Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

When making moral judgments of past actions, adults often think counterfactually about what could have been done differently. Considerable evidence suggests that counterfactual thinking emerges around age 6, but it remains unknown how this development influences children's moral judgments. Across two studies, Australian children aged 4-9 (N = 236,…

The current study examined financial stress, career-related optimism, and psychological distress from the age of 19 (2013; n = 5,787), until the age of 25 (2019; n = 2,933) using the Longitudinal Surveys of Australia Youth (2009 cohort). Longitudinal mediation using latent growth curve modeling observed trajectories of change across young…

Self-efficacy has been associated with benefits to everyday life such as resilience to stress and adversity, healthy behaviours, improved performance, and academic achievement. Research into self-efficacy development is scarce in early childhood, yet self-efficacy is associated with numerous skills and competencies taught in the early years of…

Piaget's theory of stage structure is synonymous with discussions involving cognitive development. As with any theoretical model, researchers inevitably and rightly seek to affirm and/or contest the elements of the model presented. In this comparative study, students' performance across three hands-on engineering tasks for two distinct student…

Infant-directed speech (IDS) is characterized by a range of register-typical characteristics. Many of those can be objectively measured, such as acoustic-prosodic and structural-linguistic modifications. Perceived vocal affect, however, is a socio-emotional IDS characteristic and is subjectively assessed. Vocal affect goes beyond acoustic-prosodic…

Two case studies of Australian primary school students tracked changes in their data interpretation and representation over three years. Students were engaged in predictive reasoning tasks based on their interpretation of a data table showing temperature change over time. Students' explanations and graphical representations were collected at the…

The aim of this study was to establish the content of a teacher-oriented movement assessment tool (MAT) for children aged 4-7 years. A three-round Delphi poll with an international panel of forty-six academics and practitioners was conducted. Consensus was reached on a selection and number of fundamental movement skills to be assessed with four…

School Age Care is a setting that is little researched and the research that has been conducted has not often sought the perspectives of older children. This article describes a participatory and ethnographic research project that sought a deeper insight into older children's experiences of an Australian School Age Care setting, seeking their…

The question of when moral identity first develops in childhood deserves more considered investigation. In this article, we examine the claim that moral identity first emerges in middle-childhood (8-12 years). An approach is taken here whereby a tendency to attribute moral shame under conditions entailing moral identity failure is considered as…

Aim: To investigate developmental trajectories in early childhood and predictors of class assignment. Methods: Data were available for Gen2 infants at 12 (n = 2275), 24 (n = 1845) and 36 (n = 2110) months of age in the Raine Study. Latent growth class analysis was used to identify developmental trajectories based on the Ages and Stages…

Children hold strong ingroup biases from a young age, liking ingroup over outgroup members and preferring them as social learning models. Simultaneously, children are also highly prosocial--both in their own helping behaviors and their avoidance of those who behave antisocially. This study explores how children of 2 age groups (4-5 and 7-8 years)…

Purpose: Infant vocal durations have been studied from a variety of perspectives, including medical, social, and linguistic. The resultant developmental profile across the first 6 months of life, however, is still far from clear. The purpose of this study was to evaluate the durational properties of infant vocalizations from the unique perspective…

Our identity develops with age, and many impacting factors will determine whether it is healthy or unhealthy. A particularly fragile phase of identity development occurs during adolescence when level of motor competence may be influential, yet is rarely considered. Purpose: The purpose of this study was to examine male and female adolescent's…

Purpose: The current study aimed to compare traditional logistic regression models with machine learning algorithms to investigate the predictive ability of (a) communication performance at 3 years old on language outcomes at 10 years old and (b) broader developmental skills (motor, social, and adaptive) at 3 years old on language outcomes at 10…
