Sustained attention encompasses a cascade of fundamental functions. The human ability to implement a sustained attention task is supported by brain networks that dynamically formed and dissolved through oscillatory synchronization. The decrement of vigilance induced by prolonged task engagement affects sustained attention. However, little is known about which stage or combinations are affected by vigilance decrement. Here, we applied an analysis framework composed of weighted phase lag index (wPLI) and tensor component analysis (TCA) to an EEG dataset collected during 80 min sustained attention task to examine the electrophysiological basis of such effect. We aimed to characterize the phase…

Saavutettavuutta kaikille? : viitottujen verkkotekstien laatu ja käytettävyys viittomakielten elinvoimaisuuden ja kielenoppimisen näkökulmasta

2022

Viime aikoina on keskusteltu viittomakielisten ja viittomakielelle tulkattujen verkkotekstien laadusta. Viittomakieliset ovat kokeneet, että viitottujen verkkotekstien laatu vaihtelee paljon. Viitottuja verkkotekstejä käytetään monissa paikoissa kielenopetustyössä, kirjastoissa ja eri medioiden saavutettavuuden kehittämistyössä. Käsittelin maisterintutkielmassani (2021) viitottujen verkkotekstien laatua tekstien käytettävyyden ja kieliasiantuntijoiden näkökulmista. Millainen rooli on kuuroilla, äidinkielisillä kieliammattilaisilla, kääntäjillä ja tulkeilla pienissä viitotuissa vähemmistökielissä? nonPeerReviewed

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…

视觉工作记忆中回溯线索效应的影响因素 [The Influencing Factors of Retro-Cue Effect in Visual Working Memory]

2022

The visual working memory is a temporary storage system, which encodes, maintains and retrieves visual information. The researchers have found that adding retro-cues to the maintenance phase of memory leads to changes in participants’ memory performance, which is the retro-cue effect. The magnitude of the retro-cue effect is not set in stone, but changes with the changes of its influencing factors. However, there is no study to summarize the influencing factors of the retro-clue effect. This paper looked into the articles related to the study of the retro-cue effect and summarized the influencing factors of the retro-cue effect: memory items, maintenance interval time, interference in maint…
