The Influence of Shared Visual Context on the Successful Emergence of Conventions in a Referential Communication Task

Human communication is thoroughly context bound. We present two experiments investigating the importance of the shared context, that is, the amount of knowledge two interlocutors have in common, for the successful emergence and use of novel conventions. Using a referential communication task where black‐and‐white pictorial symbols are used to convey colors, pairs of participants build shared conventions peculiar to their dyad without experimenter feedback, relying purely on ostensive‐inferential communication. Both experiments demonstrate that access to the visual context promotes more successful communication. Importantly, success improves cumulatively, supporting the view that pairs establish conventional ways of using the symbols to communicate. Furthermore, Experiment 2 suggests that dyads with access to the visual context successfully adapt the conventions built for one color space to another color space, unlike dyads lacking it. In linking experimental pragmatics with language evolution, the study illustrates the benefits of exploring the emergence of linguistic conventions using an ostensive‐inferential model of communication.     

A longitudinal study of pain sensitivity and blood pressure in adolescent boys: results from a 5-year follow-up.

A growing literature has observed a significant reduction in pain sensitivity among hypertensive animals and humans. It is uncertain whether a reduced sensitivity to pain can be observed in nonnotensive individuals who go on to develop high blood pressure. Blood pressure (BP) was reassessed in one hundred fifteen 19-year-old boys initially tested at age 14, when they were also presented with a pain stimulus (mechanical finger pressure). Hierarchical regression analyses indicated that information regarding pain tolerance improved prediction of changes in systolic and diastolic blood pressure beyond that afforded by differences in BP at age 14, parental history of hypertension, and body mass index. These analyses suggest that pain sensitivity may be associated with physiological processes involved in the development of sustained high blood pressure.     

Making Sense of Sorai: How to Deal with the Contradictions in Ogyū Sorai's Political Theory

To understand the political theory—and especially its alleged modernity—of Ogyū Sorai, one of the most important philosophers of Tokugawa Japan, we need to understand the pivotal role that heaven, gods and spirits play in this theory. This is no easy task. This article will start with an analysis of the reasons of this difficulty: the numerous tensions and contradictions found in Sorai's remarks on the subject. Refusing to ignore one side of the story, refusing also to reach too quickly a verdict of inconsistency, it also questions the rare attempt at a unified interpretation undertaken by Maruyama Masao. The article suggests that the solution is to understand that Sorai needs to speak from two different perspectives on the Way: the external perspective of the sages who grasp the relationships between the Way and the natural world as purveyor of the raw materials the Way is made of, and the internal perspective of commoners who must accept everything that is in a Way. This permits us to rescue the positivist interpretation of Sorai advanced by Maruyama and much criticized in recent years.     

Visual Elaboration Scale as a measure of imagery

We studied the correlation of one measure of imagery ability, the Visual Elaboration Scale, with two others, absorption of image and effort required to form a mental image. Significant correlations were obtained between the Visual Elaboration Scale and the other scales, with the exception of Absorption for women.
