Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed

Event-related potentials to task-irrelevant changes in facial expressions
2009
Abstract Background Numerous previous experiments have used oddball paradigm to study change detection. This paradigm is applied here to study change detection of facial expressions in a context which demands abstraction of the emotional expression-related facial features among other changing facial features. Methods Event-related potentials (ERPs) were recorded in adult humans engaged in a demanding auditory task. In an oddball paradigm, repeated pictures of faces with a neutral expression ('standard', p = .9) were rarely replaced by pictures with a fearful ('fearful deviant', p = .05) or happy ('happy deviant', p = .05) expression. Importantly, facial identities changed from picture to pi…
Long-term physical activity modifies automatic visual processing
2019
Electrophysiologically registered visual mismatch negativity (vMMN) is known to represent automatic visual processing in human visual cortex. Since physical activity (PA) is generally beneficial to cerebrovascular function, we wanted to find out if automatic visual processing is affected by PA. We investigated the connection between long-term leisure-time PA and precognitive visual processing in 32 healthy young males. Participants were divided into active (n = 16) and inactive (n = 16) group according to their leisure-time PA records from the past three years. vMMN was recorded with electroencephalogram using passive oddball paradigm with visual bars. Standard (90%) and deviant (10%) stimu…
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…

Maahanmuuttajien vuorovaikutussuhteet
2006
Uuden ja erilaisen elämäntilanteen, kuten uuden kulttuurisen ympäristön, kohtaaminen edellyttää aina tavalla tai toisella uuteen elämäntilanteeseen ja uuteen ympäristöön sopeutumista. Useat tutkijat määrittelevät sopeutumisen prosessiksi, joka aiheutuu erilaisten ihmisten ja ympäristöjen kohtaamisesta ja välittömästä kontaktista, (esim. Berry 1997; Liebkind 2000; Redfield, Linton & Herskovits 1936). Käsitetäänkö prosessi ainoastaan yksipuolisena muutoksiin reagointina, kuten psykologisina muutoksina ja käyttäytymisen muutoksina, vai vuorovaikutuksellisena prosessina, jossa vuorovaikutuksen osapuolet yhdessä luovat merkityksiä muutosten keskellä, riippuu näkökulmasta.
