Mirror neurons and systems are often appealed to as mechanisms enabling mindreading, i.e., understanding other people’s mental states. Such neural mirroring processes are often treated as instances of mental simulation rather than folk psychological theorizing. I will call into question this assumed connection between mirroring and simulation, arguing that mirroring does not necessarily constitute mental simulation as specified by the simulation theory of mindreading. I begin by more precisely characterizing “mirroring” (Sect. 2) and “simulation” (Sect. 3). Mirroring results in a (...) neural process in an observer that resembles a neural process of the same type in the observed agent. Although simulation is often characterized in terms of resemblance (Goldman, Simulating minds: The philosophy, psychology, and neuroscience of mindreading, 2006), I argue that simulation requires more than mere interpersonal mental resemblance: A simulation must have the purpose or function of resembling its target (Sect. 3.1). Given that mirroring processes are generated automatically, I focus on what is required for a simulation to possess the function of resembling its target. In Sect. 3.2 I argue that this resemblance function, at least in the case of simulation-based mindreading, requires that a simulation serve as a representation or stand-in of what it resembles. With this revised account of simulation in hand, in Sect. 4 I show that the mirroring processes do not necessarily possess the representational function required of simulation. To do so I describe an account of goal attribution involving a motor mirroring process that should not be characterized as interpersonal mental simulation. I end in Sect. 5 by defending the conceptual distinction between mirroring and simulation, and discussing the implications of this argument for the kind of neuroscientific evidence required by simulation theory.

Several studies have reported impairment in the recognition of facial expressions of disgust in patients with Huntington's disease (HD) and preclinical carriers of the HD gene. The aim of this study was to establish whether impairment for disgust in HD patients extended to include the ability to express the emotion on their own faces. Eleven patients with HD, and 11 age and education matched healthy controls participated in three tasks concerned with the expression of emotions. One task assessed the spontaneous (...) production of disgust-like facial expressions during the smelling of offensive odorants. A second assessed the production of posed facial expressions during deliberate attempts to communicate emotion. The third task evaluated HD patients’ ability to imitate the specific facial configurations associated with each emotion. Foul odours induced fewer disgust-like facial reactions in HD patients than in controls, and patients’ posed facial expressions of disgust were less accurate than the posed disgust expressions of controls. The effect was selective to disgust; patients had no difficulty posing expressions of other emotions. These impairments were not explained by compromised muscle control: HD patients had no difficulty imitating the facial movements required to display disgust. Viewed together with evidence of difficulty in other aspects of disgust in HD, the findings suggest that a common substrate might participate in both the processing and the expression of this emotion.

We examine a prominent naturalistic line on the method of cases, exemplified by Timothy Williamson and Edouard Machery: MoC is given a fallibilist and non-exceptionalist treatment, accommodating moderate modal skepticism. But Gettier cases are in dispute: Williamson takes them to induce substantive philosophical knowledge; Machery claims that the ambitious use of MoC should be abandoned entirely. We defend an intermediate position. We offer an internal critique of Macherian pessimism about Gettier cases. Most crucially, we argue that Gettier cases needn’t exhibit (...) ‘disturbing characteristics’ that Machery posits to explain why philosophical cases induce dubious judgments. It follows, we show, that Machery’s central argument for the effective abandonment of MoC is undermined. Nevertheless, we engineer a restricted variant of the argument—in harmony with Williamsonian ideology–that survives our critique, potentially limiting philosophy’s scope for establishing especially ambitious modal theses, despite traditional MoC’s utility being partially preserved.

Single cell recordings in monkeys provide strong evidence for an important role of the motor system in action understanding. This evidence is backed up by data from studies of the (human) mirror neuron system using neuroimaging or TMS techniques, and behavioral experiments. Although the data acquired from single cell recordings are generally considered to be robust, several debates have shown that the interpretation of these data is far from straightforward. We will show that research based on single-cell recordings allows for (...) unlimited content attribution to mirror neurons. We will argue that a theoretical analysis of the mirroring process, combined with behavioral and brain studies, can provide the necessary limitations. A complexity analysis of the type of processing attributed to the mirror neuron system can help formulate restrictions on what mirroring is and what cognitive functions could, in principle, be explained by a mirror mechanism. We argue that processing at higher levels of abstraction needs assistance of non-mirroring processes to such an extent that subsuming the processes needed to infer goals from actions under the label ?mirroring? is not warranted.

