Social relationships and groups: New insights on embodied and distributed cognition

csr600

Eliot’s intro and first section to his paper:

Human cognition mostly takes place in the context of other people. This is true in two ways. First, if we consider the immediate context of other people who are physically present, they may influence or even help constitute an individual’s cognition by providing information, agreeing or disagreeing, being part of a group decision-making process, etc. (Tollefsen, 2006 and Wegner, 1986). And as a broader context, the group memberships and socially defined identities that make each of us who we are (e.g. an American, a professor, a father) both motivate and potentially bias our cognition as we move through our lives. As Clancey (1997, p. 366) put it, the “overarching content of thought is not…[descriptions or symbolic representations of states of the world], but coordination of an identity” in a social context. If I sit alone in my office working on a paper for publication, my actions are nevertheless socially shaped, for they ultimately reflect socially defined identities and goals (e.g. to write an interesting paper; to win the approval of professional colleagues; to be a successful researcher; to earn a living for myself and my family). Indeed, a pure case of individual (nonsocial) cognition – cognition that is independent not only from immediate social influences but also from the individual’s network of social relationships, group memberships, and self-identities – is difficult to even imagine.

The field of social psychology has as its defining focus such social influences on individual cognition, affect, and behavior, in both forms (the immediate social context, and the larger web of relationships and identities that shape the individual). Thus, this special issue on situated/embodied/distributed perspectives on social cognition addresses issues that are central to the field of social psychology. For this reason it is interesting to note that these emerging perspectives have actually been introduced to the field only recently (e.g. Barsalou et al., 2003, Semin and Smith, 2002, Semin and Smith, in press and Smith and Semin, 2004) – as much as a decade or two after they were initially advanced within artificial intelligence and cognitive science (Brooks, 1986/1999, Clancey, 1997 and Clark, 1997). However, as argued elsewhere in more detail (Smith & Semin, 2004), despite its recent onset, the integration of situated/embodied/distributed perspectives with the substantive concerns of social psychology is likely to be extraordinarily fruitful, even revolutionary in many respects. The reason is that the merger of these new perspectives, which have mostly been applied to improve our understanding of individual cognition and adaptive behavior, and the emphasis of social psychology on the centrality of the social context of behavior, opens up new vistas for conceptual and theoretical exploration.

This article addresses the intersection of embodied and distributed cognition, a focus that holds special interest from the viewpoint of social psychology. We can conceptualize this intersection in three ways. The first point is simply what these perspectives have in common: both seek to extend our conception of cognition beyond information processing performed by the brain, to include the body and sensory-motor systems (embodied cognition) as well as other bodies and minds (distributed cognition). Second, the principle of embodiment has to date been applied mostly to understanding individual functioning (e.g. the role of motor representations in language comprehension). Adding a distributed cognition perspective suggests that embodiment also has implications beyond the level of the individual, for example with regard to interpersonal cooperation or relationships. Third, socially distributed cognition, such as group problem-solving, has mostly been conceptualized as involving abstract, amodal information processing. But adding the embodiment perspective calls attention to potential embodied influences on group interaction and collective cognition. In fact, it can be argued that an important function of embodiment is to externalize cognitive processes so they can influence and be influenced by others. For example, if someone looks puzzled and scratches his head when trying without success to solve a puzzle or retrieve some information from memory, it may cue others to jump in and offer suggestions or help. If cognition was disembodied – implemented purely by inner computation processes lacking any external signs – distributing cognition across a group of people would be much more difficult.

This paper will discuss two areas within the intersection of the embodiment principle and distributed cognition. First, there are embodied aspects of social relationships as well as of individual-level cognition, and some preliminary evidence is now available on this point. Second, we will examine some general properties of socially distributed cognition (e.g. group problem-solving) in comparison to individual-level cognition. Research in this area has only begun to examine embodiment effects, but we will suggest some relevant possibilities.

1. Embodiment of social relationships

The principle of embodiment has typically been applied in an effort to understand individual-level functioning. For example, research addresses how the physical properties of muscles and limbs ease demands for neural control in locomotion (e.g. Thelen & Smith, 1994) or how multimodal representations of concepts enable language comprehension (e.g. Barsalou, 1999). A broader look at the embodiment concept includes examination of how aspects of social functioning – specifically, social relationships – are signaled and regulated by embodied cues.

