Common methods for analysing response time (RT) tasks, frequently used across different disciplines of psychology, suffer from a number of limitations such as the failure to directly measure the underlying latent processes of interest and the inability to take into account the uncertainty associated with each individual's point estimate of performance. Here, we discuss a Bayesian hierarchical diffusion model and apply it to RT data. This model allows researchers to decompose performance into meaningful psychological processes and to account optimally for (...) individual differences and commonalities, even with relatively sparse data. We highlight the advantages of the Bayesian hierarchical diffusion model decomposition by applying it to performance on Approach–Avoidance Tasks, widely used in the emotion and psychopathology literature. Model fits for two experimental data-sets demonstrate that the model performs well. The Bayesian hierarchical diffusion model overcomes important limitations of current analysis procedures and provides deeper insight in latent psychological processes of interest. (shrink)

In this commentary, we assess the propositional approach to associative learning not only in terms of veridicality and falsifiability, but also in heuristic value. We remark that it has furthered our knowledge and understanding of human, as well as animal, associative learning. At the same time, we maintain that models developed from the association formation tradition continue to bear great heuristic value as well.

Generalising what is learned about one stimulus to other but perceptually related stimuli is a basic behavioural phenomenon. We evaluated whether a rule learning mechanism may serve to explain such generalisation. To this end, we assessed whether inference rules communicated through verbal instructions affect generalisation. Expectancy ratings, but not valence ratings, proved sensitive to this manipulation. In addition to revealing a role for inference rules in generalisation, our study has clinical implications as well. More specifically, we argue that targeting inference (...) rules might prove to be an effective strategy to affect the excessive generalisation that is often observed in psychopathology. (shrink)

Two key research issues in the field of causal learning are how people acquire causal knowledge when observing data that are presented sequentially, and the level of abstraction at which learning takes place. Does sequential causal learning solely involve the acquisition of specific cause-effect links, or do learners also acquire knowledge about abstract causal constraints? Recent empirical studies have revealed that experience with one set of causal cues can dramatically alter subsequent learning and performance with entirely different cues, suggesting that (...) learning involves abstract transfer, and such transfer effects involve sequential presentation of distinct sets of causal cues. It has been demonstrated that pre-training can modulate classic causal learning phenomena such as forward and backward blocking. To account for these effects, we propose a Bayesian theory of sequential causal learning. The theory assumes that humans are able to consider and use several alternative causal generative models, each instantiating a different causal integration rule. Model selection is used to decide which integration rule to use in a given learning environment in order to infer causal knowledge from sequential data. Detailed computer simulations demonstrate that humans rely on the abstract characteristics of outcome variables to select a causal integration rule, which in turn alters causal learning in a variety of blocking and overshadowing paradigms. When the nature of the outcome variable is ambiguous, humans select the model that yields the best fit with the recent environment, and then apply it to subsequent learning tasks. Based on sequential patterns of cue-outcome co-occurrence, the theory can account for a range of phenomena in sequential causal learning, including various blocking effects, primacy effects in some experimental conditions, and apparently abstract transfer of causal knowledge.

Thousands of youth suffering from acquired brain injury or other early-life neurological disease live, mature, and learn with only limited communication and interaction with their world. Such cognitively capable children are ideal candidates for brain-computer interfaces. While BCI systems are rapidly evolving, a fundamental gap exists between technological innovators and the patients and families who stand to benefit. Forays into translating BCI systems to children in recent years have revealed that kids can learn to operate simple BCI with proficiency akin (...) to adults. BCI could bring significant boons to the lives of many children with severe physical impairment, supporting their complex physical and social needs. However, children have been neglected in BCI research and a collaborative BCI research community is required to unite and push pediatric BCI development forward. To this end, the pediatric BCI Canada collaborative network was formed, under a unified goal to cooperatively drive forward pediatric BCI innovation and impact. This article reflects on the topics and discussions raised in the foundational BCI-CAN meeting held in Toronto, ON, Canada in November 2019 and suggests the next steps required to see BCI impact the lives of children with severe neurological disease and their families.

