Keeping a conversation going is the social glue of friendships. The DSM criteria for autism list difficulties with back-and-forth conversation but does not necessitate that all autistic children will be equally impacted. We carried out three studies (two pre-registered) with verbally-fluent school children (age 5-9 years) to investigate how autistic and neurotypical children maintain a conversation topic. We also investigated within-group relationships between conversational ability and cognitive and socio-cognitive predictors. Study 1 found autistic children were more likely than neurotypical controls (...) to give off-topic and generic minimal responses (e.g. ‘mm’, ‘oh’) and were less likely to give non-verbal responses (e.g. nodding or use of facial affect to respond). Nonetheless, the autistic group provided topic-supporting responses 62% of the time, indicating some aspects of conversation topic maintenance are a relative strength. Studies 2 and 3 found large individual differences in topic-supporting conversational responding amongst both neurotypical and autistic children. These were positively related to theory of mind ability and age in both groups. Conversational skills lie on a continuum for the general population and differences by diagnostic group are a matter of degree. Given the importance for peer relationships, we suggest a whole-classroom approach to supporting conversation skills in all children. (shrink)

This article suggests evidence for and reasons why prior acquisition may either facilitate or inhibit acquisition of a new construction. It investigates acquisition of the German passive and future constructions which contain a lexical verb with either the auxiliary sein “to be” or werden “to become”, and are related through these to potential supporting constructions. We predicted that a supported construction should be acquired earlier, faster, and unusually rapidly. An inhibited construction should show an extended depressed usage. We analyzed a (...) dense corpus of a German boy between 2;0 and 5;0. He acquired the sein- before the werden-passive. The former was supported by his prior acquisition of the sein copula, whereas the werden-passive itself supported one werden copula construction. He acquired the werden-future extremely slowly due to the hindrance of a semantically identical construction. These results fit with an emergentist approach in which apparently “sudden” acquisition is still due to gradual learning mechanisms. (shrink)

Background: Studies have found that children with Autism Spectrum Disorder (ASD) are more likely to make errors in appropriately producing referring expressions (‘the dog’ vs. ‘the black dog’) than are controls but comprehend them with equal facility. We tested whether this anomaly arises because comprehension studies have focused on manipulating perspective-taking at a ‘generic speaker’ level. Method: We compared 24 autistic eight- to eleven-year-olds with 24 well-matched neuro-typical controls. Children interpreted requests (e.g. ‘Can I have that ball?’) in contexts which (...) would be ambiguous (i.e. because the child can see two balls) if perspective-taking were not utilized. In the interlocutor-specific perspective-taking condition, the target was the particular object which was new for the speaker. Children needed to take into account what the speaker had played with before and the fact that they were now expressing excitement about something new. In two control ‘speaker-generic’ conditions we tested children’s ability to take the visual perspective of the speaker (where any speaker who stood behind a particular barrier would have the same perspective). Results: The autistic group were significantly less likely to select the target and significantly more likely to request clarification in the ‘interlocutor-specific’ condition. Performance in the ‘interlocutor-generic’ (visual) perspective taking conditions did not differ between groups. Conclusion: Autistic children, even those who are not intellectually-impaired, tend to have more difficulty than neuro-typical peers in comprehending referring expressions when this requires understanding that people comment on what is new for them.

Many studies show a developmental advantage for transitive sentences with familiar verbs over those with novel verbs. It might be that once familiar verbs become entrenched in particular constructions, they would be more difficult to understand (than would novel verbs) in non-prototypical constructions. We provide support for this hypothesis investigating German children using a forced-choice pointing paradigm with reversed agent-patient roles. We tested active transitive verbs in study 1. The 2-year olds were better with familiar than novel verbs, while the (...) 2½-year olds pointed correctly for both. In study 2, we tested passives: 2½-year olds were significantly below chance for familiar verbs and at chance for novel verbs, supporting the hypothesis that the entrenchment of the familiar verbs in the active transitive voice was interfering with interpreting them in the passive voice construction. The 3½-year olds were also at chance for novel verbs but above chance with familiar verbs. We interpret this as reflecting a lessening of the verb-in-construction entrenchment as the child develops knowledge that particular verbs can occur in a range of constructions. The 4½-year olds were above chance for both familiar and novel verbs. We discuss our findings in terms of the relative entrenchment of lexical and syntactic information and to interference between them. (shrink)