Free will in intentional consciousness is exposed to skeptics since it was found that subconscious neural activities, what is called readiness potential, precedes the intention to an action. The question of whether free will is an authentic illusion has been argued not only in psychology but physics and philosophy. Most of scientists, however, think that the intentional consciousness who believes to have his/her own free will, is determined by readiness potential in advance, and that free will cannot coexist with determinism. (...) We here point out that knowing to be determined in advance cannot be verified till local event at a local site can be known from a different local site without disturbing the event. That is the assumption of locality. We here show that determinism, free will and locality are three essential elements in consciousness, and show that they constitute trilemma. The fact that one of three elements must be abandoned can lead to three types of consciousness. Absence of free will can constitute type I consciousness which is consistent with symptoms in autism spectrum disorder such as weakened theory of mind. Absence of determinism can constitute type II consciousness which is consistent with symptoms in schizophrenia such as thought insertion, self-other integration. Absence of locality can constitute type III consciousness which is consistent with typical people. We can find the entanglement of intentional consciousness with unconsciousness including readiness potential only in type III consciousness. Finally, we show that sense of agency and free will cannot be established until consciousness as an entanglement is implemented. (shrink)

The majority of contemporary models of wisdom define it in terms of a cognitive ability that is located in an agent’s mind. Even those models that include emotions, affective states, gut feelings etc. hardly recognise the relation between those non-cognitive dimensions, agents’ bodies and how they shape the content of experiences and how social practices of wisdom enfold. This paper will address this gap by providing a phenomenological account that depicts wisdom not as generated by wise individuals but as being (...) produced by and within embodied practices of agents relating to other people, artefacts, concepts, and ways of using others and things. It is argued that management should aim at building facilitative contexts that afford people to make use of and exploit the embodied dimension of wise practices. Exemplary strategies and tools that establish such sites, where embodied social practices of wisdom happen, are described. (shrink)

Recent studies of emotion mindreading reveal that for three emotions, fear, disgust, and anger, deficits in face-based recognition are paired with deficits in the production of the same emotion. What type of mindreading process would explain this pattern of paired deficits? The simulation approach and the theorizing approach are examined to determine their compatibility with the existing evidence. We conclude that the simulation approach offers the best explanation of the data. What computational steps might be used, however, in simulation-style emotion (...) detection? Four alternative models are explored: a generate-and-test model, a reverse simulation model, a variant of the reverse simulation model that employs an “as if” loop, and an unmediated resonance model.

In the second half of the twentieth-century, the traditional problem of other minds was re-focused on special problems with propositional attitudes and how we attribute them to others. How do ordinary people, with no education in scientific psychology, understand and ascribe such complex, unobservable states? In different terminology, how do they go about "interpreting" their peers?

Pierre Jacob (2008) raises several problems for the alleged link between mirroring and mindreading. This response argues that the best mirroring-mindreading thesis would claim that mirror processes cause, rather than constitute, selected acts of mindreading. Second, the best current evidence for mirror-based mindreading is not found in the motoric domain but in the domains of emotion and sensation, where the evidence (ignored by Jacob) is substantial. Finally, simulation theory should distinguish low-level simulation (mirroring) and high-level simulation (involving pretense or imagination). (...) Jacob implies that bi-level simulationism creates an unbridgeable 'gap' in intention reading, but this is not a compelling challenge. (shrink)

Theories of embodied cognition abound in the literature, but it is often unclear how to understand them. We offer several interpretations of embodiment, the most interesting being the thesis that mental representations in bodily formats (B-formats) have an important role in cognition. Potential B-formats include motoric, somatosensory, affective and interoceptive formats. The literature on mirroring and related phenomena provides support for a limited-scope version of embodied social cognition under the B-format interpretation. It is questionable, however, whether such a thesis can (...) be extended. We show the limits of embodiment in social cognition. (shrink)

Many current programs for cognitive science sail under the banner of “embodied cognition.” These programs typically seek to distance themselves from standard cognitive science. The present proposal for a conception of embodied cognition is less radical than most, indeed, quite compatible with many versions of traditional cognitive science. Its rationale is based on two elements, each of which is theoretically plausible and empirically well-founded. The first element invokes the idea of “bodily formats,” i.e., representational codes primarily utilized in forming interoceptive (...) or directive representations of one’s bodily states and activities. The second element appeals to wideranging evidence that the brain reuses or redeploys cognitive processes having different original uses. When the redeployment theme is applied to bodily formats of representation, they jointly provide for the possibility that body-coded cognition is a very pervasive sector of cognition. (shrink)

