Perception of music and speech is based on similar auditory skills, and it is often suggested that those with enhanced music perception skills may perceive and learn novel words more easily. The current study tested whether music perception abilities are associated with novel word learning in an ambiguous learning scenario. Using a cross-situational word learning (CSWL) task, nonmusician adults were exposed to word-object pairings between eight novel words and visual referents. Novel words were either non-minimal pairs differing in all sounds (...) or minimal pairs differing in their initial consonant or vowel. In order to be successful in this task, learners need to be able to correctly encode the phonological details of the novel words and have sufficient auditory working memory to remember the correct word-object pairings. Using the Mistuning Perception Test (MPT) and the Melodic Discrimination Test (MDT), we measured learners’ pitch perception and auditory working memory. We predicted that those with higher MPT and MDT values would perform better in the CSWL task and in particular for novel words with high phonological overlap (i.e., minimal pairs). We found that higher musical perception skills led to higher accuracy for non-minimal pairs and minimal pairs differing in their initial consonant. Interestingly, this was not the case for vowel minimal pairs. We discuss the results in relation to theories of second language word learning such as the Second Language Perception model (L2LP).

DNA replication is both highly conserved and controlled. Problematic DNA replication can lead to genomic instability and therefore carcinogenesis. Numerous mechanisms work together to achieve this tight control and increasing evidence suggests that post‐translational modifications (phosphorylation, ubiquitination, SUMOylation) of DNA replication proteins play a pivotal role in this process. Here we discuss such modifications in the light of a recent article that describes a novel role for the deubiquitinase (DUB) USP7/HAUSP in the control of DNA replication. USP7 achieves this function (...) by an unusual and novel mechanism, namely deubiquitination of SUMOylated proteins at the replication fork, making USP7 also a SUMO DUB (SDUB). This work extends previous observations of increased levels of SUMO and low levels of ubiquitin at the on‐going replication fork. Here, we discuss this novel study, its contribution to the DNA replication and genomic stability field and what questions arise from this work. (shrink)

In this paper we describe a test for Nijhout's hypothesis that the eyespot patterns on butterfly wings are the result of a threshold reaction of the epidermal cells to a concentration gradient of a diffusing degradable morphogen produced by focal cells at the centre of the future eyespot. The wings of the nymphalid butterfly, Bicyclus anynana, have a series of eyespots, each composed of a white pupil, a black disc and a gold outer ring. In earlier extirpation and transplantation experiments (...) it has been established that these eyespots are indeed organised around groups of signalling cells active during the first hours of pupal development. If these cells were to supply the positional information for eyespot formation in accordance with Nijhout's diffusion-degradation gradient model, then, when two foci are close together, the signals should sum, and this effect should be apparent in the detailed shape of the resulting pigment pattern. We give an equation for the form of the contours that would be obtained in this manner. We use this to test the morphogen gradient hypothesis on measurements of the outlines of fused eyespots obtained either by grafting focal cells close together, or by using a mutation that produces adjacent fused eyespots. The contours of the fused patterns were found to satisfy our equation, thus corroborating Nijhout's hypothesis to the extent possible with this particular type of experiment. (shrink)

We performed an EEG graph analysis on data from 31 typical readers and 24 dyslexics, recorded while they were engaged in an audiovisual task and during resting-state. The task simulates reading acquisition as participants learned new letter-sound mappings via feedback. EEG data was filtered for the delta, theta, alpha, and beta bands. We computed the Phase Lag Index to provide an estimate of the functional connectivity between all pairs of electrodes per band. Then, networks were constructed using a Minimum Spanning (...) Tree, a unique sub-graph connecting all nodes without loops, aimed at minimizing bias in between groups and conditions comparisons. Both groups showed a comparable accuracy increase during task blocks, indicating that they correctly learned the new associations. The EEG results revealed lower task-specific theta connectivity, and lower theta degree correlation over both rest and task recordings, indicating less network integration in dyslexics compared to typical readers. This pattern suggests a role of theta oscillations in dyslexia and may reflect differences in task engagement between the groups, although robust correlations between MST metrics and performance indices were lacking.

