Perceptual processes mediating recognition, including the recognition of objects and spoken words, is inherently multisensory. This is true in spite of the fact that sensory inputs are segregated in early stages of neuro-sensory encoding. In face-to-face communication, for example, auditory information is processed in the cochlea, encoded in auditory sensory nerve, and processed in lower cortical areas. Eventually, these “sounds” are processed in higher cortical pathways such as the auditory cortex where it is perceived as speech. Likewise, visual information obtained from observing a talker’s articulators is encoded in lower visual pathways. Subsequently, this information undergoes processing in the visual cortex prior to the extraction of articulatory gestures in higher cortical areas associated with speech and language. As language perception unfolds, information garnered from visual articulators interacts with language processing in multiple brain regions. This occurs via visual projections to auditory, language, and multisensory brain regions. The association of auditory and visual speech signals makes the speech signal a highly “configural” percept. An important direction for the field is thus to provide ways to measure the extent to which visual speech information influences auditory processing, and likewise, assess how the unisensory components of the signal combine to form a configural/integrated percept. Numerous behavioral measures such as accuracy (e.g., percent correct, susceptibility to the “McGurk Effect”) and reaction time (RT) have been employed to assess multisensory integration ability in speech perception. On the other hand, neural based measures such as fMRI, EEG and MEG have been employed to examine the locus and or time-course of integration. The purpose of this Research Topic is to find converging behavioral and neural based assessments of audiovisual integration in speech perception. A further aim is to investigate speech recognition ability in normal hearing, hearing-impaired, and aging populations. As such, the purpose is to obtain neural measures from EEG as well as fMRI that shed light on the neural bases of multisensory processes, while connecting them to model based measures of reaction time and accuracy in the behavioral domain. In doing so, we endeavor to gain a more thorough description of the neural bases and mechanisms underlying integration in higher order processes such as speech and language recognition.

Research is suggesting that rather than our senses being independent, perception is fundamentally a multisensory experience. This handbook reviews the evidence and explores the theory of broad underlying principles that govern sensory interactions, regardless of the specific senses involved.

This volume deals with some of the association areas of the cerebral cortex and with the auditory cortex. In the first chapter, by Deepak Pandya and Edward Yeterian, the general architectural features and connections of cortical associ ation areas are considered; as these authors point out, in primates the association areas take up a considerable portion of the total cortical surface. Indeed, it is the development of the association areas that accounts for the greatest differ ences between the brains of primate and non primate species, and these areas have long been viewed as crucial in the formation of higher cognitive and be havioral functions. In the following chapter, Irving Diamond, David Fitzpatrick, and James Sprague consider the question of whether the functions of the as sociation areas depend on projections from the sensory areas of the cortex. They use the visual cortex to examine this question and show that there is a great deal of difference between species in the amount of dependence, the differences being paralleled by variations in the manner in which the geniculate and pulvinar nuclei of the thalamus project to the striate and extra striate cortical areas. One of the more interesting and perhaps least understood of the association areas is the cingulate cortex, discussed by Brent Vogt. Cingulate cortex has been linked with emotion and with affective responses to pain, and in his chapter Vogt gives an account of its cytoarchitecture, connections, and functions.

Fluency is the quintessence of effective reading. To obtain socio-economic success, fluent reading is of primordial importance and reading is considered a crucial marker of an individual’s life course. Approximately 5% of children are affected by developmental dyslexia, exhibiting inaccurate word recognition, spelling, phonological decoding, and most importantly, severely dysfluent reading, which remains as their most characterizing and persistent deficit. Unable to attain society’s literacy demands, individuals with dyslexia are at severe risk for adverse academic, economic, and psychosocial consequences. Recently, it has been posed that the development of automatic letter-speech sound (LSS) integration is critical in the acquisition of fluent reading skills, and in particular that a failure to develop automatic LSS integration results in an impairment of reading fluency. In support, neurocognitive research has suggested that the development of automatized processing of LSS associations is an essential step in the formation of a functional neural network for reading. Furthermore, both neurocognitive and behavioural studies have suggested a less efficient LSS integration in children with dyslexia than in typical readers. Finally, results from intervention studies have suggested that training LSS might be a promising approach to ameliorate dysfluent reading in children with dyslexia. Nonetheless, there is still a considerable gap of knowledge in our understanding of the mechanisms by which learning LSS associations relate to (dys)fluent reading.