In recent years, scientists have increasingly taken to investigate the predictive nature of cognition. We argue that prediction relies on abstraction, and thus theories of predictive cognition need an explicit theory of abstract representation. We propose such a theory of the abstract representational capacities that allow humans to transcend the “here-and-now.” Consistent with the predictive cognition literature, we suggest that the representational substrates of the mind are built as ahierarchy, ranging from the concrete to the abstract; however, we argue that (...) there are qualitative differences between elements along this hierarchy, generating meaningful, often unacknowledged,diversity.Echoing views from philosophy, we suggest that the representational hierarchy can be parsed into:modality-specificrepresentations, instantiated on perceptual similarity;multimodalrepresentations, instantiated primarily on the discovery of spatiotemporal contiguity; andcategoricalrepresentations, instantiated primarily on social interaction. These elements serve as the building blocks ofcomplex structures discussed in cognitive psychology (e.g., episodes, scripts) and are the inputs for mental representations that behave like functions, typically discussed in linguistics (i.e.,predicators). We support our argument for representational diversity by explaining how the elements in our ontology are all required to account for humans’ predictive cognition (e.g., in subserving logic-based prediction; in optimizing the trade-off between accurate and detailed predictions) and by examining how the neuroscientific evidence coheres with our account. In doing so, we provide a testable model of the neural bases of conceptual cognition and highlight several important implications to research on self-projection, reinforcement learning, and predictive-processing models of psychopathology.

The aim of this article is to expand the diet of examples considered in philosophical discussions of imagination and pretense, and to offer some preliminary observations about what we might learn about the nature of imagination as a result. The article presents a number of cases involving imaginative contagion: cases where merely imagining or pretending that P has effects that we would expect only perceiving or believing that P to have. Examples are offered that involve visual imagery, motor imagery, fictional (...) emotions, and social priming. It is suggested that imaginative contagion is a more prevalent phenomenon than has typically been recognized. (shrink)

Social and neurocognitive research suggests that thinking about one’s own thinking and thinking about the thinking of others—termed ‘mindreading’, ‘metacognition’, ‘social cognition’ or ‘mentalizing’ are not identical activities. The ability though to think about thinking in the first person is nevertheless related to the ability to think about other’s thoughts in the third person. Unclear is how these phenomena influence one another. In this review, we explore how self-reflection and autobiographical memory influence the capacity to think about the thoughts and (...) emotions of others. We review studies suggesting that the more individuals are able to reflect on and retrieve episodes from their life narratives, the more they are likely to grasp others’ thoughts and emotions. We discuss evidence supporting this possibility including studies of the neurocognitive bases of empathy and self-awareness and how different aspects of self-reflection may impact on mindreading. We also draw from clinical reports how improved self-reflection may result in a more nuanced mindreading, namely persons suffering from schizophrenia and narcissistic personality disorder. We finally discuss the implications for research and practice and consider whether there are conditions in which the reverse is true, where self-reflection might impair mindreading or in which mindreading may facilitate self-reflection.

In this paper we address the epistemological debate between emerging perceptual accounts of knowing other minds and traditional theory of mind approaches to the problem of other minds. We argue that the current formulations of the debate are conceptually misleading and empirically unfounded. Rather, the real contribution of PA is to point out a certain ‘immediacy’ that characterizes episodes of mindreading. We claim that while the intuition of immediacy should be preserved for explaining the nature and function of some cognitive (...) processes of mindreading, the notion of immediacy should apply for describing a particular epistemic attitude and not a particular type of epistemic access. We draw on Wittgenstein's discussions of one's relation to other minds to elaborate our claims and to move the epistemological discussions beyond stalling debates between ToM and PA. (shrink)

This special issue targets two topics in social cognition that appear to increasingly structure the nature of interdisciplinary discourse but are themselves not very well understood. These are the notions of empathy and embodiment. Both have a history rooted in phenomenological philosophy and both have found extensive application in contemporary interdisciplinary theories of social cognition, at times to establish claims that are arguably contrary to the ones made by the phenomenologists credited with giving us these notions. But this special issue (...) is not about defending any philosophical tradition or theoretical stance against all others. It is about understanding some central aspects of the nature of our experience of other people. (shrink)

