Visual search strategies, particularly regarding the importance of information from the eye area, and the ability to recognise facially expressed emotions were compared between 24 adults with Asperger syndrome and their matched controls. While wearing a head mounted eye tracker, the participants viewed 12 pairs of photos of faces. The first photo in each pair was cut up into puzzle pieces. Six of the 12 puzzle pieced photos had the eyes bisected. The second photo showed a happy, an angry and a surprised face of the same person as in the puzzle pieced photo. Differences in visual search strategies between the groups were established. Adults with Asperger syndrome had greater difficulties recognizing these basic emotions than controls. The distortion of the eye area affected the ability to identify emotions even more negatively for participants with Asperger syndrome.

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)

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’.

The influences of static and interactive dynamic facial stimuli on visual strategies in persons with Asperger syndrome / Marita FALKMER in Research in Autism Spectrum Disorders, 5-2 (April-June 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-2 (April-June 2011) . - p.935-940 Titre : The influences of static and interactive dynamic facial stimuli on visual strategies in persons with Asperger syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Marita FALKMER, Auteur ; Anna BJALLMARK, Auteur ; Matilda LARSSON, Auteur ; Torbjörn FALKMER, Auteur Année de publication : 2011 Article en page(s) : p.935-940 Langues : Anglais (eng) Mots-clés : Consistency across conditions  Eye tracking  Facial stimuli  Fixation durations  Number of fixations Index. décimale : PER Périodiques Résumé : Several studies, using eye tracking methodology, suggest that different visual strategies in persons with autism spectrum conditions, compared with controls, are applied when viewing facial stimuli. 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.
