Title: Double-Blind Procedure BUT Participants know what group they are in
Post by: dzzhao on March 01, 2012, 05:17:58 pm

Would you say the experiment used a double-blind procedure if the researcher got an assistant to execute the experiment, however the participants knew which IV/DV group they were in.

For example - conducting an experiment on sleep deprivation, the participants were randomly allocated to groups who slept 8 hours, 4hours and no sleep, but the researcher got an assistant to conduct the test afterwards on recall of words.

Double-blind? yes or no? to an extent? I always thought the main reason for double-blind was so experimenter effect was eliminated, so I said yes, but still want confirmation, thanks!

That's a tough one. I wouldn't call it double-blind as only the assistant is 'blinded'. I'd say single blind :)
