Development and Feasibility of MindChip™: A Social Emotional Telehealth Intervention for Autistic Adults
2021
The study aims to develop and pilot a telehealth social emotional program, MindChip™ delivered with a computer based interventions (CBI) (Mind Reading
©
) for autistic adults. MindChip™ combined four theoretical perspectives and community feedback underpinning the essential mechanisms for targeting the social emotional understanding of autistic adults. A randomised pragmatic pilot trial (N = 25) was conducted to explore the feasibility of MindChip™ (n = 11) and to understand the preliminary efficacy of combining it with CBI compared to CBI only (n = 14). The use of MindChip™ and CBI combined demonstrated partial feasibility, with preliminary efficacy findings revealing increased emotion recognition generalisation outcomes compared to CBI only. Further research is required to improve the engagement and personalisation of the intervention for autistic adults.

Inhibitory attentional control in anxiety: Manipulating cognitive load in an antisaccade task
2018
Theorists have proposed that heightened anxiety vulnerability is characterised by reduced attentional control performance and have made the prediction in turn that elevating cognitive load will adversely impact attentional control performance for high anxious individuals to a greater degree than low anxious individuals. Critically however, existing attempts to test this prediction have been limited in their methodology and have presented inconsistent findings. Using a methodology capable of overcoming the limitations of previous research, the present study sought to investigate the effect of manipulating cognitive load on inhibitory attentional control performance of high anxious and low anxious individuals. High and low trait anxious participants completed an antisaccade task, requiring the execution of prosaccades towards, or antisaccades away from, emotionally toned stimuli while eye movements were recorded. Participants completed the antisaccade task under conditions that concurrently imposed a lesser cognitive load, or greater cognitive load. Analysis of participants' saccade latencies revealed high trait anxious participants demonstrated generally poorer inhibitory attentional control performance as compared to low trait anxious participants. Furthermore, conditions imposing greater cognitive load, as compared to lesser cognitive load, resulted in enhanced inhibitory attentional control performance across participants generally. Crucially however, analyses did not reveal an effect of cognitive load condition on anxiety-linked differences in inhibitory attentional control performance, indicating that elevating cognitive load did not adversely impact attentional control performance for high anxious individuals to a greater degree than low anxious individuals. Hence, the present findings are inconsistent with predictions made by some theorists and are in contrast to the findings of earlier investigations. These findings further highlight the need for research into the relationship between anxiety, attentional control, and cognitive load.

This study investigated the feasibility and cultural validity of KONTAKT©, a manualised social skills group training, in improving the social functioning of adolescents with autism spectrum disorder (ASD). KONTAKT© was delivered to 17 adolescents (mage = 14.09, SDage = 1.43; 70% male) with ASD over sixteen 90 min sessions. A pre-test post-test design evaluated changes in personally meaningful social goals, symptom severity, quality of life, interpersonal efficacy, social anxiety, loneliness, and facial emotion recognition at pre, post and 3 months follow-up. Focus groups were conducted post intervention. Findings indicate that KONTAKT© may support Australian adolescents with ASD in achieving their personally meaningful social goals. This study resulted in finalisation of KONTAKT© in preparation for evaluation of its efficacy in a randomised controlled trial (Australian New Zealand Clinical Registry (ANZCTR): ACTRN12617001117303, ClinicalTrials.gov: NCT03294668).

Biased Saccadic Responses to Emotional Stimuli in Anxiety: An Antisaccade Study
2014
Research suggests that anxiety is maintained by an attentional bias to threat, and a growing base of evidence suggests that anxiety may additionally be associated with the deficient attentional processing of positive stimuli. The present study sought to examine whether such anxiety-linked attentional biases were associated with either stimulus driven or attentional control mechanisms of attentional selectivity. High and low trait anxious participants completed an emotional variant of an antisaccade task, in which they were required to prosaccade towards, or antisaccade away from a positive, neutral or threat stimulus, while eye movements were recorded. While low anxious participants were found to be slower to saccade in response to positive stimuli, irrespectively of whether a pro- or antisaccade was required, such a bias was absent in high anxious individuals. Analysis of erroneous antisaccades further revealed at trend level, that anxiety was associated with reduced peak velocity in response to threat. The findings suggest that anxiety is associated with the aberrant processing of positive stimuli, and greater compensatory efforts in the inhibition of threat. The findings further highlight the relevance of considering saccade peak velocity in the assessment of anxiety-linked attentional processing.

