Graffman Vietnam War Study Questions

What are the independent and dependent variables in the Grafman et al study?

• IV: Veterans with brain damages, DV: aggressive behavior

• IV: MRI technology, DV: aggressive behavior

• IV: Family observations, DV: aggressive behavior

• Verbal confrontations, DV: aggressive behavior

What is the aim of the study?

• To evaluate the use of MRI technology in the study

• To test the relationship between prefrontal cortex lesions and aggressive behavior

• To compare the behaviors of three groups in the study

• To identify the limitations of the study design

How many overall participants in this study?

• 179 Vietnam war veterans

• 279 Vietnam war veterans

• 279 Vietnam war veterans

• 479 Vietnam war veterans

What is a longitudinal study ?

• A longitudinal study involves studying a large sample size.

• A longitudinal study involves randomly allocating participants to different.

• A longitudinal study involves manipulating the independent variable.

• A longitudinal study involves repeated observations over a long period of time.

What is the implication of the results of the study?

• Verbal confrontations are more common than physical assaults in patients with frontal ventromedial lesions

• MRI technology is a reliable tool for studying brain damage

• The total size of the lesion is associated with aggressive and violent behaviors

• Damage to PFC is more likely to lead to aggressive behaviors than no damage or damage to other areas of the brain

This brain imaging technology measures the structure of human brain.

• fMRI

• EEG

• MRI

• None of the above

What is the localised brain area and behaviour linked with Grafman et al?

• PFC and criminology

• Frontal lobe and impulsive behaviour

• PFC and aggressive behaviour

• PFC and impulsive behaviour

VHIS stands for_________________

• Vietnam head and shoulder study

• Vietnam head injury study

• Vietnam healing and support study

• Vietnam health and survival study

What topic does this topic and approach PFC and aggressive behaviour fall as per your IB syllabus in P1?

• The brain and behaviour & Biological approach

• Hormones and behaviour & Biological approach

• The brain and behaviour & Cognitive approach

• Hormones and behaviour & Abnormal psychology

The prefrontal cortex also allows us to think about the long-term consequences of our actions and to run things through in our minds, so this is another way that it might help to control our impulsive reactions. True or false

• False

• True

• Sometimes

• I do not agree
