The article discusses evolutionary aspects of mimicry from a semiotic viewpoint. The concept of semiotic scaffolding is used for this approach, and its relations with the concepts of exaptation and semiotic co-option are explained. Different dimensions of scaffolding are brought out as ontogenetic, evolutionary, physiological and cognitive. These dimensions allow for interpreting mimicry as a system that scaffolds itself. With the help of a number of mimicry cases, e.g. butterfly eyespots, brood parasitism, and plant mimesis, the (...) evolutionary dynamics of mimicry in the open bio-semiosphere is investigated. The main argument is that biological mimicry largely develops through sign relations and communicative relations between organisms. It is proposed that mimicry systems should be described as two-layered structures composed of the ecological composition of the species involved and the semiotic structure of their communication.

Practically all theories of iconicity are denunciations of its subject matter (for example, those of Goodman, Bierman and the early Eco). My own theory of iconicity was developed in order to save a particular kind of iconicity, pictoriality, from such criticism. In this interest, I distinguished pure iconicity, iconic ground, and iconic sign, on one hand, and primary and secondary iconic signs, on the other hand. Since then, however, several things have happened. The conceptual tools that I created to explain (...) pictoriality have been shown by others to be relevant to linguistic iconicity. On the other hand, semioticians with points of departure different from mine have identified mimicry as it is commonly found in the animal world as a species of iconicity. In the evolutionary semiotics of Deacon, iconicity is referred to in such a general way that it seems to be emptied of all content, while in the variety invented by Donald the term mimesis is used for a particular phase in the evolution of iconic meaning. The aim of this article is to consider to what extent the extension of iconicity theory to new domains will necessitate the development of new models. (shrink)

Despite decades of study, mimicry continues to inspire and challenge evolutionary biologists. This essay aims to assess recent conceptual frameworks for the study of mimicry and to examine the links between mimicry and related phenomena. Mimicry is defined here as similarity in appearance and/or behavior between a mimic and a model that provides a selective advantage to the mimic because it affects the behavior of a receiver causing it to misidentify the mimic, and that evolved (or (...) is maintained by selection) because of those effects. Mimics copy cues or signals that are already in use as part of a stable communication system, but offer misleading information to receivers. Mimicry overlaps, both conceptually and evolutionarily, with camouflage and perceptual exploitation but the overlap is only partial, which may create some confusion. Certain types of camouflage (e.g. masquerade) conform to the definition of mimicry, while others (e.g. background matching) are not considered mimicry because they prevent detection rather than recognition of the camouflaged animal. Mimicry, on the other hand, works by exploiting peculiarities of the receiver at higher stages of sensory processing involving recognition and classification of stimuli. Perceptual exploitation models of trait evolution are also closely related to mimicry, and sensory traps in particular may act as a precursor for true mimicry to evolve. The common thread through these diverse phenomena is deception of a receiver by a mimic. Thus receiver deception (i.e. perceptual error) emerges as a key characteristic of mimicry shared with some types of camouflage and perceptual exploitation. (shrink)

Defining biomimetics as the imitation of models, systems and elements of nature for the purpose to solve human complex problems, the essay considers some examples of that activity, like display technologies, and nanoscientific innovations. According to the literature on the subject, the further section of the article examines the possibility of giving a conceptual framework for biomimetic processes, starting from the observation of its current insufficient development both on the logical level and on a wider philosophical one. The fourth section (...) discusses the way through which an approach oriented to philosophical anthropology and recent perspectives on imitation can help us to understand this kind of phenomena at the intersection of human and animal fields. In the final sections, the text discusses the consequences of the biomimicry approach in the specific case of architecture and tries to draw some conclusions on the way an anthropology and an aesthetics of human mimicry and imitation can be re-shaped including biomimetics among their assumptions.

The essay explores the concept of interpretation in Freudian psychoanalysis as an act of reading. Freud understands the appearance of dreams and unconscious phantasies in analogy to the structure of perceptual images. On the one hand, he conceives of the patients’ verbal accounts of those images as a specific kind of ekphrasis. On the other hand, the images themselves are regarded as distorted versions of an underlying »dream text« rendering the fundamental desire that the images express and conceal at the (...) same time. The essay shows that the complex system of translations between different layers of text and image in Freud is based on the assumption that the dream images themselves can be analyzed as texts only mimicking the »natural« appearance of perceptions. Freud’s notion of the »rebus« is central to this discussion. The final part examines Freud’s reading of Michelangelo’s Moses statue in the church San Pietro in Vincoli in Rome. It demonstrates how the Freudian method of interpretation itself reduces the sculpture to a set of signs, making it perform a mimicry of textual systems. (shrink)

