Experiment 1
1. Up to 7000 languages
2. From 10 major language families
3. More than half of world population are bilinguals or multilinguals
4. A language dies every two weeks

Ways to categorize the world
Certain expressions are deeply engrained in the speaker’s culture.
The Eskimo language has a large number of words for the word snow.
‘apun’= “snow on the ground”‘qanikca’= “hard snow on the ground”, ‘utak’= “block of snow”.

The Sapir-Whorf Hypothesis
Edward SapirBenjamin Lee Whorf
Language is not only for expression
but also helps organise our
thought. Diverse languages impose
different conceptual
categories on their speakers.
PSY241 - 10/38
1. Linguistic determinism (strong version): The language we use determines the way we view and think
about the world around us. Learning a new language changes our ways of thinking.
2. Linguistic relativity (weak version): People who speak different languages perceive and
experience the world differently relative to their linguistic backgrounds.
The Sapir-Whorf Hypothesis
PSY241 - 11/38
Carmichael, Hogan & Walter (1932) The way an ambiguous figure is described influences how it is later recalled.

The Sapir-Whorf HypothesisGlucksberg & Weisberg (1962)
Performance enhanced if..
Available materials described in a different and unaccustomed linguistic structure, such as ‘box and tacks’, rather than ‘box of tacks’.
‘on the table there is a candle, a box of tacks, and a book of matches...’.

English- Egocentric: left, right, over there, by me- Allocentric: north, south, east, west
Tzeltal (Chiapas, Mexico)-Allocentric only: uphill, downhill, along

The Sapir-Whorf HypothesisBrown & Levinson 1993
1. The majority (60%) of Tenejapans speakers restructured the table according to the Absolute rearrangement.
2. Only a small percent of Dutch speakers restructured the table according to the Absolute rearrangement. The majority of them restructured it relatively.
PSY241 - 21/38
1.Some cognitive tasks may be affected by implicit access to the participants’ native language (hence the importance to use nonlinguistic tasks).
2.Differences in nonlinguistic tasks may be the result of ‘life-experience’ due to background difference, rather than languages.
3.Behavioural measurements only show the ‘end-product’ of cognitive processes.
The Sapir-Whorf HypothesisSo far so good?

ERP Components
Early components strongly relate to sensory brain activation and therefore depend on the physical properties of stimuli
Late components are generated by larger networks in the brain and correspond to higher processes (e.g. decision, retrieval of meaning, working memory, etc.)
N stands for negative, P for positive. Numbers either indicate order of occurrence or classical latency of peak in specific experimental conditions

Does the terminology for colours affect people’s perception of them?

Toward a theory for language-thought
language produces transient modulation of ongoing perceptual processing – the label-feedback effect (Lupyan, 2012).

Toward a theory for language-thought
PSY241 - 35/38
Information in the brain travels in a feedforward manner but not only.
Language produces transient modulation of ongoing perceptual processing.
Visual processing can be influenced by higher-level cognition
Evidence that prefrontal areas can respond to stimuli before early visual cortex.
