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...

Plastic sections maintain true tissue morphology in thin sections of tissue that can be immunostained with fluorescent secondary antibodies, making this method more useful than paraffin-embedded or frozen sections for many types of tissue. The method for staining, plastic embedding, and sectioning is demonstrated in this video.

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...

Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Plasticizers

Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas. Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Sensitive periods are stages when environmental influences can have especially strong effects on development. During these windows, caregiving, stress, nutrition, and learning may alter neural connectivity, synaptic organization, and brain circuitry. In psychology, this helps explain why similar experiences can produce different outcomes depending on when they occur, while also highlighting opportunities for experiences that support healthy cognitive and behavioral growth.
Experiences can affect development through changes in gene expression, synaptic organization, and brain circuitry. These processes provide pathways through which environmental conditions and internal signals become linked to later cognitive abilities, behavior, and emotional functioning. Their influence helps account for developmental flexibility, but it also means that adverse conditions may contribute to increased vulnerability during psychological growth.
Developmental plasticity does not produce identical responses to a shared environment. Outcomes reflect the interaction of environmental conditions, experiences, and internal signals, which can influence neural connectivity and behavior in different ways. This framework helps psychologists study individual differences, including why some people show adaptive growth while others exposed to adverse conditions develop emotional, cognitive, or behavioral difficulties.
Psychologists consider these factors as distinct experiences that may shape development through related changes in neural connectivity, gene expression, synaptic organization, and brain circuitry. Examining them helps connect environmental conditions with cognitive abilities, behavior, and emotional outcomes. This approach also supports identifying protective experiences and recognizing circumstances that may increase developmental vulnerability.
Research on developmental plasticity can guide interventions by identifying experiences that promote healthy development and by clarifying how adverse environments relate to later difficulties. Protective caregiving, supportive learning, and other beneficial conditions can therefore become important targets for psychological practice. The goal is to use knowledge of developmental flexibility to support emotional, cognitive, and behavioral functioning.
Developmental plasticity is relevant across the lifespan because psychological growth and adaptation remain connected to environmental conditions, experiences, and internal signals. Studying these relationships helps explain changing cognitive abilities, behavior, and emotional functioning beyond a single developmental stage. It also allows psychology to consider when supportive experiences may strengthen adaptation or when adverse conditions may increase vulnerability.
