Trial Outcomes & Findings for Training Attention and Eye Movement in ASD (NCT NCT02403817)

NCT ID: NCT02403817

Last Updated: 2019-12-04

Results Overview

This behavioral task assesses the participant's baseline ability to rapidly and accurately shift visual attention to different spatial locations. This task also reveals whether a participant becomes overly-focused ('stuck') at specific locations.

Eye Movement Game Control
Cognitive Training Eye Motor Training Cognitive Training: A collection of video games that rely on various aspects of visual behavior (i.e. sustained attention, vigilance, rapid discrimination, etc) for successful play. Eye Motor Training: Gameplay will be controlled by the player's eye movements (via an eye tracking device)
Hand Movement Game Control
Cognitive Training Hand Motor Training Cognitive Training: A collection of video games that rely on various aspects of visual behavior (i.e. sustained attention, vigilance, rapid discrimination, etc) for successful play. Hand Motor Training: Gameplay will be controlled by the player's hand movements (via a joystick).

PRIMARY outcome

Timeframe: Pre-intervention

Population: All participants who completed the 8 weeks of game-based training were analyzed.

This behavioral task assesses the participant's baseline ability to rapidly and accurately shift visual attention to different spatial locations. This task also reveals whether a participant becomes overly-focused ('stuck') at specific locations.

PRIMARY outcome

Timeframe: Pre-intervention

Population: Because of technical difficulties we have only partial data for this measure.

This task uses an eyetracker to measure the baseline speed and accuracy of a participant's saccadic eye movements in response to various stimuli. Measure is accuracy of first saccade in the anti-saccade task.
