When subjects view stimulation of a rubber hand while feeling congruent stimulation of their own hand, they may come to feel that the rubber hand is part of their own body. This illusion of body ownership is termed ‘Rubber Hand Illusion’ . We investigated sensitivity of RHI to spatial mismatches between visual and somatic experience. We compared the effects of spatial mismatch between the stimulation of the two hands, and equivalent mismatches between the postures of the two hands. We created (...) the mismatch either by adjusting stimulation or posture of the subject’s hand, or, in a separate group of subjects, by adjusting stimulation or posture of the rubber hand. The matching processes underlying body ownership were asymmetrical. The illusion survived small changes in the subject’s hand posture, but disappeared when the same posture transformations were applied to the rubber hand. Mismatch between the stimulation delivered to the subject’s hand and the rubber hand abolished the illusion. The combination of these two situations is of particular interest. When the subject’s hand posture was slightly different from the rubber hand posture, the RHI remained as long as stimulation of the two hands was congruent in a hand-centred spatial reference frame, even though the altered posture of the subject’s hand meant that stimulation was incongruent in external space. Conversely, the RHI was reduced when the stimulation was incongruent in hand-centred space but congruent in external space. We conclude that the visual–tactile correlation that causes the RHI is computed within a hand-centred frame of reference, which is updated with changes in body posture. Current sensory evidence about what is ‘me’ is interpreted with respect to a prior mental body representation. (shrink)

We studied how people determine when they are in control of objects. In a computer task, participants moved a virtual boat towards a goal using a joystick to investigate how subjective control is shaped by (1) correspondence between motor actions and the visual consequences of those actions, and (2) attainment of higher-level goals. In Experiment 1, random discrepancies from joystick input (noise) decreased judgments of control (JoCs), but discrepancies that brought the boat closer to the goal and increased success (the (...) autopilot) increased JoCs. In Experiment 2, participants raced to the goal against a computer-controlled rival boat while varying levels of noise interfered with each boat. Participants reached the goal more often and rated their own control higher when the computer rival had good control. Subjective control over moving objects depends partly on consistency between motor actions and their effects, but is also modulated by perceived success and competition. -/- Keywords: Control; Action; Feedback; Competition .

Previous research has demonstrated that self-involvement enhances the memorability of information encountered in the past. The emergence of this effect, however, is dependent on guided evaluative processing and the explicit association of items with self. It remains to be seen, therefore, whether self-memory effects would emerge in task contexts characterized by incidental-encoding and minimal self-involvement. Integrating insights from work on source monitoring and action recognition, we hypothesized that the effects of self-involvement on memory function may be moderated by the extent (...) to which encoding experiences entail volitional processing. The results of three experiments supported this prediction. Despite the adoption of an incidental task context and stimulus materials that were inconsequential to participants, the act of selection enhanced the memorability and accessibility of information. The implications of these findings for contemporary treatments of self are considered. (shrink)

Patients suffering from delusions of thought insertion (TI) report that external agents of different nature have placed thoughts into their minds. The symptom involves distressing feelings of intromission and exposition, loss of mental privacy, diminished ego boundaries, and a – often neglected – peculiar “physicality”. A dominant approach within cognitive sciences characterizes TI as involving alterations in the experience of being the author of certain thoughts. For the advocates of this so-called Standard Approach to TI, the absence of a sense (...) of agency for certain thoughts would lead to their externalization, this explaining the general structure of the clinical reports. In this paper, I problematize the phenomenological picture of everyday thoughts that the standard approach adopts when trying to make sense of TI. I claim that the standard approach neglects two more fundamental aspects of TI, namely the multimodal nature of thinking in psychosis and the deeply social dimension of the phenomenology of delusions in schizophrenia. After this, a broader descriptive phenomenological characterization of TI is provided. Finally, I establish some connections between the characterization of TI developed here and current research in social perception and clinical practice. (shrink)

