| dc.description.abstract | Infants’ experiences of caregiver attunement and regulatory support in the first months of life likely shape embodied expectations about the self, the caregiver, and the extent to which the emerging attachment relationship can transform and soothe distress. Infants’ biobehavioral responses to the Still-Face Paradigm (SF) offer a potential index of these emerging expectations, with potential implications for understanding precursors to later quality of attachment and the origins and malleability of these precursors in early development. This dissertation adopts a programmatic and integrative approach to evaluating the possibility that infant responses to the Still-Face paradigm are meaningfully indicative of dyadic adjustment during the infant’s first year of life and potentially prognostic of quality of attachment in the infant’s second year. To this end, the introduction to the dissertation describes (1) the theoretical and empirical rationale for regarding infant SF response as a marker of the infant’s interactive history and (2) the importance that identification of attachment-like regulatory patterns or precursors to later quality of attachment in the SF may have for the study of infant adaptation and long-term health. The dissertation’s second chapter consists of a narrative review of existing efforts to glean attachment-like patterns or otherwise predict later quality of attachment on the basis of infants’ SF response. The narrative review details discrete affective and regulatory behaviors in the SF that have received attention as possible markers of infants’ attachment-related working models in-the-making; the review identifies overlap and discrepancies among existing microanalytic findings. While modest associations between infant SF behaviors and attachment outcomes point to the promise of the SF paradigm as a source of information about dyadic adjustment and attachment in the making, discrepancies across microanalytic studies of discrete behaviors (including among infants at different ages) and differences in measurement strategies exemplify the need for programmatic, synthesizing efforts to facilitate comparison of findings between studies. The narrative review also draws on the development of the attachment classificatory system to advocate for an approach to individual differences in the SF that attends to organized patterns of regulatory behavior rather than discrete behaviors. The subsequent chapters of this dissertation examine proximal and distal correlates to infant regulatory responses in the SF, by way of three sub-studies of a single sample of mother-infant dyads contending with socioeconomic and other psychosocial risk. Each of the three sub-studies make use of archived recordings of the SF paradigm and leverage secondary analysis of several related measures that were collected in an already-completed study that predated the dissertation. Study 1 adopts a novel but existing typological approach to identifying organized patterns of infant regulatory behavior in the SF, to in turn compare the distribution of the patterns in the present sample to that of other samples that have applied a similarly categorical approach. Study 1 also (a) examines evidence for convergent validity of the regulatory patterns by juxtaposing the patterns with more granular approaches to observing and describing infant SF behavior, and (b) evaluates the hypothesis that patterning of infant regulatory behavior reflects features of the infant’s interactive history. Study 2 examines whether patterns of regulatory behavior are accompanied by differences in infants’ autonomic (specifically, heart rate and respiratory sinus arrhythmia) responses to the SF stressor. Finally, Study 3 seeks to replicate an existing finding of association between SF regulatory patterns and later organized attachment classification. Studies 1 and 2 find evidence of convergent validity of the regulatory patterns, which exhibit expected associations with more granular observations of infant behavior, maternal sensitivity to infant distress, and differential changes in infant heart rate during the SF paradigm. While several hypothesized associations between infants’ SF-based regulatory patterns and concurrent measures bear out in the present study, the regulatory patterns observed in the SF paradigm in this sample at five months postpartum are not associated with later organized quality of attachment assessed in the Strange Situation Procedure one year later. Connections to current findings are discussed, as are recommendations for future study of organized patterns of regulatory behavior and attachment in the making. | en_US |
