Our exploratory research aims at suggesting design principles for educational software dedicated to people with high functioning autism. In order to explore the efficiency of educational games, we developed an experimental protocol to study the influence of the specific constraints of the learning areas as well as Human Computer Interface modalities. We designed computer games that were tested with 10 teenagers diagnosed with high functioning autism, during 13 sessions, at the rate of one session per week. Participants’ skills were assessed (...) before and after a training period. A group of 10 typical children matched on academic level also took part in the experiment. A software platform was developed to manage interface modalities and log users’ actions. Moreover, we annotated video recordings of two sessions. Results underline the influence of the task and interface modalities on executive functions. (shrink)

Background: Individuals with Autism Spectrum Disorder (ASD) have pronounced difficulties in attending to relevant visual information during social interactions. Method: We designed and evaluated the feasibility of a novel method to train this ability, by exposing participants to virtual human characters displayed on a screen which was entirely blurred, except for a gaze-contingent viewing window that followed participants’ eyes direction. The goal was to incite participants to direct their gaze towards the facial expressions of the virtual characters. Twenty-one adolescents with (...) ASD who attended ordinary school were randomized to either an experimental group, who was trained during a month and a half, or to a control group. Social communicative abilities were assessed during pre, post and follow-up tests. Results: After training, the experimental group showed significantly more interest in facial expressions on a test which involved understanding a dialogue. Significant differences were not found for the other tests used. Conclusions: This outcome suggests that the training method fostered participants’ awareness of the relevance of facial expressions.

This study investigates a specific aspect of joint attention, that is, the emergence of the sense that one is leading the attentional focus of others. Thirty participants were placed in front of two avatars and had to pay attention to objects that were also attended to by the avatars. Unbeknownst to the participant, the avatars’ gaze orientations were alternately controlled by the participant’s eyes. Eye-tracking data were collected and participants were enquired about their experience to account for their sense of (...) agency. Only five participants noticed that the avatars were following their gaze. The 25 participants who remained unaware that they controlled the avatars nevertheless modified their gazing behavior with an increase in direct gaze toward one of the avatars. This outcome highlights a dissociation between an implicit feeling that a change occurred and the explicit awareness of being the cause of this change. (shrink)

ContextBehavioral observation scales are important for understanding and assessing social skills. In the context of collaborative problem-solving skills, considered essential in the 21st century, there are no validated scales in French that can be adapted to different CPS tasks. The aim of this study is to adapt and validate, by annotating a new video corpus of dyadic interactions that we have collected, two observational scales allowing us to qualitatively assess CPS skills: the Social Performance Rating Scale and the Social Skills (...) of Collaboration Scale.MethodThe construct validity of these two scales was assessed by exploratory factor analysis and inter-item correlations. We also checked inter-judge agreement using inter-class correlation coefficients. Internal consistency was determined using Cronbach’s alpha and convergent and divergent validity by assessing correlations between the two scales and measures of depression and alexithymia. Finally, the discriminative properties of the two scales were analyzed by comparing the scores obtained by a group of anxious individuals and a non-anxious control group.ResultsThe results show that our two scales have excellent inter-item correlations. Internal consistency is excellent. Inter-rater agreement ranged from moderate to high. Finally, convergent validity was significant with the alexithymia scale, as was divergent validity with the depression scale. Anxious individuals had lower scores on both scales than non-anxious individuals.ConclusionBoth scales show good psychometric properties for assessing social skills relevant to different collaborative tasks. They also identify individuals with difficulties in social interaction. Thus, they could allow monitoring the effectiveness of training social skills useful in CPS. (shrink)
