Three experiments are described in which participants were asked to look for target objects in cluttered displays. To help participants find the targets, cues were presented next to the target (and pointing / looking at the target). The results showed that cues that had a clear outline (e.g., arrows, hands) helped finding the target, while cues that did not have a clear outline (e.g., gazing eyes) did not speed up finding the target, independent of whether the cue was biologically relevant (social or symbolic) or not. Cues that are easy to find themselves have the strongest effects on finding a search target. These results confirm <a href="http://link.springer.com/article/10.1007/s00426-015-0733-2">earlier findings</a> in an cue interference paradigm.Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-86654146565009124582017-01-21T09:33:00.001-08:002017-01-21T09:33:19.380-08:00Dissertation studies now looking for volunteersMost dissertation projects have now started data collection, so if you are willing to take part, please get in touch. The various studies involve reporting body satisfaction for your own body or other people's bodies (Shannon), guessing whether eyes belong to violent on non-violent offenders (Kate), guessing numbers, such as what percentage of people attend university in the UK (Matt), choosing which program to treat alcohol dependency works best (Harman), identifying perpetrators from line-ups (Joan), deciding on the basis of descriptions of people whether you would give them a job or drink tea with them (Laura), and deciding whether you see a female or a male person in a photograph, while ignoring words (Charmaine).Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-26773675233296968952017-01-21T09:22:00.004-08:002017-01-21T09:22:48.757-08:00Work on social attention in real world search presented at the BOMG meeting in CardiffLast Wednesday <a href="http://staff.lincoln.ac.uk/tlhodgson">Tim Hodgson</a> and I attended the meeting of the British Oculomotor Group (BOMG) in Cardiff. All aspects of eye movements were discussed at the meeting, including brain imaging of regions involved in the planning and control of eye movements (<a href="http://www.uni-regensburg.de/psychologie-paedagogik-sport/psychologie-greenlee/team/greenlee/">Greenlee</a>), the training of vergence eye movements (<a href="http://iris.dr2.cnrs.fr/spip.php?article99">Kapoula</a>), nystagmus (various talks) and reading scrolling text (<a href="https://pure.royalholloway.ac.uk/portal/en/persons/hannah-harvey(be6d5ec6-11f9-442f-8dd2-990329093395).html">Harvey</a>). In my own talk, I presented recent work, supported by an <a href="http://eps.ac.uk/">EPS</a> grant. In the study, we examined whether participants find objects placed in different rooms more quickly when cues (gazing eyes, a pointing hand, or an arrow) indicated the location of the object. This was indeed the case, but the effect of the cue did not depend on the type of cue.Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-16388276904037899752017-01-21T09:15:00.002-08:002017-01-21T09:15:43.211-08:00Flora presents summer scientist work at AVA meetingOn Monday 19 December, my PhD student, Flora Ioannidou presented her first study in the context of her PhD at the <a href="http://www.theava.net/meetings/qmul2016.html">AVA meeting</a> at Queen Mary University of London. In her poster, she presented the results from a study conducted at the <a href="https://summerscientist.blogs.lincoln.ac.uk/">summer scientist event</a>. Children were asked to sit at a computer and to search for a target object in screens full of objects. On some of the trials, cues were placed near the target object to examine whether such cues help children to find the target. The results showed that hand and arrow cues helped in finding the target, particularly in young children, but that eyes did not have such effects.Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-51225128836557076162016-10-05T13:03:00.002-07:002016-10-05T13:03:38.423-07:00Study on safety sentiments in Lincoln completedIn a recently completed MSc (Forensic psychology) dissertation project, Freya has examined how safe students feel when seeing images, while using an eye tracker to examine where people look when making such judgements. The study showed that images of Egham (Royal Holloway University) were rated as safer than images of Lincoln, and that these higher safety ratings were related to ratings of maintenance. Images of night scenes were rated lower on safety. While participants rated images for safety, they inspected street-lights to a larger extent than while they judged images for maintenance. Female participants reported higher levels of unsafe feelings compared to male participants, both in their overall ratings, as well as in their ratings of the different images. The results suggest that the council can improve safety sentiments by aiming for higher levels of maintenance and by better street lighting.<br />