The most directly relevant framework for addressing this topic is the relational models theory developed by Fiske (2004), a cognitive anthropologist. Fiske holds that there are four fundamental types of social relationships. Communal sharing (CS) describes a relationship where people focus on what they have in common and share resources as needed; it is typically found between close kin, and among members of cohesive groups, clans, etc. Authority ranking (AR) describes relationships structured by ordered differences in power or status; they are typically found in workplaces and other hierarchical social institutions, and also in many cases between parents and children. Two other types of relationships are argued to be historically more recent developments, and we will have little to say about these. Equality matching (EM) describes equal sharing or tit-for-tat exchange relationships, and market pricing (MP) involves the exchange of goods using assigned values.

Fiske’s work (2004) includes detailed accounts, supported by anthropological evidence across numerous cultures, of the types of embodied cues that are associated with each of these four relationship types. Specifically, CS relationships are said to be embodied by sharing substances such as food, physical closeness and touch, and synchronized bodily movements; AR relationships are embodied by differences in size or vertical position in space. It is valuable to think of these embodiment hypotheses in terms of Barsalou’s (1999) Perceptual Symbol System model, which holds that conceptual knowledge is represented by abstracted and generalized perceptual experiences that can be simulated (partially re-enacted) in context-sensitive ways. Barsalou’s model goes beyond the idea that we use bodily metaphors for types of social relationships, holding instead that perceptual experiences of physical closeness or synchrony or of differences in size or height partially constitute our concepts of relational closeness or differences in power or authority.

Consciousness and the social mind

csr600

Here is the intro to Phil’s piece.

Emotion is a hot topic, getting hotter all the time. The reasons for this enthusiasm are various, but the growth of neuroscientific interest in the area surely ranks high among them. The same goes for another hot topic: social cognition. Within the last two decades, two subfields of neuroscience have emerged: affective neuroscience, the study of the neural mechanisms underlying emotion and emotional feeling; and social neuroscience, the study of the neural mechanisms underlying social cognition. The parallel development of these new brain sciences is no accident. As Damasio (1994) makes clear, emotional and social functioning are deeply intertwined, since practical rationality is scaffolded by the ability to feel one’s way through the world, the social world included. This is now a familiar theme in cognitive science. Less familiar is the idea that the link between emotional and social functioning identified by Damasio forms part of a constellation of connections between consciousness (in the phenomenal, ‘what it’s like’ sense; see Nagel, 1974) and social cognition. In this paper, I try to identify some of these other connections, and to explore their implications for how we think about the conscious mind in general.

The plan of the paper goes like this. In the first part, I argue that a wide swath of consciousness is a product of the social mind, as it arises from cognitive operations dedicated to processing information about the domain of persons. I begin by describing two phenomena that have attracted considerable attention in the empirical literature. The first is social pain: the affect associated with the perception of actual or potential damage to one’s interpersonal relations. The second phenomenon of interest is affective contagion: the tendency for emotions, moods, and other affective states to spread from person to person as a consequence of social perception. Neuroscientific investigation of these phenomena suggests that affective consciousness depends on perception of the social world in much the same way that it depends on perception of the body. It appears, in short, that consciousness is a ‘socially embodied’ capacity, in two senses of the term (articulated below). In the second part of the paper I look at the flip side of this thematic coin. Here I argue that the distinctive sociality of our species, especially its moral dimension, rests heavily on our ability to represent the conscious states of others. In closing, I try to connect the two main claims of the paper – the claim that consciousness is essentially social, and the claim that thinking about consciousness is socially essential – by showing how they jointly point to a kind of circular causal-mechanistic nexus between consciousness and social mindedness.

Functionalism and mental boundaries

csr600

I’ve decided to dust off some of the papers from a themed issue that I co-edited five years ago since I happen to be very much in “extended mind” mode just now. First up is Larry Shapiro – below is his into; here is his abstract.

1. Introduction

Where are minds? For most people the answer to this question is obvious: the mind is in the head. The tough questions about minds typically concern how the physical stuff in the head produces minds. Surprisingly, however, there is growing controversy among psychologists and philosophers over how to answer the first question I asked. Traditional cognitive scientists (henceforth cognitivists) continue to defend the obvious answer. Researchers in the area of extended cognition (henceforth extended cognitivists) have urged a different answer. According to extended cognitivists, the mind’s location is only partly in the head. In addition, extended cognitivists have argued, the mind is located in parts of the world outside the body.

