There exists different measures to estimate reaction time. They include:
- simple reaction time
- choice reaction time

Cognitive psychology: Connecting mind, research and everyday experience

A lot of what someone experiences is not based on direct stimuli, rather representations in the nervous system

Principle of Neural representation

Processing in perception

Created by Thomas Bayes, who posited that our estimate of the probability of an outcome was determined by two things:
- 1) prior probability of an outcome 
- 2) likelihood of an outcome

Bayesian Inference

The ability to (mentally) recreate the sensory world in the absence of external stimuli. People can imagine tastes, smells and experiences

Mental Imagery

The study of perception involves multiple levels of analysis, extending from fundamental biological mechanisms to behavioral outcomes. These levels include:
1) Chemical processes
2) Activation of individual neurons
3) Activation of specific brain structures
4) Activation of interacting groups of brain structures
5) The conscious experience of perception
6) The resulting behavioral output or action
