Question 329

Study of Cognitive Functioning

In an investigation into cognitive executive functioning, researchers used a standardized digit-span task to compare two groups of participants.

  • Group A consisted of a volunteer sample of patients diagnosed with schizophrenia who actively attend a specialized outpatient art therapy program at an urban clinic.
  • Group B (the control group) consisted of a volunteer sample of local university maintenance staff who responded to an email flyer.

The researchers compared the digit-span scores of the two groups to analyze differences in working memory capacity.

Explain one reason why there might be a problem of bias and generalisation in this study. How could the researchers modify their study to deal with this problem?
