Language-relative construal of individuation constrained by universal ontology: revisiting language universals and linguistic relativity

Objects and substances bear fundamentally different ontologies. In this article, we examine the relations between language, the ontological distinction with respect to individuation, and the world. Specifically, in cross‐linguistic developmental studies that follow Imai and Gentner (1997) , we examine the question of whether language influences our thought in different forms, like (1) whether the language‐specific construal of entities found in a word extension context ( Imai & Gentner, 1997 ) is also found in a nonlinguistic classification context; (2) whether the presence of labels per se, independent of the count‐mass syntax, fosters ontology‐based classification; (3) in what way, if at all, the count‐mass syntax that accompanies a label changes English speakers' default construal of a given entity? On the basis of the results, we argue that the ontological distinction concerning individuation is universally shared and functions as a constraint on early learning of words. At the same time, language influences one's construal of entities cross‐lingistically and developmentally, and causes a temporary change of construal within a single language. We provide a detailed discussion of how each of these three ways language may affect the construal of entities, and discuss how our universally possessed knowledge interacts with language both within a single language and in cross‐linguistic context.     

Grammatical gender and inferences about biological properties in german-speaking children

In German, nouns are assigned to one of the three gender classes. For most animal names, however, the assignment is independent of the referent's biological sex. We examined whether German-speaking children understand this independence of grammar from semantics or whether they assume that grammatical gender is mapped onto biological sex when drawing inferences about sex-specific biological properties of animals. Two cross-linguistic studies comparing German-speaking and Japanese-speaking preschoolers were conducted. The results suggest that German-speaking children utilize grammatical gender as a cue for inferences about sex-specific properties of animals. Further, we found that Japanese- and German-speaking children recruit different resources when drawing inferences about sex-specific properties: Whereas Japanese children paralleled their pattern of inference about properties common to all animals, German children relied on the grammatical gender class of the animal. Implications of these findings for studying the relation between language and thought are discussed.     

Heuristics in learning classifiers: The acquisition of the classifier system and its implications for the nature of lexical acquisition

Classifiers are like nouns in that they classify entities in the world into lexical categories. However, the lexical nature of the classifier system is very different from that of nouns. We discuss how Japanese and Chinese children learn the meanings of classifiers. We focus on two specific questions: How classifier acquisition is different from noun acquisition; and what the prerequisites are for spontaneously extracting the meanings of classifiers. It is shown that children are very conservative in assigning meaning to classifiers. The pace of learning largely depends on semantic complexity, across languages and within each language. Furthermore, we suspect that learning the meanings of classifiers requires a certain cognitive ability – an ability to synthesize pieces of partial knowledge and form them into a cohesive whole. It may be only when children have developed such an ability that they are able to extract the complex semantic rules of classifiers on their own. We conclude that children take very different routes in learning nouns and classifiers: Unlike noun acquisition, classifier acquisition is guided by a slow, bottom-up process.     

Dimensional,similarity, and configurai classification of integral and separable stimuli

Subjects classified sets of two-dimensional stimuli into two or three groups in any way they wished. For integral stimuli, classification was based on numerical balance and the similarity structure. For separable stimuli, classification was based on the dimensional structure and the configurai properties of the stimulus set. These results replicate and extend those of Handel and Imai (1972). In addition, they suggest that no closed set of stimulus concepts is possible.     

Grouping and trajectory storage in multiple object tracking: impairments due to common item motions

In our natural viewing, we notice that objects change their locations across space and time. However, there has been relatively little consideration of the role of motion information in the construction and maintenance of object representations. We investigated this question in the context of the multiple object tracking (MOT) paradigm, wherein observers must keep track of target objects as they move randomly amid featurally identical distractors. In three experiments, we observed impairments in tracking ability when the motions of the target and distractor items shared particular properties. Specifically, we observed impairments when the target and distractor items were in a chasing relationship or moved in a uniform direction. Surprisingly, tracking ability was impaired by these manipulations even when observers failed to notice them. Our results suggest that differentiable trajectory information is an important factor in successful performance of MOT tasks. More generally, these results suggest that various types of common motion can serve as cues to form more global object representations even in the absence of other grouping cues.     

On the equivalence of superordinate concepts

Psychological studies of superordinates have generally treated them as equivalent. However, many languages distinguish mass superordinates (e.g., clothing) from count superordinates (e.g., vehicle). In the present paper, experimental evidence is presented which suggests that the two types of superordinates are conceptually distinct as well. One study showed that the members of mass superordinates more often co-occur. A second study showed that people more often interact with the members of mass superordinates in temporal proximity whereas people primarily interact with single members of count superordinates on a specific occasion. Also, properties that characterize an individual are a more salient aspect of count superordinates. These findings imply that mass superordinates refer to unindividuated groups of objects, united by spatial and functional contiguity. Two other studies supported this hypothesis by showing that the class inclusion relation between a single object and a category is stronger for count superordinates. Taken together, the findings suggest that mass superordinates are not true taxonomic categories. We relate the findings to previous views of superordinates and to the count/mass distinction in general.     

Commentary: Using Potential Outcomes to Understand Causal Mediation Analysis

In this commentary, we demonstrate how the potential outcomes framework can help understand the key identification assumptions underlying causal mediation analysis. We show that this framework can lead to the development of alternative research design and statistical analysis strategies applicable to the longitudinal data settings considered by Maxwell, Cole, and Mitchell (2011).     

Talking about walking: biomechanics and the language of locomotion

What drives humans around the world to converge in certain ways in their naming while diverging dramatically in others? We studied how naming patterns are constrained by investigating whether labeling of human locomotion reflects the biomechanical discontinuity between walking and running gaits. Similarity judgments of a student locomoting on a treadmill at different slopes and speeds revealed perception of this discontinuity. Naming judgments of the same clips by speakers of English, Japanese, Spanish, and Dutch showed lexical distinctions between walking and running consistent with the perceived discontinuity. Typicality judgments showed that major gait terms of the four languages share goodness-of-example gradients. These data demonstrate that naming reflects the biomechanical discontinuity between walking and running and that shared elements of naming can arise from correlations among stimulus properties that are dynamic and fleeting. The results support the proposal that converging naming patterns reflect structure in the world, not only acts of construction by observers.     

Attitudes Toward Violence Against Women: A Cross-Nation Study

An understanding of attitudes toward violence against women is vital for effective prevention strategies. In this study we examined attitudes regarding violence against women in samples of undergraduate women and men students from four countries: India, Japan, Kuwait, and the United States. Attitudes toward sexual assault and spousal physical violence differed between men and women and across the four countries. Variations in gender differences across countries indicated that, for attitudes regarding sexual assault of women in particular, sociocultural factors may be a stronger influence than gender. Findings suggest the importance of examining differences within the larger sociocultural context of political, historical, religious, and economic influences on attitudes toward gender roles and violence against women.
