The study of the feeling of knowing may have implications for some of the metatheoretical issues concerning consciousness and control. Assuming a distinction between information-based and experience-based metacognitive judgments, it is argued that the sheer phenomenological experience of knowing (''noetic feeling'') occupies a unique role in mediating between implicit-automatic processes, on the one hand, and explicit-controlled processes, on the other. Rather than reflecting direct access to memory traces, noetic feelings are based on inferential heuristics that operate (...) implicitly and unintentionally. Once such heuristics give rise to a conscious feeling that feeling can then affect controlled action. Examination of the cues that affect noetic feelings suggest that not only do these feelings inform controlled action, but they are also informed by feedback from the outcome of that action. (shrink)

In Feeling of Knowing cases, subjects have a form of consciousness about the presence of a content (such as an item of information) without having access to it. If this phenomenon can be correctly interpreted as having to do with consciousness, then there would be a P-conscious mental experience which is dissociated from access.

Feelings of knowing (FoK) are introspective self-report ratings of the felt likelihood that one will be able to recognize a currently unrecallable memory target. Previous studies have shown that FoKs are influenced by retrieved fragment knowledge related to the target, which is compatible with the accessibility hypothesis that FoK is partly based on currently activated partial knowledge about the memory target. However, previous results have been inconsistent as to whether or not FoKs are influenced by the accuracy of such (...) information. In our study (N = 26), we used a recall-judge-recognize procedure where stimuli were general knowledge questions. The measure of partial knowledge was wider than those applied previously, and FoK was measured before rather than after partial knowledge. The accuracy of reported partial knowledge was positively related to subsequent recognition accuracy, and FoK only predicted recognition on trials where there was correct partial knowledge. Importantly, FoK was positively related to the amount of correct partial knowledge, but did not show a similar incremental relation with incorrect knowledge. (shrink)

Rightness, not familiarity, is the feeling of knowing. Rightness and familiarity are distinct at both the functional and phenomenological levels of analysis. In problem solving, for example, an unfamiliar solution can still feel right. Rightness is the fringe experience permeating all cases of felt meaning in consciousness, and can occur even when the retrieval of specific content is for whatever reason blocked (e.g., in a tip of the tongue experience). For the most extensive published treatment of rightness and (...) fringe experience, see Mangan (2003): "The conscious 'fringe': Bringing William James up to date" in Essential Sources in the Scientific Study of Consciousness, MIT press.

The present study investigated how knowledge-gaps, measured by feeling-of-knowing, and individual differences in epistemic curiosity contribute to the arousal of state curiosity and exploratory behaviour for 265 (210 women, 55 men) university students. Participants read 12 general knowledge questions, reported the answer was either known (“I Know”), on the tip-of-the-tongue (“TOT”), or unknown (“Don't Know”), and indicated how curious they were to see each answer, after which they could view any answers they wanted. Participants also responded to the (...) Epistemic Curiosity (EC) and Curiosity as a Feeling-of-Deprivation (CFD) scales. “TOT” was associated with the smallest knowledge-gap, most curiosity and exploration, and feelings of uncertainty and tension as measured by the CFD scale. “Don't Know” corresponded with the largest knowledge-gap, less curiosity and exploration, and positive feelings of interest as measured by the EC scale. “I Know” states, which reflected the absence of a knowledge-gap, involved the least curiosity and exploration.

In Koriat's paper ''The Feeling of Knowing: Some Metatheoretical Implications for Consciousness and Control,'' he asserts that the feeling of knowing straddles the implicit and explicit, and that these conscious feelings enter into a conscious control process that is necessary for controlled behavior. This assertion allows him to make many speculations on the nature of consciousness itself. We agree that feelings of knowing are produced through a monitoring of one's knowledge, and that this monitoring can (...) affect the control of behavior such as whether or not to search memory for an answer. Further, we believe that monitoring of performance with a strategy can also affect cognition control and strategy selection; however, we also believe that frequently this monitoring and control occurs without conscious awareness. Feeling of knowing has received an inordinate amount of attention because it lies behind the highly recognizable tip-of-the-tongue phenomenon that represents one of the rare cases of conscious monitoring. There are other feelings of knowing which are much more common and are not accompanied by conscious awareness. These are evident in the early selection of a strategy for answering a problem. In our view, the research on feeling of knowing will not resolve the question of whether consciousness is merely epiphenomenal. (shrink)

