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.

The Bible has influenced contemporary culture both positively and negatively. The present volume is a collection of papers that were discussed at an international colloquium on the use of the Bible in Ethics in the Department of Biblical Studies at the University of Sheffield in April 1995. Participants came from many parts of the world and from different backgrounds, and the papers reflect their varied interests and the contexts in which they work. The contributors, in addition to the three editors, (...) are John Barton, Bruce Birch, Mark Brett, Mark Chapman, David Clines, Philip Davies, Cheryl Exum, Stephen Fowl, Norman Gottwald, John Haldane, Walter Houston, Sharon Ringe, Chrisopher Rowland, Lisa Sowle Cahill and Gerald West.

Political liberals ask citizens not to appeal to certain considerations, including religious and philosophical convictions, in political deliberation. We argue that political liberals must include a demanding requirement of intellectual modesty in their ideal of citizenship in order to motivate this deliberative restraint. The requirement calls on each citizen to believe that the best reasoners disagree about the considerations that she is barred from appealing to. Along the way, we clarify how requirements of intellectual modesty relate to moral reasons for (...) deliberative restraint. And we argue against attempts to weaken our requirement of intellectual modesty by emphasizing those moral reasons. (shrink)

Psychopaths continue to be demonised by the media and estimates suggest that a disturbing percentage of the population has psychopathic tendencies. This timely and controversial new book summarises what we already know about psychopathy and antisocial behavior and puts forward a new case for its cause - with far-reaching implications. Presents the scientific facts of psychopathy and antisocial behavior. Addresses key questions, such as: What is psychopathy? Are there psychopaths amongst us? What is wrong with psychopaths? Is psychopathy due to (...) nature or nurture? And can we treat psychopaths? Reveals the authors' ground-breaking research into whether an underlying abnormality in brain development leaves psychopaths with an inability to feel emotion or fear. The resulting theory could lead to early diagnosis and revolutionize the way society, the media and the state both views and contends with the psychopaths in our midst. (shrink)

This introductory text divides into two sections - the subject of philosophy, and the history of western philosophy from the Greeks to the present day.

Empathy is a lay term that is becoming increasingly viewed as a unitary function within the field of cognitive neuroscience. In this paper, a selective review of the empathy literature is provided. It is argued from this literature that empathy is not a unitary system but rather a loose collection of partially dissociable neurocognitive systems. In particular, three main divisions can be made: cognitive empathy , motor empathy, and emotional empathy. The two main psychiatric disorders associated with empathic dysfunction are (...) considered: autism and psychopathy. It is argued that individuals with autism show difficulties with cognitive and motor empathy but less clear difficulties with respect to emotional empathy. In contrast, individuals with psychopathy show clear difficulties with a specific form of emotional empathy but no indications of impairment with cognitive and motor empathy. (shrink)

This article explores the teaching of Fratelli tutti as an integrating document of the papacy of Francis. Exploring the title as greeting and imperative, the authors make a case for exploring FT as both a development of the themes of earlier social encyclicals and as an attempt to explore an integral humanism for a new age facing economic, environmental, migratory, and social-conflictual challenges. The article lays out a summary of these main themes of Francis’s social teaching. Nonetheless, the authors conclude, (...) the integral planetary humanism that Francis calls for, and is so needed, is itself a radically incomplete project. A common home is not possible without a recognition of a common kinship, yet without deep reflection on women’s experience, the inclusion of women as full subjects and agents of CST, and greater attention to race, the document cannot fully embody the spirit and logic of its own message of gift, inclusion, and co-belonging.