Simulation theories of social cognition abound in the literature, but it is often unclear what simulation means and how it works. The discovery of mirror neurons, responding both to action execution and observation, suggested an embodied approach to mental simulation. Over the last years this approach has been hotly debated and alternative accounts have been proposed. We discuss these accounts and argue that they fail to capture the uniqueness of embodied simulation (ES). ES theory provides a unitary account of basic (...) social cognition, demonstrating that people e their own mental states or processes represented with a bodily format in functionally attributing them to others.

Hidden away in the remote corners of one of the largest parts of Husserl's Kˆrper, if we can use that word to translate Corpus, there is ein Leib , an animate body of text that reverberates not only with some of Husserl's other little known texts, but also with some of the most recent discoveries in neuroscience. These texts suggest a theory of intersubjectivity, or what psychologists term social cognition. Let me start with a proviso: whether Husserl ever fully settled (...) on this theory is completely open to interpretation. Accordingly, I will leave it to Husserlian scholars to determine whether this is a position that Husserl actually or ultimately embraces, either in the years 1906 through 1913 when he writes some of these texts, or later when he writes other related texts. The texts in question are from Husserl's early years and they are rather tentative and reactive in nature, since he was just beginning to think of these problems, and he was responding to proposals put forward by Lipps and Meinung. That's also why I claim that these texts suggest a theory of social cognition rather than anything like a pure phenomenology of intersubjectivity. Husserl was trying to work out ways to counter the theories of Lipps and Meinung, and his reflections, I think, should count as phenomenologically informed theory. (shrink)

The representational dynamics of the brain is a subsymbolic process, and it has to be conceived as an "agent-free" type of dynamical self-organization. However, in generating a coherent internal world-model, the brain decomposes target space in a certain way. In doing so, it defines an "ontology": to have an ontology is to interpret a world. In this paper we argue that the brain, viewed as a representational system aimed at interpreting the world, possesses an ontology too. It decomposes target space (...) in a way that exhibits certain invariances, which in turn are functionally significant. A challenge for empirical research is to determine which are the functional regularities guiding this decomposition process. What are the explicit and implicit assumptions about the structure of reality, which at the same time shape the causal profile of the brain's motor output and the representational deep structure of the conscious mind arising from it (its "phenomenal output")? How do they constrain high-level phenomena like conscious experience, the emergence of a first-person perspective, or social cognition? By reviewing a series of neuroscientific results, we focus on the contribution the motor system makes to this process. As it turns out, the motor system constructs goals, actions, and intending selves as basic constituents of the world it interprets. It does so by assigning a single, unified causal role to them. Empirical evidence now clearly shows how the brain actually codes movements and action goals in terms of multimodal representations of organism-object relations. Under a representationalist analysis, this process can be interpreted as an internal representation of the intentionality relation itself. We try to show how such a more complex form of representational content, once it is in place, can later function as the building block for social cognition and a for more complex, consciously experienced representation of the first-person perspective as well. The motor system may therefore play a decisive role in understanding how the functional ontology of the human brain could be gradually extended into the subjective and social domains. (shrink)

ArgumentA number of theorists have proposed simulation theories of empathy. A review of these theories shows that, despite the fact that one version of the simulation theory can avoid a number of problems associated with such approaches, there are further reasons to doubt whether simulation actually explains empathy. A high-level simulation account of empathy, distinguished from the simulation theory of mindreading, can avoid problems associated with low-level (neural) simulationist accounts; but it fails to adequately address two other problems: the diversity (...) problem and the starting problem. It is argued that a narrative approach to empathy obviates all these problems and offers a more parsimonious account. (shrink)

The same neural structures involved in the unconscious modeling of our acting body in space also contribute to our awareness of the lived body and of the objects that the world contains. Neuroscientific research also shows that there are neural mechanisms mediating between the multi-level personal experience we entertain of our lived body, and the implicit certainties we simultaneously hold about others. Such personal and body-related experiential knowledge enables us to understand the actions performed by others, and to directly decode (...) the emotions and sensations they experience. A common functional mechanism is at the basis of both body awareness and basic forms of social understanding: embodied simulation. It will be shown that the present proposal is consistent with some of the perspectives offered by phenomenology. (shrink)