In African philosophical literature, and especially in Afro-communitarianism, there are discussions about the value of the relationship an individual has with her respective community. By community, reference is made to the metaphysical holistic view of community which includes all beings in nature. But since the article deals with gender, which is a social construction, most of the arguments appeal to a narrower version of community, that of human beings. Therefore, discussions about “value” refer to the value that is given to (...) the relationship that surpasses any individual value, and it applies or appeals to human beings. One implication of this understanding and the prioritisation of the relationship is that identity is something that is conferred by this sort of relationship. In this article, we argue that this way of understanding “identity” from an Afro-communitarian world view has something to offer in understanding or conceptualising gender(ed) identity(ies). The assumption is that gender identity will be understood as socially conferred and most importantly, one that takes community as essential. (shrink)

We review the distinction between sense of agency and sense of ownership, and then explore these concepts, and their reflective attributions, in schizophrenic symptoms and agoraphobia. We show how the underlying dynamics of these experiences are different across these disorders. We argue that these concepts are complex and cannot be reduced to neural mechanisms, but involve embodied and situated processes that include the physical and social environments. We conclude by arguing that the subjective and intersubjective dimensions of agency and ownership (...) cannot be considered in isolation from one another, but instead form an interdependent pairing.

Today, avatars often represent users in digital worlds such as in video games or workplace applications. Avatars embody the user and perform their actions in these artificial environments. As a result, users sometimes develop the feeling that their self merges with their avatar. The user realizes that they are the avatar, but the avatar is also the user—meaning that avatar’s appearance, character, and actions also affect their self. In the present paper, we first introduce the event-coding approach of the self (...) and then argue based on the reviewed literature on human-avatar interaction that a self-controlled avatar can lead to avatar-self merging: the user sets their own goals in the virtual environment, plans and executes the avatar’s actions, and compares the predicted with the actual motion outcomes of the avatar. This makes the user feel body ownership and agency over the avatar’s action. Following the event-coding account, avatar-self merging should not be seen as an all-or-nothing process, but rather as a continuous process to which various factors contribute, including successfully taking the perspective of the avatar. Against this background, we discuss affective, cognitive, and visuo-spatial perspective taking of the avatar. As evidence for avatar-self merging, we present findings showing that when users take the avatar’s perspective, they can show spontaneous behavioral tendencies that run counter to their own.

The distinction between phenomenal and access consciousness is central to debates about consciousness and its neural correlates. However, this distinction has often been limited to the domain of perceptual experiences. On the basis of dream phenomenology and neuroscientific findings this paper suggests a theoretical framework which extends this distinction to dreaming, also in terms of plausible neural correlates. In this framework, phenomenal consciousness is involved in both waking perception and dreaming, whereas access consciousness is weakened, but not fully eliminated, during (...) dreaming. However, access consciousness is more active during lucid dreaming. The proposed framework accounts for different aspects of dream phenomenology, including levels of integration of perceptual, cognitive and affective features in dreams, bizarreness, dream amnesia and the occurrence of meta-awareness and accessibility in lucid dreaming. Self-related experiences and their neural substrates are suggested to be differently involved in waking cognition and dreaming. Further, phenomenal consciousness during both waking and dream experiences involve widespread recurrent interactions and convergence-divergence zones in the thalamo-cortico-limbic system, activated before conscious access in global workspace areas. Finally, we discuss the relationships of the proposed framework with other neurocognitive theories and models of consciousness and major theories of dreaming, and propose novel experimental predictions.