ABSTRACTIndividual differences in fear generalisation have been proposed to play a role in the aetiology and/or maintenance of anxiety disorders, but few data are available to directly support that claim. The research that is available has focused mostly on generalisation of peripheral and central physiological fear responses. Far less is known about the generalisation of avoidance, the behavioural component of fear. In two experiments, we evaluated how neuroticism, a known vulnerability factor for anxiety, modulates an array of fear responses, including (...) avoidance tendencies, towards generalisation stimuli. Participants underwent differential fear conditioning, in which one conditioned stimulus was repeatedly paired with an aversive outcome, whereas another was not. Fear generalisation was observed across measures in Experiment 1 and Experiment 2, with overall highest responding to the CS+, lowest to the CS− and intermediate responding to the GSs. Neuroticism had very little impact on fear generalisation, in line with the idea that fear generalisation is largely an adaptive process. (shrink)

ABSTRACTAffective states influence how individuals process information and behave. Some theories predict emotional congruency effects. Emotional congruency should theoretically obstruct the learning of reward associations and their ability to guide behaviour under negative mood. Two studies tested the effects of the induction of a negative affective state on appetitive Pavlovian learning, in which neutral stimuli were associated with chocolate or alcohol rewards. In both experiments, participants showed enhanced approach tendencies towards predictors of reward after a negative relative to a positive (...) performance feedback manipulation. This increase was related to a reduction in positive affect in Experiment 1 only. No effects of the manipulation on conditioned reward expectancies, craving, or consumption were observed. Overall, our findings support the idea of counter-regu... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:IntroductionGerhold K. BeckerThe concept of personhood has been a prime focus in contemporary bioethics. Three areas of ethical decision making in particular have been addressed through explorations into the conditions and criteria of personhood: the beginning and the end of human life and the morally relevant boundaries that separate human beings from nonhuman animals. Blending theology with science fiction, the scope of the latter area has been expanded further (...) to include entities ranging from gods, angels, and extraterrestrials all the way down to machines. Although the recognition of personhood traditionally has been based on metaphysical and ontological considerations about sets of (psychological and cognitive) person-making properties, the emphasis is now squarely placed on moral concerns. Simply put, from a moral perspective a person is someone morally considerable who is the subject of moral rights and merits moral protection. The implications of the conferral of person status for moral decision making in medicine, health care, and research are, however, less clear. Problems arise from the fact that the traditional concept of personhood is constituted by three rather different ideas. As David Wiggins has pointed out, the concept of personhood combines in a single focus the ideas of the person as object of science (biological, neurophysiological, and so forth), as subject of consciousness and experience, and as locus of value and moral attributes. It is therefore extremely difficult to neatly separate metaphysical personhood from moral personhood, and vice versa, and to draw morally relevant conclusions without continuously moving back and forth between the different constitutive factors. Thus, moral rights seem to presuppose moral agency, and moral agency is contingent on personal identity, which in turn presupposes some form of physical (including psychological) existence. It is obvious, that differences in the analysis of any one of these constituents of personhood will result in different conceptions of personhood with different implications for ethical decision making. Bioethical disputes about the moral status of human fetuses or of irreversibly comatose patients, as well as of the great apes [End Page 289] and other animals, are notoriously complex because they involve fundamental disagreements about personhood and the most promising strategies for their resolution. Although this has led some to question the usefulness of the concept of personhood for bioethics altogether, others seek remedy through the analysis of moral agency within the context of particular bioethical issues.The essays in this volume clearly reflect the current state of the bioethical debate on personhood and are representative of its major strands. They evolved from discussions at an international symposium on Bioethics and the Concept of Personhood at the Centre for Applied Ethics, Hong Kong Baptist University, May 1998, that explored the bioethical implications of the concept of personhood in a historical and cross-cultural perspective.In the opening essay, John Harris gives Locke’s concept of person a new twist by reading his list of criteria of personhood as preconditions of a being’s capability to value his or her own existence. The status of person is contingent upon the possession of the capacity to value one’s own existence; whoever is capable of such valuation is a person (as long such capacity actually exists) and makes moral claims on other persons. On this account, personhood is not co-extensive with human life or the human species, and even transcends other forms of organic life. Harris allows for the possibility that some machines in effect might qualify for person status. Although human life develops gradually and with it the capacity to value existence, Harris rejects both the potentiality argument and gradualism on the grounds that personhood is a “threshold” concept. Accordingly, proximity to the threshold is morally insignificant, and everything depends on actually crossing the threshold.Tom Beauchamp takes issue with what he sees as the dominant trend in contemporary bioethics to derive moral conclusions from metaphysical accounts of personhood. On his reading, metaphysical theories of personhood are abused in normative analysis by employing certain sets of psychological or cognitive properties to identify persons as bearers of moral rights. He argues that by themselves, without the incorporation of independent moral principles, such properties have no moral implications and cannot confer moral standing. Thus, a being may... (shrink)

