This thesis utilised an experiment originally developed and applied by a research project investigating gender representations of readers and listeners in Norwegian, Finnish and French” (funded by NFR, FriPro project nr. 24088), referred to as the original experiment. The aim of this thesis was to further explore the role of task design and response set-up on response time (RT) in a modified version of that experiment. The response set-up was modified from a combination of bimanual- and unimanual responses to a full unimanual response design. 34 participants were recruited. They had to complete two different tasks over five experimental blocks: a button task (BT), where they had to press the corresponding response button to the stimuli presented (MM, FF, FM/MF), and a face pair decision task (FPDT), where they had to categorise face pairs according to gender (male faces, female faces, or both male- and female faces) before pressing the response button corresponding the presented face pair. Common for both tasks were the use of one overlapping category (FM/MF in the BT, a male- and a female face pair in the FPDT). The main focus of the thesis was the first BT and the first FPDT. In both task the overlapping category had significantly longer RT than the non-overlapping categories (p < .001). Current response set-up provided faster RT than the original response set-up in the BT (p = .010, contrast of 53 ms), RT between the original response set-up and the current response set-up in the FPDT was nonsignificant (p = .087), contrast indicates that the original response set-up provided faster RT by 93 ms. In conclusion, RT is dependent on both task design and response set-up.