The evolutionary origins of deception and its functional role in our species is a major focus of research in the science of human origins. Several hypotheses have been proposed for its evolution, often packaged under either the Social Brain Hypothesis, which emphasizes the role that the evolution of our social systems may have played in scaffolding our cognitive traits, and the Foraging Brain Hypothesis, which emphasizes how changes in the human dietary niche were met with subsequent changes in cognition to (...) facilitate foraging of difficult-to-acquire foods. Despite substantive overlap, these hypotheses are often presented as competing schools of thought, and there have been few explicitly proposed theoretical links unifying the two. Utilizing cross-cultural data gathered from the Human Relations Area Files (HRAF), we identify numerous (n = 357) examples of the application of deception toward prey across 145 cultures. By comparing similar behaviors in nonhuman animals that utilize a hunting strategy known as aggressive mimicry, we suggest a potential pathway through which the evolution of deception may have taken place. Rather than deception evolving as a tactic for deceiving conspecifics, we suggest social applications of deception in humans could have evolved from an original context of directing these behaviors toward prey. We discuss this framework with regard to the evolution of other mental traits, including language, Theory of Mind, and empathy. (shrink)

The concept of biological mimicry is viewed as a ‘process of life’ theory rather than a ‘process of change’ theory—regardless of the historical interest and heuristic value of the subject for the study of evolution. Mimicry is a dynamic ecological system reflecting the possibilities for mutualism and parasitism created by a pre-established bipartite signal-based relationship between two organisms – a potential model and its signal receiver (potential operator). In a mimicry system agency and perception play (...) essential, interconnected roles. Mimicry thus describes emergent biologically meaningful relationships based on synergy, and is not an object-based theory. Biosemiotics offers a particularly valuable discipline for analysing the dynamics and nuances of mimicry systems, and can thus pave the way for a better and more complete understanding of how mimicry has evolved in the past, and how it might evolve in the future—presented here with special reference to the need for an integrated, ‘third way of evolution’ approach to biological relativity. A revised definition of mimicry is proposed. (shrink)

Mimicry has been an important topic for biology since the rise of the Darwinian theory of evolution. However. by its very narure mimicry is a sign process and the quest for understanding mimicry in biology has intrinsically always been a semiotic quest. In this paper various theories since Henry W. Bates will be examined to show how the concept of mimicry has been shifted from perceptual resemblance to a particular communicative structure. A concept of mimicry (...) will then be formulated which emphasizes its dynamic properties, and finally, mimicry will be considered in the framework of ecosemiotics. (shrink)

Mimicry is often cited as a compelling demonstration of the power of natural selection. By adopting signs of a protected model, mimics usually gain a reproductive advantage by minimising the likelihood of being preyed upon. Yet while natural selection plays a role in the evolution of mimicry, it can be doubted whether it fully explains it. Mimicry is mediated by the emergence of formally analogous patterns between unrelated organisms and by the fact that these patterns are meaningfully (...) perceived as similar. The perception of similarity is always perceiver-dependent. Similarities between for instance colours are psychophysical phenomena, and their existence is conditioned by an intimate interdependence between perceivers and perceptible reality. In this sense, mimicry is by its very nature dualistic. The analogy in form needed to establish a mimicry does not emerge out of the blue. It depends on the ecological context and the morphogenetic potential of a species. In our proposal, we take into account both the developmental generators of formally analogous structures and the perceptual and cognitive processes that lead to the emergence of mimicry. We show that some of the rather controversial and nowadays largely neglected ideas found in non-Anglo-Saxon literature on mimicry deserve closer attention. We suggest that the diversity of mimicry types is due to differences in variational properties of form-generating and perceptual systems among diverse groups of organisms. We also anticipate that processes studied within social psychology and emotion research probably take place, at least in a simplified form, also in non-human animals. Finally, we argue that these meaning-attributive processes underlie the functionality of mimicry. (shrink)

Biological mimicry can be considered as having a double-layered structure: there is a layer of ecological relations between species and there is a layer of semiotic relations of the sign. The present article demonstrates the limitations of triadic models and typologies of mimicry, as well as their lack of correspondence to mimicry as it actually occurs in nature. It is argued that more dynamical semiotic tools are needed to describe mimicry in a theoretically coherent way that (...) would at the same time allow comparative approach to various mimicry cases. For this a five-stage model of analysis is proposed, which incorporates classical mimicry theory, Jakob von Uexküll’s Umwelt-theory, as well as semiotic and communication analysis. This research model can be expressed in the form of five questions: 1) What is the formal structure of mimicry system? 2) What are the perceptual and effectual correspondences between the participants of mimicry? 3) What are the characteristics of resemblances? 4) How is the mimicry system regulated in ontogenetic and evolutionary processes? 5) How is the mimicry system related to human cultural processes? As a practical example of this semiotic methodology, brood parasitism between the common cuckoo Cuculus canorus and his frequent host species is examined. (shrink)

