Q

What does it mean to say that there are biopsychosocial effects related to assessment

A

injury does not occur in a vacuum, occurs in a real world meaning there is an interaction between actual injury, psychological factors (personality, values, etc), environmental factors (ex. culture)

compared to studying lab animals, that seems like it is in a more vacuum environment

Q

What are some of the goals of neuropsychological testing

A
  1. aims to determine level of cerebral functioning and dysfunctioning
  2. facilitate patient care and rehabilitation
  3. identify mild disturbances when other studies are uncertain
  4. identify unusual brain organization (ex. left handers, kids with early brain injury)
  5. confirm an abnormal EEG in epilepsy
  6. document recovery (compensation)
  7. promote realistic outcomes

Q

How can we identify faking memory loss

A

ex. get injury from work, so might want to make it so you do not have to go back to work

Hiscock test = 5 digit numbers, ask which one they have seen before
amnesics do just fine, people faking do badly
OR
ask people to guess what time it is, usually people capable of guessing within 10 minutes
