Not all in-service general music teachers received instruction in vocal pedagogy for young voices. However, teaching children how to sing is highly complex. By understanding adult vocal registers and children's vocal development, as well as using effective vocal modeling and varied feedback, music teachers may create a learning experience that can…

In 1951, when Maria Montessori described the pattern of human development as the Constructive Rhythm of Life, marking each of four chapters or planes of development with an inverted triangle, she colored the first and third planes red to represent their intensity (Grazzini, 1996). These two red triangles are referred to as creative periods and…

A meaningful curriculum is one that is individualized, inclusive of the individual's unique needs and interests, and focused on building independence in current and future environments. A meaningful curriculum addresses an individual's needs and prioritizes instructional programs based on what is, potentially, most important to their lives and not…

Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of…

Trajectories of cognitive and neural development suggest that, despite early emergence, the ability to extract environmental patterns changes across childhood. Here, 5- to 9-year-olds and adults (N = 211, 110 females, in a large Canadian city) completed a memory test assessing what they remembered after watching a stream of shape triplets: the…

The present study used a novel, well-controlled paradigm to investigate the development of cool, hot-positive, and hot-negative inhibitory control in a sample of children (6- to 11-year-old; N = 38, 21 females), adolescents (12- to 18-year-old; N = 38, 24 females), and adults (19- to 38-year-old; N = 38, 28 females; sample location: United…

This study evaluates the dimensions of fractional-size violin bows in relation to the anthropometric and grip-strength measurements of children and adults. In string education, various methods and devices have been put forward to measure children for the correct violin size, but there is a lack of research regarding the proper bow size. Results…

Objective: Adverse childhood experiences (ACEs), which refer to childhood traumatic events, have been identified as risk factors for tobacco use in adulthood. However, studies are limited on the effect of sex on the association of ACEs with e-cigarettes and dual use of e-cigarettes and cigarettes. This study explored sex differences in the…

Autobiographical remembering develops in childhood. A late-developing cognitive tool is the cultural life script. The present study aimed at exploring the beginnings of its acquisition and at replicating its acquisition in early adolescence in a Southern-European culture. Study 1 established the Portuguese normative adult cultural life script,…

Two preregistered experiments (N = 218) investigated children's developing ability to respond reasonably to disagreement. U.S. children aged 4-9, and adults (50% female, mostly white) formed an initial belief, and were confronted with the belief of a disagreeing other, whose evidence was weaker, stronger than, or equal to participants' evidence.…

When "Sesame Street" launched in 1969, it was the first show to attempt to teach young children school-readiness skills with catchy songs and playful Muppets. Not only did it revolutionize the children's media landscape, the program sparked a love of learning among generations of children all over the world. For "Revisiting the…

Maurice Sendak's picture book Where the "Wild Things Are" was investigated as a means of emotion recognition in preschool children. Sixty-six children and 60 adults participated in two tasks. The first was a book task, requiring identification of emotions in three target pictures, in three conditions. The visual condition presented the…

What do we know about immersive media--virtual, augmented, mixed, and cross realities (VR, AR, MR, and XR)--and young children? So far, designers, developers, and media producers have been focusing on creating hardware, software, and content for and conducting studies with adolescents and adults--but children find these technologies incredibly…

Testing of previously studied information potentiates subsequent learning of new information, a phenomenon referred to as the "forward testing effect" (FTE). The current study aimed to investigate the developmental trajectory of the FTE and whether the reset-of-encoding process contributes to the FTE. Younger children, older children,…

Solitude occurs from childhood to old age. In this special issue introduction, we offer a lifespan perspective on matters of solitude with the aim to point to pertinent issues in the field. We propose that solitude serves important functions that may vary across different times in life and that solitude needs to be considered in the context in…
