A psychophysical investigation of quantum cognition: An interdisciplinary synthesis
… thesis reports the results of several empirical investigations which focus on the applicability of quantum cognition to psychophysical perceptual processes. Specifically, we experimentally tested several a priori hypotheses concerning 1) constructive measurement effects in sequential perceptual …

A psychophysical investigation of audio-visual timing in the millisecond range.
The experiments described in this thesis use psychophysical techniques and human observers to investigate temporal processing in the millisecond range. The thesis contains five main sections. Introductory chapters provide a brief overview of the visual and auditory systems, before detailing our …

Psychophysical investigation of the real-ear attenuation of hearing protection devices under different sound-field diffusivity conditions
… room surface treatment with absorptive panels. A psychophysical real-ear-attenuation-at-threshold procedure was used to obtain attenuation data. The results showed small, but statistically significant, differences in attenuation among the three environments for specific test frequencies. Due to …

The perceived timing of events across different sensory modalities. A psychophysical investigation of multisensory time perception in humans.
The experiments reported within this thesis use psychophysical techniques to examine the factors which determine perceived multisensory timing in humans. Chapters 1 and 2 describe anatomical and psychophysical features of temporal processing, respectively, whilst Chapter 3 introduces the reader to …

A psychophysical investigation of human visual perceptual memory. A study of the retention of colour, spatial frequency and motion visual information by human visual short term memory mechanisms.
The aim of this thesis was to investigate how visual information is organised in perceptual short term memory, with special interest in colour, spatial frequency and velocity. Previous studies of VSTM have indicated the existence of specific memory mechanisms for visual attributes such as …

A psychophysical study of visual texture
… in psychological research has been the investigation of the ways in which an observer can differentiate or discriminate various sensory events in relation to some objective dimension of the event. Furthermore, the features of sensory events investigated have been abstract properties of …

Physical and psychological factors in the use of mouthpiece force in trumpet playing
… players across the range of tests. 3) An investigation was carried out on the assessments by trumpet players of the mouthpiece force usage of other players. The judgments involved rating photographs of players performing notes at known force levels. Groups of subjects differing in …
