Animal Sensory Systems and Behavior

A non-stimulating environment, such as one that severely restricts physical activity and limits social contact with family and friends, can lead to sensory deprivation.

Considering the client's individual needs and compatibility with roommates is crucial in preventing sensory overload.

Examples of stimuli include electronic devices, clocks or calendars, reading materials, and a suitable number of roommates and visitors.

<p>An individual's cultural background can influence their perception of sensory stimulation by determining what they consider as normal or usual levels of stimulation. For example, individuals from a big-city neighborhood may be accustomed to more stimulation than those from a suburban area. The implications for their well-being are that they may seek to increase or decrease stimulation accordingly, and healthcare professionals should be aware of these cultural differences to provide appropriate care.</p> Signup and view all the answers
