Steady-state visual evoked potentials are commonly used for functional objective diagnostics. In general, the main response at the stimulation frequency is used. However, some studies reported the main response at the second harmonic of the stimulation frequency. The aim of our study was to analyze the influence of the stimulus design on the harmonic components of ssVEPs. We studied 22 subjects using a circular layout. At a given eccentricity, the stimulus was presented according to a 7.5 Hz square wave with (...) 50% duty cycle. To analyze the influence of the stimulus eccentricity, a background luminance of 30 cd/m2 was added to suppress foveal stray light effects; to analyze the influence of simultaneous foveal and peripheral stimulations, stimulations are performed without stray light suppression. For statistical analysis, medians M of the amplitude ratios for amplitudes at the second harmonic to the first harmonic and the probability of the occurrence of the main response at the second harmonic P are calculated. For stimulations with foveal stray light suppression, the medians were M0–1.6° = 0.45, M1.6–3.5° = 0.45, M3.5–6.4° = 0.76, M6.4–10.9° = 0.72, and M10.9–18° = 0.48, and the probabilities were P0–1.6° = 0.05, P1.6–3.5° = 0.05, P3.5–6.4° = 0.32, P6.4–10.9° = 0.29, and P10.9–18° = 0.30. For stimulations without foveal stray light suppression, the medians M were M0–1.6° = 0.29, M1.6–3.5° = 0.37, M3.5–6.4° = 0.98, M6.4–10.9° = 1.08, and M10.9–18° = 1.24, and the probabilities were P0–1.6° = 0.09, P1.6–3.5° = 0.05, P3.5–6.4° = 0.50, P6.4–10.9° = 0.55, and P10.9–18° = 0.55. In conclusion, the stimulus design has an influence on the harmonic components of ssVEPs. An increase in stimulation eccentricity during extrafoveal stimulation leads to a transition of the main response to the second harmonic. The effect is enhanced by a simultaneous foveal stimulation.

Ethical approval must be obtained before medical research can start. We describe the differences in EA for an pseudonymous, non-interventional, observational European study. Sixteen European national coordinators of the international study on very old intensive care patients answered an online questionnaire concerning their experience getting EA. N = 8/16 of the NCs could apply at one single national ethical committee, while the others had to apply to various regional ECs and/or individual hospital institutional research boards. The time between applying for (...) EA and the first decision varied between 7 days and 300 days. In 9/16 informed consent from the patient was not deemed necessary; in 7/16 informed consent was required from the patient or relatives. The upload of coded data to a central database required additional information in 14/16. In 4/16 the NCs had to ask separate approval to keep a subject identification code list to de-pseudonymize the patients if questions would occur. Only 2/16 of the NCs agreed that informed consent was necessary for this observational study. Overall, 6/16 of the NCs were satisfied with the entire process and 8/16 were unsatisfied. 11/16 would welcome a European central EC that would judge observational studies for all European countries. Variations in the process and prolonged time needed to get EA for observational studies hampers inclusion of patients in some European countries. This might have a negative influence on the external validity. Further harmonization of ethical approval process across Europe is welcomed for low-risk observational studies. Getting ethical approval for low-risk, non-interventional, observational studies varies enormously across European countries. (shrink)

With the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), global researchers were confronted with major challenges. The German National Pandemic Cohort Network (NAPKON) was launched in fall 2020 to effectively leverage resources and bundle research activities in the fight against the coronavirus disease 2019 (COVID-19) pandemic. We analyzed the setup phase of NAPKON as an example for multicenter studies in Germany, highlighting challenges and optimization potential in connecting 59 university and nonuniversity study sites. We examined the ethics application (...) process of 121 ethics submissions considering durations, annotations, and outcomes. Study site activation and recruitment processes were investigated and related to the incidence of SARS-CoV-2 infections. For all initial ethics applications, the median time to a positive ethics vote was less than two weeks and 30 of these study sites (65%) joined NAPKON within less than three weeks each. Electronic instead of postal ethics submission (9.5 days (Q1: 5.75, Q3: 17) vs. 14 days (Q1: 11, Q3: 26), p value = 0.01) and adoption of the primary ethics vote significantly accelerated the ethics application process. Each study center enrolled a median of 37 patients during the 14-month observation period, with large differences depending on the health sector. We found a positive correlation between recruitment performance and COVID-19 incidence as well as hospitalization incidence. Our analysis highlighted the challenges and opportunities of the federated system in Germany. Digital ethics application tools, adoption of a primary ethics vote and standardized formal requirements lead to harmonized and thus faster study initiation processes during a pandemic. (shrink)

Pessoa (2013) makes an impressive case that emotion, motivation, and cognition are neurally intertwined. Our commentary broadens the discussion to the functional, “mind” level. We argue that philosophical and computational considerations justify some modern “separatist” views. We highlight several psychological phenomena that illustrate independence, including affective and motivational reactions to rudimentary inputs, and the guiding role of such reactions in cognition.

