Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Attention refers to the limited human ability to select some information for processing at the expense of other stimuli in the environment. Attention operates in all sensory modalities: vision, hearing, touch, even taste and smell. It is most often studied in the visual domain though. A common way to study visual attention is with a spatial cueing paradigm. This paradigm allows researchers to measure the consequences of focusing...

Spatial learning and memory are neurological functions that allow us to remember important details associated with our environment. Scientists test this phenomenon in rodents using different types of mazes like Morris water maze, Radial water maze, and Barnes maze. By investigating spatial memory in rodents, neurobehavioral scientists can gain valuable understanding of how these processes are altered following brain damage in humans. Here, the neurobiology behind spatial memory is briefly...

This lab will begin by studying motion in 1 dimension, under constant acceleration, by launching a projectile directly upward and measuring the maximum height reached. This lab will verify that the maximum height reached is consistent with the kinematic...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University One thing becomes very salient after basic exposure to the science of visual perception and sensation: what people see is a creation of the brain. As a result people may fail to see things, see things that are not there, or see things in a distorted way. To distinguish between physical reality and what people perceive, scientists use the term awareness to refer to what people perceive. To study awareness, vision scientists often...

A coordinate system assigns numerical positions to points, while geometric transformations describe how those positions change through translation, rotation, or both. This combination allows a model to represent an object's location and orientation consistently as it moves through three-dimensional space. It is especially important when analyzing changing viewpoints, connected components, or coordinated movement.
Vectors encode directional quantities such as position, velocity, and acceleration, rather than only their magnitudes. Time-dependent functions then show how those quantities evolve, allowing the model to distinguish where an object is, how quickly it moves, and how its motion changes. Together, they provide the mathematical structure needed to analyze trajectories and predict later states.
Differential equations connect changing motion to forces or constraints acting on a system. Instead of describing position independently at each moment, they express relationships among position, velocity, acceleration, and the conditions governing movement. This makes them useful for modeling physically restricted motion and for examining how specified forces or constraints influence a three-dimensional trajectory over time.
A typical workflow begins by selecting coordinate systems and representing position and orientation with geometric quantities. The model then assigns time-dependent functions for motion and introduces relationships involving velocity, acceleration, forces, or constraints when needed. After formulation, the resulting relationships can support trajectory analysis, collision examination, simulation, or control-system design.
Applications include robotics, computer graphics, aerospace engineering, and physics. In each setting, the model can examine different aspects of three-dimensional behavior, such as a trajectory, a possible collision, or the coordinated movement of multiple elements. Its quantitative description also supports prediction and simulation, helping users evaluate motion before interpreting or controlling the physical system.
By expressing location, orientation, velocity, and acceleration as quantitative relationships, a model gives a control system a structured description of the motion it must produce or interpret. Constraints can represent required relationships among moving elements, while time-dependent equations describe their evolution. This supports analysis of coordinated movement and helps connect predicted behavior with control-system design.
