[15] [16] Similarly, increasing the duration of a stimulus available in a reaction time task was found to produce slightly faster reaction times to visual [15] and auditory stimuli, [17] though these effects tend to be small and are largely consequent of the sensitivity to sensory receptors. [8]
The nonlexical pathway is thought to be more active and constructive as it assembles and selects the correct subword units from various potential combinations. For example, when reading the word "leaf", that its spelling adheres to sound rules, the reader must assemble and recognize the two-letter grapheme "ea" in order to produce the sound "ee ...
The function of the auditory dorsal pathway is to map the auditory sensory representations onto articulatory motor representations. Hickok & Poeppel claim that the auditory dorsal pathway is necessary because, "learning to speak is essentially a motor learning task. The primary input to this is sensory, speech in particular.
Halkiopoulos demonstrated attentional biases by measuring reaction times to auditory probes following neutral and emotional words in the attended and the unattended channels. This method was subsequently used in the visual modality by MacLeod, Mathews and Tata (1986) in what came to be known as the dot probe paradigm.
Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
The most significant period for the development of auditory-visual integration occurs between ages 5–7. During this time, the child has mastered visual-kinesthetic integration, and the child's visual learning can be applied to formal learning focused towards books and reading, rather than physical objects, thus impacting their intellect.
The task is made more challenging by the shifting of modalities between the visual and auditory stimuli. In the five "high demand" sections of the test, the targets are presented frequently. This creates a continuous response set so when the test-taker is suddenly presented with a foil, he or she may find it difficult to "put on the brakes."
Multisensory integration, also known as multimodal integration, is the study of how information from the different sensory modalities (such as sight, sound, touch, smell, self-motion, and taste) may be integrated by the nervous system. [1]
