The main aim of this thesis was to find how fast memory decreases for tasks that people need
to do. In order to do that an online survey was conducted where participants were asked to write
five tasks they needed to do in the next seven days, then they were asked to wait for a while
and finally rewrite those tasks. The results showed that there are two significant decreases in
memory performance. First there is a significant decrease between a 10-minute delay period
and one hour and the other is between a one hour and 24-hour delay period. The second aim of
this thesis was to test some of the results found in previous works. Results show that there
seems to exist a primacy effect, however no evidences of a recency effect was found, no
evidence that gender affects memory prediction and performance plus, results were negative
for an overestimate of participants’ prediction regarding their memory performance. Results
contradict previous works since the methodology used in studies on the field of memory are
usually done in a laboratory, they usually require participants to learn new things to later be
remembered and finally, the tasks and things participants are requested to do are usually abstract
or irrelevant for their lives. This study has none of those features thus the results are not as one
would predict
