Robert Bjork

Robert Bjork is a cognitive psychologist known for his research on human learning and memory. He emphasizes that effective learning involves meaningful, effortful engagement with material rather than just repetition. One of his key ideas is that challenging ourselves with slightly difficult tasks—desirable difficulties—can improve long-term understanding and retention. Bjork also highlights the importance of varied practice and spacing out study sessions over time, which helps solidify knowledge. His work has influenced educational methods, encouraging strategies that promote durable learning instead of quick, superficial memorization.