If someone commits the mereological fallacy, then he ascribes psychological predicates to parts of an animal that apply only to the (behaving) animal as a whole. This incoherence is not strictly speaking a fallacy, i.e. an invalid argument, since it is not an argument but an illicit predication. However, it leads to invalid inferences and arguments, and so can loosely be called a fallacy. However, discussions of this particular illicit predication, the mereological fallacy, show that it is often misunderstood. Many (...) misunderstandings concern the use of this illicit predication in the course of discussions of understanding the mind/body problem. Our aim here is to provide an accessible overview through discussing common misconceptions of the fallacy. We also discuss how conceptual investigations of the relation between living organisms and their parts fit within the framework of modern evolutionary theory, i.e. inclusive fitness theory. (shrink)

In our earlier work, we argued, contra Searle, that institutional facts can be understood in terms of non-institutional facts about actions and incentives. Butchard and D’Amico claim that we have misinterpreted Searle, that our main argument against him has no merit and that our positive view cannot account for institutional facts created via joint action. We deny all three charges.

This book seeks to explain why different systems of sovereign states have built different types of fundamental institutions to govern interstate relations. Why, for example, did the ancient Greeks operate a successful system of third-party arbitration, while international society today rests on a combination of international law and multilateral diplomacy? Why did the city-states of Renaissance Italy develop a system of oratorical diplomacy, while the states of absolutist Europe relied on naturalist international law and "old diplomacy"? Conventional explanations of basic (...) institutional practices have difficulty accounting for such variation. Christian Reus-Smit addresses this problem by presenting an alternative, "constructivist" theory of international institutional development, one that emphasizes the relationship between the social identity of the state and the nature and origin of basic institutional practices. Reus-Smit argues that international societies are shaped by deep constitutional structures that are based on prevailing beliefs about the moral purpose of the state, the organizing principle of sovereignty, and the norm of procedural justice. These structures inform the imaginations of institutional architects as they develop and adjust institutional arrangements between states. As he shows with detailed reference to ancient Greece, Renaissance Italy, absolutist Europe, and the modern world, different cultural and historical contexts lead to profoundly different constitutional structures and institutional practices. The first major study of its kind, this book is a significant addition to our theoretical and empirical understanding of international relations, past and present. (shrink)

The distinction between concept and intuition is of the utmost importance for understanding Kant’s critical philosophy. For, as Kant himself claimed, all the distinctive claims of this philosophy rest on, and develop out of, a detailed account of the way all our cognition of things requires both intuitions and concepts.

Contemporary discussion concerning institutions focus on, and mostly accept, the Searlean view that institutional objects, i.e. money, borders and the like, exist in virtue of the fact that we collectively represent them as existing. A dissenting note has been sounded by Smit et al. (Econ Philos 27:1–22, 2011), who proposed the incentivized action view of institutional objects. On the incentivized action view, understanding a specific institution is a matter of understanding the specific actions that are associated with the institution (...) and how we are incentivized to perform these actions. In this paper we develop the incentivized action view by extending it to institutions like property, promises and complex financial organisations like companies. We also highlight exactly how the incentivized action view differs from the Searlean view, discuss the method appropriate to such study and discuss some of the virtues of the incentivized action view.

Darwin’s theory predicts that linguistic behavior gradually evolved out of animal forms of communication. However, this prediction is confronted by the conceptual problem that there is an essential difference between signaling and linguistic behavior: using words is a normative practice. It is argued that we can resolve this problem if we note that language evolution is the outcome of an evolutionary transition, and observe that the use of words evolves during ontogenesis out of babbling. It is discussed that language evolved (...) as the result of an expansion of the vocalizing powers of our ancestors. This involved an increase in the volitional control of our speech apparatus, but also the evolution of socially guided learning. It resulted in unique human abilities, namely doing things with words and later reasoning and giving reasons. (shrink)