One feature of autism spectrum disorder (ASD) is a deficit in verbal reference production; i.e., providing an appropriate amount of verbal information for the listener to refer to things, people, and events. However, very few studies have manipulated whether individuals with ASD can take a speaker’s perspective in order to interpret verbal reference. A critical limitation of all interpretation studies is that comprehension of another’s verbal reference required the participant to represent only the other’s visual perspective. Yet, many everyday interpretations (...) of verbal reference require knowledge of social perspective (i.e., a consideration of which experiences one has shared with which interlocutor). We investigated whether 22 5;0- to 7;11-year-old children with ASD and 22 well-matched typically developing (TD) children used social perspective to comprehend (Study 1) and produce (Study 2) verbal reference. Social perspective-taking was manipulated by having children collaboratively complete activities with one of two interlocutors such that for a given activity, one interlocutor was Knowledgeable and one was Naïve. Study 1 found no between-group differences for the interpretation of ambiguous references based on social perspective. In Study 2, when producing referring terms, the ASD group made modifications based on listener needs, but this effect was significantly stronger in the TD group. Overall, the findings suggest that high-functioning children with ASD know with which interlocutor they have previously shared a given experience and can take this information into account to steer verbal reference. Nonetheless, they show clear performance limitations in this regard relative to well-matched controls. (shrink)

The constructionist approach argues that communication is central to language learning, language use, and language change. We argue that the approach provides a useful perspective on how autistic children learn language, as it anticipates variable outcomes and suggests testable predictions. First, a reduced ability and interest in tracking the attention and intentions of others should negatively impact early language development, and a wealth of evidence indicates that it does. Secondly, and less discussed until recently, a hyper-focus on specifics at the (...) expense of generalizations, common among people on the spectrum, should also negatively impact language development, and recent evidence suggests this is also the case. Pace Kissine (this volume), it is unsurprising that children can learn some second language from watching videos, and it is unclear how an appeal to “innate” language-specific knowledge could explain the range of outcomes of individuals on the autism spectrum.

This study investigates the child‐directed speech (CDS) of four Russian‐, six German, and six English‐speaking mothers to their 2‐year‐old children. Typologically Russian has considerably less restricted word order than either German or English, with German showing more word‐order variants than English. This could lead to the prediction that the lexical restrictiveness previously found in the initial strings of English CDS by Cameron‐Faulkner, Lieven, and Tomasello (2003) would not be found in Russian or German CDS. However, despite differences between the three (...) corpora that clearly derive from typological differences between the languages, the most significant finding of this study is a high degree of lexical restrictiveness at the beginnings of CDS utterances in all three languages.

How many words is a bilingual 2-year-old supposed to know or say in each of her languages? Speech and language therapists or researchers lack the tools to answer this question, because several factors have an impact on bilingual language skills: gender, amount of exposure, mode of acquisition, socio-economic status and the distance between L1 and L2. Unfortunately, these factors are usually studied separately, making it difficult to evaluate their weight on a unique measure of vocabulary. The present study measures the (...) contribution of the following factors to the vocabulary scores of bilingual toddlers: i) gender; ii) sibling ranking; iii) relative amount of exposure to each language; iv) mode of exposure; v) SES; vi) linguistic distance; vii) language spoken between parents. Close to the child’s second birthday, parents of 278 UK-based bilinguals completed successively: a 100-word version of the Oxford-CDI, the CDI in the child’s Additional Language, a family questionnaire, and the Language Exposure Questionnaire. Thirty-six British-English-AL pairs were considered, with languages contrasted on a second-language-learning scale : for example, Dutch and French are close to British-English, while Polish or Cantonese are more distant. Data from the corpus were included in two mixed-effect models, one with the English scores in comprehension as the dependent variable, and the other with production scores. The seven factors listed above were included as predictors. The amount of English exposure was the strongest predictor of comprehension scores = 9.35, p <.005, β = 0.02, t = 3.08, p <.005), followed by the language that parents speak between themselves = 14.94, p <.001, β = 1.37, t = 3.76, p <.0005), linguistic distance = 6.92, p <.01, β = -0.74, t = -2.66, p <.01) and age = 4.86, p <.05, β = 0.55, t = 2.17, p <.05). In production, gender = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), amount of exposure to English = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), the language that parents speak between themselves = 11.85, p <.005, β = 1.09, t = 3.41, p <.001), and the mother’s occupation = 4.51, p <.05, β = 0.63, t = 2.13, p <.05) were the significant predictors. The more English parents use to address one another, the more English words the child says and understands. This surprising result could be simply explained by the fact that parents who speak English together are also more likely to speak English to their child. The main results of this study is that linguistic distance is a powerful predictor of toddlers’ vocabulary in English, with children learning two close languages growing their vocabulary faster than those learning distant languages.