Adaptive immunity provides the unique ability to respond to a nearly infinite range of antigenic determinants. Given the inherent plasticity of the adaptive immune system, a series of tolerance mechanisms exist to reduce reactivity toward self. While this reduces the probability of autoimmunity, it also creates an important gap in adaptive immunity: the ability to recognize microbes that look like self. As a variety of microbes decorate themselves in self‐like carbohydrate antigens and tolerance reduces the ability of adaptive immunity (...) to react with self‐like structures, protection against molecular mimicry likely resides within the innate arm of immunity. In this review, we will explore the potential consequences of microbial molecular mimicry, including factors within innate immunity that appear to specifically target microbes expressing self‐like antigens, and therefore provide protection against molecular mimicry.

I propose a T‐cell receptor (TcR)‐based mechanism by which immunity mediates both “genetic self” and “microbial self” thereby, connecting microbiome disease with autoimmunity. The hypothesis is based on simple principles. First, TcR are selected to avoid strong cross‐reactivity with “self,” resulting in selection for a TcR repertoire mimicking “genetic self.” Second, evolution has selected for a “microbial self” that mimics “genetic self” so as to share tolerance. In consequence, our TcR repertoire also mimics microbiome antigenicity, providing a novel mechanism for (...) modulating tolerance to it. Also, the microbiome mimics the TcR repertoire, acting as a secondary immune system. I call this TcR‐microbiome mimicry “holoimmunity” to denote immune tolerance to the “holobiont self.” Logically, microbiome‐host mimicry means that autoimmunity directed at host antigens will also attack components of the microbiome, and conversely, an immunological attack on the microbiome may cross‐react with host antigens producing “holoautoimmunity.”.

Bodily mimicry often makes the mimickee have more positive feelings about the mimicker. Yet, little is known about the causes of mimicry’s social consequences. When people mimic each other’s bodily movements face to face, they can either adopt a mirrorwise perspective (moving in the same absolute direction) or an anatomical perspective (moving in the same direction relative to their own bodies). Mirrorwise mimicry maximizes visuo-spatial similarity between the mimicker and mimickee, whereas anatomical mimicry maximizes the similarity (...) in the states of their motor systems. To compare the social consequences of visuo-spatial and motoric similarity, we asked participants to converse with an embodied virtual agent (VIRTUO), who mimicked their head movements either mirrorwise, anatomically, or not at all. Compared to participants who were not mimicked, those who were mimicked mirrorwise tended to rate VIRTUO more positively, but those who were mimicked anatomically rated him more negatively. During face-to-face conversation, mirrorwise and anatomical mimicry have opposite social consequences. Results suggest that visuo-spatial similarity between mimicker and mimickee, not similarity in motor system activity, gives rise to the positive social effects of bodily mimicry. (shrink)

Natural mimicry is ubiquitous. Plants mimic animals, animals mimic plants, animals mimic each other and animals may even mimic counterfactual states that deceive or distract other animals. Almost all natural mimicry is based on iconicity which hence anchors it in real world resemblances. The vast majority of natural mimicry is done unconsciously but when humans mimic, they know what they are doing. As Merlin Donald suggest, mimicry may in fact have played a crucial role in the (...) emergence of the human condition, allowing new forms of cognition to emerge. Here it is suggested that the role played by mimicry may have involved the evolution of a capacity for metaphorical perception, where an object may not only be seen ‘as is’ but also ‘as if’ it was a functional mimic of something else. This new form of mimicry made possible new forms of communication, co-operation and creative engagement with the environment. Once these developed to the point where they produced symbolic systems and other cultural tools, the nature of human mimicry expanded radically. No longer anchored in resemblance, it became detached and qualitatively distinct from natural forms. The consequences of this detachment are now becoming clear. (shrink)

In the current opinion paper, we provide a comparative perspective on specific aspects of primate empathic abilities, with particular emphasis on the mirror neuron system associated with mouth/face actions and expression. Mouth and faces can be very salient communicative classes of stimuli that allow an observer access to the emotional and physiological content of other individuals. We thus describe patterns of activations of neural populations related to observation and execution of specific mouth actions and emotional facial expressions in some (...) species of monkeys and in humans. Particular attention is given to dynamics of face-to-face interactions in the early phases of development and to the differences in the anatomy of facial muscles among different species of primates. We hypothesize that increased complexity in social environments and patterns of social development have promoted specializations of facial musculature, behavioral repertoires related to production and recognition of facial emotional expression, and their neural correlates. In several primates, mirror circuits involving parietal-frontal regions, insular regions, cingulate cortices, and amygdala seem to support automatic forms of embodied empathy, which probably contribute to facial mimicry and behavioural synchrony. In humans these circuits interact with specific prefrontal and temporo-parietal cortical regions, which facilitates higher order cognitive functions such as cognitive empathy and mental state attribution. Our analysis thus suggests that the evolution of higher forms of empathy, such as mentalizing, is also linked to the coupling between the perceptual and motor system related to face processing, which may have undergone a process of exaptation during primate phylogeny.

