ON BECOMING ABLE TO PLAY: INDIVIDUAL CHILD PSYCHOANALYTIC PSYCHODRAMA AND THE DEVELOPMENT OF SYMBOLIZATION

In this paper, the authors analyze the relevance and transformative potential of individual psychoanalytic psychodrama in the treatment of children with severe impairments in symbolization. Central features of this modality, including promoting the representation of early traumatic experiences, are presented and discussed. Specific features include double‐envelope containment of the co‐therapists’ group and play leader, consequent diffraction of the transference‐determining portrayal, gradual integration, and initial figuration of coexisting split‐off fragments. Drawing on in‐depth clinical material, the authors show how psychodrama tempers the potentially traumatic effects of the encounter with the object, allowing these patients to access the transitional area of play.     

The topography of the uncanny valley and individuals’ need for structure: A nonlinear mixed effects analysis

The uncanny valley hypothesis suggests that robots that closely resemble humans elicit feelings of eeriness. We focused on individual differences in the uncanny valley experience, which have been largely neglected to date. Using a mixed effects modelling approach, we tested whether individual differences in the need for structure predict uncanny valley sensitivity. Two experiments (Ns = 226 and 336) with morphed stimuli confirmed the uncanny valley effect. A moderator effect of need for structure was found in Experiment 2, which used a fine-grained manipulation of human likeness, but not in Experiment 1, which used a 3-step manipulation. The results provide tentative evidence that individuals who respond negatively to a lack of structure show a more pronounced (“deeper”) uncanny valley effect.     

Through babies’ eyes: Practical and theoretical considerations of using wearable technology to measure parent–infant behaviour from the mothers’ and infants’ view points

AimsTo explore the utility of first-person viewpoint cameras at home, for recording mother and infant behaviour, and for reducing problems associated with participant reactivity, which represent a fundamental bias in observational research.MethodsWe compared footage recording the same play interactions from a traditional third-person point of view (3rd PC) and using cameras worn on headbands (first-person cameras [1st PCs]) to record first-person points of view of mother and infant simultaneously. In addition, we left the dyads alone with the 1st PCs for a number of days to record natural mother–child behaviour at home. Fifteen mothers with infants (3–12 months of age) provided a total of 14 h of footage at home alone with the 1st PCs.ResultsCodings of maternal behaviour from footage of the same scenario captured from 1st PCs and 3rd PCs showed high concordance (kappa >0.8). Footage captured by the 1st PCs also showed strong inter-rater reliability (kappa = 0.9). Data from 1st PCs during sessions recorded alone at home captured more ‘negative’ maternal behaviours per min than observations using 1st PCs whilst a researcher was present (mean difference = 0.90 (95% CI 0.5–1.2, p < 0.001 representing 1.5 SDs).Conclusion1st PCs offer a number of practical advantages and can reliably record maternal and infant behaviour. This approach can also record a higher frequency of less socially desirable maternal behaviours. It is unclear whether this difference is due to lack of need of the presence of researcher or the increased duration of recordings. This finding is potentially important for research questions aiming to capture more ecologically valid behaviours and reduce demand characteristics.     

Development of mother–infant interaction in tickling play: The relationship between infants’ ticklishness and social behaviors

This study examined the development of mother–infant tickling interaction and the relationship between infants’ ticklishness and social behaviors including infants’ looking at mothers’ face, mothers’ narrative tickling, and mothers’ laughter. Twenty-two Japanese infants aged 5 months (n = 10, five girls) and 7 months (n = 12, four girls) and their mothers were videotaped. Results revealed that the mothers’ narrative tickling was more frequent at 7 than at 5 months and the infants’ strong ticklishness showed the same tendency. The infants’ strong ticklishness was linked with the occurrence of other social behaviors. In conclusion, infants’ ticklishness was heavily connected with social behaviors. The mode of the tickling interaction at 7 months was different from that at 5 months especially in the increase of mother’s narrative tickling. A possible function of such mother’s narrative tickling to facilitate infant active communication at a higher cognitive level including anticipation, was discussed.     

