Stressed parents: a dyadic perspective on perceived infant temperament

The study employed the actor–partner interdependence model (APIM) to test whether one parent's experiences of recent life events as more stressful (the PSS) are associated with the same parent's own (the actor effect) and the other parent's (the partner effect) perceptions of the infant temperament as more negatively and/or less positively tuned (the IBQ; n=584 parents, 292 dyads). The results indicated that the more stress one parent reported the more negatively tuned were the same parent's own, and the other parent's perceptions of the infant. Perceptions of the infant temperament were least positive for members of parent dyads who were more, relative to less, similar in the experienced stress. The associations were independent of the parent gender and the parent‐reported level of trait anxiety. The findings augment prior knowledge on the factors that steer parental perceptions, and suggest that the dyadic perspective may offer valuable insight into the dynamics of interacting within a family consisting of two biological parents and an infant.

Parent–Infant Synchrony: Biological Foundations and Developmental Outcomes

ABSTRACT— Synchrony—a construct used across multiple fields to denote the temporal relationship between events—has been applied to the study of mother–infant interaction and is suggested here as a framework for the study of interpersonal relationships. Defined as the temporal coordination of micro-level social behavior, parent–infant synchrony is charted in its development across infancy from the initial consolidation of biological rhythms during pregnancy to the emergence of symbolic exchange between parent and child. Synchrony is shown to depend on physiological mechanisms supporting bond formation in mammals—particularly physiological oscillators and neuroendocrine systems such as those involving the hormone oxytocin. Developmental outcomes of the synchrony experience are observed in the domains of self-regulation, symbol use, and the capacity for empathy across childhood and adolescence. Specific disruptions to the parameters of synchrony that may be observed in various pathological conditions, such as prematurity or maternal affective disorder, are detailed. A time-based, micro-analytic behavioral approach to the study of human relationship may offer new insights on intersubjectivity across the lifespan.

'Talk to me baby, tell me what's the matter now': Semiotic and developmental perspectives on communication in psychoanalytic infant treatment

Infants suffer to a considerable degree from disturbances in nursing, sleep, mood, and attachment. Psychotherapeutic methods are increasingly used to help them. According to case reports, psychoanalytic work with infants and mothers has shown deep‐reaching and often surprisingly rapid results, both in symptom reduction and in improved relations between mother and child. The clinical urgency of the method makes it important to study its results and theoretical underpinnings. Among the theoretical issues often raised in discussions on this modifi ed form of psychoanalysis, those addressing the nature of communication between analyst, baby, and the mother are the most frequent. For example, how and what does an infant understand when the analyst interprets to her? What does the analyst understand of the infant's communication? These issues are addressed by investigating the infant's tools for understanding linguistic and emotional communication, and by providing a semiotic framework for describing the communication between the three participants in the analytic setting. The paper also investigates problems with the traditional ways of using the concept of symbolization within psychoanalytic theory. The theoretical investigation is illustrated by two brief vignettes from psychoanalytic work with an 8 month‐old girl and her mother. demand for the breast. Like the two lovers in the blues, they seemed to be slaves to     

Semiotic transformations in psychoanalysis with infants and adults

The author addresses issues that emerge when we compare psychoanalytic experiences with adults and with infants. Two analyses-one with a 35 year-old woman and one with a 2 week-old boy and his mother-illustrate that infant psychoanalytic experiences help us understand and handle adult transference. However, we cannot extrapolate infant experiences to adult work. Truly, witnessing the baby's communication widens our sensitivity to non-verbal layers of the adult's communication. Infant work also offers a direct encounter with the container and the contained personified by a mother with her baby. But we need to conceptualize carefully the links between clinical experiences with babies and adults. When we call an adult transference pattern 'infantile', we imply that primeval experience has been transformed into present behaviour. However, if we view the analytical situation as one in which infantile invariants have transformed into adult symptoms, we face the impossible task of indicating the roots of the present symptoms. The author rather suggests that what is transformed is not an invariant infantile essence but signs denoting the patient's inner reality. He proposes we define transformation as a semiotic process instead of building it on an essentialist grounding. If we view the analytic situation as a map of signs that we translate during our psychoanalytic work, we can proceed into defining containment as a semiotic process. This idea will be linked with a conceptualization of the mother-infant relation in semiotic terms.     