The first clinical symptoms focused on the presentation of coronavirus disease 2019 have been respiratory failure, however, accumulating evidence also points to its presentation with neuropsychiatric symptoms, the exact mechanisms of which are not well known. By using a computational methodology, we aimed to explain the molecular paths of COVID-19 associated neuropsychiatric symptoms, based on the mimicry of the human protein interactions with SARS-CoV-2 proteins.Methods: Available 11 of the 29 SARS-CoV-2 proteins’ structures have been extracted from Protein Data Bank. (...) HMI-PRED, a recently developed web server for structural PREDiction of protein-protein interactions between host and any microbial species, was used to find the “interface mimicry” through which the microbial proteins hijack host binding surfaces. Classification of the found interactions was conducted using the PANTHER Classification System.Results: Predicted Human-SARS-CoV-2 protein interactions have been extensively compared with the literature. Based on the analysis of the molecular functions, cellular localizations and pathways related to human proteins, SARS-CoV-2 proteins are found to possibly interact with human proteins linked to synaptic vesicle trafficking, endocytosis, axonal transport, neurotransmission, growth factors, mitochondrial and blood-brain barrier elements, in addition to its peripheral interactions with proteins linked to thrombosis, inflammation and metabolic control.Conclusion: SARS-CoV-2-human protein interactions may lead to the development of delirium, psychosis, seizures, encephalitis, stroke, sensory impairments, peripheral nerve diseases, and autoimmune disorders. Our findings are also supported by the previous in vivo and in vitro studies from other viruses. Further in vivo and in vitro studies using the proteins that are pointed here, could pave new targets both for avoiding and reversing neuropsychiatric presentations. (shrink)

The starting point for studying the Croatian constitutional democracy is the adoption of the Constitution of the Republic of Croatia on 22 December 1990. The said Constitution defines the system of government as semi-presidential and its authors state as their model the Constitution of the Fifth Republic. However, the importing, in 1990, of French constitutional provisions was not neutral since the original French constitutional text was stripped of institutional obstacles, constitutional institutions for opposing the will of the President of (...) the Republic, constitutional-law conditions for the Prime Minister's primacy in the political system in case of co-habitation and discrepancies between the parliamentary and the presidential majority. The text was complemented by constitutional norms unknown to the original. French constitutional norms had to be put to good use, interpreted in line with and legally adapted to the desired political goal, i.e., the establishment of an effective state government in which the primacy of the President of the Republic would assert itself over both the Government and the legislature. The myth on the semi-presidential system was drawn on for both the adoption of the provisions regulating the organisation of government in the 1990 Constitution of the Republic of Croatia and their amendment in 2000.

This paper describes a study of the effects of two acts of social intelligence, namely mimicry and social praise, when used by an artificial social agent. An experiment ( N = 50) is described which shows that social praise—positive feedback about the ongoing conversation—increases the perceived friendliness of a chat-robot. Mimicry—displaying matching behavior—enhances the perceived intelligence of the robot. We advice designers to incorporate both mimicry and social praise when their system needs to function as a (...) social actor. Different ways of implementing mimicry and praise by artificial social actors in an ambient persuasive scenario are discussed. (shrink)

Ritualized behavior, intuitively recognizable by its stereotypy, rigidity, repetition, and apparent lack of rational motivation, is found in a variety of life conditions, customs, and everyday practices: in cultural rituals, whether religious or non-religious; in many children's complicated routines; in the pathology of obsessive-compulsive disorders (OCD); in normal adults around certain stages of the life-cycle, birthing in particular. Combining evidence from evolutionary anthropology, neuropsychology and neuroimaging, we propose an explanation of ritualized behavior in terms of an evolved Precaution System (...) geared to the detection of and reaction to inferred threats to fitness. This system, distinct from fear-systems geared to respond to manifest danger, includes a repertoire of clues for potential danger as well as a repertoire of species-typical precautions. In OCD pathology, this system does not supply a negative feedback to the appraisal of potential threats, resulting in doubts about the proper performance of precautions, and repetition of action. Also, anxiety levels focus the attention on low-level gestural units of behavior rather than on the goal-related higher-level units normally used in parsing the action-flow. Normally automatized actions are submitted to cognitive control. This “swamps” working memory, an effect of which is a temporary relief from intrusions but also their long-term strengthening. Normal activation of this Precaution System explains intrusions and ritual behaviors in normal adults. Gradual calibration of the system occurs through childhood rituals. Cultural mimicry of this system's normal input makes cultural rituals attention-grabbing and compelling. A number of empirical predictions follow from this synthetic model. (Published Online February 8 2007) Key Words: childhood ritual; compulsion; event boundaries; evolutionary psychology; obsessive-compulsive disorder; ritual; thought intrusion. (shrink)

