Senses Flashcards
What is the sensory experience? What does it consist of?
The sensory experience consists of two components: reception and perception.
Sensory reception receives date about the external or internal environment through the senses.
Sensory Perception is the conscious process of selecting organizing and interpreting data from the senses into meaningful information.
What senses are used foe sensory perception?
vision, hearing, smell, taste and touch
What is Stereognosis?
Its the sense that perceives the solidity of objects, their size, shape and texture.
What senses does a person use to orient themselves internally?
The kinesthetic and visceral senses.
What does Kinesthesia refer to?
Awareness of positioning of body parts and body movement.
What does Visceral pertain to?
Inner organs.
What is Proprioception?
A term used to describe the sense, usually at a subconscious level, of the movements and position of the body and especially its limbs, independent of vision.
What are the four conditions that need to be met for a person to be able to receive the necessary date to experience the world?
1) A stimulus - something capable of imitating a response.
2) A receptor - to receive the stimulus and turn it into a nerve impulse.
3) The nerve impulse needs to be conducted a long a pathway from the receptor to the brain.
4)An area in the brain must receive and translate the impulse into a sensation.
What is meant by the term ‘Adaptation” when it comes to our senses?
The body way of quickly adapting to constant stimuli for example noise from a sound machine that you do not hear after a while of being exposed to it.
What is sensory deprivation?
Sensory deprivation occurs when a person experiences decreased sensory input or input that is monotonous, unpatterned, or meaningless. With decreased sensory input, the RAS is no longer able to project a normal level of activation to the brain. As a result, the person may hallucinate simply to maintain an optimal level of arousal.
What patients are at a greater risk of sensory deprivation?
Patients in an environment with decreased or monotonous stimuli (ex. in an institution)
Patients in an environment with decreased or monotonous stimuli (ex. impaired vision)
Patients in an environment with decreased or monotonous stimuli (ex. brain damage)
What are treatments for sensory deprivation?
Maintain sufficient level of arousal by increasing sensory stimuli from all sensory modalities.
Colorful sheets, pajamas, robes.
Reading to the patient.
Food of different textures, colors, temperatures.
Hugs.
Orient the patient to the environment.
Encourage the patient to share fears, concerns, and perceptions.
What is sensory overload?
Sensory overload is excessive stimuli over which a person feels little control; the brain is unable to meaningfully respond to or ignore stimuli.
What is sensory deficit?
Impaired or absent functioning in one or more senses.
examples are : impaired sight and hearing, altered taste, numbness and paralysis that result in altered tactile perception, and impaired kinesthetic sense.
What is a sensory processing disorder?
A difficulty in the way the brain takes in, organizes, and uses sensory information, causing a person to have problems interacting effectively in the everyday environment.