In a masked priming experimental paradigm, we studied a possible subliminal perception effect on a semantic selection task. To gauge the degree to which subjects solved the SST consciously, they subsequently reported their level of confidence of having made a correct response. This was done on each trial, and the subjects used individually constructed category rating scales to do so, in order to achieve a more sensitive measurement of which trials were influenced by conscious processes. During the construction of these (...) individual rating scales, subjects verbally reported their experiences after each trial. The present study failed to find evidence of performance above chance level when subjects themselves reported to be at chance level. In fact, performance closely covaried with subjects' confidence ratings. About half of the subjects reported they would sometimes experience a 'feeling of knowing' the correct response to the SST, despite being unaware of the specific identity of the prime. From this, we observe the methodological point that in order to demonstrate subliminal perception in a masked priming paradigm with a semantic selection task it is not enough to demonstrate a lack of conscious visual perception of the prime, since a vague, yet conscious, FOK experience can be used by subjects to solve the task.

The ability to reflect on and monitor memory processes is one of the most investigated metamemory functions, and one of the important ways consciousnesses interacts with memory. The feeling-of-knowing is one task used to evaluate individual’s capacity to monitor their memory. We examined this reflective function of metacognition in older adults. We explored the contribution of metacognition to episodic memory impairment, in relation to the idea that older adults show a reduction in memory awareness characteristic of episodic memory. (...) A first experiment showed that age affects the accuracy of FOK when predictions are made on an episodic memory task but not on a semantic memory task, suggesting a particular role for episodic memory awareness in metacognitive evaluations. A second experiment showed that the age-difference in episodic FOK accuracy was removed if one took into account subjective reports of memory awareness, or recollection. We argue that the FOK deficit specific to episodic memory is based on a lack of memory awareness manifest as a recollection deficit. (shrink)

Research has demonstrated that feeling-of-knowing judgments are affected by the amount of accessible information related to an inaccessible target. Further, studies have demonstrated that, in some situations, FOK judgment magnitude is not only related to the amount of accessed features, but also the correctness of those features . The present study examined the conditions under which the correctness of features would influence FOK judgment magnitude. We hypothesized that accuracy of retrieved features would influence FOK judgments, but only in (...) situations where semantically meaningful information was accessible. In three experiments, we manipulated accessibility of semantic information. In all experiments, the quantity, or amount of retrieved partial information had a greater impact on FOK judgments than the accuracy of that information. However, in situations where semantic information was accessible, accuracy of retrieved semantic features also influenced FOK judgment magnitude, and later recognition. (shrink)

This research investigated the effect of divided attention at encoding on feeling-of-knowing . Participants had to learn a 60 word-pair list under two experimental conditions, one with full attention and one with divided attention . After that, they were administered episodic FOK tasks with a cued-recall phase, a FOK phase and a recognition phase. Our results showed that DA at encoding altered not only memory performance, but also FOK judgments and FOK accuracy. These findings throw some light on (...) the central role of the quality of memory encoding to make accurate FOK judgments and provide new evidence supporting the relationship between memory and metamemory judgments.

The theoretical approach described in a series of articles (Jarvilehto, 1998a,b,c, 1999, 2000) is developed further in relation to the problems of emotion, consciousness, and brain activity. The approach starts with the claim that many conceptual confusions in psychology are due to the postulate that the organism and the environment are two interacting systems (”Two systems theory”). The gist of the approach is the idea that the organism and environment form a unitary system which is the basis of subjective experience. (...) This starting point leads to the conception of emotions as reorganization of the organism-environment system, and entails that emotion and knowledge are only different aspects of the same process. In the first part of the article the general outline of the approach is sketched, and in a subsequent second part (Jarvilehto, 2001) the relations between emotions, consciousness, and brain activity will be discussed in detail.