The paper first gives a conceptual distinction of the first, second and third person perspectives in social cognition research and connects them to the major present theories of understanding others (simulation, interaction and theory theory). It then argues for a foundational role of second person interactions for the development of social perspectives. To support this thesis, the paper analyzes in detail how infants, in particular through triangular interactions with persons and objects, expand their understanding of perspectives and arrive at a (...) self–other metaperspective. This allows them to grasp the other’s as well as their own perspective as such, which is equivalent to an explicit third person perspective and to an explicit first person perspective or self-consciousness. The paper describes the major steps towards these perspectives, pointing to a close interdependence of both developments. It argues that embodied second person interactions are not only an enabling, but the constitutive condition for the development of an explicit first and third person perspective. (shrink)

According to sensorimotor theory perceiving is a bodily skill involving exercise of an implicit know-how of the systematic ways that sensations change as a result of potential movements, that is, of sensorimotor contingencies. The theory has been most successfully applied to vision and touch, while perceptual modalities that rely less on overt exploration of the environment have not received as much attention. In addition, most research has focused on philosophically grounding the theory and on psychologically elucidating sensorimotor laws, but the (...) theory’s ramifications for neuroscience still remain underexamined. Here we sketch the beginnings of a research program that could address these two outstanding challenges in terms of auditory perception. We review the neuroscience literature on passive listening, which is defined as listening without overt bodily movement, and conclude that sensorimotor theory provides a unique perspective on the consistent finding of motor system activation. In contrast to competing theories, this activation is predicted to be involved not only in the perception of speech- and action-related sounds, but in auditory perception in general. More specifically, we propose that the auditory processing associated with supplementary motor areas forms part of the neural basis of the exercise of sensorimotor know-how: these areas’ recognized role in facilitating spontaneous motor responses to sound and supporting flexible engagement of sensorimotor processes to guide auditory experience and enable auditory imagery, can be understood in terms of two key characteristics of sensorimotor interaction, its “alerting capacity” and “corporality”, respectively. We also highlight that there is more to the inside of the body than the brain: there is an opportunity to develop sensorimotor theory into new directions in terms of the still poorly understood active processes of the peripheral auditory system.

Carruthers considers and rejects a mixed position according to which we have interpretative access to unconscious thoughts, but introspective access to conscious ones. I argue that this is too hasty. Given a two-level view of the mind, we can, and should, accept the mixed position, and we can do so without positing additional introspective mechanisms beyond those Carruthers already recognizes.

The New Neurophilosophy: An Introduction to the ANTW special issue Contemporary neurophilosophy is more pragmatic than the early neurophilosophy of the 1980’s. It features two implicit ideas: First, commonsense cognitive concepts (CCC’s) like ‘free will’, ‘thoughts’, ‘consciousness’, ‘attention’ and ‘self’, belong to a variety of disciplines and cannot be appropriated by either philosophy or cognitive neuroscience. Second, the description of biological processes in the brain and the description of behavioral processes by CCC’s are so far removed from each other that (...) a simple reduction, or even a relation of implementation between them, is implausible. What is needed instead, is a relation of interpretation: which cognitive concepts should be used to describe specific brain processes is not fixed in advance but the outcome of an ongoing negotiation between common sense practice, philosophy, and cognitive neuroscience. All articles in this special issue shed light on these two key ideas that characterize a new neurophilosophy. (shrink)

The evolutionary claim that the function of self-awareness lies, at least in part, in the benefits of theory of mind (TOM) regained attention in light of current findings in cognitive neuroscience, including mirror neuron research. Although certain non-human primates most likely possess mirror self-recognition skills, we claim that they lack the introspective abilities that are crucial for human-like TOM. Primate research on TOM skills such as emotional recognition, seeing versus knowing and ignorance versus knowing are discussed. Based upon current findings (...) in cognitive neuroscience, we provide evidence in favor of an introspection-based simulation theory account of human mindreading. (shrink)

A leading theoretical framework for naturalistic explanation of mind holds that we explain the mind by positing progressively "stupider" capacities ("homunculi") until the mind is "discharged" by means of capacities that are not intelligent at all. The so-called homuncular fallacy involves violating this procedure by positing the same capacities at subpersonal levels. I argue that the homuncular fallacy is not a fallacy, and that modern-day homunculi are idle posits. I propose an alternative view of what naturalism requires that reflects how (...) the cognitive sciences are actually integrating mind and matter. (shrink)