Plans are made to use mouse tracking while people guess whether pairs of eyes are from violent or non-violent offenders and to ask people to rate their body satisfaction. Volunteers will be needed soon, so if you are interested in taking part, please get in touch with the contact details on <a href="http://staff.lincoln.ac.uk/fhermens">my staff page</a>.Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-69742289914761674692016-10-05T12:50:00.000-07:002016-10-05T12:50:09.277-07:00Paper published on the central bias in day-to-day viewingOur paper on the central bias in day-to-day viewing is now available online, at <a href="https://bop.unibe.ch/index.php/JEMR/article/view/2787">this address</a>. In the study, participants navigated around the building, made tea, or sorted cards while wearing a mobile eye tracker (Tobii 2 glasses). Analysis of the data showed that people tended to shift their gaze by moving their heads so that the recorded gaze position was held in the middle of the head-centred video image. Moreover, this bias towards the centre was not influenced by the task. We propose that, in the absence of dedicated mobile eye tracking software, spy-glasses can provide a feasible means of guessing where people look in day-to-day tasks, by assuming that they mostly gaze at the central region of the head-centred image.Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-11609790706870959012016-10-05T12:45:00.001-07:002016-10-05T12:45:31.107-07:00Lights nightOn September the 30th, the lab had two exhibitions at the <a href="http://www.lincoln.ac.uk/home/campuslife/whatson/eventsconferences/lightsnights.html">Lights Night public engagement event</a>. In the first exhibition, participants were invited to walk the stairs wearing the Tobii 2 glasses mobile eye tracker, either while walking normally, or while writing a text on their phone. Play-back of the recorded eye movements showed that participants shifted their focus almost completely towards their phone while texting, showing that it is not safe to text and walk.<br />
<br />
In the second exhibition, participants were invited to guess the calorie, saturated fat, sugar or sodium contents of a series of foods. Before some of the guesses, participants were asked to guess whether the amount was lower or higher than a given value. Previous work has shown that participants tend to be biased by these given amounts, an effect called anchoring. The demonstration also confirmed the 'health halo' effect, in which foods that are considered to be healthy are thought to be lower in calorie contents.<br />
<br />
If you would like to give the second demonstration a try: the software can be found <a href="https://drive.google.com/open?id=0ByYklLyijBGIYWN0a2NWT000Wmc">here</a>. To run it on your PC, first install Opensesame from <a href="https://github.com/smathot/OpenSesame/releases/download/release%2F2.9.7/opensesame_2.9.7-win32-1.exe">this link</a> (version 2.9 is needed; it won't work on version 3.0).<br />

Participants were wearing the Tobii 2 glasses system and asked to walk up three different sets of stairs. When walking up one of the stairs, they were asked to create a text message on their phone.<br />
<br />
The data are still being analysed, but a first glance at the eye movement data suggests that while using a phone, participants are hardly looking at the stairs and only focus on the phone.Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-44489043511541603832015-12-15T02:33:00.003-08:002015-12-15T02:33:33.031-08:00Presentation at the Eating disorders, social media and digital technology workshop<br />I presented Leanne Caie's (University of Aberdeen) and Hannah Russell's (University of Lincoln) studies at the Eating disorders, social media and digital technology workshop in Lincoln.<br />

With a fairly large group, we attended the 2015 ECVP (visual perception) conference in Liverpool. The conference started with a lecture inside a church (acoustics were not optimal), and on the next day a very interesting session on eye tracking social interaction. I had my own poster on the influence of social cues when they are viewed (initially) outside of fixation, and my colleagues from Aberdeen (Bert Timmermans) and Belgrade (Suncica Zdravkovic) presented data from joint projects on dual gaze tracking (Timmermans) and lightness influences on eye gaze (Zdravkovic). The sessions were well attended, particularly in the first days of the conference. On the way back we had a long look at the Peak district (meaning: traffic jam). <br />

The group that I am supervising this semester will look at how well people guess the calorie contents of foods and how this related to how confident they are about their guess.<br />
<br />
If you are on campus you may be asked to take part. The students will go around with their laptops and Android devices (thanks to http://osdoc.cogsci.nl/) and ask for your input. Don't be shy! We will store all information anonymously, so don't worry about not being good at the task. The task should take around 5 minutes.<br />

