چکیده انگلیسی

Emotional prosody perception is essential for social communication, but it is still an open issue whether children with high-function autism (HFA) exhibit any prosodic perception deficits or experience selective impairments in recognizing the prosody of positive emotions. Moreover, the associations between prosody perception, pragmatic language, and social adaptation in children with HFA have not been fully explored. This study investigated whether emotional prosody perception for words and sentences in children with HFA (n = 25, 6–11 years of age) differed from age-matched, typically developing children (TD, n = 25) when presented with an emotional prosody identification task. The Children's Communication Checklist and Vineland Adaptive Behavior Scale were used to assess pragmatic and social adaption abilities. Results show that children with HFA performed poorer than TD children in identifying happy prosody in both emotionally neutral and relevant utterances. In contrast, children with HFA did not exhibit any deficits in identifying sad and angry prosody. Results of correlation analyses revealed a positive association between happy prosody identification and pragmatic function. The findings indicate that school-aged children with HFA experience difficulties in recognizing happy prosody, and that this limitation in prosody perception is associated with their pragmatic and social adaption performances.

مقدمه انگلیسی

Social communication deficit is one of the core symptoms in children with autistic spectrum disorder (DSM-V, 2013). The ability to correctly and effectively recognize a speaker's emotions from their utterances is essential to social communication (Lindner and Rosén, 2006 and Shriberg et al., 2001). In addition to semantic meaning, emotional prosody of utterances also manifests a speaker's emotions during social communication. Deficits in producing appropriate emotional prosody in storytelling and conversations are well documented for children with autism (e.g., DSM-V, 2013), but it is still an open issue whether perceptual deficits in emotional prosody play any role in precipitating these deficits in producing intact emotional prosody. 1.1. Emotional prosody perception in high function autism Prosody is a linguistic term that includes intonation, stress, and rhythm (McCann, Peppé, Gibbon, O’Hare, & Rutherford, 2007). It plays an important role in linguistic functions as well as in emotional expression and comprehension (Lindner and Rosén, 2006 and Paul et al., 2005a). Deficits in prosody perception might result in atypical prosody production in autism, and also associate with difficulties in decoding emotional signals during social communication (Paul, Augustyn, et al., 2005). During social interactions, the ability to integrate emotional prosody and emotional semantics of a speaker's utterances is crucial to understanding the emotional state and communicative intentions of the speaker as it allows the listener to reciprocate with appropriate responses. Thus, the ability to comprehend emotional prosody in speech is a critical function of human social life (Wittfoth et al., 2010). Many studies have examined autistic children's abilities to recognize emotions through facial expressions; however, relatively few studies have been conducted to examine autistic children's abilities to understand emotions through prosody (Lindner and Rosén, 2006 and McCann and Peppé, 2003). Further, while there is extensive evidence in the literature of impairment in the expressive prosodic abilities of autistic individuals, the state of receptive prosodic abilities has been neglected (Le Sourn-Bissaoui et al., 2013 and McCann and Peppé, 2003). Among studies on prosody perception in adults, adolescents, or children with high-function autism (HFA) or Asperger syndrome (AS), findings of deficits in prosody perception have been equivocal. In the past decade, many studies have reported that adults or children with autism experienced difficulties in using emotional prosody to identify the emotions of others (Golan et al., 2007, Hubbard and Trauner, 2007, Järvinen-Pasley et al., 2008, Lindner and Rosén, 2006, McCann et al., 2007, Peppé et al., 2007 and Rutherford et al., 2002). In contrast, several studies have reported that the emotional prosody perception in autistic individuals is similar to that in normal controls (Brennand et al., 2011, Brooks and Ploog, 2013, Chevallier et al., 2011, Grossman et al., 2010 and Paul et al., 2005a). Therefore, it remains an open issue whether autistic children exhibit any difficulties in recognizing emotions through speech prosody. 1.2. Methodological and age differences in previous studies Inconsistent findings may occur as a consequence of small participant sample sizes (Hubbard and Trauner, 2007 and Lindner and Rosén, 2006). In addition, the use of relatively large age ranges, e.g., from early childhood to adolescence, make it difficult to compare results between different studies to determine whether people with autism show any developmental differences in prosodic processing at certain ages (Brooks and Ploog, 2013, Golan et al., 2007, Grossman and Tager-Flusberg, 2012, Grossman et al., 2010, Hubbard and Trauner, 2007 and Järvinen-Pasley et al., 2008). The ability to perceive emotional prosody starts from infancy and continues to develop during middle childhood. Sakkalou and Gattis (2012) showed that 14- to 18-month-old infants infer the intentions of other people using prosodic cues. Sensitivity to emotional prosody continues to improve in typically developing (TD) school-aged children. In a study by Friend and Bryant (2000), TD children aged 4, 7, and 10 were presented with utterances containing semantic content of positive or negative emotion in combination with happy or angry prosody, and asked to judge whether the speaker was happy or angry. Their results showed that 4- and 7-year-old children weighted semantic meaning more than emotional prosody, whereas 10-year-old children valued prosodic information more than semantic meaning. Another study, which compared the