“…Although detailed socio-economic or ethnic data were not collected as part of this study, it should be noted that the recruitment area is a relatively wealthy, university town. Autonomic data collected from a subset of these infants (37) forms the basis for a previous paper looking at patterns of covariation between different autonomic measures (Wass et al, 2015). However, the present paper contains completely new analyses, addressing overlapping research questions, as described in detail in the Introduction.…”

“…Our previous analyses used zero-lagged correlations to examine phasic associations between levels on measure and on another measure at that same moment in time (Wass et al, 2015). It is possible, however, that changes in one measure may tend temporally to precede changes in anotherrelationships that would not be detected using zero-lagged analyses.…”

“…In a previous report we examined tonic and phasic patterns of covariation between heart rate, EDA, pupil size, head movement velocity and peripheral accelerometry in a cohort of 37 typical 12-month-old infants during the completion of a 20-minute testing battery (Wass, de Barbaro, & Clackson, 2015). We analysed co-variation of these autonomic indices in three ways: i) correlations in tonic (baseline) arousal levels, ii) co-variation in immediate phasic changes following the presentation of an attention-getting external stimulus and iii) patterns of co-variation in spontaneous changes during testing, relative to baseline.…”

Research from the animal literature suggest that dynamic, ongoing changes in arousal lead to dynamic changes in an individual's state of anticipatory readiness, influencing how individuals distribute their attention to the environment. However, multiple peripheral indices exist for studying arousal in humans, each showing change on different temporal scales, and links to attention remain relatively under-explored. Here, in 53 typical 12-month-olds, we recorded heart rate (HR), head movement patterns, electrodermal activity (EDA) and attention (indexed via look duration) during the presentation of 20 minutes of mixed animations and TV clips. Using crosscorrelations and auto-correlations, we found that HR and head movement show strong covariance on a sub-minute scale, with changes in head movement consistently preceding changes in HR.EDA showed significant covariance with both, but on much larger time-scales. HR and head movement showed consistent relationships with look duration, but the relationship is temporally specific: relations are observed between head movement, HR and look duration at 30 seconds' time-lag, but not at larger time intervals. No comparable relationships were found for EDA.Changes in head movement and HR occurred before changes in look duration, but not for EDA.Our results suggest that consistent patterns of covariation between heart rate, head movement and EDA can be identified, albeit on different time-scales, and that associations with look duration are present for head movement and heart rate, but not for EDA. Directions for future research are discussed.

“…In the same session, we also measured infants' physiological reactivity, indexed as heart rate acceleration while infants watched a video of another infant crying. In previous research we have shown that heart rate shows strong patterns of phasic covariation with other widely used measures of arousal such as electrodermal activity and movement patterns (Wass, Clackson & de Barbaro, 2015), validating its use as a single measure to index arousal.…”

Acute stress attenuates frontal lobe functioning and increases distractibility while enhancing subcortical processes in both human and nonhuman animals (Arnsten, 1998, Arnsten et al., 1998, Skosnik, 1999. To date however these relations have not been examined for their potential effects in developing populations. Here, we examined the relationship between stress reactivity (infants' heart rate response to watching videos of another child crying) and infant performance on measures of looking duration and visual recognition memory. Our findings indicate that infants with increased stress reactivity showed shorter look durations and more novelty preference. Thus, stress appears to lead to a faster, more stimulus-ready attentional profile in infants. Additional work is required to assess potential negative consequences of stimulus-responsivity, such as decreased focus or distractibility.

The neurobiological presentation of anxiety in autism spectrum disorder: A systematic review

Anxiety is common among people with autism and is associated with unique and additive challenges. Anxiety is thought to have neurobiological components, and measures of arousal in typical development have long been studied. Recently, neurobiological measures of anxiety in autism have begun to receive empirical evaluation, but results have not yet been examined together. This systematic review, therefore, summarizes the state of the research of the neurobiology of anxiety in autism. Studies published between 1999 and June 2017 were reviewed. Results across measures of arousal point to inconsistencies in results and a lack of synthesis in the literature. Considerations regarding these inconsistencies are discussed, recommendations for future studies are offered, and clinical implications for this work are presented. Autism Res 2019, 12: 346–369 © 2019 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary Anxiety is common among people with autism. Because anxiety has been linked with a variety of differences in physiological (bodily) and neurophysiological (brain) functioning in people without autism, research has begun to examine these processes in autism as well. This literature, however, has not yet been examined as a whole. Therefore, this paper begins to address that gap to provide the field with a better understanding of how anxiety affects people with autism and discusses implications for future research and clinical practice.
