Abstract:There is evidence that children learn both proper names and count nouns from the outset of lexical development. Furthermore, children's first proper names are typically words for people, whereas their first count nouns are commonly terms for other objects, including artifacts. I argue that these facts represent a challenge for two well‐known theoretical accounts of object word learning. I defend an alternative account, which credits young children with conceptual resources to acquire words for both individual objects and object categories, and (...) conceptual biases to construe some objects (notably people) as individuals in their own right and most other objects as instances of their category.

The celebrity effect is the well-documented phenomenon in which people ascribe an enhanced worth to artefacts owned by famous individuals. This effect has been attributed to a belief in psychological contagion, the transmission of a person’s essence to an object via contact. We examined people’s judgments of the persisting worth of celebrity-owned artefacts following transformations of their parts/material and found that the celebrity effect was evident only for post-transformation artefacts that were composed of parts/material that had direct physical contact with (...) the celebrity. Insofar as the celebrity effect arises from psychological contagion, the findings suggest that the essence imparted to a celebrity-owned artefact is conceived as akin to a residue deposited in/on the object rather than a germ capable of spreading in an indirect manner to new parts/material added to the object. The results illuminate the nature of psychological contagion and offer insight into how best to preserve the value of historically important artefacts. (shrink)

In the United States, approximately 2.53 million people sustain a concussion each year. Relative to adults, youth show greater cognitive deficits following concussion and a longer recovery. An accurate and reliable imaging method is needed to determine injury severity and symptom resolution. The primary objective of this study was to characterize concussions with diffusion tensor imaging. This was performed through a normative Z-scoring analysis of DTI metrics, fractional anisotropy, axial diffusivity, and radial diffusivity, to quantify patient-specific injuries and identify commonly (...) damaged brain regions in paediatric concussion patients relative to healthy controls. It was hypothesized that personalizing the detection analysis through normative Z-scoring would provide an understanding of trauma-induced microstructural damage. Concussion patients were volunteers recruited from the Emergency Department of the McMaster Children’s Hospital with a recent concussion, 9 males and 17 females, mean age 14.22 ± 2.64, while healthy paediatric brain DTI datasets were obtained from an MRI data repository. Significant abnormalities were commonly found in the longitudinal fasciculus, fronto-occipital fasciculus, and corticospinal tract, while unique abnormalities were localized in a number of other areas reflecting the individuality of each child’s injury. Total injury burden, determined by the number of regions containing outliers per DTI metric per patient, was used as the metric to quantify the overall injury severity of each patient. The primary outcome of this analysis found that younger patients experienced a significantly greater injury burden when measured using fractional anisotropy. These results show that DTI was able to detect microstructural changes caused by concussion, on a per-person basis, and has the potential to be a useful tool for improving diagnostic accuracy and prognosis of a concussion.

It is often said in physics that if two models of a theory are related by a symmetry, then the two models provide (or could provide) two different representations of the very same situation, alike the case of two maps of different color for the very same city. It is also said that the situations represented by two models of a theory are indiscernible in some ways when the models in question are related by a symmetry of the theory, just (...) like the situation in the interior of the cabin of a train when the train is at rest in the station is empirically indiscernible from the situation in the interior when the train is moving uniformly (in classical mechanics, these two situations are represented by two models related by a boost). In recent years, philosophers of physics have focused a lot of attention in developing various principles that aim to elucidate these and similar remarks on symmetries, models, physical equivalence, and representation that are widespread in physics practice. The goal of the current article is to provide a critical review of these principles, and suggest a new framework for thinking about these kinds of questions. One important upshot of the paper is that questions of indiscernibility, and questions of the representational capacity of models, must be distinguished from one another. (shrink)

Traditional theories of associative learning have found no place for the possibility that the way in which events are perceived might change as a result of experience. Evidence for the reality of perceptual learning has come from those studied by learning theorists. The work reviewed in this book shows that learned changes in perceptual organization can in fact be demonstrated, even in experiments using procedures of the type on which associative theories have been based. These results come from procedures that (...) have been the focus of detailed theoretical and empirical analysis; and from this analysis emerges an outline of the mechanisms responsible. Some of these are themselves associative; others require the addition of nonassociative mechanisms to the traditional theory. The result is an extended version of associative theory which, it is argued, will be relevant not only to the experimental procedures discussed in this book but to the entire range of instances of perceptual learning.