No single theory so far proposed gives a wholly satisfactory account of the origin and maintenance of bird-song dialects. This failure is the consequence of a weak comparative literature that precludes careful comparisons among species or studies, and of the complexity of the issues involved. Complexity arises because dialects seem to bear upon a wide range of features in the life history of bird species. We give an account of the principal issues in bird-song dialects: evolution of vocal learning, experimental (...) findings on song ontogeny, dialect descriptions, female and male reactions to differences in dialect, and population genetics and dispersal.We present a synthetic theory of the origin and maintenance of song dialects, one that accommodates most of the different systems reported in the literature. The few data available suggest that large, regional dialect populations are genetically differentiated; this pattern is correlated with reduced dispersal between dialects, assortative mating by females, and male-male exclusion. At the same time, “subdialects” may be formed within regional dialects. Subdialect clusters are usually small and may represent vocal mimicry among a few adjacent territorial males. The relative importance of genetic and social adaptation may contribute to the emergence of subdialects; their distinctiveness may be correlated with the degree of polygyny, for example. Thus, subdialect formation is linked to one theory of the evolution of repertoire size, but data are too fragmentary to examine this idea critically. (shrink)

Appearance of Old world vipers of genus Vipera serves various purposes including crypsis and aposematism. Recent research showed that the zigzag pattern represents strong signal to predators to avoid vipers as a prey. It is also possible that vipers function within ecological community as Batesian model for numerous mimics, including other reptiles, birds, and invertebrates. It is then showed that Batesian models need to have prominent features to sustain the mimicry system. The main modulation of this system (...) is presented here as iconicity. Iconicity is treated as quantitative variable resulting from open dynamic process with multiple inputs, also including iconicity of previous states of system. Batesian mimicry is based on mimics adopting the iconicity of the model. It is an example of ecological facilitation, and as such, it is part of niche construction. Since Batesian mimicry is based on semiotic processes, it is a special case of ecological facilitation, namely semiotic facilitation. (shrink)

Recent application of theories of embodied or grounded cognition to the recognition and interpretation of facial expression of emotion has led to an explosion of research in psychology and the neurosciences. However, despite the accelerating number of reported findings, it remains unclear how the many component processes of emotion and their neural mechanisms actually support embodied simulation. Equally unclear is what triggers the use of embodied simulation versus perceptual or conceptual strategies in determining meaning. The present article integrates behavioral research (...) from social psychology with recent research in neurosciences in order to provide coherence to the extant and future research on this topic. The roles of several of the brain's reward systems, and the amygdala, somatosensory cortices, and motor centers are examined. These are then linked to behavioral and brain research on facial mimicry and eye gaze. Articulation of the mediators and moderators of facial mimicry and gaze are particularly useful in guiding interpretation of relevant findings from neurosciences. Finally, a model of the processing of the smile, the most complex of the facial expressions, is presented as a means to illustrate how to advance the application of theories of embodied cognition in the study of facial expression of emotion.

Mimicry and deception are two important issues in studies about animal communication. The reliability of animal signs and the problem of the benefits of deceiving in sign exchanges are interesting topics in the evolution of communication. In this paper, we intend to contribute to an understanding of deception by studying the case of aggressive signal mimicry in fireflies, investigated by James Lloyd. Firefly femmes fatales are specialized in mimicking the mating signals of other species of fireflies with the (...) purpose of attracting responding males to become their prey. These aggressive mimics are a major factor in the survival and reproduction of both prey and predator. It is a case of deception through active falsification of information that leads to efficient predation by femmes fatales fireflies and triggered evolutionary processes in their preys’ communicative behaviors. There are even nested coevolutionary interactions between these fireflies, leading to a remarkable system of deceptive and counterdeceptive signaling behaviors. We develop here a semiotic model of firefly deception and also consider ideas advanced by Lloyd about the evolution of communication, acknowledging that deception can be part of the explanation of why communication evolves towards increasing complexity. Increasingly complex sign exchanges between fireflies evolve in an extremely slow pace. Even if deceptive maneuvers are played out time and time again between particular firefly individuals, the evolution of the next level of complexity—and thus the next utterance in the dialogue between species—is likely to take an immense amount of generations.

