Psychophysics

Found by Gustav Fechner in 1860

It deals with the relationship between physical stimuli and their

perception.

He is interested in the point wherein we are aware that we are

sensing something.

Example:

You may be reading your lessons while listening to the radio.

If you are focused on what you are reading, you may forget that

you are having music on your ear.

If you are bored, you listen to the music more than reading the

book.

Threshold for Sensation and Perception

Absolute Threshold

Detection Threshold

The weakest possible stimulus that the person can conceive

Difference Threshold

Just Noticeable Difference

the minimum difference in stimulation that a person can detect 50 percent of the time

Examples:

1. You place a pile of sand on your

hand and I added more. The difference

between the weight of the sand you

have that and the amount of sand after

I added it, is the difference threshold.

2. You are listening to music at volume 55, then I turned it to volume 75. You covered your

ears because its loud. The difference of the volume is the difference threshold.
