Eyeblink conditioning
Eyeblink Conditioning
Eyeblink conditioning (pronounced: /ˈaɪˌblɪŋk ˌkɒndɪˈʃəʊnɪŋ/) is a form of classical conditioning that involves pairing a previously neutral stimulus with a stimulus that naturally elicits an eyeblink response. The neutral stimulus eventually comes to elicit the eyeblink response on its own. The term is derived from the Greek words "ophthalmos" (eye) and "blink", and the Latin word "condicionem" (conditioning).
Process
The process of eyeblink conditioning involves two main components: the unconditioned stimulus (US) and the conditioned stimulus (CS). The US is a stimulus that naturally and automatically triggers an eyeblink response, such as a puff of air directed at the eye. The CS is a previously neutral stimulus that, after being repeatedly paired with the US, comes to trigger an eyeblink response on its own. This could be a sound, a light, or any other stimulus that does not naturally trigger an eyeblink response.
Types
There are two main types of eyeblink conditioning: delay conditioning and trace conditioning. In delay conditioning, the CS and US overlap, with the CS beginning before and ending at the same time as the US. In trace conditioning, there is a gap between the end of the CS and the beginning of the US.
Applications
Eyeblink conditioning has been used in research to study the neural mechanisms of learning and memory. It has also been used to study the effects of aging and neurological disorders on these processes.
