Mental Imagery in Translation Processes

The dynamics of interhemispheric compensatory processes in mental imagery.

The capacity to generate and analyze mental visual images is essential for many cognitive abilities. We combined triple-pulse transcranial magnetic stimulation (tpTMS) and repetitive TMS (rTMS) to determine which distinct aspect of mental imagery is carried out by the left and right parietal lobe and to reveal interhemispheric compensatory interactions. The left parietal lobe was predominant in...

Mental Imagery in Synaesthesia

Mental imagery

Our ability to be conscious of the world around us is often discussed as one of the most amazing yet enigmatic processes under scientific investigation today. However, our ability to imagine the world around us in the absence of stimulation from that world is perhaps even more amazing. Our capacity to re-experience objects or scenarios that we’ve encountered before, and to notice new things abo...

Mental Imagery in Artificial Agents

We present a model architecture for a basic form of mental imagery, based on an appearance based approach to view synthesis. This model architecture is developed for an experimental study in which an artificial agent learns how to associate the values of a set of posture variables and the corresponding view of its robotic gripper. Our model is fully adaptive and does not require any a priori in...

Extending Mental Imagery in Sigma

This article presents new results on implementing mental imagery within the Sigma cognitive architecture. Rather than amounting to a distinct module, mental imagery is based on the same primitive, hybrid mixed, architectural mechanisms as Sigma’s other cognitive capabilities. The work here demonstrates the creation and modification of compound images, the transformation of individual objects wi...
