This task was developed for research into the impact of surgical face masks on the categorisation of facial expressions of emotion. The task presents photographs of women and men posing seven facial expressions: neutral, happy, sad, angry, fearful, disgusted, and surprised. Each face is presented twice: once with a face mask superimposed over the nose and mouth, and once without a mask. Participants label the expression of each face in a 7-alternative forced-choice task.
Built with Task Builder 1
This task presents ten identities (five women, five men), each posing seven facial expressions: neutral, happy, sad, angry, fearful, disgusted, and surprised. Face stimuli were obtained from the Radboud Faces Database (Lagner et al., 2010). Each face is presented twice: once with a face mask superimposed over the nose and mouth, and once without a mask. Participants see 140 images in total (10 identities x 7 expressions x 2 mask conditions), which are presented in a random order. Images are presented at 4.8cm width (approximately 7cm height) on the participants’ screen. Trials begin with a fixation cross (1000ms) followed by a face image (500ms). The stimulus image is replaced by a mask image constructed of high-contrast greyscale ovals (500ms), followed by a response screen on which participants select one of seven response options (neutral, happy, sad, angry, fearful, disgusted, surprised). There is no time limit on participants' responses.
