“…While the current study is worthy from the viewpoint of the general tendency in maternal behavior, future studies should address individual differences in maternal approach-avoidance behavior to infant vocalization. Recently, several studies have revealed that Oxytocin receptor gene polymorphism moderates the effects of childhood experiences on behavioral and physiological responses to infant crying (Esposito et al, 2017; Hiraoka and Nomura, 2019; Senese et al, 2019). Since this gene x environment approach is useful for revealing the mechanism shaping the parenting behavior, future research should examine the gene x environment effects on maternal postural movement.…”

Infant vocalization plays a pivotal role in communicating infant mood to parents and thereby motivating parenting responses. Although many psychological and neural responses to infant vocalization have been reported, few studies have examined maternal approach-avoidance behavior in response to infant vocalization. Thus, this research sought to determine how infant emotional vocalization affects maternal behavior. Twenty mothers participated in this behavioral study, all of whom had infants of 24 months old or less. In the experiment, they stood on a Balance Board that collected real-time data regarding center of pressure (COP), while listening to a series of infant vocalizations including cry, laugh, and babbling. They then listened to the same vocalizations for a second time and rated their felt emotions in response to each vocalization. The participants demonstrated significant postural movements of approaching in response to cry stimuli or to stimuli regarded as highly urgent. In contrast, they demonstrated postural movement of avoidance in response to laugh vocalization. These findings suggest that parenting behavior in response to infant emotional vocalization is regulated not by the pleasant-unpleasant axis but by the urgency of the stimulus.

“…Furthermore, some mothers are more susceptible to stressful experiences than other mothers based on individual characteristics such as genetic predisposition. Evidence suggests that the impact of childhood adversity on later parenting style is moderated by genetic variations in hormonal receptor expressions ( Fujiwara et al, 2019 , Hiraoka and Nomura, 2019 , Reichl et al, 2019 , Savelieva et al, 2019 , Senese et al, 2017 ). For example, mothers who experienced an overprotective parenting style in their childhood were more likely to exhibit a harsh parenting style with their own children if they carried the G allele on the oxytocin receptor gene ( Fujiwara et al, 2019 ).…”

How stress can influence brain adaptations to motherhood

Highlights The brain plasticity supports human mothers’ transition to parenthood. Stress can negatively influence maternal brain responses to infant cues. The maternal brain is affected by stress in childhood and the perinatal period. Altered responses to infant cues are associated with suboptimal parenting behaviors. Implications for intervention and directions for future work are discussed.

“…First, this study did not consider several individual difference, including childhood experiences, anxiety trait or childhood adversity—all of which can affect approach and avoidance behaviors (De Carli, Riem Madelon, & Parolin, ) and moderate the effect of cognitive load (Hiraoka & Nomura, ; Najmi, Amir, Frosio, & Ayers, ). It is possible that such individual differences may moderate the effect of cognitive load on postural and physiological responses to infant vocalization; therefore, future studies should examine the more comprehensive mechanism of mothers’ responses to infants’ emotional vocalizations by considering personal characteristics as an individual‐difference factor.…”

“…To manipulate cognitive load, participants were asked to memorize a meaningless alphabet string. This procedure has been used in previous research (Hiraoka & Nomura, , ). Before the presentation of each sound, a string of letters was presented on the PC display for 5 s. After the sound presentation, participants were asked to recall the meaningless alphabets string using the keyboard while remaining on the balance board.…”

“…Deater‐Deckard, Sewell, Petrill, and Thompson () found that negative reactions toward children was more predominant among mothers with poor working memory. In fact, previous studies have shown that empathy for crying infants decreases under high cognitive load (Hiraoka & Nomura, , ). These observations are supported by studies showing a reduction in neural areas involved in cognitive empathy control and executive function when participants experienced cognitive load while viewing others in distress (Rameson, Morelli, & Lieberman, ; Spunt & Lieberman, ).…”

Infants communicate their emotions to their caregivers through cries and laughter. Recent work suggests that adaptive parenting requires cognitive regulation of intuitive behaviors toward infants’ signals. In this study, we examined the effects of cognitive regulation on mothers’ unconscious behavioral and cardiac responses to infant cries and laughs. In all, 55 mothers took part in this study. To manipulate cognitive load, mothers were asked to memorize alphabet characters (two letters in the low cognitive load condition and eight in the high cognitive load condition). Then, they heard infant vocalizations (cries or laughs) for 6 s. During this time, we measured mothers’ behavioral (center of pressure, an index of approach–avoidance behavior) and physiological (heart rate) responses. Regardless of vocalization type (infant cries or laughs), high cognitive load increased mothers’ forward movement toward the infant sounds as well as mothers’ heart rate. These findings advance our understanding of the link between executive function and maternal response to infant signals by utilizing postural and physiological measures of maternal response during memory tasks that require cognitive resources.