Clearly there is much at stake in this dispute. If extended cognitivists are right, there is much about psychology that is wrong. Cognitive neuroscience, for instance, would have been grounded in the false belief that all cognitive processes emerge somehow from neural processes. Computational psychologists would have to look beyond the brain to specify in full the implementation of algorithmic processes that previously had been thought to occur only in the head. Studies of psychopathologies could not limit themselves to an investigation of brain disorders.

Moreover, the possibility of extended cognition suggests new lines of research within the domain of social cognition. If minds extend, the boundaries that define the units of social interaction become less certain. Perhaps minds overlap. If, as some extended cognitivists believe, features of the environment comprise parts of a cognitive system, then a single piece of the world might constitute a piece of distinct cognitive systems. More dramatically, perhaps parts of a mind of one individual may be located within the mind of another. Insofar as extended cognition can make such possibilities plausible, social psychologists will need to re-interpret the nature of social interaction, will need to re-examine how the motivations and emotions of a single agent can influence an extended cognitive system, and so on.

Perhaps more seriously, if minds are extended then our ordinary ways of describing and thinking about human beings must undergo dramatic revision. We might have to learn to make sense of claims like “Welch accidentally left his memory on the bus,” or “Dixon stubbed his mind on his way to work this morning.” To traditionalist ears, both these claims sound like category mistakes, as in this example from Gilbert Ryle: “she came home in a flood of tears and a sedan-chair” (1949, p. 22). Just as floods of tears and sedan-chairs belong to distinct logical categories whose combination is jarring, the re-conception of minds that extended cognition promotes is likely to strike many as at least unnerving and quite possibly incoherent.

Of course, the possibility of extended minds must rest on a theory of mind. By this I mean that talk of extended minds can make sense only given various assumptions about what minds are. For instance, if one thought that minds are identical to brains – that mental properties are identical to neural properties – then the claims of extended cognition could be rejected outright. Grounding extended cognition must be a theory of mind that is consistent with the possibility of extended minds. This point may make one wonder whether the dispute between cognitivists and extended cognitivists is in fact a dispute over theories of mind. If so, this would be disappointing. The controversy is interesting only insofar as its participants share a view about what minds are but disagree over how to draw the mind’s boundaries.

Fortunately, many involved in the dispute seem committed to a common theory of mind, viz. functionalism. From the perspective of functionalism, mental states are identical to particular functional roles. Agreement about this lets the controversy over extended cognition take place at the appropriate level: the dispute can now focus on where minds are given a common assumption about what minds are.

Unfortunately, or so I shall argue, functionalism is the wrong perspective from which to judge the merits of the extended cognition program. Indeed, commitment to functionalism makes arguments for or against extended cognition too easy. Consequently, the decision regarding the mind’s extent must take place against the backdrop of non-functionalist considerations.

In the first part of this chapter I show how functionalism has been used to support a case for extended cognition. I then consider an argument that tries to drive a wedge between functionalism and extended mind. Although this argument is compelling, I next present what I take to be a more significant barrier to those who use functionalism to motivate extended cognition. More specifically, I argue that functionalism is ill-equipped to answer a boundary problem that confronts decisions about the extent of a property’s realization. Because functionalism cannot solve the boundary problem, I conclude that any principled assessment of extended cognition must rest in part on non-functionalist grounds. Before starting on these tasks, however, I must say something about the content of functionalism.

Hayek’s Self-Organizing Mental Order and Folk-Psychological Theories of the Mind

310348_212776905458602_1873781576_n

The intro and conclusion to Chiara’s chapter:

Humans are social creatures and they deeply rely on mentalizing, which aims at understanding other people behaviors and formulating expectations about their future actions. The existence of inner mental states has been postulated to give an explanatory account of the observed behaviors of other individuals. In particular, the activation of theory of mind in social situations has been demonstrated by neuroeconomic and behavioral experiments such as: processes of market exchange and specialization of labor (Coricelli, McCabe, & Smith, 2000), decision-making involving strategic uncertainty, detection of social cheaters and, in general, cooperative games in which subjects need to predict their opponents’ strategies; these are all situations in which theory of mind1 is activated. Historically, two different models of mental processes have been considered in the literature about folk psychology: theory-theory and simulation-theory. Theory-theory posits that subjects who are attributing to others a particular mental state are applying a tacit piece of knowledge previously acquired ‘‘about what people feel, think, want, etc in given circumstances and how they will, therefore, act’’ (Perner, Gschaider, Kuhberger, & Schrofner, 1999). They basically own ‘‘folk theories’’ about others’ mental states and implicit causal laws about how the mind works. On the contrary, simulation theory posits that, in attributing mental states, subjects are not possessing tacitly codified knowledge, but they are rather running a simulation ‘‘putting themselves in others’ shoes.’’ Simulating means using one’s own mind as a model for other people’s mental states, while being unaware of this activity. Simulation directly bridges perception and action (Decety & Grezes, 2006). Hayek had already envisioned this relationship between sensory and motor activity (Hayek, 1952, p. 92) but he dwells more on a neuronal level explanation than a mental one.