In 2008, Susan L. Smith published “Mustard Gas and American Race-Based Human Experimentation in World War II.” Research, undertaken by the US Army, attempted to quantify the effect of mustard gas and othe chemical agents on people from different racial groups. This was based on the idea that different races would respond differently to the toxins, and in particular that this would be evident through dermal reaction. In other words, different skin color might mean different skin constitution. Some of (...) the testing seemed reasonable, since new chemicals and equipment had been developed since 1919, and the racial issue added another dimension to the research. On closer examination, the testing was primarily based on old chemical agents such as mustard gas, Lewisite and phosgene, and thus the extent of the testing seemed scientifically and medically unnecessary. The chemical agents had been developed, tested, used in battle, the wounded treated and the dead subjected to detailed pathological study. The major combatants in World War I had all committed extensive scientific resources to the study of these agents looking at both offensive and defensive aspects of their use, including toxicity testing. The U.S. Chemical Warfare Service had been formed in 1918 to specifically deal with issues such as toxicity tests, so why was the U.S. Army revisiting the subject of chemical weapons testing during World War II?

The paper is about the interpretation of opaque verbs like “seek”, “owe”, and “resemble” which allow for unspecific readings of their (indefinite) objects. It is shown that the following two observations create a problem for semantic analysis: (a) The opaque position is upward monotone: “John seeks a unicorn” implies “John seeks an animal”, given that “unicorn” is more specific than “animal”. (b) Indefinite objects of opaque verbs allow for higher-order, or “underspecific”, readings: “Jones is looking for something Smith is (...) looking for” can express that there is something unspecific that both Jones and Smith are looking for. Given (a) and (b), it would seem that the following inference is hard to escape, if the premisses are construed unspecifically and the conclusion is taken on its under- specific reading: Jones is looking for a sweater. Smith is looking for a pen. Smith is looking for something Jones is looking for. (shrink)

This paper critically evaluates central themes of values-based medicine (VBM). First, I discuss the 'non-descriptivist' conception of value judgments at the heart of VBM. According to it, no inferences can rationally be drawn from factual criteria to value judgments and the inferences that are naturally formed are a matter of human psychology. I argue, however, that it is an essential feature of value judgments that they are themselves subject to normative assessment. This implies an important role for an evaluatively rich (...) notion of psychology. Second, I discuss the role of 'dissensus' in VBM and argue that, although value judgments need not converge, the processes for exploring conflicting values must, themselves, be normatively assessable. Third, I examine how these aspects interact in complex real cases such as the case study of Diane Abbot. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Elizabeth Hanson-Smith AUGUSTINE'S CONFESSIONS: THE CONCRETE REFERENT The chief problem facing critics who would consider the Confessions as both a literary work and a philosophical treatise remains the connection between the first nine books, the autobiography, and the last four, the metaphysical speculations on time, eternity, epistemology, and theology. A persistent desire to justify the work as an aesthetic whole has led critics on a search for thematic (...) and structural unity; they have been more successful in the former endeavor than in the latter. The interpretation of the work's plot as a peregrinatio animae, a pilgrimage of the soul, is now generally accepted as definitive; but attempts to find structural unity within that broad outline have not progressed beyond Marrou's characterization of the work as a "musical composition."1 His analogy to music has not been anchored to any concrete structural features of the Confessions and does not illuminate the connections between its content and its form. I shall attempt to prove that a unified structural model for the development of the soul in the Confessions does indeed exist and is outlined in Augustine's earlier discursive work, the De quantitate animae.2 The seven degrees or steps (gradus) of the soul's ascent to God, as sketched in the De quantitate, are deliberately fleshed out and translated into a mimetic, narrative version in the Confessions. Placing the two works side by side gives us a unique opportunity to examine a typically medieval literary form, the educative journey, in its relationship to its philosophical premises. Such a study reveals the inner formal unity of the literary work and, further, provides us with significant evidence for a re-examination of Augustine's Neo-Platonism, his supposed dualism, and his influence on later works, both literary and philosophical. In the Confessions we see one of the earliest Christian blendings of several models: first, the educative journey, the archetypal pattern familiar from the Odyssey, the Aeneid, and even The Golden Ass of Apuleius. Augustine's version, like later medieval cosmologies, also 176 Elizabeth Hanson-Smith1 77 includes a vision of the cosmic order and its relationship to human order, elements of significance in pagan philosophical works such as the Timaeus and the Dream of Scipio. But Augustine's journey also depends upon the Judeo-Christian conception of history as a series of figurae or types of the Messiah: the protagonist of the Christian educative journey joins thefigurae of the Biblical past. Christ's incarnation as Mansoul and his life on earth are the pattern of universal history from Fall to Apocalypse; Christ's life becomes a figurative pattern for the actions of Everyman.3 The Confessions is one of the earliest Christian works to apply this pattern in a narrative context. Augustine was also preoccupied with the Hexaemeron, the six days of creation and the seventh of rest. He views the exegesis of Genesis as an explanation of all subsequent life; the Ages of Man recapitulate the days of creation, as do the sacraments and the seven steps in the ascent of the soul. Thus, to the figurative pattern of Christ's "pilgrimage" from creating Logos to Incarnate God and finally to judge at the Second Coming, Augustine applies the schematic seven-fold ascent found in the De quantitate: the soul passes through the ascending steps of animation, sense, art, religion, tranquillity, initiation, and contemplation—each of which is figured by or patterned on a stage in Christ's life, as represented by the sacraments, and each of which, further, reflects a segment of universal history. The seven steps are not simply the movement of the individual soul, but the progress of Mansoul on its journey to Apocalypse. The stylistic differences between the two works—one an exposition written as Socratic dialogue, the other a metaphorical personal narrative —will no doubt give rise to differing interpretations; but one may, I think, object to certain details I suggest while still agreeing that the De quantitate provides the structuring model. Let me first define the major areas of difference between the two works. In the De quantitate, each of the levels or steps of the soul takes on a discrete, separate... (shrink)