Which is my body and how do I distinguish it from the bodies of others, or from objects in the surrounding environment? The perception of our own body and more particularly our sense of body ownership is taken for granted. Nevertheless experimental findings from body ownership illusions (BOIs), show that under specific multisensory conditions, we can experience artificial body parts or fake bodies as our own body parts or body respectively. The aim of the present paper is to discuss how (...) and why BOIs are induced. We review several experimental findings concerning the spatial, temporal and semantic principles of crossmodal stimuli that have been applied to induce BOIs. On the basis of these principles, we discuss theoretical approaches concerning the underlying mechanism of BOIs. We propose a conceptualization based on Bayesian causal inference for addressing how our nervous system could infer whether an object belongs to our own body, using multisensory, sensorimotor and semantic information, and we discuss how this can account for several experimental findings. Finally, we point to neural network models as an implementational framework within which the computational problem behind BOIs could be addressed in the future. (shrink)

Floridi’s infosphere consisting of informational reality is estimated and delineated by introducing the new notion of Typ-Ken, an undifferentiated amalgam of type and token that can be expressed as either type or token dependent on contingent ontological commitment. First, we elaborate Floridi’s system, level of abstraction (LoA), model, and structure scheme, which is proposed to reconcile ontic with epistemic structural reality, and obtain the duality of type and token inherited in the relationship between LoA and model. While we focus on (...) the ontological commitment that can negotiate and emphasize the discrepancy between type and token, we show that most research focusing on different hierarchical layers (type and token) has converged onto the flattened perspective of type and token to clarify the role of ontological commitment. We propose the idea of Typ-Ken to avoid this flattening. In addition, we elaborate Taddeo and Floridi’s criticism of approaches to the symbol grounding problem and show that their criticism based on the zero semantical commitment condition is specific to the agents affected by the flattening. We then take bird flocks as a metaphor for the living infosphere as if it had one mind. The knowledge recently yielded by image analysis indicates that it is difficult for previous flock models based on agents equipped with the flattening of local (token) and global (type) to show the special feature of a flock of the scale-free proportion (SFP). We show here that agents based on the Typ-Ken can reveal the SFP, which is the essential characteristic of the living infosphere. In other words, Typ-Ken is an expression for informational reality (LoA and model with ontological commitment) that can reveal seamless local and global interactions in the functioning of a flock or infosphere.

Muselmannwas a term used in German concentration camps to describe prisoners near death due to exhaustion, starvation, and helplessness. This paper suggests that the inhuman conditions in the concentration camps resulted in the development of a defensive sense of disownership toward the entire body. The body, in such cases, is reduced to a pure object. However, in the case of theMuselmannthis body-as-object is felt to belong to the captors, and as such is therefore identified as a tool to inflict suffering (...) and pain on theMuselmannhimself. In this situation, lacking cognitive resources, theMuselmannmay have no other alternative than to treat his body as an enemy, and then to retreat or disinvest from the body. This response is a form of somatic apathy, an indifference that is tied to a loss of the self/non-self distinction. This may, in turn, lead to suicidal inclinations, even after liberation from the camp. (shrink)

A dominant view in contemporary cognitive neuroscience is that low-level, comparator-based mechanisms of motor control produce a distinctive experience often called the feeling of agency . An opposing view is that comparator-based motor control is largely non-conscious and not associated with any particular type of distinctive phenomenology . In this paper, I critically evaluate the nature of the empirical evidence researchers commonly take to support FoA-hypothesis. The aim of this paper is not only to scrutinize the FoA-hypothesis and data supposed (...) to support it; it is equally to argue that experimentalists supporting the FoA-hypothesis fail to establish that the experimental outcomes are more probable given the FoA-hypothesis than given the simpler hypothesis.

The phenomenology of controlled action depends on comparisons between predicted and actually perceived sensory feedback called action-effects. We investigated if intervening task-irrelevant but semantically related information influences monitoring processes that give rise to a sense of control. Participants judged whether a moving box “obeyed” or “disobeyed” their own arrow keystrokes or visual cues representing the computer’s choices . During 1 s delays between keystrokes/cues and box movements, participants vocalized directions cued by letters inside the box. Congruency of cued vocalizations was (...) manipulated relative to previously selected keystrokes and upcoming box movements. In Experiment 1, reported obey moves and feelings of control reflected the true frequency of obey moves, but were also modulated by vocalizations. Incongruent vocalizations reduced reported obey moves, whereas congruent vocalizations increased them. In Experiment 2, vocalizations had stronger effects when their congruence with primary-task box movement was consistent for several consecutive moves before congruence changed. In Experiment 3, analogous impacts of vocalizations occurred when the computer selected the directions and participants judged whether the computer had control of the box. We conclude that predicted and perceived action-effects associated with semantically related but separate and ostensibly irrelevant actions can be conflated with one another. This interference is not restricted to actions performed with the same effector or within the same modality, or even by the same actor. Thus in estimating degrees of control, the mind integrates across ongoing action systems, whether or not they are logically task-relevant. (shrink)