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/ (...) Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)

We provide a justification for political liberalism’s Reciprocity Principle, which states that political decisions must be justified exclusively on the basis of considerations that all reasonable citizens can reasonably be expected to accept. The standard argument for the Reciprocity Principle grounds it in a requirement of respect for persons. We argue for a different, but compatible, justification: the Reciprocity Principle is justified because it makes possible a desirable kind of political community. The general endorsement of the Reciprocity Principle, we will (...) argue, helps realize joint political rule and relationships of civic friendship. The main obstacle to the realization of these values is the presence of reasonable disagreement about religious, moral, and philosophical issues characteristic of liberal societies. We show the Reciprocity Principle helps to overcome this obstacle. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What Emotional Responding Is to Blame It Might Not Be to ResponsibilityR. J. R. Blair (bio)Keywordsblame, responsibility, emotional responses, psychopathyIn this interesting paper, Levy argues that by failing the moral/conventional distinction task (Blair 1995), individuals with psychopathy show a fundamental inability to categorize moral harms and as such their moral responsibility for their actions is reduced. He argues that, although we might still wish to incarcerate such individuals to (...) prevent them inflicting further harm on others, we should be less enthusiastic to blame them for their actions.In many respects, I agree with much of Levy's treatise. I certainly do not regard ascriptions of blame as useful in my own work with this population. I believe that our goal should be to fully understand the nature of their emotional deficit to be able to treat it similarly to other researchers who work to treat other emotional disorders. To me, Levy's argument appears sound.However, I offer three considerations and raise questions within these considerations that might further the debate. First, not all rules involve care-based emotional responses to victims. As Levy notes, this is the origin of the moral/conventional distinction. The problem here is that we do consider someone responsible if they break a conventional transgression. The student talking in class is generally considered blameworthy for this action as long as they knew that the rule of not talking during the lesson applied to that classroom. Yet, there is no victim and no care-based emotional response. Here, the only thing necessary to ascribe blame and responsibility is that the individual knew that a rule exists. Given this holds for conventional transgressions, why must we necessarily make a special case, with respect to responsibility, for moral transgressions?I believe that Levy is fully aware of this concern. He specifically makes reference to moral responsibility and writes that:the kind and degree of wrongness, and therefore blame, which attaches to infringements of the rules [against double parking or line-jumping] is very different, and usually much less significant, than the kind and degree attaching to moral wrongs. For psychopaths, all offences are merely conventional, and therefore—from their point of view—none of them are all that serious.(2007, p. 132)But the danger here is that issues of blame and responsibility may become highly relativistic and hinge on the strength of the emotional reaction. This is a problem because, although we might judge someone as more blameworthy if he intentionally [End Page 149] runs over five people rather than one, do we really consider that there is a distinction in moral responsibility between these two cases? If not, might not responsibility relate to factual knowledge of the existence of the rule against the transgression rather than the emotional response to the transgression?Second, there is considerable debate regarding whether psychopathy represents a taxon or a continuum (e.g., Vasey et al. 2005; Edens et al. 2006). Assuming it does represent a continuum, then we have an additional concern. How little of an emotional response to the transgression reduces one's moral responsibility and blame? Is it only the very reduced (although usually not absent) levels of emotional response that are shown by individuals with psychopathy? Or should we consider moral responsibility and blame proportional to the level of the emotional response? If this latter option is adopted, then what should we do about individuals who show heightened emotional responses, for example, patients with specific anxiety disorders (Rauch, Shin, and Wright 2003)? There are already some data that inhibited children (a developmental precursor to some anxiety disorders; Kagan and Snidman 1999) show heightened conscience development (Asendorpf and Nunner-Winkler 1992). If such children commit moral transgressions, should we regard them as more morally responsible and more blameworthy than regular folks?Third, the issue of intention received little attention in this paper. I have been considered to show a similar lack of attention to intention in the past (Nichols 2002) and, moreover, in some respects the issue was of limited concern given Levy's main goals. However, I mention it because so much of whether we consider someone responsible for their actions and... (shrink)

Recent interest in emotion as the basis for moral development began with work involving individuals with psychopathic tendencies, and a recent paper with this population has allowed fresh insights (Glenn, Iyer, Graham, Koleva, & Haidt, 2009). Two main conclusions suggested by this paper are: (i) that systems involved in different forms of morality can be differentiated; and (ii) that systems involved in justice reasoning likely include amygdala and/or ventromedial prefrontal cortex, even if the specifics of their functional contribution to justice (...) development remain unidentified.
