Sublinhando que a evocação dos acontecimentos que tiveram lugar ab origine convergir, segundo a perspectiva mítico-religiosa, para a manifestação das sagradas, de acordo com o referencial teórico-conceitual de Eliade, o artigo assinala que tal invocação implica uma correlação de narrativas míticas e gestos e ações paradigmáticas que se destinam a suscitar o poder sagrado e a produção de seus efeitos, ressaltando a prece como poder mágico de exercer influência sobrenatural, como afirma Mauss. Dessa forma, analisando a oração que ressalta o (...) monoteísmo judaico-cristão, o artigo assinala o relacionamento pactual que encerra Javé e Israel como um processo que implica a Sua invocação como Deus, que converge para manifestações e operações na vida do povo em sua realidade concreta , perfazendo, segundo a perspectiva bíblico-teológica neotestamentária, uma construção que encerra a expressão da existência escatológica e realização de si em Bultmann. Finalizando, baseado na perspectiva teológico-filosófica de Tillich, o texto rápido o poder que implica a oração em um processo que se sobrepõe às estruturas supraindividuais de destruição através do novo ser que Deus-Homem Jesus Cristo manifesta e que envolve uma capacidade de superar as estruturas escravizadoras do mal e as consequências autodestruidoras do estado de alienação existencial.

Recent work by Kahan et al. (2017) on the psychology of motivated numeracy in the context of intracultural disagreement suggests that people are less likely to employ their capabilities when the evidence runs contrary to their political ideology. This research has so far been carried out primarily in the USA regarding the liberal–conservative divide over gun control regulation. In this paper, we present the results of a modified replication that included an active reasoning intervention with Western European participants regarding both (...) the hierarchy–egalitarianism and individualism–collectivism divides over immigration policy (n = 746; considerably less than the preregistration sample size). We reproduce the motivated numeracy effect, though we do not find evidence of increased polarization of high-numeracy participants. (shrink)

The purpose of this paper is to provide a detailed technical protocol analysis of chess masters' evaluative expertise, paying particular attention to the analysis of the structure of their memory process in evaluating foreseen possibilities in games of dynamic equilibrium. The paper has two purposes. First, to publish a results chapter from my DPhil thesis (in revised journal article form) attending to the measurement of foresight in chess masters' evaluation process, testing alternative theories of cognitive expertise in the domain of (...) chess; and second to provide a subset of the technical graphical analysis that corresponds to that measurement to preserve this protocol analysis for access in the academic domain for future studies of expert memory and foresight (e.g., Ericsson & Simon, 1993). The step-by-step protocol analysis consists of: (i) an introduction to foresight cognition as hypothesis testing, (ii) a theoretical review in the domain of chess masters' expertise according to the theoretical frameworks in that field purporting hypotheses relevant to chess masters' evaluative skill processes, and (iii) summary tables and non-parametric statistical analysis corroborating chunking theory frameworks of expert cognition (e.g., DeGroot, 1965; Newell & Simon, 1972; Gobet, 1998; Gobet et al., 2004), and refuting the alternative search-evaluation models (e.g., Holding & Reynolds, 1982). Moreover, the journal article espouses the preservation of the traditional protocol analysis method core to the field of expert cognition (DeGroot, 1969; Kotov, 1971). The full protocol analysis can be found in monograph form here on my SSRN profile in ‘The role of falsification in hypothesis testing’. It takes the form of a specialist population study (e.g., detailed case study work; Luria, 1987). Thus the outline consists of a short introduction, a theoretical methodological review discussing protocol analysis methods for specialist population studies in cognition (with particular attention to the preservation of protocol analysis methods for chess studies in cognition and expert memory/ with a fresh angle on the foresight process), and the full set of protocol analyses with corresponding problem behaviour graphs. A subset of the main results has been published elsewhere (e.g., Cowley & Byrne, 2004; Cowley 2006), receiving scientific and scientific journalistic acclaim (e.g., Nature Online News 2004).

This paper considers the practical question of why people do not behave in the way they ought to behave. This question is a practical one, reaching both into the normative and descriptive domains of morality. That is, it concerns moral norms as well as empirical facts. We argue that two main problems usually keep us form acting and judging in a morally decent way: firstly, we make mistakes in moral reasoning. Secondly, even when we know how to act and judge, (...) we still fail to meet the requirements due to personal weaknesses. This discussion naturally leads us to another question: can we narrow the gap between what people are morally required to do and what they actually do? We discuss findings from neuroscience, economics, and psychology, considering how we might bring our moral behavior better in line with moral theory. Potentially fruitful means include nudging, training, pharmacological enhancement, and brain stimulation. We conclude by raising the question of whether such methods could and should be implemented.

