The present thesis investigated processing of words and speech prosody in school-aged typically developed children and two groups of children with ASD: those with accompanying language impairments and those with no accompanying language impairments. To this end, auditory event-related potentials (ERPs) were recorded for a Finnish word uttered with...

Objective: The present study explored the processing of emotional speech prosody in school-aged children with autism spectrum disorders (ASD) but without marked language impairments (children with ASD [no LI]). Methods: The mismatch negativity (MMN)/the late discriminative negativity (LDN), reflecting pre-attentive auditory discrimination proces...

The present study addressed processing of emotional prosodic changes (sad, scornful and commanding) in natural word stimuli in typically developed school-aged children and in children with ASD and lang...

Speech prosody conveys information about important aspects of communication: the meaning of the sentence and the emotional state or intention of the speaker. The present study addressed processing of emotional prosodic changes in natural speech stimuli in school-age children (mean age 10years) by recording the electroencephalogram, facial electromy...

The events in the external environment often have a number of multisensory features such as pitch and form. For integrated percepts of objects and events, crossmodal p...
