ABSTRACT

Objective:

The human parental brain is a discrete set of interacting brain circuits that related with child-care feelings and behaviors.The research on it can help us to understand the essence of human parent-child re-lationship formation.In order to provide materials for the research of human parental brain and related fields,the study is ready to establish a set of standardized Chinese Infant Affective Face Picture System.

Methods:

By using convenience sampling,a total of 360 infant facial expression pictures of 211 Chinese infants aged from 3 to 6 months were collected.After standard processing on the photos,196 unmarried and nulliparous college students re-cruited from two universities in Chongqing and Guiyang were asked to assess them.One hundred subjects assessed the emotion categories and intensity of the pictures,and other 96 subjects assessed the emotion valence,arousal and dominance of the selected pictures.

Results:

The Chinese Infant Affective Face Picture System,containing 117 hap-py,92 neutral,108 sad expression pictures,was established.At the same time,the corresponding average identifica-tion rate were 89%,77%,92%,the intensity were 5.83,5.15,and 6.19,the valence were 5.92,4.55 and 2.70,the arousal were 5.11,4.18,3.77,and the dominance were 5.02,4.93,and 4.91.The system could effectively stimu-late participants'emotional reactions.There were statistically significant differences in scores of the established va-lence,arousal and dominance index between the 3 kinds of expression pictures (Ps <0.01).

Conclusion:

The Chi-nese Infant Affective Face Picture System has higher reliability and validity.The system could be used as emotional stimulus materials for the study of parental brain or emotion researches.