Mitochondrial function and biogenesis depend on the transport of a large variety of proteins, ions, and metabolites across the two surrounding membranes. While several specific transporters are present in the inner membrane, transport processes across the outer membrane are less understood. Recent studies reveal that the number of outer membrane channels and their transport mechanisms are more diverse than originally thought. Four protein‐conducting channels promote transport of distinct sets of precursor proteins across and into the outer membrane. The voltage‐dependent anion (...) channel (VDAC) forms the major channel for small hydrophilic molecules. In addition, three channels with yet unknown substrate specificity exist in the outer membrane. In this review, we outline the emerging functional diversity, selectivity, and regulation of mitochondrial outer membrane channels. The presence of several channel‐forming proteins challenges the traditional view that the outer membrane forms an unspecific size‐exclusion filter for the flux of small hydrophilic molecules.

An existential psychodynamic theory is presented based on Ernest Becker's claim that self‐esteem and cultural worldviews function to ameliorate the anxiety associated with the uniquely human awareness of vulnerability and mortality. Psychological equanimity is hypothesized to require (1) a shared set of beliefs about reality that imbues the universe with stability, meaning, and permanence; (2) standards by which individuals can judge themselves to be of value; and (3) promises of safety and the transcendence of death to those who meet the (...) standards of value. An empirical research program in support of this theory is then described, and the personal and interpersonal implications of these ideas are briefly considered. (shrink)

Sheldon Solomon, Jeff Greenberg, and Tom Pyszczynski offer experimental confirmation for Ernest Becker's claim that the fear of death is a powerful unconscious motive producing polarized worldviews and scapegoating. Their suggestion that their findings also prove Sigmund Freud's theory of repression, with worldviews as its irrational products, is questionable, although Becker's own statements about worldviews as “illusions” seem to invite such interpretation. Their basic theory does not depend on this, however, and abandoning it would enable them to take better advantage (...) of their finding that worldviews incorporating the values of rationality and tolerance tend to counteract polarization effects.

Quantum mechanics is humanity's finest scientific achievement. It explains why the sun shines and how your eyes can see. It's the theory behind the LEDs in your phone and the nuclear hearts of space probes. Every physicist agrees quantum physics is spectacularly successful. But ask them what quantum physics means, and the result will be a brawl. At stake is the nature of the Universe itself. What does it mean for something to be real? What is the role of consciousness (...) in the Universe? And do quantum rules apply to very small objects like electrons and protons, but not us? In What is Real?, Adam Becker brings to vivid life the brave researchers whose quest for the truth led them to challenge Bohr: David Bohm, who picked up Einstein's mantle and sought to make quantum mechanics deterministic, all while being hounded by the forces of McCarthyism; Hugh Everett, who argued that everything, big and small, must be governed by the same rules; and John Bell, who went to great lengths to eradicate the power of the god-like observer from the core of quantum physics. And they paid dearly, their reputations, careers, and sometimes lives ruined completely. But history has been kinder to them than their contemporaries were. As Becker shows, the brave intellectual giants have inspired a growing army of physicists and philosophers intent both on making a philosophically more satisfying theory of the universe and a more useful one as well. A gripping story of some of humanity's greatest ideas and the high cost with which many have pursued them, What is Real? is intellectual history at its passionate best. (shrink)

