Majority merging by adaptive counting

The present paper introduces a belief merging procedure by majority using the standard format of Adaptive Logics. The core structure of the logic ADM ^c (Adaptive Doxastic Merging by Counting) consists in the formulation of the conflicts arising from the belief bases of the agents involved in the procedure. A strategy is then defined both semantically and proof-theoretically which selects the consistent contents answering to a majority principle. The results obtained are proven to be equivalent to a standard majority operator for bases with partial support.     

The representational space of numerical magnitude: illusions of length

In recent years, a growing amount of evidence concerning the relationships between numerical and spatial representations has been interpreted, by and large, in favour of the mental number line hypothesis--namely, the analogue continuum where numbers are spatially represented (Dehaene, 1992; Dehaene, Piazza, Pinel, & Cohen, 2003). This numerical representation is considered the core of number meaning and, accordingly, needs to be accessed whenever numbers are semantically processed. The present study explored, by means of a length reproduction task, whether besides the activation of lateralized spatial codes, numerical processing modulates the mental representation of a horizontal spatial extension. Mis-estimations of length induced by Arabic numbers are interpreted in terms of a cognitive illusion, according to which the elaboration of magnitude information brings about an expansion or compression of the mental representation of spatial extension. These results support the hypothesis that visuo-spatial resources are involved in the representation of numerical magnitude.     

‘Caesura’ as Bion’s discourse on method1

The author contends that Caesura, one of Bion’s last works, can be read as the equivalent of Descartes’s Discourse on Method. In this compact and complex text, the dictate of ‘methodical’ and ‘hyperbolic doubt’– so called because it is taken to the extreme form of application to the faculty of thought itself – which, for Descartes, represents the fundamental principle of philosophical and scientific research, is reflected in the formula of ‘transcending the caesura’. Bion directs his attention successively to the pairs of opposing concepts that structure psychoanalytic discourse and demonstrates their paradoxical and non‐separative logic. The binary system of producing meaning is deconstructed through the systematic use of non‐pathological – i.e. not static but dynamic – reversible perspective. A viewpoint that appears natural, self‐evident and primary is plunged into crisis and proves to be founded on what the punctuation mark of the slash excludes. Yet the new point of view does not supplant its predecessor, but supplements it. The conceptual opposition is not overturned, but merely destabilized in such a way as to maintain a creative tension that generates new thoughts. By this technique of wrong‐footing the reader, Bion achieves what is tantamount to a Kuhnian revolution: the transition from Freud’s semiotic or evidential paradigm to an aesthetic one, centred on emotional experience – to a ‘science of at‐one‐ment’. Working with the antithetical concepts of censorship and caesura, the author illustrates some clinical implications of this radical shift.     

Local Identity and the Role of Individual Differences in the Use of Natural Resources: The Case of Water Consumption1

A field study assessed the role of social value orientation (SVO) and identification with the local community on water conservation behavior in Italy. Participants (N = 758) completed a self‐reported questionnaire, during summer and Easter time. It was expected that SVO and local identification would affect cooperation in conserving water resources. Consistent with the hypotheses, the highest levels of voluntary cooperation were detected among prosocial persons with high local identity, while the lowest levels of cooperation were detected among proself persons with low local identity. Other factors (e.g., perception of local authority's legitimacy, place of residence, severity of water scarcity condition) did not affect the hypothesized interaction. The theoretical and practical implications of the findings are discussed.     

Impaired self-reflection in psychiatric disorders among adults: A proposal for the existence of a network of semi independent functions

Self-reflection plays a key role in healthy human adaptation. Self-reflection might involve different capacities which may be impaired to different degrees relatively independently of one another. Variation in abilities for different forms of self-reflection are commonly seen as key aspects of many adult mental disorders. Yet little has been written about whether there are different kinds of deficits in self-reflection found in mental illness, how those deficits should be distinguished from one another and how to characterize the extent to which they are interrelated. We review clinical and experimental literature and suggest four different forms of deficits in self-reflection: (a) sense of ownership of one’s own thoughts and actions, (b) emotional awareness, (c) distinction between fantasy and reality and (d) the integration of a range of different views of oneself and others. We propose how these different impairments in self-reflection are linked with one another.     

Phonological short-term store and the nature of the recency effect: Evidence from neuropsychology

The recency effect in immediate recall of lists of unrelated words was investigated in P.V., a left hemisphere-damaged patient, who had a grossly reduced auditory verbal span, attributed to a selective impairment of a phonological short-term store. No recency effect was evident in free recall of auditorily presented material. When the patient was instructed to recall the final items of the list first, the recency performance remained defective, even though P.V. was able to adopt a recall from end order. In the case of visual presentation, P.V.'s free recall performance was within the normal range and a clear recency occurred in the recall from end condition. These results are consistent with the view that the standard recency effect in immediate free recall of auditorily presented material represents the output of a phonological short-term store to which ordinal retrieval strategies, in P.V.'s case unimpaired, are applied. Finally, the contributions of the phonological short-term store and the process of rehearsal to the recency effect and to immediate memory span performance are discussed.