This paper seeks to describe and analyze the traumatic experience through an examination of the sense of agency—the sense of controlling one’s body, and sense of ownership—the sense that it is my body that undergoes experiences. It appears that there exist two levels of traumatic experience: on the first level one loses the sense of agency but retains the sense of ownership, whilst on the second one loses both of these, with symptoms becoming progressively more severe. A comparison of the (...) traumatic experience with various modulations of the senses of agency and ownership, from cases involving prostheses to tools requiring greater or lesser extents of control, suggests that the harsher the traumatic event, the greater the damage is to the sense of ownership, resulting in the increasing sense of the body as a tool rather than an original organism. Likewise, the long-term ramifications become more severe according to the significance of the damage to the sense of ownership. (shrink)

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

Previous studies have suggested that auditory hallucination is closely related to thought insertion. In this study, we investigated the relationship between the external misattribution of thought and auditory hallucination-like experiences. We used the AHES-17, which measures auditory hallucination-like experiences in normal, healthy people, and the Deese–Roediger–McDermott paradigm, in which false alarms of critical lure are regarded as spontaneous external misattribution of thought. We found that critical lures elicited increased the number of false alarms as AHES-17 scores increased and that scores (...) of AHES-17 predicted the rate of false memory of critical lures. Furthermore, we revealed that the relationship between AHES-17 scores and the rates of false alarms to critical lures was strictly linear. Therefore, it might be said that individual differences in auditory hallucination-like experiences are highly related to the external misattribution of thought. We discussed these results from the perspective of the sense of agency over thought. (shrink)

We challenge Gallagher’s distinction between the sense of ownership and the sense of agency as two separable modalities of experience of the minimal self and argue that a careful investigation of the examples provided to promote this distinction in fact reveals that SO and SA are intimately related and modulate each other. We propose a way to differentiate between the various notions of SO and SA that are currently used interchangeably in the debate, and suggest a more gradual reading of (...) the two that allows for various blends of SO and SA. Such an approach not only provides us with a richer phenomenology but also with a more parsimonious view of the minimal self. (shrink)

Developments in neurotechnology took a leap forward with the demonstration of the first Brain to Brain Interface (BBI). BBIs enable direct communication between two brains via a Brain Computer Interface (BCI) and bypasses the peripheral nervous system. This discovery promises new possibilities for future battlefield technology. As battlefield technology evolves, it is more likely to place greater demands on future soldiers. Future soldiers are more likely to process large amounts of data derived from an extensive networks of humans and machines. (...) This raises several ethical and philosophical concerns. This paper will look at BBI technology in current stages of research, future BBI applications in the military and how the potential use of BBIs in military operations challenges the way we understand the concept of responsibility. In this paper, I propose that an individual connected to a BBI ought not to be held fully responsible for her actions. The justification for this proposition is based on three key points such as an individual connected to a BBI does not have the ability to act freely, has a diminished sense of self-agency and may not be able to demonstrate authenticity of the thoughts and memories generated when connected to the interface.

