Components of Attention Modulated by Temporal Expectation

Originally posted on 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.

CCN moves to a new location on the Aalborg campus

During the summer Centre for Cognitive Neuroscience (CCN) will move to Kroghstræde 6 along with the new facilities for behavioural studies at Aalborg University: Experimental Psychology Laboratory. Here there will be four rooms for controlled behavioural studies including one multi room for larger setups, and training of students in experimental and behavioural methods in psychology. 

The new lab will ensure that students on the neuropsychology program (along with BA students who have a special interest in behavioural neuroscience) can participate in ongoing research projects at CCN. Students will also be able to suggest individual projects within topics such as memory, attention, perception, and consciousness. Here we will be able to provide individual supervision and training for a number of projects each semester independent of the scheduled classes.


The Disappearing Hand

The first prize at the 8th Annual Best Illusion of the Year Contest at VSS in 2012 went to a demonstration by Roger Newport, Helen Gilpin and Catherine Preston called the disappearing hand trick.

This demonstration made me think of some beautiful experiments conducted in Copenhagen by Torsten Ingemann Nielsen in 1963 called the alien hand experiment. Here an observer also lets visual input override proprioceptive information, as an experimentor through the use of mirrors manipulate the visual feedback of the observer (see fig 1 in Gallagher & Sørensen 2006).

Flashed face distortion effect

This interesting demonstration won the second prize at the 8th Annual Best Illusion
of the Year Contest at VSS this year. It was presented by Matthew Thompson, and who recently published a paper with his colleagues describing the effect in Perception (Tangen, Murphy & Thompson, 2011).

You can also read the story of the discovery of the flashed face distortion effect in the UQ Psyc blog.

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.

Course update

I am working on the two courses in consciousness for the fall semester today, so hopefully I will have some updates on these courses late afternoon or early evening today. I plan to update information on literature for the course, the type of exam the course will have, and probably also a bit information about the form of the course.

Course Update

It seems that I will teach several courses in the fall semester and I am currently planning several different courses.

I will probably teach two courses at the University of Copenhagen and furthermore I plan to teach one or two courses at Folkeuniversitetet (University Extension). The two courses at the University of Copenhagen will be one on the bachelor level “Introduction to Consciousness Studies” and the second will be on the masters level and has the following working title “Consciousness: a Challenge to Science“, both courses will be taught in English. Which courses I will teach at Folkeuniversitetet is not yet decided, but i will write an update as soon as I have one on these courses.

Introduction to Consciousness Studies, is thought of as a general introduction to the field of consciousness research ranging from philosophy of mind to neuroscience. Teaching will probably be in the form of lectures on the basis of a textbook on the subject of consciousness research, currently I am considering a textbook by Susan Blackmore.

Consciousness: a Challenge to Science, will be a more advanced course that probably will be arranged as a workshop on the basis of a collection of different central and classical articles within the field of consciousness research. This course is not thought of as a purely methodological approach, which the title could hint, but also delve into the problems of the definition of consciousness, epistemology, and ontology.
