How long did participants perform the Continuous Performance Task (CPT) in Raine et al.'s study?

  1. 20 minutes

  2. 30 minutes

  3. 32 minutes

  4. 40 minutes

The correct answer is: 32 minutes

In Raine et al.'s study, participants performed the Continuous Performance Task (CPT) for 32 minutes. This duration is crucial as it allows adequate time for participants to engage with the task sufficiently, ensuring that their responses could be reliably measured. The CPT is designed to assess attentional control and impulsivity, and the length of time spent on the task is significant for gathering data on cognitive functioning and behavioral responses. The specific choice of 32 minutes helps to standardize the task across all participants, enhancing the validity and reliability of the findings related to the cognitive processes being studied.
