简要总结

This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain mental abilities, such as speech, language and other efforts at communication in individuals with autism.

In this research, battery powered device is used to deliver very weak electrical current to the surface of the scalp while participants are involved in tasks aimed at training or measuring communicative efforts, speech, language or related cognitive functions. Our aim is to find out whether tDCS will improve these mental abilities.

详细描述

Participants in the study will be asked to do the following things:

  • Grant permission for the researchers to view medical/psychological and/or educational and/or speech records associated with the diagnosis of low-functioning autism.
  • Complete a questionnaire and provide a health history.
  • Complete evaluations by our study team to assess the diagnosis and gain a clearer understanding of the participant's current functioning.
  • Give permission to audio and video-tape test sessions for later scoring and observation.
  • Give permission to audio or video-tape in the classroom or home environment using non-intrusive audio-visual recording devices.
  • Complete several tasks and training interventions that involve such things as learning new words or pictures, saying words out loud, or naming objects.
  • Participate in an eye tracking study while completing a task on the computer which involves wearing a headband, attached by a velcro fastener, which contains a magnetic sensor. This equipment allows us to track the position of the head in order to record more accurate measurements. It is used with eye tracking equipment which measures the gaze on a set point on a computer screen. The equipment poses no risk and is non-invasive.
  • Participate in computerized tasks while monitoring brain responses that are a direct result of a thought or perception. In order to monitor these responses, electrodes would be placed over various points on your scalp. The electrodes will record the on-going activity of the brain; it does not produce or introduce any electrical activity. The equipment poses no risk and is non-invasive.
  • Wear electrodes that will be placed on the scalp with a large rubberized band. These electrodes will administer very weak electrical current (tDCS) from a battery powered device for 20 to 60 minutes.

The experimental sessions will last about 1 hour and participants may be asked to have more than one testing session in a day or to return for additional sessions.
