The debate as to whether language influences cognition has been long standing but has yielded conflicting findings across domains such as colour and kinship categories. Fewer studies have investigated systems such as nominal classification (gender, classifiers) across different languages to examine the effects of linguistic categorisation on cognition. Effective categorisation needs to be informative to maximise communicative efficiency but also simple to minimise cognitive load. It therefore seems plausible to suggest that different systems of nominal classification have implications for the way speakers conceptualise relevant entities. A suite of seven experiments was designed to test this; here we focus on our card sorting experiment, which contains two sub-tasks — a free sort and a structured sort. Participants were 119 adults across six Oceanic languages from Vanuatu and New Caledonia, with classifier inventories ranging from two to 23. The results of the card sorting experiment reveal that classifiers appear to provide structure for cognition in tasks where they are explicit and salient. The free sort task did not incite categorisation through classifiers, arguably as it required subjective judgement, rather than explicit instruction. This was evident from our quantitative and qualitative analyses. Furthermore, the languages employing more extreme categorisation systems displayed smaller variation in comparison to more moderate systems. Thus, systems that are more informative or more rigid appear to be more efficient. The study implies that the influence of language on cognition may vary across languages, and that not all nominal classification systems employ this optimal trade-off between simplicity and informativeness. These novel data provide a new perspective on the origin and nature of nominal classification.

The Relationship

The objective of this study is to investigate the effect of the gap between two different mental models on interaction performance through a quantitative way. To achieve that, an index called mental model similarity and a new method called path diagram to elicit mental models were introduced. There are two kinds of similarity: directionless similarity calculated from card sorting and directional similarity calculated from path diagram. An experiment was designed to test their influence. A total of 32 college students participated and their performance was recorded. Through mathematical analysis of the results, three findings were derived. Frist, the more complex the information structures, the lower the directional similarity. Second, directional similarity (rather than directionless similarity) had significant influence on user performance, indicating that it is more effective in eliciting mental models using path diagram than card sorting. Third, the relationship between information structures and user performance was partially mediated by directional similarity. Our findings provide practitioners with a new perspective of bridging the gap between users’ and designers’ mental models.

Objective: A small-scale exploration of the use of video analysis to study robberies. We analyze the use of weapons as part of the body posturing of robbers as they attempt to attain dominance. Methods: Qualitative analyses of video footage of 23 shop robberies. We used Observer XT software (version 12) for fine-grained multimodal coding, capturing diverse bodily behavior by various actors simultaneously. We also constructed story lines to understand the robberies as hermeneutic whole cases. Results: Robbers attain dominance by using weapons that afford aggrandizing posturing and forward movements. Guns rather than knives seemed to fit more easily with such posturing. Also, victims were more likely to show minimizing postures when confronted with guns. Thus, guns, as part of aggrandizing posturing, offer more support to robbers’ claims to dominance in addition to their more lethal power. In the cases where resistance occurred, robbers either expressed insecure body movements or minimizing postures and related weapon usage or they failed to impose a robbery frame as the victims did not seem to comprehend the situation initially. Conclusions: Video analysis opens up a new perspective of how violent crime unfolds as sequences of bodily movements. We provide methodological recommendations and suggest a larger scale comparative project.

Gender System

Nominal classification remains a fascinating topic but in order to make further progress we need greater clarity of definition and analysis. Taking a Canonical Typology approach, we use canonical gender as an ideal against which we can measure the actual gender systems we find in the languages of the world. Building on previous work on canonical morphosyntactic features, particularly on how they intersect with canonical parts of speech, we establish the distinctiveness of gender, reflected in the Canonical Gender Principle: In a canonical gender system, each noun has a single gender value. We develop three criteria associated with this principle, which together ensure that canonically a noun has exactly one gender value; we give examples of non-canonicity for each criterion, thus gradually building the typology. This is the essential groundwork for a comprehensive typology of nominal classification: the Canonical Typological approach allows us to tease apart clusterings of properties and to characterize individual properties with respect to a canonical ideal, rather than requiring us to treat the entire system as belonging to a single type. This approach is designed to facilitate comparisons of different noun classification systems across languages.

AbstractThe Papuan language Mian allows us to refine the typology of nominal classification. Mian has two candidate classification systems, differing completely in their formal realization but overlapping considerably in their semantics. To determine whether to analyse Mian as a single system or concurrent systems we adopt a canonical approach. Our criteria – orthogonality of the systems (we give a precise measure), semantic compositionality, morphosyntactic alignment, distribution across parts of speech, exponence, and interaction with other features – point mainly to an analysis as concurrent systems. We thus improve our analysis of Mian and make progress with the typology of nominal classification.

Qualitative Analyses

The principal aim of this study is to examine the Spanish modal verb deber ‘must’ in its deontic readings, relating it to the notions of evidentiality and intersubjectivity. Deber has often been compared to the modal verb tener que ‘have to’ and described in rather vague terms, for example as an expression of weak, internal obligation, but this paper proposes that it is better understood as an intersubjective verb. Both quantitative and qualitative analyses have been carried out, with a special focus on the in-depth qualitative study. It will be shown that deontic deber can convey evidential meanings when used in the conditional form. First, it can refer to a norm shared between the speaker and the hearer, and, second, it can convey an inferential process, a conclusion presented by the speaker, which is based on shared information, available to a larger group (or all) of the interlocutors. Evidentiality is regarded here as an intersubjective strategy, used when the speaker wants to reach consensus, arguing for the most reasonable, morally defensible way to act. Thus, this study also offers a new perspective of evidentiality, looking at this notion in interaction with deontic modality instead of epistemic modality, which is usually the case.

The Way

The entrenched nature of the gender/classifier dichotomy stands in the way of better typologies of nominal classification. How can we move beyond it to a more integrated view of nominal classification? Looking at a range of kinds of data from the Australian language Mawng, it is clear that our understanding of many less well-known nominal classification systems reflects a lack of data on how the system is used. Mawng has what seems like a well-behaved system of five genders, including gender agreement in the verb. However, the genders, like classifiers, play a crucial role in constructing meaning in discourse, often in the absence of nouns. Nominal classification systems must be contextualized in terms of their roles in constructing meaning in discourse, in order to do them justice in typologies. Greater emphasis on the flexibility of nominal classification systems and less on the role of nouns will also move efforts forward.

Insight Into

This is a commentary on Kemmerer (2016), Categories of object concepts across languages and brains: The relevance of nominal classification systems to Cognitive Neuroscience. The consequences of nominal classification systems for the organization of the conceptual system are consistent with several theories and findings in cognitive psychology. Concepts are flexible; they are categorized in various ways and change across contexts. Languages with nominal classification systems provide an interesting source of data that can give further insight into the mechanisms of flexible concepts.
