Computational methods for querying and sampling the Twitter disinformation datasets

This study attempts to apply computational methods to the Twitter Election Integrity Datasets in order to derive a basic descriptive overview of this disinformation data, and to suggest some possible routes for developing these methods to address future research questions. The results indicate substantial variations in tweet frequency over time and geographical regions, as well as differences in relative importance of tweet words across regions. Aggregated tweet measures provide basic descriptive statistics for the datasets

Effects of online advertising on children's visual attention and task performance during free and goal-directed internet use : A media psychology approach to children's website interaction and advert distraction

This dissertation consists of four eye-tracking studies that investigate how salient online advertising and children's level of executive function contributes to their advert distraction. In Study 1, children aged 9 were instructed to surf freely on the internet while all advert material appearing on-screen was registered. The analyses examined how perceptual prominence in each online advert was related to children's visual attention. In Study 2, a mock-up advergame website was designed with controlled advert conditions, and children aged 9 and 12 were instructed to solve a number of in-game tasks. This study investigated the combined effects of perceptual prominence (e.g. abrupt onset) and content relevance (e.g. personalized content) on children's advert distraction. The results of the first two studies showed significant positive effects of advert saliency on children's visual attention. Due to the task-oriented research design used in the second study, it was possible to interpret these effects on visual attention in terms of advert distraction. Both studies showed that higher levels of inhibitory control in children significantly decreased the effects of advert saliency on visual attention and advert distraction.The following two studies, investigated how advert animation affected children's online reading comprehension and information search on commercial websites. In Study 3, children aged 9 were presented with factual texts that they were instructed to read in order to answer comprehension questions. Each text was presented on a web page which also featured static or animated online adverts. In Study 4, children aged 9 were instructed to solve two online task types featuring concurrent online advertising: reading and information search. The results of these studies showed that animated online advertising had significant negative effects on children's task performance. In the third study, it was found that animated adverts had a negative effect on children's reading comprehension, and that this negative effect was stronger among children with low levels of inhibitory control. The fourth study found that advert animation had a significant positive effect on children's cognitive load across task types. Taken together, this dissertation project has studied children's online advert distraction in a wide range of realistic internet usage situations

Children’s attention to online adverts is related to low-level saliency factors and individual level of gaze control

Twenty-six children in 3rd grade were observed while surfing freely on their favourite websites. Eye movement data were recorded, as well as synchronized screen recordings. Each online advert was analyzed in order to quantify low-level saliency features, such as motion, luminance and edge density. The eye movement data were used to register if the children had attended to the online adverts. A mixed-effects multiple regression analysis was performed in order to test the relationship between visual attention on adverts and advert saliency features. The regression model also included individual level of gaze control and level of internet use as predictors. The results show that all measures of visual saliency had effects on children’s visual attention, but these effects were modulated by children’s individual level of gaze control

RÖST OCH INSKRIPTION : Utkast till den inre monologens teckenteori

Uppsatsen Röst och inskription. Utkast till den inre monologens teckenteori kan sammanfattas som ett försök att beskriva och förklara strukturella och funktionella egenskaper hos inre monolog (i engelsk litteratur inner speech), samt relatera dessa egenskaper till ?yttre?, dialogiskt talspråk. En axial grundtanke som löper genom hela undersökningen är att monologen inte utan vidare låter sig reduceras till en enkel formel som ?talspråk minus röst? etc., utan att monologen bör anses betingad av andra lingvistiska förutsättningar, bland vilka frånvaron av fysisk röstbildning bara är en bland flera faktorer
