Conditioned Stimulus (CS)

Unconditioned Response (UCR)

Every time you take a shower, someone in your apartment flushes a toilet, causing the water to become scalding hot. You naturally jump back from the hot water. After this happens several times, you begin to jump back as soon as you hear the toilet flush, even before the water temperature changes. In this scenario, which element is the stimulus that automatically triggers a reflexive response without any prior learning?

Example of Classical Conditioning Processes: The Ice Cream Truck

A researcher is training a rat in a special cage. The researcher plays a specific tone, and two seconds later, a small food pellet is dispensed. Initially, the rat ignores the tone. After 30 trials, the researcher observes that the rat now approaches the food dispenser as soon as the tone is played. Which statement best analyzes this initial learning phase?

A researcher is training a pigeon to peck a key for a food reward. In the initial phase of the experiment, a red light is turned on for two seconds, immediately followed by the delivery of a food pellet. This procedure is repeated multiple times. After several trials, the researcher observes that the pigeon begins to approach the food dispenser as soon as the red light comes on. Which statement best describes this initial phase of the experiment?
