Nonlinear Representation of Auditory Stimuli Across the Auditory Cortex
… neural evoke activity to pure tones in primary auditory cortex has been systematically studied for many years, as has the spatial organization of these responses. Unlike pure tones, natural sounds possess complex spectro-temporal structures across frequencies. How simple tuning properties scale …

Computational auditory saliency
… be on investigating the role of saliency in the auditory attentional process. In order to identify these salient sounds, we have developed a computational auditory saliency model inspired by our understanding of the human auditory system and auditory perception. By identifying salient sounds we …

Abnormal Anatomy of the Auditory Cortex in Schizophrenic Brains with Auditory Hallucinations
… psychiatric literature has suggested that the auditory cortex region is smaller in people with schizophrenia who experience auditory hallucinations than in normal control individuals. These findings are not without controversy. While there has been significant research considering volumetric …

Cognitive and Auditory Factors Underlying Auditory Spatial Attention in Younger and Older Adults
… harder with age. Three experiments examined the auditory and cognitive aspects of auditory spatial attention in conditions in which the location of the target was uncertain. In all experiments, word identification was measured for target sentences presented with two competitor sentences. On each …

Real-time detection of auditory : steady-state brainstem potentials evoked by auditory stimuli
The auditory steady-state response (ASSR) is advantageous against other hearing techniques because of its capability in providing objective and frequency specific information. The objectives are to reduce the lengthy test duration, and improve the signal detection rate and the robustness of the …

A Comparative Analysis of Tests for Central Auditory Function and Tests for Auditory Processing
… between the results obtained from tests of auditory language performance and those obtained from tests of central auditory performance. The performances of ten learning disabled children were compared with the performances of ten normal achievers on the six auditory language subtests of the …

Effects of altered prenatal auditory experience on postnatal auditory preferences in bobwhite quail chicks
… study examined the influence of altered prenatal auditory stimulation (in the form of embryonic vocalizations altered in repetition rate) on postnatal auditory preferences in precocial bobwhite quail chicks. Results indicate that when embryos are exposed to altered prenatal auditory stimulation in …

Contrastive Learning of Auditory Representations
… use a similar approach to learn more efficient auditory and audio-visual representations. In this thesis, we expand on prior self-supervised methods to learn better auditory and audio-visual representations. We introduce various data augmentations suitable for auditory and audio-visual data and …

Auditory attentional deficit in schizophrenia
<p>Differences in auditory detection performance between schizophrenics and normals were examined in terms of the attentional processes involved. Each of 40 ~s (20 schizophrenics categorized along the dimensions of paranoia, premorbidity, and acuteness; and 20 hospital technical staff) were …

Spatial aspects of auditory salience
Models of auditory salience aim to predict which sounds attract people’s attention, and their proposed applications range from soundscape design to machine listening systems and object-based broadcasting. A few different types of models have been proposed, but one of the areas where most of them …

Psychological Flexibility and Auditory Hallucinations
… values. For people distressed and/or disabled by auditory hallucinations, it is theorised that this experience is responded to in a psychologically inflexible manner: becoming a target for avoidance, control or focus, appraised as more powerful than the person experiencing the voices, and leading …

Models of the auditory threshold
… the advantages of computer models of the human auditory system at threshold are considered. Details of models, based on the properties of pseudo random binary sequences (p.r.b.s.), are then presented. The models consist of an hardware electronic simulation of the auditory threshold and a digital …

Attentional processes in auditory discriminations
<p>A set of experiments is described which assessed the ability of human observers to monitor two earphone channels in order to perform one or two independent frequency discriminations. Performance (d′) was significantly poorer with dichotic stimulus presentation than in monaural control …

Visual and auditory scene parsing
… machine learning approaches to parse visual and auditory signals, including images, videos, and audios. Visual scene parsing refers to densely grouping and labeling of image regions into object concepts. First I build the MIT scene parsing benchmark based on a large scale, densely annotated …
