The focus and timing of gaze matters : Investigating collaborative knowledge construction in a simulation-based environment by combined video and eye…

2022

Although eye tracking has been successfully used in science education research, exploiting its potential in collaborative knowledge construction has remained sporadic. This article presents a novel approach for studying collaborative knowledge construction in a simulation-based environment by combining both the spatial and temporal dimensions of eye-tracking data with video data. For this purpose, we have investigated two undergraduate physics student pairs solving an electrostatics problem in a simulation-based environment via Zoom. The analysis of the video data of the students’ conversations focused on the different collaborative knowledge construction levels (new idea, explication, eval…

All Eyes on Me : Behaving as Soloist in Duo Performances Leads to Increased Body Movements and Attracts Observers’ Visual Attention

2020

Duo musicians exhibit a broad variety of bodily gestures, but it is unclear how soloists’ and accompanists’ movements differ and to what extent they attract observers’ visual attention. In Experiment 1, seven musical duos’ body movements were tracked while they performed two pieces in two different conditions. In a congruent condition, soloist and accompanist behaved according to their expected musical roles; in an incongruent condition, the soloist behaved as accompanist and vice versa. Results revealed that behaving as soloist, regardless of the condition, led to more, smoother, and faster head and shoulder movements over a larger area than behaving as accompanist. Moreover, accompanists …

Successful approaches to mental practice : A case study of four pianists

2019

Musicians often use mental practice for enhancing performance, but individuals may have different preferences and skills in their characteristic, individually successful ways of carrying out such practice. In this study, we focus on the approaches to mental practice of four pianists who, according to the ratings of a panel of expert judges, showed outstanding improvement in their performances following their mental practice of a new piece in at least one of the two conditions: silent reading of the score or reading the score while simultaneously listening to the music. The four pianists’ approaches to mental practice were studied through self-reports in post-task interviews that were compar…

What comes first: Combining motion capture and eye tracking data to study the order of articulators in constructed action in sign language narratives

2020

We use synchronized 120 fps motion capture and 50 fps eye tracking data from two native signers to investigate the temporal order in which the dominant hand, the head, the chest and the eyes start producing overt constructed action from regular narration in seven short Finnish Sign Language stories. From the material, we derive a sample of ten instances of regular narration to overt constructed action transfers in ELAN which we then further process and analyze in Matlab. The results indicate that the temporal order of articulators shows both contextual and individual variation but that there are also repeated patterns which are similar across all the analyzed sequences and signers. Most not…

Silmänliiketutkimus - Fysiologinen näköjärjestelmä ja katseenseurannan tekniikat

2010

 Kotilainen, Ilkka Antti Silmänliiketutkimus fysiologinen näköjärjestelmä ja katseenseurannan tekniikat / Ilkka Kotilainen Jyväskylä: Jyväskylän yliopisto, 2010 37 s. Kandidaatintutkielma Tässä kirjallisuuskatsauksena suoritetussa kandidaatintutkielmassa tarkastellaan silmänliiketutkimuksessa käytettäviä neljää katseenseurannan tekniikkaa: elektrookulografiaa (engl. ElectroOculoGraphy, EOG), kovakalvolle sijoitettavaa piilolinssiä/induktiokäämiä (engl. scleral contact lens/search coil), valokuvaokulografiaa (engl. PhotoOculoGraphy, POG) tai videookulografiaa (engl. VideoOculoGraphy, VOG) ja videopohjaista pupillin ja sarveiskalvoheijasteen yhdistelmää (engl. video based combined pupil and c…

Visual cues improve students’ understanding of divergence and curl: Evidence from eye movements during reading and problem solving

2019

The coordination of multiple external representations is important for learning, but yet a difficult task for students, requiring instructional support. The subject in this study covers a typical relation in physics between abstract mathematical equations (definitions of divergence and curl) and a visual representation (vector field plot). To support the connection across both representations, two instructions with written explanations, equations, and visual representations (differing only in the presence of visual cues) were designed and their impact on students’ performance was tested. We captured students’ eye movements while they processed the written instruction and solved subsequent c…

Toiseuden lumo : eksoottisuus ja eroottisuus revyyteatteri Punaisen Myllyn esityksissä

2014

Tutkin pro gradu -tutkielmassani millaista eksotisointia etnisyydestä ja naiseudesta luotiin suomalaisen revyyteatteri Punaisen Myllyn (1946-1967) ohjelmistossa esitysten visuaalisten yksityiskohtien (puvustus, lavastus, rekvisiitta, ruumiinkieli) avulla. Lähestyn tutkimusaihettani ensisijaisesti valokuva-aineiston pohjalta kiinnittäen huomiota siihen, kuinka puvustuksen, lavastuksen ja rekvisiitan avulla luotiin ja vahvistettiin eksoottista ja eroottista kuvastoa. Aihepiiristä (revyyteatteri, kabaree, burleski) on tehty viimeisten viiden vuoden aikana muutamia opinnäytetöitä, ja revyy- ja kabareemaailmasta, eksotismista ja visuaalisuudesta on yksittäin puolestaan kirjoitettu paljonkin. Sit…

The relationship between skin conductance and eye contact of spouses in couple therapy

2017

Katsekontaktin ja ihon sähkönjohtavuuden välistä yhteyttä on tutkittu aiemminkin, mutta tutkimusta ei ole tehty monitoimijaisessa terapiatilanteessa. Tämän tutkimuksen tarkoituksena oli tarkastella ihon sähkönjohtavuuden ja katsekontaktin välistä yhteyttä pariterapiassa pariskunnan välisen synkronian kautta, ja lisäksi selvittää, kuinka ihon sähkönjohtavuus muuttuu katsekontaktin eri hetkinä: ennen kuin katsekontakti alkaa, sen alkamishetkellä, ja alkamishetken jälkeen. Oletuksena oli, että ihon sähkönjohtavuuden vasteet nousevat katsekontaktin alkuhetkellä. Lisäksi tarkasteltiin, onko miehillä ja naisilla eroa ihon sähkönjohtavuuden vasteissa. Tutkimuksen otos koostui 11 pariskunnasta, joi…

Mentalizing eye contact with a face on a video : Gaze direction does not influence autonomic arousal

2018

Recent research has revealed enhanced autonomic and subjective responses to eye contact only when perceiving another live person. However, these enhanced responses to eye contact are abolished if the viewer believes that the other person is not able to look back at the viewer. We purported to investigate whether this “genuine” eye contact effect can be reproduced with pre‐recorded videos of stimulus persons. Autonomic responses, gaze behavior, and subjective self‐assessments were measured while participants viewed pre‐recorded video persons with direct or averted gaze, imagined that the video person was real, and mentalized that the person could see them or not. Pre‐recorded videos did not …
