maternal experience, emotion perception, and anxiety_data_mm.xlsx

Data for article "Maternal Nurturing experiences affects the perception and recognition of adult -but not infant- facial expressions" in PLOS ONE (under review). <br> <br> The present study investigated whether and how maternal nurturing experience influences the perception and recognition of both infant and adult facial expressions. We also consider the relationship with trait anxiety as an individual personal factor.<br><br> The sensitivity to emotion signals were assessed by comparing the performance of primiparous mothers (<i>n</i> = 25) whose infant were 7- to 10-months old and non-mothers (<i>n</i> = 28) on an emotional face perception task. We used unknown infant and adult stimuli (i.e., neutral, happy, sad) which were changed gradually differing emotional intensity in 10 stages from neutral to 100% intense emotional expressions. Participants asked to detect (1) whether they perceive the emotional signal or not, and (2) The emotion category they perceived from stimuli (happy or sad). we defined sensitivity and accuracy of emotional signals as follows. Sensitivity; as an index of perception of emotional signals, which means the thresholds of detecting facial emotional signals from. A<i>ccuracy</i>; as an index of recognition of emotional signals, which means the accuracy of identifying a category of emotional signals. Trait anxiety was measured with the Japanese version of the State-Trait Anxiety Inventory (STAI). <br> The data includes following: (1) Sheet1 includes general information of participant (age, ID, stimuli gender), the threshold scores of emotion perception task, and STAI questionnaire scores. (2) Sheet2 is a data set for MPT modeling analysis, which was used to examine whether accuracy for recognizing emotion signal was different between group (mothers v.s non-mothers).
