From the abstract: "Disparate lines of research suggest that women’s (a) emotion regulation and personality, (b) executive function and (c) sleep may be important predictors of mothers’ cry responding in part through their effects on social cognition. However, the extent to which each contributes to cry responding independently remains unknown. We examined this question in a convenience sample of 109 nulliparous undergraduate women. Women completed online surveys to assess personality and emotion dysregulation traits, then visited the lab for a testing session during which they reported on sleep the night before and reactions to videotapes of crying infants and completed computerized working memory and inhibitory control tasks under challenging noise conditions (exposure to traffic and cry sounds). Results indicate that women’s positive personality and higher working memory were associated with higher levels of infant-oriented cry processing (i.e., accurate distress detection, empathy and situational/emotional attributions about distress), which in turn was associated with higher intended responsiveness to infant crying. Emotion dysregulation and deficits in inhibitory control were associated with higher levels of self-oriented cry processing (i.e., anger, anxiety, negative and emotion minimizing attributions in response to infant distress), which in turn was associated with lower cry responsiveness. Short-term sleep deprivation was associated with lower intended responsiveness via the above path from poorer inhibitory control to heightened self-oriented cry processing. Findings suggest that sleep, emotional and cognitive factors are associated with cry processing and subsequent responsiveness independent of one another."
