Galigani, Mattia; Fossataro, Carlotta; Gindri, Patrizia; Conson, Massimiliano; Garbarini, Francesca – Journal of Autism and Developmental Disorders, 2022
Individuals with autism spectrum conditions (ASC) are less susceptible to multisensory delusions, such as rubber hand illusion (RHI). Here, we investigate whether a monochannel variant of RHI is more effective in inducing an illusory feeling of ownership in ASC. To this aim, we exploit a non-visual variant of the RHI that, excluding vision,…

Charbonneau, Geneviève; Bertone, Armando; Véronneau, Marie; Girard, Simon; Pelland, Maxime; Mottron, Laurent; Lepore, Franco; Collignon, Olivier – Journal of Autism and Developmental Disorders, 2020
Although impairment in sensory integration is suggested in the autism spectrum (AS), empirical evidences remain equivocal. We assessed the integration of low-level visual and tactile information within and across modalities in AS and typically developing (TD) individuals. TD individuals demonstrated increased redundancy gain for cross-modal…

Kyriacou, Chrysovalanto; Forrester-Jones, Rachel; Triantafyllopoulou, Paraskevi – Journal of Autism and Developmental Disorders, 2023
Tactile defensiveness in autistic individuals is the least investigated sensory modality. The current multi-component, explorative study aimed to understand the experiences of ten autistic adults regarding tactile defensiveness and fabrics, using semi-structured, one-to-one interviews. Participants were asked to discuss the effects of seven…

Magdalini Asaridou; Ericka L. Wodka; Richard A. E. Edden; Stewart H. Mostofsky; Nicolaas A. J. Puts; Jason L. He – Journal of Autism and Developmental Disorders, 2024
Sensory differences are highly prevalent in autistic individuals. However, few studies have compared their presentation between autistic males and autistic females. We used psychophysics to assess and compare tactile perceptual sensitivity between autistic and non-autistic boys and girls aged between 8 and 12 years of age. While there were…

Wada, Makoto; Umesawa, Yumi; Sano, Misako; Tajima, Seiki; Kumagaya, Shinichiro; Miyazaki, Makoto – Journal of Autism and Developmental Disorders, 2023
Previous psychophysical studies reported a positive aftereffect in tactile temporal order judgments, which can be explained by the Bayesian estimation model ('Bayesian calibration'). We investigated the relationship between Bayesian calibration and autistic traits in participants with typical development (TD) and autism spectrum disorder (ASD).…

Espenhahn, Svenja; Godfrey, Kate J.; Kaur, Sakshi; McMorris, Carly; Murias, Kara; Tommerdahl, Mark; Bray, Signe; Harris, Ashley D. – Journal of Autism and Developmental Disorders, 2023
We assessed different aspects of tactile perception in young children (3-6 years) with autism. Autistic and neurotypical children completed vibrotactile tasks assessing reaction time, amplitude discrimination (sequential and simultaneous) and temporal discrimination (temporal order judgment and duration discrimination). Autistic children had…

Jussila, K.; Junttila, M.; Kielinen, M.; Ebeling, H.; Joskitt, L.; Moilanen, I.; Mattila, M.-L. – Journal of Autism and Developmental Disorders, 2020
Sensory abnormalities (SAs) are recognized features in Autism Spectrum Disorder (ASD), and a relationship between SAs and ASD traits is also suggested in general population. Our aims were to estimate the prevalence of SAs in three different settings, and to study the association between SAs and quantitative autism traits (QAT) using the Autism…

Penton, Tegan; Bowling, Natalie; Vafeiadou, Aikaterini; Hammond, Claudia; Bird, Geoffrey; Banissy, Michael J. – Journal of Autism and Developmental Disorders, 2023
Unemployment and underemployment have consistently been shown to be higher in autistic adults relative to non-autistic adults. This may be due, in part, to a lack of workplace accommodations being made for autistic people. One factor that may contribute to employment inequalities in autistic people is differences in attitudes towards interpersonal…

Kumazaki, Hirokazu; Sumioka, Hidenobu; Muramatsu, Taro; Yoshikawa, Yuichiro; Shimaya, Jiro; Iwanaga, Ryoichiro; Ishiguro, Hiroshi; Sumiyoshi, Tomiki; Mimura, Masaru – Journal of Autism and Developmental Disorders, 2022
Sensory overresponsivity (SOR) emerges before anxiety and positively predicts subsequent increasing levels of anxiety in individuals with autism spectrum disorder (ASD). Sensory seeking behavior occurs as compensation for SOR, and individuals may seek sensory input in one sensory domain to compensate for SOR. Tactile seeking behavior is sufficient…

McKernan, Elizabeth P.; Wu, Ying; Russo, Natalie – Journal of Autism and Developmental Disorders, 2020
Previous studies have suggested that sensory overresponsivity in youth with autism spectrum disorder (ASD) may be due to a failure to habituate to stimuli. We examined the relationship between performance on three tactile psychophysical tasks and the construct of sensory overresponsivity in children with and without ASD. Sensory overresponsivity…

Poole, Daniel; Gowen, Emma; Warren, Paul A.; Poliakoff, Ellen – Journal of Autism and Developmental Disorders, 2017
Previous studies have indicated that visual-auditory temporal acuity is reduced in children with autism spectrum conditions (ASC) in comparison to neurotypicals. In the present study we investigated temporal acuity for all possible bimodal pairings of visual, tactile and auditory information in adults with ASC (n = 18) and a matched control group…

Bryant, Lauren K.; Woynaroski, Tiffany G.; Wallace, Mark T.; Cascio, Carissa J. – Journal of Autism and Developmental Disorders, 2019
Atypical responses to tactile stimulation have been linked to core domains of dysfunction in individuals with autism spectrum disorder (ASD) and phenotypic traits associated with ASD in neurotypical individuals. We investigated (a) the extent to which two psychophysically derived measures of tactile sensitivity--detection threshold and dynamic…

Kadlaskar, Girija; Seidl, Amanda; Tager-Flusberg, Helen; Nelson, Charles A.; Keehn, Brandon – Journal of Autism and Developmental Disorders, 2020
Multimodal communication may facilitate attention in infants. This study examined the presentation of caregiver touch-only and touch + speech input to 12-month-olds at high (HRA) and low risk for ASD. Findings indicated that, although both groups received a greater number of touch + speech bouts compared to touch-only bouts, the duration of…

Ide, Masakazu; Yaguchi, Ayako; Sano, Misako; Fukatsu, Reiko; Wada, Makoto – Journal of Autism and Developmental Disorders, 2019
Many individuals with autism spectrum disorder (ASD) have symptoms of sensory hypersensitivity. Several studies have shown high individual variations in temporal processing of tactile stimuli. We hypothesized that these individual differences are linked to differences in hyper-reactivity among individuals with ASD. Participants performed two tasks…

Kadlaskar, Girija; Seidl, Amanda; Tager-Flusberg, Helen; Nelson, Charles A.; Keehn, Brandon – Journal of Autism and Developmental Disorders, 2019
Atypical response to tactile input is associated with greater socio-communicative impairments in individuals with autism spectrum disorder (ASD). The current study examined overt orienting to caregiver-initiated touch in 12-month-olds at high risk for ASD (HRA) with (HRA+) and without (HRA-) a later diagnosis of ASD compared to low-risk comparison…
