Block and Block Longitudinal Study
The Block and Block Longitudinal Study examined personality and cognitive development from childhood to early adulthood for a sample of 128 children. In particular, the study sought to investigate the concepts of ego-control and ego-resiliency. Ego control refers to the delaying of behavioral impulses; undercontrollers tend to act more spontaneously, while overcontrollers are more constrained. Ego resiliency refers to a person’s ability to moderate their level of ego control to fit a particular situation. Children were assessed at ages 3, 4, 5, 7, 11, 14, 18, 23, and 32; data collection began in 1969 and concluded in 1999. A wide variety of data were collected, including school and demographic information; evaluations by teachers, parents, and observers; standardized psychological tests; and self-report questionnaires.
