Externalizing behaviors and attachment disorganization in children of different‐sex separated parents: The protective role of joint physical custody

The aim of this study was to examine the relationship between externalizing behaviors and the quality of attachment representations in preschool children, and to determine if family type and custody arrangement had a moderating effect on this relationship. The participants were 33 girls and 31 boys (n = 64) aged between three and six years (M = 4.75; SD = 0.87 years) and their mothers. Among them, 36 came from “intact” families, 13 were living mainly with their mothers and 15 were in joint physical custody. Children’s attachment representations were assessed with the Attachment Story Completion Task (Bretherton, Ridgeway & Cassidy, 1990). Mothers reported on their child’s behavior problems using the Child Behavior Checklist (Achenbach & Rescorla, 2001) and on their alliance with the father using the Parenting Alliance Inventory (Abidin & Brunner, 1995). Although children’s externalizing behaviors were found to be associated with the disorganization of their attachment representations, this relationship was significantly weaker and was non‐significant for children in joint physical custody. Thus, the results of this pilot study suggest that joint custody may protect children of separated parents from the effects of attachment disorganization on externalizing behaviors.

Parent–child interactions during traditional and interactive media settings: A pilot randomized control study

Parent–child interactions are pivotal for children's socioemotional development, yet might suffer with increased attention to screen media, as research has suggested. In response, we hypothesized that parent–child play on a tablet computer, as representative of interactive media, would generate higher‐quality parent–child interactions than toy play or watching TV . We examined the emotional availability of mothers and their 2‐year‐old child during the previous three contexts using a randomized crossover design (n = 22) in a laboratory room. Among other results, mothers were more sensitive and structuring during joint gaming on a tablet than when engaged in toy play or watching TV . In addition, mothers were more hostile toward their children during play with traditional toys than during joint tablet gaming and television co‐viewing. Such findings provide new insights into the impact of new media on parent–child interactions, chiefly by demonstrating that interactive media devices such as tablets can afford growth‐enhancing parent–child interactions.     

Responsabilité médicale et « option »

Medical liability is, in civil law, the suit of a breach of the contract. But, sometimes, it depends of the law of torts (that is the reference in common law). The patient cannot choose between the two systems. If the damage proceeds of a contractual negligence, there is only a conctractual liability. Two projects of law ((ministry of justice) are in another way; they will offer the option. Is it a good solution for the patient?     

The influence of the human TMJ eminence inclination on predicted masticatory muscle forces

Aim of this paper was to investigate the change in masticatory muscle forces and temporomandibular joint (TMJ) reaction forces simulated by inverse dynamics when the steepness of the anterior fossa slope was varied. We used the model by de Zee et al. (2007) created in AnyBody™. The model was equipped with 24 musculotendon actuators. Mandibular movement was governed by the trajectory of the incisal point. The TMJ was modelled as a planar constraint canted 5° medially and the caudal inclination relative to the occlusal plane was varied from 10° to 70°. Our models showed that for the two simulated movements (empty chewing and unilateral clenching) the joint reaction forces were smallest for the eminence inclination of 30° and 40° and highest for 70°. The muscle forces were relatively insensitive to change of the eminence inclination for the angles between 20° and 50°. This did not hold for the pterygoid muscle, for which the muscle forces increased continually with increasing fossa inclination. For empty chewing the muscle force reached smaller values than for clenching. During clenching, the muscle forces changed by up to 200 N.     

AN EASTERN ORTHODOX CRITIQUE OF THE SCIENCE–THEOLOGY DIALOGUE

On the basis of both philosophical arguments and the theological perspectives of Eastern Orthodox Christianity, a critique of two beliefs that are common within the mainstream science–theology dialogue is outlined. These relate to critical realism in understanding language usage and to naturalistic perspectives in relation to divine action. While the naturalistic perspectives on the history of the cosmos that are predominant within the dialogue are seen as generally acceptable from an Orthodox perspective, it is argued that they require theological expansion. This expansion suggests an understanding other than the “causal joint” model commonly adopted in relation to “special” divine action. This alternative model renders the distinction between “special” and “general” divine action redundant, and is based on what has been called a “teleological‐Christological” understanding of the cosmos, rooted in the fourth gospel's notion of the divine Logos. The relevance of this critique to scholars outside of the Orthodox community is urged.     

Covert verbal mediation in arbitrary matching to sample

Covert verbal mediation was examined in an arbitrary matching‐to‐sample (MTS) preparation with a high‐verbal group (college students) and a low‐verbal group (adults with intellectual disabilities). Arbitrary relations were established between nonsense words, visual symbols, objects, and hand signs. Task difficulty was balanced for the groups based on errors during acquisition. All participants experienced a hand sign condition, and three MTS conditions each with a unique configuration of the comparison array: fixed location, random location, and all symbols the same. The same symbol condition was designed to impede a participant's ability to label individual symbols. The results showed that disrupting labeling adversely affected MTS performance for high‐verbal participants, but not for low‐verbal participants. The data suggest that high‐verbal participants depended on mediating verbal behavior and joint control to assist them in finding the correct comparison stimulus. Low‐verbal participants could not benefit from verbal mediating variables and likely relied on unmediated contingencies, or some form of nonverbal mediation. For the high‐verbal group, 19 different putative emergent relations were identified as occurring at various stages of acquisition between the sample stimulus and the selection response. These emergent relations likely provided supplementary sources of stimulus control that participated in evoking MTS selection behavior.

Triadic interactions support infants’ emerging understanding of intentional actions

Infants’ understanding of the intentional nature of human action develops gradually across the first year of life. A key question is what mechanisms drive changes in this foundational social‐cognitive ability. The current studies explored the hypothesis that triadic interactions in which infants coordinate attention between a social partner and an object of mutual interest promote infants’ developing understanding of others as intentional agents. Infants’ spontaneous tendency to participate in triadic engagement was assessed in a semi‐structured play session with a researcher. Intentional action understanding was assessed by evaluating infants’ ability to visually predict the goal of an intentional reaching action. Study 1 (N = 88) revealed that 8‐ to 9‐month‐olds who displayed more bouts of triadic engagement showed better concurrent reasoning about the goal of an intentional reaching action. Study 2 (N = 114) confirmed these findings using a longitudinal design and demonstrated that infants who displayed more bouts of triadic engagement at 6–7 months were better at prospectively reasoning about the goal of an intentional reaching action 3 months later. Cross‐lagged path analyses revealed that intentional action understanding at 6–7 months did not predict later triadic engagement, suggesting that early triadic engagement supports later intentional action processing and not the other way around. Finally, evidence from both studies revealed the unique contribution of triadic over dyadic forms of engagement. These results highlight the importance of social interaction as a developmental mechanism and suggest that infants enrich their understanding of intentionality through triadic interactions with social partners.