In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

It is an important feature of creatures like us that our various motivations compete for control over our behaviour, including mental behaviour such as imagining and attending. In large part, this competition is adjudicated by the stimulation of affect — the intrinsically pleasant or unpleasant aspects of experience. In this paper I argue that the motivation-affect system controls a sub-type of attention called 'alerting attention' to bring various goals and stimuli to consciousness and thereby prioritize those contents for action. This (...) view allows me to flesh out the global workspace theory of consciousness, as well as some of the phenomenal characteristics of conscious experience. (shrink)

To understand Self-Representationalism you need to understand its family. Self-Representationalism is a branch of the Meta-Representationalist family, and according to theories in this family what distinguishes conscious mental representations from unconscious mental representations is that conscious ones are themselves the target of a mental meta¬-representational state. A mental state M1 is thus phenomenally conscious in virtue of being suitably represented by some mental state M2. What distinguishes the Self-Representationalist branch of the family is the claim that M1 and M2 must (...) be the same token mental state, so a mental state is phenomenally conscious in virtue of suitably representing itself. This Self-Representationalist branch of the family divides into further branches, giving us specific implementations of the Self-Representationalist approach. But before asking whether we should adopt Self-Representationalism, and in what form, we should reflect on why Meta-Representationalism is an attractive family in the first place. After all, Self-Representationalist theories trade on their family name, claiming to deliver on the promises that drive the Meta-Representationalist approach. The two most important promises of Meta-Representationalism are: a) the promise of capturing the transitivity of consciousness and; b) the promise of rendering consciousness naturalisable. I discuss each in turn. (shrink)

Abstract Temporal Externalism is the view that future events can contribute to determining the present content of our thoughts and utterances. Two objections to Temporal Externalism are discussed and rejected. The first is that Temporal Externalism has implausible consequences for the epistemology of biology and other taxonomic sciences (Brown, 2000). The second is that it is committed to implausible claims about dispositions.

If we were to connect two individuals’ brains together, how would this affect the individuals’ conscious experiences? In particular, it is possible for two people to share any of their conscious experiences; to simultaneously enjoy some token experiences while remaining distinct subjects? The case of the Hogan twins—craniopagus conjoined twins whose brains are connected at the thalamus—seems to show that this can happen. I argue that while practical empirical methods cannot tell us directly whether or not the twins share conscious (...) experiences, considerations about the locality of content processing in the brain entails that they most likely do so.

How wrong is it to deceive someone into sex by lying, say, about one's profession? The answer is seriously wrong when the liar's actual profession would be a deal breaker for the victim of the deception: this deception vitiates the victim's sexual consent, and it is seriously wrong to have sex with someone while lacking his or her consent.

Der Band untersucht rhetorische Strategien der emotionalen Kommunikation in Partnerwerbungsgesprächen. Ausgehend von der Annahme, dass eine bewusste Steuerung emotionaler Gesprächsprozesse durch einen strategischen Kommunikator die Erreichung des angestrebten Ziels wahrscheinlicher macht, geht er der Frage nach, welche Möglichkeiten sich in solchen Gesprächen bieten, mit Hilfe sprachlich-textlicher Mittel emotional zu überzeugen. Dabei konzentriert er sich - in Abgrenzung zu Studien emotionaler Körpersprache - ganz auf die verbale Seite der Kommunikation. Als Datenbasis dienen die Transkripte eines Korpus aus Face-to-Face-Gesprächen. Basierend auf einem (...) methodisch innovativen Ansatz zur Untersuchung des Verhältnisses von Sprache und Emotion, liefert der Band zahlreiche neue Erkenntnisse für die Rhetorik-, Emotions- und Gesprächsforschung.

