Investigating the effects of perinatal status and gender on adults' responses to infant and adult facial emotion.

The perception of emotion in infant faces is a key parental skill, thought to be impacted by caregiving experience. It is widely assumed that women, and in particular mothers in the postnatal period, are more attuned to infant facial expressions than men. However, empirical evidence for this is lacking, and it is not yet clear whether potential differences in emotion processing between adults during pregnancy and postnatally are specific to infant expressions or extend to faces of all ages. In this cross-sectional study using a subsample from a Finnish birth cohort (N = 610), we examine adult and infant facial expression perception in pre- and postnatal men and women. Women rated the happy infant faces more positively on the valence (pleasure) dimension than men, but men rated the faces higher on the arousal (excited) dimension. There were no significant differences between adults responding during pregnancy or postnatally, but first-time mothers rated the faces as higher in arousal overall than multiparous mothers. The ability to identify specific emotions (e.g., sadness) in adult faces correlated with judgments of emotion in similarly valenced infant faces. We conclude that adults differ in their sensitivity to positive or negative emotions, independent of whether they are expressed in infant or adult faces. We did not find that perinatal status (pre- or postnatal) was associated with differences in sensitivity to emotion in infant or adult faces. Men and women were differentially sensitive to the valence and arousal in infant faces, independent of the timing of their responses. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Maternal Anxiety Symptoms and Self-Regulation Capacity Are Associated With the Unpredictability of Maternal Sensory Signals in Caregiving Behavior.

The unpredictability of maternal sensory signals in caregiving behavior has been recently found to be linked with infant neurodevelopment. The research area is new, and very little is yet known, how maternal anxiety and depressive symptoms and specific parental characteristics relate to the unpredictable maternal care. The aims of the current study were to explore how pre- and postnatal maternal anxiety and depressive symptoms and self-regulation capacity associate with the unpredictability of maternal sensory signals. The study population consisted of 177 mother-infant dyads. The unpredictability of the maternal sensory signals was explored from the video-recorded mother-infant free play situation when the infant was 8 months of age. Pre- and postnatal anxiety and depressive symptoms were measured by questionnaires prenatally at gwks 14, 24, 34, and 3 and 6 months postpartum. Maternal self-regulation capacity, a trait considered to be stable in adulthood, was assessed using adult temperament questionnaire when the infant was 12 months of age. We found that elevated prenatal maternal anxiety symptoms associated with higher unpredictability in the maternal care while depressive symptoms were unrelated to the unpredictability of maternal care. Moreover, the association was moderated by maternal self-regulation capacity, as higher anxiety symptoms during pre-and postnatal period were associated more unpredictability among the mothers with low self-regulation capacity. The combination of higher amount of maternal anxiety symptoms and lower self-regulation capacity seems to constitute specific risk for the unpredictable maternal care.

Across continents and demographics, unpredictable maternal signals are associated with children's cognitive function.

BACKGROUND: Early life experiences have persisting influence on brain function throughout life. Maternal signals constitute a primary source of early life experiences, and their quantity and quality during sensitive developmental periods exert enduring effects on cognitive function and emotional and social behaviors. Here we examined if, in addition to established qualitative dimensions of maternal behavior during her interactions with her infant and child, patterns of maternal signals may contribute to the maturation of children's executive functions. We focused primarily on effortful control, a potent predictor of mental health outcomes later in life. METHODS: In two independent prospective cohorts in Turku, Finland (N = 135), and Irvine, CA, USA (N = 192) that differed significantly in race/ethnicity and sociodemographic parameters, we assessed whether infant exposure to unpredictable patterns of maternal-derived sensory signals portended poor effortful control. OUTCOMES: In both the Irvine and Turku cohorts, unpredictable sequences of maternal behavior during infancy were associated with worse effortful control at one year of age. Longitudinal analyses demonstrated that this association persisted for as long as each cohort was assessed-until two years of age in the Turku cohort and to 9.5 years in the Irvine cohort. The relation of unpredictable maternal signals during infancy and the measures of executive function persisted after adjusting for covariates. INTERPRETATIONS: The consistency of our findings across two cohorts from different demographic backgrounds substantiated the finding that patterns, and specifically unpredictable sequences, of maternal behaviors may influence the development of executive functions which may be associated with vulnerability to subsequent psychopathology.

How maternal pre- and postnatal symptoms of depression and anxiety affect early mother-infant interaction?

BACKGROUND: Maternal pre- and postnatal psychological distress, such as anxiety and depression, may negatively affect mother-infant interaction quality. However, more information is needed on the role of specific types and timings of pre- and postnatal distress symptoms on mother-infant interaction. Research on the role of maternal anxiety is especially scarce. METHODS: We examined whether maternal pregnancy- related anxiety (gestational weeks 24 and 34), general anxiety or depressive symptoms (gw 14, 24 and 34 and at the infant age of 3 and 6 months) associate with the quality of mother-infant interaction when the child is eight months old. Maternal symptoms (N = 190) were measured with EPDS, SCL-90 anxiety subscale and PRAQ-R2. Mother-infant interaction was measured with the Emotional Availability Scales (EAS). RESULTS: After controlling for background factors, general anxiety at the 3rd pregnancy trimester was associated with higher maternal intrusiveness in EAS. Depressive symptoms at 6 months postpartum associated with lower maternal structuring behavior and with the child's lower involvement of the mother. LIMITATIONS: A very small number of mothers with severe symptoms of depression and anxiety. CONCLUSIONS: Prenatal anxiety and postnatal depressive symptoms may each have unique effects on the different areas of mother-infant interaction, suggesting the need to develop more targeted interventions for mothers with different symptom profiles and timings. Prenatally anxious mothers could potentially benefit from early interventions decreasing stress and anxiety symptoms and specifically promoting their ability to read infant cues appropriately. Infants of postnatally depressed mothers may need interventions where both members of the dyad receive help.

Brain oscillatory responses to an auditory-verbal working memory task in mild cognitive impairment and Alzheimer's disease.

We report preliminary findings on EEG oscillatory correlates of working memory in mild cognitive impairment (MCI) and Alzheimer's disease (AD). Event-related desynchronization (ERD) and synchronization (ERS) of the 1-20 Hz EEG frequencies were studied using wavelet transforms in elderly controls, MCI patients and mild probable AD patients performing an auditory-verbal Sternberg memory task. Behaviourally, the AD patients made more errors than the controls and the MCI group. Statistically significant differences during the encoding of the memory set were found between the controls and the MCI group, such that the latter group showed ERD in the approximately 10-20 Hz frequencies. The findings may reflect different, compensatory encoding strategies in MCI. During retrieval, the most obvious differences were observed between the controls and the AD group: the ERD in the approximately 7-17 Hz frequencies was absent in the AD group particularly in anterior and left temporal electrode locations. This finding might indicate that AD is associated with deficient lexical-semantic processing during the retrieval phase in working memory tasks. Future studies with larger patient groups are needed to establish the diagnostic value of ERD/ERS patterns in MCI and AD.
