect memory according to the lecture?

Language-guided attention changes what information is encoded and remembered.

What is a key criticism of traditional cognitive science research?

It often assumes findings from English speakers apply universally.

What broad conclusion can be drawn from the lecture?

Language shapes attention, perception, categorisation, and aspects of cognition.