The traditional ascription of the Neoplatonic commentary on the De Anima to Sim­plicius has prominently been disputed by Carlos Steel and Fernand Bossier, along with J.O. Urmson and Francesco Piccolomini, among others. Citing problems with terminology, diction, cross-references, doctrine, and other features, these authors have argued that the commentary cannot have been composed by Simplicius and that Priscian of Lydia is a favored alternative. In this paper, I present some new arguments for why the traditional attribution to Simplicius is, in (...) fact, the correct one. In particular, while addressing some of the terminological facts that have also been discussed by Christina Luna, Peter Lautner, Patricia Huby, and Philippe Vallat,1 among others, I offer a more secure basis for identifying the author of the De Anima commentary with Simplicius than has so far been proposed. In place of the disputes regarding terminology, which the debate has largely centered upon, I argue that certain unique and characteristic interpretive procedures, which one only finds in the undisputed Simplician works, allow us to identify the authorship of the De Anima commentary with Simplicius securely. Further, comparison of these methodological features with the extant works of Priscian rules out the possibility of his authorship of the commentary. I also provide some suggestions for resolving a few remaining issues of cross-reference between the De Anima commentary and the rest of Simplicius’s work. Finally, I conclude with some words on how that particular form of harmonization pursued by Simplicius’s contemporaries differs from both that of the De Anima commentary as well as his other works.

In a world surrounded by smart objects from sensors to automated medical devices, the ubiquity of ‘smart’ seems matched only by its lack of clarity. In this article, we use our discussions with expert stakeholders working in areas of implantable medical devices such as cochlear implants, implantable cardiac defibrillators, deep brain stimulators and in vivo biosensors to interrogate the difference facets of smart in ‘implantable smart technologies’, considering also whether regulation needs to respond to the autonomy that such artefacts carry (...) within them. We discover that when smart technology is deconstructed it is a slippery and multi-layered concept. A device’s ability to sense and transmit data and automate medicine can be associated with the ‘sting’ of autonomy being disassociated from human control as well as affecting individual, group, and social environments.

As children gradually master grammatical rules, they often go through a period of producing form‐meaning associations that were not observed in the input. For example, 2‐ to 3‐year‐old English‐learning children use the bare form of verbs in settings that require obligatory past tense meaning while already starting to produce the grammatical –ed inflection. While many studies have focused on overgeneralization errors, fewer studies have attempted to explain the root of this earlier stage of rule acquisition. In this work, we use (...) computational modeling to replicate children's production behavior prior to the generalization of past tense production in English. We illustrate how seemingly erroneous productions emerge in a model, without being licensed in the grammar and despite the model aiming at conforming to grammatical forms. Our results show that bare form productions stem from a tension between two factors: (1) trying to produce a less frequent meaning (the past tense) and (2) being unable to restrict the production of frequent forms (the bare form) as learning progresses. Like children, our model goes through a stage of bare form production and then converges on adult‐like production of the regular past tense, showing that these different stages can be accounted for through a single learning mechanism.

The Knowledge Argument of Frank Jackson has not persuaded physicalists, but their replies have not dispelled the intuition that someone raised in a black and white environment gains genuinely new knowledge when she sees colors for the first time. In what follows, we propose an explanation of this particular kind of knowledge gain that displays it as genuinely new, but orthogonal to both physicalism and phenomenology. We argue that Mary’s case is an instance of a common phenomenon in which something (...) new is learned as the result of exploiting representational resources that were not previously exploited, and that this results in gaining genuinely new information.

Sometimes a police officer can only stop a fleeing suspect by striking or shooting him. When is it morally justified to use such force rather than let the suspect go? Beginning with deadly force, this article disentangles key considerations. First, it distinguishes justifications for force that are premised on a liability or forfeiture from justifications premised upon lesser-evils considerations. Second, it unpacks the distinct interests the state might claim in subduing suspects, from adjudicating suspects, to punishing criminals, to preventing crime. (...) Drawing these distinctions shows that the state’s interests are weaker than they first appear, rarely sufficient to outweigh the individual’s strong interests against force, and many suspects are not liable to the force to which they are subjected. Ultimately, we conclude (perhaps unsurprisingly) many legally permissible uses of force are morally unjustified. Finally, we turn to ways our analysis can be extrapolated to nondeadly force.

