What are the affordances of artifacts? One view is that the affordances of artifacts, just as the affordances of natural objects, pertain to possible ways in which they can be manipulated. Another view maintains that, given that artifacts are sociocultural objects, their affordances pertain primarily to their culturally-derived function. Whereas some have tried to provide a unifying notion of affordance to capture both aspects, here I argue that they should be kept separate. In this paper, I introduce a distinction between (...) standard affordances, which concern the function of artifacts, and ad-hoc affordances, which refer to how artifacts are manipulated. I then argue for the neuropsychological plausibility of such a distinction, linking it to the dissociation between function knowledge and manipulation knowledge. Finally, I defend the equal status of these forms of knowledge and, hence, of standard and ad-hoc affordances, and I show that this has some implications for the debate on the role of motor processes in the conceptual knowledge of artifacts.

When faced with intertemporal choices, which have consequences that unfold over time, we often discount the future, preferring smaller immediate rewards often at the expense of long-term benefits. How psychologically connected one feels to one’s future self-influences such temporal discounting. Psychological connectedness consists in sharing psychological properties with past or future selves, but connectedness comes in degrees. If one feels that one is not psychologically connected to one’s future self, one views that self like a different person and is less (...) likely to wait for the future reward. Increasing perceived psychological connectedness to one’s future self may lead to more far-sighted decisions. Episodic prospection may help in this regard. Episodic prospection is our ability to ‘pre-experience’ the future by mentally simulating it, drawing on information from episodic memory and other sources. Episodic memory and prospection are thought to involve a special form of consciousness, which underpins the capacity to appreciate the connection between one’s past, present, and future selves. Simulating the future self through prospection may increase felt psychological connectedness and support future-oriented decision-making. Yet this is where a puzzle arises. The imagery of episodic memory and prospection is perspectival: often one views the visualised scenario from a detached perspective, seeing oneself from-the-outside as if viewing another person. The aim of this paper is to characterise how the perspectival imagery of prospection relates to psychological connectedness, and to show that even though such imagery involves a detached perspective it can still be used to help reward one’s future self.

Memory perspectives on past events allegedly take one of two shapes. In field memories, we recall episodes from a first-person point of view, while in observer memories, we look at a past scene from a third-person perspective. But this mere visuospatial dichotomy faces several practical and conceptual challenges. First, this binary distinction is not exhaustive. Second, this characterization insufficiently accounts for the phenomenology of observer memories. Third, the focus on the visual aspect of memory perspective neglects emotional, agential, and self-related (...) social aspects. Fourth, the focus on the time of recall neglects the fact that visual, emotional, agential, and social aspects of perspective can also be dissociated in the original experience. In this chapter, we move away from the standard visual dichotomy. Instead, we propose that memory perspective is better understood along four lines: visual, agential, emotional, and social. Drawing on empirical research, we argue that these dimensions predict a disposition to recall a past event based on the present situation of the memorizer. This account supports seeing episodic memory as a natural kind, supported by scenario construction mechanisms and minimal memory traces. By remapping the classic distinction between field and observer perspectives along four dimensions, our proposal provides explanatory advantages and secures practical gains by enabling testable hypotheses.

Time has been considered a crucial factor in distinguishing between two levels of self-awareness: the “core,” or “minimal self,” and the “extended,” or “narrative self.” Herein, I focus on this last concept of the self and, in particular, on the relationship between the narrative self and language. In opposition to the claim that the narrative self is a linguistic construction, my idea is that it is created by the functioning of mental time travel, that is, the faculty of human beings (...) to project themselves mentally backwards in time to relive, or forward to anticipate, events. Moreover, I propose that narrative language itself should be considered a product of a core brain network that includes mechanisms, such as mental time travel, mindreading, and visuo-spatial systems.

According to Chomsky, creativity is a critical property of human language, particularly the aspect of ?the creative use of language? concerning the appropriateness to a situation. How language can be creative but appropriate to a situation is an unsolvable mystery from the Chomskyan point of view. We propose that language appropriateness can be explained by considering the role of the human capacity for Mental Time Travel at its foundation, together with social and ecological intelligences within a triadic language-grounding system. Our (...) proposal is based on the change of perspective from the analysis of individual sentences to the flux of speech in which the temporal dimension of language is much more relevant. (shrink)

Contemporary semantic theories can be classified along two dimensions: (i) the way and time-course in which contextual factors influence sentence truth-conditions; and (ii) whether and to what extent comprehension involves sensory, motor and emotional processes. In order to explore this theoretical space, our ERP study investigates the time-course of the interaction between the lexically specified telic component of a noun (the function of the object to which the noun refers to, e.g., a funnel is generally used to pour liquids into (...) containers) and an ad-hoc affordance contextually induced by the situation described in the discourse. We found that, if preceded by a neutral discourse context, a verb incongruent with the noun’s telic component as in “She uses the funnel to hang her coat” elicited an enhanced N400 compared to a congruent verb as in “She uses the funnel to pour water into a container”. However, if the situation introduced in the preceding discourse induced a new function for the object as an ad-hoc affordance (e.g., the funnel is glued to the wall and the agent wants to hang the coat), we observed a crossing-over regarding the direction of the N400 effect: comparing the ad-hoc affordance-inducing context with the neutral context, the N400 for the incongruent verb was significantly reduced, whereas the N400 for the congruent verb was significantly enhanced. We explain these results as a consequence of the incorporation of the contextually triggered ad-hoc affordance into the meaning of the noun. Combining these results with an analysis of semantic similarity values between test sentences and contexts, we argue that one possibility is that the incorporation of an ad-hoc affordance may be explained on the basis of the mental simulation of concurrent motor information.

