Temporal characteristics of spoken consonants as discriminants in automatic speech recognition
Thesis
Green, P. D. Temporal characteristics of spoken consonants as discriminants in automatic speech recognition. https://keele-repository.worktribe.com/output/412678

Three time-varying functions, which can be extracted. directly from the raw speech waveform, are of importance in the field of automatic speech recognition. These functions arc the zero-crossing rate, the turnaround (local maximum or minimum) rate an...

Neuroanatomical segregation of texture-sensitivity in feline striate cortex
Thesis
Edelstyn, N. Neuroanatomical segregation of texture-sensitivity in feline striate cortex. https://keele-repository.worktribe.com/output/417350

Recordings were obtained from striate cortical neurones in cats lightly anaesthetized with nitrous oxide/oxygen supplemented with halothane as necessary: muscle relaxant (gallamine triethiodide) was administered intravenously. Complex neurones were s... Read More about Neuroanatomical segregation of texture-sensitivity in feline striate cortex.

Detection of frequency and intensity changes using synthetic vowels and other sounds
Thesis
Cosgrove, P. Detection of frequency and intensity changes using synthetic vowels and other sounds. https://keele-repository.worktribe.com/output/417341

Formant frequency transition detection thresholds In synthetic vowels were Investigated for their dependence on formant number, vowel type and duration of frequency transition. With transitions In final position It was found that F2 Is easier to dete... Read More about Detection of frequency and intensity changes using synthetic vowels and other sounds.

Some studies of spontaneous and evoked acoustic emissions from the human ear
Thesis
Some studies of spontaneous and evoked acoustic emissions from the human ear. https://keele-repository.worktribe.com/output/417045

Several studies of spontaneous and evoked oto-acoustic emissions (SOAEs and EOAEs) and their relationship to norsal and pathological hearing mechanism are described.
1. A computer model was developed to study the theory that the EOAE is produced by... Read More about Some studies of spontaneous and evoked acoustic emissions from the human ear.

Aspects of chromatic and temporal processing in normal and impaired human vision
Thesis
Aspects of chromatic and temporal processing in normal and impaired human vision. https://keele-repository.worktribe.com/output/417041

A psychophysical study was made of post-receptoral processing In the human visual system. The first series of experiments investigated normal red-green opponent-colour function by Means of a paradigm in which a white auxiliary field was made spatiall...

Variable and constant errors of perceived angle size
Thesis
Hakiel, S. Variable and constant errors of perceived angle size. https://keele-repository.worktribe.com/output/413663

Experiments were carried out to characterise the perception of angles in terms of the acuity and constant error of comparisons of acute angle sizes. Both measures, determined by the forced choice method of constant stimululi, were found to increase l... Read More about Variable and constant errors of perceived angle size.

A study of thresholds for signals having changing pitch
Thesis
Pick, G. F. A study of thresholds for signals having changing pitch. https://keele-repository.worktribe.com/output/412956

In this dissertation, the threshold for stimuli with changing pitch has been discussed in terms of some simple psychophysical phenomena. The intention was to seek those effects which could not be explained in such terms, and to examine these further,... Read More about A study of thresholds for signals having changing pitch.

Human visual evoked potentials: a computer aided investigation into their origin and variability
Thesis
Axford, J. Human visual evoked potentials: a computer aided investigation into their origin and variability. https://keele-repository.worktribe.com/output/412966

This thesis is concerned with the measurement of human visual Averaged Evoked Potentials (AEPs) to tachistoscopically presented pattern stimuli, i.e. the sudden appearance and disappearance of patterns into an otherwise;, continuously illuminated dif...

Psychophysical evidence concerning the integration of curvature information in short contours
Thesis
Psychophysical evidence concerning the integration of curvature information in short contours. https://keele-repository.worktribe.com/output/416620

Performance of curvature discrimination was measured for a wide range of stimulus curvatures and sizes, using an adaptive version of the Method of Constant Stimuli. Performance is expressed both in terms of curvature difference thresholds, and effici...

Electrolytic growth processes with applications to adaptive systems
Thesis
Electrolytic growth processes with applications to adaptive systems. https://keele-repository.worktribe.com/output/410413

Two types of electrolytic growth processes have been investigated as possible means of controlling impedances in adaptive systems. One of these entails the growth of conductors by metallic deposition and the other the growth of insulation by anodic o...

Visual comparison of patterns: the significance of pattern transformation and pattern arrangement in the visual field
Thesis
Visual comparison of patterns: the significance of pattern transformation and pattern arrangement in the visual field. https://keele-repository.worktribe.com/output/414664

The two main types of scheme for the internal representation and internal processing of visual stimuli involve either a 'pointlllistic' internal representation to which various internal compensatory transformations can be applied, or a structured, in...

Neuronal organization within the mammalian dorsal lateral geniculate complex and adjacent pulvinar nuclei: a comparative approach
Thesis
Mason, R. Neuronal organization within the mammalian dorsal lateral geniculate complex and adjacent pulvinar nuclei: a comparative approach. https://keele-repository.worktribe.com/output/413541

This dissertation attempts to understand the organization of some of the nuclei which constitute the mammalian visual thalamus through an electrophysiological and histological investigation of the cat and rat aided by an evaluation of comparative neu...

Associative responses to colour and pattern in the human visual system
Thesis
Associative responses to colour and pattern in the human visual system. https://keele-repository.worktribe.com/output/414549

Psychophysical methods have been applied to the following four aspects of the McCollough effect with a view to the elucidation of its mechanism and its locus:
(1) time course of build-up and decay
(2) association of colour with scale of pattern... Read More about Associative responses to colour and pattern in the human visual system.

The McCollough effect: a study of some temporal characteristics
Thesis
The McCollough effect: a study of some temporal characteristics. https://keele-repository.worktribe.com/output/414408

A parametric study was made of the influence of the temporal parameters of stimulation on initial strength and rate of decay of the McCollough Effect. Using a tachistoscope to accurately control stimulus presentation timings, it was shown that the le... Read More about The McCollough effect: a study of some temporal characteristics.
