A series of experiments sought to replicate and extend the classic studies of Rosch Heider on the Dani with a comparable group from Papua New Guinea who speak Berinmo, which has 5 basic color terms. Her results have been interpreted as clearly supporting universal color categories. Some results could, however, be interpreted as supporting linguistic relativity. We investigated naming and memory for highly saturated `focal', `non-focal' and low saturation stimuli from around the color space. Recognition of desaturated colors did appear to reflect color vocabulary. When response bias was controlled, there was no recognition advantage for focal stimuli. Pairedassociate learning also failed to show an advantage for focal stimuli. We further examined `Categorical Perception' effects at the boundaries of both English and Berinmo linguistic categories. These were found, in both populations, only for existing linguistic categories. Whilst Berinmo speakers, like those of all other languages hit...

This study investigated whether different lexicalization patterns of motion events in English and Spanish predict how speakers of these languages perform in non-linguistic tasks. Using 36 motion events, we compared English and Spanish speakers' linguistic descriptions to their performance on two non-linguistic tasks: recognition memory and similarity judgments. We investigated the effect of language processing on non-linguistic performance by varying the nature of the encoding before testing for recognition and similarity. Participants encoded the events while describing them verbally or not. No effect of language was obtained in the recognition memory task after either linguistic or non-linguistic encoding and in the similarity task after non-linguistic encoding. We did find a linguistic effect in the similarity task after verbal encoding, an effect that conformed to languagespecific patterns. Linguistic descriptions directed attention to certain aspects of the events later used to make a non-linguistic judgment. This suggests that linguistic and non-linguistic performance are dissociable, but language-specific regularities made available in the experimental context may mediate the speaker's performance in specific tasks.

Many languages have a grammatical gender system whereby all nouns are assigned a gender (most commonly feminine, masculine, or neuter). Two studies examined whether (1) the assignment of genders to nouns is truly arbitrary (as has been claimed), and (2) whether the grammatical genders assigned to nouns have semantic consequences. In the first study, English speakers intuitions about the genders of animals (but not artifacts) were found to correlate with the grammatical genders assigned to the names of these objects in Spanish and German. These findings suggest that the assignment of genders to nouns is not entirely arbitrary but may to some extent reflect the perceived masculine or feminine properties of the nouns referents. Results of the second study suggested that peoples ideas about the genders of objects are strongly influenced by the grammatical genders assigned to these objects in their native language. Spanish and German speakers memory for object--name pairs (e.g., apple--Patricia) was better for pairs where the gender of the proper name was congruent with the grammatical gender of the object name (in their native language), than when the two genders were incongruent.

Languages vary strikingly in how they encode motion events. In some languages (e.g. English), manner of motion is typically encoded within the verb, while direction of motion information appears in modifiers. In other languages (e.g. Greek), the verb usually encodes the direction of motion, while the manner information is often omitted, or encoded in modifiers. We designed two studies to investigate whether these language-specific patterns affect speakers' reasoning about motion. We compared the performance of English and Greek children and adults (a) in nonlinguistic (memory and categorization) tasks involving motion events, and (b) in their linguistic descriptions of these same motion events. Even though the two linguistic groups differed significantly in terms of their linguistic preferences, their performance in the nonlinguistic tasks was identical. More surprisingly, the linguistic descriptions given by subjects within language also failed to correlate consistently with their memory and categorization performance in the relevant regards. For the domain studied, these results are consistent with the view that conceptual development and organization are largely independent of language-specific labeling practices. The discussion emphasizes that the necessarily sketchy nature of language use assures that it will be at best a crude index of thought.

van de academische graad van doctor in de wetenschappen, in het openbaar te verdedigen op vrijdag 8 maart 2002. Acknowledgements I started as a research assistant in the Artificial Intelligence Laboratory in autumn 1996. My first interests were into behavioural robotics and robot ecosystems. As a continuation to my “licentiaats ” thesis I started building a camera system to extend the sensory perception of the lab’s robots (Belpaeme and Birk, 1997a,b; Belpaeme, 1998; Birk and Belpaeme, 1998; Birk et al., 1998, 1999; Belpaeme and Birk, 2001). It was around that time when Luc Steels got interested in the origins of language. His early experiments formed the seed for what is now one of the most important paradigms for exploring linguistic interactions with computer simulations. Luc soon wanted more and had plans to implement a language experiment in the real world, for which I delivered the visual perception (Belpaeme et al., 1998; Belpaeme, 1999). This got me interested in visual features, and my research

Language plays a pervasive role in our day-to-day experience and is likely to have an effect on other non-linguistic aspects of life. At the same time, language is itself constrained by the world. In this paper we study this interaction using Playpen, a connectionist model of the acquisition of word meaning. We argue that the interaction between linguistic and non-linguistic categories depends on the pattern of correlations in the world and on their relation to the correlations defined by words. We then discuss three kinds of possible interactions and present simulations of each using Playpen, a neural-network model of the acquisition of word meaning.

The World Color Survey [WCS] is a research project that was undertaken to validate, invalidate or – most likely – modify the main findings of Berlin and Kay (1969) [B&K]: (1) that there exist universal cross-linguistic constraints on color naming, and (2) that basic color terminology systems tend to develop in a partially fixed order. To this end, the WCS collected color naming data from speakers of 110 unwritten languages. The data have recently been compiled into a unified data archive, available online at