In this essay we critically evaluate the progress that has been made in solving the problem of meaning in artificial intelligence (AI) and robotics. We remain skeptical about solutions based on deep neural networks and cognitive robotics, which in our opinion do not fundamentally address the problem. We agree with the enactive approach to cognitive science that things appear as intrinsically meaningful for living beings because of their precarious existence as adaptive autopoietic individuals. But this approach inherits the problem of (...) failing to account for how meaning as such could make a difference for an agent’s behavior. In a nutshell, if life and mind are identified with physically deterministic phenomena, then there is no conceptual room for meaning to play a role in its own right. We argue that this impotence of meaning can be addressed by revising the concept of nature such that the macroscopic scale of the living can be characterized by physical indeterminacy. We consider the implications of this revision of the mind-body relationship for synthetic approaches. (shrink)

Das Buch bietet eine systematische Aufarbeitung der Forschung zum moralpsychologischen Ansatz von Lawrence Kohlberg und insbesondere seiner zahlreichen Kritiker.

Deflationists believe that the question “What is truth?” should be answered not by means of a metaphysical inquiry into the nature of truth, but by figuring out what use we make of the concept of truth, and the word ‘true’, in practice. This article accepts this methodology, and it thereby rejects pluralism about truth that is driven by ontological considerations. However, it shows that there are practical considerations for a pluralism about truth, formulated at the level of use. The theory (...) expounded by this article states that truth is a dual-purpose tool; it can be used as a device for transferring justificatory burdens and, for select areas of discourse, it can also be used as a standard, a norm. This contrast in how truth is used introduces a bifurcation in our discourse that is reminiscent of metaphysical divides traced by more traditional versions of alethic pluralism. However, my pluralism “at the level of use” states that truth is plural solely at the level of use. It is unified at both the conceptual as well as the metaphysical level. At those levels, the theory takes its cue from deflationism. As such, this theory is offered as a midway point and as a potential way forward in the debate between deflationism and pluralism.

Kierkegaard understood his thinking as philosophy confronting its own end. In campaigning against the existential amnesia of the 19th century, he revived the intellectual figure of a kind of philosophizing with roots in both the Socratic method and the apophatic reflections of Meister Eckhart. The Young Hegelians philosophy of action thereby became action of the text. The aim: existentially to move the reader.".

This book adds impetus to the nexus between human rights, human rights education and material reality. The dissonance between these aspects is of growing concern for most human rights educators in various social contexts. The first part of the book opens up new discourses and presents new ontologies and epistemologies from scholars in human rights, human rights education and human rights literacies to critique and/or justify the understandings of human rights' complex applications. Today's rapidly changing social contexts and new languages (...) attempting to understand ongoing dehumanization and violations, put enormous pressure on higher education, educators, individuals working in social sciences, policy makers and scholars engaged in curricula making. The second part demonstrates how global interactions between citizens from different countries with diverse understandings of human rights (from developed and developing democracies) question the link between human rights and it's in(ex)clusive Western philosophies. Continuing inhumane actions around the globe reflect the failure of human rights law and human rights education in schools, higher education and society at large. The book shows that human rights education is no longer a blueprint for understanding human rights and its universal or contextual values presented for multicomplexial societies. The final chapters argue for new ontologies and epistemologies of human rights, human rights education and human rights literacies to open-up difficult conversations and to give space to dissonant and disruptive discourses. The many opportunities for human rights education and literacies lies in these conversations. (shrink)
