Grounded Cognition, Linguistic Relativity, and Abstract Concepts

Kemmerer's paper convincingly claims that the grounded cognition model (GCM) entails linguistic relativity. Here, we underline that tackling linguistic relativity and cultural differences is vital for GCM. First, it allows GCM to focus more on flexible rather than stable aspects of cognition. Second, it highlights the centrality of linguistic experience for human cognition. While GCM-inspired research underscored the similarity between linguistic and nonlinguistic concepts, it is now paramount to understand when and how language(s) influence knowledge. To this aim, we argue that linguistic variation might be particularly relevant for more abstract concepts-which are more debatable and open to revisions.

The Iconicity Ring Hypothesis Bridges the Gap Between Symbol Grounding and Linguistic Relativity

Kemmerer captured the drastic change in theories of word meaning representations, contrasting the view that word meaning representations are amodal and universal, with the view that they are grounded and language-specific. However, he does not address how language can be simultaneously grounded and language-specific. Here, we approach this question from the perspective of language acquisition and evolution. We argue that adding a new element-iconicity-is critically beneficial and offer the iconicity ring hypothesis, which explains how language-specific, secondary iconicity might emerge from biologically grounded and universally shared iconicity in the course of language acquisition and evolution.

Language is a Source of Grounding and a Mode of Action

Kemmerer argues that grounded cognition explains how language-specific semantic structures can influence nonlinguistic cognition. In this commentary, I argue that his proposal fails to fully consider the possibility that language itself can serve as a source of grounding. Our concepts are not merely shaped by a disembodied language system; they emerge in the context of linguistic experience and action. This inclusive approach to grounded cognition offers an expanded conception of the phenomena associated with linguistic relativity. I provide empirical and theoretical reasons to adopt this theoretical perspective.

Language Entails Linguistic Relativity

This commentary addresses the challenge of linking an individual-grounded theory of concepts to a phenomenon that assumes conceptual conventions at population level (linguistic relativity). We distinguish I-concepts (individual, interior, imagistic) from L-concepts (linguistic, labeled, local) and see that quite different causal processes are often conflated under the term "concepts." I argue that the Grounded Cognition Model (GCM) entails linguistic relativity only to the extent that it imports L-concepts into its scope, which it can hardly avoid doing given that practitioners require language to coordinate around their theory and findings. I conclude that what entails linguistic relativity is not the GCM but language itself.

Grounded Cognition Entails Linguistic Relativity: A Neglected Implication of a Major Semantic Theory

According to the popular Grounded Cognition Model (GCM), the sensory and motor features of concepts, including word meanings, are stored directly within neural systems for perception and action. More precisely, the core claim is that these concrete conceptual features reuse some of the same modality-specific representations that serve to categorize experiences involving the relevant kinds of objects and events. Research in semantic typology, however, has shown that word meanings vary significantly across the roughly 6500 languages in the world. I argue that this crosslinguistic semantic diversity has significant yet previously unrecognized theoretical consequences for the GCM. In particular, to accommodate the typological data, the GCM must assume that the concrete features of word meanings are not merely stored within sensory/motor brain systems, but are represented there in ways that are, to a nontrivial degree, language-specific. Moreover, it must assume that these conceptual representations are also activated during the nonlinguistic processing of the relevant kinds of objects and events (e.g., during visual perception and action planning); otherwise, they would not really be grounded, which is to say, embedded inside sensory/motor systems. Crucially, however, such activations would constitute what is traditionally called linguistic relativity-that is, the influence of language-specific semantic structures on other forms of cognition. The overarching aim of this paper is to elaborate this argument more fully and explore its repercussions. To that end, I discuss in greater detail the key aspects of the GCM, the evidence for crosslinguistic semantic diversity, pertinent work on linguistic relativity, the central claim that the GCM entails linguistic relativity, some initial supporting results, and some important limitations and future directions.

