“…A lack of auditory sensitivity for tones and syllables has been reported in children with AS and ASD (Simon, 1975;Parisse, 1999;Jansson-Verkasalo et al, 2005. ) In the present study, auditory stimuli were presented with two opposite emotional moods: tender and angry (commanding) way.…”

Many people with the diagnosis of Asperger syndrome (AS) show poorly developed skills in understanding emotional messages. The present study addressed discrimination of speech prosody in children with AS at neurophysiological level. Detection of affective prosody was investigated in one-word utterances as indexed by the N1 and the mismatch negativity (MMN) of auditory event-related potentials (ERPs). Data from fourteen boys with AS were compared with those for thirteen typically developed boys. These results suggest atypical neural responses to affective prosody in children with AS and their fathers, especially over the RH, and that this impairment can already be seen at low-level information processes. Our results provide evidence for familial patterns of abnormal auditory brain reactions to prosodic features of speech.

Similarly, research into autism has embraced three possible arousal dysfunctions: underarousal (Rimland, 1964), overarousal (Hutt, Hutt, Lee, & Ounsted, 1964), and perceptual inconstancy or faulty modulation of arousal (Ornitz & Ritvo, 1968).…”

“…Although the behavioral handicaps of autistic children argue for a central, not a brainstem, defect, Simon (1975) has pointed out that lesions of the brainstem auditory nuclei could, without causing deafness, interfere with a child's ability to discriminate certain acoustic gestures of speech signals and thus impede normal language development. More recently, Tanguay and Edwards (1982) have suggested that the dysfunction of neural systems in the brainstem occurring during a critical phase of early postnatal development might act directly as neuropathological agents adversely influencing the developing forebrain by disrupting its auditory input.…”

Electrodermal activity to auditory stimuli in autistic, retarded, and normal children

Electrodermal activity to auditory stimuli was compared in 20 autistic children and their matched retarded and normal controls (N = 80). The autistic children were virtually indistinguishable in individual features of electrodermal activity from controls when both chronological and mental age comparisons were accounted for. When patterns of activity were considered globally, both autistic and retarded children could be distinguished from one another and from normal controls. However, in some respects autistic and same-aged normal children were alike--both showed sensitization to 70-dB tones and both had a higher incidence of children with larger left- than right-hand responses, interpreted as evidence of focused attention under left hemisphere control.

“…Although echolalia is not usually thought of as serving a communicative function, autistic echolalia may acquire some idiosyncratic, symbolic meaning (Howlin, 1980). The stress, pitch and intonation of autistic speech are abnormal (Simon, 1975) and autistic echolalic utterances frequently have pronomial reversal. The autistic child cannot extract essential morphemic components from the speech of others, but repeats the whole phrase in a parrot-like manner, as if there were no grasp of the meaning of the echoed utterance.…”
