The Research by Judith Rodin and Ellen Langer Involving Elderly

The research by Judith Rodin and Ellen Langer involving elderly nursing home residents demonstrated that:

A) elderly nursing home residents are more likely to experience stress-related illnesses than elderly people living in their own home.
B) elderly nursing home residents who have a sense of control over their environment are healthier than elderly nursing home residents without a sense of personal control over their environment.
C) a sense of personal control reduces stress in younger people but adds to the level of stress experienced by elderly nursing home residents.
D) having many choices about their daily activities tended to make the elderly nursing home residents anxious.