Grounded Cognition Entails Linguistic Relativity: Response to Commentators

In this paper, I respond to eight commentaries on my target article called "Grounded cognition entails linguistic relativity: A neglected implication of a major semantic theory." The commentaries span a broad range of disciplines and perspectives. I have organized my response around the following topics: (1) an introductory synopsis of my main argument; (2) grounded versus amodal theories of concepts; (3) language-specific versus language-independent concepts; (4) language, culture, and cognition; (5) language itself as a source of conceptual grounding; (6) abstract concepts, linguistic relativity, and contextual and individual variability; (7) word meanings as language-specific predictions; and (8) some final remarks about the importance of cross-linguistic diversity.

Not When But Whether: Modality and Future Time Reference in English and Dutch

Previous research on linguistic relativity and economic decisions hypothesized that speakers of languages with obligatory tense marking of future time reference (FTR) should value future rewards less than speakers of languages which permit present tense FTR. This was hypothesized on the basis of obligatory linguistic marking (e.g., will) causing speakers to construe future events as more temporally distal and thereby to exhibit increased "temporal discounting": the subjective devaluation of outcomes as the delay until they will occur increases. However, several aspects of this hypothesis are incomplete. First, it overlooks the role of "modal" FTR structures which encode notions about the likelihood of future outcomes (e.g., might). This may influence "probability discounting": the subjective devaluation of outcomes as the probability of their occurrence decreases. Second, the extent to which linguistic structures are subjectively related to temporal or probability discounting differences is currently unknown. To address these, we elicited FTR language and subjective ratings of temporal distance and probability from speakers of English, which exhibits strongly grammaticized FTR, and Dutch, which does not. Several findings went against the predictions of the previous hypothesis: Framing an FTR statement in the present ("Ellie arrives later on") versus the future tense ("…will arrive…") did not affect ratings of temporal distance; English speakers rated future statements as relatively more temporally proximal than Dutch speakers; and English and Dutch speakers rated future tenses as encoding high certainty, which suggests that obligatory future tense marking might result in less discounting. Additionally, compared with Dutch speakers, English speakers used more low-certainty terms in general (e.g., may) and as a function of various experimental factors. We conclude that the prior cross-linguistic observations of the link between FTR and psychological discounting may be caused by the connection between low-certainty modal structures and probability discounting, rather than future tense and temporality.

The Effect of Language-Specific Characteristics on English and Japanese Speakers' Ability to Recall Number Information

The current paper presents two experiments investigating the effect of presence versus absence of compulsory number marking in a native language on a speaker's ability to recall number information from photos. In Experiment 1, monolingual English and Japanese adults were shown a sequence of 110 photos after which they were asked questions about the photos. We found that the English participants showed a significantly higher accuracy rate for questions testing recall for number information when the correct answer was "2" (instead of "1") than Japanese participants. In Experiment 2, English and Japanese adults engaged in the same task as in Experiment 1 with an addition that explored reasons for the results found in Experiment 1. The results of Experiment 2 were in line with the results of Experiment 1, but also suggested that the results could not be attributed to differences in guessing patterns between the two groups or the type of linguistic constructions used in the test situations. The current study suggests that native language affects speakers' ability to recall number information from scenes and thus provides evidence for the Whorfian hypothesis.

Flexing Gender Perception: Brain Potentials Reveal the Cognitive Permeability of Grammatical Information

A growing body of recent research suggests that verbal categories, particularly labels, impact categorization and perception. These findings are commonly interpreted as demonstrating the involvement of language on cognition; however, whether these assumptions hold true for grammatical structures has yet to be investigated. In the present study, we investigated the extent to which linguistic information, namely, grammatical gender categories, structures cognition to subsequently influence categorical judgments and perception. In a nonverbal categorization task, French-English bilinguals and monolingual English speakers made gender-associated judgments about a set of image pairs while event-related potentials were recorded. The image sets were composed of an object paired with either a female or male face, wherein the object was manipulated for their conceptual gender relatedness and grammatical gender congruency to the sex of the following target face. The results showed that grammatical gender modulated the N1 and P2/VPP, as well as the N300 exclusively for the French-English bilinguals, indicating the inclusion of language in the mechanisms associated with attentional bias and categorization. In contrast, conceptual gender information impacted the monolingual English speakers in the later N300 time window given the absence of a comparable grammatical feature. Such effects of grammatical categories in the early perceptual stream have not been found before, and further provide grounds to suggest that language shapes perception.