KONTAKT© for Australian adolescents on the autism spectrum: protocol of a randomized control trial
2019
Background
Individuals diagnosed with autism spectrum disorder (ASD) experience impairing challenges in social communication and interaction across multiple contexts. While social skills group training (SSGT) has shown moderate effects on various sociability outcomes in ASD, there is a need for (1) replication of effects in additional clinical and cultural contexts, (2) designs that employ active control groups, (3) calculation of health economic benefits, (4) identification of the optimal training duration, and (5) measurement of individual goals and quality of life outcomes.
Method/design
With the aim of investigating the efficacy and cost-effectiveness of a SSGT, KONTAKT©, a two-armed randomized control trial with adolescents aged 12–17 years (
N
= 90) with ASD and an intelligence quotient (IQ) of over 70 will be undertaken. Following stratification for centre and gender, participants will be randomly assigned to either KONTAKT© or to an active control group, a group-based cooking programme. Participants will attend both programmes in groups of 6–8 adolescents, over 16 one-and-a-half-hour sessions. The primary outcome examined is adolescent self-rated achievement of personally meaningful social goals as assessed via the Goal Attainment Scaling during an interview with a blinded clinician. Secondary outcomes include adolescent self-reported interpersonal efficacy, quality of life, social anxiety, loneliness, face emotion recognition performance and associated gaze behaviour, and parent proxy reports of autistic traits, quality of life, social functioning, and emotion recognition and expression. Cost-effectiveness will be investigated in relation to direct and indirect societal and healthcare costs.
Discussion
The primary outcomes of this study will be evidenced in the anticipated achievement of adolescents’ personally meaningful social goals following participation in KONTAKT© as compared to the active control group. This design will enable rigorous evaluation of the efficacy of KONTAKT©, exercising control over the possibly confounding effect of exposure to a social context of peers with a diagnosis of ASD.

Designing a Serious Game for Youth with ASD: Perspectives from End-Users and Professionals
2019
Recent years have seen an emergence of social emotional computer games for individuals with Autism Spectrum Disorder (ASD). These games are heterogeneous in design with few underpinned by theoretically informed approaches to computer-based interventions. Guided by the serious game framework outlined by Whyte et al. (Journal of Autism and Developmental Disorders 45(12):1–12,
2014
), this study aimed to identify the key motivating and learning features for serious games targeting emotion recognition skills from the perspectives of 11 youth with ASD and 11 experienced professionals. Results demonstrated that youth emphasised the motivating aspects of game design, while the professionals stressed embedding elements facilitating the generalisation of acquired skills. Both complementary and differing views provide suggestions for the application of serious game principles in a potential serious game.

Atypical Visual Processing but Comparable Levels of Emotion Recognition in Adults with Autism During the Processing of Social Scenes
2019
Understanding the underlying visual scanning patterns of individuals with autism spectrum disorder (ASD) during the processing of complex emotional scenes remains limited. This study compared the complex emotion recognition performance of adults with ASD (n = 23) and matched neurotypical participants (n = 25) using the Reading the Mind in Films Task. Behaviourally, both groups exhibited similar emotion recognition accuracy. Visual fixation time towards key social regions of each stimuli was examined via eye tracking. Individuals with ASD demonstrated significantly longer fixation time towards the non-social areas. No group differences were evident for the facial and body regions of all characters in the social scenes. The findings provide evidence of the heterogeneity associated with complex emotion processing in individuals with ASD.

Purpose of Review
A broad base of research has sought to identify the biases in selective attention which characterize social anxiety, with the emergent use of eye tracking-based methods. This article seeks to provide a review of eye tracking studies examining selective attention biases in social anxiety.
Recent Findings
Across a number of contexts, social anxiety may be associated with a mix of both vigilant and avoidant patterns of attention with respect to the processing of emotional social stimuli. Socially anxious individuals may additionally avoid maintaining eye contact and may exhibit a generalized vigilance via hyperscanning of their environment.
Summary
The findings highlight the utility of eye tracking methods for increasing understanding of the gaze-based biases which characterize social anxiety disorder, with promising avenues for future research.

Wearable technology (WT) to measure and support social and non-social functioning in Autism Spectrum Disorder (ASD) has been a growing interest of researchers over the past decade. There is however limited understanding of the WTs currently available for autistic individuals, and how they measure functioning in this population.This scoping review explored the use of WTs for measuring and supporting abilities, disabilities and functional skills in autistic youth.Four electronic databases were searched to identify literature investigating the use of WT in autistic youth, resulting in a total of 33 studies being reviewed. Descriptive and content analysis was conducted, with studies subsequently mapped to the ASD International Classification of Functioning, Disability and Health Core-sets and the ICF Child and Youth Version (ICF-CY).Studies were predominately pilot studies for novel devices. WTs measured a range of physiological and behavioural functions to objectively measure stereotypical motor movements, social function, communication, and emotion regulation in autistic youth in the context of a range of environments and activities.While this review raises promising prospects for the use of WTs for autistic youth, the current evidence is limited and requires further investigation.

Effects of intensity on emotion regulation strategy preferences are emotion-specific
2024
Adaptive emotion regulation is characterized by the ability to flexibly select and switch between different strategies, depending on individual and contextual factors. Previous studies have shown that people prefer disengagement strategies to regulate more intense emotions, while they prefer engagement strategies to regulate less intense emotions. In this study, we investigated whether – in addition to the intensity of emotions – the discrete emotion type (disgust versus fear) also affects emotion regulation strategy preferences. A total of 401 students from three different universities completed an emotion regulation choice task in which they could choose between distraction and reappraisal to regulate their emotions in response to viewing high versus low intensity disgust- and fear-evoking pictures. We found that strategy choices did indeed depend on the nature of specific emotions, with distraction being preferred for regulating disgust, and reappraisal being preferred for regulating fear. Crucially, the nature of the emotion also qualified the previously reported effect of emotion intensity on strategy choice: Only for disgust- but not for fear-evoking pictures did participants show an increased preference for distraction over reappraisal with increased emotion intensity. Our results thus show that the effects of emotional intensity on emotion regulation strategy choice are emotion-specific and indicate that factors affecting emotion regulation strategy choice interact with each other.
