Kadlaskar, Girija; Mao, Pin-Hsun; Iosif, Ana-Maria; Amaral, David; Wu Nordahl, Christine; Miller, Meghan – Autism: The International Journal of Research and Practice, 2023
Sensory processing differences are widely reported in autism. However, our understanding of sensory profiles in this population has been complicated due to the heterogeneous presentation of sensory symptoms. We addressed this by using latent profile analysis, allowing for the identification of more homogeneous sensory classes in a large cohort (n…

Kelly, M. P.; Reed, P. – Focus on Autism and Other Developmental Disabilities, 2021
"Stimulus over-selectivity" describes a phenomenon in which an individual responds only to a subset of the stimuli present in the environment and, thus, may restrict learning. This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of…

Poljac, Edita; Hoofs, Vincent; Princen, Myrthe M.; Poljac, Ervin – Journal of Autism and Developmental Disorders, 2017
Although behavioural rigidity belongs to the core symptoms of autism spectrum conditions, little is known about its underlying cognitive mechanisms. The current study investigated the role of intentional control mechanisms in behavioural rigidity in autism. Autistic individuals and their matched controls were instructed to repeatedly choose…

Davies, Patrick T.; Coe, Jesse L.; Hentges, Rochelle F.; Sturge-Apple, Melissa L.; Ripple, Michael T. – Developmental Psychology, 2018
This study examined children's attention biases to negative emotional stimuli as mediators of associations between interparental hostility and children's externalizing symptoms. Participants included 243 children (M[subscript age] = 4.60 years) and their parents and teachers across three annual measurement occasions. Cross-lagged latent change…

Fogelson, Noa; Shah, Mona; Scabini, Donatella; Knight, Robert T. – Brain, 2009
We investigated the role of prefrontal cortex (PFC) in local contextual processing using a combined event-related potentials and lesion approach. Local context was defined as the occurrence of a short predictive series of visual stimuli occurring before delivery of a target event. Targets were preceded by either randomized sequences of standards…