This paper argues that the substance concept, as discussed by Aristotle in his Categories, aids us to improve our understanding of human nature. Aristotle distinguished the primary from the secondary substance, and substantial from accidental change. We explain these distinctions, their use for understanding phenomena, and discuss how we can integrate them with evolutionary explanations of human nature. For explaining of how the typical human characteristics evolved, we extend our investigations with a discussion of the concept of person. It is (...) argued that psychological attributes, used to characterize persons, are not attributes of a separate mental substance, as Cartesians believe. The concept of a person, though not a substance concept, qualifies a substance concept of a human being possessing rational powers. The latter evolved as the result of language evolution. (shrink)

There is a simple, intuitive theory of the semantic reference of proper names that has been unjustly neglected. This is the view that semantic reference is conventionalized speakers reference, i.e. the view that a name semantically refers to an object if, and only if, there exists a convention to use the name to speaker-refer to that object. The theory can be found in works dealing primarily with other issues (e.g. Stine in Philos Stud 33:319–337, 1977; Schiffer in Erkenntnis 13:171–206, 1978; (...) Sainsbury in Erkenntnis 80:195–214, 2015; Sainsbury, Thinking about things, Oxford University Press, 2018), yet these authors provide no sustained discussion of it. Devitt (Designation, Columbia University Press, 1981) did formulate a view on which semantic reference is conventionalized speaker’s reference, yet his views are assimilated to causalist views. This is a mistake. While the conventionalized speaker’s reference view captures much of what is plausible in descriptivism and causalism, it remains distinct from both. (shrink)

Joseph Almog pointed out that Kripkean causal chains not only exist for names, but for all linguistic items (Almog 1984: 482). Based on this, he argues that the role of such chains is the presemantic one of assigning a linguistic meaning to the use of a name (1984: 484). This view is consistent with any number of theories about what such a linguistic meaning could be, and hence with very different views about the semantic reference of names. He concludes that (...) the causal theory is ‘rather trivial’ (1984: 487). In this paper I argue that Almog is correct to hold that the causal theory is trivial, but, contra Almog, argue that the triviality of the existence of causal chains is not a matter of such chains having a presemantic role in assigning linguistic meanings to utterances. Instead, such triviality is due to the fact that the causal theory reflects no more than a truism about the epistemology of convention acquisition. (shrink)

Williams argued that Darwin replaced teleology by natural selection. This article argues that this idea is based on a misunderstanding of Darwin’s critique of the argument from design. Darwin did not replace teleology by evolutionary explanations but showed that we can understand teleology without referring to a Designer. He eliminated the concept of design and rehabilitated Aristotelian teleological explanations. The implication is that adaptations should not be investigated as if designed, but with the help of both teleological and evolutionary explanations. (...) It is argued that elaborations of teleological explanations enable us to reconcile evolutionary theory and other fields in science. (shrink)

Declarations like “this meeting is adjourned” make certain facts the case by representing them as being the case. Yet surprisingly little attention has been paid to the mechanism whereby the utterance of a declaration can bring about a new state of affairs. In this paper, we use the incentivization account of institutional facts to address this issue. We argue that declarations can serve to bring about new states of affairs as their utterance have game theoretical import, typically in virtue of (...) the utterer signaling a commitment to act in an incentive-changing way.

Nos últimos anos, muito foi escrito a respeito das virtudes e das virtudes particulares expostas na ética de Kant, concentrando-se em particular no Tugendlehre, parte II da Metafísica da Moral. Menos atenção foi dada ao que Kant tem a dizer sobre os vícios e sobre os vícios particulares. A própria discussão de Kant a respeito dos vícios escolhidos no Tugendlehre é bastante breve, pontuada por observações a respeito das fontes psicológicas de traços de caráter viciosos. Em contraste, o que encontramos (...) em algumas das anotações de aula, é uma discussão consideravelmente rica sobre a psicologia de outros vícios relacionados envolvendo aquilo a que Kant se refere como emulação – um “impulso” implantado na natureza humana que inclina fortemente os homens a serem “iguais aos outros em cada aspecto”. Embora este impulso implantado tenha o bem do auto-melhoramento como seu propósito, sob algumas circunstâncias ele contribui para os vícios diabólicos da inveja, da ingratidão e da Schadenfreude. Nosso objetivo básico aqui é fornecer uma interpretação das ideias de Kant a respeito da psicologia dos vícios diabólicos – como indivíduos sucumbem a estes vícios – baseados em observações das Lectures. É de particular interesse em que medida estes vícios compartilham de uma unidade psicológica subjacente, uma afirmação sugerida por algumas das observações de Kant. (shrink)

