Suomi ja viro oppijan mielessä : näkökulmia taivutusmuotojen prosessointiin
2006
Kielenoppijan äidinkielen eli lähdekielen (L1) ja opittavan kielen eli kohdekielen (L2) rakenteita ja sanastoa vertaillaan usein toisiinsa, koska havaittujen erojen ja yhtäläisyyksien oletetaan olevan jossakin suhteessa kielenoppimisen kulkuun ja oppijoiden kielellisiin tuotoksiin. Oletus perustuu käytännön kokemuksiin, mutta enenevästi myös tutkimustietoon (ks. erityisesti Kaivapalu 2005). Lähde- ja kohdekielen suhteen olemuksen tutkimuksellinen määritteleminen on kuitenkin haastavampi ja mutkikkaampi tehtävä kuin pelkkä kielten ja oppijoiden puheen ja kirjoituksen vertailu. peerReviewed
Toimijuus korkeakoulutettujen suomen oppijoiden visuaalisissa narratiiveissa
2018
This socioculturally informed study explores how highly educated Finnish language learners represent their agency in visual narratives. Learners (n=59) were asked to draw two pictures of themselves as Finnish language users and provide verbal interpretations of the drawings. The aim of using visual narratives is to reach aspects such as feelings and beliefs which might be difficult to express verbally. The data were analyzed first by using visual grammar set out by Kress and van Leeuwen (2006) and secondly by content analysis. The findings suggest that learners saw Finnish language as a tool for oral communication. However, difficulties with speaking and listening appeared to restrict learn…
Development and characterisation of polymer composite materials with bio-inspired functions
2018
Promocijas darbs ir izstrādāts disertācijas veidā fizikas nozarē materiālu fizikas apakšnozarē. Pētījums tika veikts LU Materiālu mehānikas institūtā. Darbs saistīts ar aktuālu un jaunu pētījumu virzienu: bioinspirēto funkciju tālāku attīstīšanu slodzi nesošos kompozītos. Tās ir mehānisku triecienu vizuālās indikācijas un polimēru matricas vaskulārās pašdziedināšanas funkcijas. Šīs funkcijas tika nodrošinātas, izveidojot viedus slāņus un iebūvējot tos kompozītā. Pētījumā tika noskaidrotas piemērotās pārbaužu secības, attīstītas kvantitatīvas metodes un mehānisks modelis, lai novērtētu jauno funkciju efektivitāti kompozītos. Ir pierādīta funkciju augstā efektivitāte un spēja uzlabot slodzi n…
Hungarian private linguistic landscape in South-West Slovakia
2014
In the field of Linguistic Landscape research little attention has been paid to the situations where a minoritized group gives the regional majority, such as South-‐West Slovakia where Hungarians form the majority. A clear majority of public signs, also in the region with a Hungarian majority, are only in Slovak, especially in the ‘official’, public sphere. In rural communities, signs posted by private citizens can be relatively frequent, too. In the truly non-‐ commercial private sphere, minorities have autonomy in public language choice. I present the local practices and interpretations of the private linguistic landscape in two ‘Hungarian’ villages in South-‐West Slovakia in the light…
A Moldvai Csángómagyar Oktatási Program kutatása és támogatása vizuális módszerekkel
2018
A Moldvai Csángómagyar Oktatási Program kutatása és támogatása egy több éves (2016– 2021), a Finn Akadémia által támogatott projekt (projektszáma, 299133), amelynek anyaga 30 moldvai településen folyatatott, 2017–2019 között végzett terepmunkából áll. A terepmunka szakaszai során számos vizuális és digitális módszertani eljárás is bevezetésre kerül, s az ezek segítségével készített anyagokból nagy terjedelmű, multimodális adatbázis jön létre. Cikkemben néhány, eddig sikeresnek bizonyult módszert mutatok be, különös tekintettel arra, hogy ezek segítségével hogyan válaszolhatók meg a kutatási kérdéseim. A kötet témájához igazodva kutatásomnak a nyelvitájkép-kutatások között elfoglalt helyét i…
Sustained attention required for effective dimension-based retro-cue benefit in visual working memory
2023
In visual working memory (VWM) tasks, participants’ performances can be improved through the use of dimension-based retro-cues, which direct internal attention to prioritize a particular dimension (e.g., color or orientation) of VWM representations even after the stimuli disappear. This phenomenon is known as the dimension-based retro-cue benefit (RCB). The present study investigates whether sustained attention is required for the dimension-based RCB by inserting interference or interruption between the retro-cue and the test array to distract attention. We tested the effects of perceptual interference or cognitive interruption on dimension-based RCB when the interference (Experiments 1 and…
视觉工作记忆存储的表征单位 [The Representation Unit of Visual Working Memory]
2022
The visual working memory is a limited storage system in which people could flexibly process the representations to complete the task. Among studies on the capacity of visual working memory, the representation unit is a prior subject. Previous research employs the change-detection paradigm and the recall paradigm to explore the nature of representations when features of diverse dimensions and different-level features of the same dimension are stored in the visual working memory. These studies elicit two binary hypotheses: the object-based representation hypothesis backs that those diverse features are bound on the object and form a whole, while the feature-based representation hypothesis su…
Visual working memory resource allocation mechanism in consolidation and maintenance phase
2018
Visual working memory (VWM) is a system for actively maintaining visual information to meet the needs of an ongoing task. It allows individuals to store visual input information from a complex outside environment and provides storage space as an information buffer platform to help integrate information into a continuous visual experience. This research examined the consolidation and maintenance phase of the VWM resource allocation mechanism. Four aspects of this issue were investigated. First, resource allocation in VWM consolidation was investigated for different materials, and it was determined whether VWM resources were allocated in a serial manner for orientation materials but in a limi…
The mechanism of retro-cue effect in visual working memory : Cognitive phase separation
2020
Retro-cue effect (RCE) refers to the phenomenon that individuals can use retro-cues to improve their visual working memory (VWM) performance of target items after memory stimuli disappear. To explain the mechanism of RCE in VWM, five different hypotheses have been proposed by previous studies: the hypothesis of enhancing target representations, the hypothesis of forgetting non-target representations, the hypothesis of preventing memory degradation, the hypothesis of preventing interference from probe array and the hypothesis of cognitive phase separation. Although RCE has been repeatedly observed in previous studies, the mechanism of RCE remains unclear. In this study, we conducted three ex…