Grammatical gender and linguistic relativity: A systematic review

Many languages assign nouns to a grammatical gender class, such that "bed" might be assigned masculine gender in one language (e.g., Italian) but feminine gender in another (e.g., Spanish). In the context of research assessing the potential for language to influence thought (the linguistic relativity hypothesis), a number of scholars have investigated whether grammatical gender assignment "rubs off" on concepts themselves, such that Italian speakers might conceptualize beds as more masculine than Spanish speakers do. We systematically reviewed 43 pieces of empirical research examining grammatical gender and thought, which together tested 5,895 participants. We classified the findings in terms of their support for this hypothesis and assessed the results against parameters previously identified as potentially influencing outcomes. Overall, we found that support was strongly task- and context-dependent, and rested heavily on outcomes that have clear and equally viable alternative explanations. We also argue that it remains unclear whether grammatical gender is in fact a useful tool for investigating relativity.

Language and Thought in the Motion Domain: Methodological Considerations and New Empirical Evidence

This study investigates whether there is a relation between how motion is linguistically expressed and how it is conceptualised. To do this, native speakers of two languages that differ typologically in how they encode telic motion (English and Spanish) are compared in both a verbal and a non-verbal experiment. The preferred non-verbal methods to test the linguistic relativity hypothesis in this domain have so far been recognition memory and binary judgments. This study questions the experimental validity of these approaches and implements an alternative method which combines similarity ratings with a verbal interference manipulation. The results reported here constitute evidence against linguistic relativity and in support of cognitive universalism.

Space-pitch associations differ in their susceptibility to language

To what extent are links between musical pitch and space universal, and to what extent are they shaped by language? There is contradictory evidence in support of both universality and linguistic relativity presently, leaving the question open. To address this, speakers of Dutch who talk about pitch in terms of spatial height and speakers of Turkish who use a thickness metaphor were tested in simple nonlinguistic space-pitch association tasks. Both groups showed evidence of a thickness-pitch association, but differed significantly in their height-pitch associations, suggesting the latter may be more susceptible to language. When participants had to match pitches to spatial stimuli where height and thickness were opposed (i.e., a thick line high in space vs. a thin line low in space), Dutch and Turkish differed in their relative preferences. Whereas Turkish participants predominantly opted for a thickness-pitch interpretation-even if this meant a reversal of height-pitch mappings-Dutch participants favored a height-pitch interpretation more often. These findings provide new evidence that speakers of different languages vary in their space-pitch associations, while at the same time showing such associations are not equally susceptible to linguistic influences. Some space-pitch (i.e., height-pitch) associations are more malleable than others (i.e., thickness-pitch).

Alternative spin on phylogenetically inherited spatial reference frames

People make use of different frames of reference (north-south; left-right) to talk about space. To explore the cognitive capacity that children bring to learning spatial language, Haun, Rapold, Call, Janzen, and Levinson (2006) examined children's ability to notice and abstract invariant frames of references across instances. They found that 4-year-olds and non-human great apes often noticed environment-defined allocentric relations and not body-defined egocentric ones, leading them to conclude that preschoolers are ready to learn environment-defined terms (e.g. "uphill"), but not body-defined ones (e.g., "left"). However, such a conclusion may be premature. In four new experiments we demonstrate that the previous findings could be an artifact of specific task constraints. With minor experiment modifications, similar-aged children readily noticed egocentric relations. Reviewing additional research, we provide an account of what makes acquiring frames of reference easy or difficult, and why full mastery of terms like "left" and "right" may take many years under normal circumstances.

Linguistic features of fragrances: The role of grammatical gender and gender associations

Odors are often difficult to identify and name, which leaves them vulnerable to the influence of language. The present study tests the boundaries of the effect of language on odor cognition by examining the effect of grammatical gender. We presented participants with male and female fragrances paired with descriptions of masculine or feminine grammatical gender. In Experiment 1 we found that memory for fragrances was enhanced when the grammatical gender of a fragrance description matched the gender of the fragrance. In Experiment 2 we found memory for fragrances was affected by both grammatical gender and gender associations in fragrance descriptions – recognition memory for odors was higher when the gender was incongruent. In sum, we demonstrated that even subtle aspects of language can affect odor cognition.

