t has been hypothesized that, when practicing several skills at once, learning can be enhanced through random practice designs which increase the meaningfulness or distinctiveness of the various movements, presumably making each skill more durable in long-term memory and resulting in easier recall at a later time (i.e., making the skills less susceptible to forgetting). This idea is expressed by the ________ hypothesis.

As the exercise explains, the idea of elaboration hypothesis explains how, when practicing several skills at once, learning can be enhanced through random practice designs which increase the meaningfulness or distinctiveness of the various movements, presumably making each skill more durable in long-term memory and resulting in easier recall at a later time (i.e., making the skills less susceptible to forgetting). So, in other words, this hypothesis states that during a practice people may discover or elaborate (hence the name) distinctions of the skills they are training, which is highly beneficial to maintain the knowledge.
