Abstract: Impairments in cognitive control generating deviant adaptive cognition have been proposed to account for the strong preference for repetitive behavior in autism. We examined if this preference reflects intentional deficits rather than problems in task execution in the broader autism phenotype using the Autism-Spectrum Quotient (AQ). Participants chose between two tasks differing in their relative strength by indicating first their voluntary task choice and then responding to the subsequently presented stimulus… Show more

“…This method provides an additional measure to the task-switching RTs and error rates typically studied: the choice RT to cues that invite participants to choose a task in a voluntary switching condition, or to indicate the relevant task in the instructed condition (see details below, cf. Arrington & Logan, 2005;Orr et al, 2012;Poljac, Poljac, & Yeung, 2012). Differences in speed of responding to the instructed cue (indicating which task they ought to perform) and the voluntary cue (indicating that a task choice is required) might indicate differential involvement of control processes in the two conditions.…”

“…Nevertheless, humans have difficulties to continue a reading if the colour 'red' printed in 'blue' (stroop effect), or to sort cards when the sorting criteria (i.e., shape, colour, number of symbols, etc.) changes periodically (wisconsin card sorting task) [1], [3], [11]. Furthermore, the alien limb syndrome and utilization behaviour are well known neurological disorders that show the importance of using cognitive control on top of the automatic action formation process whenever needed (cf.…”

“…[6]). The restricted and repetitive behaviour of ASD patients (like "stereotypy" or "perseveration") which is one of the key symptoms of these patients has been interpreted as a reflection of intentional deficits rather than problems in task execution [11].…”

“…Furthermore, TD individuals with more self-reported autistic traits showed a Flanker task interference pattern similar to that of diagnosed individuals, having stronger interference at higher perceptual loads (Bayliss and Kritikos 2011;Remington et al 2009). Finally, the bias many individuals with ASD show towards repetitive behaviour and the motor problems that are often observed in ASD also carry over into the general population (Poljac et al 2012;Ridley et al 2011). However, not all findings are supportive of the autism spectrum hypothesis.…”

“…With respect to studies examining the broad phenotype for social functioning, one study used both a regression and an extreme group approach (Jobe and White 2007), and three out of the seven discussed studies exclusively selected participants from the extreme ends of the distribution (Jameel et al 2014(Jameel et al , 2015Poljac et al 2013). This was also the case for 4 of the 10 cognitive, visuospatial, executive and motor function studies mentioned (Grinter et al 2009;Kunihira et al 2006;Poljac et al 2012;Stewart et al 2009) and for 9 of the 12 studies discussed in a meta-analysis specifically focused on visuospatial ability (Cribb et al 2016). Instead of using regression or a median split to include all participants, most of these studies examining the broad autism phenotype recruited several hundred participants and used extreme cut-offs or the upper and lower percentiles of these large databases to select TD individuals with respectively very high and very low AQ scores.…”
