Gurney's Law is a principle in psychology that suggests people tend to remember the first and last items in a list better than those in the middle. This phenomenon is known as the serial position effect, which highlights how our memory is influenced by the order of information presented. The law was named after Robert Gurney, who studied this effect in the context of learning and memory. It has implications for various fields, including education and marketing, as it suggests that the placement of information can significantly impact retention and recall.
