Aim:
Investigate how culture and schooling influence memory strategies in children from different backgrounds
Procedure:
Compared Liberian children (both schooled and unschooled) to US children
Ppts shown 20 culturally relevant objects one at a time and asked to recall them in any order
Researchers observed cognitive activities beforehand and collaborated with local university-educated experiments to ensure cultural relevance
In a later trial the objects were presented in the context of a story
Findings:
School Liberian children and US children quickly learned the word list and used categorical clustering to aid memory
Non-school Liberian children showed no significant improvement in recall
Conclusion:
Memory strategies are influenced by cultural and educational experiences
Ability to remember is universal
Specific strategies for memory are shaped by one's environment and education
Evaluation:
(+) High ecological validity - uses culturally adapted materials and collaboration with local experimenters
(+) High generalisability - sample had ppts from two different cultural backgrounds allowing for some cross-cultural comparision
(-) low internal validity - quasi experiment means that a cause and effect relationship can't be established
