Spatial discrimination: allows us to recognize submodalities of a particular sensation.
Perceptual detection: is the simplest level of sensation
Magnitude estimation: is the ability to detect how much stimulus is applied to the body.
Pattern recognition: allows us to see a familiar face.
Explanation:
Spatial discrimination allows a person to built espacial relations, this means to localize a stimuli in different modalities in a different spaces.
Perception is the way any stimuli is first recibed, by the brain receptors. Is the first way a stimuli enters the brian.
Magnitud estimation: has to do with a way of perception to but it works to detect de amount of stimuli the body is receiving.
Pattern recognition: when perception works fine, the brain works to learn repetition or familiar stimulis, and this is how patterns are built and then recognition of them appear. This is a fundamental process of devepolment when a baby first recongnizes his mother's face for example.