relative contribution of emotional prosody versus semantic content in judging a speaker's emotion, found that adults relied exclusively on prosody, whereas 4-year-old children responded primarily to semantic content (Morton & Trehub, 2001). These studies showed a developmental trend where children between 5 and 10 years of age gradually reduced their reliance on the semantic content of utterances to identify emotions. In other words, emotional prosody sensitivity improves in elementary school-aged children; this period is critical for the development of relative weighting between prosody and semantic content in emotion identification. Thus, assessing emotional prosody perception in elementary school-aged children with HFA would be essential to determine whether children with HFA exhibit any emotional prosody perception deficits when typically developing children are still developing their emotional prosody perception during the middle childhood. The variety of emotional prosody tasks employed in previous studies is another reason for inconsistent findings (Golan et al., 2007). Previous studies have presented emotional prosody to people with autism in different linguistic units, such as words and sentences. In addition to stimulus duration, these stimuli also varied in many aspects, such as sufficiency of contextual information, that would influence emotion identification (Paulmann and Pell, 2010 and Peppé et al., 2007). For example, the profiling elements of prosody in speech-communication (PEPS-C) test requires children to distinguish a food item that a person likes or dislikes, based on the emotional prosody of a single word ( Peppé et al., 2007). Studies adopting the PEPS-C to assess emotional prosody perception in children with HFA have demonstrated impairments in this population ( McCann et al., 2007 and Peppé et al., 2007). In contrast, studies presenting sentences as stimuli to assess emotional prosody perception in children with HFA have reported that it is similar to that in TD children ( Bertrand and Priego-Valverde, 2011, Chevallier et al., 2011, Grossman et al., 2010 and Paul et al., 2005a). Further, studies have also utilized variations in emotional semantics of speech stimuli, i.e., using stimuli with either emotionally neutral content (e.g., fruit name or I have a pencil) or emotionally relevant content (e.g., hate or I am very glad to see you). When a listener identifies emotions from speech stimuli, emotionally neutral and emotionally relevant utterances provide different emotional semantic cues that require different levels of cognitive processing (e.g., execution function). For emotionally neutral utterances, speech prosody would be the only valid cue used to identify emotions. In contrast, for emotionally relevant utterances, both semantic and prosodic cues are valid cues to identify emotions. When both cues are incongruent in recognizing emotions, for instance when the word happy is presented with the sad prosody, the processing of cognitive inhibition is mobilized to correctly recognize emotions through emotional prosody. Thus, variation in the stimuli used by studies on emotional prosody perception in children with HFA—some studies using only emotionally neutral stimuli ( Grossman and Tager-Flusberg, 2012, Hubbard and Trauner, 2007, Järvinen-Pasley et al., 2008 and McCann et al., 2007), some studies using only emotionally relevant stimuli ( Golan et al., 2007 and Rutherford et al., 2002), and some studies using a mixture ( Le Sourn-Bissaoui et al., 2013 and Singh and Harrow, 2014)—might be another reason for inconsistent findings. 1.3. The relationships between emotional prosody, pragmatics, and social adaptation Atypical prosody perception may explain social communication deficits in children with autism (Shriberg et al., 2001). Pragmatic impairment in social communication might be defined as a mismatch between language and the situation in which it is used, making the language inappropriate to situational demands (Vonden & Lord, 1991). People with pragmatic impairment experience difficulties with using verbal and non-verbal language. Pragmatic deficits are specifically and universally impaired in autism (Young, Diehl, Morris, Hyman, & Bennetto, 2005), and the ability to identify emotional intonation in utterances is essential to pragmatics and social communication (O’Connor, 2012 and Wilson and Wharton, 2006). However, only few studies have examined the relationship between emotional prosody perception and pragmatic function in children with HFA (McCann et al., 2007, Paul et al., 2005b, Volden et al., 2009 and Wang et al., 2006). In brief, the relationships between prosody perception, pragmatics, and social adaptation have rarely been explored in children with autism. Therefore, this study also attempted to assess the relationship between emotional prosody perception and linguistic pragmatics in children with HFA. 1.4. Specific aims To control the effects of methodological differences on assessing prosody perception in children with HFA, both words and short sentences were used in this study; further, these speech stimuli also varied in their emotional meaning and prosody. This design would lead to a better understanding of emotional prosody perception in elementary school-aged children with HFA. This study had two goals. First, it aimed to investigate whether school-aged children with HFA were less accurate than TD children in using emotional prosody information to judge emotions when emotionally neutral and emotionally relevant stimuli were presented in words and short sentences. If children with HFA exhibited atypical emotional prosody perception, then they were anticipated to be less accurate than TD children in judging emotions. The other goal of this study was to assess the association between emotional prosody perception and social communication skills in children with HFA. If deficits in emotional prosody perception adversely affected social interaction skills in children with HFA, reduced perceptual performance was expected to associate with poor social interaction skills.
