Teuber and Weinstein, 1954

Cohort

35 men with brain injury selected from 185 with missile wounds of head, 12 controls with peripheral nerve injury wounds of head controls chosen from 101 with missile wounds of peripheral nerves

Penetrating missile injuries of head or peripheral nerves

Form Board Test

Brain-injured subjects took more time, made more errors, recalled fewer forms than controls

 

Subjects, controls sustained injuries 5–8 years before testing

 

Subjects grouped on basis of location of lesions

Weinstein and Teuber, 1957b

Cohort

62 men with loss of cerebral tissue due to penetrating head trauma, 50 controls with peripheral nerve injury

Penetrating head trauma or peripheral nerve trauma

AGCT administered 13–15 years before injury (on induction into Army)

Controls had mean increase of 13.0 AGCT points from preinjury to postinjury testing

Eliminated men with aphasic difficulties that prevented them from reading practice-test questions

Preinjury AGCT score available for 53 subjects

Preinjury educational level determined by interview and from case records

 

Brain-injured group, excluding aphasics, had average increase of 5.2 points; total brain-injured group had increase of 1.6 points

AGCT administered again 10–12 years after injury

Education before injury did not influence extent to which performance on intelligence test was affected after injury