This paper focuses on the emotional make-up of Descartes’s generous person. Described as having complete control over the passions, the generous person is not passion-free; she feels compassion for those in need but unable to bear their misfortunes with fortitude, hates vice, takes satisfaction in her own virtue, etc. To bring to light the coherence of the generous person’s emotional configuration, a compare and contrast analysis with Descartes’s deficient moral type, the abject person, is provided. Real life as well as (...) literary examples (Queen Christina of Sweden, Descartes himself and Kadhy Demba, one of the main characters of Marie NDiaye’s novel Trois Femmes Puissantes) further refine the portrait of Descartes’s generous person and show that generosity is achievable by anyone who uses their will well. Descartes’s position on harmonizing the passions is reconstructed as a developmental trajectory: harmonizing the emotions is possible courtesy of God who put this sphere of created affairs under our jurisdiction; harmonizing the passions is required since the alternative is sub-optimal (souls enslaved and miserable); finally, harmonizing the emotions is satisfying. Since, as the above examples demonstrate, in the process of making their emotional composition coherent, different people take different routes and thus “create for themselves a personal, quite personal ideal,” acquiring Cartesian generosity points the way to Nietzsche’s later notion of self-creation.

Many philosophers of science believe that empirical psychology can contribute little to the philosophical investigation of explanations. They take this to be shown by the fact that certain explanations fail to elicit any relevant psychological events (e.g., familiarity, insight, intelligibility, etc.). We report results from a study suggesting that, at least among those with extensive science training, a capacity to render an event intelligible is considered a requirement for explanation. We also investigate for whom explanations must be capable of rendering (...) events intelligible and whether or not accuracy is also viewed as a requirement. (shrink)

Every day, television news operations have available dozens of video news releases (VNRs), public relations handout videos designed to mimic news formats. Electronic tracking indicates some of these VNRs are used. Critics typically assail VNRs on ethical grounds, that VNRs deceive audience members into thinking they are watching news gathered by reporters, rather than a promotional pitch. Using a snowball technique, the researchers presented survey respondents with authentic-looking local television news stories; 157 respondents evaluated three stories (out of nine). Some (...) stories used station-generated footage, some network, and some VNRs. Respondents were asked their best estimation of the source. The data indicated a real likelihood VNR deception is occurring. Two of the three VNRs deceived at least half the respondents. Respondents were incorrect an average of 46% of the time when attempting to identifying VNRs, compared to 29% incorrectly identifying network video and 20% incorrectly identifying locally shot video.

For more than a century, it has been a standard ploy to argue against relativism on the grounds of self-referential incoherence . This paper determines the particular form this sort of charge takes when applied to a problematic passage in which Kuhn defends his relativistic theory of science by applying that theory to the debate between his critics and hirnself. If Kuhn were to give up relativism with respect to facts and truth but retain it with respect to the strength (...) of reasons, a pair of dilemmas charging circularity andinconsistency could be circumvented.

Rather than dismissing mysticism as irrelevant to the study of medieval philosophy, this chapter identifies the two forms of mysticism most prevalent in the Middle Ages from the twelfth to the early fifteenth century - the apophatic and affective traditions - and examines the intersections of those traditions with three topics of medieval philosophical interests: the relative importance of intellect and will, the implications of the Incarnation for attitudes towards the human body and the material world, and the proper relation (...) between contemplation and activity in the good life.

In Aquinas's account of the beatific vision, human beings are joined to God in a never-ending act of contemplation of the divine essence: a state which utterly fulfills the human drive for knowledge and satisfies every desire of the human heart. In this paper, I argue that this state represents less a fulfillment of human nature, however, than a transcendence of that nature. Furthermore, what’s transcended is not incidental on a metaphysical, epistemological, or moral level.

Aquinas’s account of the human soul is the key to his theory of human nature. The soul’s nature as the substantial form of the human body appears at times to be in tension with its nature as immaterial intellect, however, and nowhere is this tension more evident than in Aquinas’s discussion of the ‘separated’ soul. In this paper I use the Biblical story of the rich man and Lazarus (which Aquinas took to involve actual separated souls) to highlight what I (...) will call the Two-Person Problem facing his account of human identity through death and the bodily resurrection. Aquinas claims that the rational soul is neither the human being nor the human person. When the rich man’s soul says “I am in agony,” then, what is the referent of “I?” It appears that there is a human person, ‘Dives,’ who is replaced at Dives’s death by the person ‘Dives’s soul,’ who is in turn replaced at the bodily resurrection by ‘Dives,’ whom Aquinas claims is numerically identical to the original person. But this seems hopeless as an identity-preserving account of human nature. I believe that Aquinas’s account of human nature does not, as it stands, possess the resources with which to overcome this difficulty; I conclude that reconstructing a(n otherwise) Thomistic account that involves immediate bodily resurrection, although a radical approach, is the one best suited to preserving the most essential features of Aquinas’s theory.