In The Construction of Social Reality, John Searle develops a theory of institutional facts and objects, of which money, borders and property are presented as prime examples. These objects are the result of us collectively intending certain natural objects to have a certain status, i.e. to ‘count as’ being certain social objects. This view renders such objects irreducible to natural objects. In this paper we propose a radically different approach that is more compatible with standard economic theory. We claim that (...) such institutional objects can be fully understood in terms of actions and incentives, and hence the Searlean apparatus solves a non-existent problem. (shrink)

We describe and analyse how large herbivores strongly diminished a woody vegetation, dominated by the unpalatable shrub Sambucus nigra L. and changed it into grassland. Density of woody species and cover of vegetation were measured in 1996, 2002 and 2012 in the grazed Oostvaardersplassen. In 2002 and 2012 we also measured density and cover in an ungrazed control site. In 2002 we measured intensity of browsing and bark loss of Sambucus shrubs in the grazed and control sites. In the grazed (...) site the density of Sambucus and Salix spp. declined significantly between 1996 and 2012, and large areas changed into grassland. In the control site the density of Sambucus increased significantly during this period, the density of Salix spp. did not change, and the vegetation consisted of a mixture of woody species and a field layer dominated by tall herbs. In 2002 and 2012 the percentages of dead Sambucus shrubs were significantly higher in the grazed site than in the control site. In 2002 the percentages of twigs browsed and ring barked stems of Sambucus shrubs were significantly higher in the grazed site than in the control site. Our results show that debarking caused mature Sambucus shrubs to die, but that heavy browsing may have helped this process. Our results also point to a significant neighbour effect on the break down of Sambucus, suggesting that Aggregational Resistance and Associational Palatability were both active. Essential conditions for the break down of this woody vegetation were the presence of large herbivores, the low ratio between the areas of summer and winter feeding habitats and the competition amongst herbivores. Browsing may have been responsible for seedling death, as seedlings were found only in the control site and not on the old and newly established grasslands in the grazed site. (shrink)

Badcock and Crespi have advanced the hypothesis that autism and schizophrenia are caused by imbalanced imprinting in the brain. They argue that an imbalance between the effects of paternally and maternally expressed genes on brain development results in either an extreme paternal (autism) or maternal brain (schizophrenia). In this paper their conceptual model is discussed and criticized since it presupposes an incoherent distinction between observable physical and hidden mental phenomena. An alternative model is discussed that may be more fruitful for (...) investigating the possible role of imprinted genes in the development of social behaviour. The development of crying and reactive crying and behaviours necessary for collaborative action are discussed as a promising research area for understanding the effects of imprinted genes. (shrink)

Comte argued against the Cartesian conception of the mind that the thinker cannot simultaneously think or perceive and observe itself so doing. Based on insights from cognitive neuroscience, Dehaene has recently given a contemporary answer to Comte’s challenge. He has extended some ideas of Helmholtz on unconscious inferences and argued that we can resolve Comte’s problem by reformulating it in terms of the brain. Since the brain consists of different parts having different functions, it is possible that some parts are (...) involved in observing (they unconsciously process information) while other parts integrate the received information resulting in conscious experiences to which we have access. Dehaene’s answer is criticized and the alternative neo-Aristotelian resolution of Comte’s challenge is discussed. Explanations of blindsight are used to illustrate the differences between the two responses to Comte’s challenge. (shrink)

