Across different blocks, volunteers responded to house but not face pictures, face but not house pictures, or passively viewed pictures without responding.
Next, the MCDASf items were read out by the researcher and the children were asked to answer each question using the cartoon faces picture cards as scoring options.
In study 1, Kendall W test showed a high degree of concordance in ranking the cartoon faces picture cards on each of the 2 occasions (time 1, W = 0.955 and time 2, W = 0.954).
In both sessions, face and non-face pictures were shown to participants.
However, employing a variable mapping of face pictures one recent report found preferential detection of own-race faces vs. other-race faces (Lipp et al., 2009).
Face pictures were 15 full-color 258 × 350 pixel photographs of men with neutral expressions, collected from the Karolinska Directed Emotional Faces database (Lundqvist, Flykt, & Öhman 1998).
However the performance of already exist system with the physical world face pictures, images are somewhat not excellent, particularly in comparison with the result of task related to face recognition.
There are nevertheless sets of face pictures normalized for variables not related to emotions but related to identity.
For face pictures, the oval crop was made inside the contour line of the face and all extra-facial information (hair around the face) was numerically erased.
Participants were informed that they would be presented with a series of face pictures in order to evaluate the emotional valence of each face stimulus shown.
For the familiar faces, pictures of each participant's close relatives (e.g., spouse, children) were taken with a digital camera.