Change blindness is a phenomenon of visual perception that occurs when a stimulus undergoes a change without this being noticed by its observer. Since it was first described in the 1990s, change blindness has provided a unique means to investigate the role of attention in visual processing. To date, the effect has been produced by changing images displayed on screen as well as changing people and objects in an individual’s environment. In this study, we combine these two approaches to directly (...) compare the levels of change blindness produced in real-world and on-screen scenarios. We use a single series of museum artefacts and two groups of participants to simultaneously produce saccade-contingent change blindness in a real-world scenario, and camera pan-contingent change blindness in an on-screen scenario. We present the results in two parts. First, we find no significant difference between the mean levels of change blindness produced in on-screen and real-world scenarios by the same visual stimuli. Second, we identify a group of artefacts that were associated with a high level of change blindness in both scenarios and a group that were associated with a low level of change blindness in both scenarios. We suggest that the difference in change blindness levels results from bottom-up influences including the visible area and contrast of changes. We discuss the relation of these findings to our understanding of change detection as a part of visual processing, as well as the insights they offer to our understanding of the experience of viewing objects within a museum setting.

There are two competing theoretical frameworks with which cognitive sciences examines how people reason. These frameworks are broadly categorized into logic and probability. This paper reports two applied experiments to test which framework explains better how people reason about evidence in criminal cases. Logical frameworks predict that people derive conclusions from the presented evidence to endorse an absolute value of certainty such as ‘guilty’ or ‘not guilty’ (e.g., Johnson-Laird, 1999). But probabilistic frameworks predict that people derive conclusions from the presented (...) evidence in order that they may use knowledge of prior instances to endorse a conclusion of guilt which varies in certainty (e.g., Tenenbaum, Griffiths, & Kemp, 2006). Experiment 1 showed that reasoning about evidence of prior instances, such as disclosed prior convictions, affected participants’ underlying ratings of guilt. Participants’ guilt ratings increased in certainty according to the number of disclosed prior convictions. Experiment 2 showed that participants’ reasoning about evidence of prior convictions and some forensic evidence tended to lead participants to endorse biased ‘guilty’ verdicts when rationally the evidence does not prove guilt. Both results are predicted by probabilistic frameworks. The paper considers the implications for logical and probabilistic frameworks for reasoning in the real world. (shrink)

Can people consistently attempt to falsify, that is, search for refuting evidence, when testing the truth of hypotheses? Experimental evidence indicates that people tend to search for confirming evidence. We report two novel experiments that show that people can consistently falsify when it is the only helpful strategy. Experiment 1 showed that participants readily falsified somebody else’s hypothesis. Their task was to test a hypothesis belonging to an ‘imaginary participant’ and they knew it was a low quality hypothesis. Experiment 2 (...) showed that participants were able to falsify a low quality hypothesis belonging to an imaginary participant more readily than their own low quality hypothesis. The results have important implications for theories of hypothesis testing and human rationality. (shrink)

Many theories in philosophy, law, and psychology, make no distinction in meaning between causing and enabling conditions. Yet, psychologically people readily make such distinctions each day. In this paper we report three experiments, showing that individuals distinguish between causes and enabling conditions in brief descriptions of wrongful outcomes. Respondents rate actions that bring about outcomes as causes, and actions that make possible the causal relation as enablers. Likewise, causers (as opposed to enablers) are rated as more responsible for the outcome, (...) as liable to longer prison sentences, and as liable to pay higher fines. Moreover, the more actors involved, the more blame volume there is psychologically to be apportioned between them. The implication is that theories and the law in practice, both criminal and civil, may dangerously mismatch the intuitions of those to whom they are supposed to apply. The findings are discussed in light of contemporary psychological theories of how people reason about cause. -/- The paper presents the extended findings supplementary to the conference paper: Frosch, C.