Notwithstanding this historical opposition between theory and simulation, an approach that highlights their intermingling contributions and crossfertilizations has nowadays been favored (Goldman, 2006). This is the reason why, after introducing a brief sketch of these two positions, the paper focuses then on theory of mind broadly speaking as the capacity to share psychological states with others: this is the social cognitive capacity making humans collaborative and cooperative, able to be engaged in mutual coordinated actions and plans (Tomasello, 2005). Humans, as social actors, have to possess a cognitive machinery that makes them able to coordinate. This chapter investigates whether theory of mind can provide a plausible explanation, at the mind level, of the tacitly triggered process of knowledge coordination elaborated by Hayek. More specifically, does Hayek’s concept of coordinating and self-organizing orders imply a model of the mind that can be framed as the current philosophical concept of theory of mind? In particular, we address the question whether theory of mind can give an account of that ‘‘inter-personal’’ understanding of other people’s mental states that Hayek sketches without developing it in details (Hayek, 1952, p. 23).

The chapter is then structured as follow: second section frames the concept of mentalizing as it has been historically developed in theory-theory and simulation-theory; third section presents Hayek’s philosophical psychology, identifying specific issues to integrate the latter with modern theory of mind; it explains the roles of communication between individuals and the process of knowledge formation in Hayek’s view, trying to address the question why Hayek’s philosophical psychology does not properly consider the concept of ‘‘theory of mind.’’ Fourth section concludes with further ideas of comparison, presenting the concept of ‘‘social mind’’ from a neuroscientific perspective, considering the idea of mirror neurons.

Philosophical and experimental research in psychology has been centered on the social nature of the mind for the past 20 years. Imitation is an important aspect of social learning, even at the mental level: mental mimicry (Gallese & Goldman, 1998) is based on the capacity to imitate other people’s mental states and has been defined as a process of isomorphism between states of mind of different persons, according to which two persons feel the same state of mind just seeing the other person in a particular situation or understanding the other person’s mental state. A particular case of isomorphism is represented by empathy: this is an automatic process triggered by an affective state, elicited by the observation or imagination of another individual’s affective state. Empathy has been associated with both epistemological and social roles (De Vignemont & Singer, 2006): it provides knowledge of the environment around us, connecting emotional stimuli coming from the external environment, ‘‘their situative context’’ (ibid., p. 440), and the relationship between the empathizer and the target. Empathy has therefore a vivid social dimension.

Moreover, empathy has been advocated as one of the explanatory devices of altruistic and pro-social behaviors specific of human nature: justice and cooperation (Boyd & Richerson, 2006; Hoffman, 2000; Hume, 1739).

From a neuroscientific perspective, the ‘‘empathic’’ nature of the brain has been demonstrated by the existence of mirror neurons; in the second half of the Nineties a particular scientific discovery has been made in the macaque monkeys’ brain: mirror neurons (Gallese, Fatiga, Fogassi, & Rizzolatti, 1996; Rizzolatti, Fatiga, Gallese, & Fogassi, 1996). These are visuomotors neuronal cells that fire both during the individual execution of a goal-directed action and the observation of the same action in a target individuals. They are located in the so called area F5 of the brain that belongs to the ventral premotor cortex, and they are fundamental in developing a ‘‘motor-theory of social cognition’’ (Gallese, Keysers & Rizzolatti, 2004) since they completely change the philosophical basis of actions understanding: this means that with mirror neurons a direct link between ‘‘first and third person experience’’ (ibid., p. 396) is possible. Bridging first and third person, in particular, means connecting the ‘‘I do and I feel’’ experience with ‘‘he does and he feels’’ experience. This can occur, not on the basis of the visual representation and interpretation performed by a central system, but by the ‘‘penetration’’ of information related to the target into the neural system and knowledge of the observer, who is empathizing. The fact that the action perceived and registered by the mirror system is goal-directed is fundamental. In fact, in the original experiment on macaque monkeys (Umilta` et al., 2001), the mirror system is activated only when an action is explicitly directed towards an object: for instance, mirror neurons are firing both when the monkey is grasping an object and both when the monkey is looking at the experimenter grasping the same object. This happens in both a full vision and hidden conditions, that is, when both the object is present in the spatial vision of the animal and when it has been hidden beyond a sliding screen, but after being present. In contrast, mirror neurons do not fire when the object is not present from the beginning, and the grasping movement is directed toward nothing in particular. In this case, neither the full vision nor the hidden treatments are characterized by mirror neurons activation. This occurs because the action is perceived as not being goal-oriented.

