  to investigate the effects of amphetamine on cerebral blood flow during cognitive tasks
• what does WCST stand for

  wisconsin card sort task
• what type of scanner was used in daniel and weinberger?


  spect
• did the amphetamine increase pre-frontal cortex activity in the cognitive task?

  yes, but it reduced blood flow
• daniel and weinberger eval


  culture bias, ethical concerns as spect is dangerous, stabilising drugs may have been an extraneous variable
