Proprioception refers to the unconscious awareness and perception of joint and body movement, as well as the position of the body in space (Sherrington, 1906; as cited in Fisher et al., 1991:84). It is the “the sensory information caused by the contraction and stretching of muscles and by the bending, straightening, pulling and compression of the joints between bones” (Ayres, 2005:41). The muscles and joints constantly send information to the brain about the position of the body in space. However, most proprioceptive input does not reach consciousness except when deliberately focusing awareness on it (Ayres, 1974:41). In previous literature, a differentiation was made between kinesthesia (conscious joint proprioception) and unconscious proprioception. However researchers have begun to use these terms synonymously (Fisher et al., 1991:84).
Proprioception is related more specifically to the spatial orientation of the body and body parts in space, rate and timing of movement, the force exerted by the muscle, and the speed and intensity with which a muscle is being stretched. It plays an important role, with the tactile and vestibular system, in developing knowledge of ones own body and its movements in order to motor plan actions (Fisher et al., 1991:84). It provides the motor system with a clear map of the external environment and of the body (Matthews, 1988; as cited in Fisher et al., 1991:84) so that, during movement, the brain can plan the next movement correctly and contract the right muscle at the right time (Ayres, 2005:41).
It is important to note that active movement (internally generated) provides specific resistance to the muscles and maximal proprioceptive input, whereas passive movement (externally generated) provide...

... of these two sensory systems (Fisher et al., 1991:109). Ayres (1989; as cited in Fisher et al., 1991:109) referred to the combination of tactile and proprioceptive input as somatosensory processing. These two systems are believed to play a primary role in early development, and serve as foundations for later social, emotional and academic learning (Fisher et al., 1991:109).
Sensory integration theory provides an understanding of the relationship between the central processing of tactile inputs and behaviour. It offers explanations for why some individuals respond negatively to certain types of tactile stimuli. It also helps to understand the relationship between problems of tactile discrimination such as haptic, perception and motor planning (Fisher et al., 1991:108). Tactile stimulation and exploration through touch is essential for development (Ayres, 2005:40)
This report will explore the structure and function of skeletal muscle within the human body. There are three muscle classifications: smooth (looks smooth), cardiac (looks striated) and skeletal (looks striated). Smooth muscle is found within blood vessels, the gut and the intestines; it assists the movement of substances by contracting and relaxing, this is an involuntary effort. The heart is composed of cardiac muscle, which contracts rhythmically nonstop for the entire duration of a person’s life and again is an involuntary movement of the body. The main focus of this report is on skeletal muscle and the movement produced which is inflicted by conscious thought unless there is a potentially harmful stimulus and then reaction is due to reflex, as the body naturally wants to protect itself. Skeletal muscle is found attached to bones and when they contract and relax they produce movement, there is a specific process that the muscle fibers go through to allow this to occur.
The first is electrotactile simulation(3). It uses localized electric currents to stimulate targeted nerves using surface electrodes. This method uses no mechanical parts making it light-weight, energy conserving and less noisy in comparison to other non-invasive tactile stimulation methods. The main disadvantage of electrotactile simulation is reported burning sensations from test subjects. The second type of non-invasive tactile stimulation is vibrotactile stimulation (2), which uses mechanical vibrations on the surface of the skin to convey tactile information using varied vibrations frequency, amplitude and duration. It is best-suited for myoelectric protsthetics as it does not interfere with electric signals. Conversely, it may not be suited for older users as their sensitivity to vibrations might be diminished. The final method for non-invasive tactile stimulation is mechanotactile stimulation, which provides the user with pressure or position feedback. It provides the most natural force sensation out of all of the types of non-invasive tactile stimulation but this method also involves the largest and most energy consuming equipment, making it highly impractical to
The purpose of this assignment is to answer the three posed questions in regards to my Virtual Child, who I will refer to as Kieran throughout my assignment. I will be describing changes in his exploratory and problem solving behaviors as well as analyzing his temperament. I will also summarize his developmental assessment at nineteen months old that may differ from my perception of what was assessed through his developmental examiner. Kieran was at the age of eight months when I first used the object permanence test developed by Jean Piaget, in the aspect of sensorimotor development in both stage 3 and 4 of the Six Substages of Sensorimotor Development (Table 6-2, pg 154). At stage 3, infants begin to show greater interest in their world with objects becoming incorporated into what is called the secondary circular reaction where they start to learn about the actions associated with objects.
...ter screen an arm that was placed onto his stump. When Ture Johanson saw his arm on the computer screen, he was able to control his own movements using his own neural command. In this particular study, Johanson was asked to perform numerous movements with his phantom hands such as driving a racecar. By driving a racecar, Catalan found that the subject moved muscles at the end of his existing arm to show the intent of moving his missing hand. From this study, subjects who had been experiencing PLP for several years had longer periods without pain and had shorter periods of intense pain. In addition, the phantom hand was relaxed from a tight fist to a half-open position. This study is different from others because the control signals are retrieved from the arm stump, and thus the affected arm is in charge. Moreover, it uses the signals from the damaged limbs itself.
