Experimental philosophers,conceptual analysts,and the rest of us

Abstract

Theories of personal identity purport to specify truth conditions for sentences of the form ‘x‐at‐t_i is the same person as y‐at‐t_j. Most philosophers nowadays agree that such truth conditions are to be stated in terms of psychological continuity. However; opinions vary as to how the notion of psychological continuity is to be understood. In a recent contribution to this journal, Slors offers an account in which psychological continuity is spelled out in terms of narrative connectedness between mental states.The present paper argues that Slors’ theory either is no theory of personal identity at all or is too weak.Towards the end of the paper, it is indicated how the problem uncovered for Slors’ theory may be avoided.     

What is the future for tool-specific generalized motor programs?

A key issue in cognitive sciences is to understand the cognitive bases of human tool use. Answers have been provided by two competing approaches. The manipulation-based approach assumes that humans can use tools because of the ability to store sensorimotor knowledge about how to manipulate tools. By contrast, for the reasoning-based approach, human tool use is based on the ability to reason about physical object properties. Recently, Caruana and Cuccio proposed a kind of reconciliation, based on the distinction between three types of abductive inference, involving a different contribution of motor and cognitive elements: Automatic abduction (motor + and cognitive-), abduction by selection (motor ± and cognitive±) and creative abduction (motor- and cognitive+). This perspective offers new interesting avenues. Nevertheless, it is also subject to several theoretical and epistemological limitations, which make it in its present form inappropriate for the study of the cognitive bases of human tool use. This article aims to discuss these limitations.     

Integration of parafoveal orthographic information during foveal word reading: beyond the sub-lexical level?

Prior research has shown that processing of a given target word is facilitated by the simultaneous presentation of orthographically related stimuli in the parafovea. Here we investigate the nature of such spatial integration processes by presenting orthographic neighbours of target words in the parafovea, considering that neighbours have been shown to inhibit, rather than facilitate, recognition of target words in foveal masked priming research. In Experiment 1, we used the gaze-contingent boundary paradigm to manipulate the parafoveal information subjects received while they fixated a target word within a sentence. In Experiment 2, we used the Flanking Letters Lexical Decision paradigm to manipulate parafoveal information while subjects read isolated words. Parafoveal words were either a higher-frequency orthographic neighbour of targets words (e.g., blue-blur) or a high-frequency unrelated word (e.g., hand-blur). We found that parafoveal orthographic neighbours facilitated, rather than inhibited, processing of the target. Thus, the present findings provide further evidence that orthographic information is integrated across multiple words and suggest that either the integration process does not enable simultaneous access to those words’ lexical representations, or that lexical representations activated by spatially distinct stimuli do not compete for recognition.     

A demonstration of dual-task performance without interference in some older adults

Highly efficient dual-task processing is demonstrated when reaction time to each of two tasks does not differ between the dual-task situation and the single-task situation. This has been demonstrated reliably in younger adults; nevertheless, the two extant studies of extensive dual-task training did not find evidence for it in any elderly adult. The origins of age-related differences after training were explored in a study in which the stimuli for the two tasks were perfectly redundant although two distinct responses were required. The dual-task situation thus greatly reduced the demands of stimulus categorization while still requiring two response selections and two response executions. After only limited training 8 of 8 younger adults and 5 of 8 older adults showed performance consistent with highly efficient processing. Three older adults failed to show this even after 12 training sessions. The results implicate stimulus categorization more than response selection as an important locus of inefficient dual-task processing, particularly for older adults.     

Early- and late-onset blindness both curb audiotactile integration on the parchment-skin illusion

It has been shown that congenital blindness can lead to anomalies in the integration of auditory and tactile information, at least under certain conditions. In the present study, we used the parchment-skin illusion, a robust illustration of sound-biased perception of touch based on changes in frequency, to investigate the specificities of audiotactile interactions in early- and late-onset blind individuals. Blind individuals in both groups did not experience any illusory change in tactile perception when the frequency of the auditory signal was modified, whereas sighted individuals consistently experienced the illusion. This demonstration that blind individuals had reduced susceptibility to an auditory-tactile illusion suggests either that vision is necessary for the establishment of audiotactile interactions or that auditory and tactile information can be processed more independently in blind individuals than in sighted individuals. In addition, the results obtained in late-onset blind participants suggest that visual input may play a role in the maintenance of audiotactile integration.     

