Abstract

Abnormal fMRI habituation in autism spectrum disorders (ASDs) has been proposed as a critical component in social impairment. This study investigated habituation to fearful faces and houses in ASD and whether fMRI measures of brain activity discriminate between ASD and typically developing (TD) controls. Two identical fMRI runs presenting masked fearful faces, houses, and scrambled images were collected. We found significantly slower fMRI responses to fearful faces but not houses in ASD. In addition, the pattern of slow to emerge amygdala activation to faces had robust discriminability [ASD vs. TD; area under the curve (AUC) = .852, p < .001]. In contrast, habituation to houses had no predictive value (AUC = .573, p = .365). Amygdala habituation to emotional faces may be useful for quantifying risk in ASD.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 September 2015.
All research outputs
#10,914,044
of 12,316,253 outputs
Outputs from Journal of Autism & Developmental Disorders
#2,830
of 3,051 outputs
Outputs of similar age
#201,870
of 245,766 outputs
Outputs of similar age from Journal of Autism & Developmental Disorders
#130
of 134 outputs
Altmetric has tracked 12,316,253 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,051 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.7. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 245,766 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 134 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
