Associations between neonatal cry acoustics and visual attention during the first year

2019

It has been suggested that early cry parameters are connected to later cognitive abilities. The present study is the first to investigate whether the acoustic features of infant cry are associated with cognitive development already during the first year, as measured by oculomotor orienting and attention disengagement. Cry sounds for acoustic analyses (fundamental frequency; F0) were recorded in two neonatal cohorts at the age of 0–8 days (Tampere, Finland) or at 6 weeks (Cape Town, South Africa). Eye tracking was used to measure oculomotor orienting to peripheral visual stimuli and attention disengagement from central stimuli at 8 months (Tampere) or at 6 months (Cape Town) of age. Only a m…

Speed detection of battery-free nodes based on RF Wireless Power Transfer

2020

In the Internet of Things (IoT) era, Wireless Sensor Networks (WSNs) are rapidly increasing in terms of relevance and pervasiveness thanks to their notable real-time monitoring performance across several fields, including industrial, domestic, military, biomedical, commercial, environmental, and other sectors. A highly attractive implementation of WSNs is asset tracking with accurate data regarding the location and transportation conditions of goods, equipment, and the like. One highly promising application of WSNs along these lines is the remote speed monitoring of goods, ideally with battery-free sensor nodes that do not require any maintenance. This, however, represents a major challenge…

Development of novel probes for enterovirus B group to study uncoating and infection

2016

Enterovirus B group (EV-B) viruses are important human pathogens which cause a variety of diseases from mild respiratory illnesses to more severe acute infections such as myocarditis and meningitis. EV-Bs have also been associated with chronic infections and autoimmune diseases such as type I diabetes. Because of their significance, better and more accurate methods are necessary to track and visualize viruses in vitro and in vivo. This thesis focus on the development of novel probes to label viruses site-specifically and track infection in vitro. First, we established a covalent conjugation between gold nanocluster markers and EV-B viruses. We were able to visualize through electron microsc…

Teachers' visual focus of attention in relation to students' basic academic skills and teachers' individual support for students: An eye-tracking stu…

2022

This study investigated how teachers' visual focus of attention is associated with students' basic academic skills and teachers' individual support for students in basic academic skills in authentic classroom settings. Teachers' (N = 46) visual focus of attention in the classroom was measured with mobile eye-tracking, and students' (N = 879) literacy and math skills were tested in Grade 1. The results revealed that teachers' visual focus of attention in terms of fixation counts correlated with students' basic academic skills and teachers' individual support for students in literacy and math. Two case studies showed that teachers' visual focus of attention varied among students with differen…

Muistisairaan ihmisen kokemukset teknologiasta osana arkea - turvaa vai tunkeilevuutta

2018

Tässä tutkimuksessa selvitettiin muistisairaiden ihmisten arkea tukevan teknologian käyttöönottoa ja heidän sekä heidän läheistensä kokemuksia teknologian käytöstä. Tutkimuksen viitekehyksenä toimi Lawtonin ekologinen malli. Tutkimuksessa käytettiin etnografista näkökulmaa haastattelemalla ja havainnoimalla muistisairaita ihmisiä teknologian käyttötilanteissa. Ensimmäinen vaihe toteutettiin vuosina 2004-2007. Ensimmäisessä vaiheessa kohderyhmänä olivat 25 muistisairautta sairastavaa kotona yksin tai omaishoitajansa kanssa asuvaa henkilöä sekä heidän läheistään ja viisi vastaajaa kuntien kotihoidosta. Koteihin vietiin yhteensä 29 erilaista laitetta. Toinen keruuvaihe toteutettiin vuosina 201…

Movement Detection with Event-Based Cameras: Comparison with Frame-Based Cameras in Robot Object Tracking Using Powerlink Communication

2018

Event-based cameras are not common in industrial applications despite the fact that they can add multiple advantages for applications with moving objects. In comparison with frame-based cameras, the amount of generated data is very low while keeping the main information in the scene. For an industrial environment with interconnected systems, data reduction becomes very important to avoid network congestion and provide faster response time. However, the use of new sensors as event-based cameras is not common since they do not usually provide connectivity to industrial buses. This work develops a network node based on a Field Programmable Gate Array (FPGA), including data acquisition and trac…

Reading in students with deafness: An eye-movement research

2020

This thesis focused on describing the online reading pattern of deaf and hard of hearing students (DHH) and the factors that affect it. Previous studies have widely reported and described the difficulties that students with DHH demonstrate during reading. However, there are still some questions in which results do not converge (e.g., Do students with DHH ignore grammatical cues during sentence reading? Do they adapt their reading according to text demands?). Therefore, these questions remain open to new procedures that can disentangle or at least contribute to the understanding of DHH students' reading problems. So far, the vast majority of the studies have approached this issue by measurin…

The Timecourse of Sentence Processing in the Brain

2015

This chapter discusses the current state of the art with regard to the timecourse of sentence processing in the brain. It outlines the challenges associated with studying timecourse information at the sentence level from a neurobiological perspective and describes competing theoretical and empirical perspectives in this domain. In addition to drawing on findings from neurophysiological methods (electroencephalography [EEG]; magnetoencephalography [MEG]), insights from eye movement measures during natural reading are also taken into account. The chapter concludes that while we are currently unable to make absolute claims about the timecourse of sentence processing from a neurobiological pers…

Students’ approaches to solving R-FCI tasks observed by eye-tracking method

2018

This study sought to assess the representational format of task options in the representational variant of the force concept Inventory (R-FCI) test, namely its impact on students’ problem-solving approaches. This was done with the help of eye-tracking equipment. 35 high-school students solved four tasks, mainly from the R-FCI test, which sought to assess the student’s understanding of Newton’s 1st and 2nd Law of Motion. As they were trying to solve the problems, their gazes were tracked by TobiiTX300. A comparison between students who provided the correct and incorrect answer was subsequently carried out. The correctly answering students very quickly found the correct solution both in verba…
