The Maturational Processes and the Facilitating Environment

Although theories of early social development emphasize the advantage of mother-infant rhythmic coupling and bidirectional coordination, empirical demonstrations remain sparse. We therefore test the hypothesis that vocal rhythm coordination at age 4 months predicts attachment and cognition at age 12 months. Partner and site novelty were studied by recording mother-infant, stranger-infant, and mother-stranger face-to-face interactions in both home and laboratory sites for 88 4-month-old infants, for a total of 410 recordings. An automated dialogic coding scheme, appropriate to the nonperiodic rhythms of our data, implemented a systems concept of every action as jointly produced by both partners. Adult-infant coordination at age 4 months indeed predicted both outcomes at age 12 months, but midrange degree of mother-infant and stranger-infant coordination was optimal for attachment (Strange Situation), whereas high ("tight") stranger-infant coordination in the lab was optimal for cognition (Bayley Scales). Thus, high coordination can index more or less optimal outcomes, as a function of outcome measure, partner, and site. Bidirectional coordination patterns were salient in both attachment and cognition predictions. Comparison of mother-infant and stranger-infant interactions was particularly informative, suggesting the dynamics of infants' early differentiation from mothers. Stranger and infant showed different patterns of vocal rhythm activity level, were more bidirectional, accounted for 8 times more variance in Bayley scores, predicted attachment just as well as mother and infant, and revealed more varied contingency structures and a wider range of attachment outcomes. To explain why vocal timing measures at age 4 months predict outcomes at age 12 months, our dialogue model was construed as containing procedures for regulating the pragmatics of proto-conversation. The timing patterns of the 4-month-olds were seen as procedural or performance knowledge, and as precursors of various kinesic patterns in the outcomes of 12-month-olds. Thus, our work further defines a fundamental dyadic timing matrix--a system that guides the trajectory of relatedness, informing all relational theories of development.

Rhythms of Dialogue in Infancy: Coordinated Timing in Development.

Self-destructive behavior in current society promotes a search for psychobiological factors underlying this epidemic. Perinatal brain plasticity increases the vulnerability to early adverse experiences, thus leading to abnormal development and behavior. Although several epidemiological investigations have correlated perinatal and neonatal complications with abnormal adult behavior, our understanding of the underlying mechanisms remains rudimentary. Models of early experience, such as repetitive pain, sepsis, or maternal separation in rodents and other species have noted multiple alterations in the adult brain, correlated with specific behavioral phenotypes depending on the timing and nature of the insult. The mechanisms mediating such changes in the neonatal brain have remained largely unexplored. We propose that lack of N-methyl-D-aspartate (NMDA) receptor activity from maternal separation and sensory isolation leads to increased apoptosis in multiple areas of the immature brain. On the other hand, exposure to repetitive pain may cause excessive NMDA/excitatory amino acid activation resulting in excitotoxic damage to developing neurons. These changes promote two distinct behavioral phenotypes characterized by increased anxiety, altered pain sensitivity, stress disorders, hyperactivity/attention deficit disorder, leading to impaired social skills and patterns of self-destructive behavior. The clinical important of these mechanisms lies in the prevention of early insults, effective treatment of neonatal pain and stress, and perhaps the discovery of novel therapeutic approaches that limit neuronal excitotoxicity or apoptosis.

The Origins of 12-Month Attachment: A Microanalysis of 4-Month Mother-Infant Interaction

Developmental psychology and psychopathology has in the past been more concerned with the quality of self-representation than with the development of the subjective agency which underpins our experience of feeling, thought and action, a key function of mentalisation. This review begins by contrasting a Cartesian view of pre-wired introspective subjectivity with a constructionist model based on the assumption of an innate contingency detector which orients the infant towards aspects of the social world that react congruently and in a specifically cued informative manner that expresses and facilitates the assimilation of cultural knowledge. Research on the neural mechanisms associated with mentalisation and social influences on its development are reviewed. It is suggested that the infant focuses on the attachment figure as a source of reliable information about the world. The construction of the sense of a subjective self is then an aspect of acquiring knowledge about the world through the caregiver's pedagogical communicative displays which in this context focuses on the child's thoughts and feelings. We argue that a number of possible mechanisms, including complementary activation of attachment and mentalisation, the disruptive effect of maltreatment on parent-child communication, the biobehavioural overlap of cues for learning and cues for attachment, may have a role in ensuring that the quality of relationship with the caregiver influences the development of the child's experience of thoughts and feelings.

The parent-infant dyad and the construction of the subjective self

Using research on the purely social face‐to‐face exchange, we examine patterns of mother—infant interaction and their relevance for the presymbolic origins of self and object representations, focusing on the representation of inter‐relatedness between self and object. Based on a dyadic systems view in which the system is defined by both self‐ and interactive‐regulation processes, we argue that characteristic patterns of self and interactive regulation form early interaction structures, which provide an important basis for emerging self and object representations. What will be represented, presymbolically, is the dynamic interactive process itself, the interplay, as each partner influences the other from moment to moment. This is a dynamic, process view of “interactive”; or “dyadic”; representations. The argument that early interaction structures organize experience is based on a transformational model in which there are continuous transformations and restructurings, where development is in a constant stat...

Mother—infant interaction structures and presymbolic self‐ and object representations

A microanalysis of 4-month mother-infant face-to-face communication predicted 12-month infant disorganized (vs. secure) attachment outcomes in an urban community sample. We documented a dyadic systems view of the roles of both partners, the roles of both self- and interactive contingency, and the importance of attention, orientation and touch, and as well as facial and vocal affect, in the co-construction of attachment disorganization. The analysis of different communication modalities identified striking intrapersonal and interpersonal intermodal discordance or conflict, in the context of intensely distressed infants, as the central feature of future disorganized dyads at 4 months. Lowered maternal contingent coordination, and failures of maternal affective correspondence, constituted maternal emotional withdrawal from distressed infants. This maternal withdrawal compromises infant interactive agency and emotional coherence. We characterize of the nature of emerging internal working models of future disorganized infants as follows: Future disorganized infants represent states of not being sensed and known by their mothers, particularly in moments of distress; they represent confusion about both their own and their mothers' basic emotional organization, and about their mothers' response to their distress. This internal working model sets a trajectory in development which may disturb the fundamental integration of the person. The remarkable specificity of our findings has the potential to lead to more finely-focused clinical interventions.