Religion as Cultural Models: Developing an Emic Measure of Religiosity

Despite a century's worth of work, lacunae remain in our understanding of the religion‐health relationship. Scholars in this field have called for increasingly sophisticated conceptualizations of religiosity that refine its connection to well‐being, accounting for both positive and negative associations, while being sensitive to the cultural variations in the experience of religion. This article argues that cognitive anthropological methods provide a novel approach to these issues by conceptualizing aspects of religion as culturally shared “styles of life.” Specifically, the combined approaches of cultural consensus and cultural consonance provide an emically valid measure of religiosity that is then linked to health through the psychosocial stress paradigm. Utilizing research among Brazilian Pentecostals within the state of São Paulo, this intrareligious study evaluates the predictive power of religious cultural consonance relative to widely used and established religiosity scales. Religious consonance is found to have a stronger correlation with psychological well‐being than comparable measures, suggesting that existing standardized measures miss important dimensions of the religion‐health relationship. As such, this article outlines an important area of collaboration between anthropologists and other religion‐health researchers.     

Object manipulability affects children’s and adults’ conceptual processing

Research on kinds of concepts indicates that children use perceptual and functional information differently to form natural and artifact concepts. Beyond object domain, object manipulability appears to be a decisive factor in adult conceptual processing. Thus, the effect of object manipulability on conceptual processing was tested in 5- and 7-year-olds and adults using a picture matching task. Reaction times for identifying conceptual relations on the basis of perceptual similarity (e.g., jacket-coat) and contextual/functional information (e.g., jacket-hanger) were analyzed according to object manipulability and domain. Both children and adults were faster to identify contextual/functional relations for manipulable than for nonmanipulable objects. Conversely, they were faster to identify perceptual similarity relations for nonmanipulable than for manipulable objects, particularly for natural concepts. Results reveal an early distinction between concepts of manipulable and nonmanipulable objects. Implications for further research on concept formation and for embodied views of concepts are discussed.     

A non-Bergsonian Bachelard

In this essay, Perraudin sets out to contrast the competing philosophies of time and imagination of two major French thinkers of the twentieth century: Henri Bergson (1859–1941) and Gaston Bachelard (1884–1962). Despite Bachelard’s polemical approach vis-à-vis philosophical tradition in his works on epistemology and poetics, his accounts of time and imagination have been shown by several critics to be significantly influenced and inspired by his predecessor. Perraudin nonetheless argues that Bachelard’s critique of Bergson’s theory of continuous temporality opens the way—through the subtle dialectics of his “philosophy of no”—to more prolific, and as yet untapped, therapeutic possibilities in our understanding of time and imagination than Bergson’s accounts of continuum of the élan vital had managed to reveal. This translated text is a revised version of Jean Francois Perraudin’s “Un Bachelard Non-Bergsonien,” published in Gaston Bachelard: Du rêveur ironiste au pédagogue inspiré (Gaston Bachelard: From Ironic Dreamer to Inspired Educator). Ed. Jean Libis. Dijon: Centre Regional de Documentation Pédagogique, 1984, pp. 61–76.

Overproduction timing errors in expert dancers

The authors investigated how expert dancers achieve accurate timing under various conditions. They designed the conditions to interfere with the dancers' attention to time and to test the explanation of the interference effect provided in the attentional model of time processing. Participants were 17 expert contemporary dancers who performed a freely chosen duration while walking and executing a bilateral cyclic arm movement over a given distance. The dancers reproduced that duration in different situations of interference. The process yielded temporal overproductions, validating the attentional model and extending its application to expert populations engaged in complex motor situations. The finding that the greatest overproduction occurred in the transfer-with-improvisation condition suggests that improvisation within a time deadline requires specific training.
