Final answer:
Tanya's emotional adaptation to winning the lottery and finding the birth of her daughter more exciting afterward is an example of the Adaptation Level Theory.
Step-by-step explanation:
The example of Tanya, who experienced two significant life events—winning the lottery and giving birth to her daughter Sophia—and felt that the latter was the most exciting is an illustration of Adaptation Level Theory. This theory, proposed by psychologist Harry Helson, suggests that people adapt to changes in their life, such as a sudden increase in wealth, and thus their excitement diminishes over time. Once an individual adapts to a particular level of happiness, it takes a new and more significant change, such as having a child, to alter this level again. Therefore, Tanya’s experience aligns with (A) The adaptation level theory.
The situation described in the question illustrates the Adaptation Level Theory. According to this theory, individuals tend to adapt to new circumstances or experiences, causing their initial excitement or happiness to fade over time. Tanya initially found winning the lottery to be the most exciting thing until she gave birth to her daughter, which became a new and more exciting experience for her.
