Validating Habitual and Goal-Directed Decision-Making Performance Online in Healthy Older Adults

2021

Everyday decision-making is supported by a dual-system of control comprised of parallel goal-directed and habitual systems. Over the past decade, the two-stage Markov decision task has become popularized for its ability to dissociate between goal-directed and habitual decision-making. While a handful of studies have implemented decision-making tasks online, only one study has validated the task by comparing in-person and web-based performance on the two-stage task in children and young adults. To date, no study has validated the dissociation of goal-directed and habitual behaviors in older adults online. Here, we implemented and validated a web-based version of the two-stage Markov task usi…

Tasks that suit the learning of L2 English vocabulary in the Finnish middle school : teachers' and students' perspectives

2013

Tiivistelmä – Abstract Tutkielman tarkoituksena oli selvittää yläkoulun oppilaiden ja opettajien mielipiteitä sanaston oppimiseen suunnatuista tehtävistä; millaiset tehtävät heidän mielestään sopivat sanaston oppimiseen yläkoulussa. Samalla selvitettiin sanaston oppimista koulun ulkopuolella sekä sanaston oppimiseen käytettyä aikaa. Oppilaiden ja opettajien mielipiteitä verrattiin toisiinsa. Tutkimus toteutettiin Tampereella vuonna 2010. Osallistujina olivat kolme englannin opettajaa ja heidän luokkansa, yksi kutakin luokka-astetta, yhteensä 52 oppilasta. Kaikki osallistujat vastasivat kyselyyn, johon oli ennalta valittu oppikirjoista tietyt tehtävät arvioitaviksi tietyin kriteerein. Lisäks…

Multi-Scale Modelling of Segmentation : Effect of Music Training and Experimental Task

2016

While listening to music, people, often unwittingly, break down musical pieces into constituent chunks such as verses and choruses. Music segmentation studies have suggested that some consensus regarding boundary perception exists, despite individual differences. However, neither the effects of experimental task (i.e. realtime vs annotated segmentation), nor of musicianship on boundary perception are clear. Our study assesses musicianship effects and differences between segmentation tasks. We conducted a real-time task experiment to collect segmentations by musicians and non-musicians from 9 musical pieces; in a second experiment on non-realtime segmentation, musicians indicated boundaries …

The Dynamic Relationship between Response Processes and Self-Regulation in Critical Thinking Assessments

2021

Our aim was to explore higher education students’ response and self-regulatory processes plus the relationship between these, as evidenced in two types of performance-based critical thinking tasks included in the Collegiate Learning Assessment (CLA+) International instrument. The data collection consisted of 20 cognitive laboratories. The data were analyzed using a qualitative approach. The tasks were found to trigger different response and self-regulatory processes. Overall, the performance task evoked more holistic processes than the selected-response questions, in which students’ processes were more question-oriented. The results also indicated the entanglement of students’ response and …

A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens

2017

The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…

Space-by-Time Modular Decomposition Effectively Describes Whole-Body Muscle Activity During Upright Reaching in Various Directions

2017

The modular control hypothesis suggests that motor commands are built from precoded modules whose specific combined recruitment can allow the performance of virtually any motor task. Despite considerable experimental support, this hypothesis remains tentative as classical findings of reduced dimensionality in muscle activity may also result from other constraints (biomechanical couplings, data averaging or low dimensionality of motor tasks). Here we assessed the effectiveness of modularity in describing muscle activity in a comprehensive experiment comprising 72 distinct point-to-point whole-body movements during which the activity of 30 muscles was recorded. To identify invariant modules o…

Uzdevumos balstīta prezentācijas prasmju pilnveide augstskolā

2017

Mūsdienās prezentēšanas prasmes ir kļuvušas par aktuālu tematu. Prasme prezentēt auditorijas priekšā augstskolās ietekmē ne tikai personīgo izaugsmi, bet arī karjeru nākotnē. Lai sniegtu pārliecinošu prezentāciju, prezentētājam būtu jāzin pārliecināšanas paņēmieni. Maģistra darba mērķis bija izpētīt prezentācijas prasmju pilnveidi augstkolās, koncentrējoties uz uzdevumiem, kas aptver konkrētus pārliecināšanas paņēmienus. Pētījuma rezultāti parāda, ka studenti apzinās konkrētu pārliecināšanas paņēmienu nozīmi, bet ir piesardzīgi to lietojumā sniedzot prezentāciju, kas var tikt pamatots ar zemu angļu valodas prasmi.

Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users

2018

Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…

How to get things done in social virtual reality : A study of team cohesion in social virtual reality–enabled teams

2022

Social virtual reality (SVR) enables teams to operate in a virtual environment that simulates and enhances real-world interactions. However, there is an absence of empirical analysis of how SVR can affect the performance of virtual teams. This paper documents how SVR affects the formation of team cohesion (i.e., task cohesion and social cohesion), which is a critical success factor for team performance. To address this gap in the research, we conducted a qualitative study by interviewing 20 members from virtual teams assigned to perform a challenging collaborative task in SVR. As a contribution, our study identifies five primary affordances and 11 sub-affordances for team cohesion in SVR. W…
