Classic Studies Issues In Design And Implamentation Of Research

Question 1

Sherif et al

Answer 1

• the procedure was not generalisable with 22, 11yo boys from white Protestant families
• the study was hard to replicate as it was a field experiment
• however high ecological validity as natural environment
• not ethical procedure
  -high task validity as tasks from a normal summer camp

Question 2

Baddley

Answer 2

• low task validity with lists of 10 words
• low ecological validity as lab environment
• not generalisable as sample of 75 young service men
• low internal validity as the influence of the STM was not ruled out at pp could rehearse between trials
• well controlled procedure so high reliability as can be replicated to test for test-retest reliability

Question 3

Raine et al

Answer 3

• low generalisability as sample of NGRI prisoners
• high reliability due to consistence in neuro-imageing results
• internal validity as pet scan can be looked at by multiple researchers
• low validity as oversimplification of criminal activity to brain functioning

Question 4

Watson and Rayner

Answer 4

• not generalisable as only one baby boy
• not reliable as only one case so no other results to compare to
• well controlled procedure e.g show object before conditioning to gather baseline reaction
• lab experiment so low ecological validity

Question 5

Rosenhan

Answer 5

• not generalisable as study of only 8 peusopatients across clinics across North America
• high task and ecological validity as pp were not aware of study so displayed mundane realism
• reliable as standardised procedure e.g empty hollow thud as symptoms
