When trying to forget something disturbing, we suggest that you try jogging your memory in the more distant past. A study says it helps.
It is known that when you are daydreaming, it becomes difficult to remember what was going on before you stopped paying attention.
Psychologists have known for a while that context is important to remembering. If you leave the place where a memory was made - its context - it will be harder for you to recall the memory.
Previous studies had also found that thinking about something else - daydreaming or mind wandering - blocks access to memories of the recent past.
Psychological scientists Peter F. Delaney and Lili Sahakyan of the University of North Carolina at Greensboro and Colleen M. Kelley and Carissa A. Zimmerman of Florida State University wanted to know if the content of your daydreams affects your ability to access a recently-acquired memory.
For one experiment, each participant looked at a list of words as they appeared on a computer screen, one at a time.
Then they were told to think either about home - where they'd been that morning - or about their parents' house - where they hadn't been in several weeks. Next, the participant was shown a second list of words.
At the end of the test, they had to recall as many of the words from the two lists as possible.
