Costs and benefits of tool-use on the perception of reachable space

Previous studies have shown that using a tool modifies in a short time-scale both near-body space perception and arm-length representation in the body schema. However, to date no research has specifically investigated the effect of tool-use on an action-related perceptual task. We report here a study assessing the effect of tool-use on the perception of reachable space for perceptual estimates made in reference to either the tool or the hand. Using the tool on distal objects resulted in an extension of perceived reachable space with the tool and reduced the variability of reachability estimates. Tool use also extended perceived reachable space with the hand, but with a concomitant increase of the variability of reachability estimates. These findings suggest that tool incorporation into the represented arm following tool-use improves the anticipation of action possibilities with the tool, while hand representation becomes less accurate.     

Logical Metonymy Resolution in a Words‐as‐Cues Framework: Evidence From Self‐Paced Reading and Probe Recognition

Logical metonymy resolution (begin a book → begin writing a book) has traditionally been explained either through complex lexical entries (qualia structures) or through the integration of the implicit event via post‐lexical access to world knowledge. We propose that recent work within the words‐as‐cues paradigm can provide a more dynamic model of logical metonymy, accounting for early and dynamic integration of complex event information depending on previous contextual cues (agent and patient). We first present a self‐paced reading experiment on German subordinate sentences, where metonymic sentences and their paraphrased version differ only in the presence or absence of the clause‐final target verb (Der Konditor begann die Glasur → Der Konditor begann, die Glasur spreading the icing). Longer reading times at the target verb position in a high‐typicality condition (baker + icing → spread ) suggest that we make use of knowledge activated by lexical cues to build expectations about events. The early and dynamic integration of event knowledge in metonymy interpretation is bolstered by further evidence from a second experiment using the probe recognition paradigm. Presenting covert events as probes following a high‐typicality or a low‐typicality metonymic sentence (Der Konditor begann die Glasur → SPREAD ), we obtain an analogous effect of typicality at 100 ms interstimulus interval.     

A New Semantics for Systems of Logic of Essence

The purpose of the present paper is to provide a way of understanding systems of logic of essence by introducing a new semantic framework for them. Three central results are achieved: first, the now standard Fitting semantics for the propositional logic of evidence is adapted in order to provide a new, simplified semantics for the propositional logic of essence; secondly, we show how it is possible to construe the concept of necessary truth explicitly by using the concept of essential truth; finally, Fitting semantics is adapted in order to present a simplified semantics for the quantified logic of essence.     

The intuitive concept of art

A great deal of work in analytic philosophy of art is related to defining what counts as art. So far, cognitive approaches to art have almost entirely ignored this literature. In this paper, I discuss the role of intuition in analytic philosophy of art to show how an empirical research program on art could take advantage of existing work in analytic philosophy. I suggest that the first step of this research program should be to understand how people intuitively categorize something as art. Drawing on results from cognitive science and analytic philosophy, I show that the intuitive categorization of an artifact as art rests on the intentions attributed (frequently implicitly) to the creator of the artifact based both on its appearance and on background knowledge. I discuss how the issue of categorization is related to other empirical issues concerning our relationship to works of art, such as perception, appreciation, interpretation, and evaluation.     

Quality of Life,Anxiety and Depression in Soft Tissue Sarcomas as Compared to More Common Tumours: An Observational Study

The aim of this study is to compare the quality of life and the levels of anxiety and depression in a relatively large group of subjects undergoing chemotherapy for soft tissue sarcoma and a control group of subjects undergoing chemotherapy for the most common types of cancer. 56 soft tissue sarcoma affected patients and 56 patients with common tumours, homogeneous in regards to stages of disease and sociodemographic characteristics, were enrolled in two oncological centres in Turin, Italy. Quality of life was assessed by Functional Assessment of Cancer Therapy-General and anxiety and depression by Hospital Anxiety and Depression Scale. All patients had ongoing chemotherapy. The comparison between the two groups shows no difference in either quality of life or in anxiety and depression. There are instead gender differences, since females in the group of common tumours show higher levels of anxiety in comparison to those affected by sarcomas, while males show, at a lower degree, the opposite trend. This study suggest that levels of Quality of Life, anxiety and depression are similar in rare and common tumours. The majority of patients are able to cope with the disease in an adaptive manner. However, for some patients the disease poses a threat to their physical and mental integrity; psychological support of these patients may reduce the development of significant morbidity and help patients to better manage the course of the disease and the effects of the treatment.     

Objects,numbers, fingers,space: clustering of ventral and dorsal functions in young children and adults

In the primate brain, sensory information is processed along two partially segregated cortical streams: the ventral stream, mainly coding for objects' shape and identity, and the dorsal stream, mainly coding for objects' quantitative information (including size, number, and spatial position). Neurophysiological measures indicate that such functional segregation is present early on in infancy, and that the two streams follow independent maturational trajectories during childhood. Here we collected, in a large sample of young children and adults, behavioural measures on an extensive set of functions typically associated with either the dorsal or the ventral stream. We then used a correlational approach to investigate the presence of inter‐individual variability resulting in clustering of functions. Results show that dorsal‐ and ventral‐related functions follow two uncorrelated developmental trajectories. Moreover, within each stream, some functions show age‐independent correlations: finger gnosis, non‐symbolic numerical abilities and spatial abilities within the dorsal stream, and object and face recognition abilities within the ventral stream. This pattern of clear within‐stream cross‐task correlation seems to be lost in adults, with two notable exceptions: performance in face and object recognition on one side, and in symbolic and non‐symbolic comparison on the other, remain correlated, pointing to distinct shape recognition and quantity comparison systems.