Blue is in the Eye of the Beholder: A Cross-Linguistic Study on Color Perception and Memory

The linguistic relativity hypothesis states that the language one speaks affects how one thinks. Color categorization across languages has often been studied in order to examine the hypothesis. However, those studies often rely on uniform color stimuli or focus on one aspect of cognition. In experiment one, we examined how Russian- and English-speaking participants rated the color of blue/grey eyes perceptually and from memory. Russian-speakers are more likely to describe such eyes as grey, whereas English-speakers are more likely to describe them as blue. Participants were randomly assigned to one of three conditions. In the first condition (perception), participants saw the color scale and an eye picture simultaneously and then chose the color that best matched the picture. In the second condition (memory), participants matched the color of an eye to the color scale from memory. The third condition (label) was similar to the second, except participants labeled the eye orally before matching the color from memory. A Bayesian analysis showed that Russian-speakers rated the eyes greyer than did English-speakers in the memory and label conditions, but not perception conditions. In experiment two, we examined how short-term linguistic memory traces are related to color memory. Overall, results find nuanced support for the linguistic relativity hypothesis: language affects color memory more than color perception.

Keeping the Result in Sight and Mind: General Cognitive Principles and Language-Specific Influences in the Perception and Memory of Resultative Events

We study how people attend to and memorize endings of events that differ in the degree to which objects in them are affected by an action: Resultative events show objects that undergo a visually salient change in state during the course of the event (peeling a potato), and non-resultative events involve objects that undergo no, or only partial state change (stirring in a pan). We investigate general cognitive principles, and potential language-specific influences, in verbal and nonverbal event encoding and memory, across two experiments with Dutch and Estonian participants. Estonian marks a viewer's perspective on an event's result obligatorily via grammatical case on direct object nouns: Objects undergoing a partial/full change in state in an event are marked with partitive/accusative case, respectively. Therefore, we hypothesized increased saliency of object states and event results in Estonian speakers, as compared to speakers of Dutch. Findings show (a) a general cognitive principle of attending carefully to endings of resultative events, implying cognitive saliency of object states in event processing; (b) a language-specific boost on attention and memory of event results under verbal task demands in Estonian speakers. Results are discussed in relation to theories of event cognition, linguistic relativity, and thinking for speaking.

Timeline blurring in fluent Chinese-English bilinguals

Linguistic relativity effects arising from differences in terminology and syntax between languages have now been established in various domains of human cognition. Although metaphors have been shown to affect time conceptualisation, there is little evidence to date that the presence or absence of tense within a given language can affect how one processes temporal sequences of events. Here, we set out to characterise how native speakers of Mandarin Chinese - a tenseless language- deal with reference time misalignment using event-related brain potentials. Fluent Chinese-English participants and native speakers of English made acceptability judgements on sentences in which the adjunct clause started with the connective 'after' and was either temporally aligned or not with the main clause in terms of reference time conveyed by the verb. Native speakers of English failed to overtly report such reference time misalignments between clauses, but significant N400 modulations showed that they nevertheless required additional semantic processing effort. Chinese speakers, however, showed no such N400 modulation suggesting that they did not covertly detect reference time misalignments between clauses in real time. Critically, all participants manifested normal sentence comprehension as shown by a standard N400 semantic violation elicited by incongruent endings. We conclude that Chinese speakers of English experience difficulties locating events on a timeline in relation to one another when temporal information is conveyed by tense.

