We used PET to test whether human premotor and posterior parietal areas can subserve basic sensorimotor integration and sensorimotor learning equivalently in response to auditory and visual stimuli, as has been shown in frontoparietal neurons in non-human primates. Normal subjects were studied while they performed a spatial compatibility task. They were instructed to respond to lateralized audi...

[Purpose] Auditory hypersensitivity has been widely reported in patients with autism spectrum disorders. However, the neurological background of auditory hypersensitivity is currently not clear. The present study examined the relationship between sympathetic nervous system responses and auditory hypersensitivity induced by different types of auditory stimuli. [Methods] We exposed 20 healthy you...

Brain activity during reaction time tasks has been reported to consist of stimulus- and response-locked components. The aim of this study is to apply a method for temporally extracting these components from human scalp electroencephalography (EEG) during an auditory simple reaction time task (SR-task). The stimulus- and response-locked components are extracted from each channel of the EEG epoch...

Research has suggested that the left hemisphere of the brain may be specialized for processing auditory speech, whereas the right hemisphere may be specialized for processing nonspeech auditory stimuli. Due to contralaterality in auditory pathways, this functional specialization has been reflected in behavioral advantages for speech stimuli presented to the right ear and for nonspeech stimuli p...

The following study was carried out to know the developmental differences in cognitive inhibition between children and adults using auditory and visual vigilance tasks. A total of 62 Kannada – English bilingual speakers participated, divided into two groups. Test stimuli consisted of single digit numbers (1 to 9), presented randomly through headphones for the auditory vigilance task and visual ...

This document reports the results of two experiments assessing the viability of speech, auditory icons (environmental sounds) and abstract sounds (complex tones) for use as auditory warnings in military cockpits. Experiment One evaluated the comparative ease of learning and retention of these three sound types, with the results demonstrating that speech warnings and auditory icons were learnt a...

Auditory startle reflexes can accelerate simple voluntary reaction times (StartReact effect). To investigate the role of startle reflexes on more complex motor behaviour we formulated two questions: (1) can auditory startle reflexes shorten choice reaction times?; (2) is the StartReact effect differentially modulated when startling auditory stimuli are delivered ipsilaterally or contralaterally...
