Infant brain responses to live face-to-face interaction with their mothers: Combining functional near-infrared spectroscopy (fNIRS) with a modified still-face paradigm

BackgroundNon-invasive imaging techniques, such as fNIRS, allow us to shed light on the neural correlates of infant’s social-emotional development within the context of parent-infant interaction. On a behavioral level, numerous studies have investigated parent-infant interaction employing the still-face paradigm and found that the primary caregiver(s), often the mother, is an important coregulator of the infant’s physiological and behavioral stress response. However, limited information is available on how the infant’s brain reacts to the maternal cues during real-life interaction.MethodsTherefore, the main aim of the current study was to design a fNIRS paradigm to study live mother-infant interaction and to explore the neural correlates of infant affect regulation during real-life dyadic interaction. To this end, a modified still-face paradigm was designed, which consists of live face-to-face mother-infant, and stranger-infant, interaction episodes, including stressful, “still-face” and non-stressful, “happy-face” interaction blocks, combined with infant fNIRS imaging.ResultsHemodynamic brain responses were collected in n = 10 (6 females, mean age 230.2 ± 17.5 days), typically developing infants using the Hitachi ETG-4000 continuous-wave system (22 channels spanning the frontal cortex; 10 Hz system sampling frequency). Infants with usable data (n = 7) showed negative activations, indicated by a decrease in oxygenated hemoglobin, over the middle frontal gyrus in response to happy-face (reunion) interaction with their mothers compared to a female stranger; suggesting deactivation of brain regions associated with affect regulation. We also explored correlations between infant brain responses to maternal interaction and infant characteristics (temperament) as well as experiential/environmental factors (mothers’ self-reported depression symptoms).ConclusionsAlthough the current results are very preliminary, they overall suggest that live design in infant populations is doable and offers unique opportunities to study the neural mechanisms underlying early caregiver(s)-child interaction in a more naturalistic context. Restrictions, and implications, of the methodology are critically discussed.     

Contrasting behavioral looking procedures: a case study on infant speech segmentation

This paper compared three different procedures common in infant speech perception research: a headturn preference procedure (HPP) and a central-fixation (CF) procedure with either automated eye-tracking (CF-ET) or manual coding (CF-M). In theory, such procedures all measure the same underlying speech perception and learning mechanisms and the choice between them should ideally be irrelevant in unveiling infant preference. However, the ManyBabies study (ManyBabies Consortium, 2019), a cross-laboratory collaboration on infants’ preference for child-directed speech, revealed that choice of procedure can modulate effect sizes. Here we examined whether procedure also modulates preference in paradigms that add a learning phase prior to test: a speech segmentation paradigm. Such paradigms are particularly important for studying the learning mechanisms infants can employ for language acquisition. We carried out the same familiarization-then-test experiment with the three different procedures (32 unique infants per procedure). Procedures were compared on various factors, such as overall effect, average looking time and drop-out rate. The key observations are that the HPP yielded a larger familiarity preference, but also reported larger drop-out rates. This raises questions about the generalizability of results. We argue that more collaborative research into different procedures in infant preference experiments is required in order to interpret the variation in infant preferences more accurately.     

Non-directive play therapy as a means of recreating optimal infant socialization patterns

The paper proposes that non-directive play therapy recreates conditions similar to those created between a carer and infant during normal development. By the heightening in therapy of essentially normal developmental processes the child with harmful or inadequate relationship experiences is enabled to rework and reintegrate these into normal interactiv patterns. Ways are reviewed in which non-directive play therapy exemplifies important attachment properties in an individual's primary relationships, and recreates healthy carer-infant patterns of interaction such as topicsharing, face-to-face interactions, mutuality and symbolic play, in order to bring about therapeutic change. This primary corrective function is similar to other responsive therapeutic approaches, but it is argued that a particular strength of non-directive play therapy lies in its inherent flexibility and responsiveness to the individual child, which resembles normal infant socialization with a sensitive carer.     

A decolonial perspective of collective coping in the adult attachment and life satisfaction link

This study examined the role of cognitive flexibility and collective coping in the relationship between adult attachment and life satisfaction while comparing Black, Indigenous, and People of Color (BIPOC; n = 187) and White (n = 135) groups. Result showed that the relationship between attachment anxiety and life satisfaction was mediated via cognitive flexibility and collective coping only in the BIPOC group. This study informs culturally responsive attachment-based counseling and advances literature from a decolonial perspective.     

Effects of Attachment Style on Preferences for and Satisfaction with Different Employment Contracts: An Exploratory Study

Based on the characteristics of three attachment styles—secure, anxious/ambivalent, and avoidance—hypotheses were derived for differences between them with regard to preferences for three employment relationships differing in whether employees are internal—hired and paid by an organization or external—employed through software houses. In addition, hypotheses were also drawn for differences in overall and facet work satisfaction. The sample consisted of computer science students of whom a large proportion have also been working in that field, and individuals employed as software engineers. Anxious/ambivalents were relatively higher in preference for the external contract and lower in preference for the internal contract, as compared to the two other styles. Contrary to the hypotheses, the avoidants did not differ from the secure style in expressing the highest preference to the internal permanent contract and the lowest to the external contract. Work satisfaction was highest among the secure style but contrary to hypotheses, the anxious/ambivalent group did not differ significantly from that group concerning overall, intrinsic, and extrinsic satisfaction. The avoidants were lowest on those measures. Findings are discussed in light of the different attachment styles and the unique features of the high-tech industry.     

Relationships between attachment behavior in the laboratory and the caretaking environment

How useful are observations of patterns of attachment behavior in a structured laboratory setting for making inferences about the quality of caretaking received by an infant in the home environment? To address this question a sample of 107 12-month-old infants who had participated in a longitudinal intervention project beginning before birth through 14 months of age were observed in a structured laboratory setting. Patterns of attachment behavior were compared to maternal caretaking variables observed in the home environment as well as to ratings of the quality of the infants' play. The results indicated that attachment behavior in the laboratory can be used to make inferences about the quality of caretaking in the home environment with confidence when a consistent and unambiguous pattern of either optimal or problematical attachment behavior is present, but not when the attachment behavior pattern is inconsistent or ambiguous.

Attachment as an Integrating Concept in Couple and Family Therapy: Some Considerations with Special Reference to South Africa

Couples, marital, and family therapy in South Africa and throughout the world have undergone radical changes in theory and practice in the last three to four decades. These developments are seen in the emergence of different approaches which may be regarded as modern or post-modern, intrapsychic or systemic. While these different approaches are often seen as theoretically and clinically incompatible, it is the aim in this paper to suggest that the time has come to seek points of integration of these different approaches, and the construct of attachment is proposed as an ideal integrating concept. Two case illustrations are used to demonstrate attachment as an integrating concept. It is suggested that the concept of attachment may also be applied to family therapists and associations, including and especially in South Africa.
