Children can only develop spoken language through consistent exposure to the acoustic cues that comprise speech and language. Until recently, hearing levels from the clinical audiogram were the primary measure used to define typical hearing and the presence or degree of a child's hearing loss. While the clinical audiogram remains an important…

This paper summarizes recent research on functions of the cochlea of the inner ear. The cochlea is described as the seat of the first step in the auditory sound analysis and transduction of mechanical vibration into electrochemical processes leading to the generation of neural action potentials. The cochlea is also described as a frequent seat of…

This study examined changes in infants' performance in detecting tones as a funtion of time. Stimuli were presented in blocks of fixed frequency and intensity, rather than in random order. The findings of earlier studies that an observer can reliably tell from a 1-month-old's behavior when a pure tone is being presented, and that reinforcement of…

This paper describes three experiments which demonstrated the presence of binaural perception abilities (the ability to use both ears) in 4-month-old but not in 2-month-old infants. All of the experiments employed a visual fixation habituation-dishabituation paradigm in which infants were given a series of visual fixation trials while binaural…

This paper describes two experiments conducted to replicate the reported findings (Entus, 1975) that infants demonstrate a right ear advantage in the perception of dichotically presented syllables. Using the non-nutritive sucking paradigm, 48 infants 1-3 months of age were presented with verbal stimuli contingent upon criterion level sucking.…

Sophisticated neurological research shows that early problems with auditory perception can result in long-range negative effects for the linguistic processes in general, and such long-range effects must be assumed to be correlated with induced degenerative changes in the auditory system and perhaps in the brain's linguistic sector. This research…

A study was conducted to determine if a difference existed in the discrimination scores of normal hearing subjects when listening to pre-recorded male and female talkers. The talkers were, three females and three males, all native Southern Californians, to control dialectical differences. The listeners were eight females and eight males, aged 18…

Auditory imagination is used in this paper to describe a number of issues and activities related to sound and having to do with listening, thinking, recalling, imagining, reshaping, creating, and uttering sounds and words. Examples of auditory imagination in religious and literary works are cited that indicate a belief in an imagined, expected, or…

It was reasoned that if the right ear/left brain hemisphere is more efficient than the left ear/right hemisphere at extracting the meaning of a sentence, then verbatim information presented to the right ear may be more difficult to retrieve than verbatim information presented to the left ear immediately after the sentence is heard. This idea was…

This study used an eclectic, qualitative research design to explore the effects of visual and verbal variables on affective response and cognitive learning in four different groups of students. The four design imperatives of the study were: (1) both of the primary learning senses (sight and hearing) had to be included in the study; (2) the inquiry…

A near-ultrasonic pure tone of 15,570 Herz generated by flyback transformers in computer and video display terminal (VDT) monitors may cause severe non-specific irritation or stress disease in operators. Women hear higher frequency sounds than men and are twice as sensitive to "too loud" noise. Pure tones at high frequencies are more…

Language processing is the abstraction of meaning from a physical signal, such as a sequence of speech sounds. Processing a spoken message requires a series of transformations that begin with the acoustic signal arriving at the ears and end with meaning in the mind of the listener. The goal of this information-processing model is to describe how…

Yugoslav elementary school students of English as a second language were the subjects of a longitudinal study to determine factors influencing the acquisition of correct English pronunciation. The students were tested for their ability to articulate 32 sounds within ten specific English words. The test was administered each year from the second…

The preschool teacher is in the unique position of being able to identify children who have developed language and speech problems during their early years. This paper is a detailed resource for preschool teachers on hearing and speech problems. Its purpose is two-fold: to emphasize the important role the preschool teacher plays in the lives of…