The principle of sufficient reason threatens modal collapse. Some have suggested that by appealing to the indefinite extensibility of contingent truth, the threat is neutralized. This paper argues that this is not so. If the indefinite extensibility of contingent truth is developed in an analogous fashion to the most promising models of the indefinite extensibility of the concept set, plausible principles permit the derivation of modal collapse.

Recently some philosophers have defended the thesis that naturalness, or joint-carvingness, is an aim of belief. This paper argues that there is an important class of counterexamples to this thesis. In particular, it is argued that naturalness is not an aim of our beliefs concerning what is joint carving and what is not.

What is the connection between having a phenomenal property and knowing that one has that property? A traditional view on the matter takes the connection to be quite intimate. Whenever one has a phenomenal property, one knows that one does. Recently most authors have denied this traditional view. The goal of this paper is to defend the traditional view. In fact, I will defend something much stronger: I will argue that what it is for a property to be phenomenal is (...) for it to be a property one must know oneself to have when on has it. As we will see, this theory has a number of surprising and welcome upshots, suggesting that the traditional view has been unjustly maligned. (shrink)

Propositions represent the entities from which they are formed. This fact has puzzled philosophers and some have put forward radical proposals in order to explain it. This paper develops a primitivist account of the representational properties of propositions that centers on the operation of application. As we will see, this theory wins out over its competitors on grounds of strength, systematicity and unifying power.

Dunn, Geoffrey D As with last year's reflections, it is my intention to give a distinctly patristic flavour to what I write, drawing upon the rich tradition of the church in the youthful flush of its earliest centuries, a time also of great challenge, to see the enduring relevance and beauty of the insights of the earliest Christian preachers, commentators and authors.

Dunn, Geoffrey D In the past two weeks we have heard of covenants God made with people: the covenant with Noah symbolised by the rainbow and the covenant with Abraham symbolised by the stars in the night sky. God made fantastic promises and it would seem that God asked for little in return. Perhaps that is unfair. Noah had to suffer seeing the rest of humanity destroyed and Abraham endured the torment of preparing his son for sacrifice. They both (...) offered a significant display of faith and their descendants enjoyed the benefits. (shrink)

Dunn, Geoffrey D Older Catholics would have grown up hearing about the sacrifice of the Mass, while in the last fifty years we have increasingly spoken of the celebration of the eucharist. Of course, the eucharist is sacrifice, but it is other things besides, like meal and celebration, and the word 'sacrifice' is easy to misinterpret. For many of us the word 'sacrifice' conjures up thoughts of the killing and slaughter of animals or even people. It is true that (...) the word can mean this, but it has a much broader meaning. To sacrifice something is to remove it from the realm of the everyday and hand it over or dedicate it to some other purpose. Thus, a bloodless sacrifice, like the libation or pouring out of wine, is the offering up of something for someone else's use rather than one's own. Naturally, the killing of a living victim ensures that one cannot change one's mind later on and take it back, especially when the burnt sacrificial animal has often then been eaten by those who had participated in or witnessed the ritual slaughter.

Dunn, Geoffrey D We see in Mark's Gospel an interest in Jesus reaching out beyond the Jewish people to bring the good news to other peoples as well. One of the issues associated with that is the extent to which these other people need to adopt Jewish ways in order to become followers of Jesus. That is why, even though we are in a section of Mark's Gospel that deals with Jesus and the disciples, we have today's passage about (...) Jesus and the Jewish religious leaders, the Pharisees.

Dunn, Geoffrey D As a seminary student I was taught that a homily ought to end with a eucharistic link. Mature reflection leads me to conclude that the entire homily is itself the eucharistic link. It joins together the interplay of the life of the assembly and the Scriptures, on the one hand, and the great prayer of thanksgiving on the other. My reflections are missing the element of the life of the assembly, which can be supplied only by (...) individual preachers in touch with their communities, but hopefully they provide something of the reason why, on this particular occasion, the assembly can move on to offer God thanks.

Dunn, Geoffrey D Lent is a time of preparation for Easter. It developed during the fourth century as a time when sinners, who could no longer participate as full members of the church due to the serious and public nature of their offences, prepared for reconciliation with the church through penance, and adult catechumens, who were seeking to join the church as new members, prepared for initiation into the church. The season is a time of renewal of relationships for (...) the community, of renewal of our relationship with God and of renewal of our relationships with others. The central theme is conversion: a conversion as radical as reorienting one's whole life according to the gospel of Jesus, and as total as requiring the surrender of life. We surrender our old way of life and allow the Spirit to conform us to the new way of life as a disciple of Jesus. The Year A readings have a particular focus on the initiation of catechumens, who, at the start of Lent, celebrate the rite of election and enter the final period of purification and enlightenment before initiation at Easter. On the Third, Fourth, and Fifth Sundays the elect celebrate the scrutinies, when the community examines their readiness for initiation. The symbols of the Easter liturgy feature in the readings of these three Sundays: water, light, and life. (shrink)