Before explaining what it is all about, why not take part in our study?<br />
<br />
Your tasks will be to make tea, sort a deck of cards and to walk around the building, while you wear our latest gadget (very similar to a pair of glasses).<br />
<br />
The only requirement for taking part is that you do not wear glasses already (and it would come in handy if you are in the Lincoln area).<br />
<br />
Interested?<br />
Simply contact me:<br />

The new academic year has started, with eight students doing their dissertation projects with me. Everyone is now on track. The following projects will be taking place:<br />
<br />
* Ebony will be using eye tracking to examine attitudes towards offenders.<br />
* Hannah will use eye tracking to examine the link with eating behaviour.<br />
* Julija will use eye tracking to examine how people reach decisions.<br />
* Laura will use mouse tracking to study implicit attitudes towards domestic abuse.<br />
* Omari will look at how highlighting influences decisions<br />
* Shaquille will be examining how attire influences trust and eye movements<br />
* Oliver will examine eye movements in a video link<br />
* Amber will study how advance information about one of the actors influences eye movements. <br />
<br />
They will all need participants, so if you are in the Lincoln area, please do not hesitate to get in touch!Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-36240471072878923202015-08-03T09:03:00.000-07:002015-08-03T09:03:29.479-07:00Summer Scientist completed<div>

The task was to decide for a predefined target (arrows, eyes, or hands), whether they were pointing or looking left or right. Participants were asked to use the computer mouse and reveal the target stimulus (together with a distractor) by clicking on a start button in the bottom of the screen. They were then asked to move the mouse as quickly as possible to the button in the top of the screen indicating the direction of the target (see Figure 1).</div>

<br />
For our task, we found that the youngest children had little experience using the computer mouse, suggesting we should use a touch screen in future studies, because every child indicated having used a tablet PC.<br />
<br />
This is reflected in Figure 2, showing what number of participants completed the experiment, consisting of a total of 53 decisions (including five to practice).<br />
<br />
We also found that accuracy of the response was reduced only for the youngest children, whereas response times kept on improving with age (Figure 3).<br />
<br />
After this initial analysis, the focus will now be on examining how the different types of cues (hands, arrows, and eyes) influence response times, accuracy and mouse trajectories.<br />

For the children, there was the visual search task on the laptop. The adults were shown examples of our eye movement research. There were also several enquiries about studying at the University of Lincoln.<br />

I will present my study in which I examined whether grouping the attributes of each alternative (by means of a bounding box) in a risky choice leads to more eye movements within a choice (no) and a stronger influence of the expected value difference between the choices (no).<br />

In this event, children can take part in our studies. In my study, I will look at how two cues of direction (eyes gazing and hands pointing) compete for attention.<br />
<br />
Instead of using <a href="http://www.mousetracker.org/">Mouse Tracker</a> I will use <a href="http://eointravers.github.io/blog/2014/03/os-mousetracking/">mouse tracking in OpenSesame</a> for the simple reason that while OpenSesame could be installed on the lab computers, installing Mousetracker could not (no admin permissions). Using <a href="http://osdoc.cogsci.nl/">OpenSesame</a> I found that it was easier to present to images simultaneously, and change the feedback given to the participant. Many thanks to <a href="http://eointravers.github.io/">Eoin Travers</a> for sharing the mouse tracking script!Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-17959042698525021902015-06-12T08:05:00.001-07:002015-06-12T08:05:20.709-07:00Paper in Visual Cognition onlineMy paper in Visual Cognition is now online (at http://www.tandfonline.com/doi/full/10.1080/13506285.2015.1042539).

The paper shows that fixation instruction can influence response times in a gaze cueing paradigm. So unless you would like to find a pattern of results consistent with inhibition of return, it is important to take measures to ensure participants maintain fixation.Froukehttp://www.blogger.com/profile/03978563470566800414noreply@blogger.com0tag:blogger.com,1999:blog-4885330868067124861.post-29941033208160369792015-06-12T07:56:00.002-07:002015-06-12T08:29:01.436-07:00First Lincoln data accepted for publicationMy first bit of data from Lincoln that has been accepted for publication will appear in a paper together with <a href="http://lepns.psihologija.edu.rs/suncica-zdravkovic/?lang=en">Sunčica Zdravković</a>. In the article, we show that observers avoid fixation darker regions in images due to (simulated) shadows influence observers' eye movements, in agreement with an optimal sampling strategy.<br />
