Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction
2020
Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…
Brain's capacity to detect abstract regularities from visual stimuli under different attentive conditions- an ERP study
2010
Many previous studies have applied oddball paradigm to study change detection. Although changes within single features have been investigated a lot, the changes in multiple feature conjunctions have not. The aim of our study was to investigate with event-related potentials by applying oddball paradigm, whether the brain can detect abstract regularities in visual stimulus stream when two different features are combined - semantic meaning and color. Participants were shown adjective words written in red and blue print in quasi-random order on a computer screen. In an oddball paradigm, 90 % of the words (‘standard’) followed the rule “words printed in red have a negative meaning and the words …
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…
Sydämen vajaatoimintaa sairastavan elämänlaatu ja tehostettu terveysneuvonta : tuloksia Tehova -projektista
2011
Tutkimuksen tarkoituksena oli selvittää tehostettua terveysneuvontaa saaneiden ja verrokkipotilaiden elämänlaatua vuoden seuranta-aikana sairaalahoidosta kotiutumisen jälkeen. Tutkimusaineisto kerättiin prospektiivisella satunnaistamattomalla kyselytutkimuksella vuosien 2001─2004 välisenä aikana Keski-Suomen keskussairaalassa hoidetuilta sydämen vajaatoimintapotilailta. Tutkimuksessa käytettiin geneeristä elämänlaatumittaria, Nottingham Health Profilea, jonka potilaat täyttivät sairaalassa ennen terveysneuvontaa sekä 3, 6 ja 12 kuukauden kuluttua sairaalahoidon jälkeen. Tutkimukseen osallistui 195 (N) sisäänottokriteerit täyttävää potilasta, joista 99 (n) osallistui tehostettuun terveysneuv…

Kokemuksia vapaaehtoisesta lapsettomuudesta ja sterilisaatiosta -kirjoitusaineisto 2017
2022
Aineisto koostuu vapaaehtoista lapsettomuutta ja sterilisaatiota käsittelevistä kirjoituksista. Kirjoituspyyntöön saivat vastata kaikki itsensä kohderyhmään kuuluvaksi määrittelevät henkilöt. Aineisto on kerätty alun perin pro gradu -tutkielmaan vuonna 2017. Kirjoituskutsun avulla pyrittiin selvittämään mm. sitä, miten päätös vapaaehtoisesta lapsettomuudesta on syntynyt ja millaisia ajatuksia sterilisaatio vastaajissa herättää. Tarkoitus oli saada tietoa myös siitä, miksi sterilisaatioon hakeudutaan ja millaisia vaikutuksia toimenpiteellä on ollut vapaaehtoisesti lapsettomien ihmisten elämään. Haluttiin myös tietää, millaisena tilanteen näkevät ne, jotka toivoisivat toimenpidettä, mutta eiv…
The marketplace vulnerability of low-income unbanked consumers : a developing country perspective
2018
Financial exclusion is recognised as an important element of socio-economic inequality where economically vulnerable groups are excluded from basic financial services. The issue of financial exclusion is mainly concentrated in the world’s developing countries. However, research on the issue of financial exclusion in the field of marketing as well as from the perspective of unbanked consumers is lacking. Although financial exclusion impedes low-income consumers’ welfare, there is a shortage of wellbeing related studies on low-income consumers in the context of developing countries. This doctoral dissertation aims to investigate the ways in which low-income unbanked consumers experience vulne…
