Abstract:The present study investigates whether human semantic systems are comparable to semantic systems generated through statistical measures. A study by Huth et. al (2016) mapped out the semantic system by scanning for oxygen level dependent responses within the brain of participants during the reading of stories. Individual words of the stories are then mapped onto a 3D-voxel-based model of the brain. 11 categories were created to encompass the semantic meaning of all words; generated through logical and statistical methods. The present study examines the validity of six of the 11 clusters through a card sorting task and questionnaire. A list of 50 words are equally chosen from the six clusters and written onto cards, and participants are asked to sort them into semantically related groups. The final result, a heat map, generated from the card sort task, can be used to determine clusters of items grouped by the participants. By comparing the results of the card sorting task to Huth et. al (2016), one can see that there are little differences that can be reasoned through individual variances and background. The study shows that at least four out of the six categories are adequately labeled, and that the remaining categories are reflective of the structure in a human mind.
