Geurts, Hilde M; de Wit, Sanne – Autism: The International Journal of Research and Practice, 2014
Repetitive behavior is a key characteristic of autism spectrum disorders. Our aim was to investigate the hypothesis that this abnormal behavioral repetition results from a tendency to over-rely on habits at the expense of flexible, goal-directed action. Twenty-four children with autism spectrum disorders and 24 age- and gender-matched controls…

Dekker, Linda P.; Hartman, Catharina A.; van der Vegt, Esther J. M.; Verhulst, Frank C.; van Oort, Floor V. A.; Greaves-Lord, Kirstin – Autism: The International Journal of Research and Practice, 2015
Individuals with autistic traits are considered to be prone to develop psychosexual problems due to their limited social skills and insight. This study investigated the longitudinal relation between autistic traits in childhood (T1; age 10-12 years) and parent-reported psychosexual problems in early adolescence (T2; age 12-15 years). In a general…
