Language is assumed to affect memory by offering an additional medium of encoding visual stimuli. Given that natural languages differ, cross-linguistic differences might impact memory processes. We investigate the role of motion verbs on memory for motion events in speakers of English, which preferentially encodes manner in motion verbs (e.g., driving), and Greek, which tends to encode path of motion in verbs (e.g., entering). Participants viewed a series of motion events and we later assessed their memory of the path and manner of the original events. There were no effects of language-specific biases on memory when participants watched events in silence; both English and Greek speakers remembered paths better than manners of motion. Moreover, even when motion verbs were available (either produced by or heard by the participants), they affected memory similarly regardless of the participants' language: path verbs attenuated memory for manners of motion, but the reverse did not occur. We conclude that overt language affects motion memory, but these effects interact with underlying, shared biases in how viewers represent motion events.

Does language influence how we perceive the world? This study examines how linguistic encoding of relational information by means of verbs implicitly affects visual processing, by measuring perceptual judgements behaviourally, and visual perception and attention in EEG. Verbal systems can vary cross-linguistically: Dutch uses posture verbs to describe inanimate object configurations (the bottle stands/lies on the table). In English, however, such use of posture verbs is rare (the bottle is on the table). Using this test case, we ask (1) whether previously attested language-perception interactions extend to more complex domains, and (2) whether differences in linguistic usage probabilities affect perception. We report three nonverbal experiments in which Dutch and English participants performed a picture-matching task. Prime and target pictures contained object configurations (e.g., a bottle on a table); in the critical condition, prime and target showed a mismatch in object position (standing/lying). In both language groups, we found similar responses, suggesting that probabilistic differences in linguistic encoding of relational information do not affect perception.

Modern approaches to the Whorfian linguistic relativity question have reframed it from one of whether language shapes our thinking or not, to one that tries to understand the factors that contribute to the extent and nature of any observable influence of language on perception. The current paper demonstrates that such understanding is significantly enhanced by moving the evidentiary basis toward a more biologically grounded empirical arena. We review recent neuroscientific evidence using a variety of methodological techniques that reveal the functional organisation and temporal distribution of the ubiquitous relationship between language and cognitive processing in the human brain.

Grounded theories hold sensorimotor activation is critical to language processing. Such theories have focused predominantly on the dominant senses of sight and hearing. Relatively fewer studies have assessed mental simulation within touch, taste, and smell, even though they are critically implicated in communication for important domains, such as health and wellbeing. We review work that sheds light on whether perceptual activation from lesser studied modalities contribute to meaning in language. We critically evaluate data from behavioural, imaging, and cross-cultural studies. We conclude that evidence for sensorimotor simulation in touch, taste, and smell is weak. Comprehending language related to these senses may instead rely on simulation of emotion, as well as crossmodal simulation of the "higher" senses of vision and audition. Overall, the data suggest the need for a refinement of embodiment theories, as not all sensory modalities provide equally strong evidence for mental simulation.

ABSTRACT The role that language plays in shaping non-linguistic cognitive and perceptual systems has been the subject of much theoretical and experimental attention over the past half-century. Understanding how language interacts with non-linguistic systems can provide insight into broader constraints on cognitive and brain organization. The papers that form this volume investigate various ways in which linguistic structure can interact with and influence how speakers think about and perceive the world, and the related issue of the constraints that in turn shape linguistic representations. These theoretical and empirical contributions support deeper understanding of the interactions between language, thought, and perception, and motivate new approaches for developing directional predictions at both the neural and cognitive levels.

Knowledge of the world is fundamental to human thought and ability to navigate the world, and a large literature has accumulated on the neuroscience of semantic memory. Because language serves as one of the most important interfaces between the private world of thought and other people, researchers often tap into semantic memory through word-based tasks. But this approach fails to acknowledge crucial distinctions between word meaning and general-purpose, non-linguistic knowledge. This article will discuss the relation between words and non-linguistic representations, drawing in part on evidence about cross-linguistic lexical diversity. It will argue that a more nuanced consideration of the language-thought interface is needed in the neuroscience of concepts.

Colour naming across languages has traditionally been held to reflect the structure of colour perception. At the same time, it has often, and increasingly, been suggested that colour naming may be shaped by patterns of communicative need. However, much remains unknown about the factors involved in communicative need, how need interacts with perception, and how this interaction may shape colour naming. Here, we engage these open questions by building on general information-theoretic principles. We present a systematic evaluation of several factors that may reflect need, and that have been proposed in the literature: capacity constraints, linguistic usage, and the visual environment. Our analysis suggests that communicative need in colour naming is reflected more directly by capacity constraints and linguistic usage than it is by the statistics of the visual environment.