: This paper reviews current and suggested policies designed to increase organ donation in the United States and indicates the problems inherent to these approaches for increasing organ donation by African Americans. Data from a population-based study assessing attitudes and beliefs about organ donation among white and African-American respondents are presented and discussed. We pose the question of whether it is reasonable to maintain the existing system or whether we should institute a system that uses policies based on the attitudes (...) and beliefs of a minority group that is in greater need than the majority. In light of the discussion, we suggest that the current policies guiding the organ procurement system are not adequate to address existing concerns within the African-American community and that a different set of assumptions may be needed to drive organ procurement policy.

The ecofeminist argument for veganism is powerful. Meat consumption is a deeply gendered act that is closely tied to the systematic objectification of women and nonhuman animals. I worry, however, that presenting veganism as "the" moral ideal might reinforce rather than alleviate the disordered status quo in gendered eating, further disadvantaging women in patriarchal power structures. In this chapter, I advocate a feminist account of ethical eating that treats dietary choices as moral choices insofar as they constitute an integral part (...) of our relationships to ourselves and to others. I believe that we should think of dietary choices in Aristotelian moral terms as a mean relative to us, falling on a continuum between the vice of doing injustice to ourselves, on the one hand, and the vice of doing injustice to others, on the other. On this view, what it is moral to eat for individuals is not a fixed ideal, but rather depends on particulars of our physiological, psychological, economic, cultural, and relational situations.

Self-knowledge is a persistent—and paradoxical—theme in medieval mysticism, which portrays our ultimate goal as union with the divine. Union with God is often taken to involve a cognitive and/or volitional merging that requires the loss of a sense of self as distinct from the divine. Yet affective mysticism—which emphasizes the passion of the incarnate Christ and portrays physical and emotional mystical experiences as inherently valuable—was in fact the dominant tradition in the later Middle Ages. An examination of both the affective (...) and apophatic traditions demonstrates that, in addition to constituting a necessary stage on the path toward union with the divine, self-knowledge in medieval mysticism was seen not just as something to be transcended, but (particularly in the works of female mystics) as a means of overcoming alienation from embodied existence.

Like Aristotle, Thomas Aquinas holds that the rational soul is the substantial form of the human body. In so doing, he takes himself to be rejecting a Platonic version of substance dualism; his criticisms, however, apply equally to a traditional understanding of Cartesian dualism. Aquinas’s own peculiar brand of dualism is receiving increased attention from contemporary philosophers—especially those attracted to positions that fall between Cartesian substance dualism and reductive materialism. What Aquinas’s own view amounts to, however, is subject to debate. (...) Philosophers (such as J. P. Moreland and Scott Rae) have claimed that ‘Thomistic substance dualism’ (TSD) centers around two beliefs: (1) the rational soul is an immaterial substance, and (2) this immaterial substance is the human person. In this paper, I argue that labeling such an account ‘Thomistic’ proves dangerously misleading—not only does Aquinas himself explicitly deny both of these claims, but he denies them for philosophically significant reasons. Furthermore, I argue that Aquinas’s own position provides an account of human nature both more coherent and philosophically attractive. (shrink)

This text explores a set of key concepts in Marxist theory as developed and read by Lacan, demonstrating links and connections between Marxist thought and Lacanian practice. The book examines the complexity of these encounters through the structure of a comprehensive vocabulary which covers diverse areas, from capitalism and communism to history, ideology, politics, work, and family. Offering new perspectives on these concepts in psychoanalysis, as well as in the fields of political and critical theory, the book brings together contributions (...) from a range of international experts to demonstrate the dynamic relationship between Marx and Lacan, as well as illuminating 'untranslatable points' which may offer productive tension between the two. The entries trace the trajectory of Lacan's appropriation of Marx's concepts and analyses how they were questioned, criticized and reworked by Lacan, accounting for the wide reach of two thinkers and worlds in constant homology. Each entry also discusses psychoanalytic debates relating to the concept and seeks to refine the clinical scope of Marx's work, demonstrating its impact on the social and individual dimensions of Lacanian clinical practice. With a practical and structured approach, The Marx Through Lacan Vocabulary will appeal to psychoanalysts and researchers in a range of fields, including political science, cultural studies, and philosophy.