DNA evidence is one of the most significant modern advances in the search for truth since the cross examination, but its format as a random-match-probability makes it difficult for people to assign an appropriate probative value (Koehler, 2001). While Frequentist theories propose that the presentation of the match as a frequency rather than a probability facilitates more accurate assessment (e.g., Slovic et al., 2000), Exemplar-Cueing Theory predicts that the subjective weight assigned may be affected by the frequency or probability format, (...) and how easily examples of the event, i.e., ‘exemplars’, are generated from linguistic cues that frame the match in light of further evidence (Koehler & Macchi, 2004). This paper presents two juror research studies to examine the difficulties that jurors have in assigning appropriate probative value to DNA evidence when contradictory evidence is presented. Study 1 showed that refuting evidence significantly reduced guilt judgments when exemplars were linguistically cued, even when the probability match and the refuting evidence had the same objective probative value. Moreover, qualitative reason for judgment responses revealed that interpreting refuting evidence was found to be complex and not necessarily reductive; refutation was found indicative of innocence or guilt depending on whether exemplars have been cued or not. Study 2 showed that the introduction of judges’ directions to linguistically cue exemplars, did not increase the impact of refuting evidence beyond its objective probative value, but less guilty verdicts were returned when jurors were instructed to consider all possible explanations of the evidence. The results are discussed in light of contradictory frequentist and exemplar-cueing theoretical positions, and their real-world consequences. (shrink)

In three empirical studies we examined how people reason about prior convictions in child abuse cases. We tested whether the disclosure of similar prior convictions prompts a mental representation or an additive probative value (Criminal Justice Act, 2003). Asymmetrical use of similar priors were observed in three studies. A pilot study showed that disclosure of a second prior did not contribute a weight equivalent to that of the first disclosure. Study 1 showed jurors did not see left-handed evidence (i.e. matching (...) victim bruising) as more indicative of guilt than right-handedness unless a prior conviction was present, and the presence of priors suppressed the generation of alternative possibilities indicative of innocence. Study 2 showed that disclosure did not decrease community ratings of reoffending propensity and dangerousness as much as a similar prior conviction increased them. We consider the results in the context of a new psychological theory of prior conviction bias and the consequences for the implementation of Section 100 of the Criminal Justice Act (2003). (shrink)

Each day people are presented with circumstances that may require speculation. Scientists may ponder questions such as why a star is born or how rainbows are made, psychologists may ask social questions such as why people are prejudiced, and military strategists may imagine what the consequences of their actions might be. Speculations may lead to the generation of putative explanations called hypotheses. But it is by checking if hypotheses accurately reflect the encountered facts that lead to sensible behaviour demonstrating a (...) true understanding. If evidence shows a hypothesis to be false, then people should rationally abandon it, especially if there are negative consequences. The aim of this thesis is to examine how effectively people search for evidence in their hypothesis testing to test whether or not their hypotheses are true or false in competitive games. -/- Research findings from six studies of hypothesis testing behaviour in competitive deductive tasks are explored. Chapter by chapter the thesis tests how everyday people, and master chess players, tackle hypothesis testing in mathematical tasks, such as how to solve sequential number sequence puzzles when thinking about an opponent, or how to solve chess problems in a variety of contexts. The implications of the results are discussed in light of aspects of general cognition: such as reasoning, social hypothesis testing and planning. (shrink)

This paper trials new experimental methods for the analysis of natural language reasoning and the development of critical ordinary language philosophy in the wake of J.L. Austin. Philosophical arguments and thought experiments are strongly shaped by default pragmatic inferences, including stereotypical inferences. Austin suggested that contextually inappropriate stereotypical inferences are at the root of some philosophical paradoxes and problems, and that these can be resolved by exposing those verbal fallacies. This paper builds on recent efforts to empirically document inappropriate stereotypical (...) inferences that may drive philosophical arguments. We demonstrate that previously employed questionnaire-based output measures do not suffice to exclude relevant confounds. We then report an experiment that combines reading time measurements with plausibility ratings. The study seeks to provide evidence of inappropriate stereotypical inferences from appearance verbs that have been suggested to lie at the root of the influential ‘argument from illusion’. Our findings support a diagnostic reconstruction of this argument. They provide the missing component for proof of concept for an experimental implementation of critical ordinary language philosophy that is in line with the ambitions of current ‘evidential’ experimental philosophy.

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean-style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. presented participants with two kinds of cases: Blocker cases and Non-Blocker cases. They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly (...) less agreed that seeing occurs. They thus hypothesized that folk intuitions better align with a no blocker condition than with a causal condition. This paper continues this line of enquiry with two new experiments. The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean-style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition. They also provide an empirical reason to doubt the reflection defense. (shrink)

The standard view in philosophy treats pains as phenomenally conscious mental states. This view has a number of corollaries, including that it is generally taken to rule out the existence of unfelt pains. The primary argument in support of the standard view is that it supposedly corresponds with the commonsense conception of pain. In this paper, we challenge this doctrine about the commonsense conception of pain, and with it the support offered for the standard view, by presenting the results of (...) a series of new empirical studies that indicate that lay people not only tend to believe that unfelt pains are possible, but actually, quite common.

