During training, responding to one stimulus (S+) resulted in rewards whereas responding to the alternative (S−) was extinguished. Test 1 was conducted with recombinations of S+ and S− elements. In Test 2, the test stimulus to which the child responded most in Test 1 was pitched against the training S+. In Test 1, all children responded exclusively to one test probe, spuriously implying stimulus overselectivity in both populations. However, in Test 2, the typical children responded mostly to the training S+ indicating control by both S+ elements; the autistic children responded to both stimuli indicating reduced control by the second S+ element (indicating overselectivity).

Attention to emotional tone of voice in speech perception in children with autism / Patricia J. BROOKS in Research in Autism Spectrum Disorders, 7-7 (July 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-7 (July 2013) . - p.845-857 Titre : Attention to emotional tone of voice in speech perception in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Patricia J. BROOKS, Auteur ; Bertram O. PLOOG, Auteur Article en page(s) : p.845-857 Langues : Anglais (eng) Mots-clés : Affective prosody  Selective attention  Speech perception  Video game  Discrimination-choice procedure Index. décimale : PER Périodiques Résumé : A video game was developed to assess speech perception in 13 children with autism spectrum disorders (ASD) and 13 children with typical development (TYP), ages 5–17 years old. Children listened to pre-recorded sentences varying in content (e.g., “Bob parked a van” vs. “Tim shut a door”) and prosody (i.e., enthusiastic vs. grouchy tone of voice). During training, children learned to select one of two sentences differing in both content and prosody (e.g., enthusiastic “Bob parked a van” vs. grouchy “Tim shut a door”). At testing, children listened to test probes comprising re-combinations of the content and prosodic features of the training sentences. Testing indicated that both groups showed accurate discrimination of the training sentences from the re-combined test probes. However, whereas TYP children showed a preference to select the sentence with enthusiastic prosody over its grouchy counterpart, children with ASD did not. Thus, children with ASD show atypical attention to emotional tone of voice, even though they show no deficit in perceiving prosody.

Attention to prosody (intonation) and content in children with autism and in typical children using spoken sentences in a computer game / Bertram O. PLOOG in Research in Autism Spectrum Disorders, 3-3 (July-September 2009)

Nine typically developing children were also included. The children listened to pre-recorded sentences varying with respect to content (e.g., “Max ate a grape” vs. “Tom threw a ball”) and prosody (i.e., intonation of statement vs. question). During training, children learned to select one of two sentences differing in both content and prosody. At testing, children listened to stimuli consisting of recombinations of the content and prosodic features of the training stimuli. Testing performance indicated that the children with autism attended to the content and prosodic features of the training stimuli equally, whereas the children with typical development showed a clear preference for content over prosody. Both groups showed accurate discrimination of the training stimuli from the recombined test stimuli. The findings are interpreted in light of three approaches to explain the unusual attention patterns in autism: stimulus overselectivity, weak central coherence, and enhanced perceptual functioning.

Perception of the prosody and content of sentences in an unfamiliar language in children with autism spectrum disorders / Bertram O. PLOOG in Research in Autism Spectrum Disorders, 8-7 (July 2014)

Using a discrimination-choice procedure embedded in a custom-made videogame, we examined attention to these features of sentences in 15 children with ASD (ages 5 years, 5 months–18 years) and 15 age-matched typical controls (TYP). Using an unfamiliar language (German) to remove semantics, we assessed the role of meaning in promoting attention to content over prosody. As in a previous study with English sentences, TYP children attended to content to a greater extent than children with ASD while maintaining equivalent levels of discrimination based on prosody. However, in contrast to previous results, TYP children did not show a preference for enthusiastic over grouchy tone of voice, which suggests that the unfamiliar language rendered affective valence less salient. The results confirm intact perception of prosody in children with ASD, and a more selective pattern of attention to content in TYP children.

Stimulus Overselectivity Four Decades Later: A Review of the Literature and Its Implications for Current Research in Autism Spectrum Disorder / Bertram O. PLOOG in Journal of Autism and Developmental Disorders, 40-11 (November 2010)

While it is clear that overselectivity is not specific to autism spectrum disorder (ASD) and also that not all persons with ASD exhibit overselectivity, it is prevalent in ASD and has critical implications for symptoms, treatment, research, and theory. Weak Central Coherence and Enhanced Perceptual Functioning theories are briefly considered. The research areas addressed here include theory of mind, joint attention, language development, and executive function.
