Sensations are possible due to the process of capturing and transforming information from the environment into energy recognized as such by the nervous system.
Sensations are always ahead of time-scale perceptions. Perceptions represent the interpretation of captured information, giving them a sense. Stimulus is all that information that acts directly or indirectly on our sense organs.
Forms of sensations, perceptions – after the organ of feeling: sensations and hearing perceptions (ears)
Differential threshold – the minimum amount added or low that makes the difference between sensations of the same kind.
Sensory attack – is the increase or decrease in sensitivity as a result of repeated stimulation. Sensory Contrast – is the body’s ability to value two or more stimuli different in intensity.
The absolute minimum- maximum threshold is the minimum or maximum amount added or low that makes the difference between sensations of the same kind.
It occurs when a sensation of a certain type influences another type of sensation in the sense of diminishing or accentuating it.
