Auditory Processing And Speech Perception

Front 1

Listener must be able to

Back 1

- perceive their characteristic spectral shapes
- update their perception of the acoustic characteristics to follow the flow of speech
- follow within phoneme changes that are cues in co-articulation

Front 2

Left Cerebral Hemisphere - Left Temporal Lobe

Back 2

serves as the primary area for language and audition and the extraction of the linguistic features of speech

Front 3

The Right Hemisphere

Back 3

has the ability to perceive speech on a rudimentary acoustic level, but when disconnected from the left hemisphere, speech cannot be identified or classified

Front 4

Nerve Transmissions Extend to

Back 4

- the secondary auditory areas of the brain
- which are responsible for the acoustic-linguistic association that enables recognition, comprehension, and formation of spoken language.

Front 5

Connections with the tertiary areas of the brain including sensory and motor functions

Back 5

allows for cross modal communication and integration of information

Front 6

What causes highly redundant signal transmission systems

Back 6

multiple pathways that carry information through the system

the increasing number of cells available for response

and the varied cell responses

Front 7

Contralateral Auditory Pathways

Back 7

Are the dominant pathways of transmission, yielding the right-ear-advantage on speech perception tasks

Front 8

Phonetic distinctions

Back 8

are based on transitional elements occurring only in the left hemisphere

Front 9

Temporal Sequencing

Back 9

takes place in the right temporal lobe

Front 10

midbrain region functions

Back 10

as a binaural integration mechanism and mediator of lateralization phenomena

Front 11

Suprasegmentals

Back 11

- are processed in the right hemisphere.
- have been shown to improve listener accuracy, particularly in difficult listening situations, as well as segregating competing sounds

Front 12

Plasticity and maturation are dependent in part upon

Back 12

stimulation

Front 13

Contralateral pathways

Back 13

are stronger and more numerous than the ipsilateral pathways

Front 14

ipsilateral pathways

Back 14

- are capable of transmitting the appropriate neural signal
- are suppressed by the stronger contra

Front 15

Temporal processing is imprtant for

Back 15

discrimination of subtle cues such as voicing and discrimination of similar words

Front 16

the first 100-125 msec of an auditory stimulus

Back 16

is the most critical for stimulus recognition

Front 17

Suprasegmentals

Back 17

have been shown to improve listener accuracy, particularly in difficult listening situations, as well as segregating competing sounds

Front 18

task complexity

Back 18

affects the degree of mental effort and the amount of time that needs to be expended

Front 19

a high degree of internal redundancy

Back 19

permits that accurate processing will occur under conditions of low external redundancy

Front 20

along the auditory pathways and within the auditory cortex

Back 20

there are specific areas that respond to specific incoming frequencies, enabling the primary auditory cortex to be responsible for point-to-point sensation, signal reception, and acoustic analysis of incoming signals

Front 21

The brain organizes and adapts itself to

Back 21

external or internal changes

Front 22

brain "plasticity"

Back 22

indicates new neural connections can be developed, and existing connections altered
