Sensation and perception

There needs to be a differentiation between sensation and perception. Sensation is purely sense data, and perception is processed data. Sensation can one of five (there are more) basic sense data from the eye, ear, nose, skin and tongue, in the form of sight, sound, smell, touch and taste. Perception is the processed from these five senses as well as from the mental data (thought and concepts).

A video camera and its connected monitor is like sensation. The video camera thinks  nothing of the signal coming through its system, only to pass it down a wire to a monitor to be displayed. Certain limitations are placed upon the data through how it is displayed on the monitor but nothing more.

A processing unit attached to the monitor then can analyse, organise and categorise the data in the form of light that is formed as a representation of the external world. A video/monitor unit is useless without the processing unit. And the processing unit is useless without some kind of data.

In this way, the video/monitor unit is the experiential component while the processing unit is the rational component of the transcendental idealist model.

      True. In philosophy also. But most non-psychologists and non-philosophers tend not to make that distinction or not to think it important.