There are two prevailing interpretations of the status which Kant accorded his claims in the Critique of Pure Reason: 1) he is analyzing our concepts of cognition and experience; 2) he is making empirical claims about our cognitive faculties. I argue for a third alternative: on Kant's account, all cognition consists in a reflective consciousness of our cognitive faculties, and in critique we analyze the content of this consciousness. Since Strawson raises a famous charge of incoherence against such a position, (...) I begin by showing that this charge is misplaced. (shrink)

We live today in the first global system of sovereign states in history, encompassing all of the world's polities, peoples, religions and civilizations. Christian Reus-Smit presents a new account of how this system came to be, one in which struggles for individual rights play a central role. The international system expanded from its original European core in five great waves, each involving the fragmentation of one or more empires into a host of successor sovereign states. In the most important, (...) associated with the Westphalian settlement, the independence of Latin America, and post-1945 decolonization, the mobilization of new ideas about individual rights challenged imperial legitimacy, and when empires failed to recognize these new rights, subject peoples sought sovereign independence. Combining theoretical innovation with detailed historical case studies, this book advances a new understanding of human rights and world politics, with individual rights deeply implicated in the making of the global sovereign order.

Russell claims that ordinary proper names are eccentric, i.e. that the semantic referent of a name is determined by the descriptive condition that the individual utterer of the name associates with the name. This is deeply puzzling, for the evidence that names are subject to interpersonal coordination seems irrefutable. One way of making sense of Russell’s view would be to claim that he has been systematically misinterpreted and did not, in fact, offer a semantic theory at all. Such a view (...) is put forward in Sainsbury Departing from Frege, Routledge, London, 2002). Sainsbury claims that Russellian descriptivism is not the theory that the thought in the mind of the speaker determines the semantic reference of a name, but simply a theory about the thought in the mind of the speaker using a name. I argue that the truth is subtly different, and points the way towards an intuitive explanation of Russell’s eccentricity. (shrink)

Contemporary theories of institutions as clusters of stable solutions to recurrent coordination problems can illuminate and explain some unresolved difficulties and problems adhering to institutional definitions of art initiated by George Dickie and Arthur Danto. Their account of what confers upon objects their institutional character does not fit well with current work on institutions and social ontology. The claim that “the artworld” confers the status of “art” onto objects remains utterly mysterious. The “artworld” is a generic notion that designates a (...) sphere of human activity that involves practices that create goals that have led to the emergence of formal and informal institutions. But those institutions, rather than magically “creating” objects subjected to esthetic appreciation, merely solve familiar and ubiquitous coordination problems created by artistic activity in ways other institutions in other areas solve similar and/or analogous coordination problems.

Most analyses of whistleblowing are concerned with the whistleblower as an actor or with the act of whistleblowing itself. However, as soon as the whistleblower enters the public arena, a social dynamic emerges of interdependent actors with different responsibilities and different interests.Such a dynamic demands a more comprehensive approach in which the motives of the different actors in the public debate are taken into account.This approach is developed here using an exemplary case of whistleblowing that took place in a Dutch (...) research institute.The intensive media attention damaged both the institute and the whistleblower.In retrospect this could have been avoided.In our analysis we give extra attention to the motives involved and to the inevitability of media logic.In order to avoid unnecessary damage we recommend guidelines to the three basic actors:the whistleblower, the organization and the media.

The kinship theory of genomic imprinting predicts that imprinted genes affect parent–child and child–child interactions. During prenatal and neonatal stages, patrigenes promote selfish and matrigenes altruistic behavior. Models predict that this imprinted gene expression pattern is reversed starting with the juvenile stage. This article explores possible effects of imprinted genes on nonverbal and simple and complex linguistic behaviors before and after the reversal. A hypothesis is discussed that is based on the observation language evolved as a new form of communicative (...) behavior. Inclusive fitness theory is used for explaining how and why new forms of communicative behaviors evolved as an extension of behaviors and gestures displayed by our predecessors. The hypothesis is elaborated through discussing a scenario of early language evolution. This scenario is used for explaining early stages in child development and for discussing possible effects of patrigenes and matrigenes on the development of children’s communicative behaviors.