Although mind-wandering research is rapidly progressing, stark disagreements are emerging about what the term “mind-wandering” means. Four prominent views define mind-wandering as 1) task-unrelated thought, 2) stimulus-independent thought, 3) unintentional thought, or 4) dynamically unguided thought. Although theorists claim to capture the ordinary understanding of mind-wandering, no systematic studies have assessed these claims. Two large factorial studies present participants (n=545) with vignettes that describe someone’s thoughts and ask whether her mind was wandering, while systematically manipulating features relevant to the four (...) major accounts of mind-wandering. Dynamics explains between four and twenty times more variance in participants’ mind-wandering judgments than other features. Our third study (n=153) tests and supports a unique prediction of the dynamic framework—obsessive rumination contrasts with mind-wandering. Our final study (n=277) used vignettes that resemble mind-wandering experiments. Dynamics had significant and large effects, while task-unrelatedness was insignificant. These results strongly align with the dynamic conception of mind-wandering. (shrink)

Testimonies about aphantasia are still surprisingly rare, more than a century after Galton. It is therefore difficult to understand how a person devoid of (a kind of) imagination actually thinks. In order to outline "what it is like" to be aphantasic, I will start by compiling two qualitative interviews with aphantasics that I will then compare with other testimonies collected in literature and online. The fact that aphantasia is poorly documented may also explain why few philosophers (with the notable exception (...) of Phillips 2014) seem to take this phenomenon seriously – contrary to others phenomena such as blindsight for instance. To redress the balance, the second part of this paper will consider three debates to which aphantasia could contribute. (shrink)

This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...) stereotypical inferences which are contextually inappropriate. We analyse a classical paradox about perception, suggest it relies on contextually inappropriate stereotypical inferences from appearance-verbs, and show that the conditions we identified as leading to contextually inappropriate stereotypical inferences are met in formulations of the paradox. Three experiments use a forced-choice plausibility-ranking task to document the predicted inappropriate inferences, in English, German, and Japanese. The cross-linguistic study allows us to assess the wider relevance of the proposed analysis. Our findings open up new perspectives for ‘evidential’ experimental philosophy. (shrink)

This chapter analyses the prospects of using neuroimaging methods, in particular functional magnetic resonance imaging (fMRI), for philosophical purposes. To do so, it will use two case studies from the field of emotion research: Greene et al. (2001) used fMRI to uncover the mental processes underlying moral intuitions, while Lindquist et al. (2012) used fMRI to inform the debate around the nature of a specific mental process, namely, emotion. These studies illustrate two main approaches in cognitive neuroscience: Reverse inference and (...) ontology testing, respectively. With regards to Greene et al.’s study, the use of Neurosynth (Yarkoni 2011) will show that the available formulations of reverse inference, although viable a priori, seem to be of limited use in practice. On the other hand, the discussion of Lindquist et al.’s study will present the so far neglected potential of ontology-testing approaches to inform philosophical questions. (shrink)

The standard view of pains among philosophers today holds that their existence consists in being experienced, such that there can be no unfelt pains or pain hallucinations. The typical line of support offered for this view is that it corresponds with the ordinary or commonsense conception of pain. Despite this, a growing body of evidence from experimental philosophers indicates that the ordinary understanding of pain stands in contrast to the standard view among philosophers. In this paper, we will survey this (...) literature and add to it, detailing the results of seven new studies on the ordinary understanding of pain using both corpus analysis and questionnaire methods.

In a series of articles in this journal, Michael Tye and Paul Noordhof have sparred over the correct explanation of the putative invalidity of the following argument: the pain is in my fingertip; the fingertip is in my mouth; therefore, the pain is in my mouth. Whereas Tye explains the failure of the argument by stating that “pain “creates an intensional context, Noordhof maintains that the “in” in ‘the pain is in my fingertip’ is not spatial, but has state-attributing character. (...) In this paper, we offer a third account, explaining the failure of the argument through state-attributing pragmatic implicatures. Empirical evidence is provided in support of this account.

