In noisy and complex environments, human listeners must segregate the mixture of sound sources arriving at their ears and selectively attend a single source, thereby solving a computationally difficult problem called the cocktail party problem. However, the neural mechanisms underlying these computations are still largely a mystery. Oscillatory synchronization of neuronal activity between cortical areas is thought to provide a crucial role in facilitating information transmission between spatially separated populations of neurons, enabling the formation of functional networks. In this thesis, we seek to analyze and model the functional neuronal networks underlying attention to speech stimuli and find that the Frontal Eye Fields play a central 'hub' role in the auditory spatial attention network in a cocktail party experiment. We use magnetoencephalography (MEG) to measure neural signals with high temporal precision, while sampling from the whole cortex. However, several methodological issues arise when undertaking functional connectivity analysis with MEG data. Specifically, volume conduction of electrical and magnetic fields in the brain complicates interpretation of results. We compare several approaches through simulations, and analyze the trade-offs among various measures of neural phase-locking in the presence of volume conduction. We use these insights to study functional networks in a cocktail party experiment. We then construct a linear dynamical system model of neural responses to ongoing speech. Using this model, we are able to correctly predict which of two speakers is being attended by a listener. We then apply this model to data from a task where people were attending to stories with synchronous and scrambled videos of the speakers' faces to explore how the presence of visual information modifies the underlying neuronal mechanisms of speech perception. This model allows us to probe neural processes as subjects listen to long stimuli, without the need for a trial-based experimental design. We model the neural activity with latent states, and model the neural noise spectrum and functional connectivity with multivariate autoregressive dynamics, along with impulse responses for external stimulus processing. We also develop a new regularized Expectation-Maximization (EM) algorithm to fit this model to electroencephalography (EEG) data.

The purposes of this study were (1) to ascertain the total absolute change scores between student basic interest scale scores on the Strong-Campbell Interest Inventory (SCII) and like scores on the audio interest inventory (All), and the audio-visual interest inventory (AVII), which are based on the SCII; and (2) to ascertain if a statistically significant relationship exists between students with high reading ability and students with low reading ability, when different test-retest inventory administration methods are used.

This thesis presents the results of a study conducted to determine if visual aids impacted the general science capabilities of middle school students.

Previous research shows that integration of the senses is interchangeably dependent by  temporal neural mechanisms. One unsolved problem is how sensory timing differences in the brain is processed. In this systematic review (K = 18), audio-visual behavioral task paradigms are investigated with a focus on temporal binding window estimates. The results showed among other things that temporal integration is an adaptive neural process and that temporal acuity increases with age. Measurements between studies were sometimes incompatible which limited conclusions. Future studies should focus on standardizing operational parameters and compare within and between group designs.

This study is focused on how technology is employed as educational support media in distance education. The aim is to establish the availability and accessibility of interac¬tive television for both guidance teachers and students in rural, remote and previously disadvantaged communities. Interactive television could be used to support the primary modes of education, namely, contact education on campus or at remote sites, paper-¬based distance education and Web-based distance education for in-service education and training of guidance teachers. The TELETUKS schools project is cursorily pre¬sented as an example of a technology-enhanced delivery system to facilitate interactive television learning. The ITV has the potential to be cost-effective, saving on travelling costs and reaching for increased numbers of upgrading guidance teachers per unit time. A comprehensive interactive television model for in-service training of the guidance teacher in the Northern Province is presented. / Thesis (PhD (Educational Guidance and Counselling))--University of Pretoria, 2007. / Educational Psychology / unrestricted

Das Projektposter stellt die Einbindung hochqualitativer audiovisueller Medien zur Lernunterstützung im Kontakt- und Selbststudium einiger theoriegeleiteter, sportpraktischer Veranstaltungen im Bachelorstudium dar. Im Modul Turnen, Schwimmen, Leichtathletik werden komplexe Bewegungselemente sportartübergreifend und theoriegeleitet vermittelt. Die umfangreichen Bewegungskompetenzen werden u.a. mittels bestehender Bewegungsverwandtschaften, aber auch anhand erkennbarer Divergenzen in den Modul sportartenverstärkend bzw. kontrastrierend erfahrbar gemacht. Der Qualitätsanspruch an lernförderliche Medien sowie differenzierte Zugänge für diesen speziellen Kompetenzerwerb werden im Projektposter deutlich.

The problem of this study was to determine if significant differences in scores attained by students on academic achievement, problem-solving, and attitudes were associated with closed-circuit television observations. More specifically, the problem was resolved into seeking solutions to the following! 1. Will college students' academic achievement be extended through television observations of children in classroom situations? 2. Will college students' ability to solve problems be improved through television observations? 3. Will college students' attitudes toward teacher-pupil relationships be affected through television observations?

The problem of this study was to compare the effectiveness of two methods of teaching Spanish by non-specialist teachers in grade four. This study was planned to investigate the effectiveness of two programs designed to teach Spanish to non-Spanish-speaking fourth grade students.
