Final answer:
A psychologist with a focus on upbringing over current life events is likely to be a psychoanalyst or one of the neo-Freudians, who emphasize early childhood experiences and their lasting impact on an individual's development.
Step-by-step explanation:
The type of psychologist most likely to emphasize the importance of upbringing over current events in a person's life could be a psychoanalyst, a psychologist following the theories of Freud or his successors, which include the neo-Freudians. Freudian psychology stresses the significance of early childhood experiences and how these shape an individual's personality and behavior.
The neo-Freudians agreed with the importance of childhood experiences but shifted focus to include social and cultural factors. This view is reflected in various psychological studies and theories, such as the work of Diana Baumrind on parenting styles and their effects on children's socioemotional growth, as well as the research by Annette Lareau on how socioeconomic status influences parenting strategies and child development.
Psychologists who consider background and upbringing as central to understanding a person's issues often utilize a therapeutic approach that delves into childhood experiences and parental influences.
