Hur olika faktorer påverkar minnesprestation - en analys med användning av bootstrap

Sammanfattning: The current paper examines to what extent different factors influence our ability to remember. Data used in the analysis origins from a psychological memory experiment conducted at the University of Lund. During the study phase of the experiment, participants viewed different objects which could either appear as a word or a picture. The object type was randomly chosen which resulted in varying sequences of each object type. In the later test phase participants were asked about the objects and their properties. One of the factors analyzed is what impact the switching of object type has on the memory performance. In order to examine this, data was split up into categories depending on if a switch was present or not. Each participant’s mean was calculated for each category. Any potential differences between the categories were then compared by using bootstrap. The second factor examined concerns if the position (beginning, middle or end) of the object during the study phase influences the performance. The procedure used had much resemblance with the above mentioned calculations. Results from these two analyses suggest that the switching of object type has quite an impact on memory performance while the position during the study phase hardly affects the performance at all. MatLab, MS Excel and SPSS were utilized for the analyses.
