Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The second objective is to assess the degree to which communicative difficulties stem from the core cognitive deficits faced by individuals with ADHD. Only recently has the developmental literature uncovered the relationship between cognitive skills and communicative perspective-taking. That is, children who have more proficient inhibition are better able to suppress their own perspective in order to take into account the perspective of a conversational partner (Nilsen \& Graham, 2009). Furthermore, working memory skills have been found to relate to children's ability to understand the intentions of speakers who use figurative language (e.g., Filippova \& Astington, 2008).Thus, it may be that a weakness in inhibition and working memory (over and above possible weakness in their mentalizing skills) prevents children with ADHD from using the perspective of their conversational partner during communicative interactions.
General research questions: Are adolescents with ADHD less able to appreciate the perspective of conversational partners? Does this relate to their core executive deficits?
Specific Research Questions Summary:
1. Do adolescents with ADHD show less social inference ability? Is this ability exacerbated by increased cognitive demands (e.g., working memory)?
2. Do adolescents with ADHD show less communicative perspective-taking? Is this related to their inhibitory control skills?
3. Do adolescents with ADHD overestimate the clarity of their intended messages in texts? Is this 'overestimation' more closely related to difficulties with appreciating 'common ground' when constructing text messages?
4. Do adolescents with ADHD conflate their own knowledge with that of a listener in third-person perspective tasks? Is this related to IC / WM?
Other questions that can be examined in the proposed study, but not outlined specifically here:
5. Do adolescents that show difficulty on the communicative perspective-taking tasks show worse overall social competence? (self/parent report)
6. Is the social outcome worse for girls than boys, due to the more intimate social milieu of girls compared to relatively loose social networks of adolescent boys? (e.g., Ohan \& Honston, 2007).
7. Do self-reported EF difficulties relate to actual EF performance? Do self-reported EF difficulties relate to performance on the perspective-taking tasks?
Proposed procedure:
* Adolescents who met diagnostic criteria in previous clinical/research assessment are invited to come back to SickKids to participate in research study (ages 13-17)
* Adolescent controls are tested through local high schools
Task summary:

* Texting task (similar to Kruger et al., ) (15 min)
* Story Vignette task (15 min)
Executive function tasks:
Inhibitory Control measures:
