Autistic women often struggle with the onset of menstruation, a key transition point in the female reproductive lifespan. Presently, there is no research investigating how autistic people navigate the menopausal transition, and whether it poses additional challenges in addition to those already faced by neurotypical women. As a preliminary…

Retrospective parental reports are common in the developmental science literature, but their validity has been questioned. We investigated the consistency of retrospective maternal recall by comparing original with retrospective maternal reports in three domains (maternal cognitions, mother-reported child and mother behaviors, and observed child…

Background: Speech-sound development in preschoolers with unilateral cleft lip and palate (UCLP) as a group is delayed/disordered, and obstruents comprise the most vulnerable sound class. Aims: To evaluate the development of obstruent correctness (PCC-obs) and error types (cleft speech characteristics (CSCs) and developmental speech…

Early adolescence represents a particularly sensitive period in the life of young learners, which is accompanied by an increase in school alienation. Due to its harmful nature (Hascher and Hadjar in Educ Res 60:171-188, 2018. 10.1080/00131881.2018.1443021), school alienation may lead to unfavorable consequences such as low academic achievement…

Competition is a ubiquitous component of American culture and in many US physical education programs. In this article, five myths associated with competition are dispelled: (1) Everyone likes competition, (2) Competition is motivational, (3) Competition is fun, (4) Competition promotes physical activity, and (5) Competition prepares children for…

Infants start learning words, the building blocks of language, at least by 6 months. To do so, they must be able to extract the phonological form of words from running speech. A rich literature has investigated this process, termed word segmentation. We addressed the fundamental question of how infants of different ages segment words from their…

Anxiety is a common symptom among college counseling clients. Perhaps because of the unique developmental tasks they face, many later adolescents (ages 18-24 years) use religious coping to manage anxiety. Many counselors are uncertain about how to address religious themes in therapy, if at all. However, most clients of faith do not want counselors…

Spatial thinking is an important predictor of mathematics. However, existing data do not determine whether all spatial sub-domains are equally important for mathematics outcomes nor whether mathematics-spatial associations vary through development. This study addresses these questions by exploring the developmental relations between mathematics…

Self-regulatory abilities have been shown to be closely linked to academic success. There are a variety of measurement tools to assess self-regulated learning in pupils and students. Crucially, preschool age marks a sensible period for the maturation of self-regulated learning (SRL) and related abilities such as executive-control functions (EF).…

Part II of this two-part article continues the discussion of what Maria Montessori viewed to be the important components of her educational system. Because she developed the system over her lifetime, we prioritized later accounts when contradictory accounts were found. Whereas Part I focused on the environment, Part II examines the second and…

Optimal talent development can only occur when high ability students are willing to take opportunities for growth in a domain and are able to persist when presented with challenges that accompany performance or production at the highest levels. This paper proposes the use of Erikson's theory of psychosocial development to provide a framework…

Toddlers with an older sibling with autism spectrum disorder (ASD) and low risk (LR) toddlers were observed at 22, 28, and 34 months during two empathy probes: a crying baby and an adult who pretended to hurt her finger. Toddlers with a later ASD diagnosis showed less empathic concern and self-distress at each age on both empathy probes than LR…

The current study estimated the causal links between preschool mathematics learning and late elementary school mathematics achievement using variation in treatment assignment to an early mathematics intervention as an instrument for preschool mathematics change. Estimates indicate (n = 410) that a standard deviation of intervention-produced change…

Background: In the general population, the transition from adolescence to adulthood has been identified as a "high-risk" period for weight gain. There has been no research examining health behaviours over this transition in adults with intellectual disabilities. Methods/design: The feasibility of recruitment, retention and relevant…

Lockhart and Keil have written an interesting monograph focusing on the development of reasoning about medicine, a relatively underexplored area of research with potentially broad implications with respect to the design of more effective medical interventions. In a set of fifteen studies with well over 2200 participants they examine how children…
