The two-streams hypothesis is a model of the neural processing of vision as well as hearing. [1] The hypothesis, given its initial characterisation in a paper by David Milner and Melvyn A. Goodale in 1992, argues that humans possess two distinct visual systems. [2] Recently there seems to be evidence of two distinct auditory systems as well.
In psychology, parallel processing is the ability of the brain to simultaneously process incoming stimuli of differing quality. [1] Parallel processing is associated with the visual system in that the brain divides what it sees into four components: color , motion , shape , and depth .
TRACE was created during the formative period of connectionism, and was included as a chapter in Parallel Distributed Processing: Explorations in the Microstructures of Cognition. [3] The researchers found that certain problems regarding speech perception could be conceptualized in terms of a connectionist interactive activation model.
The "dichotic fused words test" (DFWT) is a modified version of the basic dichotic listening test. It was originally explored by Johnson et al. (1977) [25] but in the early 80's Wexler and Hawles (1983) [26] modified this original test to ascertain more accurate data pertaining to hemispheric specialization of language function.
This system compensates for the controversies of limited parallel processing in Broadbent's original findings. A major component of the system entails sensory memory, [11] which is broken down into iconic memory and echoic memory. [12] The aforementioned represent visual and auditory memory respectively, which function preattentively.
However, there is also a long and parallel history of multisensory research. An example is the Stratton's (1896) experiments on the somatosensory effects of wearing vision-distorting prism glasses. [ 11 ] [ 12 ] Multisensory interactions or crossmodal effects in which the perception of a stimulus is influenced by the presence of another type of ...
Neurally, the signs of interrupted or stopped speech can be suppressed in the thalamus and auditory cortex, possibly as a consequence of top-down processing by the auditory system. [2] Key aspects of the speech signal itself are considered to be resolved somewhere in the interface between auditory and language-specific areas (an example is ...
Auditory nerve fibers take this slightly-processed sensory information to the cochlear nucleus where information either converges or diverges into parallel pathways. [25] In Pteronotus parnellii , a CF-FM bat, these parallel pathways process CF and FM harmonics separately and contain neurons that exhibit amplitude, frequency, and harmonic ...
