Lim, Yi Huey; Lee, Hoe C.; Falkmer, Torbjörn; Allison, Garry T.; Tan, Tele; Lee, Wee Lih; Morris, Susan L. – Journal of Autism and Developmental Disorders, 2019
Sensory processing difficulties affect the development of sensorimotor skills in individuals with autism spectrum disorder (ASD). However, the effect of sensory information on postural control is unclear in the ASD adult population. The present study examined the effect of visual information on postural control as well as the attentional demands…

Krüger, Britta; Kaletsch, Morten; Pilgramm, Sebastian; Schwippert, Sven-Sören; Hennig, Jürgen; Stark, Rudolf; Lis, Stefanie; Gallhofer, Bernd; Sammer, Gebhard; Zentgraf, Karen; Munzert, Jörn – Journal of Autism and Developmental Disorders, 2018
One major characteristic of autism spectrum disorder (ASD) is problems with social interaction and communication. The present study explored ASD-related alterations in perceiving emotions expressed via body movements. 16 participants with ASD and 16 healthy controls observed video scenes of human interactions conveyed by point-light displays. They…

Hayes, Spencer J.; Andrew, Matthew; Elliott, Digby; Gowen, Emma; Bennett, Simon J. – Journal of Autism and Developmental Disorders, 2016
We examined whether adults with autism had difficulty imitating atypical biological kinematics. To reduce the impact that higher-order processes have on imitation we used a non-human agent model to control social attention, and removed end-state target goals in half of the trials to minimise goal-directed attention. Findings showed that only…

South, Mikle; Taylor, Katherine M.; Newton, Tiffani; Christensen, Megan; Jamison, Nathan K.; Chamberlain, Paul; Johnston, Oliver; Crowley, Michael J.; Higley, J. Dee – Journal of Autism and Developmental Disorders, 2017
We measured skin conductance response (SCR) to escalating levels of a direct social threat from a novel, ecologically-relevant experimental paradigm, the Intruder Threat Task. We simultaneously evaluated the contribution of social symptom severity and behavioral movement. Children with AS group showed less psychophysiological reactivity to social…

Centelles, Laurie; Assaiante, Christine; Etchegoyhen, Katallin; Bouvard, Manuel; Schmitz, Christina – Journal of Autism and Developmental Disorders, 2013
Two studies investigated whether typically developing children (TD) and children with autism spectrum disorders (ASD) were able to decide whether two characters were communicating or not on the basis of point-light displays. Point-lights portrayed actors engaged or not in a social interaction. In study 1, TD children (4-10 years old; n = 36)…

Mostert-Kerckhoffs, Mandy A.; Staal, Wouter G.; Houben, Renske H.; de Jonge, Maretha V. – Journal of Autism and Developmental Disorders, 2015
Cognitive control dysfunctions, like inhibitory and attentional flexibility deficits are assumed to underlie repetitive behavior in individuals with autism spectrum disorders (ASD). In the present study, prepotent response inhibition and attentional flexibility were examined in 64 high-functioning individuals with ASD and 53 control participants.…

Annaz, Dagmara; Campbell, Ruth; Coleman, Mike; Milne, Elizabeth; Swettenham, John – Journal of Autism and Developmental Disorders, 2012
Preferential attention to biological motion can be seen in typically developing infants in the first few days of life and is thought to be an important precursor in the development of social communication. We examined whether children with autism spectrum disorder (ASD) aged 3-7 years preferentially attend to point-light displays depicting…

Wild, Kelly S.; Poliakoff, Ellen; Jerrison, Andrew; Gowen, Emma – Journal of Autism and Developmental Disorders, 2012
To investigate how people with Autism are affected by the presence of goals during imitation, we conducted a study to measure movement kinematics and eye movements during the imitation of goal-directed and goal-less hand movements. Our results showed that a control group imitated changes in movement kinematics and increased the level that they…

Rutherford, M. D.; Troje, Nikolaus F. – Journal of Autism and Developmental Disorders, 2012
Biological motion is easily perceived by neurotypical observers when encoded in point-light displays. Some but not all relevant research shows significant deficits in biological motion perception among those with ASD, especially with respect to emotional displays. We tested adults with and without ASD on the perception of masked biological motion…

Longuet, Sophie; Ferrel-Chapus, Carole; Oreve, Marie-Joelle; Chamot, Jean-Marc; Vernazza-Martin, Sylvie – Journal of Autism and Developmental Disorders, 2012
This article focuses on the impact of intentionality on goal directed locomotion in healthy and autistic children. Closely linked with emotions and motivation, it is directly connected with movement planning. Is planning only preserved when the goal of the action appears motivating for healthy and autistic children? Is movement programming similar…

Rodgers, J.; Glod, M.; Connolly, B.; McConachie, H. – Journal of Autism and Developmental Disorders, 2012
Children with Autism Spectrum Disorder are vulnerable to anxiety. Repetitive behaviours are a core feature of Autism Spectrum Disorder (ASD) and have been associated with anxiety. This study examined repetitive behaviours and anxiety in two groups of children with autism spectrum disorder, those with high anxiety and those with lower levels of…

Laine, France; Rauzy, Stephane; Tardif, Carole; Gepner, Bruno – Journal of Autism and Developmental Disorders, 2011
Imitation deficits observed among individuals with autism could be partly explained by the excessive speed of biological movements to be perceived and then reproduced. Along with this assumption, slowing down the speed of presentation of these movements might improve their imitative performances. To test this hypothesis, 19 children with autism,…

McAleer, Phil; Kay, Jim W.; Pollick, Frank E.; Rutherford, M. D. – Journal of Autism and Developmental Disorders, 2011
The perception of intent in Autism Spectrum Disorders (ASD) often relies on synthetic animacy displays. This study tests intention perception in ASD via animacy stimuli derived from human motion. Using a forced choice task, 28 participants (14 ASDs; 14 age and verbal-I.Q. matched controls) categorized displays of Chasing, Fighting, Flirting,…

Congiu, Sara; Schlottmann, Anne; Ray, Elizabeth – Journal of Autism and Developmental Disorders, 2010
We investigated perception of social and physical causality and animacy in simple motion events, for high-functioning children with autism (CA = 13, VMA = 9.6). Children matched 14 different animations to pictures showing physical, social or non-causality. In contrast to previous work, children with autism performed at a high level similar to…

Nazarali, Natasha; Glazebrook, Cheryl M.; Elliott, Digby – Journal of Autism and Developmental Disorders, 2009
Two experiments explored how individuals with and without autism plan and reprogram movements. Participants were given partial or complete information regarding the location of the upcoming manual movement. In Experiment 1, direct information specified the hand or direction of the upcoming movement. These results replicated previous reports that…