A growing number of children in the United States are exposed to multiple languages at home from birth. However, relatively little is known about the early process of word learning—how words are mapped to the referent in their child-centered learning experiences. The present study defined parental input operationally as the integrated and multimodal learning experiences as an infant engages with his/her parent in an interactive play session with objects. By using a head-mounted eye tracking device, we recorded visual scenes from (...) the infant’s point of view, along with the parent’s social input with respect to gaze, labeling, and actions of object handling. Fifty-one infants and toddlers from an English monolingual or a diverse bilingual household were recruited to observe the early multimodal learning experiences in an object play session. Despite that monolingual parents spoke more and labeled more frequently relative to bilingual parents, infants from both language groups benefit from a comparable amount of socially coordinated experiences where parents name the object while the object is looked at by the infant. Also, a sequential path analysis reveals multiple social coordinated pathways that facilitate infant object looking. Specifically, young children’s attention to the referent objects is directly influenced by parent’s object handling. These findings point to the new approach to early language input and how multimodal learning experiences are coordinated socially for young children growing up with monolingual and bilingual learning contexts.

Although elementary schools are considered a fertile ground for promoting positive behaviors among students, to date, almost no study has examined the effectiveness of a cyberbullying prevention program among elementary school students of typical and non-typical development. The present study evaluated the effectiveness of such a school-based European funded preventive program among sixth graders with and without special educational needs. The study also examined the predictive role of self-esteem in students’ cyberbullying involvement. Overall, 240 students from randomly selected Greek schools (...) completed a self-report questionnaire, which included a scale on cyberbullying and self-esteem. Following an experimental longitudinal research design, the intervention was applied to the experimental but not to the control group of students. Each group consisted of both students with and without SEN. The evaluation was based on the completion of the self-report questionnaire before, immediately after, and 6 months after the intervention was completed by trained general and special education teachers. According to the findings, students’ cyberbullying engagement decreased significantly in the second and third phase, and especially for those with SEN. Additionally, self-esteem negatively predicted students’ involvement in cyberbullying in all three phases. The findings partially support the appropriateness of interventions within the elementary school context in order to enhance self-esteem and promote a safe online culture among students of typical as well as atypical development.

The fast-developing field of neuroscience has given philosophy, as well as other disciplines and the public broadly, many new tools and perspectives for investigating one of our most pressing challenges: addressing the health and well-being of our mental lives. In some cases, neuroscientific innovation has led to clearer understanding of the mechanisms of mental illness and precise new modes of treatment. In other cases, features of neuroscience itself, such as the enticing nature of the data it produces compared to previous (...) behavioral methods, together with its costliness and “coldness” have complicated understanding of mental illness and decision making about mental illness. Taking neuroscientific information into account can leave practitioners in psychiatry and law with difficult questions, stemming not only from the complexity of these fields, but also from our rapidly evolving understanding of and facility with neuroscience. In this chapter, we will review several examples of the insights and dilemmas that have unfolded as mental illness has been examined through the lens of neuroscience, covering diagnoses such as obsessive-compulsive disorder (OCD), schizophrenia, addiction, and severe mood disorders.

A set of constraints forces trade-offs which prevent us from achieving the best possible definitions of the ‘level’ and ‘unit’ of natural selection. This set consists in decisions concerning conflicting pre-analytic intuitions in problematic cases, the relative roles of various conceptual resources in the definitions, which facts need to be accounted for using the definitions, how the relation between selection and evolution orients the definitions, and the relation between the level and unit concepts. Systematic reconstruction and evaluation of leading analyses (...) along these dimensions favors a new functional analysis over Williams’ consequentialist analysis, Sober’s causal analysis, and Dawkins’ teleological analysis.

This book examines sociobiology’s validity and significance, using the sociobiological theory of the evolution of mating and parenting as an example. It identifies and discusses the array of factors that determine sociobiology’s effort to become a science, providing a rare, balanced account—more critical than that of its advocates and more constructive than that of its critics. It sees a role for sociobiology in changing the way we understand the goals of evolutionary biology, the proper way to evaluate emerging sciences, and (...) the deep structure of scientific theories. The book’s premise is that evolutionary biology would not be complete if it did not explain evolutionarily significant social facts about nonhumans and humans. It proposes that explanations should be evaluated in terms of their basis in underlying theories, research programs, and conceptual frameworks. (shrink)
