Blind Studies

• Sometimes ppts are not told the aim of the study.
• There are sometimes additional details that are kept from the ppt in the study:

  • Which condition they are taking part in.
  • Whether there is another condition at all.
• When this happens, it is called a single blind procedure.
• Sometimes neither the ppts or the researcher are aware of the aims of the investigation.
• When neither party are aware of the aims/ conditions, this is called a double blind procedure.
