Design of the Month


The following was reported in the New Scientist on 4 July 2009.

Picard and Rana el Kaliouby of MIT have built an "Interactive Social-Emotional Toolkit" (iSET), designed to help children with disorders linked to sensory processing, such as autism, to understand emotions in other people. ...

The team will begin randomised trials of the technology this month. For 15 weeks, one group of five autistic children will use the iSET, while two control groups will use either an interactive DVD that teaches emotional awareness or have only standard classroom training. Before and afterwards, the researchers will test how well the children identify emotional expressions unaided by the iSET to see if the technology helps them learn to identify emotions for themselves.

  1. What are the treatments and how many of them are there?
  2. What are the observational units and how many of them are there?
  3. What are the experimental units and how many of them are there?
  4. What response wil be measured on each observational unit?
  5. What is the replication?
  6. What does `randomised' mean here?
