Dichotic listening procedures have been used to assess cerebral lateralization in normal subjects. One particularly useful technique is the use of stimuli that fuse into a single percept. Although this procedure has many advantages over other dichotic listening methods, it is particularly susceptible to stimulus dominance, which acts as noise in a subject's response data, thus reducing the powe...

The presentation of visual stimuli of moving mouth is known to affect the phoneme perception of the auditory stimuli during natural speech, and provides important insights into the scientific and technological study of speech. In order to investigate the laterality of the audio-visual integration we studied the relationship between the McGurk effect (McGurk and McDonaold 1976) and Right Ear Adv...

Objectives: All subjects suspected of Central Auditory Processing Disorder (CAPD) were previously tested by free recall dichotic digits test (DDT). The study objective was normalization and reliability evaluation of two-pair DDT in 750 native Persian subjects aged 8 to 12 years. Materials: A total of 750 subjects were divided into five age groups varying between 8 years and 12 years and 11 mon...

PURPOSE To verify the speech recognition processes in a monoaural task and in a binaural integration task with dichotic listening, and to compare them to the cognitive processing in elderly subjects pre and post hearing aid acclimatization. METHODS Participants were 60 elderly subjects of both genders, ranging in age from 61 to 85 years. They were evaluated for cognitive aspects by means of t...

BACKGROUND AND PURPOSE This study aimed to determine the effects of anterior temporal lobectomy with amygdalohippocampectomy (ATL-AH) on central auditory processing (CAP) in patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS), and to identify factors that may contribute to the postoperative worsening of CAP. METHODS Frequency-pattern, duration-pattern, and dichoti...

The human auditory cortex plays a special role in speech recognition. It is therefore necessary to clarify the functional roles of individual auditory areas. We applied functional magnetic resonance imaging (fMRI) to examine cortical responses to speech sounds, which were presented under the dichotic and diotic (binaural) listening conditions. We found two different response patterns in multipl...

INTRODUCTION Dichotic listening tests should be used in local languages and adapted for the population. OBJECTIVE Standardize the Brazilian Portuguese version of the Dichotic Sentence Identification test in normal listeners, comparing the performance for age and ear. METHODS This prospective study included 200 normal listeners divided into four groups according to age: 13-19 years (GI), 20-...

The presentation of visual stimuli of moving mouth is known to affect the phoneme perception of the auditory stimuli during natural speech, and provides important insights into the scientific and technological study of speech. In order to investigate the laterality of the audiovisual integration we studied the relationship between the McGurk effect (McGurk and McDonaold 1976) and Right Ear Adva...