Categorization and decision making are combined in a task with photorealistic faces. Two different types of face stimuli were assigned probabilistically into one of two fictitious groups; based on the category, faces were further probabilistically assigned to be hostile or friendly. In Part I, participants are asked to categorize a face into one of two categories, and to make a decision concerning interaction. A Markov model of categorization followed by decision making provides reasonable fits to Part I data. A Markov (...) model predicting decision making followed by categorization is rejected. In Part II, a no-parameter model predicts decisions using categorization and decision responses collected in separate trials, suggesting that Part 1 results are not an artifact of the presentation of categorization and decision questions within a single trial. Decisions concerning interaction appear to be based on information from the category decision, and not from the face stimuli alone. (shrink)

Critical thinking and values are fundamental topics of interest in higher education. The current study is an empirical validation of a university’s effort to teach students to apply critical thinking to the recognition and articulation of values contained in focal essays. A Critical Thinking about Values Assessment is provided, which evaluates students’ responses regarding key components of critical thinking, and “critical thinking about values,” in response to the essays. These two criteria were assessed at the beginning and end of the (...) semester as part of a naturally-occurring quasiexperiment. Results provide some support for the reliability and validity of the CTVA and suggest that the program has a tenuous relationship with students’ critical thinking, but a moderate to strongrelationship with students’ ability to recognize and articulate values.

The standard interpretation of quantum mechanics and a standard interpretation of the awareness of pain have a common feature: Both postulate the existence of an irresolvable duality. Whereas many physicists claim that all particles exhibit particle and wave properties, many philosophers working on pain argue that our awareness of pain is paradoxical, exhibiting both perceptual and introspective characteristics. In this chapter, we offer a pessimistic take on the putative paradox of pain. Specifically, we attempt to resolve the supposed paradox by (...) undermining the reasons offered for accepting the introspective side of the dualism. (shrink)

The aim of this paper is to argue that there has been some mismatch between the naturalist rhetoric of experimental philosophy and its actual practice: experimental philosophy is not necessarily, and not even paradigmatically, a naturalistic enterprise. To substantiate this claim, a case study is given for what genuinely naturalist experimental philosophy would look like.

We review different analytic approaches to narratives by those with psychopathological conditions, and we suggest that the interpretation of such narratives are complicated by a variety of phenomenological and hermeneutical considerations. We summarize an empirical study of narrative distance in narratives by non-pathological subjects, and discuss how the results can be interpreted in two different ways with regard to the issue of dissociation.

Some recent evidence has suggested that perspective taking skills in everyday life situations may differ across cultural groups. In the present study, we investigated this effect via culture priming in a group of Chinese-English bilingual adults in the context of a communication game. Results showed that the participants made more perspective taking errors when interpreting the game instruction under the Western than the Chinese primes. The findings suggest that the ability to assume others' mental states not only can be used (...) strategically but is also influenced by the currently active cultural frame in the mind of the bilingual. The present study provides the first evidence for a cultural effect on perspective taking using a within-sample approach via culture priming. (shrink)

There are two primary traditions in philosophical theorizing about moral standing—one emphasizing Experience (the capacity to feel pain and pleasure) and one emphasizing Agency (complexity of cognition and lifestyle). In this article we offer an explanation for this divide: Lay judgments about moral standing depend importantly on two independent cues (Experience and Agency), and the two philosophical traditions reflect this aspect of folk moral cognition. In support of this two-source hypothesis, we present the results of a series of new experiments (...) providing evidence for our account of lay judgments about moral standing, and argue that these results lend plausibility to the proposed causal link between folk moral cognition and the philosophical traditions.

We report the results of a cross-cultural investigation of person-body reasoning in the United Kingdom and northern Brazilian Amazon (Marajó Island). The study provides evidence that directly bears upon divergent theoretical claims in cognitive psychology and anthropology, respectively, on the cognitive origins and cross-cultural incidence of mind-body dualism. In a novel reasoning task, we found that participants across the two sample populations parsed a wide range of capacities similarly in terms of the capacities’ perceived anchoring to bodily function. Patterns of (...) reasoning concerning the respective roles of physical and biological properties in sustaining various capacities did vary between sample populations, however. Further, the data challenge prior ad-hoc categorizations in the empirical literature on the developmental origins of and cognitive constraints on psycho-physical reasoning (e.g., in afterlife concepts). We suggest cross-culturally validated categories of “Body Dependent” and “Body Independent” items for future developmental and cross-cultural research in this emerging area. (shrink)

In this study, we examine the belief bias effect in syllogistic reasoning under both standard presentation and in a condition where participants are required to respond within 10 seconds. As predicted, the requirement for rapid responding increased the amount of belief bias observed on the task and reduced the number of logically correct decisions, both effects being substantial and statistically significant. These findings were predicted by the dual-process account of reasoning, which posits that fast heuristic processes, responsible for belief bias, (...) compete with slower analytic processes that can lead to correct logical decisions. Requiring rapid responding thus differentially inhibits the operation of analytic reasoning processes, leading to the results observed. (shrink)

