Maternal psychiatric and personality diagnoses were verified with structured clinical interviews during pregnancy. Maternal concurrent level of psychiatric symptoms was assessed by self-report and infant-mother attachment quality by observation in the Strange Situation Procedure at 14 months postpartum. In the full sample, almost half of the infants were classified as disorganized. All infants of mothers with a comorbid personality disorder were classified as either insecure or disorganized. Infants of mothers with a comorbid personality disorder had a significantly higher disorganization score than infants of mothers with a psychiatric disorder only. Continuous attachment security scores did not differ significantly between groups. In the full sample, continuous infant attachment security and disorganization score were not significantly correlated with the level of maternal concurrent psychiatric symptoms. Our exploratory findings suggest a specific link between maternal psychiatric and comorbid personality disorder and attachment disorganization. Moreover, chronicity of symptoms appears more relevant for attachment behaviors than the severity of concurrent psychiatric symptoms. Maternal personality disorder may have a strong formative impact on infant attachment security and disorganization, which warrants further research to inform clinical practice, in order to reduce the risk of intergenerational transmission of maternal psychopathology.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"76 ","pages":"Article 101974"},"PeriodicalIF":2.1,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0163638324000535/pdfft?md5=2fb29358aaa0c66e7d8640c4328ef281&pid=1-s2.0-S0163638324000535-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141422941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From a dynamic systems perspective, the interaction between environment, tasks, and organismic constraints leads to the emergence of new behaviors over time. This 6-month longitudinal study aimed to verify associations between the emergence of locomotor behaviors and infants' characteristics, developmental status, parental beliefs, and practices. This observational study remotely assessed 37 full-term Brazilian infants aged 5 to 15 months, divided into two groups (G1: 5 to 11 months, n = 19; and G2: 9 to 15 months, n = 18). The motor developmental status of infants was closely associated with the emergence of behaviors (p &lt; 0.05). Infants in G2 whose parents agreed with the statement \"In typically developing infants, motor development occurs naturally and there is no need to actively stimulate it\" started to walk later than those whose parents disagreed. Infants whose parents expected them to walk around 10–11 months walked earlier compared to those expected to walk after 11 months (G2, p = 0.011). Infants in G2 with a high frequency of staying in the supine position started to walk, both with and without support, later than those with a low frequency (p &lt; 0.05). For infants in G1 with a high frequency of playing on the floor, locomotion (p = 0.041) and crawling on hands-and-knees (p = 0.007) started sooner compared to those with a low frequency. Staying in the cradle more frequently was related to a later emergence of supported walk (p = 0.046) among infants in G2. The emergence of locomotor behaviors is associated with motor developmental status, the surfaces where the infant plays, and body position. Parental beliefs and expectations influence how infants are stimulated and, consequently, the emergence of independent walking.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"76 ","pages":"Article 101965"},"PeriodicalIF":2.1,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141313431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unknown is the extent to which these effects are the result of the activation of C-Tactile afferents (CTs), the constellation of nerve fibers associated with affective touch, primarily located in the head and trunk of the body. The purpose of the present study was to compare dynamic touch (CTs activated) to static touch (CTs less activated) during a babywearing procedure among infants experiencing Neonatal Opioid Withdrawal Syndrome (NOWS). NOWS is a spectrum of clinical symptoms, including elevated heart rate (HR), associated with withdrawal from intrauterine opioid exposure. We hypothesized that stroking an infant’s head during babywearing would amplify the pleasurable effect of babywearing as measured by changes in infant HR. Twenty-nine infants in a Neonatal Intensive Care Unit (NICU) in the Southwestern USA were worn in an infant carrier starting at five days old (<em>M =</em> 5.4, SD = 2.6; 46.2 % White, 26.9 % Latinx, 11.5 % Native American) and physiological readings were conducted daily; heart rates of infants and caregivers were taken every 15-seconds for 5-minutes, <em>before</em>, <em>during</em>, and <em>after</em> babywearing (30 min per phase). Each day infants alternated (randomly) in a static touch (hands-free babywearing) or dynamic touch condition (stroking the top of the infants’ head at a velocity of 3 cm/s while babywearing). On average, infants completed 3 dynamic and 3 static babywearing sessions. Hospital and research staff participated in babywearing when a parent was not available (31.0 % of infants were exclusively worn by volunteers, 27.6 % were exclusively worn by parents). We analyzed the data using Hierarchical Linear Models due to the 3-level nested design (<em>N</em> = 29 infants, <em>N</em> = 191 readings, <em>N</em> = 11,974 heart rates). Compared to baseline (infant calm/asleep and without contact), infant’s HRs significantly declined during and after babywearing, controlling for pharmacological treatment. These effects were significantly stronger during the dynamic touch condition (reduction in HR of 11.17 bpm) compared to the static touch condition (reduction in HR of 3.74 bpm). These effects did not significantly vary by wearer (mother, father, volunteer). However, differences between the dynamic and static conditions were significantly stronger in earlier babywearing sessions, potentially indicating a learning effect. There was evidence for a calming effect among caregivers as well, particularly in the dynamic touch condition, when caregivers were engaged in active touch. Activation of CTs appears to be an important mechanism in the physiological benefits of babywearing and in the symbiotic role of caregiver-infant attachment.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"76 ","pages":"Article 101960"},"PeriodicalIF":2.1,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141184527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study identified four types of conceptual definitions for SR, each associated with different constructs or sets of constructs: executive functions, temperament, the integration of executive functions and temperament, and physiological homeostasis. These definitions were based on mainstream approaches to SR rather than being specific to the Latin American region. The study also found compatibility between the sample and some observed trends.