Automatic imitation or “imitative compatibility” is thought to be mediated by the mirror neuron system and to be a laboratory model of the motor mimicry that occurs spontaneously in naturalistic social interaction. Imitative compatibility and spatial compatibility effects are known to depend on different stimulus dimensions—body movement topography and relative spatial position. However, it is not yet clear whether these two types of stimulus–response compatibility effect are mediated by the same or different cognitive processes. We present an interactive (...) activation model of imitative and spatial compatibility, based on a dual-route architecture, which substantiates the view they are mediated by processes of the same kind. The model, which is in many ways a standard application of the interactive activation approach, simulates all key results of a recent study by Catmur and Heyes (2011). Specifically, it captures the difference in the relative size of imitative and spatial compatibility effects; the lack of interaction when the imperative and irrelevant stimuli are presented simultaneously; the relative speed of responses in a quintile analysis when the imperative and irrelevant stimuli are presented simultaneously; and the different time courses of the compatibility effects when the imperative and irrelevant stimuli are presented asynchronously.

Synchronization is a special case of self-organization in which one can observe close mimicry in behavior of the system components. Synchrony in body movements, autonomic arousal, and EEG activity among human individuals has attracted considerable attention for their possible roles in social interaction. This article is specifically concerned with autonomic synchrony and finding the best model for the dyadic relationships, with regard to both theoretical and empirical accuracy, that could be extrapolated to synchrony levels for groups and teams (...) of three or more people. The four models that are compared in this study have different theoretical origins: the two-variable linear regression function, a three-parameter nonlinear regression function, the logistic map function stated in polynomial form, and the logistic map function stated as an exponential regression structure. The data for this study were electrodermal responses collected from a team of four people engaged in an emergency response simulation that produced 12 dyadic time series. Results shows strong levels of fit between the data and all four models, although there were significant differences among them. Further research directions point toward finding conditions that favor one model over another and exploring other possible nonlinear structures. (shrink)

Human communication is multi-modal. It is an empirical fact that many of our acts of communication exploit a variety of means to make our communicative intentions recognisable. Scholars readily distinguish between verbal and non-verbal means of communication, and very often they deal with them separately. So it is that a great number of semanticists and pragmaticists give verbal communication preferential treatment. The non-verbal aspects of an act of communication are treated as if they were not underlain by communicative intentions. They (...) are “relegated” to mere aspects of the context. However, several schools of thoughts have a different take on the issue. Thus psychologists or semioticians of gesture have shown how intricately gestures and speech are related in utterances. And, in a different area of the theoretical landscape, so-called “Relevance Theorists” have made the same point. Thus, Robyn Carston writes that “the domain of pragmatics is a natural class of environmental phenomena, that of ostensive stimuli; verbal utterances are the central case, but not the only one, and they themselves are frequently accompanied by other ostensive gestures of the face, hands, voice etc, all of which have to be interpreted together if one is to correctly infer what is being communicated”. This position rests on the assumption that there is a single “pragmatic system” or module at work in the interpretation of “ostensive stimuli”. When it comes to interpreting verbal stimuli, the same mechanisms and resources are used as when it comes to processing non-verbal ones. If there is no distinct “linguistic pragmatic system”, then the scholar who studies communication should not favour the verbal at the expense of the non-verbal. In this paper, I want to make a contribution to the study of multi-modal messages by considering a type of utterances that mix the verbal with the non-verbal in such a way that a piece of non-linguistic communication seems to stand in for a linguistic constituent which remains unrealised. Here is a real-life example : I didn't see the [IMITATION OF FRIGHTENING GRUMPINESS] woman today; will she be back this week? The square-bracketed string in small capitals is meant to capture the facial expressions and gestures performed in the conversational setting. What is intriguing here is that this instance of ostensive mimicry does not come as a mere complement to some linguistic stimulus; it appears to take the place of that stimulus. I shall try to show that a linguistic analysis can indeed be offered for cases like – though, I believe, without succumbing to the pro-linguistic bias that Carston warns against. I will, however, argue against an ellipsis-based account : the structure of sentence does not contain an unrealised adjective phrase. Instead, I shall defend a ‘syntactic-recruitment' account.

Ethological theories usually attribute semantic content to animal signals. To account for this fact, many biologists and philosophers appeal to some version of teleosemantics. However, this picture has recently came under attack: while mainstream teleosemantics assumes that representational systems must cooperate, some biologists and philosophers argue that in certain cases signaling can evolve within systems lacking common interest. In this paper I defend the standard view from this objection.