Seamon, Luo, and Gallo reported evidence that nonconscious processes could produce false recognition in a converging-associates task, whereby subjects falsely remember a nonstudied lure after studying a list of related words . Zeelenberg, Plomp, and Raaijmakers failed to observe this false recognition effect when list word recognition was at chance. We critically evaluate the evidence for nonsconscious processing and report the results of a new experiment designed to overcome previous methodological limitations. Consistent with Seamon et al., we found that conscious (...) activation of a related lure during study was not necessary for its subsequent recognition; consistent with Zeelenberg et al., we found no evidence for recognition of related lures under conditions where there was no memory for studied words. It is currently unknown whether conscious recollection of the studied items is necessary for false recognition or if nonconscious activation of the lure is sufficient. (shrink)

In philosophical thought experiments, as in ordinary discourse, our understanding of verbal case descriptions is enriched by automatic comprehension inferences. Such inferences have us routinely infer what else is also true of the cases described. We consider how such routine inferences from polysemous words can generate zombie intuitions: intuitions that are ‘killed’ (defeated) by contextual information but kept cognitively alive by the psycholinguistic phenomenon of linguistic salience bias. Extending ‘evidentiary’ experimental philosophy, this paper examines whether the ‘zombie argument’ against materialism (...) is built on zombie intuitions. We examine the hypothesis that contextually defeated stereotypical inferences from the noun ‘zombie’ influence intuitions about ‘philosophical zombies’. We document framing effects (‘zombie’ vs ‘duplicate’) predicted by the hypothesis. Findings undermine intuitions about the conceivability of ‘philosophical zombies’ and address the philosophical ‘hard problem of consciousness’. Findings support a deflationary response: The impression that principled obstacles prevent scientific explanation of how physical processes give rise to conscious experience is generated by philosophical arguments that rely on epistemically deficient intuitions.

The present research (total N = 2,057) tested whether people’s folk conception of consciousness aligns with the notion of a “Cartesian Theater” (Dennett, 1991). More precisely, we tested the hypotheses that people believe that consciousness happens in a single, confined area (vs. multiple dispersed areas) in the human brain, and that it (partly) happens after the brain finished analyzing all available information. Further, we investigated how these beliefs arerelated to participants’ neuroscientific knowledge as well as their reliance on intuition, and (...) which rationale they use to explain their responses. Using a computer-administered drawing task, we found that participants located consciousness, but not unrelated neurological processes (Studies 1a & 1b) or unconscious thinking (Study 2) in a single, confined area in the prefrontal cortex, and that they considered most of the brain not involved in consciousness. Participants mostly relied on their intuitions when responding, and they were not affected by prior knowledge about the brain. Additionally, they considered the conscious experience of sensory stimuli to happen in a spatially more confined area than the corresponding computational analysis of these stimuli (Study 3). Furthermore, participants’ explicit beliefs about spatial and temporal localization of consciousness (i.e., consciousness happening after the computational analysis of sensory information is completed) are independent, yet positively correlated beliefs (Study 4). Using a more elaborate measure for temporal localization of conscious experience, our final study confirmed that people believe consciousness to partly happen even after information processing is done (Study 5).

In a recent paper in this journal, David Chalmers introduced the meta-problem of consciousness as “the problem of explaining why we think consciousness poses a hard problem” (Chalmers, 2018, p. 6). A solution to the meta-problem could shed light on the hard problem of consciousness. In particular, it would be relevant to elucidate whether people’s problem intuitions (i.e. intuitions holding that conscious experience cannot be reduced to physical processes) are driven by factors related to the nature of consciousness, or rather (...) by factors that are independent of consciousness. Whether people hold problem intuitions, and what factors drive those intuitions, are largely empirical questions. However, there is a lack of empirical research on these issues to date. The results of four studies will show that (1) problem intuitions are not widespread, and (2) when they arise, they do so because of factors that are unrelated to the nature of consciousness. This suggests that consciousness is, after all, not so problematic. (shrink)

The studies we report indicate that it is possible to manipulate explicit ascriptions of consciousness by manipulating whether an agent’s behavior is deterministically caused. In addition, we explore whether this impact of determinism on consciousness is direct, or mediated by notions linked to agency – notions like moral responsibility, free will, deliberate choice, and sensitivity to moral reasons. We provide evidence of mediation. This result extends work on attributions of consciousness and their connection to attributions of agency by Adam Arico, (...) Brian Fiala, and Shaun Nichols (Arico et al. 2011, Fiala et al. 2014) and supports it against recent criticisms (e.g., Sytsma 2014). (shrink)

The meta-problem is 'the problem of explaining why we think that there is a problem of consciousness' (Chalmers, 2018, p. 6). This presupposes that we think there is a problem in the first place. We challenge the breadth of this 'we', arguing that there is already sufficient empirical evidence to cast doubt on the claim. We then add to this body of evidence, presenting the results of a new cross-cultural study extending the work of Sytsma and Machery (2010).

