The purpose of this study was to determine if peripheral hearing loss of varying degrees in elderly subjects affected performance on monotic auditory processing disorder (APD) tests. A battery of monotic APD tests was administered to a group of well-educated and high-functioning older adults who were divided into three subgroups based on hearing acuity but similar in age: (1) normal hearing out...

Auditory processing disorders contribute to communication difficulties in children with language-based learning impairments and in older adults who have trouble hearing in background noise. Therefore, deficits in auditory processing are widespread among these diverse populations. For this reason, it behooves both scientific and clinical communities to consider optimum techniques for assessing a...

Introduction: Diabetes mellitus is most common chronic disease characteristic by carbohydrate metabolic disorder in which absolute or relative deficiency insulin and various pathological changes the body system. The central nervous system disorders among affected toxic effect hyperglycemia. Auditory temporal processing one of important abilities may be diabetes. However, extent nature manifesta...

This dissertation was motivated by two questions: 1) Do children with developmental disorders have reliable cortical characteristics that distinguish them from control children or that are unique for different disorder-subtypes? 2) Do these cortical characteristics reflect behavioural changes effectuated by an intervention? Five studies that contribute to answering these questions will be prese...

I f you spend much time around audiologists interested in auditory processing disorder (APD), sooner or later you will hear the statement that a test for APD must be ''simple, quick, cheap, and easily scored.'' Otherwise, it is solemnly averred, ''clinicians will not use it.'' This mantra has achieved virtually biblical status. The assumption seems to be that one can make the diagnosis of APD i...

similarity between the stimuli used in the two experiments. In the IAC experiment, the dimension of change (Y axis) is interaural difference. Correlated noise is hypothesized (Durlach 1963) to be represented as a constant ‘zero’ value, whereas uncorrelated noise is represented as a randomly fluctuating value. The size of the black segments symbolizes the temporal resolution of binaural processi...

This selected overview of audiovisual (AV) speech perception examines the influence of visible articulatory information on what is heard. Thought to be a cross-cultural phenomenon that emerges early in typical language development, variables that influence AV speech perception include properties of the visual and the auditory signal, attentional demands, and individual differences. A brief revi...

BACKGROUND: Difficulty in speech understanding in the presence of background noise or competing auditory signals is typically present in central auditory processing disorders. These disorders may be diagnosed in Alzheimer's disease as a result of degeneration in the central auditory system. In addition perception and processing of speech may be affected. MATERIAL AND METHODS: A MEDLINE research...