Human enhancement issues are not merely academic: the technologies and trends involved give rise to new needs and social demands, provide opportunities for individuals and society, and present new risks. They also challenge crucial cultural notions, social concepts and views of the human condition, and may cause new forms of social pressure and social exclusion. This chapter reports on a systematic attempt by the European Technology Assessment Group (ETAG), conducted on behalf of the Science and Technology Options Assessment (STOA) panel (...) of the European Parliament, to suggest policy options on the issue of human enhancement. It outlines and discusses a number of strategies for dealing with the issue in a European policy context, identifying a reasoned pro‐enhancement approach, a reasoned restrictive approach, and a systematic case‐by‐case approach as viable options.

Background Genuine uncertainty on superiority of one intervention over the other is called equipoise. Physician-investigators in randomized controlled trials need equipoise at least in studies with more than minimal risks. Ideally, this equipoise is also present in patient-participants. In pediatrics, data on equipoise are lacking. We hypothesize that 1) lack of equipoise at enrolment among parents may reduce recruitment; 2) lack of equipoise during participation may reduce retention in patients assigned to a less favoured treatment-strategy. Methods We compared preferences of (...) parents/patients at enrolment, documented by a questionnaire, with preferences developed during follow-up by an interview-study to investigate equipoise of child-participants and parents in the BeSt-for-Kids-study. This trial in new-onset Juvenile Idiopathic Arthritis-patients consists of three strategies. One strategy comprises initial treatment with a biological disease-modifying-antirheumatic-drug, currently not standard-of-care. Semi-structured interviews were conducted with 23 parents and 7 patients, median 11 months after enrolment. Results Initially most parents and children were not in equipoise. Parents/patients who refused participation, regularly declined due to specific preferences. Many participating families preferred the biological-first-strategy. They participated to have a chance for this initial treatment, and would even consider stopping trial-participation when not randomized for it. Their conviction of superiority of the biological-first strategy was based on knowledge from internet and close relations. According to four parents, the physician-investigator preferred the biological-first-strategy, but the majority stated that she had no preferred strategy. In phase 2, preferences tended to change to the treatment actually received. Conclusions Lack of equipoise during enrolment did not reduce study recruitment, mainly due to the fact that preferred treatment was only available within the study. Still, when developing a trial it is important to evaluate whether the physicians’ research question is in line with preferences of the patient-group. By exploring so-called ‘informed patient-group’-equipoise, successful recruitment may be enhanced and bias avoided. In our study, lack of equipoise during trial-participation did not reduce retention in those assigned to a less favoured option. We observed a change for preference towards treatment actually received, possibly explained by comparable outcomes in all three arms. (shrink)

AimThe neurocognitive basis of Developmental Coordination Disorder remains an issue of continued debate. This combined systematic review and meta-analysis provides a synthesis of recent experimental studies on the motor control, cognitive, and neural underpinnings of DCD.MethodsThe review included all published work conducted since September 2016 and up to April 2021. One-hundred papers with a DCD-Control comparison were included, with 1,374 effect sizes entered into a multi-level meta-analysis.ResultsThe most profound deficits were shown in: voluntary gaze control during movement; cognitive-motor integration; practice-/context-dependent (...) motor learning; internal modeling; more variable movement kinematics/kinetics; larger safety margins when locomoting, and atypical neural structure and function across sensori-motor and prefrontal regions.InterpretationTaken together, these results on DCD suggest fundamental deficits in visual-motor mapping and cognitive-motor integration, and abnormal maturation of motor networks, but also areas of pragmatic compensation for motor control deficits. Implications for current theory, future research, and evidence-based practice are discussed.Systematic Review RegistrationPROSPERO, identifier: CRD42020185444. (shrink)

