Children with developmental language disorder (DLD) are at risk for social, emotional, and behavioral (SEB) maladjustment throughout development, though it is unclear if poor language proficiency per se can account for this risk as associations between language and SEB appear more variable among typical-language children. This study investigated whether the relationship between language and SEB problems is stronger at very low levels of language and considered confounders including socioeconomic status, sex, and nonverbal intelligence. These were examined using a population-based survey design, including children with a wide range of language and cognitive profiles, and assessed using the Strengths and Difficulties Questionnaire and six standardized language measures (n = 363, weighted n = 6,451). Structural equation models adjusted for prior levels of SEB revealed that the relationship of language at age 5–6 years to SEB at 7–9 years was nonlinear. Language more strongly predicted all clusters of SEB at disordered language levels relative to typical language levels, with standardized betas of −.25 versus .03 for behavioral, −.31 versus −.04 for peer, and .27 versus .03 for prosocial problems. Wald tests between these pairs of betas yielded p values from .049 to .014. Sex moderated the nonlinear association between language and emotional symptoms. These findings indicate a clinical need to support language development in order to mitigate against problems of SEB and to carefully monitor the mental health needs of children with DLD, particularly in the context of multiple, and potentially sex-specific, risks.

The ability to accurately identify and label emotions in the self and others is crucial for successful social interactions and good mental health. In the current study we tested the longitudinal relationship between early language skills and recognition of facial and vocal emotion cues in a representative UK population cohort with diverse language and cognitive skills (N D369), including a large sample of children that met criteria for Developmental Language Disorder (DLD, N D97). Language skills, but not non-verbal cognitive ability, at age 5-6 predicted emotion recognition at age 10-12. Children that met the criteria for DLDshowed a large deficit in recognition of facial and vocal emotion cues. The results highlight the importance of language in supporting identification of emotions from non-verbal cues. Impairments in emotion identification may be one mechanism by which language disorder in early childhood predisposes children to later adverse social and mental health outcomes.

Although multiple studies across the world have shown that low language ability associates with three major clusters of low socio-emotional functioning in childhood- behavioural, emotional and ADHD type, little is known about how these relationships come to develop, while even less is known among children who grow up learning two or more languages. This is of global concern, as a substantial number of individuals who speak two languages exist around the world and even form the majority in some countries such as Singapore. Moreover, both low language and low socio-emotional functioning is closely associated with multiple negative costs in later life to community and state resources. In this chapter, I first focus on the pre-school period and provide a framework for understanding the early development of language. Next, recent systematic reviews regarding the contribution of language to socio-emotional functioning are synthesised. In brief, both cross-sectional and longitudinal reviews report linkages between language and socio-emotional functioning. Such linkage can be variable, with age, level of language proficiency and type of socio-emotional functioning postulated as explanations for such variability. Finally, as Singapore is a country with a substantial number of children who grow up learning two or more languages, findings regarding the estimates and nature of the relationship between language and socio-emotional functioning in multi-lingual environments are discussed.

From a conditional adaptation vantage point, early life caregiving adversity likely enhances aspects of cognition needed to manage interpersonal threats. Yet, research examining early life care and offspring cognition predominantly relies upon experiments including affectively neutral stimuli, with findings generally interpreted as “early-life caregiving adversity is, de facto, ‘bad’ for cognitive performance.” Here, in a Southeast Asian sample, we examined observed maternal sensitivity in infancy and cognitive performance 3 years later as preschoolers took part in three tasks, each involving both a socioemotional (SE) and non-socioemotional (NSE) version: relational memory (n = 236), cognitive flexibility (n = 203), and inhibitory control (n = 255). Results indicate the relation between early life caregiving adversity and memory performance significantly differs (Wald test = 7.67, (1), P = 0.006) depending on the SE versus NSE context, with maternal sensitivity in infancy highly predictive of worse memory for SE stimuli, and amongst girls, also predictive of better memory when NSE stimuli are used. Results concerning inhibitory control, as well as cognitive flexibility in girls, also tentatively suggest the importance of considering the SE nature of stimuli when assessing relations between the caregiving environment and cognitive performance. As not all approaches to missing data yielded similar results, implications for statistical approaches are elaborated. We conclude by considering how an adaptation-to-context framework approach may aid in designing pedagogical strategies and well-being interventions that harness pre-existing cognitive strengths.

The goal of this prospective longitudinal study was to explore whether co-occurrent internalizing difficulties and aggression in early childhood convey increased risk for later mental health problems in middle childhood. Participants were mothers from the Norwegian Mother, Father and Child Cohort Study (MoBa), who provided assessments of child internalizing difficulties and aggression at ages 3 years (n = 54,644; 26,750 girls) and 5 years (n = 38,177; 18,794 girls), as measures of child depressive, anxiety, conduct-related, and oppositional defiant (OD) symptoms at age 8 years. Using latent profile analyses (LPA) of internalizing difficulties and aggression, four profiles were identified: low-symptom/normative; primarily internalizing; primarily aggressive; and co-occurrent. Among the other results, the co-occurrent group exhibited the highest levels of depressive, anxiety, and oppositional defiant symptoms at 8 years. Most children (78%) remained stable in their profile between ages 3 and 5 years. Among the transition patterns that emerged, transitions were observed both from the normative to a risk profile and vice versa. Children who remained stable within the co-occurrent profile or who transitioned from the co-occurrent profile to one of the other two risk profiles also exhibited more depressive, anxiety, and OD symptoms at 8 years of age, when compared with children who transitioned from the co-occurrent to the normative profile. The heterogeneity between early manifestation of internalizing difficulties and aggression, and specific type of later mental health symptoms not only supports a shared etiology between internalizing and externalizing difficulties but also points toward the need for person-centered monitoring in early childhood with further implications for early identification of difficulties and preventive measures.
