SD329 Block 1

We obtain all our experience of the external world through our ❌. The development of the brain from birth onwards, particularly in the ❌, depends crucially on the information received from the senses. Extended periods of ❌ can lead to permanent ❌ of the brain

Sensory processing comprises two overlapping stages: first, ❌ of the sensory stimulus, called ‘❌’, and second, the ❌ of a mental ❌ of the sensory environment, called ‘❌’.

The mental ❌ formed from sensory information is referred to as a ❌, and is the result of a range of processes including context, ❌ and past ❌.
It is possible to investigate the process of ❌ using illusory figures, which are able to separate ❌ from perception.

Our interpretation of the ❌ requires more than the ❌ of individual sensory signals. Rather, we make a number of ❌ about our environment, such as what features should remain ❌, and use a number of different ❌, for example interposition, to perceive a ❌.

The processes of ❌, perception and motor ❌ allow us to actively engage with our sensory ❌ and learn about it, so as to inform ❌ actions.

The ❌ senses consist of a wide range of different types of ❌ providing information about the external ❌ world and about the ❌ itself.
In the case of touch and ❌, the receptors are located ❌ the body. By contrast, receptors for ❌ are rather more limited in their locations, being found in joints, ❌ and tendons.

The sense of hearing is a ❌ sense and involves sound waves stimulating ❌ found in the ear. The characteristics of the ❌ relate to the ❌ features of the ❌, such as the ❌ of a musical note.

The ❌ system detects ❌ information (important for balance) but is often considered separately because it relates entirely to the position of the ❌.

❌ is a ❌ sense and involves a ❌ signal entering the eye and stimulating ❌ in the ❌. As with hearing, the characteristics of the light wave affect the ❌ characteristics.

Smell and taste are often referred to as the ❌ senses because they require ❌ interactions as a stimulus. They are intimately ❌ and, when combined, give rise to the perception of ❌.

People who have ❌ involving their sense of ❌ are very rare. Lack of the sense of ❌ can lead to ❌ since, if pain is absent, there is no early ❌ signal that the body is at risk.

Sensory ❌ associated with vision and hearing are considerably more ❌ than other sensory impairments, and clearly illustrate the different extents to which deficits may occur. For example, some individuals are unable to hear certain ❌ and others are totally ❌; visual impairments range from ❌ to total ❌.

Impairments of ❌, although seemingly less problematic than disorders of the other senses, can have a substantial effect on a person’s ❌ of life. They can affect the ❌, as well as introduce dangers caused by the inability to detect gas, or smoke or spoiled food. The noticeable loss of the sense of smell or taste may be the first indication of an ❌, leading to earlier diagnosis and treatment than might otherwise be the case – for example, the early warning of the onset of ❌ disease.
