Dexterity Game
Fine motor skill (or dexterity) is the coordination of small muscles in movement with the eyes, hands and fingers. The complex levels of manual dexterity that humans exhibit can be related to the nervous system. Fine motor skills aid in the growth of intelligence and develop continuously throughout the stages of human development. Types of motor skills Motor skills are movements and actions of the bone structures. Typically, they are categorised into two groups: gross motor skills and fine motor skills. Gross motor skills are involved in movement and coordination of the arms, legs, and other large body parts. They involve actions such as running, crawling and swimming. Fine motor skills are involved in smaller movements that occur in the wrists, hands, fingers, feet and toes. Specifically, single joint movements are fine motor movements and require fine motor skills. They involve smaller actions such as picking up objects between the thumb and finger, writing carefully, and blink ...

Nervous System
In biology, the nervous system is the complex system, highly complex part of an animal that coordinates its behavior, actions and sense, sensory information by transmitting action potential, signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. Nervous tissue first arose in Ediacara biota, wormlike organisms about 550 to 600 million years ago. In Vertebrate, vertebrates, it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers, or axons, that connect the CNS to every other part of the body. Nerves that transmit signals from the brain are called motor nerves (efferent), while those nerves that transmit information from the body to the CNS are called sensory nerves (aff ...

Developmental Disability
Developmental disability is a diverse group of chronic conditions, comprising mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living".Center for Disease Control and Prevention. (2013)Developmental disabilities.Retrieved October 18, 2013 Developmental disabilities can be detected early on and persist throughout an individual's lifespan. Developmental disability that affects all areas of a child's development is sometimes referred to as global developmental delay. The most common developmental disabilities are: * Motor disorders, and learning difficulties such as dyslexia, Tourette's syndrome, dyspraxia, dysgraphia, dyscalculia, and nonverbal learning disorder. * Autism spectrum disorder (ASD, formerly the PDD umbrella covering Asperger syndrome and classic autism) causes difficulties in s ...

Aptitude
An aptitude is a component of a competence to do a certain kind of work at a certain level. Outstanding aptitude can be considered "talent", or "skill". Aptitude is inborn potential to perform certain kinds of activities, whether physical or mental, and whether developed or undeveloped. Aptitude is often contrasted with skills and abilities, which are developed through learning. The mass term ability refers to components of competence acquired through a combination of both aptitude and skills. According to Gladwell (2008) and Colvin (2008), it is often difficult to set apart the influence of talent from the influence of hard training in the case of outstanding performances. Howe, Davidson, and Sloboda argue that talents are acquired rather than innate. Talented individuals generally show high levels of competence immediately in only a narrow range of activities, often comprising only a single direction or genre. Intelligence and aptitude Aptitude and IQ are different ...

Sleight Of Hand
Sleight of hand (also known as prestidigitation or ''legerdemain'' () comprises fine motor skills used by performing artists in different art forms to entertain or manipulate. It is closely associated with close-up magic, card magic, card flourishing and stealing. Because of its heavy use and practice by magicians, sleight of hand is often confused as a branch of magic; however, it is a separate genre of entertainment and many artists practice sleight of hand as an independent skill. Sleight of hand pioneers with worldwide acclaim include Dan and Dave, Ricky Jay, Derek DelGaudio, David Copperfield, Yann Frisch, Norbert Ferré, Dai Vernon, Jerry Sadowitz, Cardini, Tony Slydini, Helder Guimarães and Tom Mullica. Etymology and history The word ''sleight'', meaning "the use of dexterity or cunning, especially so as to deceive", comes from the Old Norse. The phrase ''sleight of hand'' means "quick fingers" or " trickster fingers". Common synonyms of Latin and Frenc ...

Depth Perception
Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions. Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues. Binocular cues are based on the receipt of sensory information in three dimensions from both eyes and monocular cues can be observed with just one eye. Binocular cues include retinal disparity, which exploits parallax and vergence. Stereopsis is made possible with binocular vision. Monocular cues include relative size (distant objects subtend smaller visual angles than near objects), texture gradient, occlusion, linear perspective, contrast differences, a ...