A. Koriat distinguishes between feeling-based and inferentially based feeling-of-knowing judgments. The former are attributable to partial information that is activated in implicit memory but not fully articulated. They are not, however, attributable to direct access to the target-an hypothesis that Koriat specifically repudiates. While there is considerable merit in the distinction that Koriat draws, and his emphasis on the possibility that people base at least some of their metacognitive judgments on implicit information seems well founded, it is (...) argued that his rejection of the direct access view is premature. There may be a state-a true noetic state-in which people actually know the answer before they are able to express it. A case is made for further consideration of the scientific merits of the direct-access view of the noetic feelings people experience in imminent tip-of-the-tongue (TOT) states. (shrink)

In the latter part of this two-article sequence, the concept of emotion as reorganization of the organism-environment system is developed further in relation to consciousness, subjective experience and brain activity. It is argued that conscious emotions have their origin in reorganizational changes in primitive co-operative organizations, in which they get a more local character with the advent of personal consciousness and individuality, being expressed in conscious emotions. However, the conscious emotion is not confined to the individual only, but it gets (...) its content and the emotional quale in the social context, and in relation to the norms of the given culture. Emotion is fundamentally the process of ascription of meaning to the parts of the world which are relevant in the achievement of results of behavior. Although emotions may be studied as reorganizational processes in the organism-environment system with the help of physiological recordings and behavioral observations, it is argued — in contrast to the mainstream cognitive science — that emotions cannot be localized in the brain, although the brain is important in their generation as a part of the organism-environment system. It is suggested that the parts of the brain most closely related to emotional expression contain neurons subserving functional systems which are formed in early development, and which are therefore most intimately related to reorganizational processes in the organism-environment system.

The results of three experiments suggest that pre-existing mood increases the intensity of affectively congruent emotions while dampening the intensity of incongruent emotions independent of attributional knowledge. This result was obtained using a new method for inducing mood states unobtrusively and with minimal or no cognitive concomitants. The results of Experiment 1 revealed that for participants who were exposed to positive feedback a pre-existing positive mood led to stronger feelings of pride in comparison to negative mood. The results of Experiments (...) 2 and 3 suggest that pre-existing mood directly influences the experience of subsequently elicited emotions independent of what one knows about the causes of this feeling. When participants were required to differentiate between the funniness of a cartoon and their subjective humour response, mood influenced only the latter judgement (Experiment 2). In Experiment 3, reminding participants of the mood induction resulted in a contrast effect in judging the funniness of a cartoon. However, the pre-existing mood continued to exert an assimilation effect on the overt mirth response. In conclusion, these results suggest that the feeling and knowledge component are partly independent bases of emotional responses. (shrink)

Authenticity is often defined as the extent to which people feel that they know and express their true selves. Research in the psychological sciences suggests that people view true selves as more morally good than bad and that this “virtuous” true self may be a central component of authenticity. In fact, there may be reasons to suspect that authenticity serves as a cue that one’s behaviors are virtuous, and feelings of authenticity may help sustain virtuous actions. However, in previous research, (...) operationalizations of virtue may not clearly capture virtue as virtue theorists might recognize it. The possibility that feelings of authenticity keep people oriented toward virtuous activities is compatible with theorizing, but the precise ways that it might do so has not received direct conceptual or empirical scrutiny. We propose an interdisciplinary hypothesis of how feelings of authenticity could function to serve as a feedback mechanism for virtuous behavior. Feelings of authenticity could play a role in sustaining motivation to engage in virtuous activity insofar as the experience of subjective authenticity encourages one to approach that activity or environment in the future. Furthermore, virtuous behavior incorporates a few key elements that are predictive of experiencing subjective authenticity. We review emerging research that offers initial support for the idea that authenticity may guide sustained and virtuous civic action and develop a theoretical framework that positions authenticity as integral to sustained virtuous behavior.

Information is more likely believed to be true when it feels easy rather than difficult to process. An ecological learning explanation for this fluency-truth effect implicitly or explicitly presumes that truth and fluency are positively associated. Specifically, true information may be easier to process than false information and individuals may reverse this link in their truth judgments. The current research investigates the important but so far untested precondition of the learning explanation for the fluency-truth effect. In particular, five experiments (total (...) N = 712) test whether participants experience information known to be true as easier to process than information known to be false. Participants in Experiment 1a judged true statements easier to read than false statements. Experiment 1b was a preregistered direct replication with a large sample and again found increased legibility for true statements—importantly, however, this was not the case for statements for which the truth status was unknown. Experiment 1b thereby shows that it is not the actual truth or falsehood of information but the believed truth or falsehood that is associated with processing fluency. In Experiment 2, true calculations were rated as easier to read than false calculations. Participants in Experiment 3 judged it easier to listen to calculations generally known to be true than to calculations generally known to be false. Experiment 4 shows an effect of truth on processing fluency independent of statement familiarity. Discussion centers on the current explanation for the fluency-truth effect and the validity of processing fluency as a cue in truth judgments. (shrink)