Epidemiological studies have shown that environmental green space contributes to the reduction of psychosis incidence in the population. Clarifying the psychological and neuro-functional mechanisms underlying the risk-decreasing effects of green surroundings could help optimize preventive environmental interventions. This perspective article specifically aims to open a new window on the link between environmental green space and psychosis by considering its core psychopathological features. Psychotic disorders, such as schizophrenia, are essentially characterized by self-disturbances. The psychological structure of the self has been described (...) as a multidimensional phenomenon that emerges from the reciprocal interaction with the environment through intrinsic and extrinsic self-processes. The intrinsic self refers to the experience of mental activity and environmental information as inherently related to one’s own person, which involves self-referential processing, self-reflection, memory, interoception, and emotional evaluation. The extrinsic self refers to sensorimotor interactions with the environment and the sense of agency, that is, the experience of being the source of one’s own actions and the multisensory consequences thereof. In psychosis, anomalous self-processing has been related to a functional fragmentation of intrinsic and extrinsic self-processes and related brain networks. Moreover, evidence from cognitive neuroscience suggests that green space could have beneficial effects on self-related processing. Based on the literature, it could be hypothesized that self-processing is involved in mediating the beneficial effects of green space for psychosis. Considering the multidimensionality of the self, it is proposed that urban green space design aimed at improving mental health ideally impacts the complexity of self-facets and thus restores the individual’s self.

Newly developed Bayesian perspectives on schizophrenia hold out the promise that a common underlying mechanism can account for many, if not all, of the positive symptoms of schizophrenia. If this is the case, then understanding how schizophrenic minds go awry could shine light on how healthy minds maintain a sense of self. This article investigates this Bayesian promise by examining whether the approach can indeed account for the difficulties with self-awareness experienced in schizophrenia. While I conclude that it cannot, I (...) nonetheless maintain that understanding how the self breaks down in schizophrenia tells us much about how and why the self functions in normal human circumstances. I proceed first by recounting in some detail a Bayesian interpretation of perception, schizophrenia, and self-awareness, as well as some of the empirical data supporting this interpretation, then by exploring aspects of schizophrenia that this approach leaves out. I conclude by discussing what the “left out” aspects tell us about self-awareness, thereby convincing the reader that studying patients with schizophrenia is indeed a useful avenue for understanding awareness of self.

We investigated output-monitoring errors over speech based on findings in the research on the sense of agency. Several words were presented one-by-one, and we asked participants to say the word aloud, mouth the word, or imagine saying the word aloud. Later, participants were asked whether each word was said aloud. We found that the “said aloud” response was higher for generated words than that for observed words; it was decreased when the pitch of the feedback was lowered but still higher (...) than when no feedback was received, and it was the same when no feedback was received and when feedback was replaced by another’s voice. Furthermore, we found that the “said aloud” response did not decrease even when the altered feedback was received with a short delay. These results were discussed according to the sense of agency and agency memory. (shrink)

My response to the preceding essays begins with some preliminaries about my terminology, approach, and conception of rationality as a regulative ideal. I then comment on the Murphy's discussion about normal religious belief and religious delusions, and on causal assumptions challenged by Langdon's folies à deux. Responding to Gerrans's imagination-based account of delusion and Hohwy's discussion of illusions, I next try to envision what both doxastic and imagination-based approaches might have overlooked by asking whether there can be delusional feelings. Final (...) comments address the place of phenomenology within Coltheart's two-factor theorizing. (shrink)

Based on Pacherie’s dynamic theory of intentions, this study investigated how the way an intention is formed and sustained affects action performance and the experience of control during acting. In Experiment 1, task-irrelevant verbal commands were given while participants responded to stimuli in a two-choice reaction time task. The commands referred to an action goal congruent or incongruent with the actor’s current intention, or ordered the initiation or abortion of the action. In Experiment 2, the same commands were given as (...) participants freely chose between two actions. The distractors affected performance in the reactive task only. In both experiments, feelings of control were based on movement parameters as well as perceived matches between distractors and intended actions. These findings suggest that the way an intention is implemented affects how well it can be shielded against external perturbations and how much one feels in control. (shrink)

