Interference of Illusory Contour Perception by a Distractor
2021
The visual system is capable of recognizing objects when object information is widely separated in space, as revealed by the Kanizsa-type illusory contours (ICs). Attentional involvement in perception of ICs is an important topic, and the present study examined whether and how the processing of ICs is interfered with by a distractor. Discrimination between thin and short deformations of an illusory circle was investigated in the absence or presence of a central dynamic patch, with difficulty of discrimination varied in three levels (easy, medium, and hard). Reaction time (RT) was significantly shorter in the absence compared to the presence of the distractor in the easy and medium condition…
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…
Balanced difficulty task finder: an adaptive recommendation method for learning tasks based on the concept of state of flow
2020
An adaptive task difficulty assignment method which we reckon as balanced difficulty task finder (BDTF) is proposed in this paper. The aim is to recommend tasks to a learner using a trade-off between skills of the learner and difficulty of the tasks such that the learner experiences a state of flow during the learning. Flow is a mental state that psychologists refer to when someone is completely immersed in an activity. Flow state is a multidisciplinary field of research and has been studied not only in psychology, but also neuroscience, education, sport, and games. The idea behind this paper is to try to achieve a flow state in a similar way as Elo’s chess skill rating (Glickman in Am Ches…
Age differences in the irrelevant sound effect: A serial recognition paradigm
2015
In adults, the disrupting effect of irrelevant background sounds with distinct temporalspectral variations (changing-state sounds) on short-term memory performance was found to be robust. In the present study, a verbal serial recognition task was used to investigate this so-called Irrelevant Sound Effect (ISE) in adults and 8- to 10-year-old children. An essential part of the short-term memory impairment during changing-state speech is due to interference processes (changing-state effect) which can be differentiated from the deviation effect of auditory distraction. In line with recent findings (Hughes et al., 2013), our study demonstrates that the changing-state effect is not modulated by …
