Gaze Modification Strategies for Toddlers With Autism Spectrum Disorder (ASD)

March 3, 2020 updated by: Frederick Shic, Yale University
This project seeks to understand how the gaze behavior of infants and children with or at high risk for autism spectrum disorder (ASD) may be manipulated in the contexts of dynamic social and non-social scenes. The study explores not only the methods which may be most effective in aligning and teaching normative patterns of scene exploration, but also seeks to establish what behavioral characteristics may be most predictive of atypical scanning and atypical learning.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study initiates a highly novel line of research which uses adaptive, gaze-contingent, eye-tracking technology to help infants and children with or at high risk for ASD learn to direct their attention to people and their actions in a more typical fashion. This study will begin with a Normative Collection phase, and will conclude with a Gaze-Shaping phase. In the Normative Collection phase, the investigators will examine the gaze behavior of a group of typically developing infants and children with typical development (TD), in order to establish a normative gaze pattern. In the Gaze-Shaping phase, within the same videos shown in the Normative Collection phase, the investigators will highlight selectively targeted people, objects, and activities, in an attempt to shape participants' viewing patterns to match the normative gaze pattern.

Manual coding of live-action interaction probes will provide an additional evaluative measure, allowing the investigators to track real-world (live-action) correlates alongside video-eye-tracking behaviors. In addition, live-action probes may allow the investigators to check for generalization to live interaction with another person (as opposed to gaze behavior when watching videos). In live-action probes, one or two clinical research staff member(s) will interact with each participant (or with each other in front of the participant), in a manner analogous to the actions performed in the training videos.

Please note: The original estimated enrollment as specified to and funded by NIH was 98 participants, but was incorrectly listed on ClinicalTrials.gov as 220 participants reflecting maximal recruitment in this and other ongoing studies.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 5 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Between the ages of 18 and 60 months
  • Fulfill criteria for autistic disorder or PDD-NOS (Pervasive Developmental Disorder- Not Otherwise Specified) on the Autism Diagnostic Observation Schedule - Module 1
  • A diagnosis of autism or PDD-NOS by experienced clinicians

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Gaze Contingent
Participants will view social videos using Gaze-contingent eye-tracking technology . If the participants looking patterns deviate from a normative pattern, they will be redirected to the normative point of regard using gaze-contingent cues.
Other: Gaze-contingent eye-tracking technology
When participants look away from a prototypical or expected norm, their gaze patterns are redirected to those prototypical locations.
No Intervention: Control Condition
Participants will view unaltered social videos which do not change based on where the participant is looking.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Gaze behavior during eye tracking tasks measured by standard eye-tracking analysis protocols
Time Frame: 1-7 days
Outcome measures for eye-tracking will include the Percentage of Time Spent Looking at Face, Body, and Background regions for stimuli involving people, and Percentage of Time Spent Looking at Activity, People, and Background regions. Percentage of time spent looking at the video (i.e. overall attention less motion, blinks, and inattention) will be calculated. Additional variables specific to the training sessions' adaptive cue condition will include the number of times the stimuli is adapted to redirect attention to locations consistent with the typical viewing pattern) and the amount of time spent in redirection. These will all be assessed by standard eye-tracking analysis protocols.
1-7 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Behavior during real-world interactions measured by coding of video recordings
Time Frame: 1-7 days
Outcome measures include attention to social interactions and responses bids for engagement in social attention during a live experimental session, as measured by coding of video recordings.
1-7 days
