Children vary hugely in how demanding of their caregivers they are. This creates differences in demands on parents during observation, making the comparison of sensitivity between parents difficult. It would therefore be of interest to create standard situations in which all caregivers are faced with the same level of demand. This study developed an ecologically valid but standardized setting using an infant simulator with interactive features, the Leiden Infant Simulator Sensitivity Assessment (LISSA). The infant simulator resembles a real infant in appearance and it produces crying sounds that are life-like. The simulator begins with fussing and progresses to more intense crying in case of no care or inappropriate care. It responds by being calm again if appropriate care is given. One hundred and eighty-one female participants took care of the infant simulator for two evenings and in a 30 min lab session with increasing competing demands. Sensitive parenting behavior during the lab session was coded with the Ainsworth Sensitivity Scale. Sensitivity ratings covered the whole range of the scale (1-9), and were stable across settings (free play, competing demands). Sensitivity was related to an increase of positive affect during caretaking, and insensitivity was related to intended harsh caregiving response during a computerized cry paradigm. Sensitivity was unrelated to social desirability and self-reported quality of care given to the infant simulator. We discuss the potentials of the infant simulator for research on sensitive parenting, for preventive interventions, and for clinical practices.

Observation of parental sensitivity in a standard procedure, in which caregivers are faced with the same level of infant demand, enables the comparison of sensitivity between caregivers. We developed an ecologically valid standardized setting using an infant simulator with interactive features, the Leiden Infant Simulator Sensitivity Assessment (LISSA). The infant simulator resembles a real infant in appearance and crying sounds. In a previous study, we documented the LISSA's reliability and validity in a sample of 181 female undergraduate students (Voorthuis et al., 2013). In the current study, we tested the convergent validity in a sample of 34 mothers who were observed during free play with their own child as well as with the LISSA. Sensitive parenting behaviour was rated independently with the Ainsworth Sensitivity Scale (Ainsworth et al., 1974). Sensitivity with the LISSA was strongly correlated to sensitivity to the mother's own child, r = 0.53, p = 0.001. Mother-reported infant temperament was not associated with sensitivity to the mother's own child, and the mother's own infant's temperament did not moderate the correlation between sensitivity with the LISSA and sensitivity to the mother's own child. We discuss the potential of the infant simulator for research on sensitive parenting in parents and non-parents, for (prenatal) preventive interventions, and for clinical practices.

Parent-child agreement on child maltreatment was examined in a multigenerational study. Questionnaires on perpetrated and experienced child maltreatment were completed by 138 parent-child pairs. Multi-level analyses were conducted to explore whether parents and children agreed about levels of parent-to-child maltreatment (convergence), and to examine whether parents and children reported equal levels of child maltreatment (absolute differences). Direct and moderating effects of age and gender were examined as potential factors explaining differences between parent and child report. The associations between parent- and child-reported maltreatment were significant for all subtypes, but the strength of the associations was low to moderate. Moreover, children reported more parent-to-child neglect than parents did. Older participants reported more experienced maltreatment than younger participants, without evidence for differences in actual exposure. These findings support the value of multi-informant assessment of child maltreatment to improve accuracy, but also reveal the divergent perspectives of parents and children on child maltreatment.

The neuropeptide oxytocin plays an important role in mother–infant bonding. However, recent studies indicate that the effects of oxytocin on prosociality are dependent on perceived social context. Using functional magnetic resonance imaging, we examined differential effects of intranasally administered oxytocin on neural responding to 500 and 700 Hz crying that was indicated as emanating from a sick infant and 500 and 700 Hz crying emanating from a bored infant. We found that oxytocin significantly increased insula and inferior frontal gyrus responding to sick infant crying, but decreased activation in these brain regions during exposure to crying of an infant that was labeled as bored. In addition, oxytocin decreased amygdala responding to 500 Hz crying, but increased amygdala responding to 700 Hz crying. These findings indicate that labeling the same infant crying as 'sick' or as 'bored' drastically changes neural activity in response to intranasal oxytocin administration. Oxytocin increases empathic reactions to sick infants' crying, but lowers the perceived urgency of crying of an infant perceived as bored, thus flexibly adapting adult responses to infant crying labeled in various ways.