Dunn, Geoffrey D One of my philosophy professors told me there were two sets of alternatives at the heart of philosophy, which is another way of saying that there are two fundamental choices between two different ways at the heart of understanding life. The years have proven, at least as far as I am concerned, just how insightful this observation was. The two sets of alternatives are one and many, and being and flux. The solemn feast of Pentecost, the (...) last day of our Easter season, gives us the opportunity to reflect on the first set: one and many. When we look out at the world, are we the kind of persons who see what we have in common with others and see what unites us, or are we the kind of persons who first notice the differences between us and other people: either our gender, or our skin colour, or our language, or our religion, or our social status, or our nationality, or our education, or our occupation? There are so many things that make us different from one another that it is a rare person who is able to focus on what makes us one. (shrink)

Studies of conditioning in simple systems are best interpreted in terms of the formation of excitatory links. The mechanisms responsible for such conditioning contribute to the associative learning effects shown by more complex systems. If a dual-system approach is to be avoided, the best hope lies in developing standard associative theory to deal with phenomena said to show propositional learning.

As my time writing scripture reflections for this journal has drawn to an end, it is a good opportunity to reflect more theoretically about the nature of homiletic preaching today. My first peer-reviewed publication was on this topic. Since then I have returned on occasion to investigate preaching in the early Christian centuries both on its own terms qua preaching and as source material for theological expression. It is a matter worthy of fresh reflection, because in the twenty years since (...) the publication of the article in 'Worship' there have been new documents issued from Rome, which in turn have given rise to fresh statements from bishops' conferences. The question is: has there been much change in the way the nature of a homily is understood over those past twenty years, and how does that align with the 'Worship' article? The argument advanced here is that these recent documents reveal a multiplicity of understandings of the purpose of the Sunday liturgical homily. (shrink)

We continue where we left off from last Sunday with Jesus establishing the ethical foundations of the new Israel. Hypocrisy is really one of the most distasteful of human characteristics and in today's gospel passage Jesus confronts it head on. Hypocrisy is the real 'fake news', for it is nothing other than a sham and a pretence that we are something that we really are not, a contrivance that we are better than others when we are not, a sanctimonious false (...) virtue that we have the right to point out the faults of others while leaving our own failings untouched. When we are the victim of someone else's hypocrisy we feel the injustice and unfairness, we feel the betrayal and deception, we feel the put-down and rejection. (shrink)

It is not specified in Mark's Gospel where the ascension of Jesus takes place, although the last location specified is Jerusalem. Nor are we given a time frame for how long after the resurrection it occurred. In Matthew we also have no time frame, but the ascension is located in the north, in Galilee. In the second half of Luke we are told that the ascension took place forty days after the resurrection, and in the first half we are told (...) that it took place at Bethany, a small village just outside of Jerusalem. In the last words Jesus speaks to his followers he connects his ascension back to his death and resurrection. He also connects the mission of the church, in bringing the message of forgiveness to the world and the giving of the Spirit at Pentecost, to his death and resurrection. (shrink)

In chapter 14 of Luke's Gospel we have several stories about table fellowship put together and several sayings of Jesus that are added as maxims to conclude the stories, even though originally they were probably used in a different context. We find the first maxim about those who exalt themselves being humbled and those who humble themselves being exalted attached to different material in Matthew 23. We have just heard the first of those two table fellowship stories, which are found (...) in Luke only, but the third is going to be left out of our liturgy readings entirely. (shrink)

The encounter between Jesus and the rich young man in Mt. 19,16-30 (with parallels in Mc. 10,17-31 and Lc. 18,18-30) provides the setting for the teachingon the attaining of perfection, which is presented as a three-step process: the selling of one’s possessions, the distribution of the proceeds to the poor, andthe following of Christ (Mt. 19,21; Mc. 10,21; Lc. 18,22; and the unique Lukan saying in 12,33). It was a passage to which Jerome appealed frequently in hiswritings and which Finn, (...) in his recent monograph, believes demonstrates Jerome’s extreme views. In this paper I shall examine Jerome’s references to this biblical passage in his letters and treatises to evaluate whether the first two steps in the process (self-dispossession and almsgiving) were consideredequally virtuous by Jerome.
