Answer:
Bella's recall will be better than Anna's
Step-by-step explanation:
The levels of processing model is a model that focuses on how we process information and how this process affects our later recall of the information.
According to this model, the more we process information (in a more elaborate level), the longer the memory will last. Thus, a shallow level of analysis would make the memories dissapear more quickly.
In this example, Anna gets a word list and repeats it over and over (she is not engaging in an in-depth analysis). Her twin Bella gets the same word list and comes up with a story using each word (she processes the information in a more elaborate level). Thus, according to this theory we would expect that Bella's recall will be better than Anna's since she was engaged in a more elaborate processing of information.