While philosophers and scientists sometimes suggest (or take for granted) that consciousness is an essential condition for free will and moral responsibility, there is surprisingly little discussion of why consciousness (and what sorts of conscious experience) is important. We discuss some of the proposals that have been offered. We then discuss our studies using descriptions of humanoid robots to explore people’s attributions of free will and responsibility, of various kinds of conscious sensations and emotions, and of reasoning capacities, and examine (...) the relationships between these attributions. Our initial results suggest that people’s attributions of free will are strongly influenced by their attributions of conscious emotions, such as happiness and disappointment, including Strawsonian emotions, such as pride and regret. These results provide some support for an intriguing proposal: Free will requires the capacity to make decisions that really matter to the agent, and for anything to really matter to the agent, she must be able to consciously experience the good and bad effects of the decisions she makes—to suffer and regret, or to enjoy and feel proud of, their outcomes.

The opinions that people hold about the nature of consciousness are important not only to researchers in philosophy and science, but also in many professional fields such as clinical medicine, law, and education. However, in spite of this importance and how controversial the topic is, there is remarkably little empirical data concerning what these opinions are. Here we describe the results of a multi-year survey of university students concerning their beliefs about the nature of consciousness and about what entities are (...) conscious. We find that these students are split fairly evenly between dualists and materialists, and that they also include a significant number of idealists. Almost all of the participants attribute consciousness to other people, and the vast majority attributes it to at least some animal species but not to computers. These results, especially when combined with those from the few existing previous surveys that we review, do not support past statements in the consciousness studies literature that dualism is by far the dominant viewpoint in the general population. The results also indicate that most people resolve the problem of other minds in a way that includes some animals as being conscious. (shrink)

Leading researchers in the philosophy of mind present and explore cutting edge research in the exciting new field of experimental philosophy.

People’s folk theory of consciousness encompasses three prototypes of conscious mental functioning: monitoring (awareness), choice, and subjective experience. All three are embedded in a broader folk theory of mind and thus closely linked to the concept of intentionality, action explanation, and a conception of free will. At least some of the prototypes of consciousness play a critical role in the assignment of personhood and responsibility. Recent discussions question the viability of folk conceptions of consciousness in light of work on the (...) unconscious and neuroscience. Thus far this work appears to complement folk conceptions without contradicting them. (shrink)

Mind, Consciousness and Body -/- We do not know how to think with or about these notions and others such as reality, perception, space, time, etc… In the following I will deal with the umbrella notions of mind, consciousness and body. The contents is relevant, but of greater importance is the manner or method in which I deal with these notions. I first present as an illustration of my approach or method, how I have dealt with the notions of intuition (...) and intuiting. One of the points I am trying to make is that: we do not know how to think about many things, for example mind, consciousness, awareness, body, intuition, etc. Therefore, I attempt to explore a number of things that we must investigate and deal with before we use these and other notions, as if they are clearly defined terms, before we try to use them to think and to think about anything, especially many leveled and multi- dimensional issues and problems such as the workings of ‘the mind, the body, intuition, consciousness and the relationship, if there are any, between these and other things. Then I suggest the initial steps for a few very basic requirements before the exploration of a theory of embodied, living, conscious tissues and a model for embodied (self-) consciousness research.

Given the hard problem of consciousness (Chalmers, 1995) there are no brain electrophysiological correlates of the subjective experience (the felt quality of redness or the redness of red, the experience of dark and light, the quality of depth in a visual field, the sound of a clarinet, the smell of mothball, bodily sensations from pains to orgasms, mental images that are conjured up internally, the felt quality of emotion, the experience of a stream of conscious thought or the phenomenology of (...) thought). However, there are brain occipital and left temporal electrophysiological correlates of the subjective experience (Pereira, 2015). Notwithstanding, as evoked signal, the change in event-related brain potentials phase (frequency is the change in phase over time) is instantaneous, that is, the frequency will transiently be infinite: a transient peak in frequency (positive or negative), if any, is instantaneous in electroencephalogram averaging or filtering that the event-related brain potentials required and the underlying structure of the event-related brain potentials in the frequency domain cannot be accounted, for example, by the Wavelet Transform (WT) or the Fast Fourier Transform (FFT) analysis, because they require that frequency is derived by convolution rather than by differentiation. However, as I show in the current original research report, one suitable method for analyse the instantaneous change in event-related brain potentials phase and accounted for a transient peak in frequency (positive or negative), if any, in the underlying structure of the event-related brain potentials is the Empirical Mode Decomposition with post processing (Xie et al., 2014) Ensemble Empirical Mode Decomposition (postEEMD) and Hilbert-Huang Transform (HHT).