Here, I outline the idea of a unified hypothesis of sensory perception, developed from the theoretical vibrational mechanism of olfaction, which can be applied across all sensory modalities. I propose that all sensory perception is based upon the detection of mechanical forces at a cellular level, and the subsequent mechanotransduction of the signal via the nervous system. Thus, I argue that the sensory modalities found in the animal kingdom may all be viewed as being mechanoreceptory, rather than being discrete (...) neurophysiological systems which evolved independently of each other. I go on to argue that this idea could potentially explain language evolution, with birdsong being an example of a more simple form of non-Saussurean language that employs ‘frequency-mimicking’ to produce a vocal signal which describes acoustic, chemical and electromagnetic vibrational frequencies detected within in the environment. I also give examples of how this hypothesis could potentially explain phenomena such as vocal mimicry in animals, as well as the human perception of musicality and the occurrence of synaesthesia; a condition found in humans, where the stimulation of one sensory modality results in the stimulation of another. For example, auditory stimuli are detected and are heard as an acoustic signal, as well as being perceived as colour by the visual system. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Hypothesis on the Origin of TradeThe Exchange of Lives for Sacrifice and SexPablo Díaz-Morlán (bio)introductionThe primary objective of this study is to propose a hypothesis regarding the origin of trade that will help to solve the enigma of why human groups, normally each other's enemies, stopped exchanging blows in order to exchange things. The complexity of this crucial step forward in the relationships between hostile primitive groups can (...) be summarized as follows. In order for an exchange to take place, both parties must take part in it voluntarily because they see a mutual benefit in doing so. In turn, both parties should be aware that in order to obtain what interests them, which is closely guarded by the other party, in return, they must hand over what the other party is interested in. The perception of the interest of the other plays a crucial role in trade, both today and in its origins. The next step to be taken after a successful initial exchange was its consolidation, after it had been proved that it mutually benefited groups who had, until then, been enemies. Once established, this pacific exchange would have diversified considerably and its complexity would have increased significantly. An added [End Page 165] advantage, which was unexpected but real, was that its subsequent usefulness in curbing violence contributed to its growing expansion. The emergence of a comparative advantage in the groups that adopted trade would have guaranteed their future progress with respect to those that continued to systematically adopt violent conduct toward their neighbors.1Throughout this study, we will come across the old idea that the market prevents war. Without a doubt, trade and war between individuals and groups are closely connected, but the boundaries between them are fuzzy and their demarcation has proven elusive to researchers. Albert Hirschman studied the intellectual climate in the seventeenth and eighteenth centuries in favor of trade and the express declaration of Montesquieu that "peace is the natural effect of trade."2 Since then, this idea has gained ground among researchers of economics and other fields of knowledge. In L'enfer des choses and subsequent works, Jean-Pierre Dupuy and Paul Dumouchel defend that the economy (the market) is a substitute for the sacred, containing violence through violent means. The market contains violence in the two senses of the term contain: It holds it and curbs it; it is both the poison and the remedy. The consumer society makes all objects available to everyone and in this way deactivates mimetic rivalry, deferring violent conflicts. But it is only a temporary remedy. In the words of Girard, "It is always necessary to find new toys."3Following the path initiated by Dumouchel and Dupuy, with their criticism of the free market economy and their proposal for a new notion of scarcity, in his text The Empire of Value, André Orléan claims that money is at the origin of the market. My analysis alludes to a moment prior to that established by Orléan. He maintains that he does not contemplate the historical origin of money but instead uses the expression "the conceptual origin of money." In fact, when he defends the essential monetary base of the market, he refers to an already developed market system, that is, an economic system for which the operation is structured around the institution of the market.4 Mark R. Anspach also criticized the market system in his book À Charge de Revanche. This author proposes the transcending of the perverse logic of vengeance that defines both war and the market that transforms it into a positive reciprocity based on the gift. This constitutes a type of shift away from looking at the past (settling old accounts) to looking toward the future, embracing gratitude, which gives rise to the initial gesture of giving.5 This study analyzes a time prior to that examined by Orléan and Anspach. It was the moment of hominization, that is, mimicry, the subsequent violence that threatened the survival of human groups and, as we will seek to explain, the market as an institution that has accompanied humankind since its conformation as a species...

We suggest that supergenes, groups of co‐inherited loci, may be involved in a range of intriguing genetic and evolutionary phenomena in insect societies, and may play broad roles in the evolution of cooperation and conflict. Supergenes are central in the evolution of an array of traits including self‐incompatibility, mimicry, and sex chromosomes. Recently, researchers identified a large supergene, described as a social chromosome, which controls social organization in the fire ant. This system was previously considered to be a (...) remarkable example of a single gene affecting a complex social trait. We describe how selection may commonly favor reduced recombination and the formation of supergenes for social traits, and once formed, supergenes may strongly influence further evolutionary dynamics within and between lineages. The evolution of supergenes, and even wholly non‐recombining genomes, may be particularly common in systems in which genetically distinct lineages can form mutually reinforcing socially parasitic relationships.