Models of discourse and narration elaborated within the classical compositional framework have been characterized as bottom-up models, according to which discourse analysis proceeds incrementally, from phrase and sentence local meaning to discourse global meaning. In this paper we will argue against these models. Assuming as a case study the issue of discourse coherence, we suggest that the assessment of coherence is a top-down process, in which the construction of a situational interpretation at the global meaning level guides local meaning analysis. (...) In support of our hypothesis, we explore the role of executive functions (brain functions involved in planning and organization of goal-oriented behaviors) in coherence’s establishment, discussing the results of several studies on narrative abilities of patients with brain injuries. We suggest that, compared to other models of discourse processing focused on comprehension, our model is a viable candidate for an integrated account of discourse comprehension and production.

Classical cognitive science has been characterized by an association with the computational theory of mind. Although this association has produced highly significant results, it has also limited the scope of scientific psychology. In this paper, we analyse the limits of the specific kind of computational model represented by the Chomskian-Fodorian tradition in the study of mind and language. In our opinion, the adhesion to the principle of formality imposed by this specific computational model has motivated the exclusion of consciousness in (...) the reflection on language and, consequently, has led to the inability to account for some aspects of language functioning at the processing level of discourse. The aim of this article is to restore the role of consciousness in discourse comprehension and production processes. Specifically, we argue that the ability to produce and understand discourses is based on individuals’ capacity for navigation in space and time. We will show that the space–time orientation is guaranteed by the projection of the self, which involves a special kind of consciousness. (shrink)

This study explores the relation between pain sensitivity and the cognitive processing of words. 130 participants evaluated the pain-relatedness of a total of 600 two-syllabic nouns, and subsequently reported on their own pain sensitivity. The results demonstrate that pain-sensitive people associate words more strongly with pain than less sensitive people. In particular, concrete nouns like ‘syringe’, ‘wound’, ‘knife’, and ‘cactus’ are considered to be more pain-related for those who are more pain-sensitive. These findings dovetail with recent studies suggesting that certain (...) bodily characteristics influence the way people form mental representations (Casasanto, 2009). We discuss three mechanisms which could potentially account for our findings: attention and memory bias, prototype analysis, and embodied cognition. We argue that, whereas none of these three accounts can be ruled out, the embodied cognition hypothesis provides a particularly promising view to accommodate our data. (shrink)

This study explores the relation between pain sensitivity and the cognitive processing of words. 130 participants evaluated the pain-relatedness of a total of 600 two-syllabic nouns, and subsequently reported on their own pain sensitivity. The results demonstrate that pain-sensitive people (based on their self-report) associate words more strongly with pain than less sensitive people. In particular, concrete nouns like syringe, wound, knife, and cactus, are considered to be more pain-related for those who are more pain-sensitive. We discuss our results in (...) the light of three theoretical frameworks – cognitive bias, prototype theory, embodied account. We argue that the latter is best suited to explain the results of this study in the sense in which it implies the principle of body specificity, according to which different bodily characteristics lead to corresponding differences in the way in which people construct concepts and word meanings.

We tend to seek immediate gratification at the expense of long-term reward. In fact, the more distant a reward is from the present moment?the more we tend to discount it. This phenomenon is known as temporal discounting. Engaging in mental time travel plausibly enables subjects to overcome temporal discounting, but it is unclear how, exactly, it does so. In this paper, we develop a framework designed to explain the effects of mental time travel on temporal discounting by showing how the (...) subject?s temporally extended self enables mental time travel to generate appropriate emotions that, in turn, via metacognitive monitoring and control, generate appropriate behaviours. Building on existing approaches we outline an initial framework, involving the concepts of emotion and the temporally extended self, to explain the effects of mental time travel on resisting temptation. We then show that this initial framework has difficulty explaining the effects of mental time travel on a closely related phenomenon, namely, overcoming procrastination. We next argue that, in order to explain these effects, the concept of emotion needs to be refined, and the concept of metacognition needs to be added to the framework: emotions involve an action-readiness component, which, through metacognitive monitoring and control, can enable the subject to resist temptation and overcome procrastination. Finally, we respond to an objection to our account?based on the somatic marker hypothesis?such that metacognition is not necessary to account for the role of emotions in decision-making. (shrink)

In the evolutionary theory, a central tenet is that complex forms evolved from simpler ones, according to a bottom-up process. When it comes to the evolution of language, however, a bottom-up approach is problematic. In this case, such an approach often assumes that minimal units that are inflexibly associated to their meaning come first, where the wider discourse is only a later product. In the present paper, I shall argue that we need to assume a top-down perspective on language evolution, (...) which claims that the wider discourse is the evolutionary starting point rather than the final achievement. This approach involves the necessity to focus on the pragmatic abilities of our ancestors and on the biological mechanisms underlying them. Combining a top-down model of language evolution with an embodied account of cognition, I shall argue that a basic mechanism of affordance perception supports core pragmatic processes by enabling the individual to determine not only her own action possibilities in the physical environment but also the action possibilities of others and, thereby, enabling her to determine other people’s intentions. As a result, I shall introduce the notion of an embodied pragmatics as a key to account for the evolution of language. (shrink)

L’indagine filosofica riserva da sempre grande attenzione alle questioni riguardanti la natura del linguaggio e della comunicazione. Recentemente, nel contesto della scienza cognitiva, sono stati avanzati tentativi esplicativi promettenti, sulla base di un assunto fondamentale: i modelli concettuali devono essere vincolati alla ricerca empirica. Il testo curato da Francesco Ferretti e Daniele Gambarara si fa portavoce di questa esigenza di dialogo tra scienza e filosofia, in opposizione ad un...