Consider a potter throwing a vessel on the wheel. Think of the complex ways brain, body, wheel and clay relate and interact with one another throughout the different stages of this activity and try to imagine some of the resources (physical, mental or biological) needed for the enaction of this creative process. Focus, for instance, on the first minutes of action when the potter attempts to centre the lump of clay on the wheel. The hands are grasping the clay. The (...) fingers, bent slightly following the surface curvature, sense the clay and exchange vital tactile information necessary for a number of crucial decisions that are about to follow in the next few seconds. What is it that guides the dextrous positioning of the potter’s hands and decides upon the precise amount of forward or downward pressure necessary for centring a lump of clay on the wheel? How do the potter’s fingers come to know the precise force of the appropriate grip? What makes these questions even more fascinating is the ease by which the phenomena which they describe are accomplished. Yet underlying the effortless manner in which the potter’s hand reaches for and gradually shapes the wet clay lies a whole set of conceptual challenges to some of our most deeply entrenched assumptions about what it means to be a human agent.

There is converging evidence from developmental and cognitive psychology, as well as from neuroscience, to suggest that the self is both special and social, and that self-other interaction is the driving force behind self-development. We review experimental findings which demonstrate that human infants are motivated for social interactions and suggest that the development of an awareness of other minds is rooted in the implicit notion that others are like the self. We then marshal evidence from functional neuroimaging explorations of the (...) neurophysiological substrate of shared representations between the self and others, using various ecological paradigms such as mentally representing one's own actions versus others' actions, watching the actions executed by others, imitating the others' actions versus being imitated by others. We suggest that within this shared neural network the inferior parietal cortex and the prefrontal cortex in the right hemisphere play a special role in the essential ability to distinguish the self from others, and in the way the self represents the other. Interestingly, the right hemisphere develops its functions earlier than the left. (shrink)

The paper seeks to argue that the feeling of being part of a larger whole, considered to be a major feature of spiritual experience in some traditions, amounts to a change in the way the self is pre-reflectively understood. Further, the paper argues that some recent developments in the study of cognition support the case for such a revision in self-conception, and this can be used to build up a secular understanding of spirituality. The paper proceeds by making use of (...) Abraham Maslow's account of peak experience along with some accounts of both ancient and contemporary forms of spirituality to argue that the feeling of being part of a larger whole amounts to a significant shift from the separative self-conception implicit in everyday behavior. Subsequently, it is argued that some extant theories on cognition point at the illusory nature of separative self-conception. (shrink)

Abstract: The notion of a self-pattern, as developed in the pattern theory of self, which holds that the self is best explained in terms of the kind of reality that pertains to a dynamical pattern, acknowledges the importance of neural dynamics, but also expands the account of self to extra-neural (embodied and enactive) dynamics. The pattern theory of self, however, has been criticized for failing to explicate the dynamical relations among elements of the self-pattern; as such, it seems to be (...) nothing more than a mere list of elements. We’ll argue that the dynamics of a self-pattern are reflected in three significant and interrelated ways that allow for investigation. First, a self-pattern is reflectively reiterated in its narrative component. Second, studies of psychiatric or neurological disorders can help us understand the precise nature of the dynamical relations in a self-pattern, and how they can fail. Third, referencing predictive processing accounts, neuroscience can also help to explicate the dynamical relations that constitute the self-pattern. (shrink)

Human self-consciousness operates at different levels of complexity and at least comprises five different levels of representational processes. These five levels are nonconceptual representation, conceptual representation, sentential representation, meta-representation, and iterative meta-representation. These different levels of representation can be operationalized by taking a first-person-perspective that is involved in representational processes on different levels of complexity. We refer to experiments that operationalize a first-person-perspective on the level of conceptual and meta-representational self-consciousness. Interestingly, these experiments show converging evidence for a recruitment of (...) medial cortical and parietal regions during taking a first-person-perspective, even when operating on different degrees of complexity. These data lend support for the speculative hypothesis, that there exist a neural signature for human self-consciousness that is recruited independent from the degree of representational complexity to be performed.
