The way in which abstract concepts are represented has recently become a topic of intense debate, especially because of the spread of the embodied approach to cognition. Within this framework concepts derive their meaning from the same perception, motor and emotional systems that are involved in online interaction with the world. Most of the evidence in favour of this view, however, has been gathered with regard to concrete concepts. Given the relevance of abstract concepts for higher-order cognition, we argue that being able to explain how they are represented is a crucial challenge that any theory of cognition needs to address. The aim of this article is to offer a critical review of the latest theories on abstract concepts, focusing on embodied ones. Starting with theories that question the distinction between abstract and concrete concepts, we review theories claiming that abstract concepts are grounded in metaphors, in situations and introspection, and in emotion. We then introduce multiple representation theories, according to which abstract concepts evoke both sensorimotor and linguistic information. We argue that the most promising approach is given by multiple representation views that combine an embodied perspective with the recognition of the importance of linguistic and social experience. We conclude by discussing whether or not a single theoretical framework might be able to explain all different varieties of abstract concepts.

In the view I will outline, instead, concepts correspond to patterns of activation of the perception, action and emotional systems which are typically activated when we interact with the entities they refer to. Starting from this embodied and grounded approach to concepts, I will focus on different research lines and present some experimental evidence concerning concepts of objects, concepts of actions, and abstract concepts. I will argue that, in order to account for abstract concepts, embodied and grounded theories should be extended.

In this paper, we will review recent studies performed in our lab (Body Action Language Lab, BALLAB) or in labs with which we collaborate, showing the involvement of the sensorimotor system at different levels. With the purpose of expounding on this aspect, we focus on studies that highlight two main characteristics of the involvement of the sensorimotor systems. First, we concentrate on the flexibility of sensorimotor grounding during interaction with objects. We report evidence showing how social context and current situations influence affordance activation. We then focus on the tactile and kinesthetic involvement in body-object interaction. Second, we illustrate flexible sensorimotor grounding in word use. We review studies showing that not only concrete words, like “bottle,” but also abstract words, like “freedom,” “thinking,” and “perhaps,” are grounded in the s...

However, evidence is controversial, also because different criteria were used to select abstract concepts – for example, imageability and abstractness were equated. In addition, for many years abstract concepts have been considered as a unitary whole. Our work aims to address these two limitations. We asked participants to evaluate 425 abstract concepts on 15 dimensions: abstractness, concreteness, imageability, context availability, Body-Object-Interaction, Modality of Acquisition, Age of Acquisition, Perceptual modality strength, Metacognition, Social metacognition, Interoception, Emotionality, Social valence, Hand and Mouth activation.

Being at the bridge between perception and action, affordances help to question a dichotomous view of perception and action. While Gibson's view of affordances is mainly externalist, many contemporary approaches define affordances (and micro-affordances) as the product of long-term visuomotor associations in the brain. These studies have emphasized the fact that affordances are activated automatically, independently from the context and the previous intention to act: for example, affordances related to objects' size would emerge even if the task does not require focusing on size. This emphasis on the automaticity of affordances has led to overlook their flexibility and contextual-dependency. In this contribution I will outline and discuss recent perspectives and evidence that reveal the flexibility and contextdependency of affordances, clarifying how they are modulated by the physical, cultural and social context. I will focus specifically on social affordances, i.e. on how perception of affordances might be influenced by the presence of multiple actors having different goals.

Here we assessed motor resonance during an action prediction task using transcranial magnetic stimulation to probe corticospinal excitability (CSE) and report that experimentally-induced updates in observers' prior expectations modulate CSE when predictions are made under situations of perceptual uncertainty. We show that prior expectations are updated on the basis of both biomechanical and probabilistic prior information and that the magnitude of the CSE modulation observed across participants is explained by the magnitude of change in their prior expectations. These findings provide the first evidence that when observers predict...

Recent findings demonstrate that also motor actions interact with number magnitude processing, showing a motor-to-semantic effect. The current study assesses whether calculation processes can be modulated by motions performed with the whole body. Participants were required to make additions or subtractions while performing (on-line condition) or after having experienced (off-line condition) an ascending or descending motion through a passive (i.e., taking the elevator) or an active (i.e., taking the stairs) mode. Results show a congruency effect between the type of calculation and the direction of the motion depending on: a) the off-line or on-line condition, b) the passive or active mode and c) the real or imagined task. Implications of the results for an embodied and grounded perspective view will be discussed.

Participants were asked to perform additions or subtractions while executing an ascending or descending movement in a passive (i.e., by taking the elevator) or active (i.e., by taking the stairs) mode. Results revealed a congruency effect between the type of calculation made and the direction of the movement performed, but only when participants experienced it through a passive mode. Our data are in line with studies providing evidence of a strict link between numerical and spatial representations, and between motor actions and number magnitude processing (motor-to-semantic effect). Implications of the results for the embodied and grounded nature of numerical cognition will be considered and discussed.

The aim of the present study was to scrutinize the role of the motor cortex in this process. We developed a new paradigm to study the abstract-concrete dimension by combining concrete (i.e. action-related) and abstract (i.e. non-action-related) verbs with nouns of graspable and non-graspable objects. Using these verb-noun combinations we performed a Transcranial Magnetic Stimulation (TMS) on the left primary motor cortex while participants performed a sentence sensibility task.

We claim that embodied views should be extended in order to consider not only language grounding but the social and normative aspects of language as well. Motor resonance mechanisms based on mirror neurons are a necessary but not sufficient component of this. We will argue that words cannot be conceived of as mere signals of something but also as tools that allows us to operate in the world. On this basis, we formulate a theoretical proposal that addresses one of the critical problems embodied views face: the problem of the so called "abstract concepts". Our proposal extends embodied views assuming two simultaneous cognitive sources for word meanings; an individual one, the embodied individual experience, and a socially embodied one.

