DISCRETE MOVEMENT TASK
A movement task with a start and an end. Compare continuous movement task. DISCRETE MOVEMENT TASK: “A discrete movement task has a defined beginning and end.”
KINESTHESIS
Introduction to Kinesthesis Kinesthesis, often referred to as kinesthesia, is the sensory experience that provides the central nervous system (CNS) with continuous, non-visual information about the body’s movement, effort, and location in space. It is a critical component of the somatosensory system, working alongside the vestibular system (balance) and vision to ensure effective motor control. […]
BIPEDAL LOCOMOTION
Defining Bipedal Locomotion and its Biological Context Bipedal locomotion is fundamentally defined as the physical and mechanical ability to move the body forward through space using only two limbs, specifically the two rear limbs, commonly referred to as the legs in terrestrial vertebrates. This mode of advancement is characterized by a carefully orchestrated sequence of […]
EDUCATIONAL SPORT PSYCHOLOGIST
The Educational Sport Psychologist: Definition and Scope The role of the Educational Sport Psychologist is fundamentally rooted in the application of psychological principles to enhance human movement, athletic performance, and overall well-being within the domain of sport and exercise. This specialization focuses primarily on teaching athletes, coaches, and teams the mental skills necessary for optimal […]
STABILIMETER
Introduction and Core Definition of the Stabilimeter The stabilimeter is an indispensable psychophysiological instrument specifically engineered to quantify and analyze postural stability in humans. Its primary function is the precise measurement of spontaneous body movements, commonly referred to as body sway, which occurs when an individual maintains an upright stance. This measurement is crucial because […]
MOVEMENT CHAINING
Movement Chaining in Psychology and Neuroscience Core Definition of Movement Chaining Movement chaining is a foundational concept in the study of motor control, positing that complex, sequential motor actions are executed through a series of discrete, linked steps, where the successful completion of one step serves as the essential stimulus or cue for the initiation […]
MOTOR COORDINATION
Motor Coordination: Definition, Mechanisms, and Significance The Core Definition of Motor Coordination Motor coordination is fundamentally defined as the cooperative and synchronized action between both involuntary and voluntary motions necessary to complete complex activities with precision, speed, and efficiency. This process involves the seamless integration of sensory information—such as vision, touch, and proprioception—with the central […]
BIOMECHANICS
Biomechanics: The Mechanics of the Human Musculoskeletal System The Core Definition of Biomechanics Biomechanics is a highly specialized scientific discipline dedicated to the study of the mechanics of forces acting upon a biological body, particularly the musculoskeletal system of humans and animals. At its core, it applies the fundamental principles of classical mechanics, such as […]
MOTOR DOMINANCE
Motor Dominance The Core Definition of Motor Dominance Motor dominance, at its core, refers to the consistent and observable preference an individual demonstrates for utilizing one side of their body—specifically one limb—over the other when executing complex or unilateral motor tasks. This preference is far more profound than mere habit; it represents a fundamental functional […]
