Abstract:The current study examines whether the semantic memory is usable in a real world setting. The study of Huth et al. (2016a) has developed a map on which the semantic memory is projected. By scanning brain activity with an fMRI scanner from participants while the participants listen to natural stories, certain voxels in the brain get activated by hearing certain words. This map is divided into different clusters with corresponding words. The current study examines six clusters on their usability with a card sorting task and a questionnaire. A list of 50 words from the six clusters is made to test their usability outside a laboratory, and is analysed by comparing the results with the study of Huth et al. (2016a). The results of the card sorting task is a heatmap, on which actual numbers like two and three have a clear result. By comparing this result with the study of Huth et al. (2016a) and other literature, it becomes clear that actual numbers from the semantic memory are usable in a real world setting. The questionnaire gives other results, such as that four of the six tested clusters are adequately labelled to be recognized by participants, thus improving their usability. The discrepancy between the card sorting task and the questionnaire can be clarified through a familiarity bias of the participants. Participants have worked in the card sorting task with the same 50 selected words as the words used in the questionnaire.
