You can’t get rid of me that easily.....

I am very happy to announce that I shall be continuing my research for at least another year. I have been accepted for a post-doctoral research position in John M. Henderson’s Visual Cognition lab in the Edinburgh University Psychology department. Now I know what you’re all thinking: “I thought he was already in Edinburgh Uni”. You are correct. My current status is as a Research Associate for the Le Active Math project employed by Moray House School of Education at Edinburgh University. However, my move to Psychology will be a very fortuitous one as it will allow me to conduct my research without distraction and within a group of likeminded people.

This move to psychology has only been made possible by the uncannily well-timed move of John Henderson’s visual cognition lab from Michigan State University to Edinburgh. John and his partner Fernanda Ferreira were offered chairs in our psychology department and they were wise enough to accept. In the simple signing of a contract Edinburgh has suddenly become a hot-bed of eyetracking and visual cognition research. John, for those of you who don’t know, is one of the foremost researchers in the field of visual search, scene perception, and visual cognition in general. If you read my thesis you will find that he is one of my most cited people. His work is highly influential and I am sure that it will continue to be so from his base in Edinburgh.

John has been very encouraging of my research and interested in the theories I have been developing. As a post-doc under John I shall be continuing my research into the use of attentional cues in film to create the perception of continuity. I will also be expanding my theoretical, methodological, and writing skills to begin establishing myself as a visual cognition researcher.

Thank you, John for this opportunity.

So it looks as if you (reader) won’t be getting rid of me or this blog for a few years to come :)

Rock ‘n’ Roll Research

or “How to do an experiment in two days”.

I was contacted at the start of July by a Gustav Kuhn from Durham University. Gustav is doing some really interesting research looking at how magicians use misdirection and perceptual expectations to make you perceive something that actually isn’t there (Gustav is a highly talented magician himself. He’s available for children’s parties, corporate events, bar mitzvah’s …..). He’s done a series of eyetracking experiments to examine where people look whilst watching magic tricks. To satisfy a reviewer of one of his papers he needed to run an eyetracking study and he needed to do it fast. *Cue the Mission Impossible music*

Unfortunately, Gustav’s eyelink II system was not setup yet so he asked if he could run his study using the equipment we have here. I agreed with three small provisos:

1) the study had to take place after the 11^th July as I was at a project meeting in Germany before then;

2) I would have to run some of my own stimuli on the subjects whilst they were being eyetracked;

3) the study had to be finished by the 14^th July as I had to fly to Germany (again) to present at a conference (CCSMI, more later).

In the course of 3 days I managed to prepare two sets of stimuli for my part of the study, design and implement the experiment using the Experiment Builder software which I had never used before, test, pilot, and run 13 subjects through the experiment, and process the data so that Gustav could do his analysis. Phew! Gustav was up in Edinburgh for a day and a half and in that time we managed to get all the data we needed and, through subsequent analysis, Gustav got the result he needed to appease his reviewer. Now that’s how science should be :)

Unfortunately, the pace for my part of the experiment has slowed down somewhat. I tested two types of stimuli. The first were the videos I used in the editing memory experiment. I wanted to see which details of the videos viewers were using to detect the editing discontinuities. I also had some hypotheses about how the discontinuities would effect their eye movements (see d'Ydewalle, G., Desmet, G., & Van Rensbergen, J., 1998 for similar effects). To extract these effects I need to examine each video by hand and then perform some complex statistics on the eye movement data. Sadly this can not be done in a day L I’ll publish these results in the Editing Memory sometime soon.

The second stimuli I eyetracked were feature films. I have been desperate to get eyetracking data for films with different degrees of continuity for ages and Gustav’s urgency finally motivated me to do it. In my thesis I develop a series of hypotheses about how eye movements should be controlled by an editor in order to create the perception of continuity. This data should provide direct evidence of these techniques (if they exist) and motivate further, in depth studies. The films I eyetracked are also interesting to film theorists as they cover the most significant styles of films: Blade Runner (Continuity), Citizen Kane (Deep Focus), Koyaaniqsatsi (Non-narrative), Dancer in the dark (Dogme-esque), Eisenstein’s October (Dialectical Montage), Hulk (Digital Composition/Collage), Requiem for a Dream (Quick Cutting/MTV style), and a few more.

I’m really excited about the findings of this study and I’ll keep this blog updated as to what I find. Unfortunately, analysis of eyetracking data for long sequences of feature films is not easy and there exists no tools to assist. I’m currently developing my own methodologies, tools, and analyses to make this possible. Fingers crossed everything goes to plan and I have some interesting results to present asap.

So in conclusion, high speed experimentation is by far the most Rock ‘n’ Roll way to run experiments. Unfortunately, there is nothing Rock ‘n’ Roll about analysis. (Any suggestions on how I can make my analysis “rock” are highly appreciated)
