(+) Supporting Research - Stirling et al (Stroop test) (CCD)

• All participants had to say the correct colour the words in the list were written in.

• Schizophrenic participants had a larger standard deviation, meaning their results were more spread out and further away from the mean.

(+) Supporting Research - Bentall: categories and examples (MRD)

• Participants came up with their own examples. Participants then asked to recall whether or not a word from one category was from their list or the researchers list.

• Found that Sz patients who had hallucinations performed worse, then Sz without hallucinations and non Sz patients did best.