Recent accounts of mindreading—i.e., the human capacity to attribute mental states to interpret, explain, and predict behavior—have suggested that it has evolved through cultural rather than biological evolution. Although these accounts describe the role of culture in the ontogenetic development of mindreading, they neglect the question of the cultural origins of mindreading in human prehistory. We discuss four possible models of this, distinguished by the role they posit for culture: the standard evolutionary psychology model, the individualist empiricist model, the cultural (...) empiricist model, and the radical socio-cultural constructivist model, which we favor. We motivate model by arguing that many forms of mental state ascription do not serve the function of simply describing inner states causally responsible for the behavior of a cognitive agent; rather, they relate the agent to her environment by characterizing her practical commitments. Making these practical commitments explicit has an important regulatory function in that it supports action coordination and alignment on joint goals. We propose a model of how the ascription of mental states may have evolved as a linguistic device to perform exactly this function of making agents’ practical commitments explicit. (shrink)

The explosive growth over the last two decades of neuroscience, cognitive science, and “consciousness studies” as generally conceived, remains as yet unaccompanied by a corresponding development in the establishment of an explicitly semiotic understanding of how the relations of sign exchange at the neuronal level function in the larger network of psychologically accessible sign exchange. This article attempts a preliminary foray into the establishment of just such a neurosemiotic. It takes, as its test case and as its point of departure, (...) recent discoveries from the neurobiological research on viuso-motor transformations and on the widespread cortical phenomena of selectively tuned, single-neuron response to argue for a vision of “intersubjectivity” whereby the ens rationis arising as a function of the neuronal semiosphere may be abstracted, constructed, and shared mutually across agents.

This article focuses on the question of the function of imitation and whether current accounts of imitative function are consistent with our knowledge about imitation's origins. We first review theories of imitative origin concluding that empirical evidence suggests that imitation arises from domain‐general learning mechanisms. Next, we lay out a selective account of function that allows normative functions to be ascribed to learned behaviours. We then describe and review four accounts of the function of imitation before evaluating the relationship between (...) the claim that imitation arises out of domain‐general learning mechanisms and theories of the function of imitation.

Traditionally, theories of mindreading have focused on the representation of beliefs and desires. However, decades of social psychology and social neuroscience have shown that, in addition to reasoning about beliefs and desires, human beings also use representations of character traits to predict and interpret behavior. While a few recent accounts have attempted to accommodate these findings, they have not succeeded in explaining the relation between trait attribution and belief-desire reasoning. On my account, character-trait attribution is part of a hierarchical system (...) for action prediction, and serves to inform hypotheses about agents’ beliefs and desires, which are in turn used to predict and interpret behavior.

Reports of phantom limbs amongst aplasics have often been presented as evidence that body image is ‘hard-wired’ in the brain and that neither sensory input nor proprioceptive feedback are essential to its formation. Although attempts have been made to account for these phantoms by other means, these have been on a case by case basis and no satisfactory alternative framework has been proposed. This paper collates the accounts of aplasic phantoms and presents them as compatible with a four-part hypothesis, in (...) which body image is learnt from experience during both pre- and post-natal development, and in which cross-cortical connections and mirror neurons play prominent roles. This model unites several previously disparate theories to offer a viable solution to several longstanding phantom limb mysteries and serves to highlight avenues worthy of further inquiry. (shrink)

We tested the hypothesis that our ability to detect fine kinematics variations is tuned to reveal more subtle differences when the motion pattern belongs to the observer compared to another individual. To this purpose, we analyzed the responses of 15 subjects in a same-different task on pairs of movements, which could belong to one or two different subjects. Self vs. Other comparisons were obtained by presenting both the observer’s and another participant’s kinematics. Subjects responded faster and more accurately when they (...) observed their own gestures compared to movements of another participant. In the latter case, slight kinematic differences were more likely to remain undetected. These findings are discussed within an ecological framework: in observing others, we are more concerned with detection of goals and intentions, i.e., outstanding variations in motion patterns. Conversely, in self-observation detection of more subtle differences is required to facilitate learning and optimization of motor acts. (shrink)
