The importance of the eye area in face identification abilities and visual search strategies in persons with Asperger syndrome / Marita FALKMER in Research in Autism Spectrum Disorders, 4-4 (October-December 2010)
[article]
Titre : The importance of the eye area in face identification abilities and visual search strategies in persons with Asperger syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Marita FALKMER, Auteur ; Matilda LARSSON, Auteur ; Anna BJALLMARK, Auteur ; Torbjörn FALKMER, Auteur Année de publication : 2010 Article en page(s) : p.724-730 Langues : Anglais (eng) Mots-clés : Eye-tracking Face-information-triangle Face-recognition Fixation-durations Fixation-patterns Social-development Index. décimale : PER Périodiques Résumé : Partly claimed to explain social difficulties observed in people with Asperger syndrome, face identification and visual search strategies become important. Previous research findings are, however, disparate. In order to explore face identification abilities and visual search strategies, with special focus on the importance of the eye area, 24 adults with Asperger syndrome and matched controls viewed puzzle pieced photos of faces, in order to identify them as one of three intact photos of persons. Every second puzzle pieced photo had the eyes distorted. Fixation patterns were measured by an eye tracker. Adults with Asperger syndrome had greater difficulties in identifying faces than controls. However, the entire face identification superiority in controls was found in the condition when the eyes were distorted supporting that adults with Aspergers syndrome do use the eye region to a great extent in face identification. The visual search strategies in controls were more effective and relied on the use of the ‘face information triangle’, i.e. the two eyes and the mouth, while adults with Asperger syndrome had more fixations on other parts of the face, both when obtaining information and during the identification part, suggesting a less effective use of the ‘face information triangle’.

Titre : The influence of static versus naturalistic stimuli on face processing in children with and without Asperger syndrome or high-functioning autism Type de document : Texte imprimé et/ou numérique Auteurs : Chiara HORLIN, Auteur ; Marita FALKMER, Auteur ; Patrick FITZGERALD, Auteur ; Denise LEUNG, Auteur ; Anna ORDQVIST, Auteur ; Torbjörn FALKMER, Auteur Article en page(s) : p.1617-1624 Langues : Anglais (eng) Mots-clés : Face processing ASD Eye-tracking Dynamic Index. décimale : PER Périodiques Résumé : Abstract Questions regarding the use of static or dynamic facial stimuli in experimental studies investigating facial processing of individuals with AS/HFA raises issues of both ecological validity and the applicability of experimental findings to clinical or everyday practice. Children with and without AS/HFA (n = 38) were fitted with a head-mounted eye-tracker and exposed to either static or interactive dynamic facial stimuli. Average fixation duration, the proportion of fixations in areas of interest and a comparative index that was independent of differences in presentation length between stimuli types were calculated. Visual scanning patterns of individuals with AS/HFA were not affected by stimuli type. However, control participants exhibited different scanning patterns between dynamic and static stimuli for certain regions of the face. Visual scanning patterns in children with AS/HFA are consistent regardless of the stimuli being a static photo or dynamic in the form of a real face. Hence, information from experimental studies with static photos of faces provide information that is valid and can be generalised to “real world” interactions.

Most eye tracking studies are, however, made in laboratory settings with either static (photos) or non-interactive dynamic stimuli, such as video clips. Whether or not these results are transferable to a “real world” dialogue situation remains unclear. In order to examine the consistency of visual strategies across conditions, a comparison of two static conditions and an interactive dynamic “real world” condition, in 15 adults with Asperger syndrome and 15 matched controls, was made using an eye tracker. The static stimuli consisted of colour photos of faces, while a dialogue between the participants and the test leader created the interactive dynamic condition. A within-group comparison showed that people with AS, and their matched controls, displayed a high degree of stability in visual strategies when viewing faces, regardless of the facial stimuli being static or real, as in the interactive dynamic condition. The consistency in visual strategies within the participants suggests that results from studies with static facial stimuli provide important information on individual visual strategies that may be generalized to “real world” situations.

Titre : Viewpoints on what is important to maintain relationship satisfaction in couples raising a child with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Angela SIM, Auteur ; Sofi FRISTEDT, Auteur ; Reinie CORDIER, Auteur ; Sharmila VAZ, Auteur ; Rebecca KUZMINSKI, Auteur ; Torbjörn FALKMER, Auteur Article en page(s) : p.1-13 Langues : Anglais (eng) Mots-clés : Conflict resolution Communication Dyadic coping Marriage Partnership Strengths Teamwork Index. décimale : PER Périodiques Résumé : Background Despite the challenges associated with raising a child with autism spectrum disorder (ASD), many couples maintain satisfying relationships. However, it is not clear which factors couples prioritise as most important to this positive adaptation. Methods This study used Q-methodology to explore the viewpoints on factors most important to maintaining relationship satisfaction from the perspective of those experiencing it. Data from 43 caregivers raising a child with ASD were analysed using by-person varimax rotation factor analysis. Results Two key viewpoints were identified: 1) Building effective communication through openness, honesty and conflict resolution, and 2) Building a strong partnership by sharing parenting responsibilities. Conclusion Couples should be supported to strengthen communication processes and work in partnership to raise their child with ASD through family-centred interventions aimed at promoting relationship satisfaction.

Titre : Visual search strategies during facial recognition in children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Matthew A. ALBRECHT, Auteur ; Jonathan K. FOSTER, Auteur ; Annette V. JOOSTEN, Auteur ; Marita FALKMER, Auteur ; Julia S. Y. TANG, Auteur ; Denise LEUNG, Auteur ; Anna ORDQVIST, Auteur ; Torbjörn FALKMER, Auteur Article en page(s) : p.559-569 Mots-clés : Face recognition Eye-tracking Developmental Visual search Index. décimale : PER Périodiques Résumé : Facial recognition is a complex skill necessary for successful human interpersonal and social interactions. Given that the most prevalent disorder of social interaction is autism spectrum disorder (ASD), a number of studies have investigated and found impaired facial recognition abilities in people with ASD. Further, this impairment may be critically involved in mediating the deficits in interpersonal and social interactions in people with ASD. We sought to address the question of whether face processing is impaired in children with ASD in the current study. While there were a number of differences in visual search behaviours between the 19 children with ASD and the 15 controls, this did not manifest in deficits in facial recognition accuracy. In addition, there were notable differences with respect to eye fixation behaviours and recognition accuracy in this study compared to the findings in a previous similar study conducted in adults with ASD. These differences suggest a performance enhancing developmental trajectory in facial processing in controls that may not be present in individuals with ASD.
