What statistical test should I run for the following study
Study 1:
STUDY 3:
Reasearch Question: Adults compared to children might adopt more sophisticated eye-following behaviours (i.e., better at looking the eye, and for longer times) as they are more experienced and advanced in communications and other forms of social interactions.
Aim: To explore whether the following gaze behaviours might differ from people from different age groups.
Main effect of image type: A larger proportion of fixations on the face for the Human than the
monster images.
Main effect of age: children might spend a larger proportion of fixations on the faces than adults
because of curiosity,
Interaction between image types: difference in the mean proportion of fixations on the face would
be larger for university students than that of the primary school children due to more sophisticated
eye-following behaviours.
Design:
Between-subjects design
2 (image types: Human vs. Monster) × 2 (age group: Primary School vs. University
Students).
Demographic:
Participants were recruited from two age groups: primary school students and university
students
80 participants total
20 Participants within each image and age group
2 IVs:
Human
Monster
6 conditions: (run on STATA)
Gender = Participants' gender
Age = Participants' age
Image = type of image
Ssgroup = the age group
Condition = unique combination of the image type and the age group
Faceperc = the mean proportion of fixations on the face across 36 images