We hypothesize that everyday interactions around objects are influenced by a minimal sense of object ownership grounded on respect of possession. In particular, we hypothesize that tracking object ownership can be influenced by any cue that predicts the establishment of individual physical control over objects. To test this hypothesis we used an indirect method to determine whether visual cues of physical control like spatial proximity to an object, temporal priority in seeing it, and touching it influence this minimal sense of object ownership. In Experiment 1 participants were shown a neutral object located on a table, in the reaching space of one of two characters. In Experiment 2 one character was the first to find the object then another character appeared and saw the object. In Experiments 3 and 4, spatial proximity, temporal priority, and touch are pitted against each other to assess their ...

This possibility stems from the embodied theory of language, according to which the linguistic system re-uses the structures of the motor system. The participants were presented with nouns of common tools preceded by a pair of verbs expressing grasping or observational motor chains (i.e., grasp-to-move, grasp-to-use, look-at-to-grasp, and look-at-to-stare). They decided whether the tool mentioned in the sentence was the same as that displayed in a picture presented shortly after. A primacy of the grasp-to-use motor chain over the other motor chains in priming the participants' performance was observed in both the experiments. More interestingly, we found that the motor information evoked by the noun was modulated by the specific motor-chain expressed by the preceding verbs. Specifically, with the grasping chain aimed at using the tool, the functional motor information prevailed over the volumetric information, and vice versa with the grasping chain aimed at moving the tool (Experiment 2). Instead, the functional and volumetric information were balanced for those motor chains that comprise at least an observational act (Experiment 1). Overall our results are in keeping with the embodied theory of language and suggest that understanding sentences expressing an action directed toward a tool drives a chained activation of the motor system.

It has been argued that this cognitive cost is the result of a perceptual simulation. This paper extends this argument and reports an experiment investigating whether the effect is the result of an activation of sensory information which can also be triggered by perceptual linguistically described stimuli. Participants were first exposed to a prime sentence describing a light or a sound's perceptual property (e.g., "The light is flickering", "The sound is echoing"), then required to perform a property-verification task on a target sentence (e.g., "Butter is yellowish", "Leaves rustle"). The content modalities of the prime and target sentences could be compatible (i.e., in the same modality: e.g., visual-visual) or not (i.e., in different modalities). Crucially, we manipulated the stimuli's presentation modality such that half of the participants was faced with written sentences while the other half was faced with aurally presented sentences. Results show a cost when two different modalities alternate, compared to when the same modality is repeated with both visual and aural stimuli presentations. This result supports the embodied and grounded cognition view which claims that conceptual knowledge is grounded into the perceptual system. Specifically, this evidence suggests that sensory modalities can be pre-activated through the simulation of either read or listened linguistic stimuli describing visual or acoustic perceptual properties.

Here, we sought to evaluate how an observer visually encodes tool-object affordances. Eye-movements were recorded as right-handed participants freely viewed static, right-handed, egocentric tool-object images across three contexts: correct (e.g. hammer-nail), incorrect (e.g. hammer-paper), spatial/ambiguous (e.g. hammer-wood), and three grasp-types: no hand, functional grasp-posture (grasp hammer-handle), non-functional/manipulative graspposture (grasp hammer-head). There were three areas of interests (AOI): the object (nail), the operant tool-end (hammer-head), the graspable tool-end (hammer-handle). Participants passively evaluated whether tool-object pairs were functionally correct/incorrect. Clustering of gaze scanpaths and AOI weightings grouped conditions into three distinct grasp-specific clusters, especially across correct and spatial tool-object contexts and to a lesser extent within the incorrect tool-object context. The grasp-specific gaze scanpath clusters were reasonably robust to the temporal order of gaze scanpaths. Gaze was therefore automatically primed to grasp-affordances though the task required evaluating tool-object context. Participants also primarily focused on the object and the operant tool-end and sparsely attended to the graspable tool-end, even in images with functional grasp-postures. In fact, in the absence of a grasp, the object was foveally weighted the most, indicative of a possible object-oriented action priming effect wherein the observer may be evaluating how the tool engages on the object. Unlike the functional grasp-posture, the manipulative grasp-posture caused the greatest disruption in the object-oriented priming effect, ostensibly as it does not afford tool-object action due to its non-functional interaction with the operant tool-end that actually engages with the object (e.g., hammer-head to nail). The enhanced attention towards the manipulative graspposture may serve to encode grasp-intent. Results here shed new light on how an observer gathers action-information when evaluating static tool-object scenes and reveal how contextual and grasp-specific affordances directly modulate visuospatial attention.

The enhanced attention towards the manipulative graspposture may serve to encode grasp-intent. Results here shed new light on how an observer gathers action-information when evaluating static tool-object scenes and reveal how contextual and grasp-specific affordances directly modulate visuospatial attention.

Si può parlare del linguaggio in astratto, senza considerare le differenze tra le lingue che parliamo? Si può parlare del pensiero in generale, senza parlare della diversità dei corpi e dei contesti in cui viviamo? In che modo il tipo di corpo che possediamo influenza il nostro modo di pensare, di conoscere, di parlare? Il nostro corpo è un'entità soltanto biologica o anche sociale? In che misura le lingue che parliamo influenzano il nostro modo di pensare? La tesi di questo libro è che non si possono studiare la mente e il linguaggio umani se non li si radica nell'esperienza corporea. Questo significa, però, che poiché questa esperienza non si dà se non in una situazione, in una cultura, entro una specifica forma di vita, non esiste qualcosa come la cognizione umana, o il linguaggio umano. Di qui l'enfasi che il libro pone, ed è la sua caratteristica più originale, sulla differenza tra linguaggio e lingue.