The view that phenomenally conscious robots are on the horizon often rests on a certain philosophical view about consciousness, one we call “nomological behaviorism.” The view entails that, as a matter of nomological necessity, if a robot had exactly the same patterns of dispositions to peripheral behavior as a phenomenally conscious being, then the robot would be phenomenally conscious; indeed it would have all and only the states of phenomenal consciousness that the phenomenally conscious being in question has. We experimentally (...) investigate whether the folk think that certain (hypothetical) robots made of silicon and steel would have the same conscious states as certain familiar biological beings with the same patterns of dispositions to peripheral behavior as the robots. Our findings provide evidence that the folk largely reject the view that silicon-based robots would have the sensations that they, the folk, attribute to the biological beings in question. (shrink)

First, what are the psychological roots of our concept of free will? Second, how might progress on the first question contribute to progress regarding normative debates about the proper concept of free will? In sections two and three I address the first question. Section two discusses recent work in the experimental philosophy of free will, and motivates the study I report in section three. Section four reflects on the second question in light of the reported results. To preview, the results (...) suggest that the psychological structure of our concept of free will is sensitive to three independent features: Liberty, Ensurance, and Consciousness. I argue this supports the view that our concept is incompatibilist more than the view that our concept is compatibilist, and I discuss two proposals regarding the normative upshot. On one proposal, these results might be taken to offer some support to incompatibilism about the proper concept. A second proposal, however, makes room for a much different upshot. (shrink)

Seminal work in moral neuroscience by Joshua Greene and colleagues employed variants of the well-known trolley problems to identify two brain networks which compete with each other to determine moral judgments. Greene interprets the tension between these brain networks using a dual process account which pits deliberative reason against automatic emotion-driven intuitions: reason versus passion. Recent neuroscientific evidence suggests, however, that the critical tension that Greene identifies as playing a role in moral judgment is not so much a tension between (...) reason and passion, but a tension between distinct forms of deliberative reasoning: analytic versus empathetic. In this paper we present results from several new studies supporting this alternative hypothesis. (shrink)

Experimental philosophy is a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy. The present review focuses on research in experimental philosophy on four central questions. First, why is it that people's moral judgments appear to influence their intuitions about seemingly nonmoral questions? Second, do people think that moral questions have objective answers, or do they see morality as fundamentally relative? Third, do people believe in free will, and do they see free (...) will as compatible with determinism? Fourth, how do people determine whether an entity is conscious? (shrink)

In the first section, Introduction, we present our experimental design. In the second section, we characterize the grand average occipital and temporal electrical activity correlated with a contrast in access. In the third section, we characterize the grand average occipital and temporal electrical activity correlated with a contrast in phenomenology and conclude characterizing the grand average occipital and temporal electrical activity co-occurring with unconsciousness.

In a recent paper, Gray, Knickman, and Wegner present three experiments which they take to show that people perceive patients in a persistent vegetative state to have less mentality than the dead. Following on from Gomes and Parrott, we provide evidence to show that participants' responses in the initial experiments are an artifact of the questions posed. Results from two experiments show that, once the questions have been clarified, people do not ascribe more mental capacity to the dead than to (...) PVS patients. There is no reason to think that people perceive PVS patients as more dead than dead. (shrink)

Many philosophers and brain scientists hold that explaining consciousness is one of the major outstanding problems facing modern science today. One type of consciousness in particular—phenomenal consciousness—is thought to be especially problematic. The reasons given for believing that this phenomenon exists in the first place, however, often hinge on the claim that its existence is simply obvious in ordinary perceptual experience. Such claims motivate the study of people's intuitions about consciousness. In recent years a number of researchers in experimental philosophy (...) of mind have begun to shed light on this area, investigating how people understand and attribute those mental states that have been thought to be phenomenally conscious. In this article, we discuss the philosophical concept of phenomenal consciousness and detail the work that has been done on the question of whether lay people have this concept. (shrink)