Spatial Awareness
Spatial contextual awareness consociates contextual information such as an individual's or sensor's location, activity, the time of day, and proximity to other people or objects and devices.Chen, Guanling, and David Kotz. 2000. A Survey of Context-Aware Mobile Computing Research. Dartmouth Computer Science Technical Report TR2000-381. It is also defined as the relationship between and synthesis of information garnered from the spatial environment, a cognitive agent, and a cartographic map. The spatial environment is the physical space in which the orientation or wayfinding task is to be conducted; the cognitive agent is the person or entity charged with completing a task; and the map is the representation of the environment which is used as a tool to complete the task.Freksa, Christian, Alexander Klippel, and Stephan Winter. 2005. A Cognitive Perspective on Spatial Context. Dagstuhl Seminar Proceedings 05491. An incomplete view of spatial contextual awareness would render it as s ...

Box And Blocks Test
In Physical medicine and rehabilitation, rehabilitation medicine, the Box and Block Test is a functional test used in upper limb rehabilitation. While often referred to as the Box and Blocks test, the original article refers to the test as the Box and Block Test. The test is used to measure the gross manual dexterity of a patient or a person using an upper limb Prosthesis, prosthetic device. The test consists of a box with a partition in the middle. The box is placed on the table with blocks placed on one side of the partition. The test subject is given 60 seconds to move as many blocks as possible from one side of the partition to the other, using only the tested hand (the subject's own hand or a prosthetic device operated by the subject). The number of displaced blocks is a measure of the gross manual dexterity, where a higher number of displaced blocks indicates better fine motor skill. The outcome can be compared to reference values from healthy test subjects or from tests perfo ...

Purdue Pegboard Test
The Purdue Pegboard Test is a psychomotor test of manual dexterity and bimanual coordination. The test involves two different abilities: gross movements of arms, hands, and fingers, and fine motor extremity, also called "fingerprint" dexterity. Poor Pegboard performance is a sign of deficits in complex, visually guided, or coordinated movements that are likely mediated by circuits involving the basal ganglia. History Joseph Tiffin, an Industrial Psychologist at Purdue University, designed the test in 1948. It was originally intended for assessing the dexterity of assembly line workers. Method and interpretation The pegboard consists of a board with two parallel rows with 25 holes into which cylindrical metal pegs are placed by the examinee. The test involves a total of four trials. To begin, there is a brief practice. The subsets for preferred, non-preferred, and both hands require the patient to place the pins in the holes as quickly as possible, with the score being the number ...

Force Matching
Force matching is a research method consisting of test subjects attempting to produce a set forces that are equal to a set of more reliable reference forces. Types Biomechanical A subject’s maximum voluntary contraction (MVC) is recorded and used to normalize both reference forces and results between subjects. During the test subjects are assisted in producing a reference force using various types of feedback (static weight or visual display of force generated). This is followed by an attempt of the subject to generate the reference force without assistance. The duration for both reference and matching tasks is usually four seconds. Results are taken as a mean value of force generated over a time interval set by the researcher. Time intervals are generally one second long and near the end of the attempt. Reference forces are typically set as a percentage of a subject’s MVC while error is typically reported as a percentage of a subject’s MVC. Atomic It is one of the effect ...

Joint
A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole.Saladin, Ken. Anatomy & Physiology. 7th ed. McGraw-Hill Connect. Webp.274/ref> They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other joints such as suture (joint), sutures between the bones of the skull permit very little movement (only during birth) in order to protect the brain and the sense organs. The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis. Joints are classified both structurally and functionally. Joints play a vital role in the human body, contributing to movement, sta ...

Skeletal Muscle
Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the others being cardiac muscle and smooth muscle. They are part of the somatic nervous system, voluntary muscular system and typically are attached by tendons to bones of a skeleton. The skeletal muscle cells are much longer than in the other types of muscle tissue, and are also known as ''muscle fibers''. The tissue of a skeletal muscle is striated muscle tissue, striated – having a striped appearance due to the arrangement of the sarcomeres. A skeletal muscle contains multiple muscle fascicle, fascicles – bundles of muscle fibers. Each individual fiber and each muscle is surrounded by a type of connective tissue layer of fascia. Muscle fibers are formed from the cell fusion, fusion of developmental myoblasts in a process known as myogenesis resulting in long multinucleated cells. In these cells, the cell nucleus, nuclei, termed ''myonuclei'', are located along the inside ...
