• Artificial intelligence for the measurement of vocal stereotypy 

    Dufour, Marie-Michèle; Lanovaz, Marc; Cardinal, Patrick (Wiley, 2020-11-03)
    Both researchers and practitioners often rely on direct observation to measure and monitor behavior. When these behaviors are too complex or numerous to be measured in vivo, relying on direct observation using human observers increases the amount of ...
  • Assessment and treatment of stereotypy in an individual with Cornelia de Lange syndrome and deafblindness 

    Lanovaz, Marc; Rapp, John T.; Maciw, Isabella (Taylor & Francis, 2014)
    Background Several researchers have reduced engagement in stereotypy in individuals with intellectual disability and deafblindness using interventions containing a punishment component. The purpose of our study was to examine whether we could produce ...
  • Brief report : mobile technology to support parents in reducing stereotypy 

    Trudel, Lydia; Lanovaz, Marc; Préfontaine, Isabelle (Springer, 2020-09-30)
    Although behavioral interventions have been known to efectively reduce stereotypy in children with ASD, these types of interventions are not accessible to all families. In response to this issue, we evaluated the efects of the iSTIM, an iOS application ...
  • Effects of multiple interventions for reducing vocal stereotypy: Developing a sequential intervention model 

    Lanovaz, Marc; Rapp, John T.; Maciw, Isabella; Prégent-Pelletier, Émilie; Dorion, Catherine; Ferguson, Stéphanie; Saade, Sabine (Elsevier, 2014)
    Despite the availability of several interventions designed to reduce engagement in vocal stereotypy, few studies have compared two or more interventions together. Consequently, practitioners have limited amount of data to make informed decisions on ...
  • Effects of reducing stereotypy on other behaviors: a systematic review 

    Lanovaz, Marc; Robertson, Kirsty M.; Soerono, Kara; Watkins, Nicholas (Elsevier, 2013)
    Researchers have shown that high levels of stereotypy in individuals diagnosed with autism spectrum disorders were correlated with more significant impairments in social and adaptive functioning. Reducing stereotypy may thus potentially occasion an ...
  • Preliminary effects of conditioned establishing operations on stereotypy 

    Lanovaz, Marc; Rapp, John T.; Long, Ethan S.; Richling, Sarah M.; Carroll, Regina A. (Springer Verlag, 2014)
    We repeatedly paired preferred stimuli with known establishing properties and poster boards (i.e., neutral stimuli) to examine whether these poster boards would acquire the effects of a conditioned establishing operation in five children with autism. ...
  • Preliminary effects of parent-implemented behavioural interventions for stereotypy 

    Lanovaz, Marc; Rapp, John T.; Maciw, Isabella; Dorion, Catherine; Prégent-Pelletier, Émilie (Taylor & Francis, 2016)
    Objective: The purpose of our study was to replicate and extend previous research on using multicomponent behavioural interventions designed to reduce engagement in stereotypy by examining their effects when implemented by parents over several months. ...
  • Prevalence of stereotypy in individuals with developmental disabilities: a systematic review 

    Chebli, Sabine S.; Martin, Valérie; Lanovaz, Marc (Springer Verlag, 2016)
    Although many researchers have examined the prevalence of stereotypy in individuals with developmental disabilities, the results of previous studies have not been aggregated and analyzed methodically. Thus, we conducted a systematic review of studies ...
  • Salivary cortisol and stereotypy in minimally verbal children with autism : a pilot study 

    Dufour, Marie-Michèle; Lanovaz, Marc; Plusquellec, Pierrich (Springer, 2022-08-30)
    Several studies have reported conflicting results when assessing associations between stress and repetitive behaviors in individuals with autism spectrum disorder (ASD). Some factors that may have caused these discrepant results include the monitoring ...
  • Using mobile technology to reduce engagement in stereotypy : a validation of decision-making algorithms 

    Mobile technology to reduce stereotypy
    Préfontaine, Isabelle; Lanovaz, Marc; McDuff, Emeline; McHugh, Catherine; Cook, Jennifer L. (SAGE, 2017-12)
    We developed an iOS app, the iSTIM, designed to support parents of children with autism spectrum disorders (ASD) in reducing common repetitive vocal and motor behavior (i.e., stereotypy). The purpose of our study was to preliminarily test the ...