The notion of community infers unity and a source of moral obligations in an organisational ethic between individuals or groups. As such, a community, having a strong sense of collective identity, may foster collective action to promote social change for the betterment of society. This research critically explores notions of community through analysing discursive identity construction practices within a member-owned urban consumer co-operative public house in the UK. A strong sense of community is an often-claimed CC characteristic. The paper’s main (...) contributions stem from using the lens of identity work to critically unpack the notion of community through highlighting paradoxical tensions of community residing within CCs. The findings reveal that the notion of community may be illusionary with counter-veiling forces, one that reflects a more traditional sense of connection, attachment and communion, and the other of boundaries, disconnection or division. As these repertoires collide, tensions are evident between the hegemonic discourse of neoliberal managerialism and that of democratic collective ownership. Despite these individual-level tensions, communities may operate within boundaries enabling an organisational and societal ethic, beyond the individual. (shrink)

Individuals differ considerably in their emotion experience. Some experience emotions in a highly differentiated manner, clearly distinguishing among a variety of negative and positive discrete emotions. Others experience emotions in a relatively undifferentiated manner, treating a range of like-valence terms as interchangeable. Drawing on self-regulation theory, we hypothesised that individuals with highly differentiated emotion experience should be better able to regulate emotions than individuals with poorly differentiated emotion experience. In particular, we hypothesised that emotion differentiation and emotion regulation would be (...) positively related in the context of intense negative emotions, where the press for emotion regulation is generally greatest. To test this hypothesis, participants' negative and positive emotion differentiation was assessed using a 14-day diary protocol. Participants' regulation of negative and positive emotions was assessed using laboratory measures. As predicted, negative emotion differentiation was positively related to the frequency of negative emotion regulation, particularly at higher levels of emotional intensity. (shrink)

David Chalmers appears to assume that we can meaningfully discuss what goes on in human heads without paying any attention to the words in which we couch our statements. This paper challenges this assumption and argues that the initial problem is that of metalanguage: if we want to say something clear and valid about us humans, we must think about ourselves outside conceptual English created by one particular history and culture and try to think from a global, panhuman point of (...) view. This means that instead of relying on untranslatable English words such as 'consciousness' and 'experience' we must try to rely on panhuman concepts expressed in cross-translatable words such as THINK, KNOW, and FEEL (Wierzbicka, 2018). The paper argues that after 'a hundred years of consciousness studies' it is time to try to say something about us (humans), about how we think and how we differ from cats and bats, in words that are clear, stable, and human rather than parochially English.

From one of the world's leading neuroscientists--a succinct, illuminating, wholly engaging investigation of the phenomenon of consciousness. In recent decades, many philosophers and cognitive scientists have declared the question of consciousness unsolvable, but Antonio Damasio is convinced that recent findings in neurobiology, psychology, and AI have given us the necessary tools to solve its mystery. Now, he not only elucidates its myriad aspects, but presents his analysis and insights in a way that is faithful to our own intuitive sense of (...) the experience of consciousness. In the 45 brief chapters of the book, he helps us understand the relation between consciousness and mind; why being conscious is not the same as either being awake or sensing; the essential role of feeling; and the biological brain and development of consciousness. He synthesizes the recent findings of various sciences with the outlook of philosophy, and, most significantly, presents his original research which has transformed our understanding of the brain and human behavior. Here is an indispensable guide to understanding consciousness, the fundamental human capacity for informing--and transforming--our experience of the world around us and our perception of our place in it.