This article considers the relationship between Christian pastoral care and Artificial Intelligence systems. Four aspects are identified from definitions of pastoral care: the horizon of contingency in mortality, the role of wisdom rather than mere information, the oppressive and/or liberatory potential of AI and the importance of empathic presence. In rejecting a transhumanist argument that mental processes are substrate-independent, it is contended that pastoral carers embrace, rather than seeking to circumvent, their crucial finitude in being humans who care. A distinction (...) is drawn between probabilistic reasoning and judgement in retaining a vital place for decision-making that is social. Whilst not eschewing value in AI systems, this article argues for critical evaluation of technologically framed contributions to addressing barriers to people's participation. The importance of empathy is highlighted—in the light of claims not only of robotic mimicry but of interindividual models of emotion. It is concluded that the notion of artificial care be ruled out although the possibilities of AI-assisted care are not dismissed. Opportunities for humans to abdicate from the responsibilities to care, in favour of AI substitutes, are deemed to be best avoided. (shrink)

Focusing on the spectacular propaganda exhibitions “Degenerate Art” and “Degenerate Music,” critical studies of Nazism's art policy long considered the regime's public attack on modernism and the turn to pseudo-classicism as decisive proof of Nazism's reactionary character. Studies such as Die Kunst im Dritten Reich , which inspired broader research on the topic in the early 1970s, subscribed to a modern conception of aesthetics in which art expresses complex systems of ideas in progress. Artistic style, from this perspective, corresponded to (...) political tendencies and reflected the traditional divide between conservatism and progressivism. But those boundaries have become blurred in the wake of more recent research, which has demonstrated the involvement of modernist artists in Nazi art and, conversely, the continual performance of popular jazz music in the Third Reich . Seen against such instances of modernist collaboration and its own occasional mimicry of modernism, National Socialism acquires a more ambivalent profile, characterized by the ongoing conflict between reactionary factions and those who favoured modernization for various reasons.

The goal of this article is to discuss theoretical arguments concerning the idea that emotional mimicry is an intrinsic part of our social being and thus can be considered a social act. For this, we will first present the theoretical assumptions underlying the Emotional Mimicry as Social Regulator view. We then provide a brief overview of recent developments in emotional mimicry research and specifically discuss new developments regarding the role of emotional mimicry in actual interactions and (...) relationships, and individual differences in emotional mimicry. We conclude with open questions for future research. (shrink)

Facial electromyography (EMG) was used to investigate patterns of facial mimicry in response to partial facial expressions in two contexts that differ in how naturalistic and socially significant the faces are. Experiment 1 presented participants with either the upper- or lower-half of facial expressions and used a forced-choice emotion categorisation task. This task emphasises cognition at the expense of ecological and social validity. Experiment 2 presented whole heads and expressions were occluded by clothing. Additionally, the emotion recognition task is (...) more open-ended. This context has greater social validity. We found mimicry in both experiments, however mimicry differed in terms of which emotions were mimicked and the extent to which the mimicry involved muscle sites that were not observed. In the more cognitive context, there was relatively more motor matching (i.e. mimicking only what was seen). In the more socially valid context, participants were less likely to mimic only what they saw – and instead mimicked what they knew. Additionally, participants mimicked anger in the cognitive context but not the social context. These findings suggest that mimicry involves multiple mechanisms and that the more social the context, the more likely it is to reflect a mechanism of social regulation. (shrink)

This commentary addresses emotional mimicry from a communication accommodation theory (CAT) perspective. After reviewing CAT, we outline commonalities between CAT and the Emotional Mimicry as Social Regulator view. We then discuss how CAT and the Emotional Mimicry as Social Regulator view can contribute to each other. Finally, we provide directions for future research on emotional mimicry informed by CAT, including ways to incorporate individual differences, listener-oriented perceptions, and variables relevant to families.

Changes in pupil size can reflect social interest or affect, and tend to get mimicked by observers during eye contact. Pupil mimicry has recently been observed in young infants, whereas it is unkno...

In their “social contextual view” of emotional mimicry, authors Hess and Fischer (2022) put forward emotional mimicry as a social regulator, considering it a social act, bound to certain affiliative contexts or goals. In this commentary, we argue that the core function of mimicry is to ease predicting conspecifics’ behaviours and the environment, and that as a consequence, this often smoothens social interactions. Accordingly, we make three main points. First, we argue that there is no good reason (...) to believe that the mimicry of negative expressions is fundamentally different than the mimicry of positive or ambiguous or autonomic expressions. Second, we give examples of empirical evidence that mimicry is not always a social act. Third, we show that mimicry has primary benefits for the mimicker. As such, we will briefly summarise and elaborate on the relevant findings in these respects, and propose a comparative, multi-method and ecologically valid approach which can explain the multifaceted character of the phenomenon.
