To date, there is no functional account of the visual perception of gaze in humans. Previous work has demonstrated that left gaze and right gaze are represented by separate mechanisms. However, these data are consistent with either a multichannel system comprising separate channels for distinct gaze directions (e.g., left, direct, and right) or an…

Multichannel EEG traces from healthy subjects are used to investigate the brain's self-organisation tendencies during two different mental arithmetic tasks. By making a comparison with a control-state in the form of a classification problem, we can detect and quantify the changes in coordinated brain activity in terms of functional connectivity.…

We recently proposed a multi-channel, image-filtering model for simulating the development of visual selective attention in young infants (Schlesinger, Amso & Johnson, 2007). The model not only captures the performance of 3-month-olds on a visual search task, but also implicates two cortical regions that may play a role in the development of…

Higher education in Canada has rich features: the unique system of educational administration and policy; the distinct features of university management model; dynamic international education; and flexible and diverse in the school system and the financing system. Drawn from the four aspects, it could be used for reference in China's higher…

Purpose: To clarify if large numbers of wide dynamic range compression channels provide advantages for vowel identification and to measure its acoustic effects. Methods: Eight vowels produced by 12 talkers in the /hVd/ context were compressed using 1, 2, 4, 8, and 16 channels. Formant contrast indices (mean formant peak minus mean formant trough;…

Unilateral hearing in childhood restricts input along the bilateral auditory pathways, possibly causing permanent reorganization. In this study we asked: (i) do the auditory pathways develop abnormally in children who are bilaterally deaf and hear with a unilateral cochlear implant? and (ii) can such differences be reversed by restoring input to…

Based on a specially adapted questionnaire, research was carried out to explore how resources in modern distance learning were being applied in rural elementary and middle schools in Western China, in order to enhance the usefulness of the allocated resources. One particular distance learning project was used as the subject of the study, and…

Drafted for the Learning Technologies for Basic Education project, this document assembles case studies which provide an overview of multichannel learning, or reinforce learning through the use of several instructional paths and various media including print, broadcast, and online. Through the cases, multichannel learning is depicted as an…

Understanding the functioning of the brain is hindered by a lack of knowledge of the full complement of neurotransmitters and neuromodulatory compounds. Single cell measurements aid in the discovery of neurotransmitters used by small subsets of neurons that would be diluted below detection limits or masked by ubiquitous compounds when working with…

Describes a multichannel analyzer built using eight-bit S-100 bus microcomputer hardware. The output modes are an oscilloscope display, print data, and send data to another computer. Discusses the system's hardware, software, costs, and advantages relative to commercial multichannels. (Author/GA)

Examines multichannel learning, using learning channels such as teachers, to connect learners to knowledge, skills, and information found in the immediate learning environment and the community or delivered from a distance. Also discusses international use of multichannel learning as educational development in the Philippines and Haiti. (JMV)

The effect of the reduction of the temporal envelope produced by multichannel compression on recognition was examined in 16 listeners with hearing loss, with particular focus on audibility of the speech signal. Multichannel compression improved speech recognition when superior audibility was provided by a two-channel compression system over linear…

Describes an undergraduate laboratory project that combines microprocessor programing, interfacing, and system design to produce an inexpensive multichannel analyzer. (Author/CS)

The Internet has brought significant changes to the retail industry because it revolutionizes how information is transmitted and accessed. The main objective of this research is to enhance our understanding of people's adoption of the Internet and its implications for retail competition. This dissertation consists of two essays. The first essay…

Describes a microcomputer-based multichannel analyzer (MCA) in which the front end is connected to a microcomputer through a custom interface. Thus an MCA System of 1024 channel resolution, programmable in Basic rather than in machine language and having moderate cost, is achieved. (Author/SK)