Infant observation: A range of questions and challenges for contemporary psychoanalysis1

The author attempts to integrate several perspectives within the field of infant observation that reflect the analyst's personal experience as a clinician, as a professor at the analytic institute and as a researcher in the field of psychoanalysis. Can infant observation contribute to analytic technique, theory and training? If so, what would be the nature of such contribution? To answer these questions, the author reviews the literature on infant observation from Freud to the present, highlighting Latin American contributions to this subject. She makes reference to the role of technological innovations, which have allowed videotaping, repeated observations, temporal segmentation and computerized programs, thus giving rise to microanalytic research. This discussion prompts the question about the contributions made by systematic research to clinical practice. To tackle this question, the author presents both a clinical vignette taken from her personal experience, and the current debate on this subject as it appears in the work of Daniel Stern and André Green. Finally, she presents some conclusions that are part of an ongoing debate in the psychoanalytic field.     

Eye movements during spoken word recognition in Russian children

This study explores incremental processing in spoken word recognition in Russian 5- and 6-year-olds and adults using free-viewing eye-tracking. Participants viewed scenes containing pictures of four familiar objects and clicked on a target embedded in a spoken instruction. In the cohort condition, two object names shared identical three-phoneme onsets. In the noncohort condition, all object names had unique onsets. Coarse-grain analyses of eye movements indicated that adults produced looks to the competitor on significantly more cohort trials than on noncohort trials, whereas children surprisingly failed to demonstrate cohort competition due to widespread exploratory eye movements across conditions. Fine-grain analyses, in contrast, showed a similar time course of eye movements across children and adults, but with cohort competition lingering more than 1s longer in children. The dissociation between coarse-grain and fine-grain eye movements indicates a need to consider multiple behavioral measures in making developmental comparisons in language processing.

Reduced misinformation effects following saccadic bilateral eye movements

The effects of saccadic bilateral (horizontal) eye movements on memory for a visual event narrative were investigated. In the study phase, participants were exposed to a set of pictures accompanied by a verbal commentary describing the events depicted in the pictures. Next, the participants were asked either misleading or control questions about the depicted event and were then asked to engage in 30s of bilateral vs. vertical vs. no eye movements. Finally, recognition memory was tested using the remember-know procedure. It was found that bilateral eye movements increased true memory for the event, increased recollection, and decreased the magnitude of the misinformation effect. The findings are discussed in terms of source monitoring, dual-process theories of memory and the potential neural foundations of such effects.     

Bobwhite quail (Colinus virginianus) hatchlings track the direction of human gaze

Gaze following allows individuals to detect the locus of attention of both conspecifics and other species. However, little is known about how this ability develops. We explored the emergence of bobwhite quail hatchlings’ ability to track human gaze by assessing their avoidance behavior in an open arena under five testing conditions: (1) a Direct Gaze condition, in which an experimenter looking down was positioned above one of two approach areas; (2) a Gaze Follow condition in which an experimenter, positioned equidistant between two approach areas, directed his/her gaze towards one of the areas; (3) a Masked Gaze Follow condition, in which the experimenter wore a mask during the Gaze Follow test; (4) a Deprived Face Experience condition, in which hatchlings were deprived of experience with human faces prior to the Gaze Follow test; and (5) a Control condition in which no experimenter was present during testing. Results revealed that hatchlings from the Direct Gaze condition preferred the non-gazed approach area at all ages tested. Hatchlings from the Gaze Follow condition preferred the non-gazed approach area at 48 and 72 h, but not at 24 h of age. In contrast, hatchlings from the Masked Gaze Follow, Deprived Face and Control conditions did not prefer either approach area at any age tested. These results indicate that experience with human faces plays a key role in the rapid emergence of gaze following behavior in bobwhite quail hatchlings.