The main goals of this paper are two. First, it articulates what kinds of knowing pure knowing is in its narrow sense pure knowing as the capacity of moral judgment; pure knowing as moral knowledge and standard. Besides, it analyses pure knowing’s different features through a phenomenological description. All these aspects of pure knowing are tied by moral feeling. Second, this paper addresses two sets of theoretical problems that have been raised in Confucian (...) discourse with respect to pure knowing and Heavenly principle, primarily those that render Wang’s notion of pure knowing to be static recognition toward particular moral issues, or immediate response, which reading cannot really admit the possibilities of extension, reflection, moral cultivation, and reform of institution; and those that understand pure knowing to be merely abstract without concrete content, such as merely being a metaphysical substance. When properly understood, that is, from the perspective of moral emotions, Wang Yangming’s account of pure knowing provides for the possibilities of enhancement and cultivation, while insisting that the content of pure knowing is always accessible to us.

Abstract.Differences in methods of knowing correlate with differences in concepts about what is known. This is an underlying issue in science and religion. It is seen, first, in Arthur Peacocke's reasoning about God as transcendent and personal, is based on an assumption of correlative thinking that like causes like. This contrasts with a notion of causation in empirical science, which explains the emergence of new phenomena as originating from temporally prior phenomena quite unlike that which emerges. The scientific understanding (...) of causation is compatible with a naturalistic theism that holds a nonpersonal model of God as the creative process. However, focusing on the immanence of God, there is a second correlation between methods of knowing and concepts of God. Classical empiricism, used by science, correlates with God understood nonpersonally as the creative process. Radical empiricism, in which feelings and not only sense perceptions have cognitive import, opens up the possibility that one can experience Peacocke's personal, panentheistic God as pattern‐forming influence. I illustrate this second method‐concept correlation with a personal experience. (shrink)

By “pantheism” I mean to pick out a model of God on which God is identical with the totality of existents constitutive of the universe. I assume that, on pantheism, God is an omnispatiotemporal mind who is identical with the universe. I assume that, given divine omnispatiotemporality, God knows everything that can be known in the universe. This includes having knowledge de se of the minds of every conscious creature. Hence, if God has knowledge de se of the minds of (...) every conscious creature, then divine omniscience implies omnisubjectivity. Assuming that eternalism is true, robust temporal passage is an illusion. But, conscious creatures, such as human persons, experience robust temporal passage. If God has the attribute of omnisubjectivity, then God experiences temporal passage. However, God also has a unified experience of the entire spatiotemporal continuum. God’s having these two perspectives creates a tension for pantheism given that God would seem to experience both temporal passage and an absence of temporal passage. I compare non-personal pantheism and personal pantheism and consider which one has better resources to answer the foregoing puzzle. I argue that personal pantheism is better equipped to address this problem than non-personal pantheism. (shrink)

The emotions play a crucial role in our apprehension of meaning, value, or significance — and their felt quality is intimately related to the sort of awareness they provide. This is exemplified most clearly by cases in which dispassionate cognition is cognitively insufficient, because we need to be emotionally agitated in order to grasp that something is true. In this type of affective experience, it is through a feeling of being moved that we recognize or apprehend that something is (...) the case. And that is why our emotions are epistemically indispensable: namely, because they give us access to significant truths. In this essay, I explain how the phenomenally felt character of an emotion is intimately linked with its intentionality. Intellectual activity divorced from affective feeling is profoundly lacking — not only in its qualitative feel, but also in its epistemic import, or its ability to inform us about matters of significance. A better appreciation of how the living body is involved in affective experience should help us to understand the distinctive kind of embodied cognition that emotional responses involve. It also ought to resolve confusions about phobic responses and other “recalcitrant” emotions, which are not divorced from cognition as many have claimed. (shrink)

I tend to think of myself as bodily. Probably, so do you. Philosophically this takes some explaining. A candidate explanation is this: The bodily self is a physical agent. Knowledge of oneself as bodily is fundamentally knowledge of oneself as agentive; such knowledge is grounded in both experience of oneself as instantiating a bodily structure that affords a limited range of actions; and experience of oneself as a physical agent that tries to perform a limited range of actions over time. (...) By contrast René Descartes famously argued that all self-knowledge is grounded in, and cannot extend beyond, knowledge of oneself as a mental entity. If correct this would preclude the possibility of any knowledge of a bodily self, for such a thing would ex hypothesi not exist. Accordingly, this dissertation serves a dual purpose: to demonstrate why a Cartesian theory of self-knowledge is no threat to an account of bodily self knowledge; and to provide such an account. This dual purpose is achieved over the course of three chapters. The first chapter will set up the remaining two, by introducing the notion of self-identifying judgements, providing an argument in favour of bodily self knowledge on its basis, and noting two failures of this argument in light of a Cartesian response. The second and third chapter are respective attempts to address these two failures. The second chapter is explicitly concerned with the Cartesian, but is overall devoted to giving an account of the relationship between bodily experience and action. The third chapter is more programmatic, comprising a consistent set of suggestions concerning the sense of agency and its role in an account of bodily self knowledge. (shrink)