More Than the Eye Can See: A Computational Model of Color Term Acquisition and Color Discrimination

We explore the following two cognitive questions regarding crosslinguistic variation in lexical semantic systems: Why are some linguistic categories-that is, the associations between a term and a portion of the semantic space-harder to learn than others? How does learning a language-specific set of lexical categories affect processing in that semantic domain? Using a computational word-learner, and the domain of color as a testbed, we investigate these questions by modeling both child acquisition of color terms and adult behavior on a non-verbal color discrimination task. A further goal is to test an approach to lexical semantic representation based on the principle that the more languages label any two situations with the same word, the more conceptually similar those two situations are. We compare such a crosslinguistically based semantic space to one based on perceptual similarity. Our computational model suggests a mechanistic explanation for the interplay between term frequency and the semantic closeness of learned categories in developmental error patterns for color terms. Our model also indicates how linguistic relativity effects could arise from an acquisition mechanism that yields language-specific topologies for the same semantic domain. Moreover, we find that the crosslinguistically inspired semantic space supports these results at least as well as-and in some aspects better than-the purely perceptual one, thus confirming our approach as a practical and principled method for lexical semantic representation in cognitive modeling.

No grammatical gender effect on affective ratings: evidence from Italian and German languages

In this study, we tested the linguistic relativity hypothesis by studying the effect of grammatical gender (feminine vs. masculine) on affective judgments of conceptual representation in Italian and German. In particular, we examined the within- and cross-language grammatical gender effect and its interaction with participants' demographic characteristics (such as, the raters' age and sex) on semantic differential scales (affective ratings of valence, arousal and dominance) in Italian and German speakers. We selected the stimuli and the relative affective measures from Italian and German adaptations of the ANEW (Affective Norms for English Words). Bayesian and frequentist analyses yielded evidence for the absence of within- and cross-languages effects of grammatical gender and sex- and age-dependent interactions. These results suggest that grammatical gender does not affect judgments of affective features of semantic representation in Italian and German speakers, since an overt coding of word grammar is not required. Although further research is recommended to refine the impact of the grammatical gender on properties of semantic representation, these results have implications for any strong view of the linguistic relativity hypothesis.

The linguistic transparency of first language calendar terms affects calendar calculations in a second language

Calendar calculations - e.g., calculating the nth month after a certain month - are an important component of temporal cognition, and can vary cross-linguistically. English speakers rely on a verbal list representation-processing system. Chinese speakers - whose calendar terms are numerically transparent - rely on a more efficient numerical system. Does knowing a numerically transparent calendar lexicon facilitate calendar calculations in an opaque second language? Late Chinese-English bilinguals and English native speakers performed a Month and a Weekday Calculation Task in English. Directionality (forward/backward) and boundary-crossing (within/across the year/week boundary) were manipulated. English speakers relied on verbal list processing, and were slower in backward than forward calculations. In spite of the English calendar system's opaqueness, bilinguals relied on numerical processing, were slower in across- than within-boundary trials, and under some conditions had faster RTs than the native speakers. Results have implications for research on temporal cognition, linguistic relativity and bilingual cognition.

Grammatical gender affects gender perception: Evidence for the structural-feedback hypothesis

Two experiments assessed the extent to which grammatical gender provides a predictive basis for bilinguals' judgments about perceptual gender. In both experiments, French-English bilinguals and native English monolinguals were consecutively presented with images of objects manipulated for their (i) conceptual gender association and (ii) grammatical gender category and were instructed to make a decision on a subsequent target face. The experiments differed in the implicitness of the association between the object primes and target faces. Results revealed that when prior knowledge sources such as conceptual gender can be strategically used to resolve the immediate task (Experiment 1), this information was readily extracted and employed. However, grammatical gender demonstrated a more robust and persisting effect on the bilinguals' judgments, indicating that the retrieval of obligatory grammatical information is automatic and modulates perceptual judgments (Experiment 2). These results suggest that grammar enables an effective and robust means to access prior knowledge which may be independent of task requirements.

How Cross-Linguistic Differences in the Grammaticalization of Future Time Reference Influence Intertemporal Choices

According to Chen's (2013) Linguistic Savings Hypothesis (LSH), our native language affects our economic behavior. We present three studies investigating how cross-linguistic differences in the grammaticalization of future-time reference (FTR) affect intertemporal choices. In a series of decision scenarios about finance and health issues, we let speakers of altogether five languages that represent FTR with increasing strength, that is, Chinese, German, Danish, Spanish, and English, choose between hypothetical sooner-smaller and later-larger reward options. While the LSH predicts a present-bias that increases with FTR-strength, our decision makers preferred later-larger options and this future-bias increased with FTR-strength. In multiple regressions, the FTR-strength effect persisted when controlled for socioeconomic and cultural differences. We discuss why our findings deviate from the LSH and ask in how far the FTR-strength effect represents a habitual constitution of linguistic relativity or an instance of online decision framing.