Off-line cognition is body-based. Even when we are separated from the environment, the activity of the mind is grounded in mechanisms that evolved for interaction with the environment- that is, mechanisms of sensory processing and motor control. This is shown with infants or toddlers best. Children utilize skills and abilities they were born with, such as sucking, grasping, and listening, to learn more about the environment. The skills are broken down into five main categories that combine sensory with motor skills, sensorimotor functions.

Let’s say that there is a mechanical sense. If someone touched your hand, your somatosensory system will detect various stimuli by your skin’s sensory receptors. The sensory information is then conveyed to the central nervous system by afferent neurons. The neuron’s dendrites will pass that information to the cell body, and on to its axon. From there it is passed onto the spinal cord or the brainstem. The neuron's ascending axons will cross to the opposite side either in the spinal cord or in the brainstem. The axons then terminates in the thalamus, and on into the Brodmann Area of the parietal lobe of the brain to process.
Piaget’s theory suggests that, at eight weeks of age, a child is in a sensorimotor stage. This means their sensory and motor skills are kicking in and the child begins to suck, grasp, look around and reach. Dayc...
Athletes must accomplish amazing feats of balance and coordination of the body. As scientist, Mikhail Tsaytin discovered in the 1970s, acrobats can successfully make a two person human tower in the dark, but after adding a third acrobat, not even the most talented can maintain the balance required to keep the tower intact while in the dark (1). What does darkness have to do with it? The point is that balance relies on at least three signals coming from the body, and one of those is sight. Once you eliminate one of these signals, the body cannot accomplish the required task. In addition to sight, signals coming from muscles and joints, called proprioceptors are sensitive to changes in position. The third contributor to the human tower and the topic of discussion of this paper is the vestibular system. A three-person human tower in the dark must not have enough information coming from the vestibular and proprioceptive systems to function without vision, whereas the two-person tower did have enough information.
This stage is divided into six substages are Simple Reflexes , Primary Circular Reactions , Secondary Circular Reactions , Coordination of Secondary Schemes , Tertiary Circular Reactions and Invention of New Means through Mental Combinations. These are described as : The first substage covers the first month after birth , it is dominating by the assimilation of sources of stimulation of inborn reflexes such as grasping or visual tracking (Rathus, S., & Longmuir, S., 2011 , p.81). The second substage is defined as primary circular reactions is focus on the infant’s own body rather than on the external environment . It lasts from about 1 to 4 (-in APA write out numbers under ten) month of age and is characterized by the beginning of the ability to coordinate various sensorimotor circular reaction(s). (space)In this (word missing) the infants focus changes from focusing on themselves to focusing on the external environments and this includes objects (Rathus, S., & Longmuir, S., 2011 , p.82) . During the fourth stage infants tends to imitate gestures and sounds that they had previously ignored and they also coordinates to attain a specific goals , for example trying to picking up the objects (Rathus, S., & Longmuir, S., 2011 ,
Sensation, as we know it, is thought to be a result of direct contact between the body and an internal or external stimulus. However, in the case of phantom limb phenomenon, sensation is explained rather differently. The phantom limb phenomenon, in short, occurs when a person with a missing limb still has sensations of limb being there; it is having the perception of missing limbs and feeling sensations from i...
A tactile learner best understands things when physical activity is incorporated in their classes and study sessions. I am a tactile learner, this means that I learn best using hands-on learning rather than listening to lectures or watching demonstrations. Physical movement helps tactile learners better comprehend and remember what they’re being taught in class. Personally, I find it easier to understand complex concepts by building them. In physics class last year we were assigned many labs. We had to make airplanes to explain a principle regarding aerodynamics. I was able to understand the principle better when I could see how the airplane was effected. Kinesthetic intelligence is very similar to being a tactile learner, people who possess
In order to better understand vertigo, it is first necessary to look into where equilibrium and movement are maintained within the body. Equilibrium in our bodies is coordinated primarily by the brain, specifically at the brainstem, located in the neck area. The environment provides the information necessary for the equilibrium center to determine which position to place the body in. There are three main places in which information is received: the eyes provide visual information, the ears provide vestibular and auditory information, and the articulations provide proprioceptive information. In general, the eyes help position the body according to different horizontal angles in relation to the ground. The ears allow the body to acknowledge any type of movement, such as acceleration or deceleration, by registering various sounds (1). Movement is also processed in parts of the brain, as well as in the ears. The frontal lobes of the brain initiate and coordinate the planning of movements. The basal ganglia, in the ears, add control and fluidity to movements, and the cerebellum processes information from and to the rest of the body.
During the birth to two years stage children are learning about the world through their sensations and through their movements. One of the most influential theorist’s Jean Piaget developed four important stages of cognitive development. In the first stage, known as the sensorimotor stage, direct sensory experiences are occurring. Motor actions are occurring as well, which are important for the learning of children as they get older. Since infants at this age are learning through their movements they are using basic actions such as grasping onto objects with their hands, sucking, listening and observing the world around them. With these movements, they are beginning to understand that their actions cause things to happen around them. When this
A child begins to correlate motor patterns and sensory input. For example a child may unintentionally suck her thumb, if she enjoys the sensation she will do this again.