When we from what may be called Aristotle's Cosmology turn to his work traditionally called the Metaphysics, we are faced with something—an inquiry or doctrine—of a surprisingly different character. There what we find is the exposition of a sort or degree of knowledge superior to that of the Sciences. This is what we call his metaphysics, but he does not so name it; he names it Wisdom, or Theoretical Wisdom. At times he calls it First Philosophy, or, again, Theology. It (...) is par excellence knowledge, the consummate achievement of theoretic or cognitive power. It is the supreme Science, scientia scientiarum. Of what is it knowledge? It is knowledge not about, but of, whatsoever is real, really real, and of its universal and necessary attributes. The latter are distinct from one another, and from that to which they indissolubly belong, and metaphysics apprehends all this in its distinctions and interconnections. Further, it is a knowledge of itself, a knowledge of knowledge, and so a Wissenschaftslehre, or“super-Logic.” Finally, it is knowledge commensurate with the real Universe as a whole, so that nothing which is genuinely a part of that escapes its view.

By “voluntary actions” we mean the actions that are willed to be done in a prior volition, and which are realized by our own power, rather than by an external force. Running up the slope of a hill for exercise is a voluntary action, but falling down the slope is not. The volition, or the “decision” to undertake an action, may be the outcome of a deliberation about which of several actions to undertake, or it may be a spontaneous decision (...) to engage in a certain action, without being preceded by a deliberative process.

In Episode 1, we introduced the very idea of a negation-incomplete formalized theory T . We noted that if we aim to construct a theory of basic arithmetic, we’ll ideally like the theory to be able to prove all the truths expressible in the language of basic arithmetic, and hence to be negation complete. But Gödel’s First Incompleteness Theorem says, very roughly, that a nice theory T containing enough arithmetic will always be negation incomplete. Now, the Theorem comes in two (...) flavours, depending on whether we cash out the idea of being ‘nice enough’ in terms of (i) the semantic idea of T ’s being a sound theory, or (ii) the idea of odel’s own T ’s being a consistent theory which proves enough arithmetic. And we noted that G¨. (shrink)

Dans cet article je propose d'exprimer et de défendre une conception des pratiques et du domaine de discours mathématiques qui soit sensible, d'une part, au pluralisme des relations entre pratiques inférentielles et intérêts, et d'autre part, à la structure objective et déterminante des concepts mathématiques. J'ébauche tout d'abord une caractérisation générale des pratiques, pour ensuite préciser certains phénomènes propres aux pratiques mathématiques. Suit un recensement des idées qui se dégagent des arguments pluralistes, et de celles qui sont à retenir. Mais (...) je défends par la suite la nécessité d'une forme de réalisme mathématique, qui toutefois ne peut être le réalisme d'objets que prônent les partisans de l'argument d'indispensabilité. Je défends plutôt un réalisme des concepts, soutenu par ce que je baptise l'« argument de la contrainte ». (shrink)

France is the home of the Declaration of the Rights of Man, yet women did not vote until 1945, many years later than their peers in other countries. In a country where civil rights had long been a rallying cry, women were not second-class citizens--they were not citizens at all. In this fascinating and ground-breaking study, Paul Smith assesses why Frenchwomen were repeatedly refused the rights of citizenship and examines the political relationships established by French feminists in order to (...) achieve their goal: one woman, one vote.
