Understanding indirect requests for information in high-functioning autism

Effects of Mozart-Orff parent-child music therapy among mothers and their preschool children with autism spectrum disorder: A mixed-methods randomised controlled trial

BACKGROUND

Autism spectrum disorder (ASD) negatively impacts mental health, particularly in mothers of autistic children who experience heightened stress. Applied behaviour analysis (ABA) and music therapy are recognised interventions for improving ASD symptoms. However, the specific benefits of parent-child music therapy and ABA for autistic children and their mothers remain uncertain. This study evaluated the effects of parent-child music therapy on preschool autistic children and their mothers.

METHOD

A randomised controlled trial was conducted with 100 mother-child pairs assigned to either the control group receiving ABA or the intervention group receiving both music therapy and ABA. Qualitative interviews were conducted post-intervention for 12 mothers.

RESULTS

Children in the intervention group exhibited lower scores for ASD symptoms than those in the control group. Moreover, mothers in the intervention group demonstrated reduced dysfunctional parent-child interaction, lower overall parental stress, significantly improved family functioning, and increased levels of hope compared with those in the control group. Mothers held positive views regarding music therapy.

CONCLUSIONS

Combining ABA with parent-child music therapy can alleviate ASD symptoms in children and reduce stress in mothers. Improved parent-child interaction and enhanced family functioning further support the benefits of this combined approach. Parent-child music therapy, combined with ABA demonstrated positive outcomes for autistic children, including reduced ASD symptoms, improved parent-child interaction, decreased parental stress, enhanced family functioning, and increased hope. These findings highlight the potential of incorporating music therapy as a valuable component in the comprehensive treatment of ASD.

Autistic and non-autistic adults use discourse context to determine a speaker's intention to request

The current study focuses on how autistic adults utilize context to determine whether ambiguous utterances (e.g., "I'm thirsty") are intended as indirect requests or as literal comment/questions. Two questions are addressed: (1) How do autistic adults compare to neurotypical adults in using context to interpret an utterance's intention as either literal or a request? (2) What cognitive mechanisms correlate with indirect request interpretation, and are these different for participants in each group? Twenty-six autistic and 26 neurotypical college students participated, engaging in an online experiment where they read narratives that ended with utterances open to literal or request interpretations, based on context. After each narrative, participants selected the best paraphrase of the utterance from two options, literal versus request. Following this task, participants completed two mentalizing measures (a false belief and emotion-identification task) and several executive functioning tests. The best model for predicting paraphrase choice included scores on the emotion-identification task and context as main effects, along with the interaction between both. Participants with higher emotion-identification test scores were more likely to provide correct paraphrases. Models including group as a main effect and/or interaction were not better at fitting the data, nor were any models that included executive functioning measures as main effects or interactions. Emotion-identification test scores, but not autism diagnosis, predict how adults infer whether an utterance is a request. Findings suggest that autistic adults use context similarly to neurotypical adults when interpreting requests, and that similar processes underlie performance for each group.

Children use disagreement to infer what happened

In a rapidly changing and diverse world, the ability to reason about conflicting perspectives is critical for effective communication, collaboration, and critical thinking. The current pre-registered experiments with children ages 7 to 11 years investigated the developmental foundations of this ability through a novel social reasoning paradigm and a computational approach. In the inference task, children were asked to figure out what happened based on whether two speakers agreed or disagreed in their interpretation. In the prediction task, children were provided information about what happened and asked to predict whether two speakers will agree or disagree. Together, these experiments assessed children's understanding that disagreement often results from ambiguity about what happened, and that ambiguity about what happened is often predictive of disagreement. Experiment 1 (N = 52) showed that children are more likely to infer that an ambiguous utterance occurred after learning that people disagreed (versus agreed) about what happened and found that these inferences become stronger with age. Experiment 2 (N = 110) similarly found age-related change in children's inferences and also showed that children could reason in the forward direction, predicting that an ambiguous utterance would lead to disagreement. A computational model indicated that although children's ability to predict when disagreements might arise may be critical for making the reverse inferences, it did not fully account for age-related change.

