Converging Hands or Converging Minds?

چکیده
Interlocutors sometimes repeat each other’s representational hand gestures. We investigated if this is a case of direct mimicry of form, or whether perceiving a gesture gives rise to a semantic representation, which subsequently informs gesture production. For this we used an interactive route description task, in which a confederate’s gestures indicated the route in either the vertical or the horizontal plane and either with one or four fingers extended as an index. We found that perceiving vertical gestures led to an increase not only in participants’ production of vertical gestures, but also in their use of one finger as an index, suggesting that seeing vertical gestures caused participants to think of the route as on a map, which led them to point with one finger (as is common on a map) rather than four. Our results support the notion that repetition of meaningful gesture forms results from converging semantic representations.

Heat Transfer Analysis of Nanofluid Flow with Porous Medium through Jeffery Hamel Diverging/Converging Channel
In this paper, flow and heat transfer of nanofluid through a converging or diverging channel with porous medium is investigated. The fluid constantly flows under the effect of magnetic field through the channel. The diverging/converging fluid motion is modeled using the momentum and energy equations. The influence of some parameters such as opening channel angle, Reynolds number and Darcy’s num...
متن کاملScale Effects on the Discharge Coefficient of Ogee Spillway with an Arc in Plan and Converging Training Walls
Dam spillways are the structures that lead rightly and safely the outflow downstream, so that the dam integrity can be guaranteed. Many accidents with dams have been caused by an inadequate spillway design or insufficient capacity. To accurately respond the hydraulic spillways, designers use physical modeling for designing this kind of structures. The scale effect in the spillway modeling, as a...
متن کاملPerceiving Minds and Gods: How Mind Perception Enables, Constrains, and Is Triggered by Belief in Gods.
Most people believe in the existence of empirically unverifiable gods. Despite apparent heterogeneity, people's conceptions of their gods center on predictable themes. Gods are overwhelmingly represented as intentional agents with (more or less) humanlike mental lives. This article reviews converging evidence suggesting that this regularity in god concepts exists in part because the ability to ...