Consciousness ties together knowledge and feeling, or sapience and sentience. The connection between these two constitutive aspects — the informational and the phenomenal — is deep, but how are we to make sense of it? One influential approach maintains that sentience ultimately reduces to sapience, namely, that phenomenal consciousness is a function of representational relations between mental states which, barring these relations, would not, and could not, be conscious. In this paper I take issue with this line of thought, (...) arguing that neither of these salient aspects of consciousness reduces to the other. Instead, I offer an explanatory framework which takes both sentience and sapience as ontological fundamentals and explore how they co-evolve. In particular, I argue that while epistemic access cannot generate experience from scratch it does play a crucial role in constituting an important form of higher-order experience, namely, the capacity to experience a sense of ownership over one’s experiential domain.

In this article, we aim to evaluate the role of robots’ personality-driven behavioural patterns on users’ intention to use in an entertainment scenario. Toward such a goal, we designed two personalities: one introverted with an empathic and self-comparative interaction style, and the other extroverted with a provocative and other-comparative interaction style. To evaluate the proposed technology acceptance model, we conducted an experiment (N = 209) at a public venue where users were requested to play a game with the support of (...) the TIAGo robot. Our findings show that the robot personality affects the acceptance model and three relevant drivers: perceived enjoyment, perceived usefulness, and social influence. The extroverted robot was perceived as more useful than the introverted, and participants who interacted with it were faster at solving the game. On the other hand, the introverted robot was perceived as more enjoyable but less useful than the extroverted, and participants who interacted with it made fewer mistakes. Taken together, these findings support the importance of designing proper robot personalities in influencing users’ acceptance, featuring that a given style can elicit a different driver of acceptance.

Episodic memory involves the sense that it is “first-hand”, i.e., originates directly from one’s own past experience. An account of this phenomenological dimension is offered in terms of an affective experience or feeling specific to episodic memory. On the basis of recent empirical research in the domain of metamemory, it is claimed that a recollective experience involves two separate mental components: a first-order memory about the past along with a metacognitive, episodic feeling of knowing. The proposed two-tiered (...) account is contrasted with other, reductionist two-tiered accounts as well as with reflexive accounts of episodic memory to be found in the literature. (shrink)

Human subjects seem to have a type of introspective access to their mental states that allows them to immediately judge the types and intensities of their occurrent emotions, as well as what those emotions are about or “directed at”. Such judgments manifest what I call “emotion-direction beliefs”, which, if reliably produced, may constitute emotion-direction knowledge. Many psychologists have argued that the “directed emotions” such beliefs represent have a componential structure, one that includes feelings of emotional responses and related but independent (...) representations of what those feelings are about. I argue that such componentiality may help to explain how emotion-direction knowledge is achievable. I begin by developing a hybrid view of introspection that combines David Chalmers’ phenomenal realism with Alvin Goldman’s “partial redeployment” account of meta-belief content. I then provide a process-reliabilist account of introspectively gained emotion-direction knowledge that outlines the minimum conditions of reliably forming emotion-direction beliefs, and specifies several ways in which the warrant of such beliefs could be defeated by relevant counterfactual alternatives. The overall account suggests how distinct introspective processes might be epistemically synergistic. (shrink)

For hundreds of millions of years before the recent emergence of reason, evolution elaborated a multiplicity of ways of knowing through feelings, which remain valid today. Each way of knowing, including reason, is mediated by a ‘mental organ’ which is a population of neurons bearing a particular neurotransmitter receptor (e.g. serotonin-7, histamine-1, alpha-2C). Each mental organ adds spice to our lives. Reason coevolved with a pre-existing affective domain, and is designed to be informed by affective input. When reason (...) reigns at the cost of losing touch with the other ways of knowing, we retain the ability to manipulate nature, but we do not understand its essence and cannot make wise judgements.
