The Milgram experiment's ethical considerations and criticism centered on its psychological impact on participants. It raised concerns about the potential emotional stress inflicted on the individuals involved in the study.

The Whitehall Studies investigated social determinants of health, specifically the cardiovascular disease prevalence and mortality rates among British civil servants.The initial prospective cohort study, the Whitehall I Study, [1] examined over 17,500 male civil servants between the ages of 20 and 64, and was conducted over a period of ten years, beginning in 1967.
His research concerned developmental changes in adult intelligence, the impact of cognitive behavior in midlife and the integrity of brain structures in old age, and early detection of risk for dementia. [3] Schaie also studied developmental research methodology in addition to the applications of the age-cohort-period model to psychology.
Psychologist Jonathan Freedman's experiment recruited high school and university students to carry out a series of experiments that measured the effects of density on human behavior. He measured their stress, discomfort, aggression, competitiveness, and general unpleasantness. He declared to have found no appreciable negative effects in 1975. [15]
