Accounting for the Data: Intuitions in Moral Theory Selection

Reflective equilibrium is often credited with extending the idea of accounting for the data from its familiar home in the sciences to the realm of moral philosophy. But careful consideration of the main concepts of this idea—the data to be accounted for and the kind of accounting it is appropriate to expect of a moral theory—leads to a revised understanding of the “accounting for the data” perspective as it applies to the discipline of moral theory selection. This revised understanding is in tension with reflective equilibrium and actually provides more support for the alternative method of moral theory selection that has been termed ‘practical equilibrium’.     

The effect of spatial organization of targets and distractors on the capacity to selectively memorize objects in visual short-term memory

We conducted a series of experiments to explore how the spatial configuration of objects influences the selection and the processing of these objects in a visual short-term memory task. We designed a new experiment in which participants had to memorize 4 targets presented among 4 distractors. Targets were cued during the presentation of distractor objects. Their locations varied according to 4 spatial configurations. From the first to the last configuration, the distance between targets’ locations was progressively increased. The results revealed a high capacity to select and memorize targets embedded among distractors even when targets were extremely distant from each other. This capacity is discussed in relation to the unitary conception of attention, models of split attention, and the competitive interaction model. Finally, we propose that the spatial dispersion of objects has different effects on attentional allocation and processing stages. Thus, when targets are extremely distant from each other, attentional allocation becomes more difficult while processing becomes easier. This finding implicates that these 2 aspects of attention need to be more clearly distinguished in future research.     

Maps and Absent Symbols

absence is the claim that, if a symbol appears on a map, then absence of the symbol from some map coordinate signifies absence of the corresponding property from the corresponding location. This claim is highly intuitive and widely endorsed. And if it is true, then cartographic representation is strikingly different from linguistic representation. I argue, however, that absence is false of various maps and that we have no reason to believe it is true of any maps. The intuition to the contrary results from mistaking what a map simply conveys for what it literally represents.     

Dialetheism and the Impossibility of the World

This paper first offers a standard modal extension of dialetheic logics that respect the normal semantics for negation and conjunction, in an attempt to adequately model absolutism, the thesis that there are true contradictions at metaphysically possible worlds. It is shown, however, that the modal extension has unsavoury consequences for both absolutism and dialetheism. While the logic commits the absolutist to dialetheism, it commits the dialetheist to the impossibility of the actual world. A new modal logic AV is then proposed which avoids these unsavoury consequences by invalidating the interdefinability rules for the modal operators with the use of two valuation relations. However, while using AV carries no significant cost for the absolutist, the same isn't true for the dialetheist. Although using AV allows her to avoid the consequence that the actual world is an impossible world, it does so only on the condition that the dialetheist admits that she cannot give a dialetheic solution to all self-referential semantic paradoxes. Thus, unless there are any further available modal logics that don't commit her to the impossibility of the actual world, the dialetheist is faced with a dilemma. Either admit that the actual world is an impossible world, or admit that her research programme cannot give a comprehensive solution to the self-referential paradoxes.     

An Elicited‐Production Study of Inflectional Verb Morphology in Child Finnish

Many generativist accounts (e.g., Wexler, 1998) argue for very early knowledge of inflection on the basis of very low rates of person/number marking errors in young children's speech. However, studies of Spanish (Aguado‐Orea & Pine, 2015) and Brazilian Portuguese (Rubino & Pine, 1998) have revealed that these low overall error rates actually hide important differences across the verb paradigm. The present study investigated children's production of person/number marked verbs by eliciting present tense verb forms from 82 native Finnish‐speaking children aged 2;2–4;8 years. Four main findings were observed: (a) Rates of person/number marking errors were higher in low‐frequency person/number contexts, even excluding children who showed no evidence of having learned the relevant morpheme, (b) most errors involved the use of higher frequency forms in lower frequency person/number contexts, (c) error rates were predicted not only by the frequency of person/number contexts (e.g., 3sg > 2pl) but also by the frequency of individual “ready‐inflected” lexical target forms, and (d) for low‐frequency verbs, lower error rates were observed for verbs with high phonological neighborhood density. It is concluded that any successful account of the development of verb inflection will need to incorporate both (a) rote‐storage and retrieval of individual inflected forms and (b) phonological analogy across them.
