Attention regulation and monitoring in meditation.

Trends Cogn Sci. 2008 Mar 6;

Authors: Lutz A, Slagter HA, Dunne JD, Davidson RJ

Meditation can be conceptualized as a family of complex emotional and attentional regulatory training regimes developed for various ends, including the cultivation of well-being and emotional balance. Among these various practices, there are two styles that are commonly studied. One style, focused attention meditation, entails the voluntary focusing of attention on a chosen object. The other style, open monitoring meditation, involves nonreactive monitoring of the content of experience from moment to moment. The potential regulatory functions of these practices on attention and emotion processes could have a long-term impact on the brain and behavior.

Action verbs and the primary motor cortex: A comparative TMS study of silent reading, frequency judgments, and motor imagery.

Neuropsychologia. 2008 Feb 2;

Authors: Tomasino B, Fink GR, Sparing R, Dafotakis M, Weiss PH

Single pulse transcranial magnetic stimulation (TMS) was applied to the hand area of the left primary motor cortex or, as a control, to the vertex (STIMULATION: TMS(M1) vs. TMS(vertex)) while right-handed volunteers silently read verbs related to hand actions. We examined three different tasks and time points for stimulation within the same experiment: subjects indicated with their left foot when they (i) had finished reading, (ii) had judged whether the corresponding movement involved a hand rotation after simulating the hand movement, and (iii) had judged whether they would frequently encounter the action verb in a newspaper (TASK: silent reading, motor imagery, and frequency judgment). Response times were compared between TMS(M1) and TMS(vertex), both applied at different time points after stimulus onset (DELAY: 150, 300, 450, 600, and 750ms). TMS(M1) differentially modulated task performance: there was a significant facilitatory effect of TMS(M1) for the imagery task only (about 88ms), with subjects responding about 10% faster (compared to TMS(vertex)). In contrast, response times for silent reading and frequency judgments were unaffected by TMS(M1). No differential effect of the time point of TMS(M1) was observed. The differential effect of TMS(M1) when subjects performed a motor imagery task (relative to performing silent reading or frequency judgments with the same set of verbs) suggests that the primary motor cortex is critically involved in processing action verbs only when subjects are simulating the corresponding movement. This task-dependent effect of hand motor cortex TMS on the processing of hand-related action verbs is discussed with respect to the notion of embodied cognition and the associationist theory.

PHYSICALITY AND INTERACTION
A Special Journal Issue of Interacting with Computers
Planned publication date: September 2008

Following the successful Physicality 2006 and Physicality 2007 International Workshops, which demonstrated the growing multi-disciplinary interest in this area of work, we invite submissions for this special issue on Physicality and Interaction for the interdisciplinary journal Interacting with Computers.

We live in an increasingly digital world yet our bodies and minds are naturally designed to interact with the physical. The products of the 21st century are and will be a synthesis of digital and physical elements embedded in new physical and social environments. As we design more hybrid physical/digital products, the distinctions for the user become blurred. It is therefore increasingly important that we understand what we gain, lose or confuse by the added digitality.

Augmented physical artefacts can be tailored and adapted to operate within a wide range of ecological settings. However, they also become more complex and require a fairly intensive design process to make them not simply practical and functional but also engaging. As a result, the need becomes even more pressing to comprehend the underlying computational intricacies, the physical form, properties and behaviour, the physical and social contexts, and the issues of aesthetics and creativity.

The issues in this field impact many areas of study: architecture, art, cognitive science, geography, human�computer interaction, philosophy, product design, sociology, tangible interface and ubiquitous computing.

We invite contributions that address physicality at various levels, including:

� design at the physical-digital frontier
� the philosophy of physicality
� artefact-focussed social interaction
� physically-inspired interaction in virtual worlds
� creativity and materiality
� interactive art and performance
� digital emulation of the physical
� the evolving role of digital artefacts in material culture

Via Networked Performance

Electrohype 2008 will present works by 5 - 8 artists or artist groups. To give the exhibition a broad perspective we are looking for Nordic as well as international artists. Electrohype has since the start in 1999 focused on what we choose to call computer based art. Art that runs of computers and utilizes the capacity of the computer to mix various media, allow interaction with the audience, or machines interacting with each others etc. in other words art that can not be transferred to “traditional” linear media. This might seem as a narrow approach but we have discovered that it gives us a better focus on a genre that in no way is narrow.

We are not looking for “straight” video art (even if it is edited on a computer) or still images rendered on computers and other material that refers to more “traditional” media forms. Forms were the traditional tools have been replaced with computers and software.

Curators for the biennial are Anna Kindvall and Lars Gustav Midbxe.

Practical: You can submit with our online form or download the application form as PDF-file. You have to use one of these two forms to submit to our call. This can be found on this address. NOTE: Please do NOT send documentation material as attachments via e-mail. Put your material online and send us the download URL or ftp address, or send us a CD or similar in the mail. Do NOT send 8 pages CVs and only complement with enclosures if it is necessary. Please read the form and follow the guidelines. We receive a large amount of proposals and all of them are reviewed closely. To be able to do this we ask you to follow the structure in the application form and the topics mentioned above.

Financial: Due to a limited budget we will encourage everyone submitting material to look for possibilities for local funding to help cover costs for transport, travel and rent of technical equipment. This is not a requirement but a request; external funding can help us during the financial planning. The quality of the artwork will always be the determining element.

Electrohype covers all expenses, within reasonable limits, and also pays an artist honorarium to participating artists. Electrohype does not support development and production of unfinished artworks.

In previous exhibitions we have managed to keep a high level both in artistic content and exhibition design, even on a modest budget. It is therefore very important for us to avoid unpleasant surprises, so please keep this in mind when filling out the various posts in the form, especially when it comes to technical requirements, transport weight etc.
