Open ph.d. position

We currently have an opening for a ph.d.-student in our lab in a project investigating synaesthesia and expertise. The position is a three year position at Aalborg University, with strong collaborations in Iceland, China, and the US.

For more information and to apply please see (advertisement here).

The application deadline has been extended to February 1st 2017.

Hearts & Minds

Thanks to everyone who attended my lecture on The Brain, Vision, and Synesthesia at the Hearts & Minds festival this friday at Aarhus University. It was great talking about the brain and some of our research on synesthesia to all of you and I hope you had a great evening at Folkeuinversitetet.

I mentioned some links to some of you, and thought I would post the links here for your convenience. The first is the link to one of my colleagues from Russia who is gathering data on the dress phenomenon. You can participate in his questionnaire here: http://chetvericov.ru/tests/thedress/quiz.html

Secondly, you can find our synesthesia project on the following webpage: https://synesthesiaproject.wordpress.com/

Components of Attention in Grapheme-Color Synesthesia: A Modeling Approach

The first of our studies on synaesthesia is now available online for free.

ITVA

A recent study published online in PLoS ONE by Ásgeirsson et al. (2015) use TVA to analyse what attentional components are modulated by stimulus congruency in colour-grapheme synaesthesia. The authors report that processing speed is affected by stimulus congruency. Surprisingly, several TVA parameters such as the threshold for visual perception as well as attentional selectivity remain un affected by a manipulation of congruency. The authors argue that as well as yielding a more detailed understanding of how synaesthesia interact with cognitive components like attention.

The study is freely available online at http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0134456

Components of Attention Modulated by Temporal Expectation

ITVA

In a new study published in Journal of Experimental Psychology: Learning, Memory, and Cognition, Sørensen et al. (2014) investigate the effects of temporal expectation and how it modulate attentional TVA parameters. They demonstrate that the temporal expectancy paradigm modulate visual short-term memory, possibly through a phasic modulation of observer arousal akin to a hypothesis proposed by Easterbrook (1959). Sørensen et al. also present a novel analysis using the standard deviation of the attentional weights as a measure of how evenly an observer distribute their attentional resources. Hereby, it is possible to measure the scope of attentional focus in addition to the traditional TVA parameters.

Student help wanted

Form the 1st of January I am starting to work on my ph.d. project on the nature of the capacity limitations of visual short-term memory. Basically, I will continue the work started in my master thesis and expand on the basic ideas briefly described in that project.

I would like to have student assistants (this is usually on volunteer basis) on the project, so if you are interested please contact me – my own interests where originally sparked by being a student helper on ph.d. projects by Morten Overgaard and Søren Kyllingsbæk.

The main areas I will be working on – at least from my current perspective – will be the following:

  • Visual Short-Term Memory
  • Visual Long-Term Memory
  • Memory Capacity
  • Visual Representations and Categories
  • Consciousness
  • Early processes in TVA

If you find any of these areas interesting and would like to assist in a research project, feel free to contact me – I am interested in students on all levels – whether you are working on your master thesis or you are a first year student.

During this month I will prepare for the project startup so that I can be ready for the real startup in January – this project will be running over the next three years and you can choose to join in on different parts of it if you like.
