Sensation - How we detect physical energy from the environment and encode it as neural signals. Perception - Process of organizing and interpreting sensory info. Transduction - Conversion of one form of energy to another form. There are 3 steps every time you convert sensory energy to get the info to your brain.

The "absolute threshold of sensation" refers to the minimum intensity of a stimulus that a person can detect half the time.

The Key Points of Weber’s Law.

These are the key points that they continue to come back to: The just noticeable difference between two stimuli.Signal Detection Theory is a psychophysical model that explains how humans make decisions based on sensory information.
