At the start of his 90-minute lecture on child development, Professor Mental shows his class a 10 minute home video of his own young children playing with their pet dog. When students later take an exam on this lecture, Professor Mental finds that the students did remember the details of the critical child development theories that were the focus of the above lecture. This effect has come to be known as: a)spacing effect b) the seductive detail effect c) the generation effect d) verbal overshadowing