Osteons are cylindrical structures of bone created by matrix resorbing osteoclasts, followed by osteoblasts that deposit new bone. Osteons align with the principal loading direction and it is thought that the osteoclasts are directed by osteocytes, the mechanosensitive cells that reside inside the bone matrix. These osteocytes are presumably controlled by interstitial fluid flow, induced by the physiological loading of bones. Here I consider the stimulation of osteocytes while the osteon is closed by osteoblasts. In a conceptual finite element model, (...) bone is considered a poro‐elastic material and subjected to locomotion‐induced loading conditions. It appears that the magnitude of flow is constant along the closing cone, while shear strain rate in the bone matrix diminishes linearly with the deposition of bone. This suggests that shear strain rate, rather than fluid flow, is the physical cue that controls osteocytes and bone deposition in newly formed osteons. (shrink)

Abusive practices in elite women’s artistic gymnastics have been the focus of discussions about how to eliminate or reduce them. Both coaches and parents have been named as key actors in bringing about change. Our focus is on parents and their ability to safeguard their daughters in WAG. Parents are not independent actors, however, but are part of a larger web consisting of an entanglement of emotions and technologies and rationalities used by staff, other parents, and athletes, bounded by skill (...) development plans and by coaching expertise and authority. This entanglement may limit the ability of parents to bring about change. We draw on a Deleuzian notion of assemblage, Foucauldian concepts of discourse and governmentality and Ahmed’s assertion about the entanglement of discourses and emotions to explore how parents are disciplined into accepting dominant discursive practices of sport clubs for elite athletes. The data were drawn from a project called the Parental Awareness Program that was designed to make parents aware of practices in competitive WAG that may not be in their child’s best interest. Participants were parents of young gymnasts who had been identified as “talented” and who were members of an elite gymnastics club. The data analysis was based on focus group discussions with a total of 22 parents and semi-structured interviews with 8 parents. The results suggested that although parents problematized many practices during PAP, processes of governmentality involving an assemblage of discourses about coaching expertise, families, talent, enjoyment, long term skill development plans and its associated time demands, together ensured parental consent for dominant practices. The data suggested that a reduction of abusive practices lies in part in critical examinations of skill development plans that are presented as regimes of truth and are kept in place by emotions and the authority accorded to coaching expertise. These processes curtail parents in their ability to safeguard what is in the best pedagogical interest of their daughter. (shrink)

Can the law benefit from an evolutionary perspective? This little book shows how the idea of survival of the fittest can help explain legal development and the rise and fall of legal institutions. The reader is invited to join in on a journey of discovery in which the world of Darwin is connected to the topics of legal change, convergence of law, legal complexity, law in hip-hop music and the adoption of the price-payment rule. Exploring these five themes from an (...) evolutionary angle indisputably upsets our traditional view of the law, but it does fit the author's view of academia as a place for cross-disciplinary research steered by curiosity.

We tested if the newly designed ToMotion task reflects a single construct and if the atypical groups differ in their performance compared to typically developing peers. Furthermore, we were interested if ToMotion maps a developmental sequence in a Theory of Mind performance as exemplified by increasing difficulty of the questions asked in every item. The sample consisted of 13 adolescents that have been diagnosed with a developmental language disorder and 14 adolescents that are deaf or hard of hearing. All of (...) these adolescents were in special schools for secondary vocational education. The control group existed of 34 typical developing adolescents who were in regular intermediate vocational education, ranging from level 2 to 4. The ToMotion, available in a spoken Dutch version and in a version in Sign Language of the Netherlands, was used to map ToM abilities. An attempt has been made to fill the gap of missing studies of ToM in adolescents by developing a new measuring instrument. In conclusion, assessing ToM with the ToMotion results in a picture that DHH adolescents score lower than TD peers. However, their scores are as consistent as those of the TD peers. The picture of DLD adolescents is the reverse. They show no differences in ToM scores, but seem to be somewhat more inconsistent compared to TD peers. We provide a discussion on those results and its implications for future research. What this paper adds? The current study introduces a new visual Theory of Mind task, ToMotion, designed specifically to assess ToM in adolescents in an ecologically valid way and adapted to the needs of adolescents with language and communication difficulties.