More recent studies have shown that mirror neurons are present in human brain as well and that, moreover, they fire in response to a wider range of actions than the monkey system (Gallese et al., 2004). In particular, mirror neurons fire in humans in the case of facial expression recognition, because the observer tends to share the emotional and affective state of the target, demonstrating its understanding. Recognizing the powerful implications that the discovery of a mirror system in humans triggers, Gallese et al. (2004) propose a ‘‘unifying theory of social cognition’’ that is able to make sense of both first-person and third-person recognition and understanding of emotions and actions, both individually performed and observed in others: the understanding of social cognition implies a bridge ‘‘between others and ourselves’’ (Gallese et al., 2004, p. 400). Hayek himself highlights the relationship between perception and action developed by the mental order: in his opinion, the sensory representations of the environment are associated with a possible goal to be pursued in that environment through a movement pattern that will make the achievement of that goal possible. This process determines particular responses, suggesting possible corrections to be taken in the movement patterns if the first ones are not particularly successful. Hayek describes motor responses as directly belonging to the act of perception since they ‘‘serve for the proper evaluation of the stimulus’’ (Hayek, 1952, p. 92). The interaction between exteroceptive and proprioceptive impulses and the consequent feedbacks generate the processes of adaptation of the organism to the external environment, which are of particular significance for the elaboration of subjective knowledge. Hayek develops therefore a fundamental and modern theory about the mental order and its relationships with the physical and neuronal order, presenting in his ‘‘central thesis’’ the role of subjective knowledge created through a process of internal reconstruction and classification of external stimuli. It is precisely in connection with this specific point that the role of folk psychology may find its fruitful application in Hayek’s theory: folk psychology is the conceptual common sense framework that socialized subjects employ to interpret, understand and predict other subjects’ mental states and behaviors. Hayek believes that the fundamental operation that human mind can accomplish is classification. Beyond classification, we believe that mentalizing should be taken into consideration in order to give an account of the interpersonal and social dimensions of human life and human mind. In particular, of special interest for us, was to present an overview of current approaches in philosophy of mind, so to understand how the idea of folk psychology can be used as a tool to bridge Hayek’s theory of mental order toward an inter-personal conception of the mind, which Hayek himself seems to support, although never developing it in details.

Minds, Models and Milieux: Commemorating the Centenary of Herbert Simon’s Birth

Edited by Roger Frantz (San Diego State University) and Leslie Marsh (University of British Columbia)

Call for Papers

Herbert Simon (June 15, 1916 – February 9, 2001) was a polymath of the highest order, making significant contributions to sociology, political science, behavioral economics, epistemology, cognitive science, public administration, economics, organization theory and complexity studies. With ever narrowing specialization we may never (at least in our lifetime) see another intellect as genuinely polymathic as Simon. We take the view that Simon’s lifelong project is analogous to Adam Smith in the sense that just as Smith wrote about both Man’s inner life (Theory of Moral Sentiments) and his outer life (Wealth of Nations) so too did Simon in many of his publications. Our book will include chapters on Simon’s theory of mind, theory of rationality and his work on organizations and markets (the latter connoted by milieux of our tripartite title). We welcome proposals on all aspects of Simon’s work, be it his contribution to a single topic, a single field, or his interdisciplinary influence. Papers should include some – as long or as short as best befits your paper – historical perspective on Simon’s writings. What was the conventional wisdom on your paper’s topic when Simon undertook his research; what was Simon’s contribution to the topic and how did the change the conventional wisdom, if at all, and; how has his work influenced research in the field. Chapters dealing with some neglected aspect of Simon’s legacy would be welcome as well. The deadline for sending a proposal is May 1, 2013. We anticipate having the book published in 2016, the centenary of Simon’s birth.
