The Humanities Lab a partner in an AHRC Skills development scheme on Multilingualism

Azra Padjan — Wed, 22 Feb 2012 10:29:09 +0000

The Humanities Lab has become a partner in an AHRC Skills development scheme on Multilingualism (Skills development for language research and teaching in a multilingual world), funded by the Arts and Humanities Research Council, UK (main applicants Drs Seyfeddinipur, Lüpke, Iwasaki; partners Gullberg, Lund and Deuchar, Bangor).

The enterprise connects the Humanities Lab to the School of Oriental and African Studies (SOAS http://www.soas.ac.uk/) at University College London and to the ESRC Centre for Bilingualism Studies at Bangor University. Lund and Bangor provide methodological training opportunities for junior and senior scholars and SOAS opens opportunities for access to non-European mutilingual field sites.

ET-seminar 2012-02-10: Damon Tutunjian about his plans to record reading data on implicit agent activation in adjectival vs. verbal passives.

kenneth — Fri, 10 Feb 2012 11:42:24 +0000

At todays ET-seminar, Damon Tutunjian presented an upcoming experiment for using eye-tracking to study implicit agent activation in adjectival vs. verbal passives. Understanding the purpose of this study requires an example, and Damon gave us the following:

(1) a. The new technology was very efficient to get ahead of the competitors.

b. The new technology was very advanced to get ahead of the competitors.

c. The new technology was quickly advanced by the scientists to get ahead of the competitors.

d. The new technology was quickly advanced to get ahead of the competitors.

In the passive sentence (d), there is an un-mentioned agent (the one advancing), and this implicit agent is the one under study. We had an intense discussion about the assumptions on the language model, in particular how it activates the agent, and whether this activation involves only grammatical, or only lexical, or perhaps even a conceptual meaning, i.e. does the sentence alone tell us about the advancing person. How much of the agent information is activated?

This topic requires a complex experimental design, which also puts strains on the data analysis. Single sentence reading is an established paradigm, however, with its own set of dependent variables. The second part of the discussion focussed on the set of reading measures (first fixation duration etc.) that Damon plans to used, and what type of statistical tests can deal with the design.

Next Friday, there will be no ET seminar, because the eye-tracking group is busy giving the international LETA crash course in eye-tracking methodology. In two weeks time, on Friday the 24th, Richard Dewhurst will lead a discussion on how to write excellent scientific papers that get lots of citations in the eye-tracking and vision community.

ET-seminar 2012-02-03: Kerstin Gidlöf about how stages in decision making can be seen in eye movement data

kenneth — Fri, 03 Feb 2012 11:27:46 +0000

At today’s ET-seminar, we discussed how to detect cognitive states such as ’search’, ‘evaluation’ and ‘decision’ in eye-movement data. Although Kerstin examines decisions in supermarkets, the underlying question about cognitive processes is the same for all search tasks: radiology, psycholinguistics, visual search etc: it is clear that even if we see changes in eye movement behaviour over a task, it is not clear how we build a link to the cognitive processes that allows us to say when stages start and end? Should the division be based on theory (decision making theory, in Kerstins case), or on data alone?

Kerstin chose to start from Russo and Leclerc’s suggestion that the border between the orienting phase and the decision phase is when the first refixation (redwell) is made, but changed it to when the participant first looks at the item to be selected (bought). This change moves the border to later in the process, and makes data values such as dwell time and redwells between between phases more different (stronger significance values). This is still a theory-based division, but it appears to be more exact than that of Russo and Leclerc.

Many questions still remain. Are there only three stages, for instance? Could orientation, decision and evaluation be interleaved in short spurts as consumers work their way through a pasta shelf; which would speak in favor of a data-driven analysis.

Next Friday, Damon Tutunjian presents his plans to record reading data on implicit agent activation in adjectival vs. verbal passives.

ET-seminar 2012-01-27: Ignace Hooge about search of small objects near borders

kenneth — Fri, 27 Jan 2012 11:14:18 +0000

Today Ignace Hooge talked about visual search for specific, known targets - such as searching for a contact lens on the floor, a particular village in a map, or a tumor in a mammography image. It is known that the border of the object may masked by neighbouring borders, degrading the perceived contrast around the object so it becomes effectively invisible. According to the literature on visual crowding and focal and ambient search, this should make fixation durations longer and saccade amplitudes shorter when participants search close to the a border, but Ignaces data show the opposite. We had a long discussion why participants search so inefficiently in these tasks.

This is one of the studies Ignace will be working with here. The three others are: 1) a systematic table of under what noise and sampling frequencies event detection algorithms break down, 2) investigating whether the small glissade at the end of saccades are real eye movements or artifacts of the measurement equipment, and 3) study the effect on data quality of using another luminosity during calibration compared to the actual recording.

Next Friday, we will discuss Kerstin Gidlöfs paper about phases in the decision process, and how that can be measured using eye movements. The full program for the eye-tracking seminar can be found at http://wiki.humlab.lu.se/dokuwiki/doku.php?id=public:eyetracking_seminar

ET seminar 2012-01-20: Kick-off, planning and form

kenneth — Fri, 20 Jan 2012 11:50:05 +0000

At today’s seminar, we planned the spring semester. The interest in seminar slots promises that this can be another productive year in the eye-tracking group. There are still a few slots left, however. Contact us if you run eye-tracking projects and would like to present at the seminar.

The second half of the seminar focussed on improving the format. The eye-tracking seminar differs from many other seminars by its strong focus on improving the research of the participants. Reading and commenting on experiments and draft papers so that they can be published in the best journals is the key goal. We therefore decided on new feedback formats that will be tested during the next few seminars. Details are on the seminar list: http://wiki.humlab.lu.se/dokuwiki/doku.php?id=public:eyetracking_seminar

At the next seminar, Jan 27th, Prof Ignace Hooge of Utrecht, a psychologist with an impressive track record in eye movement research, who is visiting the eye-tracking group for two months, will present himself and the work he will make here.

ET-seminar 2011-12-16: Choice blindness and implicit measures of detection

kenneth — Fri, 16 Dec 2011 11:27:21 +0000

At today’s seminar Philip Pärnamets presented his study that uses eye movements to investigate choice blindness. In this paradigm, participants are tricked into thinking they selected something else than what they actually selected. Although this effect is considered stable across many tasks - people do get fooled, and do not remember what they actually selected - little is known on the precise psychological processes underpinning the effect.

Philip showed faces, and asked which is more attractive, and then asked participants to motivate their choice (while sometimes showing the wrong face). Discussion focussed on experimental design; such as the uneven number of trials typical of this paradigm, and method; for instance whether it is feasible to investigate pupil dilation over time with similar process measures as used for EEG and ERP data. In many studies, the relation between theory, including spatial and visual cognition, and eye-movement measures need careful thought, and much of the discussion focussed on this central issue.

The full program for eye-tracking seminars can be found http://wiki.humlab.lu.se/dokuwiki/doku.php?id=public:eyetracking_seminar.

The ET seminar takes a break over holidays. Next Friday (Jan 20th) our guest professor Ignace Hooge from Utrecht will present himself and the collaboration we have started with him.

———————————-

At the ET-seminar, which was established in 2001, researchers active in eye tracking discuss planned experiments, data analysis of eye movement data, drafts of papers and book chapters, conferences we organize etc, but we also invite international speakers and guests in our network. The ET-seminar in Lund is also availble via Skype (lund_et_seminar).