IMPACT OF JOINT ATTENTION ON SOCIAL‐COMMUNICATION SKILLS IN INTERNATIONALLY ADOPTED CHILDREN

Internationally adopted (IA) children have often experienced early adversity and are at risk for long‐term deficiencies in multiple developmental domains. This study examined the association between IA children's joint attention (JA) soon after arrival and later cognitive, communicative, and socioemotional competency 6 months’ postadoption. We expected a child's initial JA would positively predict later cognitive, communication, and social ability. IA children (n = 63) adopted from Eastern Europe were seen soon after their arrival into the United States to assess their JA. Their socioemotional competency, social communication, and cognitive abilities were measured at a follow‐up session 6 months’ postadoption. We found that higher order JA was positively associated with measures of social relatedness. Furthermore, individual hierarchical regressions of each measure of JA (higher order JA, initiating JA, responding to JA, and initiating behavior requests [BR]) considered with age‐at‐adoption showed that each measure was an independent and positive predictor of Mullen outcomes in the receptive and expressive language domains. These results suggest that JA may be a sensitive predictor of subsequent functioning in the social, communicative, and cognitive domains. Thus, assessing JA soon after arrival has the potential to identify at‐risk IA children, and interventions targeting JA may support those children in overcoming the negative impacts of early adversity.     

MOTHER–CHILD AND FATHER–CHILD PLAY INTERACTION: THE IMPORTANCE OF PARENTAL PLAYFULNESS AS A MODERATOR OF THE LINKS BETWEEN PARENTAL BEHAVIOR AND CHILD NEGATIVITY

Based on the premise that father–child play is an important context for children's development and that fathers “specialize” in play, similarities and differences in the role of playfulness in the father–child and mother–child relationship were examined. Participants in this study included 111 families (children's age: 1–3 years). Father–child and mother–child play interactions were videotaped and coded for parental playfulness, sensitivity, structuring, and nonintrusiveness as well as child negativity. Results indicated that mothers and fathers did not differ in playfulness and that mothers and fathers who were higher in playfulness had children with lower levels of negativity. However, playfulness differently moderated the links between parents’ and children's behaviors for mothers and fathers. A double‐risk pattern was found for mothers, such that the links between child negativity and maternal sensitivity, structuring, and nonintrusiveness were significant only for the subgroup of mothers with low levels of playfulness. When mothers had high levels of playfulness, these effects were negligible. For fathers, a double‐buffer pattern was revealed, indicating that the links between child negativity and paternal sensitivity and structuring were significant only for fathers with high levels of playfulness. When fathers had low levels of playfulness, these effects were negligible. These findings demonstrate the important role that parental playfulness has on parent–child interaction as well as the need to examine moderation patterns separately for fathers and mothers.     

Multi-body dynamic coupling mechanism for generating throwing arm velocity during baseball pitching

The purpose of this study was to identify the detailed mechanism how the maximum throwing arm endpoint velocity is determined by the muscular torques and non-muscular interactive torques from the perspective of the dynamic coupling among the trunk, thorax and throwing and non-throwing arm segments. The pitching movements of ten male collegiate baseball pitchers were measured by a three-dimensional motion capture system. Using the induced-segmental velocity analysis (IVA) developed in this study, the maximum fingertip velocity of the throwing arm (MFV) was decomposed into each contribution of the muscular torques, passive motion-dependent torques due to gyroscopic moment, Coriolis force and centrifugal force, and other interactive torque components. The results showed that MFV (31.6 ± 1.7 m/s) was mainly attributed to two different mechanisms. The first is the passive motion-dependent effect on increasing the angular velocities of three joints (thorax rotation, elbow extension and wrist flexion). The second is the muscular torque effect of the shoulder internal rotation (IR) torque on generating IR angular velocity. In particular, the centrifugal force-induced elbow extension motion, which was the greatest contributor among individual joint contributions, was caused primarily by the angular velocity-dependent forces associated with the humerus, thorax, and trunk rotations. Our study also found that a compensatory mechanism was achieved by the negative and positive contributions of the muscular torque components. The current IVA is helpful to understand how the rapid throwing arm movement is determined by the dynamic coupling mechanism.