Exploring Pragmatic Deficits in Relation to Theory of Mind and Executive Functions: Evidence from Individuals with Right Hemisphere Stroke

Research investigating pragmatic deficits in individuals with right hemisphere damage focuses on identifying the potential mechanisms responsible for the nature of these impairments. Nonetheless, the presumed shared cognitive mechanisms that could account for these deficits have not yet been established through data-based evidence from lesion studies. This study aimed to examine the co-occurrence of pragmatic language deficits, Theory of Mind impairments, and executive functions while also exploring their associations with brain lesion sites. Twenty-five patients suffering from unilateral right hemisphere stroke and thirty-seven healthy participants were recruited for this study. The two groups were tested in pragmatics, Theory of Mind, and executive function tasks. Structural imaging data were also obtained for the identification of the lesion sites. The findings of this study suggest a potential convergence among the three aforementioned cognitive mechanisms. Moreover, we postulate a hypothesis for a neural circuitry for communication impairments observed in individuals with right hemisphere damage.

Language in autism: domains, profiles and co-occurring conditions

This article reviews the current knowledge state on pragmatic and structural language abilities in autism and their potential relation to extralinguistic abilities and autistic traits. The focus is on questions regarding autism language profiles with varying degrees of (selective) impairment and with respect to potential comorbidity of autism and language impairment: Is language impairment in autism the co-occurrence of two distinct conditions (comorbidity), a consequence of autism itself (no comorbidity), or one possible combination from a series of neurodevelopmental properties (dimensional approach)? As for language profiles in autism, three main groups are identified, namely, (i) verbal autistic individuals without structural language impairment, (ii) verbal autistic individuals with structural language impairment, and (iii) minimally verbal autistic individuals. However, this tripartite distinction hides enormous linguistic heterogeneity. Regarding the nature of language impairment in autism, there is currently no model of how language difficulties may interact with autism characteristics and with various extralinguistic cognitive abilities. Building such a model requires carefully designed explorations that address specific aspects of language and extralinguistic cognition. This should lead to a fundamental increase in our understanding of language impairment in autism, thereby paving the way for a substantial contribution to the question of how to best characterize neurodevelopmental disorders.

The relationships between students’ comprehension of conversational implicatures and their achievement in reading comprehension

The most important thing in effective communication is understanding not only what is said, but also why it is said. Therefore, the development of pragmatic competence in another language is essential to be able to communicate effectively. Pragmatic competence plays an important role in enabling interlocutors to work out what is intended by what is said. In this sense, special emphasis should be placed on the pragmatic aspects of language in order to enable language learners to use language appropriately. In this regard, this study aims to investigate whether there is a relationship between students’ comprehension of conversational implicatures and their achievement in reading comprehension. To this end, the data were collected from first-year 122 students at one of the private universities in northern Cyprus with different bachelor’s degrees via the Multiple-Choice Discourse Completion Test (MCDCT) and the reading test. The quantitative data were analysed by means of A Pearson Correlational Analysis, Simple Linear Regression, and Canonical Correlational Analysis. The results of the study revealed that comprehension of conversational implicatures of first-year university students is positively related to their achievement in reading comprehension. Moreover, it has been depicted that among the eight implicature types, topic change, indirect refusal, and disclosure are more related (0.855) to reading comprehension. Therefore, these three implicature types provide the most contribution to the participants’ comprehension of conversational implicatures. As it is, they are more powerful predictors of reading comprehension. In addition to these results, there is only one high positive correlation among the six reading subskills; that is between the subskill to identify ideas and opinions of the writer and the subskill to scan a text to find specific information (0.749). In the light of the findings, this study yields crucial implications for language teachers, material developers, and curriculum designers to take full advantage of these associations for promoting EFL learners’ achievement in reading and comprehension of conversational implicatures in the target language.
