Development is the complex process through which a single-celled embryo transforms into a multicellular organism. Developmental processes are guided by information encoded in an organism's DNA, and geneticists are trying to understand how this information leads to a fully formed organism. This video reviews seminal research in the field of developmental biology, including the identification of specific genes that control various embryonic processes. An introduction to the major questions asked...

Orthogonal trajectories describe the geometric relationship between two families of curves that intersect each other at right angles. One illustrative case involves a family of parabolas that open sideways along the x-axis. These curves share a common shape but differ by a scaling parameter, resulting in a set of curves that all pass through the origin and widen at different rates.Determining Orthogonal TrajectoriesTo identify the orthogonal trajectories for these parabolas, the first step...

How neuronal networks are established in the embryonic brain is a fundamental question in developmental neurobiology. Here we combined an electroporation technique with novel genetic tools, such as Cre/Lox–plasmids and PiggyBac-mediated DNA transposition system in the avian hindbrain to label dorsal interneurons and track their axonal projections and synaptic targets at various developmental stages.

Developmental neuroscience is a field that explores how the nervous system is formed, from early embryonic stages through adulthood. Although it is known that neural progenitor cells follow predictable stages of proliferation, differentiation, migration, and maturation, the mechanisms controlling the progression through each stage are incompletely understood. Studying development is not only important for understanding how complex structures are assembled, but also for characterizing and...
FAQs
Developmental change reflects the interaction of multiple influences rather than a single cause. Biological maturation may alter capacities, while learning, relationships, and environmental conditions shape how those capacities are expressed. Their effects can reinforce or offset one another over time, helping explain why individuals with similar starting points may show different psychological outcomes.
Two individuals may reach a similar outcome through different developmental routes. One may change earlier, another more gradually, and a third may show improvement followed by difficulty. Examining timing, rate, and direction therefore distinguishes temporary variation from sustained patterns and prevents researchers from treating one developmental schedule as universally typical.
Repeated observations can show whether well-being, behavior, or psychological abilities remain stable, improve, or become more difficult over time. Patterns associated with resilience may indicate adaptation despite challenging conditions, whereas persistent or worsening patterns may signal difficulty. This perspective connects outcomes with changing biological, relational, learning, and environmental influences.
Researchers first identify a psychological outcome, such as an ability, behavior, or aspect of well-being, and then observe it across developmental periods. They may follow the same individuals or examine groups over time, compare patterns of change and stability, and interpret differences in relation to maturation, learning, relationships, and environmental conditions.
This approach can identify typical pathways and variation in how development unfolds. It can show when changes occur, how rapidly outcomes shift, and whether patterns differ across individuals or groups. Such information helps psychologists distinguish broad developmental trends from individual differences and examine how contextual conditions relate to psychological growth or difficulty.
Psychologists use trajectory-based evidence to study cognitive, emotional, and social growth from one developmental period to another. Findings can support assessment by clarifying patterns of change, guide prevention by identifying factors linked to difficulty, and inform interventions designed to address needs or strengthen well-being as circumstances and developmental conditions change.
