ecological account

• boler in 1997 found that contextual information is important in cueing memories findings regarding "reminding" show that cues are important to memory
• so infants need to be shown the mobile to recover knowledge as they have fewer memories so they have fewer cues so their retention is shorter
• so forgetting decreases with age because we have more experiences
• around 9 month infants can crawl this can expand their experience to new objects
• herbet gross and Hayne in 2007 compared the performance of a group who could crawl compared to one who could not on a deferred imitation task
• the crawling babies showed learning when the animal changed whereas the babies who could not crawl only showed memory when trained or test on the same animal