Competing perspectives on frames of reference in language and thought

A study found that Dutch-speaking children who prefer an egocentric (left/right) reference frame when describing spatial relationships, and Hai||om-speaking children who use a geocentric (north/south) frame had difficulty recreating small-scale spatial arrays using their language-incongruent system (Haun, Rapold, Janzen, & Levinson, 2011). In five experiments, we reconciled these results with another study showing that English (egocentric) and Tseltal Mayan (geocentric) speakers can flexibly use both systems (Abarbanell, 2010; Li, Abarbanell, Gleitman, & Papafragou, 2011). In replicating and extending Haun et al. (Experiment 1), English- but not Tseltal-speaking children could use their language-incongruent system when the instructions used their non-preferred frame of reference. Perseveration due to task order may explain the discrepancies between present English- and previous Dutch-speaking children, while not understanding task instructions using left/right language may explain why present Tseltal- and previous Hai||om-speaking children had difficulty with their language-incongruent systems. In support, Tseltal-speaking children could use an egocentric system when the instructions were conveyed without left/right language (Experiments 2-4), and many did not know left/right language (Experiment 5). These findings help reconcile seemingly conflicting sets of results and suggest that task constraints, rather than language, determine which system is easier to use (Experiment 2 vs. 3).

Perceptual effects of linguistic category priming: the Stapel and Semin (2007) paradigm revisited in twelve experiments

Linguistic category priming is a novel paradigm to examine automatic influences of language on cognition (Semin, 2008). An initial article reported that priming abstract linguistic categories (adjectives) led to more global perceptual processing, whereas priming concrete linguistic categories (verbs) led to more local perceptual processing (Stapel & Semin, 2007). However, this report was compromised by data fabrication by the first author, so that it remains unclear whether or not linguistic category priming influences perceptual processing. To fill this gap in the literature, the present article reports 12 studies among Dutch and US samples examining the perceptual effects of linguistic category priming. The results yielded no evidence of linguistic category priming effects. These findings are discussed in relation to other research showing cultural variations in linguistic category priming effects (IJzerman, Saddlemyer, & Koole, 2014). The authors conclude by highlighting the importance of conducting and publishing replication research for achieving scientific progress.

On the road to somewhere: Brain potentials reflect language effects on motion event perception

Recent studies have identified neural correlates of language effects on perception in static domains of experience such as colour and objects. The generalization of such effects to dynamic domains like motion events remains elusive. Here, we focus on grammatical differences between languages relevant for the description of motion events and their impact on visual scene perception. Two groups of native speakers of German or English were presented with animated videos featuring a dot travelling along a trajectory towards a geometrical shape (endpoint). English is a language with grammatical aspect in which attention is drawn to trajectory and endpoint of motion events equally. German, in contrast, is a non-aspect language which highlights endpoints. We tested the comparative perceptual saliency of trajectory and endpoint of motion events by presenting motion event animations (primes) followed by a picture symbolising the event (target): In 75% of trials, the animation was followed by a mismatching picture (both trajectory and endpoint were different); in 10% of trials, only the trajectory depicted in the picture matched the prime; in 10% of trials, only the endpoint matched the prime; and in 5% of trials both trajectory and endpoint were matching, which was the condition requiring a response from the participant. In Experiment 1 we recorded event-related brain potentials elicited by the picture in native speakers of German and native speakers of English. German participants exhibited a larger P3 wave in the endpoint match than the trajectory match condition, whereas English speakers showed no P3 amplitude difference between conditions. In Experiment 2 participants performed a behavioural motion matching task using the same stimuli as those used in Experiment 1. German and English participants did not differ in response times showing that motion event verbalisation cannot readily account for the difference in P3 amplitude found in the first experiment. We argue that, even in a non-verbal context, the grammatical properties of the native language and associated sentence-level patterns of event encoding influence motion event perception, such that attention is automatically drawn towards aspects highlighted by the grammar.
